Physical therapy and occupational therapy are essential components of comprehensive care for Atypical Parkinsonism, specifically Corticobasal Syndrome (CBS) and Progressive Supranuclear Palsy (PSP). While these conditions are progressive and currently incurable, targeted rehabilitation interventions can significantly maintain function, reduce complications from falls, and improve quality of life throughout the disease trajectory

This page focuses specifically on evidence-based physical therapy and occupational therapy interventions for CBS and PSP, covering gait training, balance therapy, fall prevention strategies, LSVT BIG therapy, constraint-induced movement therapy, adaptive equipment, and home modifications. The content is designed for healthcare professionals, caregivers, and patients seeking practical, actionable rehabilitation guidance.

The rehabilitation approach must be individualized based on disease type (CBS vs. PSP), clinical variant, disease stage, and specific symptom profiles. Early intervention yields the greatest functional benefits, but meaningful improvements are possible at any stage

Evidence Base for Rehabilitation in Tauopathies

Rationale for Exercise in CBS/PSP

CBS and PSP are 4R tauopathies characterized by abnormal tau protein accumulation in neurons and glia. While disease-modifying therapies remain elusive, physical rehabilitation offers a complementary approach to symptom management and functional preservation. The evidence base, while smaller than for Parkinson’s disease, supports the safety and potential benefits of exercise in these populations^{3Effects of group, individual, and home exercise in persons with Parkinson disease (2015)2015 · PMID 26414620Open reference4Exercise for preventing falls in older people living in the community (2019)2019 · PMID 30677159Open reference}.

Key evidence findings:

• Allied health therapy, including physical therapy, demonstrates effectiveness in managing symptoms of progressive supranuclear palsy^{5Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy (2016)2016 · PMID 27532657Open reference}

• Exercise appears safe for PSP patients, with no evidence of harm from physical activity interventions^{6Exercise and physical activity for people with Progressive Supranuclear Palsy (2020)2020 · PMID 31559853Open reference}

• Intensive inpatient rehabilitation may improve motor function in PSP patients^{7Performance of a Two-Week Rehabilitation Improves Motor Function in Inpatients with Progressive Supranuclear Palsy (2025)2025 · PMID 39851455Open reference}

• Task-specific training approaches show promise for functional improvement^{8Task-specific gait training for people with Parkinson disease (2015)2015 · PMID 26205625Open reference}

Mechanisms of benefit:

• Exercise promotes brain-derived neurotrophic factor (BDNF) release, potentially supporting neuronal survival

• Physical activity may enhance tau clearance through improved autophagy and glymphatic circulation

• Maintenance of muscle strength and cardiovascular fitness preserves functional independence

• Balance training reduces fall risk and associated morbidity

• Social engagement through group exercise programs may support cognitive and emotional health

Considerations Specific to Tauopathies

Rehabilitation in CBS and PSP differs from Parkinson’s disease in several important ways:

PSP-specific considerations:

• Axial rigidity affects trunk mobility, requiring targeted stretching

• Early and frequent falls (often within first year) necessitate aggressive fall prevention

• Vertical gaze palsy impairs navigation and reading

• Bradykinesis affects movement initiation

• Freezing of gait may be less responsive to visual cues than in PD

CBS-specific considerations:

• Asymmetric involvement requires compensatory strategies for the more-affected side

• Apraxia affects motor planning and execution

• Alien limb phenomenon creates unique functional challenges

• Cortical sensory loss affects proprioception

• Myoclonus may interfere with voluntary movement

Gait Training

Evidence and Rationale

Gait impairment is a cardinal feature of both CBS and PSP, significantly affecting independence and safety. Gait training in Atypical Parkinsonism targets the characteristic patterns of these conditions, including reduced stride length, shuffling gait, freezing episodes, and postural instability^{9Falls and freezing of gait in Parkinson's disease (2021)2021 · PMID 33751061Open reference}.

Research from Parkinson’s disease suggests that task-specific gait training can improve walking speed, stride length, and gait variability. While direct evidence in CBS/PSP is more limited, the principles are applicable with appropriate modifications for the unique features of these conditions^{10Treadmill training for patients with Parkinson disease (2017)2017 · PMID 27763449Open reference}.

Gait Training Interventions

Treadmill Training:

• Body weight-supported treadmill training for patients with significant gait impairment

• Start with 10-15 minute sessions at comfortable speed

• Progress by increasing duration before increasing speed

• Use harness for safety in patients with high fall risk

• Consider interval training (alternating high and low intensity)

Overground Gait Training:

• Verbal cueing for step length (“take longer steps”)

• Rhythmic auditory stimulation using metronome (120-140 BPM)

• Visual cues: laser pointer on walker or floor to step over -markers on ground to step across

• Walking between parallel bars for safety and confidence

Circuit Training:

• Gait stations including step-ups, obstacle negotiation, stair training

• Progressive difficulty as function improves

• Include forward, backward, and lateral movements

Aquatic Therapy:

• Water provides buoyancy reducing fall risk

• Allows resistance training for strength

• Warmer water (28-30°C) helps reduce rigidity

• Beneficial for patients who cannot tolerate land-based exercise

LSVT BIG Therapy

LSVT BIG is an intensive, amplitude-based movement therapy derived from the well-established LSVT LOUD speech therapy program. Originally developed for Parkinson’s disease, LSVT BIG has been adapted for the broader movement impairments seen in Atypical Parkinsonism^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}0.

Mechanism: The therapy works on the principle of “sensory recalibration” - training patients to perceive their movements as larger and more normal, which then carries over to automatic movement in daily activities. The intensive, repetitive nature of the program promotes neuroplastic change.

Protocol:

• 4 consecutive days per week for 4 weeks (16 sessions)

• 45-60 minutes per session

• Daily homework practice (30-45 minutes)

• 1-month and 3-month follow-up sessions to reinforce

Key Exercises:

1. Big Drills: Repeated maximum-amplitude movements

   • Arm raises (reaching up)

   • Arm reaches (side to side)

   • Big steps forward, backward, laterally

   • Big trunk rotations

2. Hierarchy Tasks: Progressive complexity

   • Sustained postures

   • Directional movements

   • Functional movements (sit-to-stand, walking)

   • Automatic movements (opening door, getting dressed)

3. Translating to Daily Activities:

   • Walking with bigger steps

   • Writing larger

   • Using bigger gestures

   • Opening containers more forcefully

Evidence:

• Significant improvements in UPDRS motor scores in PD patients^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}1

• Improved gait speed and stride length documented^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}2

• Benefits maintained at follow-up assessments

• Application to CBS/PSP shows promise but requires more study

Considerations for CBS/PSP:

• PSP patients may have reduced benefit due to axial rigidity

• CBS patients may benefit from focus on the more-affected side

• Cognitive impairment may affect learning and carryover

• May need modification for patients with significant dysphagia

Constraint-Induced Movement Therapy

Constraint-Induced Movement Therapy (CIMT) was originally developed for stroke rehabilitation but has applications in CBS where asymmetric involvement creates a “less-affected” and “more-affected” side^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}3.

Traditional CIMT Components:

1. Forced Use: Constraining the less-affected limb to force use of the more-affected limb

2. Shaping: Progressive task difficulty

3. Behavioral Transfer: Applying gains to daily life

Adaptations for CBS:

• Modified constraint (not full immobilization, but encouraging use of affected side)

• Shorter therapy sessions may be needed due to fatigue

• Focus on functional tasks relevant to individual patient

• Use of behavioral strategies to promote transfer

Evidence in CBS:

• Case studies suggest benefits for apraxia and motor function^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}4

• May help retrain motor planning circuits

• Benefits may be more pronounced in earlier disease stages

Contraindications:

• Severe cognitive impairment affecting learning

• Significant balance issues (constraining one limb increases fall risk)

• Severe apraxia limiting benefit

• Advanced disease with minimal movement in affected limb

Balance Therapy

Balance Impairment in CBS/PSP

Balance dysfunction in Atypical Parkinsonism results from multiple factors:

• Postural instability (PSP has earliest onset)

• Rigidity affecting trunk mobility

• Reduced proprioception (especially CBS)

• Cognitive impairment affecting dual-task performance

• Muscle weakness

• Sensory integration deficits

The Berg Balance Scale and Timed Up and Go test are recommended for assessing balance function and fall risk^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}5.

Balance Training Interventions

Sensory Integration Training:

• Balance exercises on varied surfaces (foam, rocker board, BOSU)

• Training with eyes open and closed to challenge sensory systems

• Progress from stable to unstable surfaces

• Include perturbed balance reactions

Weight-Shifting Exercises:

• Sit-to-stand transitions

• Stepping in multiple directions

• Weight shifting in standing with varying base of support

• Reaching tasks while maintaining balance

Dual-Task Training:

• Combining balance tasks with cognitive demands

• Counting backwards while walking

• Naming items while standing on foam

• Verbal fluency while performing balance tasks

• Critical for improving automaticity of balance

Functional Balance Activities:

• Medication effects

• Environmental hazards

Fall Prevention Strategies

Home Safety Assessment and Modifications:

Assistive Device Training:

• Walker selection for PSP (wheeled walker often better than standard walker)

• Gait belt for caregiver-assisted mobility

• Proper wheelchair positioning

• Canes may provide limited benefit in PSP due to freezing

Education:

• “Steering” rather than “stopping” when falling

• How to get up from floor

• When to ask for assistance

• Proper footwear selection

• Address orthostatic hypotension

Occupational Therapy Interventions

Apraxia Management

Apraxia, particularly limb apraxia, is a cardinal feature of CBS that significantly impacts activities of daily living^{2Effectiveness of allied health therapy in the symptomatic management of progressive supranuclear palsy: a systematic review (2016)2016 · PMID 27532657Open reference}8. Occupational therapy approaches include:

Compensatory Strategies:

• Task simplification: Breaking complex tasks into sequential steps

• Visual cueing: Pictures or written instructions for multi-step activities

• Environmental modification: Simplifying workspace, organizing items in order of use

• Consistent routines: Predictable patterns to reduce cognitive load

• Errorless learning: Minimizing errors during practice

Restorative Approaches:

• Task-specific training: Repeated practice of specific tasks in context

• Strategy training: Verbalization of steps before execution
