Effect of Proprioceptive Neuromuscular Facilitation Exercise on Flexibility and Strength of Stroke Patients |
|
| چکیده انگلیسی مقاله |
Purpose: Proprioceptive neuromuscular facilitation (PNF) stretching is considered a clinically effective way to enhace muscle properties, however there is rare information about its effect on muscle flexibility and strength of the patients with stroke.
Objective: To investigate the efficacy of PNF exercise on lower extremity muscle flexibility and strength after stroke.
Methods: Twenty-four males with stroke were chosen for current study and assigned in two groups, PNF (N=12, mean age=59.3) and control group (N=12, mean age=58.7). Both groups received conventional rehabilitation three times weekly over two months, while the PNF group received additional 20 minutes contract-relax method of PNF exercises during each session. Gastrocnemius and hamstring flexibility have been measured pre- and post-intervention by wall lunge and active straight leg raising (aSLR) tests, respectively. Additionally, hamstring and quadriceps strength has been measured pre- and post-intervention by a hand-held dynamometer. A 2 * 2 mixed repeated measure analysis of variance (ANOVA) was utilized for data analysis.
Results: Significant interaction of time x group for hamstring flexibility was found (F= 33.24, P<0.01) and strength (F= 23.86, P<0.01). Post hoc analysis indicated that aSLR (effect size=0.75) and hamstring strength (effect size=0.67) significantly increased in the PNF group. There were no significant interactions or main effects for gastrocnemius flexibility and quadriceps strength.
Conclusion: The findings indicates that eight weeks of PNF stretching improve hamstring muscle flexibility and strength in patients with stroke. However, future researches have to confirm the prolonged effects of PNF exercise. |
