Improvement activity evaluation after occupational therapy in stroke patients using hurdle model for longitudinal data

stroke is prevalent among adults. The fall is most common balance and motor impairments that affect the quality of life in stroke patients. this study was performed with aim of investigate the factors affecting the motor recovery in stroke patients treated with occupational therapy and predicted balance status in patients with a hurdle regression model. In a longitudinal study of 9 months with not at random access sampling for a total of 30 stroke patient the score test of balance measured every two weeks. Because of many zero in number of fall, regression Hurdle model was fitted to data using Sas Software version 9.2. The frequency of falls in women is more than men. The relative performance improvement was achieved with a minimum of 50 sessions. Stroke duration and Length of follow up patient were significantly improved motor function in stroke patients) p<0.05(. the odds of motor improvement in patients with chronic phase is 10 percent less than odds of patients with the acute phase. with considering the factors involved in the promotion of motor function and doing interventions combination with occupational therapy to prevent falls in stroke patients specially in women with chronic phase that were at higher risk of falls can be ventured to fast recover this group of patients to the community.
