Overview
Postural instability is one of the cardinal signs in Parkinson's disease (PD). It represents one of the most disabling symptoms in the advanced stages of the disease. It is associated with frequent falls and loss of independence. The aim of the current study is to assess the long term efficacy of high frequency repetitive transcranial magnetic stimulation (rTMS) on improving postural instability in PD patients.
Description
Thirty to forty PD patients will be recruited who fulfill the U.K Parkinson's Disease Brain Bank Criteria for idiopathic PD. Patients with mild to moderate disease severity according to UPRS and Modified Hoehn and Yahr staging, age ranged from 55-70 years, duration of illness from two to five years will be included. The patients who will match our inclusion criteria will be assigned randomly into two equal groups; control group (G1) will receive a designed physical therapy program and study group (G2) will receive 12 sessions of (5Hz) rTMS over the primary motor cortex in addition to the same physical therapy program as in G1. The treatment will be conducted three times per week, over four weeks.
Biodex balance system will be used to assess objectively balance indices (overall, anterio-posterior and medio-lateral balance index) and dynamic limit of stability (overall LOS score, time to complete test) pretreatment , posttreatment and one month later as a follow up.
