Despite the knowledge about the link between balance and core stability, studies investigating the importance of core stability exercise and their impact on balance are limited. Therefore, the authors aimed to explore whether core strengthening exercises in combination with hip exercises, when compared to a hip exercise programme and a control group, led to better improvements in balance in patients with hip osteoarthritis. In order to meet these aims, this paper reports the outcomes of a randomized, three-arm parallel, assessor-blinded, controlled clinical trial. Fifty-one participants awaiting a total hip replacement were recruited into this study. All patients were randomly allocated to a control, hip exercise group and hip and core exercise group. All participants were assessed for core muscle strength using a pressure biofeedback unit and balance using the four-stage balance test. The control group had no intervention. A 12-week hip and core exercise programme did not result in improvements over and above the hip exercise group in balance scores. However an improvement in core stability was noted for the hip and core exercise group (P = 0.001). Therefore, this study concluded that both exercise groups are resulted in improved balance with the core and hip exercise group noted to have added improvements, but the difference between the groups was not statistically significant.","PeriodicalId":14301,"journal":{"name":"International Journal of Rehabilitation Research","volume":"46 3","pages":"252-257"},"PeriodicalIF":1.7,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10280249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty-one healthy participants were asked to perform 25 trials of a reaching task in immersive VR with and without visual feedback of their hand. They were instructed to place, as accurately and as fast as possible, a controller held in their non-dominant hand in the centre of a virtual red cube of 3 cm side length. For each trial, the end-point error (distance between the tip of the controller and the centre of the cube), a coefficient of linearity (CL), the movement time (MT), and the spectral arc length of the velocity signal (SPARC), which is a movement smoothness index, were calculated. Multivariate analyses of variance were conducted to assess the influence of visual feedback, age and trial repetition on the average end-point error, SPARC, CL and MT, and their time course throughout the 25 trials. Providing visual feedback of the hand reduced average end-point error ( P  < 0.001) and MT ( P  = 0.044), improved SPARC ( P  < 0.001) but did not affect CL ( P  = 0.07).
