The effect of muscles energy technique in the management of chronic mechanical low back pain: A scoping review.

Background: The Muscle Energy Technique (MET) is one of the treatments of choice for the management of chronic mechanical low back pain (MLBP); however, there is a paucity of evidence to justify its effectiveness.
Objectives: The objectives of this review are to explore, analyze and summarize the available evidence related to the effectiveness of MET in the management of chronic MLBP.
Method: The scoping review methodology was adopted based on a recommendation from the work of Arksey and O'Malley, to systematically appraise literature and map the existing evidence on the effectiveness of MET in the management of chronic MLBP. A systematic search was performed comprising of an electronic search of online databases using key search terms and subsided by a hand search to identify the existing literature on the topic which was summarized and discussed.
Result: Initially 25,195 hits were identified which were screened to examine their eligibility based on predetermined inclusion criteria after removing duplicate articles. Eleven articles met the inclusion criteria and were discussed.
Conclusions: Generally there exists a scarcity of published articles on the effect of MET in chronic MLBP. However, the analysis of the retrieved articles showed that the MET procedure is a favourable intervention that is safe (i.e. no adverse effects) and can be effective as a standalone treatment or in combination with other treatment strategies for patients with chronic MLBP with the potential to provide numerous physical and psychosocial benefits.
