Psychophysiological Biomarkers to Assess the Effectiveness of Surface EMG Biofeedback as an Alternative Therapy to Reduce Chronic Low Back Pain

Chronic low back pain (CLBP) is a multifaceted condition with a range of adversative sequelae including mental and physical disability, social issues, and increased healthcare utilization. CLBP is one of the leading worldwide health problems however it has a benign nature. It is now accountable for more years lived with disability (YLDs) than any other chronic health problem. Chronic low back pain caused 72 million YLDs in 2013 approximately which is 1.5 times greater than that of depression and twice as high as that of diabetes. Further, in 2013, around 615 million individuals globally were affected by disabling chronic low back pain. Additionally, chronic low back pain and its accompanying disability also have a major economic burden on the country. According to an estimation, between 5 to 10% of low back pain cases will develop chronic low back pain (CLBP), which is ultimately accountable for the increased cost of treatment, a high number of sick leaves, and individual suffering and also one of the leading cause for individuals seeking health care services. Disparagingly, the issue of CLBP is not well understood in developing countries like Pakistan, Sri Lanka, India, and Bangladesh, which are in the process of development and experiencing economic development and a double burden of diseases. The chronic low back pain prevalence in Southeast Asian countries is reported to be very high, for instance much higher than that reported in the Western world. The prevalence of CLBP in Bangladesh is 64% followed by Pakistan which has a 40% prevalence rate and Sri Lanka and India 36% and 19%, respectively. Previous research studies have focused on the documentation of factors that are termed "yellow flags" which induce, aggravate, and enhance pain and disability in chronic low back pain patients. Psychological and social factors are considered important contributing factors in the bio-psychosocial approach for chronic low back pain management and its relationship with disability. Moreover, this study is in line with the United Nations' Sustainable Developmental Goals (UN-SDG) 2030 plan; Goal 3.d i.e. to "strengthen the capacity of all countries, in particular developing countries, for early warning, risk reduction and management of national and global health risks". Thus, this study protocol will be a randomized controlled trial that is specifically designed to compare the biofeedback surface EMG effectiveness for chronic low back pain in the Pakistani population.
