Abstract |
INTRODUCTION Postural instability in patients with Parkinson's disease(PD) is most incapacitating symptom which can put patients at increased risk for falls and death. Although there were many reports about various physical interventions that can be performed on PD patients, few study groups have paid attention to the effects of vestibular rehabilitation as a treatment. The aim of this study is to assess effectiveness of vestibular rehabilitation in improving postural instability in patients with PD. METHOD Thirty patients diagnosed with idiopathic PD at a high risk of falls were enrolled based on their scores on the timed up and go test. General rehabilitation therapy was performed on PD patients using Hamid's exercise in the period of 12 weeks. They were asked to complete questionnaires including verbal analogue scale (VAS), activities specific balancing confidence scale (ABC) for the functional aspect before and after the treatment. Quantification of improvement was conducted utilizing static posturography and Sensory Organization Test (SOT) of Computerized Dynamic Posturography (CDP). Statistical significance was tested in between the patients before and after treatment by t-test. RESULT There was a statistically significant improvement in body sway, scores of VAS and ABC. The spectral frequency analysis of body sway showed a significant decrease in spectral power at low frequencies which means a significant improvement of proprioception after the treatment. The patients showed a significant improvement in the follow-up CDP (p<.05). CONCLUSION The results showed that vestibular rehabilitation is effective in improving postural control in individuals of PD, and further the activities of daily life, as well as in reducing the risk of falls. |
