To determine whether a 10-week supervised hip flexor stretching program in healthy elderly subjects would increase peak hip extension, stride length and gait speed and reduce anterior pelvic tilt during walking.
A double-blinded, randomized, controlled trial.
Pre- and posttreatment assessments were performed in a gait laboratory, whereas stretching exercises were performed outside of the laboratory, usually in the subject's home.
Eighty-two healthy elderly individuals, with 39 subjects in the control group and 43 subjects in the treatment group.
The treatment group completed a 10-week, twice-daily hip flexor stretching program, which was supervised twice weekly by a rehabilitation clinician. The control group completed a 10-week shoulder abductor stretching program.
Passive hip extension range of motion, dynamic peak hip extension, peak anterior pelvic tilt, stride length, and gait speed during walking.
The treatment group showed significant improvements in passive hip extension range of motion (P = .007). Subjects in the treatment group who presented with limited preassessment peak hip extension during walking had increased stride length (P = .019) and peak hip extension (P = .012), and decreased anterior pelvic tilt (P = .006) during walking, whereas subjects in the control group showed only decreased anterior pelvic tilt (P = .013).
The 10-week supervised hip flexor stretching program was effective in increasing stride length and peak hip extension during walking in elderly adults who had limited preintervention hip extension during walking. These results support the use of a simple stretching program for elderly individuals in counteracting age-related decline in gait function.
确定在健康老年人中进行为期 10 周的监督髋关节屈肌拉伸计划是否会增加峰值髋关节伸展、步长和步行速度，并减少行走时的前骨盆倾斜。
双盲、随机、对照试验。
在步态实验室进行治疗前后评估，而拉伸运动在实验室外进行，通常在受试者家中进行。
82 名健康老年人，其中对照组 39 人，治疗组 43 人。
治疗组完成了为期 10 周、每天两次的髋关节屈肌拉伸计划，每周由康复临床医生监督两次。对照组完成了为期 10 周的肩部外展肌拉伸计划。
被动髋关节伸展运动范围、动态峰值髋关节伸展、峰值前骨盆倾斜、步长和行走时的步行速度。
治疗组的被动髋关节伸展运动范围显著改善（P =.007）。在行走时前评估髋关节伸展有限的治疗组受试者中，步长增加（P =.019）和峰值髋关节伸展（P =.012），行走时前骨盆倾斜减少（P =.006），而对照组仅显示前骨盆倾斜减少（P =.013）。
为期 10 周的监督髋关节屈肌拉伸计划可有效增加行走时老年人的步长和峰值髋关节伸展，这些结果支持使用简单的拉伸计划来对抗与年龄相关的步态功能下降。
