Upper Limb Exoskeleton

Stroke is one of the biggest problems of the health system in Brazil and in the world: not only due to high health costs, but also due to the treatment that does not guarantee a complete functional recovery. About 25% of the patients do not survive, and almost half of the survivors have a functional limitation of the upper and / or lower limbs. In the human body, the skeletal structure provides mechanical support for movements. On the shoulder, we find the greatest amount of degrees of articular freedom of the body - it allows arm movements in almost all directions, as well as in different angles. Compromising any of your movements directly affects autonomy in activities of daily living. The tracking of movements of the shoulder girdle and upper limbs accompanied by biomechanical assessments in the performance of activities of daily living provides support for rehabilitation. This measurement, however, is a complex activity due to the number of interdependent joints and movements. The objective of this research is to compare the readings performed on two passive exoskeletons, which measure three-dimensionally the movement of the abduction / adduction and lateral abduction joints. To acquire the signals in the mechanical structure of the equipment, a reading system by a position sensor (encoder) is placed. The acquired signals are treated with a computational tool. The data are presented in real time, with visual feedback on joint movements. In the tests performed, the exoskeleton had no mechanical limitations that prevented the measurement of movements.

Pediatric Use

Sensorless and sensor-based upper limb exoskeletons that enhance or support daily motor function are limited for children. This review presents the different needs in pediatrics and the latest trends when developing an upper limb exoskeleton and discusses future prospects to improve accessibility. First, the principal diagnoses in pediatrics and their respective challenge are presented. A total of 14 upper limb exoskeletons aimed for pediatric use were identified in the literature. The exoskeletons were then classified as sensorless or sensor-based, and categorized with respect to the application domain, the motorization solution, the targeted population(s), and the supported movement(s). The relative absence of upper limb exoskeleton in pediatrics is mainly due to the additional complexity required in order to adapt to children’s growth and answer their specific needs and usage. This review highlights that research should focus on sensor-based exoskeletons, which would benefit the majority of children by allowing easier adjustment to the children’s needs. Sensor-based exoskeletons are often the best solution for children to improve their participation in activities of daily living and limit cognitive, social, and motor impairments during their development.

A new Contourhook terminal device was introduced to the Central Development Unit (CDU) in Australia through the therapist attending the exhibit at the ISPO World Congress, London, September, 1983. Ten upper limb amputees, who were experienced prosthetic users were selected for the evaluation. The patients were asked to attend the CDU to perform selected activities; 7 activities were designed to simulate hand prehension and 17 were bimanual activities of daily living. The activities were performed using the conventional split hook terminal device. The same activities were repeated using the Contourhook terminal device. Performances and patients' comments were recorded. In general the Contourhook was found to compare unfavourably with conventional terminal devices, aspects of the brochure were misleading and all patients preferred their previously worn terminal device.

Population aging in Brazil increases on a large scale due to declining fertility and mortality. This phenomenon can be influenced by several factors (demographic, biological and social), making them determinants for the health conditions of the elderly populations residing in different geographic areas. The present study aims to identify the functional limitation in elderly residents of urban and rural areas of Brazil. This is a descriptive epidemiological study with a quantitative approach. It was evidenced that the functional limitation for activities of daily living   and instrumental activities of daily living are concentrated in the northeast region, mainly in the urban area. The following states presented the highest proportions of daily life activity limitation in urban areas: Alagoas (11.60%), Rio Grande do Norte (10.95%), Pernambuco (10.36%) and Paraíba (9.62%). For activities of daily living in the rural area were found in the states of Paraíba (12.19%), Maranhão (8.93%), Piauí (8.85%) and then Pernambuco (7.24%). Data from the functional limitation for instrumental activities of daily living again highlighted the Northeast region, with the states of Rio Grande do Norte (26.01%), Paraíba (25.96%), Maranhão (25.72%) and Alagoas (24.57%). Lastly, it was verified that the elderly woman exhibits greater proportions of functional limitation in relation to the elderly of the masculine sex, standing out again the northeastern region of the country.

Time Fall

The accidental fall is the major risk for elderly especially under unsupervised states. It is necessary to real-time monitor fall postures for elderly. This paper proposes the fall posture identifying scheme with wearable sensors including MPU6050 and flexible graphene/rubber. MPU6050 is located at the waist to monitor the attitude of the body with triaxial accelerometer and gyroscope. The graphene/rubber sensors are located at the knees to monitor the moving actions of the legs. A real-time fall postures identifying algorithm is proposed by the integration of triaxial accelerometer, tilt angles, and the bending angles from the graphene/rubber sensors. A volunteer is engaged to emulate elderly physical behaviors in performing four activities of daily living and six fall postures. Four basic fall down postures can be identified with MPU6050. Integrated with graphene/rubber sensors, two more fall postures are correctly identified by the proposed scheme. Test results show that the accuracy for activities of daily living detection is 93.5% and that for fall posture identifying is 90%. After the fall postures are identified, the proposed system transmits the fall posture to the smart phone carried by the elderly via Bluetooth. Finally, the posture and location are transmitted to the specified mobile phone by short message.

We describe a strapping device for elevation of the shoulder in patients with thoracic outlet syndrome (TOS). The device was used by 86 patients with TOS whose symptoms had been alleviated by passively raising the shoulder. Symptoms of TOS were classified as proximal, including pain in the shoulder girdle, and distal, in which there were neurological deficits related to the brachial plexus. The device was more effective in patients with distal symptoms: pain disappeared or improved in 67% of patients; numbness in 85%; sensory disturbance in 84%; and motor disturbance in 80%. However, proximal symptoms were relieved in only 65% of the patients. The ability to perform activities of daily living was rated as excellent in 33% of patients, good in 44%, fair in 12%, and poor in 9%. The shoulder orthosis described in this report can counterbalance downward traction on the brachial plexus and reduce the tension on it, thereby relieving symptoms of TOS.

Human Kinematics

The human hand is the most frequently used body part in activities of daily living. With its complex anatomical structure and the small size compared to the body, assessing the functional capability is highly challenging. The aim of this review was to provide a systematic overview on currently available 3D motion analysis based on skin markers for the assessment of hand function during activities of daily living. It is focused on methodology rather than results. A systematic review according to the PRISMA guidelines was performed. The systematic search yielded 1349 discrete articles. Of 147 articles included on basis of title, 123 were excluded after abstract review, and 24 were included in the full-text analysis with 13 key articles. There is still limited knowledge about hand and finger kinematics during activities of daily living. A standardization of the task is required in order to overcome the nonrepetitive nature and high variability of upper limb motion and ensure repeatability of task performance. To yield a progress in the analysis of human hand movements, an assessment of human kinematics including fingers, wrist, and thumb and an identification of relevant parameters that characterize a healthy motion pattern during functional tasks are needed.

The Relationship

Background Previous studies have reported a relationship between upper limb motor function and activities of daily living. However, their relationship after removing the influence of lower limb motor function has not been clarified. Objective This study aimed to investigate the relationship between Fugl-Meyer assessment upper limb and total Functional Independence Measure motor score and between Fugl-Meyer assessment upper limb and each item contained in Functional Independence Measure motor score after eliminating the influence of the motor function of the affected lower limb. Methods This retrospective cross-sectional study included 58 subacute stroke patients. To investigate the relationship between the Fugl-Meyer assessment upper limb and total Functional Independence Measure motor score before and after removing the influence of Fugl-Meyer assessment lower limb, Spearman’s rank correlation coefficient and partial correlation analysis were used. Additionally, the relationship between Fugl-Meyer assessment upper limb and each item of Functional Independence Measure motor score after removing the influence was assessed. Results Before removing the influence of Fugl-Meyer assessment lower limb, Fugl-Meyer assessment upper limb was strongly correlated with total Functional Independence Measure motor score (r = 0.74, p < 0.001). However, it became weak after removing the influence (r = 0.27, p = 0.04). Regarding each item of Functional Independence Measure motor score, Fugl-Meyer assessment upper limb was correlated with grooming (r = 0.27, p = 0.04), bathing (r = 0.28, p = 0.03), dressing upper body (r = 0.33, p = 0.01), dressing lower body (r = 0.31, p = 0.02), and stair-climbing (r = 0.31, p = 0.02) after removing the influence. Conclusion These findings suggest that the relationship between the upper limb motor function and activities of daily living is strongly influenced by lower limb motor function.
