Occupational therapy (OT) for Parkinson's disease is a specialized form of rehabilitation that focuses on maintaining independence in activities of daily living (ADLs), instrumental ADLs (IADLs), and overall quality of life. Occupational therapists utilize task-specific training, compensatory strategies, and environmental modifications to address both motor and non-motor symptoms that affect functional ability in individuals with Parkinson's disease. [@radder2020]

The progressive nature of Parkinson's disease leads to increasing challenges in self-care, mobility, and participation in meaningful activities. OT provides personalized interventions that target the specific functional limitations experienced by each individual, taking into account disease stage, symptom severity, and personal goals. Evidence-based OT interventions have demonstrated significant improvements in motor function, daily activities performance, and quality of life measures. [@sturkenboom2022]

Evidence-Based Interventions

LSVT BIG Therapy

Lee Silverman Voice Treatment BIG (LSVT BIG) is a specialized amplitude-based behavioral treatment designed to counteract bradykinesia (slowness of movement) through intensive, repetitive exercises that emphasize large-amplitude movements. The therapy was adapted from the well-established LSVT LOUD speech therapy protocol and focuses on training patients to move "bigger" in all daily activities. [@farley2015]

Protocol:

• Intensive phase: 4 sessions per week for 4 weeks (16 total sessions)
• Session duration: 60-90 minutes
• Daily homework: 30-60 minutes of practice daily
• Maintenance: Regular practice to sustain gains

Clinical Outcomes:

• Improved gait speed (10-20% increase)
• Enhanced balance and reduced fall risk
• Better performance in daily functional activities
• Increased movement amplitude in upper extremity tasks
• Improved trunk rotation and postural control

LSVT LOUD for Speech and Swallowing

While primarily focused on voice and speech, LSVT LOWD also has significant applications for swallowing function (dysphagia) in Parkinson's disease. Occupational therapists often collaborate with speech-language pathologists to address both speech and swallowing impairments using this framework.

Task-Specific Training

Task-specific training involves practicing real-world activities that are meaningful to the patient rather than isolated exercises. This approach is grounded in the principle of neuroplasticity—the brain's ability to reorganize and form new neural connections through repeated, purposeful practice. [@capato2021]

Core Principles:

• Repetition: High numbers of practice repetitions to drive motor learning
• Specificity: Training directly targets the tasks of interest
• Progressive difficulty: Gradually increasing challenge as skills improve
• Context: Practice in realistic environments with relevant stimuli

• Sequencing practice: Breaking complex tasks into component parts and practicing each
• Dual-task training: Combining motor and cognitive tasks to improve divided attention
• Cueing strategies: Using visual, auditory, or tactile cues to facilitate movement initiation

Compensatory Strategies

Compensatory strategies are techniques that help patients work around their limitations rather than attempting to restore normal function. These strategies are particularly valuable in moderate to advanced Parkinson's disease where full restoration of movement may not be possible.

Movement Compensations:

• Visual cueing: Stepping over lines on the floor, using laser pointers
• Auditory cueing: Rhythmic counting, metronomes, music
• Tactile cueing: Light touch to initiate movement, weighted objects
• Mental rehearsal: Visualization before attempting movements

• Pacing: Breaking tasks into manageable chunks with rest periods
• Prioritization: Focusing on essential activities and deferring less critical tasks
• Delegation: Asking for assistance with tasks that are unsafe or overly fatiguing
• Equipment: Using adaptive devices to reduce physical demands

Environmental Modifications

Modifying the home and work environment can significantly improve safety and independence for individuals with Parkinson's disease.

Bathroom Modifications:

• Grab bars and handrails near toilet and in shower
• Raised toilet seats
• Shower chairs and transfer benches
• Non-slip mats and flooring
• Walk-in showers with low thresholds

• Lazy Susans and pull-out shelves for easier access
• Lightweight cookware and utensils
• Electric can openers and kitchen aids
• Lever-style faucet handles
• Contrasting colors to improve visibility

• Removing throw rugs and securing carpets
• Improving lighting throughout the home
• Clearing walkways and removing clutter
• Installing ramps if mobility aids are used
• Using a shower chair and hand-held showerhead
