Lattice Training Digital Testing Rung


A precision tool for measuring force output from the fingers aimed at researchers and academics.

In Stock

The Lattice Training Digital Testing Rung has been designed to meet the needs of sports scientists who require a valid and reliable means of determining the force output of the forearms / finger flexors. The digital rung consists of a standard Lattice Rung, with a high quality, sensitive load cell recording the vertical force that is applied to the hold. 

It is important to note that this is not a consumer product. The Digital Rung’s use – including the collection, processing and interpretation of the data – requires detailed knowledge of testing methodologies and data analysis. Remote introductory training on the setup, collection and interpretation of key data is included. Please note that this does not replace the need for existing knowledge. Contact us to discuss on-going support packages.

The Digital Rung is capable of outputting the force applied to it as an amplified digital serial data signal, collected via USB that may be plotted and recorded using any programme capable of capturing serial data (suggestions for software will be included e.g. serial plotting software or MatLab).

The tests capable of being performed on the Digital Rung include (but are not limited to):

  • Maximum finger flexor force;
  • Rate of force development;
  • Continuous and intermittent tests of force output at maximal or sub-maximal loads (including critical force).

Examples of these sessions and tools for the processing of this data are provided.

If you have any questions please don’t hesitate to get in touch via the contact form.

  • USB cable
  • Examples of key tests and tools for data processing (maximal force, continuous and intermittent tests)
  • 1 hr Skype with the Lattice team to help with setup, talk through the calibration process and demonstrate function (one time – details of ongoing support available on request).


You will need a computer running either Windows or Linux to interface with the rung.
