Learning to Perform a New Movement With Robotic Assistance: Comparison of Haptic Guidance and Visual Demonstration
By Liu, Jialin; Cramer, Steven C.; Reinkensmeyer, David J.; Journal of NeuroEngineering and Rehabilitation, Vol. 3, No. 20Publication Date: 2006
Study conducted to evaluate the effectiveness of mechanical guidance provided by a robotic device in teaching movement patterns during rehabilitation as opposed to visual demonstration by the robot alone. A PHANToM 3.0 lightweight haptic robot from SensAble Technologies, Incorporated was used in the study. A total of 20 non-disabled adults ages 18 to 50 participated in the study. The participants held the robot with their dominant hand as it measured hand motion and provide haptic guidance along three-dimensional paths, which were curves on the surface of a sphere. Each participant underwent a visual training protocol and a haptic training protocol. The addition of the haptic input via the PHANToM 3.0 was not found to significantly improve learning when compared to visual demonstration alone. The authors contend, however, that study results support the use of repeated haptic guidance and visual demonstration in teaching movements during rehabilitation. Implication for utilizing these techniques in the practice of stroke rehabilitation are discussed.
