RESUMO
Fatigue is among the most common symptoms of multiple sclerosis. Hence, exercise is recommended to multiple sclerosis patients. This research has been conducted to compare of stretching with aerobic and aerobics exercises on fatigue levels in patients. In this experimental study designed as a clinical trial, 80 eligible patients with multiple sclerosis referred to MS society in Tehran were selected according to inclusion criteria and then were randomly divided into two groups [stretching with aerobic and aerobics]. The data gathering tool was a questionnaire consisted of two parts. The first part contained demographic characteristics, and the second part included fatigue severity scales [FSS]. Exercises were done for 18 sessions and the exercise execution and period were assessed using a checklist. Data were analyzed using chi-square, paired and independent t-tests, and analysis of covariance. There were significant difference between the two groups in pretest fatigue level [p<0.005]. Analysis of covariance showed that the mean of posttest fatigue level was significantly different between stretching with aerobic and aerobics groups and before-intervention fatigue severity was moderated [p=0.001]. According to the findings of this research, both aerobic and stretching exercises are effective in reduction of fatigue in the multiple sclerosis patients. However, stretching with aerobic exercise is more effective in the decrease of fatigue
