Touch on predefined areas on the forearm can be associated with specific fingers : Towards a new principle for sensory feedback in hand prostheses
(2019) In Journal of Rehabilitation Medicine 51(3). p.209-216- Abstract
OBJECTIVE: Currently available hand prostheses lack sensory feedback. A "phantom hand map", a referred sensation, on the skin of the residual arm is a possible target to provide amputees with non-invasive somatotopically matched sensory feedback. How-ever, not all amputees experience a phantom hand map. The aim of this study was to explore whether touch on predefined areas on the forearm can be associated with specific fingers.
DESIGN: A longitudinal cohort study.
SUBJECTS: A total of 31 able-bodied individuals.
METHODS: A "tactile display" was developed consisting of 5 servo motors, which provided the user with mechanotactile stimulus. Predefined pressure points on the volar aspect of the forearm were stimulated... (More)

DESIGN: A longitudinal cohort study.
SUBJECTS: A total of 31 able-bodied individuals.
METHODS: A "tactile display" was developed consisting of 5 servo motors, which provided the user with mechanotactile stimulus. Predefined pressure points on the volar aspect of the forearm were stimulated during a 2-week structured training period.
RESULTS: Agreement between the stimulated areas and the subjects' ability to discriminate the stimulation was high, with a distinct improvement up to the third training occasion, after which the kappa score stabilized for the rest of the period.
CONCLUSION: It is possible to associate touch on intact skin on the forearm with specific fingers after a structured training period, and the effect persisted after 2 weeks. These results may be of importance for the development of non-invasive sensory feedback systems in hand prostheses.
