Effect of core strengthening with pelvic proprioceptive neuromuscular facilitation on trunk, balance, gait, and function in chronic stroke

The purpose of this study was to evaluate the effects of core strengthening combined with pelvic proprioceptive neuromuscular facilitation (PNF) on trunk impairment, balance, gait, and functional ability of chronic stroke patients. Twenty-three participants with chronic stroke were recruited and randomly allocated to one of the two groups: core strengthening combined with pelvic PNF (group 1, n=13), and pelvic PNF with trunk flexibility exercises (group 2, n=10). Intervention was given to both groups for 60 min per session 5 times per week for 4 weeks. Performance of both groups was evaluated on Trunk Impairment Scale, Tinetti Performance Oriented Mobility Assessment (Tinetti-POMA), Balance Evaluation Systems Test (Mini-BESTest), Wisconsin Gait Scale, and Barthel Activities of Daily Living Index prior to and after the completion of the intervention. The comparison between postintervention scores of Tinetti-POMA between group 1 (18.76±1.78) and group 2 (16.8±1.87) and Mini-BESTest group 1 (16.15±1.28) and group 2 (14.7±1.41) showed significant difference (P=0.018). The results indicated that core stabilisation combined with pelvic PNF was more effective for improving trunk impairment, balance and gait of chronic stroke patients.
