Background: The investigation aimed to assess the impacts of magnesium sulphate (MgSO4) iontophoresis and high-power pain-threshold ultrasound (HPPT-US) on pain, range of motion (ROM), and functional activity in physical therapy students suffering from mechanical cervical pain.

Methods: Typically, 75 males aged 19 to 30 years suffering from mechanical neck pain were enrolled in this investigation. Participants were divided at random into three groups. Group A received iontophoresis plus conventional physical therapy program, Group B received HPPTUS along with conventional therapy, and Group C received conventional therapy only. The outcomes were pain evaluated by visual analog scale (VAS) and Digital Electronic Pressure Algometer, cervical range of motion measured by Myrin gravity reference goniometer, and Arabic Neck disability index (ANDI) evaluate neck function.

Results: The differences within and between groups were detected utilizing a mixed-design multivariate analysis of variance (MANOVA). The within- and between-group analysis of all outcome measures revealed that there were statistically significant differences at post-intervention between high-power ultrasound and conventional group at all variables and also between iontophoresis and conventional group, but there was no statistically significant variation between high-power ultrasound and iontophoresis.

Conclusion: MgSO4 iontophoresis and HPPT-US are effective in decreasing pain, improving neck function, and improving neck ROM in subjects with mechanical neck pain who have active myofascial trigger points (MTrPs) on the upper fibers of the trapezius with no superiority of one over the other.

Trail Registration: The study was registered in the Clinical Trials Registry (registration no: NCT05474898) 26/7/2022.
