A Clinical Study of Trigger Point by Blocking Methods

유발점 차단에 의한 임상적 연구

The purpose of this study is the evaluation of the degree of post injection soreness, symptom duration, factor and autonomic symptoms after trigger point injection in patients with trigger points. We devided the subjects of the study into four groups Such as, only dry needling, needle-TENS, with massage-stretch, massage-stretch only, including 100 patients, and measured the visual analog scale before treatment and after treatment. Before treatment, The VAS mean scores were $6.2{\pm}1.03$ in needle-TENS with massage-stretch group ; $6.2{\pm}1.75$ in needdle-TENS group, and $6.3{\pm}1.85$ in dry needling group, and $6.8{\pm}1.03$ in massage-stretch group. In post injection 3rd day, The VAS mean score were $0.9{\pm}1.78$ in needling-TENS with massage-stretch group, $1.1{\pm}1.52$ in needling-TENS group, $1.7{\pm}1.10$ in dry needling group, and $3.9{\pm}3.01$ in massage-stretch group. As for a causative factor of activities for trigger were overload with 37.0%, overwork with 35.0% and fatigue with 13.0%. Symptoms for trigger were tenderness with 28.0%, numbness and tingling with 24.0%. ROM limit with 17.0% and tightness with 17.0%. As a result, needling-TENS with massage-stretch group showed less soreness and effect than other group.
