Effect of proprioceptive training compared to other interventions for upper limb deficits in people with Parkinson's disease: A systematic review and meta-analysis of randomised controlled trials.

Findings regarding the effect of proprioceptive training on hand dexterity in the short-term are inconclusive. The small sample size likely limited effect detection. Future large RCTs should compare proprioceptive training with no intervention and perform comprehensive biomechanical analysis to gain a clearer idea of its effects. Incorporating longer-duration proprioceptive training programs is also recommended to investigate long-lasting effects.
