Abstract

Context: Poor knee biomechanics contribute to knee joint injuries. Neuromuscular control over knee position is partially derived from the hip. It is unknown whether isolated activation training of the gluteal muscles improves lower-extremity frontal plane mechanics. This study examined if a home-based hip muscle activation program improves performance on the Forward Step-Down Test as well as increases surface electromyography (sEMG) activation of the gluteal muscles.

Design: The study utilized a single-group repeated-measures design.

Methods: Thirty-five participants (24 females, mean age = 23.17 [SD 1.36] years) completed an 8-week hip muscle activation program. The Forward Step-Down Test score and sEMG of gluteus maximus and medius were assessed preintervention and postintervention.

Results: Forward Step-Down Test scores improved significantly from preintervention (Mdn = 3.5) to postintervention (Mdn = 3.0, T = 109, P = .010, r = .31.), but this result did not meet clinical significance. sEMG analysis revealed a significant increase in mean gluteus maximus activation (P = .028, d = 1.19). No significant dose-response relationship existed between compliance and the Forward Step-Down Test scores or sEMG results.

Conclusions: A home-based hip activation program increases gluteus maximus activation without clinically significant changes in frontal plane movement quality. Future studies may find clinical relevance by adding motor learning to the activation training program to improve functional muscle use.

髋关节肌肉激活家庭锻炼计划是否会改变向前下蹲测试的运动模式?
背景:不良的膝关节生物力学会导致膝关节损伤。膝关节位置的神经肌肉控制部分来自臀部。臀部肌肉的孤立激活训练是否能改善下肢前平面力学尚不清楚。本研究探讨了基于家庭的臀部肌肉激活训练是否能提高前倾下蹲测试(Forward Step-Down Test)的成绩,以及是否能增加臀部肌肉的表面肌电图(sEMG)激活:研究采用单组重复测量设计:35 名参与者(24 名女性,平均年龄 = 23.17 [SD 1.36] 岁)完成了为期 8 周的臀部肌肉激活计划。对干预前和干预后的前倾下蹲测试得分以及臀大肌和臀中肌的 sEMG 进行评估:从干预前(Mdn = 3.5)到干预后(Mdn = 3.0,T = 109,P = .010,r = .31.),前向下台阶测试得分有了显著提高,但这一结果不具有临床意义。顺应性与前进一步测试得分或 sEMG 结果之间不存在明显的剂量反应关系:结论:基于家庭的髋关节激活计划能增加臀大肌的激活,而不会对正面平面运动质量产生明显的临床变化。未来的研究可能会通过在激活训练计划中加入运动学习来提高肌肉的功能性使用,从而发现其临床意义。

期刊介绍: The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
