Chronic obstructive respiratory diseases (COPD) not only cause damage to the respiratory system as well as the heart and blood vessels of the patient but also have a direct effect on the condition of the musculoskeletal system. The risk of falling is increasing due to dysfunction of the joints as well as aging, which occurs frequently in this population. Gait deficits are known as an important risk factor for falls. This research aimed to investigate the gait of COPD patients compared to healthy people to gain a better understanding of the reasons for falls.
Twenty patients with COPD and 20 age and BMI-matched healthy individuals were included in this study. Sixteen markers were applied to the lower body of the subjects. Spatio-temporal, kinematic, and maximum moment parameters were measured in different phases in three lower body joints, including the hip, knee, and ankle.
The results showed that all spatio-temporal parameters in patients were significantly lower than in healthy people. The ankle angle in the sagittal plane at initial contact was significantly difference ( = 0.03). As well as, in the frontal plane the hip angle in the mid-stance showed a significant difference ( = 0.02). There was also a significant difference in maximum hip moment in the sagittal plane between the two groups ( = 0.01).
The larger hip angle of the patients can be related to the balance problems in the mediolateral direction. The moment showed a significant difference in the hip joint. Since the hip muscles are directly in a synergistic relationship with the trunk muscles, it seems the performance of these muscles is likely to be seriously damaged due to respiratory diseases.
慢性阻塞性呼吸道疾病（COPD）不仅会对患者的呼吸系统以及心脏和血管造成损害，还会直接影响肌肉骨骼系统的状况。由于关节功能障碍以及衰老，该人群中跌倒风险不断增加，而步态缺陷是已知的跌倒重要危险因素。本研究旨在比较COPD患者与健康人的步态，以更好地了解跌倒原因。
本研究纳入了20例COPD患者以及20名年龄和体重指数相匹配的健康个体。在受试者下半身应用了16个标记物。在包括髋、膝和踝在内的三个下半身关节的不同阶段测量时空、运动学和最大力矩参数。
结果显示，患者的所有时空参数均显著低于健康人。初始接触时矢状面的踝关节角度有显著差异（P = 0.03）。此外，在额状面，站立中期的髋关节角度有显著差异（P = 0.02）。两组之间矢状面的最大髋关节力矩也有显著差异（P = 0.01）。
患者较大的髋关节角度可能与内外侧方向的平衡问题有关。髋关节力矩有显著差异。由于髋部肌肉与躯干肌肉直接存在协同关系，似乎这些肌肉的功能很可能因呼吸系统疾病而受到严重损害。
