[Objective] To perform treatment using mechanical diagnosis and therapy (MDT) for patients withlumbar spondylolysis during the growth stage and to confirm the trend. [Subjects and Methods] After adiagnosis of lumbar spondylolysis, 33 adolescent patients (28 males, 5 females, mean age 14.3 ± 1.9 years)who consented to the treatment plan using MDT were treated. Low-intensity pulsed ultrasound therapy wasalso performed for 3 months (1/week). [Results] In MDT, directional preference (DP) was observed in allof the patients, and they were classified as derangement that can be reduced. Low back pain and lumbarrange of motion improved quickly, and they resumed sports after an average of 17.5 ± 6.7 days. [Conclusion]As a result of using MDT for adolescent patients with lumbar spondylolysis during the growth stage, allpatients were found to have DP and were classified as derangement that can be reduced, and the treatmentprogressed well. Our experience with MDT indicates new possibilities for the future treatment of low backpain during the growth stage of adolescent lumbar spondylolysis patients.
