Abstract
A rear mounted, powered, drive wheel has been developed to assist with mobility for manual wheelchairs. The version tested operates in two modes (indoor and outdoor). To start in the indoor mode users must initiate propulsion with sufficient force to trigger the motor. To stop users must apply a braking force through the handrims. . The objectives of this study were to compare (1) the minimum force required to start a wheelchair with and without the drive, and (2) the distances and forces needed to stop a wheelchair at different treadmill speeds with and without the device. We used a crossover study design with 24 able-bodied persons. The main outcome measures were starting force single push speed, stopping distance, and stopping force. Participants did not have significantly increased starting force or single push speed using the drive. Participants had significantly shorter absolute stopping distance (p = 0.045 and reduced stopping force (p = 0.02) using the add-on at both treadmill speeds. Given the decreased stopping distances, the add-on may be a viable option for wheelchair users with limited upper limb strength.

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 it
