Rehabilitation and multidisciplinary management form the cornerstone of care for patients with Progressive Supranuclear Palsy (PSP), as pharmacurgical treatments provide limited symptomatic benefit[@fox2011]. Unlike Parkinson's disease where dopaminergic medications offer substantial relief, PSP patients require comprehensive rehabilitative strategies to maintain function, prevent complications, and optimize quality of life[@bhattacharya2022]. The progressive nature of PSP, with its characteristic vertical supranuclear gaze palsy, axial rigidity, and early postural instability, demands a proactive and integrated approach to rehabilitation that addresses motor, cognitive, and speech domains simultaneously[@litvan1998].
This page synthesizes the evidence base for rehabilitation interventions in PSP, covering physical therapy approaches for gait and balance, occupational therapy for activities of daily living, speech and language therapy for dysarthria and dysphagia, and multidisciplinary care coordination. The goal is to provide clinicians and caregivers with evidence-informed strategies to maximize functional independence and preserve quality of life throughout the disease course.

Balance training in PSP requires specialized approaches that account for the unique postural instability phenotype characteristic of the disorder. Unlike Parkinson's disease where balance deficits respond to cueing strategies and medication adjustments, PSP balance impairment stems from midbrain and brainstem degeneration that is less amenable to compensatory strategies[@williams2005]. Evidence from prospective cohort studies demonstrates that individualized balance training programs can modestly slow the progression of postural instability, particularly when initiated early in the disease course[@nocera2016].
The Berg Balance Scale and the Tinetti Assessment Tool are validated instruments for quantifying balance deficits and tracking progression in PSP[@berg1999]. Physical therapy interventions typically include weight-shifting exercises, reaching tasks in standing, and perturbation-based training designed to improve reactive balance responses[@shumwaycook2000]. However, therapists must exercise caution with high-intensity balance challenges, as PSP patients are at elevated risk for falls and fall-related injuries due to the combination of postural instability, visual impairment from vertical gaze palsy, and cognitive-executive dysfunction[@stolze2001].
Gait rehabilitation in PSP focuses on compensating for the characteristic magnetic gait, shuffling, and freezing of gait that emerges early in the disease course[@factor2003]. Visual cueing techniques, such as floor markers or laser-guided walking, can help overcome the movement blocking that characterizes PSP gait[@morris2000]. Treadmill training with body weight support has shown modest benefits in selected patients, though evidence remains limited to small case series[@protas2005].
Assistive devices require careful consideration in PSP. While canes and walkers provide mechanical stability, they may paradoxically increase fall risk in patients with significant cognitive impairment or those who cannot reliably manipulate the device[@stack2008]. Environmental modifications, including removal of tripping hazards, installation of grab bars, and optimization of lighting, form an essential component of gait rehabilitation[@gillespie2009].
Aerobic exercise and resistance training appear to provide general health benefits in PSP, though specific disease-modifying effects remain unproven[@schenkman2017]. Current recommendations favor low-impact activities such as swimming, cycling on stationary bikes, and gentle yoga, with intensity tailored to individual functional capacity[@postuma2015]. The progressive nature of PSP means that exercise programs require ongoing adaptation as functional abilities decline.
Occupational therapy addresses the progressive loss of independence in activities of daily living (ADLs) that characterizes PSP[@brown1998]. The Barthel Index and Functional Independence Measure provide standardized assessments of ADL performance and guide intervention planning[@mahoney1965]. Common targets include dressing, grooming, toileting, and feeding, with adaptive strategies and assistive devices employed to maintain function[@jnsson2003].
Environmental modifications form a central component of occupational therapy intervention. Home assessments identify barriers to safe function, and recommendations may include wheelchair accessible bathrooms, stair glides, and adaptive kitchen equipment[@gitlin2004]. Caregiver education ensures that modifications are implemented consistently and that family members understand the rationale for adaptive strategies[@corallo2019].
The frontal executive dysfunction prominent in PSP requires specialized occupational therapy approaches that address planning, sequencing, and problem-solving deficits[@pillon1995]. Strategy training, including external memory aids, structured routines, and visual prompts, can partially compensate for executive dysfunction[@zgaljardic2007]. However, the progressive nature of PSP means that cognitive interventions require ongoing adaptation as deficits worsen.
Hypokinetic-spastic dysarthria is nearly universal in PSP, resulting from the combined effects of bulbar rigidity, bradykinesia, and respiratory dysfunction[@darley1975]. Speech therapy interventions focus on improving respiratory support, articulation clarity, and speech rate control[@ramig2007]. Lee Silverman Voice Treatment (LSVT) LOUD, originally developed for Parkinson's disease, has been adapted for PSP with modest benefits in voice intensity and clarity[@sapir2010].
Augmentative and alternative communication (AAC) devices become necessary as dysarthria progresses. Low-tech options include alphabet boards and picture cards, while high-tech solutions include tablet-based speech-generating devices[@beukelman2012]. Early introduction of AAC is recommended to allow patients to participate in decisions regarding communication methods before cognitive impairment limits their ability to learn new systems[@friedoken2007].
Dysphagia affects the majority of PSP patients and represents a significant source of morbidity and mortality[@mller2001]. Videofluoroscopic swallowing studies characterize the specific swallowing deficits, which typically include delayed pharyngeal transit, reduced hyolaryngeal excursion, and impaired cricopharyngeal opening[@logemann1998]. Compensatory strategies such as head posturing, dietary modification, and swallowing maneuvers can reduce aspiration risk[@bathgate2015].
Falls represent a major source of morbidity in PSP, with retrospective studies indicating that over 70% of patients experience at least one fall per year, and over 40% experience recurrent falls[@wielinski2005]. Fall risk factors include the characteristic postural instability, visual impairment from vertical gaze palsy, cognitive-executive dysfunction, and environmental hazards[@lamb2008]. Multifactorial interventions addressing these risk factors show modest benefits in reducing fall frequency[@gillespie2009a].
Hip protectors show mixed evidence in PSP, with some studies suggesting benefit in reducing fracture risk while others indicate poor compliance limits effectiveness[@gillespie2007]. Home safety assessments and modification form an essential component of fall prevention programs[@clemson2008].
Comprehensive PSP management requires coordination among neurologists, physical therapists, occupational therapists, speech-language pathologists, social workers, and primary care providers[@volonte2002]. The progressive nature of PSP and the multi-domain deficits necessitate regular reassessment and adjustment of treatment plans[@van2000]. Palliative care consultation becomes appropriate as PSP advances, focusing on symptom management, caregiver support, and advance care planning[@goy2008].
Recent advances in PSP rehabilitation have focused on technology-assisted interventions, tele-health delivery, and objective monitoring using wearable devices.
Martinez et al. (2024) conducted a randomized controlled trial of intensive balance training in PSP, demonstrating significant improvements in Berg Balance Scale scores compared to standard physical therapy[@martinez2024]. Their protocol emphasized perturbation-based training tailored to PSP-specific postural deficits.

These recent advances have several implications for rehabilitation practice:
