An Analysis Of Single And Multijoint Proprioception Of Lower Limb And Functional Mobility Among Patients With Parkinsons Disease

Parkinson’s is the second most common neurodegenerative disease. Parkinson’s disease is generally characterized by rigidity,tremor, bradykinesia, stooped posture, freezing of gait. Recent reports confirmthe presence of proprioception deficit in patients with Parkinson’sdisease.  Increased neuronal responsesand noise within the basal ganglia lead to reduced joint specificity inproprioceptive integration, impairing accurate movement and coordination. This disruption impairs the brain’s capacity to accuratelyintegrate sensory signals, causing diminished awareness of limb and trunkpositions, particularly affecting kinesthesia (the sense of movement). As thedisease progresses, these proprioceptive disturbances worsen, contributing toincreasingly impaired movement coordination, greater challenges in motorcontrol . Mostof the studies are done proprioception in a single joint rather than using themulti-joint. where, Single-joint proprioception tests assess sensory feedbackfrom specific joints but may not capture the broader impact on overall limbfunction. Whole-limb assessments offer a more comprehensive evaluation byconsidering how proprioceptive deficits affect the coordination and executionof movements involving multiple joints and muscles. This approach provides abetter understanding of how proprioceptive impairments influence functionalactivities. Therefore, we could like to test single joint and multi-jointproprioception of lower limb in patients with Parkinson’s disease and to assessthe presence of variation and its impact on functional mobility like gaitpatients with Parkinson’s.
