Effect of PNF technique for knee muscles on lower limb performance in subacute stroke – an experimental study

Abstract

Abstract Background: Approximately two-thirds of stroke survivors have sequel of neurological impairments. Although all sequels have direct impact on the performance of activities of daily living, motor deficits of the lower limbs have the most important impact on an individual’s functioning. The objective was to study the effect of proprioceptive neuromuscular facilitation (PNF) technique on lower limb performance in subjects with subacute stroke. Methods: Thirteen participants with subacute strokes were recruited. Participants were treated with PNF rhythmic stabilization technique. All participants received 10 days of intervention. Treatment sessions consisted of PNF rhythmic stabilization exercises for knee that utilizes alternating isometric contractions of agonist and antagonist against resistance. Lower limb performances were measured with Modified Emory Functional Ambulation Profile, Five Time Sit To Stand Test and Postural Assessment Scale For Stroke. Results: Lower limb performances were improved after 10 days of intervention as compared to baseline assessment in all the outcome measures. Conclusions: This study suggests that the rhythmic stabilization technique is an effective method to improve lower limb function that can be used as an adjunct with other therapies.
