Treadmetrix Split-belt treadmills provide the most capable and flexible split-belt instrumented treadmills. The available range of speeds, acceleration, pitch/translation control, measurement area and measurement accuracy are the best available. The split-belt treadmill is well-suited for biomechanics research, clinical research, and sports medicine applications.

Our Split-Belt designs allow for continuous measurements of reaction forces and center of pressure (COP) from each limb during treadmill walking. Each belt can be independently controlled or run in synchronous mode. Belt speed, grade and lateral movement control can be automated via our motion control SDK and easily integrated into an interactive, immersive environment. We have three types of designs available: Non-Incline; Rear-Pivot Incline; and Center Pivot Incline with optional lateral translation control.

Key Features

  • The acceleration/deceleration rates are the highest available in ANY treadmill system (> 35 m/s2)
  • Each treadmill has a measurement surface of 183 cm L x 51 cm W
  • Unique mounting configuration of sensing elements allows excellent center of pressure measurements up to the edges of the treadmill surface
  • Minimal “gap” between each treadmill (< 5 mm of support surface)
  • Treadmills utilizes a modular design, incorporating eight AMTI sensing elements and amplifiers.
  • The location of the sensing elements and force measurement systems are visible at all times, ensuring perfect alignment between motion capture and force platform coordinate systems.
  • The treadmill’s advanced servo motor system ensures that the treadmill speed remains constant under high loads and allows the development of custom speed, acceleration/deceleration profiles.
  • Each treadmill can be controlled independently allowing complete control of the locomotion environment.
