Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but also metabolic control. With regard to migratory birds, such metabolic control would have to operate in the individual as well as in the migrating flock as a whole.
PURPOSE: Excessive stool frequency and incontinence after anterior resection (AR) or total colectomy (TC) can be refractory to expectancy and antidiarrheal agents. We prospectively assessed efficacy of anorectal biofeedback therapy (BF) in this clinical situation. METHODS: Thirteen patients (10 men and 3 women; mean age, 62.1 (standard error of the mean (SEM), 4.6) years) had more than six bowel movements per day and/or episodes of incontinence, which did not abate after antidiarrheal agents were given for at least six (mean, 27.9 (SEM, 6.3)) months after surgery. All underwent four sessions of outpatient BF. Assessment was by continence questionnaire and anorectal physiology tests, which were administered before and after BF. RESULTS: In seven AR patients, daily stool frequency was decreased (8.7 (SEM, 2.1) before and 4.6 (SEM, 1.2) after, P < 0.05), and daily incontinence episodes were reduced (2.7 (SEM, 0.9) before and 0.4 (SEM, 0.2) after, P < 0.05) after BF. Six TC patients also had decreased daily stool frequency (6.2 (SEM, 2.1) before, 3.3 (SEM, 1.6) after; P < 0.05) and incontinence episodes (2.4 (SEM, 0.9) before, 0.5 (SEM, 1) after; P < 0.05) after BF. There were no significant changes in anorectal physiology parameters after BF. At a mean follow-up of 10.6 (SEM, 2.5) months after BF, there were no regressions or complications. CONCLUSIONS: BF is a safe and effective option for refractory excessive stool frequency and/or incontinence following AR or TC.
