Effects of an exercise program on the rehabilitation of patients with spinal cord injury.

OBJECTIVES: To evaluate the impact of directed physical exercise in patients with spinal cord injury (SCI) and to measure functional independence before and after an exercise program. DESIGN: Case series. SETTING: Tertiary care center. PARTICIPANTS: Thirteen volunteers with thoracic SCI. INTERVENTION: Patients participated in a 16-week exercise program, consisting of 3 weekly 120-minute sessions. They performed mobility, strength, coordination, aerobic resistance, and relaxation activities. MAIN OUTCOME MEASURES: The FIM instrument, arm crank exercise test, wheelchair skills, maximum strength, anthropometry (body composition measurements), and lipid levels. The results were processed by using nonparametric statistical tests. RESULTS: After comparing the values at the beginning and end of the program, patients showed a significant increase in the following parameters: average FIM score (p < .001) 113 +/- 7.1; weight lifted in the bench press exercise (46%, p < .0001), military press (14%, p < .0002), and butterfly press exercise (23%, p < .0001), and number of repetitions for biceps (10%, p <.0001), triceps (18%, p < .0001), shoulder abductors (61%, p < .0001), abdominals (33%, p <.009), and curl back neck exercise (19%, p < .0001). The maximum resistance achieved during the arm crank exercise test increased (p < .001), and heart rate 6 minutes after the exercise test decreased (p <.05). The time required for the wheelchair skill tests significantly decreased in all the tasks. No statistically significant changes occurred in body weight (p < .154), percentage of body fat (p < .156), lean body weight (p < .158), cholesterol/high-density lipoprotein cholesterol ratio (p < .076), or maximum heart rate (p < .20). The only complication arose in a patient who developed transient sinus bradycardia and hypotension after the arm crank exercise test. CONCLUSION: The directed exercise program had a positive impact for most of the variables of the study.

Exercise and physical activity of adolescents.

Multiple studies point toward the beneficial role of regular exercise in preventing cardiovascular disease. The purpose of this study is to determine the prevalence of physical activity and exercise among adolescents from the only high school in Cataño, Puerto Rico. An open-ended, multiple choice questionnaire was administered to 106 students who were randomly chosen. Questions included frequency of exercise, type of sports which they practiced and would like to practice. Results were statistically analyzed. The study revealed that 53% of the participants did not exercise regularly, exercising less than once a week. Those who did exercise were involved in a competitive team sport (35% of females: volleyball; 65.8% of males: basketball). Approximately 1/3 of the females and of the males replied they would like to practice noncompetitive sports which should be incorporated into their lifestyles through early intervention in the school, home and through the primary care physician.

In vivo release of enkephalin from the globus pallidus.

Push-pull cannulae were acutely positioned through previously implanted guides in the globus pallidus of unanesthetized freely moving cats and rats. During slow-flow perfusions, enkephalin release was detected in resting conditions and increased more than 3-fold when both 50 mM K+ and 1.8 mM Ca2+ were present in the perfusing medium. Local perfusion with veratrine also enhanced enkephalin release. Furthermore, in vivo, electrical stimulation of the rat caudo-putamen enhanced enkephalin release in the pallidum. This latter finding is consistent with a functional strio-pallidal enkephalin-containing pathway previously postulated by immunohistochemical or lesion experiments.
