手根管症候群患者における鏡視下手根管開放術術後のDASH（Disabilities of the Arm, Shoulder and Hand）得点とその関連因子

DASH (Disabilities of the Arm, Shoulder and Hand) and related factors after endoscopic carpal tunnel release in patients with carpal tunnel syndrome

要旨：手根管症候群（以下，CTS）患者の鏡視下手根管開放術（以下，ECTR）術後急性期のDisabilities of the Arm, Shoulder and Hand（以下，DASH）得点，およびそれに関連する因子を検討した．CTS患者56名を対象に，DASHの得点を術前と術後1週間に測定し，同時に関連因子として痺れ，痛み，触覚，手指可動域，握力，不安感を測定した．術後のDASHの総得点は，術前と比較して有意に増加，すなわち主観的上肢能力は悪化した．この術後のDASHの得点増加には，主に痛み，握力，不安感が影響していた．CTS患者のECTR術後急性期の主観的上肢能力の改善には，これらの因子に対する介入の重要性が示唆された．

　We compared the scores of DASH (Disabilities of the Arm, Shoulder and Hand) and related factors with the post surgery scores after endoscopic carpal tunnel release (ECTR) in patients with carpal tunnel syndrome (CTS-patients). Fifty-six CTS-patients' DASH scores were measured before the ECTR, one week after ECTR, and during ECTR. Numbness, pain, sense of touch, range of motion, grip strength and anxiety were assessed as the factors that might affect the DASH scores. Total DASH scores after surgery increased more significantly than those before surgery, suggesting the deterioration of subjective ability of the upper extremity. Pain, grip strength and anxiety were related to the increase in DASH scores after surgery. The results suggest that interventions treating these factors are important for the effective improvement of subjective ability of upper extremity of CTS-patients in the acute stage after ECTR.
