A randomized controlled clinical trial with two groups (intervention and placebo) will be implemented. The intervention group will have the Mezieres technique as postural treatment while the placebo group will follow a total of 6 isostretching positions.~In total, the two treatments with 30 minutes and duration or with a frequency of 2 weekly sessions will be implemented for a period of 12 weeks. All treatments will be performed by the same certified therapist and with a minimum of 5 years of experience in postural treatments. The measurements will be made immediately after the first session, in 2 weeks, 6 weeks and in the last week of intervention by a blind researcher who did not participate in the treatments, but with experience in this field.
Introduction: Low back pain is a musculoskeletal disorder that is associated with symptoms such as pain, limitation of joint range and postural problems in athletes. Methods: The study design is a randomized controlled clinical trial with a minimum of 35 elite gymnasts with back pain. Two postural treatments will be implemented, Mezieres Method and Isostretching to verify if there is improvement of back pain in gymnasts and to compare both procedures. Discussion: This trial could generate a greater understanding of the importance of posture related to low back pain and its possible treatments.
