Effects of balance and proprioceptive training on total hip and knee replacement rehabilitation: A systematic review and meta-analysis.

description

Abstract Backgound Balance and proprioceptive deficits are frequently persistent after total joint replacement, limiting functionality and involving altered movement patterns and difficulties in walking and maintaining postural control among patients. Research question The goal of this systematic review was to evaluate the short- and mid-term effects of proprioceptive and balance training for patients undergoing total knee and hip replacement. Methods This is a systematic review of literature. MEDLINE, Embase, Cochrane Library, PEDro, and Scopus were the databases searched. The review included randomized clinical trials in which the experimental groups underwent a training aimed at improving balance and proprioception, in addition to conventional care. The studies had to assess at least one of the following outcomes: self-reported functionality or balance (primary outcomes), knee function, pain, falls, or quality of life. Results Eight trials were included, involving 567 participants. The quantitative synthesis found a moderate to high significant effect of balance and proprioceptive trainings on self-reported functionality and balance after total knee replacement. The effects were maintained at mid-term in terms of balance alone. Conversely, preoperative training did not enhance outcomes after total hip arthroplasty. Significance The synthesis showed that, in clinical terms, balance trainings are a convenient complement to conventional physiotherapy care to produce an impact on balance and functionality after knee replacement. If outcomes such as improvement in pain, knee range of movement, or patient quality of life are to be promoted, it would be advisable to explore alternative proposals specifically targeting these goals. Further research is needed to confirm or discard the current evidence ultimately, predominantly in terms of the effects on the hips and those yielded by preoperative interventions.
