Abstract
Purpose: The study examined the effects of the proprioceptive neuromuscular facilitation pattern exercise and protein intake on balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly.
Methods: A total of 30 elderly people (65∼74years) with sarcopenia were recruited and randomized to Group I (n=10), Group II (n=10), and Group III (n=10). Their balance ability was measured using the functional reach test. Group I performed the proprioceptive neuromuscular facilitation pattern exercise and protein intake. Group II performed the proprioceptive neuromuscular facilitation pattern exercise. Group III performed protein intake. Their gait ability was measured using the Timed Up and Go test. Lower extremity muscular strength was measured using the Five Times Sit to Stand test.
Results: As a result of comparison within groups, Group I and Group II showed a significant difference in balance, gait, and lower extremity muscular strength after the experiment (p<0.05), and Group I showed a more effectively significant difference than either Group II or Group III in balance, gait, and lower extremity muscular strength before and after the experiment (p<0.05).
Conclusion: This study showed that the proprioceptive neuromuscular facilitation patterns exercise and protein intake was effective in balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly.
