摘要：

目的 探究不同测试体位对手、腕屈曲肌群定量肌力的影响，建立各肌群的标准化肌力检测方案。 方法 征集40例健康受试者（男性12例，女性28例），使用Micro FET2TM便携式数字肌力测试仪，分别于腕关节背伸30°位、中立0°位和掌屈30°位测量各手指屈曲及腕关节掌屈肌力，分别于拇指掌侧外展30°位和60°位测量拇指掌侧外展肌力。从40例受试者中随机抽取10例，间隔10~15 d后由同一操作者再次测试各肌群定量肌力。 结果 除男性腕关节背伸30°位和中立0°位之间的拇指屈曲肌力、腕关节掌屈肌力差异无统计学意义（P>0.05），各指屈曲及腕掌屈肌力值主要呈现以下特点：腕关节背伸30°位>腕关节中立0°位>腕关节掌屈30°位，拇指掌侧外展30°位>60°位；所有受试者手指屈曲肌力均为拇指>示指>中指>环指>小指；男性各项肌力值均大于女性（P<0.05）；所有受试者左、右侧肌力值的差异均无统计学意义（P>0.05）。10例受试者不同时期测量肌力值的可靠性良好。 结论 手、腕各肌群定量肌力均受体位影响，鉴定过程中应采取规范、统一的测试体位。Micro FET2TM用于手、腕关节定量肌力测试具有良好的可靠性。腕关节背伸30°位可作为各手指屈曲肌力及腕关节掌屈肌力的最佳标准化检测条件。拇指掌侧外展30°位可作为拇指掌侧外展肌力的最佳标准化检测条件。

Abstract:

Objective To explore the effects of different test positions on quantitative muscle strength of wrist and finger flexor muscle groups and to establish a standardized muscle strength test protocol for each muscle group. Methods Forty healthy subjects （12 males and 28 females） were recruited. A portable digital quantitative muscle strength tester, Micro FET2TM, was used to measure the flexor muscle strength of each finger and the wrist joint at the 30° extension, 0° neutral, and 30° flexion, respectively. Palmar abduction strength of the thumb was measured at 30° and 60°, respectively. Ten subjects were randomly selected from the 40 subjects, and the quantitative muscle strength of each muscle group was tested again by the same operator after an interval of 10 to 15 days. Results Except for the fact that in males, there was no significant difference in flexor muscle strength of thumb and wrist joint between 30° of wrist extension and neutral 0° position, the muscle strength of the other fingers flexion and wrist palmar flexor showed the following characteristics： 30° of wrist extension > neutral 0° position > 30° of flexion, and the PAST was 30°>60°; The flexor muscle strength of all the subjects was thumb > index finger > middle finger > ring finger > little finger; All muscle strength values of male were greater than those of female, and the difference was statistically significant （P<0.05）; There was no significant difference between the left and right side muscle strength values of all subjects （P>0.05）. The reliability of muscle strength values measured at different times in 10 subjects was good. Conclusion The quantitative muscle strength of each muscle group of the hand and wrist is affected by the test position, and a standardized and uniformed test position should be adopted in the actual identification. Micro FET2TM has good reliability for hand and wrist quantitative muscle strength testing. The 30° extension of the wrist can be used as the best standardized test position for the flexion muscle strength of each finger and wrist joint. The 30° position can be used as the best standardized test position for PAST.
