Low back pain is among the most common health problems seen in primary care. This study aimed to evaluate the effect of a corrective exercise program on GRF components, back pain, disability score, and muscle activities in back pain patients with pronated feet during walking.
What is the effect of corrective exercise program on gait kinetics, back pain, disability score, and muscle activities in back pain patients with pronated feet during walking?
Thirty-six older adults with both back pain and pronated feet volunteered to participate in this study. They were randomly divided into two equal groups (experimental and control groups). Kinetic and EMG data were recorded during both pre and posttest. Visual analog pain scale and Roland-Morris disability questionnaire were used to assess back pain and disability values, respectively.
In the experimental group but not in the control group, walking speed was significantly increased from pre to posttest (p = 0.001). The loading rate and free moment values were similar during both the pre and posttest (p > 0.05). In the experimental group but not in the control group, the disability score, back pain, tibialis anterior activity, and rectus abdominis activity were decreased during the posttest than that in the pretest (p < 0.001).
Higher walking speed, lower muscle activity and pain, lower disability score along with similar loading rate and free moments in the experimental group compared with the control group after the training protocol demonstrate the improvement of gait efficiency.
下背痛是初级保健中最常见的健康问题之一。本研究旨在评估矫正运动方案对跖屈足患者在行走时的地面反力、下背痛、残疾评分和肌肉活动的影响。
矫正运动方案对跖屈足患者在行走时的步态动力学、下背痛、残疾评分和肌肉活动有什么影响？
36 名既有下背痛又有跖屈足的老年人自愿参加了这项研究。他们被随机分为两组（实验组和对照组）。在预测试和后测试期间记录了动力学和肌电图数据。使用视觉模拟疼痛量表和 Roland-Morris 残疾问卷分别评估下背痛和残疾值。
在实验组，但不在对照组中，行走速度从预测试到后测试显著增加（p=0.001）。在预测试和后测试期间，加载率和自由力矩值相似（p>0.05）。在实验组，但不在对照组中，后测试时的残疾评分、下背痛、胫骨前肌活动和腹直肌活动均低于前测试（p<0.001）。
与对照组相比，实验组在训练后行走速度更高、肌肉活动和疼痛更低、残疾评分更低，而加载率和自由力矩相似，这表明步态效率得到了提高。
