A System for Unveiling the True Dynamics of Musculature: The Small Animal Muscle
埃飞电子 2025-12-05
In skeletal muscle research, mechanical behavior in animal models has long posed challenges for investigators.
Traditional force measurement techniques often focus solely on unidimensional tension data, failing to capture the true functional performance of muscles in physiological environments. There is a growing need for integrated tools capable of analyzing muscle biomechanics across multiple dimensions and experimental settings.
The Tri-Mode Muscle Testing System is designed to address this gap.
From Single-Point Measurement to Comprehensive Biomechanical Profiling
This system uniquely integrates **in vivo, in situ, and in vitro** testing modalities on a unified platform, allowing flexible experimental design. Whether preserving neural and circulatory inputs in vivo, maintaining tendon attachments under controlled conditions in situ, or conducting precise isolated muscle preparations, the system ensures stable, quantifiable, and highly reproducible operations.
Dual-Mode Sensors: Simultaneous Force and Length Recording
At its core, a dual-mode sensing mechanism synchronously controls and acquires two critical parameters: **force and length**. This enables studies beyond isometric contractions, including:
- Isotonic contractions
- Concentric/eccentric contraction analysis
- Force–length and force–velocity relationships
- Stiffness dynamics
- Work-loop and fatigue characterization
These previously challenging biomechanical assessments can now be standardized and automated.
User-Centric Experimental Design
The system combines high performance with practical usability:
- Temperature-controlled platform for physiological conditions
- Adaptable fixtures for murine models of various sizes
- Modular architecture for rapid configuration changes
- Programmable software for automated stimulation, length adjustment, and data acquisition
The intuitive software interface allows predefined or custom experimental protocols, transforming complex biomechanical testing into streamlined workflows.
Expanding Research Applications
The system supports diverse investigative areas, such as:
- Muscle atrophy and aging
- Exercise biology
- Diabetes-induced myopathy
- Neuromuscular disorders
- Skeletal muscle injury and regeneration
- Drug intervention efficacy
- Phenotypic analysis of genetically modified models
It serves as a robust tool for studies in metabolism, neuroscience, sports science, rehabilitation, and biomechanics.
