加速度計を使用して日常生活に上肢のパフォーマンスを定量化する方法

Executive Industry Relevance

Quantifying upper limb performance in real-world settings addresses a critical gap in neurorehabilitation and translational research by providing objective, continuous data beyond clinic-based assessments. This accelerometry-based methodology enhances predictive confidence in intervention outcomes and supports risk-adjusted advancement decisions for therapeutic candidates targeting motor recovery. Its reproducibility and scalability position it as a valuable asset for portfolio-level evaluation of functional endpoints in neurological disorders.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables objective measurement of functional recovery, supporting target validation for neurorehabilitation interventions.
• Facilitates mechanistic de-risking by quantifying real-world limb use rather than relying on subjective reports.
• Provides reproducible endpoints for evaluating biological impact of candidate therapies.

Screening & Assay Development

• Delivers standardized, quantitative outputs (hours of use, use ratio, magnitude ratio, bilateral magnitude) for downstream analysis.
• Supports assay reproducibility and cross-study comparability through consistent data collection protocols.
• Prepares validated datasets for screening intervention efficacy in diverse patient populations.

Translational & Preclinical Research

• Aligns functional measurement with disease-relevant endpoints for translational biomarker development.
• Enables continuity from discovery through preclinical and early clinical validation by tracking real-world outcomes.
• Supports risk-adjusted go/no-go decisions based on objective, ecologically valid performance data.
