Beyond the Best Exercise: A Practical Framework for Personalized Rehabilitation in Parkinson’s Disease

Abstract

Exercise is established as an important adjunct in the treatment of Parkinson’s disease (PD). Yet the field has spent decades searching for a single “best” program – a quest that is fundamentally misguided. Instead, rehabilitation should be matched to each patient’s main impairments, goals, safety profile, cognitive status, and access to services. Four well-studied approaches – LSVT BIG, HiBalance, supervised therapeutic climbing, and community non-contact boxing – offer different mechanisms, expected outcomes, and practical demands. The core argument of this editorial is that optimal outcomes come from sequencing short, intensive blocks of targeted therapy followed by community‑based maintenance programs, guided by a small set of routinely collected clinical variables. Progress in PD rehabilitation will depend on patient‑centered pathways that integrate physiology‑driven treatment with sustainable community options, not on identifying a universal superior exercise.
LSVT BIG is an intensive, high‑repetition program focused on increasing movement amplitude and recalibrating sensorimotor perception. Randomized trials and meta‑analyses show improved motor scores and gait when the standard protocol is followed [1,2], with physiological studies supporting a proprioceptive recalibration mechanism [3]. These effects are most clearly reported in people with mild‑moderate PD who can tolerate an intensive, therapist‑led schedule [1,2]. The resource intensity and need for trained clinicians should be noted when LSVT BIG is recommended.
HiBalance targets balance subsystem deficits by training sensory integration, anticipatory postural adjustments, and dynamic stability. Short‑term gains in balance and gait have been reported in trials, and imaging studies suggest task‑related neuroplastic changes [4]. The magnitude of benefit has varied across studies, and non‑specific factors such as attention and group support influence outcomes in some trials [5,6]. HiBalance is therefore best used when postural instability or falls are the dominant clinical problems and when supervised, cognitively demanding training is feasible.
Supervised therapeutic climbing combines large‑amplitude limb and trunk movements, vertical loading, and complex visuomotor problem solving. Randomized trials report improvements in motor signs [7], with other controlled studies showing gains in posture and gait [8,9]. High adherence and strong patient engagement are documented in feasibility reports [10]. Notably, most climbing data originate from a single research group; independent confirmatory trials would strengthen generalizability. Proposed mechanisms include axial strengthening, transfer of vertical motor control to horizontal locomotion, and enhanced cognitive‑motor dual‑tasking. Climbing is most suitable where axial extension, posture correction, and sustained engagement are prioritized, and where safe infrastructure and trained supervision are available [7,8]. Attention to safety protocols and implementation costs is required [10].
Community non‑contact boxing programs have been widely adopted because they are engaging, socially reinforcing, and scalable. Trials and reviews report improvements in mood, motivation, and adherence, with modest gains in fitness and some motor outcomes [11,15] – though randomized trials show inconsistent effects on core PD motor signs [12,13]. The principal practical value of boxing is therefore often found in long‑term adherence and psychosocial benefit, which can support maintenance of gains achieved in targeted therapy blocks [14].
From this evidence, several practical principles emerge. Interventions should be matched to mechanism and goal: amplitude‑focused deficits → LSVT BIG; balance subsystem failure → HiBalance; axial/postural problems → supervised climbing where available; long‑term adherence and mood → community boxing when appropriate. Short, intensive blocks (typically 8–12 weeks) of targeted therapy are likely to produce focused gains that require ongoing maintenance. Community‑based or group activities are reasonable maintenance options when safety and access permit.
A critical gap in the original literature has been the absence of a simple, clinically usable decision tool. Table 1 summarizes a simple, hypothesis-generating decision framework based on five routinely collected variables: motor phenotype, fall history, cognitive status, patient goals, and access constraints. This framework is intended to support clinical reasoning and prospective validation, not to serve as a validated treatment algorithm.
