The effects of resistance exercise in patients with knee osteoarthritis: a systematic review and meta-analysis

Objective: to evaluate the impact of a three-month resistance exercise program on the pain and functionality of elderly patients with knee osteoarthritis from the city of Santa Cruz, Rio Grande do Norte. Method: a quasi-experimental study was performed with 13 elderly patients diagnosed with knee osteoarthritis, who underwent a resistance training program twice a week for 12 weeks. Pain, muscle strength, functionality, quality of life and patient satisfaction were evaluated using the following instruments: the visual analog scale, one repetition maximum testing, the Western Ontario and McMaster Universities Osteoarthritis Index, the Timed Up and Go Test, the 6-minute walk Test, the Short Form (36) Health Survey and the Likert scale. The paired T-test and ANOVA for repeated measures were used for statistical analysis. Results: the mean age of the patients was 62.0 (±10.0) years. At the end of the study, the pain, muscle strength, functional status and some areas of quality of life of the elderly had improved. Conclusion: resistance exercises were an effective and safe method of improving the pain, muscle strength, functionality and quality of life of the population studied. The elderly should be encouraged to perform supervised strength training therapy.

“…In this sense, countless studies and reviews involving therapeutic exercise and resistance exercise have demonstrated success in the reduction of pain in these patients, 11,12,14,[26][27][28][29] which can cause a natural increase in the level of physical activity, helping control weight and increasing physical capacity.…”

Comparison of the effects of resistance exercise versus kinesiotherapy in knee osteoarthritis

Increased life expectancy in several populations makes osteoarthritis (OA) an important public health issue, as it is a very prevalent chronic disease and leading cause of pain and disability among adults and elderly. Objective: The aim of this study was to compare pain, mobility, functional capacity, and strength of patients with knee osteoarthritis submitted to two different interventions: resistance exercise (REG) and kinesiotherapy (KIG). Methods: This was a prospective randomized single blind clinical trial, which involved the participation of 30 adults of both sexes diagnosed with knee OA. Volunteers were evaluated for pain, stiffness, function, functional mobility, and strength by a blinded evaluator before and after the interventions. Through a simple drawing, participants were randomly assigned to one of the two intervention groups, and underwent 15 twice-weekly treatment sessions, lasting 30 minutes each. Results: Both interventions promoted significant improvements in all variables, and there were no reports of any adverse effects throughout the research. Conclusion: Both resistance exercise and kinesiotherapy are effective in improving pain, stiffness, function, functional mobility, and strength in patients with knee OA.

“…Resistance training is an exercise intervention that has been utilised to decrease symptoms, impairment, and improve function in individuals with OA at the knee and hip [9, 10]. Several studies have demonstrated its effectiveness and this treatment modality is included in the American College of Rheumatology 2012 treatment guidelines for knee and hip OA, but not for hand OA [11].…”

The effects of resistance training on muscle strength, joint pain, and hand function in individuals with hand osteoarthritis: a systematic review and meta-analysis

BackgroundHand osteoarthritis is a common condition characterised by joint pain and muscle weakness. These factors are thought to contribute to ongoing disability. Some evidence exists that resistance training decreases pain, improves muscle strength, and enhances function in people with knee and hip osteoarthritis. However, there is currently a lack of consensus regarding its effectiveness in people with hand osteoarthritis. Therefore, the aim of this systematic review and meta-analysis was to establish whether resistance training in people with hand osteoarthritis increases grip strength, decreases joint pain, and improves hand function.MethodsSeven databases were searched from 1975 until July 1, 2016. Randomised controlled trials were included. The Cochrane Risk of Bias Tool was used to assess studies’ methodological quality. The Grade of Recommendations Assessment, Development, and Evaluation system was adopted to rate overall quality of evidence. Suitable studies were pooled using a random-effects meta-analysis.ResultsFive studies were included with a total of 350 participants. The majority of the training programs did not meet recommended intensity, frequency, or progression criteria for muscle strengthening. There was moderate-quality evidence that resistance training does not improve grip strength (mean difference = 1.35; 95% confidence interval (CI) = –0.84, 3.54; I 2 = 50%; p = 0.23 ). Low-quality evidence showed significant improvements in joint pain (standardised mean difference (SMD) = –0.23; 95% CI = –0.42, –0.04; I 2 = 0%; p = 0.02) which were not clinically relevant. Low-quality evidence demonstrated no improvements in hand function following resistance training (SMD = –0.1; 95% CI = –0.33, 0.13; I 2 = 28%; p = 0.39).ConclusionThere is no evidence that resistance training has a significant effect on grip strength or hand function in people with hand osteoarthritis. Low-quality evidence suggests it has a small, clinically unimportant pain-relieving effect. Future studies should investigate resistance training regimes with adequate intensity, frequency, and progressions to achieve gains in muscle strength.Electronic supplementary materialThe online version of this article (doi:10.1186/s13075-017-1348-3) contains supplementary material, which is available to authorized users.
