About this trial

This pilot study investigates the feasibility of objectively quantifying movement amplitude and amplitude decay during large-amplitude exercises using RGB camera-based video analysis in healthy volunteers. Six large-amplitude exercises are recorded across repeated trials, with the first repetition clinically confirmed as the individual's maximum reference. Movement amplitude is quantified using pose-based kinematic measures and complemented by an exploratory self-supervised visual transformer approach to characterize repetition-wise changes relative to the reference execution. The study aims to determine whether camera-based methods can detect amplitude decay patterns and identify moments requiring clinical verbal cues, thereby supporting future objective monitoring and feedback in large-amplitude exercise training.

Eligibility criteria

This trial accepts healthy volunteers

History of neurological disorders (e.g., Parkinson's disease, stroke, multiple sclerosis, traumatic brain injury).

Trial design

Design model

Single group

Treatments tested in this trial

  • Large-Amplitude Exercise Observation and Video Recording

    Other intervention

    Participants perform six standardized large-amplitude exercises (Floor-to-Ceiling Reach, Forward Step, Side Step, Sit-to-Stand, Forward Reach to Grasp and Release an Object, and Big Walking). Each exercise is repeated eight times while full-body movement is recorded using an RGB camera. The first repetition of each exercise is clinically confirmed as the participant's maximum movement amplitude and used as a reference for subsequent observational analysis. No therapeutic manipulation or feedback is provided beyond standard verbal confirmation.

Trial outcomes

Primary outcomes

1

Change in Movement Amplitude Across Repetitions

Movement amplitude will be quantified for each repetition of six large-amplitude exercises using normalized, RGB camera-based pose estimation. Amplitude decay will be defined as the change in movement amplitude across repeated executions within each exercise, reflecting repetition-related reduction in movement scali

Time frame
Baseline

Secondary outcomes

1

Reference-Based Visual Similarity Score

A repetition-wise visual similarity score will be computed by comparing each repetition to the clinician-confirmed maximum reference repetition using data-driven video feature representations. Lower similarity indicates greater deviation from the maximum-amplitude execution.

Time frame
Baseline
2

Repetition-Wise Amplitude Decay Trend

Within-exercise repetition trends will be quantified using early-late repetition comparisons and slope-based measures to characterize the progression of amplitude decay across repetitions.

3

Association Between Kinematic Amplitude and Visual Representation Measures

Correlation between pose-based movement amplitude metrics and reference-based visual similarity scores will be evaluated to examine agreement between kinematic and visual measures of movement scaling.
