Examinations of 113 elite male high school tennis players (35 of whom had low back pain) revealed an association between restricted internal hip rotation range of motion and low back pain.

Doctors of chiropractic are trained to evaluate the whole patient and not just focus on the area of chief complaint as issues elsewhere in the body may need to be addressed to achieve a satisfactory outcome.
