“…1,6 It can be assumed that, in cases of postural instability, the insufficient stabilizers must be compensated by other muscles. A significant decrease in strength of trunk muscles, especially the extensors, in patients with low back pain has been established, 8,23,34,37,38 suggesting that strengthening exercises of the trunk muscles may be an optimal rehabilitation strategy.…”

FIGURE 2. (A) Subtracted image of the diaphragm excursions in the most caudal (inspiratory) and cranial (expiratory) diaphragm positions during tidal breathing in a healthy control. (B) A subtracted image of the diaphragm excursions in the most caudal (inspiratory) and cranial (expiratory) diaphragm positions during tidal breathing in a patient with chronic low back pain. (C) Schematic description of 3 diaphragmatic points (B, C, and D) used for diaphragm excursion calculations. The following 6 distances (in mm) were obtained by measuring the distance between the horizontal baseline in both expiratory and inspiratory diaphragm positions. Diaphragm excursion points: B1 to D1 were derived from the inspiratory diaphragm positions obtained from MRI images; B2 to D2 were derived from expiratory diaphragm positions obtained from respective MRI images. The inspiratory diaphragm position is designated by points B1, C1, and D1. The expiratory diaphragm position is designated by points B2, C2, and D2. Total diaphragm excursion is designated by the distance from the lower to the upper curve along points B1 to B2, C1 to C2, and D1 to D2. Adapted from Kolar et al.

“…In wrestlers, the prevalence of nsLBP in athletes with and without LRA has been reported to be 40% and 44%, demonstrating no specific association between nsLBP and LRA. 12 Authors of previous studies reported that individuals without nsLBP had high prevalence of LRA (general population, 32% 26 ; wrestlers, 70% 12 ). To date, there has been no report that has examined the possible association between nsLBP and LRA in judo athletes.…”

STUDY DESIGN: Cross-sectional study of a specific population. OBJECTIVES:To investigate the prevalence and coprevalence of nonspecific low back pain (nsLBP) and lumbar radiological abnormalities (LRA) in judo athletes.BACKGROUND: nsLBP and LRA occur frequently in judo athletes. High body mass has been reported to be associated with both nsLBP and LRA. METHODS AND MEASURES:The subjects comprised 82 male judo athletes (mean SD age, 20.1 0.9 years) from 3 weight categories: lightweight (n = 29), middleweight (n = 31), and heavyweight (n = 22). The presence of nsLBP was evaluated using a questionnaire. LRA were examined using plain-film radiographs and magnetic resonance imaging. The prevalence of nsLBP and LRA were compared among weight categories. RESULTS:The prevalence of nsLBP in the lightweight, middleweight, and heavyweight categories was 34.5%, 32.3%, and 40.9%, respectively. For LRA, prevalence for the 3 weight categories was 65.5%, 90.3%, and 90.9%, respectively (middleweight and heavyweight greater prevalence than lightweight [P .05]). The prevalence of LRA in athletes with nsLBP in each category was 50.0%, 100%, and 88.9%, respectively (middleweight greater prevalence than lightweight [P .05]). The prevalence of LRA in athletes without nsLBP in each category was 73.7%, 85.7%, and 92.3%, respectively. CONCLUSIONS:The prevalence of LRA was approximately 90% in the middleweight and heavyweight categories, which was greater than for the lightweight category. There was a large coprevalence of nsLBP and LRA. However, many judo athletes without nsLBP had LRA. The presence of LRA may not have a direct association with nsLBP.

Trunk Muscle Strength and Disability Level of Low Back Pain in Collegiate Wrestlers
