| Objective: The research group clinically found that applying digital sensory stimulation to the upper limbs on the hemiplegic side of stroke patients can immediately and significantly reduce the spasm of the flexor muscles of the affected fingers,and promote their active finger extension.To investigate the effect of digital sensory stimulation on motor function of upper limbs in stroke patients with hemiplegia.Methods: A total of 40 stroke patients who met the criteria of admission and row were enrolled and randomly divided into a treatment group and a control group with20 cases in each group using a random number table.Among them,the control group only received conventional rehabilitation treatment,including conventional drugs,conventional rehabilitation nursing,etc.;on the basis of conventional rehabilitation,in the treatment group,the researchers performed the treatment on the nail bed,distal phalanx end and both sides of each finger of the upper extremity of the patient with hemiplegia.Stimulation,the intensity of stimulation is the minimum intensity that can cause active finger extension without significant pain,each stimulation lasts 2-5s,and the interval between two stimulations is 5-10 s.Patients in the treatment group are treated 3 times a day,6 days a week.Both groups received rehabilitation therapy for 3weeks.The Fugl-Meyer Motor Function Evaluation Scale（FMA-UE）and Modified Barthel Index（MBI）were evaluated in the two groups before and after treatment;the modified Ashworth Muscle Spasm Scale（MAS）was used to evaluate the hemiplegia of the two groups before treatment and after 3 weeks of treatment Lateral flexor pollicis brevis,superficial flexor digital,extensor digital,biceps,triceps muscle tension;and surface electromyography（s EMG）was used to collect the maximum isometric contraction（MIVC）of the above muscle groups on the hemiplegic side The surface EMG signal was processed by the system to take the root mean square value（RMS）.Results: 1.Before treatment: There were no differences in FMA-UE score,MBI score,flexor pollicis brevis,flexor digitorum superficialis,extensor digitorum,biceps,triceps RMS and MAS grade on the hemiplegic side between the two groups,that is comparable（P>0.05）.2.After 3 weeks of treatment:（1）The FMA-UE scores of the two groups were significantly improved compared with those before treatment（P<0.01）,and the FMA-UE scores of the treatment group were improved more significantly than those of the control group（P<0.01）.（2）The MBI scores of the two groups were significantly improved compared with those before treatment（P<0.01）,and the MBI scores of the treatment group were improved more significantly than those of the control group（P<0.01）.（3）The RMS of superficial flexor digital,extensor digital and triceps muscle in the treatment group were higher than those before treatment（P<0.05）;The extensor RMS was improved compared with before treatment,but there was no difference（P>0.05）.In the other two groups,the difference of RMS of digital extensor and triceps before and after treatment was statistically significant（P<0.05）.（4）The RMS values of flexor pollicis brevis and biceps brachii in the two groups were improved compared with those before treatment（P<0.05）;there was no significant difference in the RMS values of flexor pollicis brevis and biceps brachii between the two groups before and after treatment（P>0.05）.（5）The muscle tension levels of upper limbs in the two groups were improved compared with the previous ones,and there were statistical differences in flexor pollicis brevis and biceps brachii before and after treatment（P<0.05）.The muscle tension levels of the extensor finger and triceps in the two groups showed a downward trend after treatment,but there was no statistical difference（P>0.05）.There was a statistically significant difference in the muscle tension grade of the superficial flexor muscles between the two groups before and after treatment（P<0.05）,and there was no statistical difference between the two groups after treatment（P>0.05）.Conclusion:1.On the basis of routine rehabilitation,combined finger sensory stimulation can improve the strength of the extensor finger and triceps muscle of the upper limbs of hemiplegic patients with stroke,and reduce the spasm of the flexor pollicis brevis and biceps brachii,which is beneficial to the affected side.Recovery of upper limb motor function and improvement of activities of daily living.2.Finger sensory stimulation can be used as a treatment method to restore upper limb motor function after stroke,and its safety,effectiveness and simplicity are worthy of clinical rehabilitation. |
