Abstract

ABSTRACT Objective: To evaluate the efficacy of acute chiropractic adjustment in individuals who practice CrossFit with regard to complaints of low back pain and the joint range of motion in this region. Methods: A randomized clinical trial comprised of CrossFit practitioners from a box in Novo Hamburgo-RS, of both sexes and aged 18 to 40 years who had low back pain at the time of the study. The following tools were used: Semi-structured Anamnesis Questionnaire, Visual Analog Scale, McGill Pain Questionnaire, and SF-36 Quality of Life Questionnaire. Individuals in the control group answered the questionnaires before and after CrossFit training. The chiropractic group performed the same procedure, plus pre-training chiropractic adjustment and joint range of motion (ROM) before and after lumbar adjustment. Results: There was a significant increase in pain in the control group, and a significant decrease in pain in the chiropractic group, including one day after the chiropractic adjustment. In the chiropractic group, the joint ranges of motion had a significant increase in flexion and extension of the lumbar spine after chiropractic adjustment. Conclusion: The chiropractic group achieved a significant improvement in pain level and joint range of motion, suggesting that acute chiropractic adjustment was effective in reducing low back pain.

Highlights

  • Physical activity is advocated as an important tool in preventing the emergence of diseases, controlling already existing diseases, and for the well-being and social life of human beings.[1,2] Sports and physical activity do not seem to be the main cause of spine pain and injuries, but the frequent additional load on the biological structures of the spine during high-impact sports may be a prerequisite for injury

  • The objective of this study is to evaluate the effectiveness of acute chiropractic adjustment in individuals who practice CrossFit training, in relation to complaints of pain and range of joint movement in the lumbar region

  • Individuals involved in any type of physical rehabilitation, drug treatment for pain, with any contraindication to chiropractic adjustment, who had a history of lumbar spine surgery, and those who did not answer the questionnaire within 24 hours of the chiropractic adjustment were excluded

Summary

Introduction

Physical activity is advocated as an important tool in preventing the emergence of diseases, controlling already existing diseases, and for the well-being and social life of human beings.[1,2] Sports and physical activity do not seem to be the main cause of spine pain and injuries, but the frequent additional load on the biological structures of the spine during high-impact sports may be a prerequisite for injury. In CrossFit training, individuals perform repetitive movements of lifting weights, squatting, and improper posture,[9,10] and an evaluation of whether these movements are being performed incorrectly during training, whether from carelessness or lack of guidance, is extremely important. These activities, when repeated frequently, can lead to spine problems and intense pain, especially in the lumbar region, where most of the weight is normally supported.[11,12] The adoption of poor posture provokes muscular imbalance and limits joint amplitude, hindering normal ranges of joint movement and possibly triggering painful processes.[13,14,15]
