Stationary cycling exercise for knee osteoarthritis: A systematic review and meta-analysis

Abstract

Objective: To evaluate effects of stationary cycling exercise on pain, function and stiffness in individuals with knee osteoarthritis. Data sources: Systematic search conducted in seven databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, PEDro, and CNKI) from inception to September 2020. Review methods: Included studies were randomized-controlled trials involving stationary cycling exercise conducted on individuals with knee osteoarthritis. End-trial weighted mean difference (WMD) and 95% confidence interval (CI) were analyzed, and random-effects models were used. Methodological quality and risk bias were assessed by using the Physiotherapy Evidence Database scale and Cochrane Collaboration tool, respectively. Results: Eleven studies with 724 participants were found, of which the final meta-analysis was performed with eight. Compared to a control (no exercise), stationary cycling exercise resulted in reduced pain (WMD 12.86, 95% CI 6.90–18.81) and improved sport performance (WMD 8.06, 95% CI 0.92–15.20); although most of the meta-analysis results were statistically significant, improvements in stiffness (WMD 11.47, 95% CI 4.69–18.25), function (WMD 8.28, 95% CI 2.44–14.11), symptoms (WMD 4.15, 95% CI −1.87 to 10.18), daily living (WMD 6.43, 95% CI 3.19 to 9.66) and quality of life (WMD 0.99, 95% CI −4.27 to 6.25) for individuals with knee osteoarthritis were not greater than the minimal clinically important difference values for each of these outcome measures. Conclusions: Stationary cycling exercise relieves pain and improves sport function in individuals with knee osteoarthritis, but may not be as clinically effective for improving stiffness, daily activity, and quality of life.

Analysis of Clinical Efficacy of Clearing Heat and Dispelling Paralysis Soup in the Treatment of Osteoarthritis of the Knee Joint and Its Effect on Patients’ Motor Function

“…Inclusion criteria were as follows: (1) patients met the diagnostic criteria of osteoarthritis of the knee [ 4 ]; (2) patients met the syndromes of the Clinical Research Guidelines for New Chinese Medicines for Osteoarthrosis [ 5 ]; (3) morning stiffness of 30 min and less and frictional sounds when the joint was present; (4) X-ray showed joint space narrowing in weight-bearing position; and (5) informed and agreed to this study.…”

Is high intensity laser therapy more effective than other physical therapy modalities for treating knee osteoarthritis? A systematic review and network meta-analysis

“…Specifically, results here showed that gains on the stiffness sub-scale of the WOMAC were less than its relevant MCID value, despite being statistically significant. There are two possible explanations for this finding: (1) individuals treated with high intensity laser are always in a static state ( 37 ), while the improvement of stiffness typically requires range of motion training that involves repeated flexion and extension of the knee joint ( 44 , 49 , 50 ). Consequently, HILT does not bring about changes that promotes utilization of knee range of motion ( 30 ).…”

Test-Retest Reliability of Acoustic Emission Sensing of the Knee during Physical Tasks

“…These exercises were selected in order to capture straight-leg movements in both the sagittal (SLA) and frontal (SLF) planes, and knee flexion with (SLS) and without load (KL), thus facilitating the validation of the technique in different conditions and when different numbers of AE events are produced. Moreover, such exercises are frequently utilized in rehabilitation programmes in cases of post-injury, knee replacement, and osteoarthritis [ 29 , 30 , 31 ]. Knowing which exercises produce valid AE measures has the potential to improve not only AE diagnostic value, but also rehabilitation programmes by using AE to evaluate the patient’s progression in a more objective manner.…”
