The aim of this study is to develop an adequate part-task trainer occupied with varying levels of severity in spasticity symptoms focusing on the upper limb disorder for occupational therapists. Using the developed part-task trainer, the occupational therapists will have opportunities to repetitively engage in training without patient involvement. The part-task trainer is developed following the structure of human arm articulations with the ability to reproduce the spasticity stiffness. The structured interface programming is built providing three levels of spasticity: mild, moderate and severe. The programming was based on the clinical assessment of spasticity, measuring elbow joint angles and forces exerted by the patients. The recreated spasticity stiffness was evaluated by experienced occupational therapists. Therapists provided positive feedback regarding the mild and moderate level of spasticity leaving further improvement needed in order to reproduce the spasticity at the severe level.

Assessment Scales

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.

The paper presents a comparative study of the kinematic parameters of the upper limbs of one healthy subject and one patient with lateral distal humerus implant. This study aims to identify the movement patterns of the upper limb joints, having a particular interest in elbow joint, due to the patients pathology. Both subjects have been recorded in identical conditions, performing the same exercise what simulates one of the common daily activities. The kinematic parameters which have been analyzed were flexion-extension and abduction-adduction in shoulder joint and flexion-extension of the elbow joint. The joint angles have been averaged per each valid trial and exercise. The comparison of the joint angle variation was performed in terms of normalized time. Standard deviation was computed to evaluate the variability of joint angles. Movement symmetry between left and right arms was evaluated by computing the p-values of the averaged series.

Manual lifting tasks involve repetitive raising, holding and stacking movements with heavy objects. These arm movements are notable risk factors for muscle pain, fatigue, and musculoskeletal disorders in workers. An upper-limb wearable robot, as a 6-DOF dual-arm exoskeleton, which was designed to augment workers’ strength and minimize muscular activation in the arm during repetitive lifting tasks. To adjust the robot joint trajectory, the user needs to apply an interactive torque to operate the robot during lifting tasks when a standard virtual mechanical impedance control structure is used. To reduce overshooting of the interactive torque on the user’s joint, a three-tier hierarchical control structure was developed for the robot in this study. At the highest level, a human arm movement detection module is used to detect the user’s arm motion according to the surface electromyography signals. Then, a Hammerstein adaptive virtual mechanical impedance controller is used at the middle level to reduce overshooting and yield an acceptable value of torque for the user’s elbow joint in actual lifting tasks. At the lowest level, the actuator controller on each joint of the robot controls the robot to complete lifting tasks. Several experiments were conducted, and the results showed that the interactive torque on the user’s elbow was limited and the muscular activations of erector spinae and biceps brachii muscles were effectively decreased. The proposed scheme prevents potential harm to the user due to excessive interactive torque on the human elbow joint, such as related muscle fatigue and joint injuries.

Clinical assessment of the upper limb and hand requires a detailed history of the symptoms, or, in cases of trauma, the circumstances of the injury. Examination should be systematic and guided by a thorough knowledge of anatomy and the likely pathology. Various modalities of imaging can be applied to confirm or characterize the pathology. Each has particular indications and should be applied carefully so as to obtain the most accurate result.

The relevance of the problem of children with upper limb trauma medical rehabilitation is determined by the high frequency elbow joint fractures; the risk of complications development, disabilityc of the patient. A comprehensive medical rehabilitation program assumes a personalized approach and a differentiated prescription of physical factors, depending on the time period of rehabilitation. Early physical rehabilitation is a key link in the complete recovery of the function of a patient’s limb with damage to the elbow joint. The purpose of this work is to analyze literature and summarize the results of our own research to determine the optimal approaches and methods for medical rehabilitation of children with upper limb injury. The medical rehabilitation program includes various methods of kinesiotherapy, robotic mechanotherapy, massage, a wide range of apparatus physiotherapy to improve the trophism of the periarticular tissues, to maintain mobility in joints free from immobilization; gain of the full range of motion in the damaged joint; normalizing tone and strengthening the muscles of the upper limb. Medical rehabilitation of children with elbow joint injury is carried out from the earliest stage, in stationary conditions, during the period of immobilization. The rehabilitation measures continue in outpatient and polyclinic conditions, during the entire period of immobilization (2–4 weeks) and then in the post-immobilization period until the limb function is fully restored. It is necessary to monitor the main indicators of the function of the upper limb during the entire period of rehabilitation to assess the effectiveness of rehabilitation measures, objectify the course of the rehabilitation process and the continuity of rehabilitation programs. Definition of the tasks of medical rehabilitation, differentiated for each stage; the choice of modern, pathogenetically grounded rehabilitation technologies with an assessment of their effectiveness contribute to a significant increase in the effectiveness of comprehensive rehabilitation programs for children with upper limb trauma.
