A comparison of anatomical pain sites from a tertiary care sample: Evidence of disconnect between functional and perceived disability specific to lower back pain
Bibliographic record
Abstract
Heterogeneity has been identified within chronic musculoskeletal pain (CMP) patient samples; however, investigations have typically focused on psychological constructs or coping (e.g., pain-related anxiety, catastrophizing) in this regard. Furthermore, studies to date have included either samples presenting with a specific anatomical site (e.g., only lower back pain) or a mix of anatomical sites (e.g., lower back, shoulder, or leg pain) as the primary pain complaint, without making comparisons based on the anatomical site of reported pain. For example, patients with chronic lower back pain (CLBP) may differ from those with chronic upper or lower extremity pain (ULEP) in presentation, recovery trajectory, and psychological variables. The current investigation explored whether systematic differences existed between patients participating in a multidisciplinary reconditioning third-party-payer program who have CLBP relative to patients with ULEP. Patients included those with CLBP (n=23; 35% women) or ULEP (e.g., arm, shoulder, leg, knee; n=28; 29% women). The ULEP group began and finished the program with more pain-related anxiety, more catastrophic thoughts, and more fearful cognitions than the CLBP group. There were no significant correlations between functional deficit and perceived levels of disability or associations between group and return to work status; however, there was an unexpected significant interaction between group and perceived disability. Specifically, CLBP patients reported increasing perceived disability despite improvements in functional deficit, whereas ULEP patients did not. These findings suggest a disconnect between perceived disability and function that may be specific to lower back pain. Implications and directions for future research are discussed.

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.
