Each patient was evaluated at the end of first and second month after thebaseline evaluation. Patients were divided into two groups. Those in the first andthird week were put in the exercise group and second and fourth week in the controlgroup. Patients in the exercise group (n 0/15) were given a schedule of exercises toundertake at home; the others (n 0/15) did not receive this instruction.Measures: Ten- and 20-m walking test, first pace length, pace number in 10 m,walking around a chair, Nine Hole Peg Board (NHPB) test.Results: Following the home exercise programme, patients in the exercise groupshowed improvement in walking 10 and 20 m, time elapsed to complete walkingaround a chair and length of the first pace length, and in the motor performance ofboth hands (p B/0.001).Conclusions: A home-based rehabilitation programme for patients with Parkinson’sdisease helped to improve motor performance compared to patients who did nottake advantage of a regular, professionally designed exercise programme.Introduction tional activity disorders may arise due to loss of trunk mobility and postural reflex, which mayParkinson’s disease (PD) is a neurological disorder also result in dependency in activities requiringcausing loss of functional abilities and progressive manipulation and skill, especially in the earlyloss of independence despite medical treatment.1 Á 3 stages.4 Á 7 Progressive bradykinesia and hypokine-Depending on the severity of the disease, func- sia result in difficulty in performing daily activities.
