Effect of torso training on unstable surface on lower limb motor function in patients with incomplete spinal cord injury

To investigate the effect of torso training on unstable surface on lower limb motor function in patients with incomplete spinal cord injury.A total of 80 patients with incomplete spinal cord injury caused by thoracolumbar fracture admitted in Ningbo Yinzhou No.2 Hospital from April 2020 to December 2021 were randomly divided into control group and study group, with 40 cases in each group. In addition to routine training, the control group received torso training on stable surface and the study group received torso training on unstable surface. The gait, lower limb muscle strength, balance function, lower limb function, mobility and nerve function of the two groups were compared.After treatment, the stride length, stride frequency and comfortable walking speed improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05). The muscle strength of quadriceps femoris, gluteus maximus, hamstring, anterior tibialis and gastrocnemius were improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05); the total trajectories of static eye opening and static eye closing gravity center movement in the two groups were significantly shorter (all P<0.05), and the improvements in the study group were more significant (all P<0.05). The dynamic stability limit range and the American Spinal Injury Association (ASIA) lower extremity motor score, Berg balance scale, modified Barthel index scale in the two groups were significantly higher (all P<0.05), and these scores in study group were significantly higher than those in the control group (all P<0.05). Both groups showed a significant improvement in ASIA grade (all P<0.05), and the improvement in the study group was significantly better (P<0.05).Torso training on unstable surface can effectively improve the gait and lower limb muscle strength of patients with incomplete spinal cord injury and improve the lower limb motor function.目的: 分析不稳定表面躯干训练对不完全性脊髓损伤患者下肢运动功能的影响。方法: 选取宁波市鄞州区第二医院2020年4月至2021年12月胸腰段骨折所致不完全性脊髓损伤患者80例，随机分为对照组和观察组，各40例。除常规训练外，对照组进行稳定表面躯干训练，观察组进行不稳定表面躯干训练。比较两组的步态、下肢肌力、平衡功能、下肢功能、活动能力及神经功能。结果: 两组跨步长、步频、舒适步速较治疗前均明显增加（均P<0.05），且观察组优于对照组（均P<0.05）；股四头肌、臀大肌、腘绳肌、胫前肌、腓肠肌肌力水平较治疗前均明显升高（均P<0.05），且观察组高于对照组（均P<0.05）；静态睁眼重心移动总轨迹长、静态闭眼重心移动总轨迹长较治疗前均明显缩短（均P<0.05），且观察组短于对照组（均P<0.05）；动态稳定极限范围及美国脊髓损伤学会（ASIA）下肢运动评分、Berg平衡量表、改良Barthel指数量表评分较治疗前均明显升高（均P<0.05），且观察组高于对照组（均P<0.05）；ASIA分级较治疗前明显改善（均P<0.05），且观察组改善情况优于对照组（P<0.05）。结论: 不稳定表面躯干训练可有效改善不完全性脊髓损伤患者的步态及下肢肌力，提高患者的下肢运动功能。.
