The effects of an exercise program on patients after cardiac surgery were studied. The physical status and length of hospitalization of 44 patients who were not exposed to the program (group I) were compared with those of 43 program participants (group II). All patients were evaluated preoperatively and before hospital discharge. Whereas 24 of the patients in group I scored lower at discharge than preoperatively on an assessment of functional activity, only 9 from group II did so (p = 0.001). Fewer patients in group I than in group II increased their performance in a test of distance walking. Patients in group I lost significantly more (p = 0.03) range of motion in upper and lower extremities than did patients in group II. The mean length of hospitalization for patients in group II was shorter than for those in group I by 1.9 days (p less than 0.001). In summary, the exercise program reduced the prevalence of activity morbidity incident to hospitalization for cardiac surgery, and was associated with a reduced length of stay.
研究了运动计划对心脏手术后患者的影响。将44名未参加该计划的患者（第一组）的身体状况和住院时间与43名计划参与者（第二组）进行了比较。所有患者在术前和出院前均接受了评估。在功能活动评估中，第一组中有24名患者出院时的得分低于术前，而第二组中只有9名患者如此（p = 0.001）。在距离行走测试中，第一组中提高成绩的患者比第二组少。第一组患者上下肢的活动范围损失明显多于第二组患者（p = 0.03）。第二组患者的平均住院时间比第一组患者短1.9天（p小于0.001）。总之，运动计划降低了心脏手术住院期间活动发病率的发生率，并与住院时间缩短有关。
