General practitioner, Valieasr Hospital, Birjand Abstract Background: Recognition of Clinical factors associated with disability of stroke patients is important, because they can affect the prognosis and future recovery following rehabilitation. Materials and methods: Consecutive stroke patients admitted in Valie-Asr hospital of Khorasan enrolled in a prospective study in 2005. Hemihyposthesia, hemianesthesia, hemineglect and homonymous hemianopsia were evaluated in the patients. Disability score was determined based on the Rankin scale at 72 hours post stroke. Mean of Rankin Disability Score (MRDS) was analysed by T and Fisher tests and p<0.05 regarded as significant. Results: 329 stroke patients were investigated. Hemihyposthesia, hemianesthesia, hemineglect and homonymous hemianopsia were found in 37.4%, 13.8%, 7.9% and 7.3% respectively. MRDS was significantly higher in patients with hemianesthesia than other stroke patients, p<0.001. MRDS of patients with each of hemihypoestheisa, hemineglect and homonyous hemianopsia was not significantly different than patients without these abnormalities, p=0.44, p=023 and p=0.83 respectively. Patients with triad of hemianesthesia, hemineglect and homonymous hemianopsia had significantly higher MRDS than others, p<0.001. Conclusion: Hemianesthesia is the most important clinical causative factor of MRDS of the stroke patients. Presence of above triad predicts the highest MRDS in these patients.
