The Effect of a Stepwise PNF Pattern Therapy in Weight-Bearing Positions on the Balance and Walking Functions of a Patient with Subacute Stroke -A Single Case Study-

Abstract

Purpose: The purpose of this study was to demonstrate the effects of a stepwise proprioceptive neuromuscular facilitation (PNF) pattern therapy in weightbearing positions on the balance and walking functions of a patient with subacute stroke. Methods: The patient was a 78-year-old man with right post-stroke hemiparesis who had decreased balance and gait function. During the baseline and withdrawal phases, no intervention was applied; however, in the intervention phase, the patient received a stepwise PNF pattern therapy in weight-bearing positions. Results: During the intervention phase, the LOS improved by 296.51% (from $2482.13mm^2$ to $626mm^2$), and walking speed improved by 18.70% (from 0.75 m/s to 0.64 m/s). The LOS and 10MWT values appeared to be clinically significantly improved after the intervention. In addition, the scores of the BBS and ABC scales improved by 100% (from 36 points to 18 points) and 56.52% (from 720 points to 460 points), respectively. Conclusion: These findings suggest that a stepwise PNF pattern therapy may be helpful in enhancing the balance and walking function of a patient with subacute stroke. Further studies are required to validate the results of this study.
