Successful treatment alternatives for chronic pain conditions are limited. One type of chronic pain that can occur is the condition of phantom limb pain, which can occur after the loss of a limb. Many studies have researched the correlation between chronic pain, tactile acuity, and cortical reorganization. Sensory discrimination training has been shown to improve tactile acuity and be beneficial when trying to reduce the intensity and duration of the pain in chronic pain conditions. A device has been developed by the Center for Bionics and Pain Research, and it is intended to train sensory discrimination. How efficiently this device can train sensory discrimination and how much improvements in the tactile acuity in able-bodied participants can be achieved after using the device have been investigated in this study. 16 able-bodied subjects participated in the study. The subjects received five 40 minutes training sessions on five consecutive days. The assessment of the subjects’ tactile acuity was performed before the first training session and after the last training session. The tactile acuity was also assessed after one to two weeks to determine the long-term effect of the training. There were two psychophysical analyses to determine the participants’ tactile acuity, the two-point discrimination test and the monofilament test. The results showed a significant improvement in the two-point discrimination threshold after the five training sessions, thus showing evidence of the improvement in the tactile acuity after using the sensory discrimination training device. There was no significant improvement in the monofilament test.
