Individuals with unilateral hip osteoarthritis walk with kinematic and spatiotemporal compensations compared to healthy individuals. Our purpose was to determine associations between gait, pain, and functional performance during the six-minute walk test.
Trunk and hip kinematics and spatiotemporal gait outcomes were recorded from individuals with unilateral hip osteoarthritis using inertial sensors (Xsens Technologies). Pain was collected prior to and at the end of the six-minute walk test. Paired t-tests were conducted to evaluate gait between limbs and between the first and final minutes of walking. Correlations were conducted between gait, pain, and six-minute walk test performance.
Nineteen participants (8 females, age: 63 ± 5 yrs.
, BMI: 29.0 ± 4.5 kg/m) completed the study. Between-limb differences in hip flexion, hip extension, and trunk forward flexion peak angles were observed during the six-minute walk test (P < .05). Participants demonstrated an increase in trunk forward flexion of the osteoarthritis side (t = -2.34, P = .031) and a bilateral decrease in stride length (osteoarthritis limb: t = 2.98, P = .008, non- osteoarthritis limb: t = 3.17, P = .006) from the first to the final minute of walking. Greater pain was associated with greater osteoarthritis limb hip extension (first minute: r = -0.506, P = .027, final minute: r = -0.53, P = .020) and greater hip abduction (r = 0.46, P = .046) during the final minute of walking.
Gait compensations increase throughout the six-minute walk test, and pain associates with hip kinematics during the six-minute walk test. Wearable technology may allow for more accurate clinical movement assessments.
与健康个体相比，单侧髋关节炎患者在行走时会出现运动学和时空补偿。我们的目的是确定在 6 分钟步行测试期间步态、疼痛和功能表现之间的相关性。
使用惯性传感器（Xsens Technologies）从单侧髋关节炎患者身上记录躯干和髋关节运动学以及时空步态结果。在 6 分钟步行测试前后采集疼痛数据。进行配对 t 检验以评估四肢之间以及行走的前 1 分钟和最后 1 分钟之间的步态。进行步态、疼痛和 6 分钟步行测试表现之间的相关性分析。
19 名参与者（8 名女性，年龄：63±5 岁，BMI：29.0±4.5kg/m2）完成了研究。在 6 分钟步行测试中观察到髋关节屈曲、髋关节伸展和躯干前屈峰值角度的肢体间差异（P<.05）。参与者在关节炎侧出现躯干前屈增加（t=-2.34，P=.031），双侧步长减少（关节炎侧：t=2.98，P=.008，非关节炎侧：t=3.17，P=.006），从第 1 分钟到最后 1 分钟。更大的疼痛与更大的关节炎侧髋关节伸展（第 1 分钟：r=-0.506，P=.027，最后 1 分钟：r=-0.53，P=.020）和更大的髋关节外展（r=0.46，P=.046）在最后 1 分钟的行走时相关。
在 6 分钟步行测试过程中，步态补偿逐渐增加，疼痛与 6 分钟步行测试期间的髋关节运动学相关。可穿戴技术可能允许更准确的临床运动评估。
