This study was designed to compare changes in strength after spinal cord injury (SCI) with the use of a hand held myometer to the manual muscle test (MMT). Eighty-eight C4-C8 Frankel A-D tetraplegic subjects were tested at various times up to 2 years post-SCI. Elbow flexor strength on successive examinations were grouped according to their early and later MMT scores (3.5 with no change in MMT. 3.5 to 4.0, and 3.5 to 4.5; 4.0 with no change in MMT, 4.0 to 4.5, and 4.0 to 5.0; 4.5 with no change in MMT, and 4.5 to 5.0). For each group, later myometric measurements (MYO) were expressed as percents of their earlier MYO and were analyzed using paired Student t-tests. Later MYO were 116, 205, 232% (P > 0.05, P < 0.002, P < 0.05) of their earlier MYO for groups 3.5 with no change in the MMT, 3.5 to 4.0, and 3.5 to 4.5 respectively. Later MYO were 140, 139, 191% (P < 0.05, P < 0.02, P < 0.0001) of their earlier MYO for groups 4.0 with no change in MMT, 4.0 to 4.5, and 4.0 to 5.0 respectively. Later MYO were 127 and 126% (P < 0.01, P < 0.02) of their earlier MYO for groups 4.5 with no change in MMT and 4.5 to 5.0 respectively. In conclusion the hand held myometer detected changes in muscle strength not detected by the MMT.
本研究旨在比较脊髓损伤（SCI）后使用手持式肌动计与徒手肌力测试（MMT）时的力量变化。88名C4 - C8级Frankel A - D级四肢瘫痪受试者在SCI后长达2年的不同时间接受测试。连续检查时的肘屈肌力量根据其早期和后期的MMT评分进行分组（MMT无变化为3.5；3.5至4.0，以及3.5至4.5；MMT无变化为4.0，4.0至4.5，以及4.0至5.0；MMT无变化为4.5，以及4.5至5.0）。对于每组，后期的肌动计测量值（MYO）表示为其早期MYO的百分比，并使用配对学生t检验进行分析。MMT无变化的3.5组、3.5至4.0组和3.5至4.5组后期的MYO分别为其早期MYO的116%、205%、232%（P>0.05，P<0.002，P<0.05）。MMT无变化的4.0组、4.0至4.5组和4.0至5.0组后期的MYO分别为其早期MYO的140%、139%、191%（P<0.05，P<0.02，P<0.0001）。MMT无变化的4.5组和4.5至5.0组后期的MYO分别为其早期MYO的127%和126%（P<0.01，P<0.02）。总之，手持式肌动计检测到了MMT未检测到的肌肉力量变化。
