Electromyography-biofeedback for chronic low back pain: A qualitative cohort study

Area of Science:

• Rehabilitation Medicine
• Pain Management
• Digital Health

Background:

• Chronic low back pain (CLBP) significantly impacts physical functioning, sleep, and mental health.
• Surface electromyography-biofeedback (sEMG-BF) is a potential non-pharmacological intervention for CLBP.
• Virtual delivery of sEMG-BF may improve accessibility and adherence to treatment.

Purpose of the Study:

• To qualitatively explore the impact of a virtual sEMG-BF intervention on adults with CLBP.
• To understand participants' experiences, perceived benefits, and challenges associated with the intervention.
• To identify implementation factors and barriers for future sEMG-BF programs.

Main Methods:

• Qualitative study involving 26 adults with CLBP who completed an 8-week virtual sEMG-BF program.
• Semi-structured telephone interviews were conducted by trained interviewers.
• Thematic analysis of interview data was performed using MAXQDA 2022 software.

Main Results:

• Participants reported perceived reductions in CLBP symptoms, including pain and stress.
• Positive effects on self-awareness and sleep quality were noted.
• Key themes included virtual experience, device accessibility, perceived benefits, implementation, and desire for flexibility, with no adverse events.

Conclusions:

• Virtual sEMG-BF intervention led to both physical and psychological improvements in participants with CLBP.
• The study identified specific implementation procedures and critical barriers to the intervention.
• The importance of accessible CLBP care, especially during the COVID-19 pandemic, was highlighted.
