The Effect of a Pelvic Clock Tool Exercise on Central Muscle Endurance, Trunk Range of Motion, and Pain Intensity in Middle-aged Women With Nonspecific Chronic Low Back Pain
Bibliographic record
Abstract
Background and Aims Despite the advancement of medicine in managing spinal diseases and the increasing development of treatment methods, back pain has remained one of the significant public health problems in industrial and non-industrial countries. Therefore, the present study aimed to investigate the effect of a course of exercise with a pelvic clock device on the endurance of central body muscles, torso range of motion, and pain intensity in middle-aged women with nonspecific chronic low back pain. Methods The present study was quasi-experimental with a pre-test-post-test design and a control group. The statistical population of the present study consisted of middle-aged women with nonspecific chronic low back pain in the age range of 35-50. The statistical sample of the study included 30 middle-aged women who were purposefully and accessibly selected from the study›s statistical population based on the inclusion and exclusion criteria. The exercise protocol was performed with a pelvic clock device for 8 weeks (3 sessions of 45 minutes per week) by a researcher in a sports club. Central body muscle endurance indices were measured using the McGill test (trunk flexural endurance test for abdominal muscle endurance) and modified Bearing Sorenson test. Also, the trunk range of motion and pain intensity were assessed using Schubert's modified test and visual analog scale. The measurement was made while the control group participated only in the pre-test and post-test stages. The paired t-test and independent t-test were used for intra-group and inter-group comparisons, respectively, at a significance level of 0.05. Results The results showed that 8 weeks of exercises with a pelvic clock device could affect the endurance of the muscles of the central body, the range of motion of the trunk, and the severity of pain in middle-aged women with nonspecific chronic low back pain. However, it did not affect the control group (P≤0.05). Conclusion According to the present study findings, it is suggested that exercises with pelvic clock device are used as a cheap and practical modality to increase endurance of central body muscles and torso range of motion but reduce pain in middle-aged women with nonspecific chronic low back pain. It could also be used as a method of prevention.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
