Teaching is one of the professions where incidence and prevalence of neck pain is high. Prolonged use of computers, which has further increased due to online teaching amid pandemic, is known to cause neck pain and alter posture, while people with forward head posture (FHP) are prone to develop neck pain and related disability. Research has shown that impairment of deep cervical flexor (DCF) muscles leads to insufficiency in coordination, activation, overload, and poor support on cervical structures that further lead to development of neck pain and altered neck posture. The objective of this study was to see the effect of DCF muscle training using pressure biofeedback on pain and FHP in school teachers with neck pain.
This observational study was conducted at medical center in school premises. Fifty-five school teachers aged between 25 and 40 years with experience of more than 5 years were invited to participate in this study. Subjects were divided in two groups. Both the groups received conventional exercises while in experimental group DCF muscle training using pressure biofeedback was given additionally. Pain and FHP were assessed using NPRS and cranio-vertebral angle using digital photograph technique, respectively, at baseline and end of four weeks of treatment.
Although pain and FHP improved in both the groups, mean improvement in both the measures was more in the group that also received DCF training using pressure biofeedback.
This study shows that although pain and FHP improved following conventional exercises in school teachers with neck pain, mean improvement was more significant among those who received additional DCF muscle training using pressure biofeedback.
教师职业是颈部疼痛发病率和患病率较高的职业之一。由于疫情期间在线教学的增加,计算机的长期使用会导致颈部疼痛并改变姿势,而头部前倾姿势(FHP)的人更容易出现颈部疼痛及相关残疾。研究表明,颈深屈肌(DCF)肌肉功能受损会导致协调、激活、负荷和对颈椎结构的支撑不足,进而导致颈部疼痛和颈部姿势改变。本研究的目的是观察使用压力生物反馈进行DCF肌肉训练对颈部疼痛的学校教师疼痛和FHP的影响。
本观察性研究在学校内的医疗中心进行。邀请了55名年龄在25至40岁之间、教龄超过5年的学校教师参与本研究。受试者分为两组。两组均接受常规锻炼,而实验组额外进行使用压力生物反馈的DCF肌肉训练。分别在基线和治疗四周结束时,使用数字摄影技术通过NPRS评估疼痛和FHP,通过颅椎角评估。
尽管两组的疼痛和FHP均有所改善,但在同时接受使用压力生物反馈的DCF训练的组中,这两项指标的平均改善程度更大。
本研究表明,尽管颈部疼痛的学校教师在进行常规锻炼后疼痛和FHP有所改善,但在接受额外的使用压力生物反馈的DCF肌肉训练的教师中,平均改善更为显著。
