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.
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.
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.
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.
The study was registered in the Clinical Trials Registry (registration no: NCT05474898) 26/7/2022.
本研究旨在评估镁离子透入疗法（MgSO4 离子电渗疗法）和高功率疼痛阈值超声（HPPT-US）对患有机械性颈痛的物理治疗学生的疼痛、活动范围（ROM）和功能活动的影响。
本研究共纳入 75 名年龄在 19 至 30 岁之间的男性机械性颈痛患者。参与者被随机分为三组。组 A 接受离子电渗疗法加常规物理治疗方案，组 B 接受 HPPT-US 联合常规治疗，组 C 仅接受常规治疗。使用视觉模拟评分（VAS）和数字电子压力测痛计评估疼痛，使用 Myrin 重力参考量角器测量颈椎活动范围，使用阿拉伯颈痛残疾指数（ANDI）评估颈部功能。
采用混合设计多元方差分析（MANOVA）检测组内和组间差异。对所有结局指标的组内和组间分析显示，干预后高功率超声组与常规组在所有变量上均存在统计学差异，离子电渗组与常规组之间也存在统计学差异，但高功率超声组与离子电渗组之间无统计学差异。
MgSO4 离子电渗疗法和 HPPT-US 可有效减轻患有机械性颈痛且斜方肌上纤维有活动性肌筋膜触发点（MTrPs）的受试者的疼痛，改善颈部功能和 ROM，两者在疗效上无优劣之分。
该研究于 2022 年 7 月 26 日在临床试验注册中心（注册号：NCT05474898）注册。
