AMTI's force-sensing treadmill uses an innovative tandem belt design that allows subjects to maintain a normal gait and eliminates many issues inherent to side-by-side, split-belt treadmills.
The rugged design and construction are built for the long run.
With an AMTI tandem treadmill, subjects can walk naturally with no need to maintain their positions medial-laterally or straddle the belt split that runs down the center of the treadmill. Heel strike occurs on the front belt and the foot naturally translates to the rear belt for toe off as the subject walks. With only a 1 mm clearance between the two belts, they function as one continuous belt while preventing the data problems that occur during the double support phase of walking.
Mounting Options include, above Floor Mount or Recessed Floor Mount. When recessed into the floor the handrails can be removed allowing the treadmill force platforms to be used as stationary force platforms.
Belts can be controlled synchronized or independently from each other. The Computer controls the belt speed and angle of inclination. The High-performance digital motor controllers provide smooth and reliable control.
Tandem belt design eliminates the requirement for the test subject to remain centered on the medial-lateral axis. The 14 mm diameter low profile rollers driving the belts and a 1 mm space between belts, makes two belts feel like one continuous belt.
The Tandem Belt design eliminates loss of data caused by “double support” during walking. In addition, the Low-mass composite sensing elements within the force plates are located near the belt surface.
The treadmill has a non-inclined height of only 11 inches with no protrusions on the sides or ends. The end-to-end treadmill can be used as two floor-mounted force plates when incorporated into a walkway with its handrails removed. Control electronics are built into the treadmill; force plate and control cables are the only connections required between the treadmill and the operator area.
A six-axis AMTI force plate is located under each belt to record the ground reaction forces (Fx, Fy, Fz) and moments (Mx, My, MZ) generated by the subject. The force plates are an integral part of the treadmill design and each force plate entirely supports its own treadmill/drive motor assembly. High performance digital motor controllers and included software provide users with an intuitive interface for control of treadmill inclination, belt travel direction and belt speed up to 20 km/h. The extensive capabilities of the Tandem Treadmill make it an ideal method for studying both walking and running under level, uphill and downhill conditions.
The Vertical Force Plate capacity is 8800 N ( 2000 pounds) and the Horizontal capacity is 4500 N (1000 pounds).
The Speed can be adjusted from 0 to20 kilometers per hour in increments of 0.06 kilometer per hour. The belt direction is reversible for uphill and downhill walking or running.
The Integrated Force Platform resonant frequency in above 300 Hz (Fx, Fy End-to-End model) and has a linearity of better than +/- 0.2 % FSO
The Analog Outputs and Digital Data (USB) are available for each force platform through supplied MSA-6 amplifiers.
The Handrails are 91 cm high and 91 cm apart. The Side and handrails are removable. The total belt coverage is 148 (L) X 66 (W) cm. Each belt measures 74 (L) X 66 (W) cm. The overall dimensions including handrails 203 (L) X 112 (W) X 125 (H) cm.
