Three cases of isolated strains of the tensor fasciae latae muscle are reviewed. Objective and subjective findings, including the differentiation between iliotibial band and tensor fasciae latae are discussed. Conservative measures of treatment and the technique of stretching the tensor fasciae latae are described. The importance of examining this muscle in the evaluation of the contractile elements of the hip is stressed.J Orthop Sports Phys Ther 1985;5(4):201-203.
