MATERIAL and METHODS: Ten patients (51.20 ▒10.20 yr.) were assessed three times. The Time Up and Go Test, 12 m Walking Test and Chair Stand Test were used to assess mobility and balance. Purdeu Pegboard and hand writing tests were used to evaluate hand function. The Hospital Anxiety and Depression Scale (HAD) was used to detect depressive symptoms and anxiety score. The Unified Parkinson\'s Disease Rating Scale (UPDRS) and Hoehn &Yahr Scale were also used. The Schwab and England Test was used to evaluate the daily activities (ADL).

RESULTS: The results showed that all the patients' mobility and balance ability improved after surgery (p<0.05). Depressive symptoms / anxiety scores were found to be lower than before surgery (p<0.05). There were differences in terms of ADL and UPDRS scores after surgery (p<0.05). At six month after surgery; depressive symptoms decreased by 78%. ADL and UPDRS motor and total scores improved by 190%, 72%, and 78% respectively.

CONCLUSION: STN DBS is an effective treatment to improve physical functioning, emotional status and daily activities in Parkinson's patients. However, it did not show any positive effect on cognitive function. Keywords : Parkinson's disease, Subthalamic nucleus, Balance, Mobility, Emotional status, Daily living activities
