Studying the clinical and electrophysiological mechanisms of the short term effects of local plantar vibration on balance in patients with chronic stroke(pilot study)

Explanation of the possible effects of local vibration of the soles of the feet on different systems affecting balance

Before and after intervention study, one intervention group, 12 patients, sample size with non-parametric Wilcoxon test

first session Patients visit the clinic and fill in the consent form and information questionnaire, balance assessment by mini-best test, assessment of spasticity (MMAS) and plantar surface sensation (SWMF) and range of ankle dorsiflexion, recording of Hoffman's reflex, application of vibration for 5 minutes with 100 Hz frequency, 3 middle sessions of vibration application based on the patient's choice, it is done in the form of a home visit at home or a visit to the clinic in person, the last session (fifth) visit the clinic in person and apply vibration and repeat all the evaluations of the first session

Criteria for entering the study: ● Diagnosis of stroke by a neurologist ● At least 3 months have passed since the last stroke ● Suffering from stroke-induced balance disorder based on the one-leg standing test (the patient's inability to stand on the more involved leg for 30 seconds with eyes open) Criteria for not entering the study: People who were undergoing other treatments to improve balance The presence of any other neurological disease, other than stroke, that leads to balance deficits (such as Parkinson's and cerebellar injuries, etc.)

The local vibration of the soles of the feet with a frequency of 100 was applied for 5 minutes and in 5 sessions every other day
