Prevalence of Musculoskeletal Disorder and Correlation with Core Endurance, Body Mass Index among Indian Classical Musical Instrument Players
Bibliographic record
Abstract
Background and need of study: Commonly all classical musical instruments are played in cross leg position and without back support for prolonged periods. Core is the central part of the body, core muscles have to spare the spine from excessive load, to transfer force from the lower body to the upper body and vice versa. Strong, stable core and normal body mass index helps us to prevent musculoskeletal injuries. Therefore; the present study was conducted to find the prevalence of musculoskeletal disorder (MSD) and correlation with core endurance and body mass index (BMI) in Indian classical musical instrument players. Methodology: Observational, analytical study was conducted on 35 Indian classical musical instrument players. Male and female, age 20-60 years old, with ≥2 years of experience as a classical musical instrument player, practicing instrument for minimum 2 hours/day were included. Participation was voluntary and informed consent was taken. Nordic questionnaire was assessed for the prevalence of MSD. Weight and height assessed by BMI. Core endurance was assessed by McGill’s core endurance test. Each subject was given appropriate rest period between all tests. Outcomes were correlated using Spearman’s correlation of coefficient. Results: The common painful sites of the body were as follows: wrist/hand(91%),low back (89%),neck(71%),upperback(49%),shoulders(49%),knees(31%),elbows(29%),ankles(20%),hips(11%) among musical instrument players. Correlation was found between BMI and trunk flexor test (r=-0.696, p≤0.001), BMI and trunk extensor test (r=-0.658, p≤0.001), BMI and right side bridge test (r=-0.649,p≤0.001,)left side bridge test (r=-0.675,p≤0.001). Conclusion: A relatively high prevalence of musculoskeletal pain amongst Indian classical musical instrument players. There is moderate negative correlation between BMI and core endurance in Indian classical musical instrument players. Ergonomic advices, adapting healthy lifestyle along with overall improvement in their working efficiency, prevent MSD and thus indirectly improve their Quality of Life.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
