Postoperative deterioration in muscular function
H. Edwards, E. A. Rose and T. C. King
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.
