Research The Effect Of Nerve Muscle Electrical Stimulation On Muscle Tension And Muscle Strength Of Upper Limb With Stroke Patients

Objective: to research the effect of nerve muscle electrical stimulation (NMES) onmuscle tension and muscle strength of upper limb with stroke patients.Methods: Choose50stroke patients who can meet the stroke’s selected standard wererandomly divided into treatment group and control group, each25cases. The treatmentgroup gives NMES treatment based on conventional rehabilitation treatment, and controlgroup only conventional rehabilitation treatment. Conventional rehabilitation includedoccupational therapy, massage and physical therapy. Nerve muscle electrical stimulationtreatment takes as follows: A group of electrode placed in supraspinatus and central deltoidmuscle. Current triangle wave wide is800ms, t rises500ms, t falls300ms, frequency0.2Hz, electricity50-75s, power off3-5s, daily treatment one time, every treatment25min,4weeks for one period treatment. It is given muscle tension and muscle strength evaluationsbefore treatment, the first week, the second week, the third week and the forth week aftertreatment in the two groups respectively. The evaluation of bicipital muscle tension adoptedAshworth classification method, the evaluation of triceps muscle strength adopted Lovettclassification method to precede standard evaluation.Results:1. There was significant improvement of the bicipital muscle tension between treatmentgroup and control group in the first, second, third and forth treatment weeks, especiallysignificantly shown in control group.（p<0.01）.2. There was no statistically significant of the triceps muscle strength difference oneweek after treatment in two groups (p﹥0.05), but it was obvious differences in musclestrength during the treatment of the second weeks, the third weeks, the fourth weeks intreatment group（p<0.01）.3. There were obvious difference in the muscle tension improved percentage in the firstweek, second week and third week after treatment between two groups（p<0.01）. But in thefourth week there was no statistically significant difference of the muscle tension improvedpercentage rate in the two groups（p﹥0.05）;it was shown that signicant differences ofmuscle strength improved percentage between two gruops. Conclusions:1. The nerve muscle electrical stimulation has effective for the upper limb after strokein improving flaccid paralysis muscle tension but inhibiting hypermyotonia.2. The nerve muscle electrical stimulation has effective for the upper limb after strokein improving muscle strength.3. The effectiveness to muscle tension and muscle strength of the upper limb afterstroke seemed that nerve muscle electrical stimulation was an effectiveness method offunctional rehabilitation.
