Purpose: The purpose of this study was to examine the effects of resistant gait training with proprioceptive neuromuscular facilitation (PNF) on the walking and balancing abilities of chronic stroke patients.
Methods: Twelve chronic stroke patients were randomly assigned to either a control group (n = 6) that underwent treadmill gait training or an experimental group (n = 6) that underwent resistant gait training using PNF. The interventions were performed five times per week for four weeks. Gait variables were measured using a GAITRite system (CIR System Inc, Clifton, NJ, USA) to examine changes in walking ability; the Berg balance scale (BBS) was used to measure changes in balance; and the activity-specific balance confidence scale (ABC) was measured to examine changes in confidence about balance. A Wilcoxon signed-rank test was used to examine intragroup differences before and after the interventions, and a Mann-Whitney U-test was used for intergroup comparisons of the effects of the interventions. All statistical significance levels were set to α=0.05.
Results: Both the experimental group and the control group showed significant intragroup improvement in walking speed, the number of steps per minute, stride length, double support time, balance, and confidence about balance after the interventions (p < 0.05). In intergroup comparisons after the interventions, the experimental group showed significant improvements over the control group in walking speed, the number of steps per minute, stride length, balance, and confidence about balance (p < 0.05). No significant difference in double support time was seen in the intergroup comparison after training (p > 0.05).
Conclusion: This study applied resistant gait training using PNF to chronic stroke patients, and the results showed significant improvements in the patients' walking and balancing abilities. Therefore, resistant gait training using PNF is thought to be applicable as an intervention method for chronic stroke patients.
