“…A meta-analysis of 6 RCTs identified the potential effect of rPMS to alleviate pain and enhance functional ability in patients with CLBP [ 21 ]. This is consistent with our discovery that combining rPMS and CMT produces a greater analgesic effect than the sham-rPMS with CMT, while dysfunction is reduced in both interventions.…”

“…The analgesic efficacy in treating neuropathic pains such as migraine has been supported [ 14 – 16 ]. Several studies have primarily identified a positive role for rPMS in acute [ 17 , 18 ] and chronic low back pain [ 19 , 20 ], indicating that the potential effect is to elicit convulsive contractions of paravertebral muscles, leading to pain relief, enhanced muscle strength, increased proprioceptive input, reduced swelling, and improved blood circulation [ 13 , 21 ]. However, given variations in stimulation intensities, sites, and frequencies, it is imperative to include higher quality evidence to substantiate its clinical efficacy [ 21 ].…”

Introduction Patients with chronic non-specific low back pain (CNLBP) often experience impaired postural control, contributing to pain recurrence. Although repetitive peripheral magnetic stimulation (rPMS) combined with core muscle training (CMT) could improve postural control, its neural mechanism remains unclear. This study aims to investigate the postural control-related cortical mechanism of the effect of rPMS on patients with CNLBP. Methods This unicentric, prospective, randomized, double-blind, controlled trial was conducted in a public hospital from May to December 2023. A total of 40 patients (27 females and 13 males, mean age 29.38 ± 7.72) with CNLBP were randomly assigned to either the rPMS group (real rPMS with CMT) or the sham-rPMS group (sham-rPMS with CMT) for 12 sessions over 4 weeks. The rPMS was applied to the lumbar paravertebral multifidus muscle on the painful side. Pain and disability were quantified using the visual analog scale (VAS) and Oswestry dysfunction index (ODI) pre- and post-intervention. Furthermore, the sway area and velocity of the center of pressure (COP) were measured using a force platform. The cortical activities in 6 regions of interest during 4 tasks (standing with eyes open/closed on a stable/unstable plane) were recorded by functional near-infrared spectroscopy (fNIRS) pre- and post-intervention. The repeated measure ANOVA was applied for statistical analysis. Spearman's correlation was used to determine the relationships between variables. Results After the intervention, the rPMS group showed decreased pain intensity ( p = 0.001) and sway area (unstable eyes-closed task) ( p = 0.046) compared to the sham-rPMS group. Additionally, the rPMS group exhibited increased activation in left primary motor cortex (M1) ( p = 0.042) and reduced in left supplementary motor area (SMA) ( p = 0.045), whereas the sham-rPMS group showed no significant changes. The increased activation of left M1 was negatively correlated to the reduction of pain intensity ( r = − 0.537, p = 0.018) and sway area ( r = − 0.500, p = 0.029) under the static balancing task. Furthermore, there was a positive correlation between sway velocity and VAS ( r = 0.451, p = 0.046) post-rPMS intervention. Conclusion Repetitive peripheral magnetic stimulation combined with core muscle training demonstrated better analgesic effects and postural control improvements, compared to sham-stimulation. This may be attributed to the increased activation of the left primary motor cortex. Clinical Trial Registration The trial was registered on ClinicalTrials.gov (ChiCTR2300070943).

The intricate nature of pain classification and mechanism constantly affects the recovery of diseases and the well‐being of patients. Key medical challenges persist in devising effective pain management strategies. Therefore, a comprehensive review of relevant methods and research advancements in pain management is conducted. This overview covers the main categorization of pain and its developmental mechanism, followed by a review of pertinent research and techniques for managing pain. These techniques include commonly prescribed medications, invasive procedures, and noninvasive physical therapy methods used in rehabilitation medicine. Additionally, for the first time, a systematic summary of the utilization of responsive biomaterials in pain management is provided, encompassing their response to physical stimuli such as ultrasound, magnetic fields, electric fields, light, and temperature, as well as changes in the physiological environment like reactive oxygen species (ROS) and pH. Even though the application of responsive biomaterials in pain management remains limited and at a fundamental level, recent years have seen the examination and debate of relevant research findings. These profound discussions aim to provide trends and directions for future research in pain management.
