Guillain Barre Syndrome (GBS), is the most common cause of acute nontraumatic neuromuscular paralysis in developed countries, is important from the rehabilitation of view since it causes physical and psychosocial problems. The aim of the study was to evaluate clinic features, complications, levels of ambulation and functional improvement and to investigate the progress of GBS patients during rehabilitation. Fourty eight patients, 14 men and 34 women, were entered into the study. Clinical and demographic characterictics, complications, serum calcium-hemoglobin levels and electroneuromyographic findings of the patients are recorded. 6 Point Scale (6PS) and Functional Ambulation Scale (FAS) were used to measure the functional and ambulation levels respectively. The mean duration of disease and rehabilitation are 138.9 days and is 66.2 days respectively. All of the patients had weakness, elevated concentration of protein in cerebrospinal fluid and typical electrodiagnostic features. The other common clinical symptoms are parestesia (%80) and pain (%64.6). The most common complica-tion is pneumonia (%20.8); followed by deep vein trombosis (%16.7) and contractures (%12.5). A significant positive relationship was found between age and 6PS of discharge (P<0.05), and also between the pain and duration of rehabilitation (P<0.05). The relationship between sensory loss and FAS of  discharge was positive and significant (P<0.05). Our results show that necesssity of rehabilitation programmes in reducing the disability and enhancing freedom and the importance of coping with pain in reducing total rehabilitation time in patients with GB
