Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.
