Postoperative deterioration in muscular function.
To clarify the postoperative fatigue state, we analyzed some components of muscular function before and after surgical procedures. Eleven subjects undergoing elective surgery were studied for test periods of up to 35 days. Significant impairment of muscular functioning, particularly muscle endurance, developed postoperatively. Maximum deterioration was noted on postoperative days 8 and 9. Isometric strength was affected more than isokinetic strength. Changes in muscular functioning in two young volunteers undergoing bed rest were surprisingly similar to those observed in postoperative patients.
