Patient simulator is one of the methods physiotherapists and occupational therapists trainee use to improve their skills. The focus here is on spasticity as part of the upper motor neuron (UMN) syndrome. The rehabilitation process for patients with UMN syndrome and management of spasticity is very important because spasticity will affect function and quality of life. A rehabilitation process requires physicians, occupational therapists and physiotherapists to assess the spasticity level using clinical assessment methods. To engage directly with the patients, the clinicians should have enough skill and experience to reduce risk of injury to the patients. Thus, it is mandatory for the physiotherapists and occupational therapists trainee to go through comprehensive training before they can conduct the therapy session. This paper reveals the research urgency in therapist education tools for upper limb rehabilitation training and points out the significance of having compliance with clinical assessment scales
