Non-invasive brain stimulation for chronic low back pain: current techniques and future perspectives

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Pain Management

Background:

• Chronic low back pain (CLBP) is prevalent, impacting physical, mental, and cognitive health.
• CLBP involves maladaptive brain changes in areas like the sensorimotor cortex and prefrontal cortex.
• Traditional treatments may not fully address the central nervous system's role in CLBP.

Purpose of the Study:

• To review targets and mechanisms of non-invasive brain stimulation (NIBS) for CLBP.
• To summarize current clinical applications of transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) in CLBP.
• To explore future prospects of NIBS in CLBP management.

Main Methods:

• Literature review of studies on NIBS for CLBP.
• Analysis of mechanisms involving sensorimotor cortex, prefrontal cortex, and cerebellar modulation.
• Summary of clinical evidence for TMS and tDCS in CLBP patients.

Main Results:

• NIBS techniques demonstrate therapeutic potential for CLBP.
• TMS and tDCS are key NIBS modalities showing clinical application.
• Brain structural and functional alterations in CLBP patients are potential targets for NIBS.

Conclusions:

• NIBS offers novel rehabilitation strategies for chronic low back pain.
• Further research into NIBS mechanisms and applications is warranted.
• NIBS holds promise for improving outcomes in CLBP management.
