The MyoDynamics Muscle Strip System - 840MD represents a state-of-the-art 4-channel muscle strip system for intact muscle or muscle strips of up to 30 mm in length. The easy-to-use system allows the muscle physiologist to perform isometric, eccentric, and concentric contractions protocols performed by the build-in motors in a precise manner under a range of conditions, including electric field stimulation.
The system allows for four separate baths to run simultaneously and independently from each other. The system gives the flexibility to program each bath individually and initiate ad stop protocols independently from the other baths. Each muscle bath unit, made of aluminum, features a stainless steel chamber. The tissue mounting supports are positioned in the chamber, with one side attached to the force transducer and the other to a combination manual positioner screw and a motorized micropositioner. The manual positioner allows the accurate preload/base tension setting, while the motorized micropositioner permits the user to stretch (Eccentric)/relax (Concentric) the muscle according to user-defined settings. The sensitive force transducers provide measurements of contractile forces. Mounted tissue can be stretched and relaxed, defined by the user with a minimum distance of 10µm up to 11mm and a maximum speed of 11mm/sec. The 840MD comes with a controller software that enables autonomous experimentation. The software includes 30+ commands that allows parameters to be set for motor speed, pull range, force change and more. This also enables eccentric experimentation where the motors can start at the moment of muscle strip contraction. Stimulation electrodes built into the chamber cover (optional - various types) can activate the muscle via field stimulation from the DMT Stimulator. The 840MD has input and output trigger functions to activate the build-in motors by the DMT stimulator or visa versa. This system is well suited for studies involving muscle reactivity and fatigue experiment connected to neuromuscular disorders such as muscular dystrophy, metabolic, ataxia, and myofibrillar myopathies. Multiple units can be arranged side-by-side to facilitate high-throughput screening, such as drug testing or experiments requiring the separation of muscle preparations in individual baths. |
