Subjective Experiences of Men With and Without Spinal Cord Injury: Tolerability of the Juvent and WAVE Whole Body Vibration Plates
Bibliographic record
Abstract
BACKGROUND: Device tolerability is an important determinant of subject adherence and intervention effectiveness. Although popular in rehabilitation settings, the tolerability of whole-body vibration (WBV) among patients with spinal cord injury (SCI) is unknown. OBJECTIVE: To assess feedback from SCI and non-SCI subjects on the usability of passive standing and WBV devices (Juvent [Juvent Medical, Somerset, NJ] and WAVE [WAVE Manufacturing, Windsor, Ontario, Canada]) using a priori specified knee postures, plate amplitudes, and frequencies. DESIGN: A matched groups design with repeated measures. SETTING: A tertiary SCI rehabilitation center. SUBJECTS: Eight men with chronic SCI (C4-L2, American Spinal Injury Association Impairment Scale A-D) and 10 men without SCI of similar height, weight, and body mass index. INTERVENTION: Subjects (N = 18; 8 with SCI) underwent intermittent WBV during passive standing (EasyStand 5000 [Altimate Medical, Morton, MN]) for 45 minutes using the optimized WAVE and Juvent plates. WBV parameters were sequentially altered every 2 minutes and included parameter combinations of (1) postures of 140°, 160°, and 180° knee extension (180° with Juvent only); (2) amplitudes of 0.7 mm and 1.1 mm (WAVE only); and (3) frequencies of 25 Hz, 35 Hz, and 45 Hz. Outcome assessments were completed at 4-minute intervals throughout WBV exposure. MAIN OUTCOME MEASURES: Qualitative, semistructured interviews were used to generate neutral, positive, and negative descriptors of the subjects' overall experience and device preference. RESULTS: SCI subjects reported a greater frequency of positive descriptors than non-SCI subjects during WBV, regardless of plate, posture, amplitude, or frequency, with the exception of 1 combination of parameters (WAVE plate at 140°, 1.1 mm, and 25 Hz). Non-SCI subjects reported the highest frequency of negative effects with the WAVE plate at 160°, 1.1 mm, 25 Hz, and 35 Hz. Non-SCI subjects preferred the Juvent, whereas SCI subjects preferred the WAVE plate. CONCLUSIONS: SCI and non-SCI subjects reported differing frequencies of positive and negative descriptors and indicated divergent device preferences. SCI subjects preferred the WAVE plate and vibration at high frequency. Future research will determine the therapeutic potential and adverse events associated with the device and WBV parameters tolerable for persons with SCI.

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.
