People suffering neurological deficits due to sudden onset of occlusion or rupture of cerebral vessels usually develop

multiple clinical symptoms such as hemiplegia, dysesthesia, difficulty in speech or comprehension or defect of

visual fields after the acute phase. Specifically, functional impairment of the upper extremities is most common in

these patients. It is important to design a suitable training program for individual patient to effectively restore physical

functions. However, the current training protocols often rely on manual and subjective assessment of upper extreme

functions. In this paper we present the implementation of an “Intelligent Stacking Cone System” that was designed

to quantitatively evaluate the functional status of the upper limbs during rehabilitation. The design of a video game

setting with a console emulating the famous whac-a mole game can significantly improve patient participation in the

rehabilitation program. The system is integrated with many optoelectronic position sensors. During the execution,

the system can detect five key timings including the reaction time after a picture prompts, palm grip action, upper

limb remove action, palm release action and upper limb return action. The timing differences between these five

critical activities are used to represent the dynamic status of the upper limb rehabilitation. The therapist could

compare with the past training result to assess explicitly quantified patient progress. Intelligent stacking cone upper

limb rehabilitation system is a new design and method for rehabilitation. This system aims to raise the efficacy and

fun level during diagnostic and therapeutic procedures, thus improve the outcomes.
