title: Digitized Hand Skateboard Based on IR-Camera for Upper Limb Rehabilitation.
abstract: Abnormal upper limb function seriously impacts a patient's daily life. After receiving emergency treatment patient should receive function-rebuilding and recovery training. The objective of this study is to integrate IR-camera, an infrared emitter, with a conventional passive hand skateboard training device for conventional upper limb training and the training process is comprehensively recorded and analyzed. Patients participating in the occupational therapy have a binding band attached to hand skateboard on the table to guide the patient in moving the hand skateboard along the designated path to train the patient's upper limbs. Six people with normal upper limb function participated in the stability test. The device repeatability and test results were verified acceptable. Eight patients with abnormal upper limb function (their upper limb function was damaged due to stroke, MMSE > =27) were trained for 4 weeks. The patient scores in finishing rate and finishing time showed significant improvement. The paired T test results (satisfy p < 0.05 or p < 0.01) between wk-1 and wk-2 are significant. The paired T test results (satisfy p < 0.01) between wk-1 and wk-4 are extremely significant. The new IR-Camera system focuses continuously on the "Figure of eight" curve. The system is light weight and convenient for stroke in home use. The study applies IR-camera technology to the conventional hand skateboard for upper limb training. The experiments show that the hardware of the proposed device no longer delays in response and can result in obvious clinical advances. The proposed device is verified worthy of promotion.
