To compare the effects of dynamic oscillatory stretch and static stretching techniques in order to improve hamstring extensibility in healthy individuals with asymptomatic hamstring tightness.
The single-blind randomised controlled trial was conducted from March to June 2018 at Sadiq Hospital, Sargodha Institute of Health Sciences, and District Headquarter Teaching Hospital,Sargodha, Pakistan, and comprised young healthy individuals with hamstring tightness who were randomly divided into groups 1 and 2, with the former getting exposure to oscillatory stretch technique and the latter to static stretching technique. Assessment of hamstring length was done using reliable clinical measurement test along with pain for stretch tolerance during passive straight leg raise using numeric pain rating scale. Measurements were taken at baseline, immediate (10min) and 1 hourpost-intervention. Data was analysed using SPSS 20.
Of the 83 subjects, 42(%) were in group 1 with a mean age of 24.22±4.09 years, and 41(%) were in group 2 with a mean age of 25.85±6.09 years.Group1 showed significantly more improvement in all variables of hamstring flexibility and perceived pain at both post-intervention checkups compared to group 2 (p<0.05).
Dynamic oscillatory stretch technique was found to be more effective in improving hamstring flexibility and perceived pain compared to static stretching technique.
比较动态振荡拉伸和静态拉伸技术对改善无症状绳肌紧张的健康个体绳肌伸展性的效果。
2018年3月至6月在巴基斯坦萨戈达卫生科学研究所萨迪克医院和萨戈达地区总部教学医院进行了单盲随机对照试验，纳入了有绳肌紧张的年轻健康个体，随机分为1组和2组，前者接受振荡拉伸技术，后者接受静态拉伸技术。使用可靠的临床测量测试评估绳肌长度，并使用数字疼痛评分量表评估被动直腿抬高时的拉伸耐受疼痛。在基线、干预后即刻（10分钟）和1小时进行测量。使用SPSS 20分析数据。
83名受试者中，42名（%）在1组，平均年龄24.22±4.09岁，41名（%）在2组，平均年龄25.85±6.09岁。与2组相比，1组在干预后两次检查时绳肌柔韧性和感知疼痛的所有变量上均有显著改善（p<0.05）。
与静态拉伸技术相比，动态振荡拉伸技术在改善绳肌柔韧性和感知疼痛方面更有效。
