Abstract: The purpose of this investigation is (1) to determine if a Feldenkrais awareness through movement technique creates a measurable physiological change in muscular activity, (2) to determine if there is a perceptual recognition of a physiological change, and (3) to determine if perceptual recognition may be induced as a result of suggestion, imagery, and visualization. Twenty-one subjects were divided into two groups. Electromyographic (EMG) activity was recorded during a flexion movement with surface electrodes placed over the left lumbar paraspinal muscles at L3-L5 and over the right external oblique muscle. Ratings of perceived exertion (RPE) were taken after the EMG testing. Correlated t tests were performed to test significant differences within each group, and small sample means tests were performed to test for significant differences between the two groups. The results show that there was a significant difference in EMG activity of the flexors and of RPE values within each group; however, there were no significant differences between the two groups. The results support the following conclusions: (1) the Feldenkrais method produces a change in the amount of muscular activity as measured by EMG required to perform a movement task; (2) a perceptual recognition of the change in muscular activity is produced; and (3) this perceptual recognition of change is not the direct result of the use of suggestion, imagery, and visualization. This study supports the use of the Feldenkrais Method clinically for increasing attention to posturing, movements, and changes in muscular activity with movements.
