Effectiveness and current recommendation of manual therapy on hip osteoarthritis. An overview

Introduction: Osteoarthritis (OA) is the most common joint disease, increases with age and it is estimated that in those over 60 years of age more than 80 % have OA in at least one joint. Currently, the evidence regarding manual therapy (MT) in hip OA has had unclear results. Therefore, the main objective of this study is to determine the effectiveness and recommendation of MT in the hip OA. And secondary objectives, (I) review the existing literature on the intervention of MT in hip OA, (II) calculate the effectiveness of MT techniques in hip OA and (III) determine if there are benefits after the MT intervention in hip OA. Methods: A systematic search was carried out in electronic databases, in order to compile the available literature between the years 2000 and 2019, taking as reference the PRISMA statement for systematic reviews. Letters to the editor, bibliographic reviews and gray literature were excluded. Results: After reviewing 30 articles, we included 7 RS and 14 RCTs. 7 RCTs measured pain intensity of OA in response to MT vs. a control group. 4 RCTs measuring pain intensity in hip OA using MT + exercises Seven RCTs measured function in subjects with hip OA in response to MT vs. CG. Two RCTs evaluated the effects of MT + Ex on function. Discussion: Although the results were in favor of manual therapy, compared to the control group, these were not statistically significant, so we propose to carry out new primary studies to eliminate some biases in program execution and improve intervention in both groups.
