Abstract
The aim of this study was to compare the effects of lidocaine phonophoresis to progressive pressure release on upper trapezius myofascial trigger points. Thirty six patients (20 females and 16 males) with active trigger points. Their age ranged from 20 to 30 years with a mean age (24.88 ± 3.50). Patients were randomly divided into three equal groups A, B and C. group A received lidocaine phonophoresis for 5 minutes duration for four sessions. group B received progressive pressure release technique for 2 minutes for four sessions. group C (control group) didn{u2019}t receive any treatment. Pressure pain threshold (PPT), Neck disability index (NDI) and visual analogue scale (VAS) were used to evaluate patients at three intervals (pre treatment, post treatment and at two weeks follow up). Within group analysis there was significant difference of PPT, NDI and VAS at three group while (p < .05). At post treatment, the between group analysis revealed a significance difference between group in the favor of group A for PPT (A 117%, B 83% and C 33%), NDI (A 79%, B 54% and C 29%) and VAS (A 88.3, B 79% and C 33%). At follow up, there was a significance difference between group in the favor of group A for PPT (A 149%, B113% and C 52%), NDI (A 86%, B 47% and C 47%) and VAS (A 90%, B 74% and C 55%). Lidocaine phonophoresis is more effective than progressive pressure release in treatment of active trigger points at patients with myofascial pain syndrome
