Hallux valgus (HV), which is one of the most common musculoskeletal abnormalities of the foot, is defined as the medial deviation of the first metatarsophalangeal (MTP) joint and the lateral deviation of the great toe.
This study aimed to investigate the immediate effects of a manual stretching maneuver (MSM) in subjects with HV.
Twenty-five subjects with a total of 25 feet with mild HV participated in the study. The MSM, consisting of global stretching of the foot and toes, traction of the hallux, local stretching for hallux, and mobilization of the MTP joint of the hallux. The HV angle between the line of the first metatarsal bone and the proximal phalanx were measured using a goniometer. The cross-sectional area (CSA) of the AbdH was measured using ultrasonography. Zebris FDM was used to measure the static plantar pressure and the movement of the center of pressure (COP) standing on one foot. The dependent variables before and after treatment were compared using paired t-tests. The significance level was set at .05.
The HV angle significantly decreased from 20.25° to 16.96°. The CSA of the AbdH significantly increased from 14.00 mm to 16.11 mm. The peak pressure on the hallux and 1st, 2nd and 3rd metatarsals increased significantly. The contact area and total pressure on the hallux significantly increased. The sway of the COP on the length of the minor axis and velocity significantly decreased.
This study suggests that the MSM can be effective in decreasing the HV angle in subjects with mild HV. However, further longitudinal clinical studies are required to investigate the long-term effects of the MSM in subjects with HV.
拇外翻（HV）是足部最常见的骨骼肌肉异常之一，定义为第一跖趾（MTP）关节内侧偏斜和大脚趾外侧偏斜。
本研究旨在探讨手法拉伸（MSM）对轻度 HV 患者的即刻影响。
25 名共 25 只轻度 HV 患者参与了本研究。MSM 包括足部和脚趾的整体拉伸、大脚趾牵引、大脚趾局部拉伸和大脚趾 MTP 关节的松动。使用量角器测量第一跖骨线和近节趾骨之间的 HV 角度。使用超声测量 AbdH 的横截面积（CSA）。Zebris FDM 用于测量单脚站立时的静态足底压力和中心压力（COP）的移动。使用配对 t 检验比较治疗前后的因变量。显著性水平设为.05。
HV 角度从 20.25°显著降低至 16.96°。AbdH 的 CSA 从 14.00mm 显著增加至 16.11mm。大脚趾和第 1、2、3 跖骨的峰值压力显著增加。大脚趾的接触面积和总压力显著增加。COPe 的摆动幅度在短轴和速度上显著减小。
本研究表明，MSM 可有效降低轻度 HV 患者的 HV 角度。然而，需要进一步的纵向临床研究来探讨 MSM 对 HV 患者的长期影响。
