To examine the effects of radial nerve mobilization on pain sensitivity and motor performance in subjects with secondary thumb carpometacarpal osteoarthritis.
Randomized controlled trial. Treatment and placebo were given for 4 weeks. Measurements were taken before intervention, after 1 month (first follow-up), and after 2 months (second follow-up).
Patients from the Department of Physical Therapy, Azienda Sanitaria Locale 3, Collegno (Italy).
Participants (N=60; age range, 70-90y) with right-dominant hand secondary thumb carpometacarpal osteoarthritis without other motor-related pathology. All patients completed the study. No patients were withdrawn from the study.
Sliding mobilization of the proximal-distal radial nerve or intermittent ultrasound therapy, used as placebo.
We hypothesized that radial nerve mobilization induces hypoalgesia and increases strength in secondary thumb carpometacarpal osteoarthritis. We measured pressure pain threshold (PPT) at the trapeziometacarpal joint, the tubercle of the scaphoid bone, and the unciform apophysis of the hamate bone by algometry. Tip pinch strength and tripod pinch strength were measured by a mechanical pinch gauge.
Treatment increased PPT by 3.33±.24 kg/cm(2) (P<.001) in the trapeziometacarpal joint and was maintained until first follow-up and second follow-up. Also, PPT in the scaphoid bone and hamate bone was increased (P<.001 and P<.02, respectively). Variables in the placebo group remained unchanged. Tip pinch strength increased by 2.22±.22 kg (P<.04) and tripod pinch strength by 2.83±.24 kg (P<.019).
Radial nerve mobilization decreases pain sensitivity in the trapeziometacarpal joint and increases tip pinch strength.
研究桡神经松动术对继发性拇指腕掌关节炎患者疼痛敏感性和运动功能的影响。
随机对照试验。治疗和安慰剂治疗均持续 4 周。分别在干预前、1 个月（第一次随访）和 2 个月（第二次随访）进行测量。
意大利 Collegno 地区 3 区卫生服务局物理治疗科的患者。
右手优势、患有右拇指腕掌关节炎且无其他运动相关病理学的参与者（60 名；年龄 70-90 岁）。所有患者均完成了研究。无患者退出研究。
桡神经近端-远端滑动松动或间歇性超声治疗，作为安慰剂。
我们假设桡神经松动术可引起继发性拇指腕掌关节炎的痛觉减退，并增强其力量。我们通过压力测痛仪测量了腕掌关节、舟状骨结节和钩骨钩突处的压痛阈值（PPT）。用机械捏力计测量指尖捏力和三指捏力。
治疗组腕掌关节处的 PPT 增加了 3.33±.24 kg/cm(2)（P<.001），并一直维持到第一次随访和第二次随访。此外，舟骨和钩骨处的 PPT 也增加了（P<.001 和 P<.02）。安慰剂组的变量保持不变。指尖捏力增加了 2.22±.22 kg（P<.04），三指捏力增加了 2.83±.24 kg（P<.019）。
桡神经松动术降低了腕掌关节的疼痛敏感性，并增加了指尖捏力。
