Objective: This study aimed to determine the effect of proprioceptive neuromuscular facilitation (PNF) balance exercise on the ability to balance and walk in patients with hemiplegia caused by stroke.
Design: A randomized controlled trial
Methods: Following baseline measurements, patients (n＝24) with hemiplegia caused by stroke were randomized into two groups: the PNF balance group (n＝12) that received PNF balance exercise and the balance group (n＝12) that received general balance exercise. Each group joined the intervention for 30 minutes, 5 times per week for 6 weeks. Both groups performed the Timed Up and Go test (TUG) and Berg Balance Scale (BBS) for balance, as well as the 10-meter walking test (10MWT) and 6-minute walk test (6MWT) for walking. The data were collected both before and after the intervention. The paired t-test was used to compare the post-intervention changes compared with pre-intervention data. An independent t-test was used to analyze the differences in the dependent variables between the two groups.
Results: After the 6-week intervention, both groups showed significant improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) parameters (p<0.05). The patients in the PNF balance group showed greater improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) than those in the balance group (p<0.05).
Conclusions: PNF balance exercise shows improvements in balance and walking parameters in patients with hemiplegia caused by stroke.
