Grip-Strength Meter (GSM) for Mice and Rats

Product Code:47200

The Grip Strength Meter automatically measures grip strength of forelimb, hind limb, or all four limbs, in rats and mice as they instinctively resist backwards movement. For assessing the effects of substances (drugs, toxins, muscle relaxants) and conditions (disease, ageing, neural damage) on muscle strength. Integrated sensor and amplifier for precision measurements and consistency. Stand-alone (battery powered) or connect to PC software supplied. Includes stainless-steel T-shaped bar, 2 stainless-steel trapeze bars, a plastic grasping grid, a plastic grasping grid partly blind and a stainless-steel orientable grid (40,3g). Easy-to-use control unit with display, internal memory and quick data transfer (.csv).

Background 

  • To stop an involuntary backward movement, the animal instinctively grabs the grasping bar when pulled backwards by the tail.
  • Neuromuscular function studies in rodents are achievable with the GSM determining the grip peak-pull force

Automated detection, standalone or PC-based

  • Automatically stores and displays the peak pull-force (peak tension) achieved by the limbs before the animal loses grip.
  • The grip strength meter has a reliable and automated detection of the animal response thanks to its peak detector.
  • The slope feature is useful to verify if the desired force has been applied with consistency.
  • The quality control software tool shows the applied pulling force, the desired target force rate and the peak detection in real time.
  • A force sensor and a peak amplifier have been integrated for high-precision measurements with a grip strength meter. The maximum applicable force is 1’500g with a resolution of 0.1g.
  • The device can be used stand-alone or can be connected to a PC via the USB port to monitor the experiment and record the data.
  • Control unit with internal memory to view and save data. Quick data transfer in .csv or .txt format for data analysis.
  • There is no need of manual calibration since the instrument has an auto-calibration feature before running any trial.
  • The grip strength meter is provided with a stainless-steel T-shaped bar, 2 stainless-steel trapeze bars, a plastic grasping grid, a plastic grasping grid partly blind and a stainless-steel orientable grid (40,3g)
  • The DCA software for signal monitoring is included in with the GSM.

Feature

Benefit

Force-rate monitoring tools (software and LCD display)

It helps the researcher to apply the force with a consistent rate by the PC software and/or the LCD display.

Automatic peak detector

The peak of pull-force is automatically stored in the grip strength meter memory

When pulled by the tail, rodents instinctively grab anything they can to try to stop this involuntary backward movement until the pulling force overcomes their grip strength. When positioned in front of the GSM bar, or trapeze, or grid, the animal grasps at it.

After the animal loses its grip on the grasping bar, the peak amplifier automatically records and stores the peak pull-force achieved by the limbs and shows it on the display.
