ヒーリングタッチによる就労後看護師の疲労感に対する効果の検討

Study on Effectiveness of Healing Touch for Fatigued Nurses after Work

要旨

　目的：就労後看護師の疲労感軽減に，ヒーリングタッチが有効であるか検討する．

　方法：研究デザインは無作為化比較試験（RCT）である．調査対象は，東京都内のA病院に勤務する，日勤勤務終了直後の常勤看護師76名である．調査方法は，対象者を無作為にヒーリングタッチ群または対照群に分け，両群とも20分間の介入をした．測定項目は，主観的評価として，疲労感（VAS）と疲労にまつわる気分（POMS）を介入前後に測定した．客観的評価として，指尖脈波による自律神経活動（心拍数，HF，LF/HF）を介入前・中・後において測定した．

　結果：1. VASの変化量は，ヒーリングタッチ群の疲労感が有意に軽減した（p＜0.01）．2. POMSの変化量は，総合的な気分状態を表すTMD得点が，ヒーリングタッチ群は有意に改善していた（p＜0.05）．3. 自律神経活動では，ヒーリングタッチ群において介入中にHFが有意に上昇し，副交感神経活動が亢進していた（p＜0.05）．心拍数，LF/HFは変化が見られなかった．

　結論：就労後の看護師がヒーリングタッチにより，疲労感が軽減されることが示唆された．

　Purpose: Verify the effectiveness if Healing Touch works for fatigued nurses after work.

　Methods: The study was executed based on RCT (Randomized Controlled Trial). Targeted people were consisted of 76 full-time nurses who were working at a hospital in Tokyo, after day-time work. Nurses were randomly grouped into Healing Touch group or Placebo Healing Touch group, and intervened 20 minutes. Estimation was done on subjective and objective perspectives. As subjective estimation, tiredness (based on VAS: Visual Analogue Scale) and fatigue feeling (based on POMS: Profile of Mood States) were observed before and after the intervention. As for objective evaluation, plethysmogram of fingers was applied to measure Autonomic Nervous Activity such as Heart Rate, HF, LF/HF before, during and after the intervention.

　Results: 1. Variance of VAS showed Healing Touch effected significantly against relaxing the fatigue (p＜0.01). 2. Variance of POMS showed Healing Touch significantly improved TMD Score, which represented overall feeling status (p＜0.05). 3. Healing Touch also worked for Autonomic Nervous Activity, showing significant increase in HF, resulting in improving Parasympathetic Nerve Activity (p＜0.05). There was no significant move on Heart Rate and LF/HF.

　Conclusion: Healing Touch was proved to be effective on relaxing fatigues of nurses who were after work.
