Objective: The aim of our study is to investigate the effects of home exercise program on balance, postural control, coordination and functional strengthening in parkinsonian patients. Methods: The study was consisted of idiopathic Parkinson's disease patients, who were not given any exercise training previously. The program including stretching, strengthening, coordination and balance exercises was structured according to the severity of disease. The patients were taught the exercises by a physiotherapist and in addition, were given an illustrated annotated leaflet for home program. Patients were asked to perform the exercises 2 times a day, with 10 times repetitions, for 12 weeks. The static and dynamic balance capacities (Berg Balance Scale-BBS, functional reach test), timed performance capacity (timed up&go test, sit to stand test) of the patients were evaluated before the exercise training. The stage of the disease was evaluated using Modified Hoehn-Yahr Parkinson's Disease Staging, also the severity of the disease was assessed using the United Parkinson's Disease Rating Scale (UPDRS) motor score and the activities of daily living were measured using the Schwab and England Activities of Daily Living Scale. All assessments were repeated following the 12-week exercise program. Results: The mean age of the parkinsonian patients, who completed the exercise program, was 68.34 + or - 8.92 year (51-88) and the mean duration of disease was 4.94 + or - 4.25 (1-20) year. A significant increase in the scores of BBS, functional reach test (both forward and backward), and a significant decrease in the score of single timed chair-rise test were observed following the home exercise program. A significant improvement was observed in the scores of the Schwab England Activities of Daily Living Scale (p<0.05). Conclusion: Home exercises enhance the balance abilities and provide improvement on activities of daily living of Parkinson's disease patients. Therefore, besides the medical treatment, exercise programs should be included in the treatment of Parkinson's patients.

Yontemler: Calismaya daha once egzersiz egitimi verilmemis idyopatik Parkinson hastalari alindi. Egzersiz programi, hastaligin siddetine uygun olarak secilmis germe, kuvvetlendirme, koordinasyon ve denge egzersizlerini icermekteydi. Egzersizler fizyoterapist tarafindan hastalara ogretildi ve ayrica resimli ve aciklamali olarak ev programi seklinde verildi. Hastalardan egzersizleri gunde 2 kez, 10 tekrarli olarak ve 12 hafta boyunca yapmalari istendi. Hastalarin egzersiz egitimi oncesi statik-dinamik dengeleri (Berg Denge Olcegi, Fonksiyonel uzanma testi) ve sureli yurume, sandalyeye oturma, oturmadan ayaga kalkma aktivitele-riyle sureli performanslari degerlendirildi. Hastalik evresi modifiye Hoehn-Yahr evrelemesi, hastalik siddeti Birlesik Parkinson Hastaligi Degerlendirme Olcegi (BPHDO) motor skoru, gunluk yasam aktiviteleri Schwab England Gunluk Yasam Etkinlikleri Olcegi ile degerlendirildi. Tum degerlendirmeler 12 haftalik egzersiz programindan sonra tekrarlandi. Bulgular: Egzersiz programini tamamlayan 29 Parkinson hastasinin yas ortalamasi 68.34 + or - 8.92 yil (51-88) ve hastalik baslangic suresi 4.94 + or - 4.25 (1-20) yil idi. Hastalarin ev egzersiz programi sonrasinda Berg Denge Olcegi (BDO) skorlarinda, one ve arkaya fonksiyonel uzanma testinde anlamli artis ve sureli performans testlerinden olan sandalyeden bir kez ayaga kalkma testinde anlamli azalma saptandi. Schwab England Gunluk Yasam Aktiviteleri Olcegi skorlarinda anlamli duzelme gozlendi (p<0.05). Sonuc: Parkinson hastaliginda ev egzersizleri hastalarin denge yeteneklerini duzeltmekte ve gunluk yasam aktivitelerinde iyilesme saglamaktadir. Bu nedenle Parkinson hastalarinin tedavisinde medikal tedavilerin yani sira egzersiz programlari da mutlaka yer almalidir.
