In rehabilitation assessments electromyography procedures (commonly
known as EMGs) seem to be mainly used for diagnosis (usually to
determine if a person has nerve or muscle damage due to a workplace

A few years ago there was some research that suggested that a surface
electromyogram for back muscle endurance is also useful for assessing
the efficacy of patient rehabilitation (Koumantakis et al, 2001).

Is the use of EMGs for assessing the status of rehabilitation patient
becoming commonplace these days or do patient assessments still rely on
more traditional criteria?
