Handgrip strength (HS) and knee extensor muscle strength (KEMS) showed a negative correlation with the Disabilities of the Arm, Shoulder, and Hand (DASH) score at one month following cardiac surgery. We performed a longitudinal study to examine changes in HS/KEMS and DASH score during phase II cardiac rehabilitation (CR) in patients after cardiac surgery. We measured and assessed HS, KEMS, and DASH score in 41 consecutive patients at one and three months following cardiac surgery and examined the relation between these factors at three months following cardiac surgery. Wilcoxon signed-rank test and Spearman correlation coefficients were used to analyze the results. Finally, 26 patients (63.2 years, 73.1% male) were analyzed. There were significant differences from one month to three months following cardiac surgery in HS (26.78 ± 8.26 to 31.35 ± 9.41 kgf, < 0.001), KEMS (1.53 ± 0.42 to 1.72 ± 0.46 Nm/kg, = 0.001), and DASH score (14.76 ± 12.58 to 7.62 ± 9.29, < 0.001). DASH score correlated negatively with HS (r = -0.41, = 0.01) but not with KEMS (r = -0.32, = 0.09) after three months of phase II CR. Although HS, KEMS, and DASH scores changed significantly from one to three months following cardiac surgery during phase II CR, only HS correlated negatively with DASH score at three months following cardiac surgery.
心脏手术后1个月时，握力（HS）和膝伸肌力量（KEMS）与上肢、肩部和手部功能障碍（DASH）评分呈负相关。我们进行了一项纵向研究，以检查心脏手术后患者在心脏康复（CR）II期期间HS/KEMS和DASH评分的变化。我们在41例连续患者心脏手术后1个月和3个月时测量并评估了HS、KEMS和DASH评分，并检查了心脏手术后3个月时这些因素之间的关系。采用Wilcoxon符号秩检验和Spearman相关系数分析结果。最终，对26例患者（63.2岁，73.1%为男性）进行了分析。心脏手术后1个月至3个月，HS（26.78±8.26至31.35±9.41 kgf，<0.001）、KEMS（1.53±0.42至1.72±0.46 Nm/kg，=0.001）和DASH评分（14.76±12.58至7.62±9.29，<0.001）有显著差异。在CR II期3个月后，DASH评分与HS呈负相关（r=-0.41，=0.01），但与KEMS无相关性（r=-0.32，=0.09）。尽管在CR II期心脏手术后1至3个月，HS、KEMS和DASH评分有显著变化，但在心脏手术后3个月时，仅HS与DASH评分呈负相关。
