2015 ParaPan American Games: Autonomic Function, But Not Physical Activity, Is Associated with Vascular-Cognitive Impairment in Spinal Cord Injury
Bibliographic record
Abstract
Autonomic dysfunction and diminished capacity for physical exercise are commonly implicated in the 3- to 4-fold increased risk of cerebrovascular disease after spinal cord injury (SCI). We assessed cerebrovascular function (transcranial Doppler; neurovascular coupling [NVC], and cerebral pressure-flow regulation) in elite national level wheelchair rugby players (n = 23), normally active SCI individuals (n = 12), and able-bodied controls (n = 13). Cognitive (Stroop test) and autonomic function (postural change) also were evaluated. SCI individuals demonstrated reduced posterior cerebral blood flow, as well as impaired cerebrovascular and cognitive function. Autonomic dysfunction but not physical activity was related to impaired NVC and cerebral pressure-flow regulation after SCI. Routine upper-body exercise, as utilized by elite wheelchair rugby athletes, may not elicit beneficial cerebrovascular effects. On the other hand, autonomic dysfunction needs to be considered a key culprit in cerebrovascular diseases after SCI.

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.
