Abstract: Objective: To observe the effects of the intensive training of work ability on upper extremity function after operation of hand trauma.Methods: Seventy patients with hand injury after operation were randomly divided into the control group and observation group.The control group was treated with routine rehabilitation.The observation group was additionally trained with the intensive training of work ability on the basis of routine rehabilitation therapy.The contents included building,electrician,repair,transportation,secretary and driving workstations training.The training time in each workstation was 30 min,six workstations training was completed every day,one time every workstation for 12 weeks.The related rehabilitation in two groups was evaluated before and after rehabilitation training.The motor function,emotional function and activity of daily living(ADL) were evaluated using Fugl-Meyer assessment(FMA),Hamilton Depression Scale(HAMD) and modified Barthel index(MBI) or FIM,respectively.Results: The difference between the scores of all items in the two groups before treatment was not statistically significant(P>0.05),the scores of all items in the two groups were significantly improved after treatment(P<0.01),and the scores of all items of patients in the observation group after treatment were significantly better than those in the control group(P<0.01).Conclusions: The early postoperative occupation rehabilitation intervention has important clinical significance in the recovery of upper limb dysfunction caused by hand injury.
