People with chronic neck pain show decreased endurance and strength of cervical muscles with compromised respiratory function. There is little evidence that improvement in breathing function of people with neck pain can help in enhancing cervical muscle strength and pulmonary function. The objective of this our clinical trial was to examine the effects of breathing re-education combined with physiotherapy on endurance and strength of deep neck flexors, and pulmonary function in patients with chronic neck pain.
METHODS/DESIGN: In this double blind randomised clinical trial, 30 patients with chronic neck pain (25-50 years old) were randomly allocated to two groups. Group A, physiotherapy ( = 15), and Group B, breathing re-education ( = 15). The duration of intervention was eight weeks with treatment five days a week. The endurance was measured with the craniocervical flexion test, strength with a handheld dynamometer (Baseline USA) and pulmonary functions with the Spiro lab 4 (USA) at baseline, at week four and at week eight of the intervention.
There was a significant between group improvement in the strength of deep neck flexors and forced vital capacity (FVC) in Group B = 0.0001 and = 0.0200 ( ˂ 0.05) respectively. Intergroup comparisons showed no significant differences for endurance, cervical extensor strength, Forced Expiratory Volume in one second (FEV1), and FEV1/FVC percentage.
Our study concluded that breathing re-education combined with other physiotherapy management is effective for improving the strength of neck flexors and increasing FVC in people with chronic neck pain.
Breathing re-education may be part of physiotherapy management in patients with chronic neck pain.

慢性颈痛患者颈部肌肉耐力和力量下降，呼吸功能受损。几乎没有证据表明改善颈痛患者的呼吸功能有助于增强颈部肌肉力量和肺功能。本临床试验的目的是研究呼吸再训练联合物理治疗对慢性颈痛患者深层颈屈肌耐力和力量以及肺功能的影响。
方法/设计：在这项双盲随机临床试验中，30例慢性颈痛患者（年龄25 - 50岁）被随机分为两组。A组为物理治疗组（n = 15），B组为呼吸再训练组（n = 15）。干预为期8周，每周治疗5天。在干预的基线、第4周和第8周，通过颅颈屈曲试验测量耐力，用手持测力计（美国基线公司）测量力量，用Spiro lab 4（美国）测量肺功能。
B组深层颈屈肌力量和用力肺活量（FVC）在组间有显著改善，分别为P = 0.0001和P = 0.0200（P ˂ 0.05）。组间比较显示，在耐力、颈伸肌力量、一秒用力呼气量（FEV1）和FEV1/FVC百分比方面无显著差异。
我们的研究得出结论，呼吸再训练联合其他物理治疗方法对改善慢性颈痛患者的颈屈肌力量和增加FVC有效。
呼吸再训练可能是慢性颈痛患者物理治疗的一部分。
