ABSTRACT
Objective To analysis the consequence of current perception threshold (CPT) by different frequency and time of transcutaneous electrical nerve stimulation (TENS). Methods CPT of foramen area and arm area was measured to evaluate the effect of TENS. Different frequency and time of TENS was given to 30 healthy volunteers. Stimulating to Hegu, CPT of the foramen area and the arm area on the same side was measured. Results CPT of the foramen area increased with stimulation. Low frequency of TENS inhibited the chronic pain significantly(P＜0.05),high frequency of TENS inhibited both of the chronic pain and the acute pain(P＜0.05). The inhibition of pain is more influenced by the frequency of TENS than the time of it. Conclusion Channel and point of TENS can influence CPT of the specific reaction area. And the choice of appropriate frequency of the treatment is more important than extending the treatment time alone.
ABSTRACT
@#ObjectiveTo observe the effect of transcutaneous electric nerve stimulation (TENS) and physical therapy on shoulder pain after stroke. Methods60 patients of shoulder pain after stroke were randomly divided into treatment group (30 cases) and control group(30 cases). The patients in the treatment group were treated with TENS and physical therapy. The cases in the control group were treated with TENS only. All patients were evaluated with visual analogous score of pain (VAS) and Fugl-Meyer measure (FM) before and after treatment. ResultsThe scores of VAS and FM improved more significantly in treatment group than in control group(P<0.01).ConclusionTranscutaneous electric nerve stimulation combined with physical therapy showed more effective on shoulder pain after stroke.
