Adding a local vibration system to a semirigid thoracolumbar orthosis may improve the effectiveness of the orthosis on muscle function in seniors with age-related hyperkyphosis.
This study was a parallel two-arm randomized controlled trial. Eighteen seniors with age-related hyperkyphosis were randomized into the conventional semi-rigid thoracolumbar orthosis group (control group) or the conventional semi-rigid thoracolumbar orthosis plus local vibration (intervention group); from June 10, 2023 to December 21, 2023. The outcomes included the thoracic kyphosis angle (TKA), parameters of isometric, isotonic, and isokinetic trunk muscle function; the SF-36 questionnaire; the 2-min walk test (2 MW); the 10-m walk test (10 MW); and the timed up and go test (TUG). Dependent variables were compared between groups across three time points using mixed-model ANOVA. One-way repeated-measures ANOVA was applied for significant time interactions.
After 6 weeks, the TKA significantly improved ( = 0.001) in both groups and showed more reduction in the intervention group ( = 0.001). The average torque of the trunk isometric extensor ( = 0.005) and flexor ( = 0.027) significantly improved in both groups. The average power of the isotonic extensors ( = 0.018) and flexors ( = 0.024) improved significantly. Isokinetic work for extensors ( = 0.030), flexors ( = 0.021) and average power ( = 0.017) increased.
TKA significantly improved after 6 weeks of intervention. This improvement was significantly more in the intervention group. Adding local vibration may improve the isotonic and isokinetic torques and time parameters but not the isometric parameters of the trunk muscles.
在半刚性胸腰椎矫形器上添加局部振动系统，可能会提高该矫形器对患有年龄相关性脊柱后凸的老年人肌肉功能的疗效。
本研究为平行双臂随机对照试验。18名患有年龄相关性脊柱后凸的老年人被随机分为传统半刚性胸腰椎矫形器组（对照组）或传统半刚性胸腰椎矫形器加局部振动组（干预组）；时间为2023年6月10日至2023年12月21日。结局指标包括胸椎后凸角（TKA）、等长、等张和等速躯干肌肉功能参数；SF-36问卷；2分钟步行试验（2MW）；10米步行试验（10MW）；以及计时起立行走试验（TUG）。使用混合模型方差分析在三个时间点比较组间的因变量。对于显著的时间交互作用，应用单向重复测量方差分析。
6周后，两组的TKA均显著改善（P = 0.001），且干预组的改善更明显（P = 0.001）。两组的躯干等长伸肌（P = 0.005）和屈肌（P = 0.027）平均扭矩均显著改善。等张伸肌（P = 0.018）和屈肌（P = 0.024）的平均功率显著提高。伸肌（P = 0.030）、屈肌（P = 0.021）的等速功和平均功率（P = 0.017）增加。
干预6周后TKA显著改善。干预组的这种改善更为显著。添加局部振动可能会改善躯干肌肉的等张和等速扭矩及时间参数，但对等长参数无影响。
