To assess the dynamic activity of scapular muscles in patients with accessory nerve dysfunction after neck dissection surgery, compared with both their unaffected side and with age- and sex-matched controls.
A case-control investigation.
Physiotherapy department of a hospital.
Two groups of 10 participants were recruited. One group consisted of neck dissection patients with demonstrated clinical signs of accessory nerve injury. The second group was composed of matched healthy individuals.
Surface electromyographic activity of the upper trapezius, middle trapezius, rhomboid major, and serratus anterior muscles was compared dynamically during scapular strengthening exercises.
Electromyographic activity comparisons were made between the neck dissection affected side, the neck dissection unaffected side, and the matched healthy control side. Raw data and data expressed as a percentage of maximal voluntary isometric contraction were compared.
The neck dissection affected side demonstrated significantly less upper trapezius and middle trapezius muscle activity compared with the neck dissection unaffected side and matched control group. The neck dissection unaffected side had significantly less upper trapezius muscle activity than the matched control group.
Trapezius muscle activity is significantly reduced in accessory nerve shoulder dysfunction as a result of neck dissection, both in the affected and unaffected sides. This needs to be considered in the rehabilitation of this patient group.
评估颈清扫术后副神经功能障碍患者肩胛骨肌肉的动态活动，与未受影响侧以及年龄和性别匹配的对照组进行比较。
病例对照研究。
医院理疗科。
招募了两组各 10 名参与者。一组是临床证实有副神经损伤的颈清扫患者。第二组由匹配的健康个体组成。
在进行肩胛骨强化锻炼时，比较斜方肌上、中束、菱形肌和前锯肌的表面肌电图活动。
比较颈清扫术受影响侧、颈清扫术未受影响侧和匹配健康对照组之间的肌电图活动。比较原始数据和以最大随意等长收缩百分比表示的数据。
与颈清扫术未受影响侧和匹配对照组相比，颈清扫术受影响侧的斜方肌上、中束肌肉活动明显减少。颈清扫术未受影响侧的斜方肌上束肌肉活动明显少于匹配对照组。
由于颈清扫术，副神经肩功能障碍患者的斜方肌活动明显减少，受影响侧和未受影响侧均如此。在对该患者组进行康复治疗时需要考虑到这一点。
