背景:为了更好地个性化治疗并监测腰痛患者的康复情况,感觉运动功能的客观测试,如腰椎本体感觉,必须根据它们的信度和效度进行选择。这项研究的主要目的是测试三种腰椎本体感觉方法的同时有效性。
方法:31名参与者进行了三项腰椎本体感觉测试(运动知觉阈值,主动和被动关节定位感觉),整个身体的流动性和平衡(时间上升和运行)和两个躯干特定的姿势控制(稳定性阈值和基于传感器的摇摆措施)测试。
结果:只有运动知觉阈值本体感觉测试显示出一定的有效性,与躯干特定姿势控制测试相关[r范围(正值):0.37至0.60]。三种腰椎本体感觉测量值彼此不相关。稳定性度量的阈值与时间上升(r=0.37)和特定于躯干的(基于传感器的摇摆度量)姿势控制[r范围(正值):0.48至0.77]测试相关。
结论:本研究产生了三个原始发现。只有运动知觉阈值本体感觉测试证明了其并发有效性。事实上,本研究中进行的三项腰椎本体感觉测试彼此不相关,从而评估不同的结构。最后,针对其他测试验证了稳定性方案的阈值.这些发现将有助于选择最合适的腰椎本体感觉措施,以研究运动疗法对背痛患者的影响。
BACKGROUND: To better personalize treatment and monitor recovery of individuals with low back pain, objective tests of sensorimotor functions, such as lumbar proprioception, must be selected based on their reliability and validity. The primary objective of this study was to test the concurrent validity of three measures of lumbar proprioception.
METHODS: Thirty-one participants performed three lumbar proprioception tests (motion perception threshold, active and passive joint positioning sense), a whole-body mobility and balance (time up-and-go) and two trunk-specific postural control (threshold of stability and sensor-based sway measures) tests.
RESULTS: Only the motion perception threshold proprioception test showed some validity, correlating with the trunk-specific postural control tests [r range (positive values): 0.37 to 0.60]. The three lumbar proprioception measures were not correlated to each other. The threshold of stability measure was correlated with the time up-and-go (r = 0.37) and trunk-specific (sensor-based sway measures) postural control [r range (positive values): 0.48 to 0.77] tests.
CONCLUSIONS: The present study generated three original findings. Only the motion perception threshold proprioception test demonstrated its concurrent validity. In fact, the three lumbar proprioception tests performed in the present study were not correlated to each other, thus assessing different constructs. Finally, the threshold of stability protocol was validated against other tests. These findings will help in selecting the most appropriate lumbar proprioception measures to study the effects of exercise treatments in patients with back pain.
