[ investigation of the effect of rehabilitation program on the spastic diplegia patients' oxygen pulse and aerobic capacity]

ABSTRACT

Despite the voluminous amount of studies in the field of exercise sciences over the past three decades, there remains a paucity of information on the activity patterns and physiological responses to exercise in people with disability. The aim of this study was to investigate the effect of an exercise-rehabilitation aerobic program on the cardiovascular fitness, maximal oxygen uptake [VO[2 max]] and oxygen pulse for children with spastic cerebral palsy [Diplegia] and their comparison with healthy children. The experimental group for this semiexperimental study comprised of 18 [10-14 years old] diplegic spastic cerebral palsy children [CP] with average height [131 +/- 6.34 cm] and weight [29.83 +/- 5.64 Kg] selected with the consent of their parents as well as specialist physician. Eighteen normal children were randomly designated as the control group. The variables of the experimental group were measured before and after the exercise-rehabilitation program according to Mac Master protocol on cycle ergometer at the laboratory conditions. Then these values were compaired with those of the control group. The experimental group performed exercise program for a period of three months, three times a week with intensity average 144 bpm of heart rate. Each session lasted 20-25 minutes for each subject. The exercise-rehabilitation program led to enhancement of the maximal oxygen uptake [VO[2 max]] at the patient group. The oxygen pulse [VO[2]/HR] of the patient group was significantly lower than that of the normal group and the exercise program improved this variable [p<0.05]. This study indicated that in the spastic patients the lack of activity and being sedentary for a long time increases spasticity, the involuntary movements lead to a decrease in cardiovascular fitness and aerobic capasity and an increase in energy cost during exercise or daily activity as compared with normal people. The Rehabilitation program and exercise, even for short time or at low intensity leads to an improvement in the variables under study and enhances cardiovascular efficiency in these patients
