Cross-sectional study.
The aim of this study was to compare trunk muscle activation during anterior and lateral reach in athletic and sedentary individuals with spinal cord injury (SCI) and able-bodied people.
University Hospital-UNICAMP, Campinas, Brazil.
Individuals with complete traumatic SCI and thoracic neurological level were separated into two groups: sedentary (SSCI: n=10) and physically active (PASCI: n=10). The control group (C: n=10) without SCI was assessed. Trunk muscle activation was recorded during reach and grasp tasks. The significant level was set at P<0.05.
The control group showed a highest mean activation for left longissimus muscle during all activities (P<0.05). The PASCI group presented significant highest activation for left iliocostalis muscles during all activities, except in the anterior reach task of 90% maximum reach (anterior reach (AR) 75: P=0.02; right lateral reach (RLR) 75: P=0.03; RLR90: P=0.01). The SSCI group presented highest activation for the left iliocostalis during the right lateral reach task of 75 and 90% maximum reach and right iliocostalis during the anterior reach task of 75% maximum reach (AR75: P=0.007; RLR75: P=0.02; RLR90: P=0.03). A different pattern of muscle activation between the control group and the groups with SCI was observed.
Our results indicated that sports practice did not affect the trunk muscle activation in people with paraplegia. However, the pattern muscle activation in individuals with SCI is different compared with people without SCI during anterior reach tasks.
横断面研究。
本研究旨在比较脊髓损伤（SCI）的运动员和久坐不动者以及健全人在前伸和侧伸过程中躯干肌肉的激活情况。
巴西坎皮纳斯大学医院-UNICAMP。
将完全性创伤性SCI且神经损伤平面在胸段的个体分为两组：久坐不动组（SSCI：n = 10）和体育活动组（PASCI：n = 10）。对无SCI的对照组（C：n = 10）进行评估。在伸手和抓握任务期间记录躯干肌肉的激活情况。显著性水平设定为P<0.05。
对照组在所有活动中左侧最长肌的平均激活程度最高（P<0.05）。PASCI组在所有活动中左侧髂肋肌的激活程度显著最高，但在最大伸展度90%的前伸任务中除外（前伸（AR）75：P = 0.02；右侧侧伸（RLR）75：P = 0.03；RLR90：P = 0.01）。SSCI组在最大伸展度75%和90%的右侧侧伸任务中左侧髂肋肌的激活程度最高，在最大伸展度75%的前伸任务中右侧髂肋肌的激活程度最高（AR75：P = 0.007；RLR75：P = 0.02；RLR90：P = 0.03）。观察到对照组与SCI组之间肌肉激活模式不同。
我们的结果表明，体育锻炼并未影响截瘫患者的躯干肌肉激活。然而，在进行前伸任务时，SCI个体的肌肉激活模式与无SCI个体不同。
