Abstract：
Forward head posture (FHP) is a common postural displacement that is significantly associated with neck pain, with higher risks of having neck pain in female and older populations. This study investigated the effect of two different forward head posture (FHP) interventions in elderly participants with poor posture and non-specific neck pain. Sixty-six elderly participants with a craniovertebral angle (CVA) < 50° were randomized into either a Chiropractic Biophyics® (CBP®) or a standardized exercise based FHP correction group (Standard Group). Both groups were treated for 18 sessions over a 6-week period. A 3-month post-treatment follow-up was also assessed with no further interventions. The CBP group received a mirror image® exercise and a Denneroll™ cervical traction orthotic (DCTO); the standard group performed a protocol of commonly used stretching and strengthening exercises for the neck. Both groups received 30 min of their respective interventions per session. The primary outcome was the CVA, with secondary outcomes including pain intensity, Berg balance score (BBS), head repositioning accuracy (HRA), and cervical range of motion (CROM). After 18 sessions (6 weeks later), the CBP group had statistically significant improvement in the CVA (p < 0.001), whereas the standard group did not. In contrast, both groups showed improved functional measurements on the BBS and HRA as well as improved pain intensity. However, at the 3-month follow-up (with no further treatment), there were statistically significant differences favoring the CBP group for all outcomes (p < 0.001). The differences in the between group outcomes at the 3-month follow-up indicated that the improved outcomes were maintained in the CBP group, while the standard group experienced regression of the initially improved outcomes at 6 weeks. It is suggested that the improvement in the postural CVA (in the CBP group but not in the standard group) is the driver of superior and maintained pain and functional outcomes.
摘要：
前头姿势（FHP）是一种常见的姿势位移，与颈部疼痛显著相关。女性和老年人患颈部疼痛的风险更高。这项研究调查了两种不同的前头部姿势（FHP）干预措施对姿势不良和非特异性颈部疼痛的老年参与者的影响。66名颅椎角（CVA）＆lt;50°的老年参与者被随机分为整脊Biophyics®（CBP®）或基于标准化运动的FHP矫正组（标准组）。两组均在6周内接受18次治疗。还评估了治疗后3个月的随访，没有进一步的干预措施。CBP组接受了镜像®锻炼和Denneroll™颈椎牵引矫正器（DCTO）；标准组执行了常用的颈部拉伸和强化锻炼方案。两组均接受每次30分钟的干预。主要结果是CVA,次要结果包括疼痛强度，伯格平衡评分（BBS），磁头重新定位精度（HRA），和颈椎活动范围（CROM）。经过18次会议（6周后），CBP组的CVA有统计学上的显着改善（p＆lt;0.001），而标准组没有。相比之下,两组在BBS和HRA上的功能测量均有改善,疼痛强度也有改善.然而,在3个月的随访（没有进一步的治疗），对于所有结局,CBP组均有统计学差异(p<0.001).3个月随访时组间结果的差异表明，CBP组的改善结果得以维持，而标准组在6周时经历了最初改善的结局的消退。建议姿势性CVA的改善（在CBP组中，而不是在标准组中）是优越且维持疼痛和功能结果的驱动因素。
