Core strength assessment evaluates the strength and quality of activation of the transversus abdominis muscle, which as mentioned in several articles on this site plays a key role in stabilizing the lower back to not only reduce lower back pain, but also to increase performance in everyday functional activities and in all sports.  In addition, the strength and flexibility of other “core” muscles such as the lower abdominals, oblique abdominals, gluteus medius, gluteus maximus and iliopsoas (hip flexor) muscles will be evaluated.  Core strength serves as a baseline for the design and implementation of a complete Core strength training program.
