Case Study:  Comparison between traditional gait rehabilitation programs vs robot enabled treatment programs using nCounters Engineering devices

Gait Training on Treadmill and Robot

Five participants in trial studyParticipants:  5
Mean Age:  21 years
Mean BMI:  22kg


Experiment Settings

  • Walking speed:1 – 6 km/h
  • Treadmill (SportsArt Fitness T652M, Mukilteo, WA, USA)
  • Gait exercises on a static robot (Flexbot, Jinho Robot, China)

The vertical ground reaction force (GRF) were measured by nCounters force insoles in which two force sensors were attached to forefoot and heel.

The Results

Walking Tests on Treadmill

Walking tests on treadmill resultsAll of the vertical GRF-time curves exhibited the classic patterns of walking with double peaked configuration.  For walking speed up to 6 km/h, the first peak occurred between 18% and 28% of the total stance time, while the second peak occurred between 70% and 82% of the total stance time.

Gait Exercises on Robot

Gait exercises on robot case study

Most of the GRF-time histories associated with gait speed smaller than 2.2 km/h only exhibited single peak value which located at about 41%-50% of the total stance time.  When the cadence was kept at 40 step/min, the vertical PGRF associated with different stride lengths had a strong positive relationship with the gait speed.  On the other hand, the PGRF associated with constant stride length (i.e. 69 cm) and various cadence values yielded a positive correlation with the gait speed.


The computational results suggest that static robots can be efficiently used to reduce the risk of bone resorption, and hence prevent development of osteoporosis for motor impaired patients.
