The aim of this study was to investigate the short- and intermediate-term effects of a flexible spinal orthosis on postural control, neuromuscular performance, physical activity, fall-related self-efficacy, quality of life and perceived pain in osteoporosis.
72 postmenopausal osteoporotic women with and without vertebral fractures were randomly assigned to receive either a spinal orthosis (Thämert Osteo-Med) for 6 months or to a waiting list control. The following outcome measures were assessed at baseline and at 3- and 6-months follow-up: postural sway, maximum isometric voluntary force of the back extensors and quadriceps femoris, physical activity (IPAQ), fall-related self-efficacy (FES-I), health-related quality of life (QUALEFFO-41) and perceived pain.
For the orthosis group, repeated measures ANOVA revealed a significant increase in trunk extensors muscle strength at 3- and 6-months follow-up and self-perceived pain reduction within the 5th month of evaluation in comparison to the control group. The remaining parameters showed non-significant changes while wearing the orthosis.
The application of the orthosis introduces neuromuscular trunk strength improvement in conjunction with pain reduction in women with spinal osteoporosis. Future research should evaluate long-term effects on habitual physical activity, fall-related fracture risk and health-related quality of life.
本研究旨在调查一种柔性脊柱矫形器对骨质疏松症患者姿势控制、神经肌肉功能、身体活动、跌倒相关自我效能感、生活质量和疼痛感知的短期及中期影响。
72名有或无椎体骨折的绝经后骨质疏松症女性被随机分为两组，一组接受脊柱矫形器（Thämert Osteo-Med）治疗6个月，另一组作为等待名单对照组。在基线、3个月和6个月随访时评估以下结果指标：姿势摆动、背部伸肌和股四头肌的最大等长随意力、身体活动（国际体力活动问卷）、跌倒相关自我效能感（跌倒效能感量表-国际版）、健康相关生活质量（QUALEFFO-41）和疼痛感知。
对于矫形器组，重复测量方差分析显示，与对照组相比，在3个月和6个月随访时，躯干伸肌力量显著增加，且在评估的第5个月内自我感知疼痛减轻。佩戴矫形器时，其余参数显示无显著变化。
矫形器的应用可改善脊柱骨质疏松症女性的神经肌肉躯干力量并减轻疼痛。未来的研究应评估其对习惯性身体活动、跌倒相关骨折风险和健康相关生活质量的长期影响。
