背景:甲状腺功能减退综合征(HMS),或有限的髋关节运动范围(ROM),经常在接受大量训练的青少年中报道。本研究旨在调查传统静态拉伸(STR)和自我肌筋膜释放(MFR)对HMS髋关节青少年的影响。
方法:本研究为随机对照试验。髋关节HMS的青少年运动员分为23STR和23MFR。采用泡沫滚动作为MFR的训练方法。两种干预措施均在6周内每天进行两次,持续20分钟。培训是通过移动视频拍摄和分发的。自我评估的哥本哈根髋关节和腹股沟结果评分,ROM,力量,和跳跃测试在干预前后进行测量。无限制的健康侧被指定为非HMS(nHMS)并作为参考值。
结果:研究参与者在屈曲(FLX)方面存在局限性,绑架(ABD),内部旋转(IR),和外部旋转(ER)。STR组的ROM恢复至nHMS水平。MFR组的FLX和ABD也恢复,然而,与nHMS相比,IR和ER的角度较低。MFRFLX,ABD,ER强度,单跳测试像nHMS一样恢复,然而,尽管改善,STR组显著低于nHMS.两组均描述了较低的干预前哥本哈根髋关节和腹股沟结果评分子量表日常生活活动,运动,和体力活动相比nHMS。干预后日常生活活动和体力活动均提高到健康水平,然而,运动低于nHMS。
结论:STR和MFR对髋关节活动度和髋关节自评评分均有影响。此外,MFR在FLX中的强度有所改善,ABD,和ER。然而,MFR组关于三元组的改进,交叉跳跃,和自我评估的运动是有限的。因此,STR和MFR不仅可有效改善ROM,还可有效改善HMS髋关节的肌肉功能不对称。
BACKGROUND: Hypomobility syndrome (HMS), or limited hip range of motion (ROM), is often reported in adolescents who train heavily. This
study was aimed to investigate the impact of traditional static stretching (STR) and self-myofascial release (MFR) in adolescents with HMS hip.
METHODS: This
study was a randomized controlled
trial. Adolescent athletes with HMS hip were grouped as 23 STR and 23 MFR. Foam rolling was employed as the training method for MFR. Both interventions were performed twice a day for 20 minutes in 6 weeks. The training was filmed and distributed via the mobile video. Self-assessed Copenhagen Hip & Groin Outcome Score, ROM, strength, and hop tests were measured before and after the interventions. The healthy side without limitations was designated as non-HMS (nHMS) and taken as reference value.
RESULTS: The
study participants had limitations in flexion (FLX), abduction (ABD), internal rotation (IR), and external rotation (ER). The ROM of STR group was recovered to nHMS level. The FLX and ABD of MFR group was also recovered, however the IR and ER had lower angles compared to nHMS. MFR FLX, ABD, ER strength, and single hop test were restored like that of nHMS, however STR group was substantially lower than nHMS despite the improvements. Both groups depicted lower pre-intervention Copenhagen Hip & Groin Outcome Score subscale activities daily living, sport, and physical activity compared to nHMS. Activities daily living and physical activity were improved to healthy levels after the intervention, however sport was lower than that of nHMS.
CONCLUSIONS: Both STR and MFR had impact on hip mobility and hip self-assessment score. Furthermore, MFR had strength improvements in FLX, ABD, and ER. However, the improvements in MFR group regarding triples, crossover hops, and self-assessed sports were limited. Therefore, STR and MFR are effective in improving not only ROM but also muscle function asymmetry in HMS hip.
