1. What Is Parkinson’s Disease?

Parkinson’s disease (PD) is a progressive neurodegenerative condition that primarily affects movement. It develops when dopamine-producing neurons in the substantia nigra — a specific region of the brain involved in coordinating smooth, controlled movement — gradually degenerate, resulting in reduced dopamine availability and impaired motor control (Willis et al., 2022).

The hallmark motor symptoms of Parkinson’s disease include resting tremor (shaking that occurs when the body is at rest), rigidity (muscle stiffness), bradykinesia (slowness of movement), and postural instability (difficulty maintaining balance). Symptoms typically begin asymmetrically — affecting one side of the body before the other — and progress over time (Willis et al., 2022).

In addition to motor symptoms, Parkinson’s disease involves a wide range of non-motor features, including depression, anxiety, cognitive changes, sleep disruption, autonomic dysfunction (affecting blood pressure, bladder, and bowel function), and swallowing difficulties. These non-motor symptoms often have a substantial impact on daily functioning and quality of life and are increasingly recognized as a core part of the condition rather than secondary concerns (Willis et al., 2022).

Approximately 90,000 individuals in the United States are newly diagnosed with Parkinson’s disease each year, with prevalence projected to reach 1.2 million by 2030. Rehabilitation, therapy, and exercise play a central role in managing PD and maintaining independence across all stages of the disease (Willis et al., 2022).

Parkinson’s Disease Is More Than a Movement Disorder

While Parkinson’s disease is often described primarily as a movement condition, research now recognizes it as a complex, whole-body neurological condition. Non-motor symptoms — including depression, anxiety, cognitive changes, fatigue, sleep disorders, and autonomic dysfunction — frequently precede motor symptoms and often have a greater impact on daily life than the movement changes. A comprehensive rehabilitation approach addresses both motor and non-motor dimensions of the condition (Willis et al., 2022).

2. How Is Parkinson’s Disease Diagnosed and Staged?

Parkinson’s disease is diagnosed clinically — based on medical history and neurological examination — rather than through a definitive laboratory test or imaging study. A neurologist or movement disorder specialist evaluates symptom presentation, progression, and response to dopaminergic medication (Willis et al., 2022).

Clinical diagnosis relies on the presence of bradykinesia (slowness of movement) combined with either resting tremor or rigidity, with supportive features including asymmetry of symptoms and a positive response to dopaminergic medication such as levodopa. Diagnosis is typically confirmed only when multiple criteria are met and other causes have been excluded (Willis et al., 2022).

An important clinical consideration is that diagnosis often occurs after significant dopamine loss has already taken place — the brain’s early compensatory mechanisms can mask symptoms in the initial stages, meaning the disease has been progressing for some time before the first noticeable symptoms appear (Willis et al., 2022).

Staging tools used in clinical practice include the Hoehn and Yahr scale, which describes disease progression from mild unilateral symptoms through to more advanced functional impairment, and the MDS-UPDRS (Movement Disorder Society Unified Parkinson’s Disease Rating Scale), which provides a comprehensive assessment of motor and non-motor symptoms and is widely used in both clinical practice and research settings (Willis et al., 2022).

For Patients & Families

  • A diagnosis of Parkinson’s disease should be made by a neurologist or movement disorder specialist — a movement disorder specialist has additional subspecialty training in PD and related conditions and may offer access to specialized therapies and clinical trials
  • Receiving a PD diagnosis is life-changing — give yourself and your family time to process it. Connecting with the Parkinson’s Foundation (parkinson.org) or the Michael J. Fox Foundation (michaeljfox.org) early provides access to education, support, and resources
  • A baseline evaluation by OT, PT, and SLP at or near diagnosis — even when symptoms are mild — establishes a functional baseline and allows for proactive planning before difficulties emerge
  • Staging is not destiny — many people with PD remain highly functional for many years with appropriate exercise, therapy, and medical management

3. Who Provides Therapy for People with PD?

Parkinson’s disease is best managed through a multidisciplinary approach because its impact on motor, cognitive, and functional systems requires coordinated intervention across disciplines. No single provider can address all of the rehabilitation needs that arise across the course of the condition (Doucet et al., 2021).

  • Occupational therapy (OT): Daily activities, independence, safety, fine motor function, cognitive strategies, adaptive equipment, and participation in meaningful roles
  • Physical therapy (PT): Gait, balance, strength, endurance, mobility, and fall prevention
  • Speech-language pathology (SLP): Communication disorders (voice, speech intelligibility, language), swallowing dysfunction (dysphagia), and cognitive-communication
  • Neurology/movement disorder specialist: Medication management, medical monitoring, and coordination of the overall care plan
  • Neuropsychology: Assessment and treatment of cognitive changes, depression, anxiety, and behavioral symptoms
  • Social work: Community resource navigation, caregiver support, financial planning, and care coordination

Evidence supports early and proactive referral to rehabilitation services — multidisciplinary care improves functional outcomes and quality of life and is most effective when initiated early, before significant functional decline has occurred (Doucet et al., 2021; Doucet & Franc, 2023).

For Clinicians

  • Multidisciplinary referral at or near diagnosis is best practice — waiting until significant functional decline has occurred reduces the benefit and increases the burden of rehabilitation (Doucet et al., 2021).
  • PD-specific training matters — LSVT BIG (OT/PT) and LSVT LOUD (SLP) require certified practitioners. When referring, specify PD-trained or LSVT-certified providers when available.
  • Reassess rehabilitation needs at every major disease transition — medication changes, falls, hospitalizations, and new symptom onset are all triggers for re-referral.
  • Caregiver strain increases significantly as PD progresses — proactive social work and caregiver support referral should be part of every care plan.

4. Occupational Therapy in Parkinson’s Disease

Occupational therapy focuses on maintaining independence in meaningful daily activities — dressing, grooming, meal preparation, medication management, handwriting, driving, and community participation. Systematic reviews demonstrate that OT interventions improve activities of daily living (ADLs) and quality of life in individuals with Parkinson’s disease across physical, emotional, and participation domains of daily life (Doucet et al., 2021; Tofani et al., 2020).

Key Areas of OT Intervention:

  • Activities of daily living (ADLs): Task modification, energy conservation strategies, and habit training to maintain independence in self-care and domestic tasks
  • Fine motor skills: Addressing micrographia (abnormally small, cramped handwriting common in PD), dexterity, and coordination for tasks such as buttons, zippers, and utensil use
  • Adaptive equipment: Weighted utensils, button hooks, pen grips, jar openers, and other tools to support independence when motor symptoms affect functional performance
  • Home safety: Environmental assessment and modifications to reduce fall risk [LINK TO: fall-prevention page] and support safe daily function
  • Cognitive strategies: External cues, routines, visual schedules, and compensatory strategies for the attention and executive function changes that occur with PD
  • Caregiver training: Teaching caregivers how to support independence without enabling dependence — one of the highest-yield OT interventions in PD

LSVT BIG®

LSVT BIG is an intensive, amplitude-based OT/PT intervention designed specifically for Parkinson’s disease. It targets movement size and quality — training larger, more forceful movements to counteract the characteristic small, shuffling movements of PD. Randomized controlled trials demonstrate significant improvements in gait speed, balance, and functional mobility following LSVT BIG (Eldemir et al., 2024; Kaya Aytutuldu & Birinci, 2024). Telerehabilitation-based delivery of LSVT BIG has also shown equivalent outcomes to in-person delivery, increasing access for patients with transportation or mobility barriers (Kaya Aytutuldu & Birinci, 2024).

For Patients & Families

  • Difficulty with daily tasks like dressing, writing, or cooking is common in Parkinson’s disease — these challenges are often highly treatable with the right strategies and adaptive tools
  • Small adaptations make a big difference — larger-handled utensils, button hooks, weighted pens, and grab bars can maintain independence for years longer than managing without them
  • Occupational therapy helps people stay independent longer — don’t wait until tasks become impossible before requesting a referral. Early OT prevents decline rather than just responding to it
  • Ask your OT specifically about LSVT BIG if motor symptoms are affecting your daily movement — it is the most evidence-based OT/PT approach for PD and requires a certified provider

For Clinicians

  • A systematic review and meta-analysis confirmed that OT interventions improve quality of life across physical, emotional, and participation domains in PD — not just ADL performance (Tofani et al., 2020).
  • LSVT BIG requires certification — confirm provider credentials when referring. Both in-person and telerehabilitation delivery produce equivalent outcomes (Kaya Aytutuldu & Birinci, 2024).
  • Micrographia and fine motor changes often precede significant gross motor symptoms — early OT intervention for handwriting and dexterity supports continued independence in medication management, financial tasks, and communication.
  • Medication “on/off” state significantly affects functional performance — schedule OT assessments during “on” periods for optimal performance data, and during “off” periods to understand real-world functional limitations.

5. Physical Therapy and Exercise for Parkinson’s Disease

Exercise is one of the most strongly supported interventions in Parkinson’s disease rehabilitation and is recommended across all disease stages — not only for motor symptoms but also for mood, cognition, sleep, and overall quality of life. A Cochrane network meta-analysis of 156 randomized controlled trials found that multiple forms of exercise improve motor symptoms and quality of life in people with PD (Ernst et al., 2023).

Physical therapy focuses on gait retraining, balance training, strength and endurance, transfer training, and fall prevention. PT intervention is individualized based on disease stage, symptom profile, and the person’s functional goals — and should be initiated early to establish movement patterns and exercise habits before significant decline occurs.

Evidence-Based Exercise Approaches:

  • Gait and balance training: Including treadmill training, cueing strategies (visual and auditory cues to improve step length and rhythm), and dual-task training — practicing walking while performing a cognitive task to reflect real-world demands
  • Aerobic exercise: Including cycling, walking, and swimming — associated with improvements in motor symptoms, mood, cognitive function, and neuroprotective effects
  • Resistance training: Targeting muscle strength, power, and endurance to counteract the muscle weakness and fatigue associated with PD
  • Dance and rhythmic movement: Tango and other partner dances have strong evidence for improving balance, gait, and quality of life in PD — the rhythmic external cue provided by music appears to particularly benefit PD gait patterns
  • Mind-body exercise: A systematic review found that tai chi, yoga, and qigong produce clinically meaningful improvements in motor function, balance, and gait in people with PD (Yang et al., 2023)

Regular participation in exercise is associated with improved physical function, reduced motor symptom burden, better mood, improved sleep, and potentially neuroprotective effects — making it among the most important self-management strategies available to people with PD (Ernst et al., 2023; Yang et al., 2023).

For Patients & Families

  • You do not need the perfect exercise program — consistency matters most. Walking, cycling, yoga, swimming, or dance can all be effective, and the best exercise is the one a person will actually do (Ernst et al., 2023)
  • Starting exercise early — before significant motor decline — helps maintain mobility, balance, and independence for longer. Exercise is most beneficial when it becomes a daily habit
  • A physical therapist with PD experience can design a safe, individualized program that addresses your specific symptoms, fall risk, and functional goals
  • Ask your PT about LSVT BIG — it is a specific, evidence-based program for PD that focuses on making movements bigger and is different from general physical therapy
  • Group exercise programs designed for PD — including Rock Steady Boxing, Dance for PD, and PWR!Moves classes — provide exercise benefits alongside social connection and peer support

For Clinicians

  • A Cochrane network meta-analysis of 156 RCTs confirmed that multiple exercise modalities improve motor symptoms and quality of life in PD — exercise prescription should be considered standard of care, not optional (Ernst et al., 2023).
  • Evaluate dual-task performance during gait assessment — cognitive-motor interference significantly contributes to fall risk in PD and is often missed in single-task assessments. The Timed Up and Go (TUG) with dual-task conditions is clinically useful.
  • Document medication “on/off” state during all assessments — functional performance can vary dramatically between states and assessment timing significantly affects interpretation of results.
  • Mind-body exercise modalities — tai chi, yoga, qigong — have meaningful evidence and high adherence rates. Including them in exercise recommendations broadens access and improves long-term participation (Yang et al., 2023).

6. Speech-Language Pathology in Parkinson’s Disease

Speech and voice impairments affect approximately 89% of individuals with Parkinson’s disease and typically worsen progressively over time (Perry et al., 2024). These changes — including reduced vocal loudness (hypophonia), monotone speech, imprecise articulation, and rapid or festinating speech — can significantly impact communication, social participation, and quality of life. Many people with PD are unaware of how significantly their voice has changed because the change occurs gradually.

LSVT LOUD®

LSVT LOUD (Lee Silverman Voice Treatment) is the most evidence-supported behavioral speech intervention for Parkinson’s disease. The program focuses on training one key target — speaking with a louder voice — which drives generalized improvements in articulation, facial expression, and swallowing through neuroplastic mechanisms. A systematic review of behavioral speech interventions for neurodegenerative disease found strong evidence supporting LSVT LOUD, with no other behavioral intervention demonstrating comparable effectiveness (Perry et al., 2024). A large, pragmatic randomized controlled trial — the PD COMM trial — demonstrated that LSVT LOUD produced significantly greater improvements in voice outcomes compared to standard NHS speech and language therapy (Sackley et al., 2024).

Dysarthria

Dysarthria — a motor speech disorder resulting from weakness and incoordination of the speech musculature — affects intelligibility, communication confidence, and social participation. SLP interventions beyond LSVT LOUD include breath support training, articulation exercises, rate control strategies, and augmentative and alternative communication (AAC) for individuals with severe dysarthria.

Dysphagia

Swallowing difficulties are common in Parkinson’s disease and may lead to serious complications including aspiration pneumonia (food or liquid entering the airway and lungs), malnutrition, dehydration, and significantly reduced quality of life. Dysphagia in PD is often underreported — many individuals with PD have silent aspiration and are unaware of swallowing difficulties until a complication occurs. Early identification through SLP screening and evaluation is essential for safety and health outcomes.

For Patients & Families

  • If your voice feels quieter, others frequently ask you to repeat yourself, or people seem to have difficulty understanding you — this is not just part of normal aging. It is a common and treatable consequence of PD (Perry et al., 2024)
  • Speech therapy — especially LSVT LOUD — can significantly improve vocal loudness, speech clarity, and communication confidence. The program is intensive but highly effective and requires a certified SLP
  • Early speech therapy treatment produces better outcomes — do not wait until speech is severely impaired. Request an SLP referral as soon as voice changes are noticed
  • Coughing or choking during meals, food sticking in the throat, taking longer to eat, or unexplained weight loss should all be reported to the care team promptly — these are signs of dysphagia that require SLP evaluation
  • Drooling — which is actually caused by reduced automatic swallowing, not excess saliva production — is common in PD and should also be discussed with the SLP and neurologist

For Clinicians

  • LSVT LOUD requires certification — the PD COMM RCT confirmed its superiority over standard speech therapy, making certified delivery essential for achieving published outcomes (Sackley et al., 2024; Perry et al., 2024).
  • Dysphagia in PD is frequently underreported and underdetected — routine swallowing screening at each clinic visit is appropriate, particularly in moderate-to-advanced disease. Silent aspiration is common and clinical bedside assessment alone may be insufficient.
  • The FEES (Fiberoptic Endoscopic Evaluation of Swallowing) or modified barium swallow study should be considered when clinical findings suggest aspiration risk — particularly before initiating texture modification or thickened liquids.
  • Hypophonia and reduced facial expression in PD can be misinterpreted by communication partners as cognitive impairment, depression, or disengagement — educating families and care teams about these motor speech features of PD reduces social isolation and improves interactions.

7. Non-Motor Symptoms

Non-motor symptoms are present throughout the course of Parkinson’s disease and often have a greater impact on quality of life than the motor symptoms that define the diagnosis. In many individuals, non-motor symptoms such as hyposmia (reduced sense of smell), constipation, REM sleep behavior disorder, and depression precede motor symptoms by years — sometimes decades (Willis et al., 2022).

Depression and anxiety are among the most common and most undertreated non-motor symptoms in PD. Approximately 40% of people with PD experience clinically significant depression and up to 40% experience anxiety at some point in the disease course. These are neurobiological conditions related to the brain changes caused by PD — not simply an understandable response to a difficult diagnosis. They respond to treatment and should be actively identified and managed (Willis et al., 2022).

Cognitive changes range from mild cognitive impairment — affecting attention, processing speed, and executive function — to PD dementia in later disease stages. Cognitive changes affect rehabilitation participation, ADL independence, and caregiver burden. OT cognitive rehabilitation and compensatory strategy training are highly relevant for managing these changes in daily life.

Sleep disorders — including insomnia, excessive daytime sleepiness, and REM sleep behavior disorder (acting out dreams, often with movement) — are common and significantly affect daily functioning and caregiver sleep. Sleep disturbance should be assessed and addressed as part of comprehensive PD management.

Autonomic dysfunction — including orthostatic hypotension (blood pressure drop on standing, which increases fall risk), constipation, urinary urgency, and sexual dysfunction — affects many people with PD and requires coordinated medical and rehabilitation management (Willis et al., 2022).

For Patients & Families

  • Non-motor symptoms are not separate from Parkinson’s disease — they are part of it, and they deserve the same clinical attention as tremor or walking difficulties
  • Depression and anxiety in PD are neurobiological — not a sign of weakness or inability to cope. They respond to treatment. Report mood changes to the neurologist promptly (Willis et al., 2022)
  • Cognitive changes — including slower thinking, difficulty multitasking, or memory challenges — are common in PD. Report these to the care team so appropriate assessment and strategies can be provided
  • If your loved one with PD appears to act out their dreams physically during sleep — moving, talking, or even getting up — report this to the neurologist. REM sleep behavior disorder is common in PD and may require medical management
  • Dizziness or lightheadedness when standing up is a sign of orthostatic hypotension and significantly increases fall risk — report this symptom to the neurologist

8. Falls and Home Safety

Falls are among the most serious complications of Parkinson’s disease and a leading cause of injury, hospitalization, loss of independence, and death in people with PD. The risk arises from a combination of postural instability, gait disturbances (festination — involuntary speeding up of steps, freezing of gait), reduced protective responses, and dual-task impairments. Orthostatic hypotension — a drop in blood pressure on standing — further increases fall risk (Ernst et al., 2023).

Exercise and rehabilitation interventions are among the most effective strategies for reducing fall risk. A Cochrane network meta-analysis confirmed that multiple forms of exercise improve functional mobility and are associated with reductions in motor symptom severity and fall risk (Ernst et al., 2023). Balance training and targeted exercise programs — particularly those that challenge balance under dual-task conditions — are among the most effective interventions available (Ernst et al., 2023).

Fall Prevention Strategies in Parkinson’s Disease:

  • Home modifications: Improved lighting, removal of loose rugs and clutter, installation of grab bars in bathrooms and stairways, non-slip surfaces, and raised toilet seats — see our Bathing & Shower Safety [LINK TO: bathing-shower-safety page] and Fall Prevention [LINK TO: fall-prevention page] pages for detailed guidance
  • Balance and strength training: Targeted PT programs that progressively challenge balance with and without dual-task demands
  • Gait cueing and movement strategies: Auditory cues (metronome), visual cues (floor markers), and mental strategies to manage freezing of gait
  • Medication timing: Falls more commonly occur during medication “off” states — ensuring consistent medication timing reduces fall risk
  • Footwear: Firm-soled, well-fitting shoes with thin soles — avoiding slippers, high heels, or shoes that shuffle
  • Assistive devices: Walking aids including wheeled walkers (rollators) may be appropriate in moderate to advanced PD — prescribed and fitted by a PT

For Patients & Families

  • Falls in PD are common but often preventable — home modifications, exercise, and therapy reduce risk significantly (Ernst et al., 2023)
  • Remove loose rugs, improve lighting, and install grab bars before a fall occurs — these are among the most effective and immediate protective measures available
  • Slowing down — especially when turning, getting out of chairs, or changing direction — is one of the simplest and most effective fall prevention strategies in PD
  • If freezing of gait occurs — that sudden inability to move the feet forward — try counting out loud, marching in place, or stepping over a visual target. A PT can teach you specific cueing strategies
  • After any fall, request a PT re-evaluation — falls in PD are a clinical indicator for reassessment of balance, gait, medication, and home environment

For Clinicians

  • Assess for orthostatic hypotension at every visit in patients with PD — a drop in systolic BP of ≥20mmHg or diastolic BP of ≥10mmHg on standing is clinically significant and should be addressed medically and behaviorally.
  • The TUG with dual-task conditions (e.g., counting backwards while walking) is more sensitive for fall risk in PD than the standard TUG — include dual-task conditions in every mobility assessment.
  • Freezing of gait is a distinct phenomenon from bradykinesia and requires specific intervention — cueing strategies, anti-freezing devices, and environmental modification. Adjust management based on whether freezing is predominantly “on” state or “off” state freezing.
  • Document fall history at every visit — frequency, circumstances, injuries, and near-falls. Falls in PD are underreported and the data are essential for appropriate referral and management.

9. Living with Parkinson’s Disease

Parkinson’s disease does not eliminate independence or quality of life. With appropriate support, intervention, and self-management, many individuals maintain meaningful participation in daily life, work, relationships, and community for years and decades after diagnosis. The trajectory of PD is highly individual — no two people experience the condition in exactly the same way, and prognosis is influenced by many factors including age of onset, symptom profile, access to treatment, and engagement in exercise and rehabilitation (Willis et al., 2022; Ernst et al., 2023).

Consistent exercise and rehabilitation are among the most powerful tools available — associated with improvements in motor function, daily activity performance, quality of life, mood, sleep, and cognitive function. The evidence is clear that people with PD who exercise regularly do better across virtually every outcome measure that matters (Ernst et al., 2023; Doucet et al., 2021).

Key Strategies for Living Well with PD:

  • Engage in regular, structured exercise — daily if possible, using a variety of modalities
  • Seek early and ongoing multidisciplinary therapy — OT, PT, and SLP at or near diagnosis and at every major transition
  • Address speech and voice changes early — before they significantly affect social participation and relationships
  • Modify the home environment proactively — before falls or functional decline make modifications urgent
  • Address non-motor symptoms — depression, anxiety, sleep, and cognitive changes — with the same seriousness as motor symptoms
  • Connect with the PD community — Parkinson’s Foundation, Michael J. Fox Foundation, local support groups, and disease-specific exercise programs
  • Involve caregivers in the rehabilitation process — informed caregivers who understand how to support active participation make a measurable difference in outcomes

10. What Families Can Do

Family members and caregivers are essential partners in Parkinson’s disease management. The support, encouragement, and practical assistance of family directly influences how well a person with PD manages their symptoms, adheres to exercise and therapy, and maintains their quality of life (Doucet et al., 2021).

  • Learn about Parkinson’s disease together: Understanding the condition — its motor and non-motor symptoms, its progression, and its management — helps both the person with PD and their family make informed decisions and plan effectively
  • Encourage independence: Resist the urge to do things for your loved one that they can still do for themselves — maintaining independence, even when it takes longer or looks different than before, is clinically important for both function and dignity
  • Support consistent exercise: Exercise adherence in PD is significantly improved by social support. Walking together, attending exercise classes, or simply encouraging daily activity makes a real difference
  • Attend therapy appointments: Learning strategies from the OT, PT, and SLP allows you to reinforce them at home and advocate effectively for your loved one’s needs
  • Watch for non-motor changes: Depression, anxiety, cognitive changes, and sleep disorders in PD are easily overlooked — family members are often the first to notice these changes and should report them to the care team
  • Seek caregiver support for yourself: Caregiver burden in PD is significant and increases as the disease progresses. Parkinson’s Foundation caregiver resources, support groups, and respite care services are available — use them

When to Request a Therapy Referral

  • At or near diagnosis — for baseline assessment, education, and proactive planning before functional decline occurs
  • When daily tasks become more difficult — dressing, writing, cooking, managing medications, or other ADLs
  • When speech or voice changes are noticed — quieter voice, difficulty being understood, or others asking for repetition
  • After any fall, near-fall, or increasing fear of falling
  • When balance, walking, or mobility feels less stable or confident
  • When freezing of gait occurs — sudden inability to move the feet forward
  • When cognitive changes begin to affect daily function — attention, planning, or multitasking difficulties
  • When swallowing changes occur — coughing during meals, food sticking, taking longer to eat, or unexplained weight loss
  • During any major change in condition — new symptoms, medication changes, hospitalization, or significant functional decline

11. A Note for Clinicians

Parkinson’s disease rehabilitation is most effective when multidisciplinary, initiated early, and maintained proactively throughout the disease course. The evidence supporting exercise and rehabilitation in PD is among the strongest in all of rehabilitation medicine — a Cochrane network meta-analysis of 156 RCTs confirmed exercise benefits, and systematic reviews support OT and SLP interventions across multiple domains (Ernst et al., 2023; Doucet et al., 2021; Perry et al., 2024).

The gap between evidence and practice remains clinically significant. Many people with PD are not referred to OT, PT, or SLP until functional decline is substantial — at which point the benefit of rehabilitation is reduced and the burden is greater. Proactive referral at or near diagnosis, and re-referral at every major transition, is best practice (Doucet et al., 2021; Doucet & Franc, 2023).

LSVT BIG and LSVT LOUD are the most evidence-based PD-specific therapy programs available and require certified practitioners. When referring patients to OT, PT, or SLP for PD, specifying LSVT certification where available ensures that patients receive the highest-evidence interventions rather than generic therapy (Eldemir et al., 2024; Perry et al., 2024; Sackley et al., 2024).

Non-motor symptoms — particularly depression, anxiety, and cognitive changes — remain undertreated in PD. Systematic screening at every visit, using validated tools such as the GDS (Geriatric Depression Scale), GAD-7, and MoCA, supports timely identification and treatment. The neuropsychological burden of PD is substantial, and addressing it directly improves rehabilitation participation and functional outcomes (Willis et al., 2022).

Caregiver education and training should be built into every PD rehabilitation plan. As the disease progresses, caregiver strain increases substantially. Informed caregivers who understand how to support active participation — rather than enabling learned helplessness — produce better outcomes for both the person with PD and themselves (Doucet et al., 2021).
