Objective: The purpose of this study was to investigate the texture discrimination ability of correlated cognitive function by active and passive touch in hemiplegic patients.
Methods: The subject were 15 hemiplegic patients with a mean age of 55.53. When subjects moved their fingers over the surfaces (active touch) and moved under the subject`s stationary finger (passive touch) displayed the same contact time as in the active touch experiments. Tactile task was used a set of five difference texture panel (10cm×10cm×0.5cm), and two conditions of three level (simple, complex, contrast). This approach was based on patterned, randomized texture panel applied to the fingertips for 30 seconds. The subjects ability to identify texture panel by means of active and passive haptic exploration was quantified by the cognitive exercise point to perform the tasks.
Results: There was significant difference in sound side of active touch between low group and high group in the cognition. There was significant difference in simple task of active touch between 21 below group and 22 above group in the hand function. There was significant difference in discrimination task of both touch between 5 below group and 6 group in the Brunnstrom recovery stage. There were difference between sound side and affected side in the passive touch. There were also difference between active touch and passive touch in the affected side.
Conclusion: The present study identify the haptic exploration method on changing cognitive exercise point in the hemiplegic patients. This results suggest that development training method on the recovery of hand function with hemiplegia.
