It has been reported that hypermobile subjects have proprioceptive deficits. However, it remains unclear whether pain-free subjects with hypermobility also have deficits.
Ten subjects with hypermobility and nine without hypermobility were recruited following ethical approval and informed consent. Shoulder mobility, joint position sense (JPS) and a reflex of trapezius evoked from arm afferents were compared.
There was greater shoulder mobility in the hypermobile group (p = 0.004). There were no differences in shoulder JPS between the groups (p = 0.27), although, the hypermobile group displayed a larger degree of variability (p = 0.014). Finally, there were no differences in the latency of upper and lower trapezius reflexes evoked from arm afferents (p = 0.86 and 0.98, respectively).
In a group of people with hypermobility without shoulder problems, there was no difference in either shoulder JPS or reflex latency when compared with a non- hypermobile group. The relevance of pain to proprioceptive deficits is discussed.
据报道，关节活动过度的受试者存在本体感觉缺陷。然而，尚无疼痛的关节活动过度受试者是否也存在缺陷仍不清楚。
在获得伦理批准并取得知情同意后，招募了10名关节活动过度的受试者和9名非关节活动过度的受试者。比较了肩部活动度、关节位置觉（JPS）以及由手臂传入神经诱发的斜方肌反射。
关节活动过度组的肩部活动度更大（p = 0.004）。两组之间的肩部JPS无差异（p = 0.27），不过，关节活动过度组的变异性更大（p = 0.014）。最后，由手臂传入神经诱发的上、下斜方肌反射潜伏期无差异（分别为p = 0.86和0.98）。
在一组无肩部问题的关节活动过度人群中，与非关节活动过度组相比，肩部JPS或反射潜伏期均无差异。讨论了疼痛与本体感觉缺陷的相关性。
