Kinesiologist-delivered mobilization to mitigate inpatient frailty: A study protocol for a randomized controlled trial
Bibliographic record
Abstract
BACKGROUND: Hospitalized older adults spend excessive amounts of time in sedentary postures (sitting/lying while awake). Mobilizing patients may prevent physical deconditioning, exacerbated frailty levels, and worsened hospital outcomes. The purpose of this study will be to test the hypothesis that compared to usual care, patients who receive multiple kinesiologist visits each day will, 1) increase their step counts and upright time, 2) decrease their frailty levels from admission to discharge, and 3) have shorter lengths of stays and decreased readmission rates. METHODS: Sixty middle-aged-to-older adult patients (≥50 years) from a general/internal medicine unit will be randomized into a usual care control (visit from the kinesiologist once/day) or intervention group (multiple visits from the kinesiologist/day). Kinesiologist visits will include individualized patient mobilization. All participants will be equipped with three waterproofed activPAL inclinometers positioned on their thigh, torso, and shin for 24-h/day throughout hospitalization to measure physical activity (step counts, physical activity intensity), upright postures, and detailed sedentary postures (bent-legged sitting, straight-legged sitting, lying). Frailty will be assessed via a validated 65-item index and the Clinical Frailty Scale two weeks before admission (retrospectively), at admission, and at discharge. Secondary measures will include length of stay and hospital re-admissions. Mixed models for repeated measures will determine whether daily activity differed between groups, changed throughout hospital stay, and effected frailty levels. DISCUSSION: This randomized controlled trial will aim to refine mobilization strategies and individualize interventions for the prevention of decline in mobility and worsening frailty among hospitalized patients. TRIAL REGISTRATION: The protocol has been registered at clinicaltrials.gov (identifier: NCT06802289).

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.
