The aim of this study was the comparison of efficacy of two nonsurgical
   methods in management of patients with acute ligamentous injury (Sprain)
   of ankle which are “Primary immobilization” and “Early active functional
   treatment”.

          This study consist  of 200 patients with acute ankle sprain who referred to
   emergency ward and clinic of orthopedics of Mobasher Kashani Hospital of
   Hamadan. This was a clinical trial study. 100 patients were managed with
   primary immobilization and the other 100 patients were treated with active
   functional treatment. Information were gathered with a questionaire that
   complete during a primary and later serial physical examinations. Datum
   were  analyzed manually and then for quantitative   variables, t-test and for
   gualitative  variables, fisher exact test were performed.

          Results of this study revealed that the mean time for return to normal
    daily activities in patients with grade I of ankle sprain that managed with
   “primary immobilization” was14.5 days Vs 14.1 days in patients that managed
   with “early   active functional treatment”.  In  addition   , the mean time for
   return to professional or athletic activities, in  patients with grade I and  II of
   ankle sprain in two groups had not a significant  difference. But the mean
   time for return to normal daily activities in patients with grade II of ankle
   sprain with “primary immobilizatin” and “early active functional treatment”
   were 27.4 and 21.38 days respectively. In two groups there was no
   difference in level of fuctional activity on 90 days after treatment.

          Finally we could say that there was no difference between these two
   methods in approaching the patients to their pre-injury level of activity.
