Eligibility
Inclusion criteria
Inclusion criteria: 1. Healthy adults aged 20 to 40 years 2. no history of musculoskeletal, neurological, or cardiovascular disorders 3. able to safely use axillary crutches after familiarization training 4. body Mass Index (BMI) between 18.5 and 25.0 kg 5. willing to participate and provide written informed consent.
Exclusion criteria
Exclusion criteria: 1.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Physiological Cost Index (PCI) before, during and after the 15-minute walking test under each crutch condition. Physiological Cost Index calculated from heart rate and walking speed during treadmill-assisted non-weight-bearing gait using each crutch condition. | — |
Secondary
| Measure | Time frame |
|---|---|
| Muscle Activation (EMG) before, during and after the 15-minute walking test under each crutch condition. Surface electromyography (EMG) amplitude normalized to MVC (%MVC) of Triceps brachii, Latissimus dorsi, Vastus lateralis, Biceps femoris, Gastrocnemius medialis, and Tibialis anterior.,Muscle Oxygenation before, during and after the 15-minute walking test under each crutch condition. Local muscle oxygen saturation measured using near-infrared spectroscopy (NIRS Moxy Monitor) at Triceps brachii and Vastus lateralis.,Rate of Perceived Exertion (RPE) before and immediately after completion of each walking condition. Perceived exertion assessed using Borg Rating of Perceived Exertion Scale (6 to 20).,Trunk displacement before and during the 15-minute walking test under each crutch condition. A smartphone-based inertial sensor application will be attached to the trunk to measure trunk displacement and movement variability during non-weight-bearing treadmill walking. | — |
