Vertebral fractures are the most common clinical manifestations of osteoporosis. Vertebral fractures and reduced back extensor strength can result in hyperkyphosis. Hyperkyphosis is associated with diminished daily functioning and an increased risk of falling. Improvements in back extensor strength can result in decreased kyphosis and thus a decreased risk of falls and fractures.
The aim was to examine the effects of an active spinal orthosis - Spinomed III - on back extensor strength, back pain and physical functioning in women with osteoporotic vertebral fractures.
Experimental follow-up.
The women used the active spinal orthosis for 3 months. Outcomes were changes in isometric back extensor strength, changes in back pain and changes in physical functioning.
A total of 13 women were included in the trial. Wearing the orthosis during a 3-month period was associated with an increase in back extensor strength of 50% (p = 0.01). The study demonstrated a 33% reduction in back pain and a 6.5-point improvement in physical functioning. The differences in pain and physical functioning were borderline significant.
The women demonstrated a clinically relevant improvement in the back extensor strength. The differences in pain and physical functioning were clinically relevant and borderline significant.
The results imply that Spinomed III could be recommended for women with vertebral fractures as a supplement to traditional back strengthening exercises. It is essential that the orthosis is adjusted correctly and that there is an individual programme concerning the amount of time the orthosis has to be worn every day.
椎体骨折是骨质疏松症最常见的临床表现。椎体骨折和背部伸肌力量减弱可导致脊柱后凸加剧。脊柱后凸加剧与日常功能减退及跌倒风险增加有关。背部伸肌力量的改善可减轻脊柱后凸程度，从而降低跌倒和骨折风险。
研究一种主动式脊柱矫形器——Spinomed III对骨质疏松性椎体骨折女性的背部伸肌力量、背痛及身体功能的影响。
实验性随访研究。
这些女性使用主动式脊柱矫形器3个月。观察指标为等长背部伸肌力量的变化、背痛的变化及身体功能的变化。
共有13名女性纳入该试验。在3个月期间佩戴该矫形器使背部伸肌力量增加了50%（p = 0.01）。研究显示背痛减轻了33%，身体功能改善了6.5分。疼痛和身体功能方面的差异接近显著。
这些女性的背部伸肌力量在临床上有显著改善。疼痛和身体功能方面的差异具有临床相关性且接近显著。
结果表明，Spinomed III可推荐给椎体骨折女性，作为传统背部强化锻炼的补充。正确调整矫形器并制定关于每天佩戴矫形器时长的个性化方案至关重要。
