Effects Of Variable Frequency Vibration Therapy During Sitting Antispasmodic Postures On Motor Function Of Spastic Upper Limb

Background and ObjectiveSpasticity is one of the common complications of patients with hemiplegia after stroke.The incidence of upper extremity flexor spasm is about 40% in the onset of 3 months,which directly affects the motor function of the patient and the exercise of daily life,and gives the patients,family members or nursing workers a lot of inconveniences.Severe problems can also lead to physical pain,shortened muscle fiber length,degenerative joints and other problems.It is an important factor and a rehabilitation difficulty that affects the functional recovery of upper extremities after stroke.In recent years,vibration therapy has been studied as an adjunct to the treatment of upper extremity flexor tendons in patients with stroke.However,the target of treatment is mainly the spastic muscle itself,and the vibration frequency is a fixed frequency.In this study,variable frequency vibration therapy was used,and the effect of vibration therapy during sitting antispasmodic postures on spasticity and motor function of upper limb in patients with stroke was observed.Subjects and Methods1.Subjects selection: 30 stroke patients with hemiplegia who were treated at the rehabilitation center of the Fifth Affiliated Hospital of Zhengzhou University from April 2016 to April 2017 were randomly divided into the treatment group and the control group,15 cases in each group.2.Treatment methods: The control groups were given routine rehabilitation training,including active and passive activities of each joint of the limb,nerve promotion techniques,occupational therapy,sitting balance training body position transfer training,standing balance training,and walking training,etc.The treatment group received variable frequency vibration therapy during sitting antispasmodic postures on the basis of routine rehabilitation intervention.The vibration frequency is(6±3)Hz for a total of 4 weeks.3.Evaluation of therapeutic effects: To assess spasticity,motor function,and abilities of activities of daily living by MAS,RMS,A-ROM,FMA and MBI before and after 4 weeks treatment.ResultsAfter 4 weeks treatment,the scores of MAS,A-ROM,RMS,FMA and MBI improved in the both groups compared to those before treatment(P<0.05),and the treatment group was better than the control group(P<0.05).Conclusions1.The variable frequency vibration therapy during sitting antispasmodic postures is more effective than conventional rehabilitation alone in relieving spasticity and improving motor function,and abilities of activities of daily living of the hemiplegic upper limb in stroke patients.2.For the improvement of motor function of spastic upper limb in patients with stroke hemiplegia,combined with variable frequency vibration therapy under specific posture,this therapy is worthy to applicating and promoting in clinical works.
