하반신 마비 환자에서 반복적인 전기 보조 기립 운동 중 팔과 다리 기여도 정량화: 파일럿 연구

Executive Industry Relevance

Quantitative assessment of arm and leg contributions during repetitive electrically-assisted sit-to-stand (SitTS) exercises in paraplegics provides actionable insights for early-stage neuromuscular target validation and rehabilitation device development. The integration of mechanomyography (MMG) and functional electrical stimulation (FES) enables objective measurement of muscle fatigue and compensatory strategies, supporting predictive confidence in translational research. These findings inform the design and evaluation of assistive technologies and therapeutic interventions for spinal cord injury populations.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables quantitative interrogation of neuromuscular function and compensatory mechanisms in disease-relevant systems.
• Supports biological de-risking by clarifying the interplay between upper and lower limb contributions during functional tasks.
• Provides objective endpoints for functional target validation in assistive device and therapy development.

Screening & Assay Development

• Facilitates preparation of validated biomechanical and electrophysiological assays for downstream screening of interventions.
• Enables reproducible measurement of muscle activity and fatigue using MMG and force sensors.
• Supports standardization of SitTS protocols for reliable cross-study and cross-population comparisons.

Translational & Preclinical Research

• Aligns quantitative outputs with translational biomarker development for neuromuscular rehabilitation.
• Provides continuity from discovery-stage mechanistic studies to preclinical validation of assistive technologies.
• Informs risk-adjusted advancement decisions for device and therapy candidates targeting functional mobility.
