It has recently been suggested that people with chronic obstructive pulmonary disease have an increased risk of falls. Although falls risk is multifactorial, impaired balance may contribute. The primary aim of this study was to compare balance between people with and without chronic obstructive pulmonary disease and the secondary aim was to determine if balance deteriorates when respiratory demand is increased by upper limb exercise.
Twelve people with chronic obstructive pulmonary disease and 12 healthy control subjects participated in this study. Participants stood on a force plate to record centre of pressure displacement during a range of conditions that challenge balance. Lumbar spine and hip motion were measured with inclinometers. Balance trials were performed before and after participation in upper limb exercise that increased respiratory demand in those with chronic obstructive pulmonary disease.
People with chronic obstructive pulmonary disease had increased mediolateral centre of pressure displacement and increased angular motion of the hip compared to healthy controls. Mediolateral centre of pressure displacement was further increased in people with chronic obstructive pulmonary disease following exercise, but unchanged in controls. Anteroposterior centre of pressure displacement did not differ between groups.
People with chronic obstructive pulmonary disease have reduced control of balance in the mediolateral direction. This may contribute to an increased risk of falls in this population.
最近有人提出，慢性阻塞性肺疾病患者跌倒的风险增加。尽管跌倒风险是多因素的，但平衡受损可能是原因之一。本研究的主要目的是比较慢性阻塞性肺疾病患者与无慢性阻塞性肺疾病患者之间的平衡，次要目的是确定当呼吸需求因上肢运动而增加时，平衡是否会恶化。
本研究纳入了 12 名慢性阻塞性肺疾病患者和 12 名健康对照组。参与者站在力板上，在一系列挑战平衡的条件下记录身体重心的位移。用测斜仪测量腰椎和髋关节的运动。在增加慢性阻塞性肺疾病患者呼吸需求的上肢运动后，在运动前和运动后进行平衡试验。
与健康对照组相比，慢性阻塞性肺疾病患者的身体重心横向位移和髋关节角度运动增加。但慢性阻塞性肺疾病患者在运动后其身体重心横向位移进一步增加，而对照组则没有变化。前后向身体重心位移在两组之间没有差异。
慢性阻塞性肺疾病患者的平衡控制能力在横向方向上降低。这可能导致该人群跌倒的风险增加。
