Objective To observe the effect of iliopsoas tensile vibrationtraining on the walkingability of strokesurvivors.Methods Thirty strokesurvivors were randomly divided into an observation group and a control group,each of 15.Both groups were given traditional rehabilitationtreatment,while the observation group was additionally provided with iliopsoas tensile vibrationtraining.Both groups were evaluated in terms of the root mean square (RMS) of iliopsoas,active range of motion (A-ROM) of the hip joint,the kinematic parameters of gait and Berg balance scale (BBS) scores before and after the 4-week treatment.Results Before the treatment there were no significant differences between the two groups in any of the measurements.After the treatment improvement in all of the measurements was observed in both groups,with the average RMS iliopsoas,A-ROM,step length,step velocity and BBS score of the observation group significantly better than those of the control group.Conclusions Tensile vibrationtraining of the iliopsoas can significantly improve the muscle excitability of the affected iliopsoas in strokesurvivors,and improve their balance and walkingability.
