Effects of strength exercise on the knee and ankle proprioception of individuals with knee osteoarthritis

Abstract

This study aims to investigate the effects of 8-week strength exercise on knee and ankle proprioception of individuals with knee osteoarthritis (KOA). Forty participants were randomly divided into control and strength exercise groups. Strength exercise group underwent squat training of three times a week for 8 weeks, while control group received an education programme. Threshold for detection of passive movement of knee and ankle joint was tested using an electrically driven movable frame. Between- and within-group differences were evaluated through repeated-measurement analysis of variance. After intervention, passive motion sense in knee flexion of participants in strength exercise group significantly improved (p = 0.033, 95% confidence interval of mean difference: 0.019-1.478) with significant difference between groups. No significant differences of passive motion senses were found in knee extension and ankle between strength exercise and control groups. Eight-week squat training significantly improves the motion sense of knee flexion in patients with KOA.

Effects of exercise on knee osteoarthritis: A systematic review

“…A significant improvement of passive motion sense in knee flexion was also detected (ES = 0.124). However, no significant differences of passive motion senses were found in knee extension and ankle (Lai et al, 2018).…”

“…From the retrieved studies, four (Braghin et al, 2018;Ha et al, 2018;Hunt et al, 2013;Karadağ et al, 2019) don't define age as an inclusion criteria. Considering the remaining studies, 40 years old was the minimum age required to participate (de Oliveira et al, 2012;DeVita et al, 2018;Dias et al, 2017;Henriksen et al, 2014;Huang et al, 2020;Imoto et al, 2012;Lai et al, 2018;Liu et al, 2019;Mazloum et al, 2018;Munukka et al, 2016;Shellington et al, 2019;Simão et al, 2012;Vincent et al, 2019;Wang et al, 2011), with one exception which allowed participants older than 18 to engage on it (Silva et al, 2015).…”

Exercise as a prescription for patients with various diseases

“…Compared with land-based cycling exercise, long-term regular swimming exercise has similar or even better effects on vascular function and inflammatory markers in patients with OA who tend to have a higher risk of cardiovascular disease 80 . In RE protocols, long-term strength exercise with gradually increasing intensity improved the motion sense of knee flexion 81 and lower extremity function in patients with knee OA 82 . For patients with hip OA, muscle power, walking speed, and cadence significantly increased only in the long-term, high-velocity group 83 .…”

Rehabilitation Effect of Exercise Therapy on Knee Osteoarthritis Evaluated by Computed Tomography Image under Optimized Reconstruction Algorithm

“…Some experts conducted research on the effect of exercise therapy on ADL in patients with end-stage knee osteoarthritis. e results showed that exercise therapy was very effective in improving patients' ADL even in the end- stage KOA, and it was worthy of promotion [20]. Experts also discussed the effect of exercise therapy on knee osteoarthritis and the effect on the VAS score.…”
