ObjectiveTo compare the clinical effects of early dynamic brace passive activity program and average delay activity program after the repair of extensor tendon. MethodsSeventy-eight patients undergoing repair of the extensor tendon during the period from December 2008 to October 2011 in our hospital were randomly divided into two groups.The treatment group had 36 patients who were treated with early dynamic brace passive activity program,and the other 42 patients belonged to the control group and they accepted delay activity program.TAM and FIM were used to evaluate their clinical effects six and eight weeks after surgery,respectively. ResultsThe results of TAM and FIM of the treatment group were significantly better than those of the control group (P<0.01). ConclusionThe early dynamic brace passive activity after extensor tendon injury repair can improve the clinical effect and is worth popularizing.
