回復期脳卒中患者におけるロボットスーツHAL^®（Hybrid Assistive Limb^®）福祉用を用いた歩行練習の適応症例およびQOLと気分や感情に対する効果の検討:—ランダム化比較試験の結果から—  [in Japanese] Effects of Gait Training Using a Hybrid Assistive Limb^® (HAL^®) on Quality of Life and Mood States and Suitability of HAL for Recovery Phase Stroke Patients: A Randomized Controlled Study  [in Japanese]

〔目的〕回復期脳卒中片麻痺患者におけるロボットスーツHAL^®を用いた歩行練習の適応症例およびQOLと気分や感情に対する効果について検証すること．〔対象と方法〕脳卒中片麻痺患者24名を2群に無作為に割り付け，HAL^®群はHAL^®を使用した歩行練習，コントロール群は平地歩行練習を週3回合計12回実施し，開始時と終了時に各評価を実施した．〔結果〕介入後，HAL^®群の方が有意に歩行自立度が向上した．一方で，12名中4名は終了時評価においても介助歩行であり，HAL^®の適応とはなりにくい症例であった．〔結語〕HAL^®を使用した歩行練習は，脳卒中片麻痺患者の歩行自立度を向上させる可能性が示唆された．しかし，重度片麻痺や複数の高次脳機能障害を呈する症例は，HAL^®の適応とはなりにくい可能性があると思われた．

[Purpose] To investigate the effects of Hybrid Assistive Limb^® (HAL^®) gait training on the quality of life and mood states, and its suitability for recovery phase stroke patients. [Subjects and Methods] Twenty-four patients with stroke completed the randomized controlled trial. Over 4 weeks, all the patients received twelve 20-min sessions of either HAL or conventional gait training (CGT). The outcome measures were evaluated prior to the training and after the 12 sessions. [Results] The HAL group showed a significant improvement in the Functional Ambulation Category compared with those who received CGT. However, some patients were not suited to HAL training. [Conclusion] The results obtained in this trial suggest that a gait training program based on HAL may improve independent walking more efficiently than one based on CGT. However, severe hemiplegic patients whose nerve signals are not detected by HAL or patients with complicated higher brain dysfunction are not suited to HAL training.
