測量:運動功能
晚發型SMA(II型與III型)

Hammersmith運動功能評分量表-增訂版 (HFMSE) 已經用於多項臨床試驗,用以評估晚期發病型 (II型和III型) 脊髓性肌肉萎縮症病患的運動功能。

HFMSE量表包含主要動作功能評估量表(GMFM)中與躺臥/滾動、爬行、爬行/跪姿、站立、行走/跑步/跳躍相關的13個臨床項目4,14,15

  • 考試包含33個項目,評分為0-2
  • 總分在0到66之間,分數越低表示運動功能越差
  • 患者的疲勞程度是一個重要的考慮因素,HFMSE可以在12分鐘內完成(平均時間)

晚期發作型SMA患者(II型和III型)的HFMSE評分可能會逐漸下降。4

一項SMA的自然病史研究報告顯示,晚發型SMA病患的HFMSE評分12個月內下降0.56分(平均值)。4 然而在另一項研究中,晚發型SMA病患(n=79)的運動功能以非線性方式下降。HFMSE評分在36個月內的平均變化為-1.71(P = 0.01)。 研究期間中16

  • 2位有2個SMN2基因拷貝數的病患喪失坐起能力
  • 1位有3個SMN2基因拷貝數的病患喪失坐起能力
  • 5位有3個SMN2基因拷貝數的病患喪失行走能力
