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.
BackgroundKnee osteoarthritis (KOA) is a leading cause of public disability. Neuromuscular function contributes to the development and/or progression of KOA. Whole body vibration (WBV) exercise improve the neuromuscular function of patients with neurological disorders and even that of older patients with limited exercise options. Therefore, WBV exercise may offer an efficient and alternative treatment for individuals with KOA. However, the effects of WBV training on the neuromuscular function of individuals with KOA remain unclear. Therefore, this study attempts to investigate the effect of a 12-week WBV exercise on the neuromuscular function of individuals with KOA.Methods/designWe will conduct a prospective, single-blind randomized controlled trial on 180 KOA patients. Participants will be randomly assigned to the WBV exercise, lower extremity resistance training, and health education groups. The WBV exercise group will participate in a 12-week WBV training. The lower extremity resistance training group will undergo a 12-week lower extremity resistance training of both lower limbs. The control group will receive health education for 12 weeks. After the intervention, the participants will be followed up for 3 months with no active intervention. Primary outcome measures will include anthropometric measurements, gait analysis during walking and stair climbing, muscle strength test of the knee and ankle, proprioception test of the knee and ankle, and neuromuscular response of the leg muscles. Secondary outcome measures will include self-reported pain and physical functional capacity, and physical performance measures. Furthermore, adverse events will be recorded and analyzed. If any participant withdraws from the trial, intention-to-treat analysis will be performed.DiscussionImportant features of this trial mainly include intervention setting, outcome measure selection, and study duration. This study is intended for estimating the effect of WBV intervention on neuromuscular control outcomes. Study results may provide evidence to support the beneficial effects of WBV exercise on the physical performance and neuromuscular control of individuals with KOA to fill the research gap on the efficacy of WBV.Trial registrationChinese Clinical Trial Registry, ID: ChiCTR-IOR-16009234.

Background Knee osteoarthritis (KOA) is one of the leading causes of global disability, which causes knee pain, stiffness and swelling. Impaired neuromuscular function may cause joint instability, alignment changes and knee stress, which leads to the progression of KOA. Whole-body vibration (WBV) training is considered to improve pain and functional mobility effectively. However, few studies have investigated the therapeutic effect of WBV on neuromuscular function in KOA. Material and methods A single-blinded, randomised, controlled trial was performed on 81 participants diagnosed with KOA. The participants were randomised into three groups: (1) WBV group, in which participants performed strength training (ST) with vibration exposure for 8 weeks; (2) ST group, in which participants performed ST without vibration for 8 weeks; and (3) health education (HE) group, in which participants received a HE for 8 weeks. The visual analogue scale for knee pain, isokinetic muscle strength test, proprioception test, Timed Up and Go test (TUG) and 6-min Walk Distance test (6MWD) were performed before and after the interventions. Results No significant difference was found on pain, proprioception, TUG and 6MWD. A significant interaction effect was found in isokinetic muscle strength between groups. Further analysis showed that compared with the HE group, the WBV group exhibited significantly greater improvement in isokinetic muscle strength (peak torque [PT] of extensors, p < 0.01, 95% CI = 0.11–0.33 Nm/kg; PT of flexors, p = 0.01, 95% CI = 0.02–0.19 Nm/kg; peak work [PW] of extensors, p < 0.01, 95% CI = 0.12–0.75 W/kg). In addition, compared with the ST group, the muscle strength of the WBV group (PT of extensors, p < 0.01, 95% CI = 0.10–0.32 Nm/kg; PW of extensors, p < 0.01, 95% CI = 0.09–0.71 W/kg) improved significantly. Conclusion Our findings suggested that adding WBV training to ST might benefit muscle strength around the knee joint in patients with KOA.
Background Knee osteoarthritis (KOA) is one of the leading causes of global disability which causes knee pain, stiffness, and swelling. Impaired neuromuscular function contributes to the development and/or progression of KOA. As a new modality to treat KOA, whole-body vibration (WBV) training is considered to improve pain and physical function effectively. However, limited numbers of studies were designed to investigate the effect of WBV on neuromuscular function in KOA.Methods 81 eligible participants with KOA were randomly allocated to WBV, strength training (ST) and health education (HE) groups. Each group of participants was encouraged to perform the WBV training, similar strength training and health education program, respectively. These supervised interventions were performed three times per week for 8 consecutive weeks. Neuromuscular function was measured with isokinetic muscle strength and proprioception. Physical function was assessed with Timed Up and Go (TUG) and 6-min Walk Distance tests. Results Physical function and neuromuscular function did not show significant difference between three groups (p > 0.05). However, post-hoc test showed that isokinetic knee muscle strength of WBV group (peak torque of extensor at 180°/s, peak torque of flexors at 180°/s, peak work of extensor at 180°/s, and peak work of flexor at 90°/s, all p < 0.05) increased significantly compared with HE group. Similarly, compared with ST group, muscle strength of WBV group (peak torque of extensor at 180°/s and peak work of extensor at 180°/s, p < 0.05) improved significantly. Conclusion The current study showed that the advantage of WBV training on muscle strength gain in patients with KOA compared with similar strength training without vibration and health education.Trial registration It was registered at Chinese Clinical Trial Registry a priori as a clinical trial (ID: ChiCTR-IOR-16009234).

Background Knee osteoarthritis (KOA) is among the most common osteoarthritis diseases that affect adults older than 65 years old. Impaired neuromuscular function contributes to the development and/or progression of KOA. As a new modality in strength training, whole-body vibration (WBV) training is considered in the management of KOA. However, the inconsistent results of previous studies dampened the enthusiasm for the clinical application of WBV.Methods Eligible participants with KOA were randomly allocated to WBV, strength training (ST) and health education (HE) groups. Finally, 57 participants completed the intervention and measurements. The participants in each group were encouraged to perform the WBV training, similar strength training or health education program. These supervised interventions were performed three times per week for 8 weeks. Physical function was assessed with Timed Up and Go (TUG) and 6-min Walk Distance tests. Neuromuscular function was measured with isokinetic muscle strength and proprioception. Results All variables of physical function and neuromuscular function failed to change significantly among three groups. However, compared with the baseline, the time of TUG and isokinetic muscle strength improved significantly only in WBV group. Conclusion WBV training has been recommended for strength training in elderly people and patients with musculoskeletal diseases. The 8-week WBV training under the protocol of our study was not superior to ST and HE. Hence, more clinical studies are required in the future to develop an optimal training protocol.
