<p>Stroke is a common problem that affects approximately 700,000 patients annually in the United States alone and can cause long-term disabilities (Mallory, 2006, p.33). The long-term effects of a stroke can impact on the patient’s ability to use one side of their body. Upper limb, lower limb, postural and communication difficulties are common factors that patients experience after a stroke (Perry, 2004), which can affect the patient’s ability to eat (McLaren, 1997).  After a stroke, the impairment of an upper limb can lead to problems that make it difficult for people to use cutlery, and include poor grip, decreased muscle control, tremors and upper limb weakness (Brackenrige, 2016). Currently, there are some assistive technology (AT) cutlery sets aimed to help patients who have difficulty in eating and muscle control. Several reasons why stroke patients abandon AT cutlery are cost, appearance, and function (Vaes, 2014). However, an experiment (Torrens, 2013) in to adaptive cutlery products and previous research suggest that there is a large space to improve this, such as appearance and function.  AT cutlery sets have been criticized because of their appearance and inferior functions (Torrens, 2013). This then leads to a disconnection between the user and the AT cutlery products, in which the user experiences visible stigma and links the cutlery to an undesirable characteristic (Vaes, 2012). There are some limitations of the current AT cutlery sets that have been identified in the evaluation (Torren & Smith, 2013), such as poor friction material, stereotypical shapes, and skin-tone handle colour. The limitations create an opportunity for the designers to improve the AT cutlery set to be a selected object and a pleasurable product to use in everyday life.  The purpose of this research is to explore how human-centred design can reduce the stigma of using AT cutlery for stroke patients through addressing the appearance and interactions of spoons, forks and knives. The research involves the following steps: observing videos of stroke patients eating, interviewing clinicians, interviewing stroke patients, and iterative design with the supervision of clinicians.  Some of the main issues identified surrounding stroke patient eating and using cutlery include grip weakness, muscle contracture, and difficulty of flexion. Based on the product intervention model for stigma (PIMS) (Vaes, 2014), this study utilized existing research surrounding the evaluation of assistive technology. To help understand each stage of the user needs, previous feedback from health-care clinicians and patients will ensure the validity of ergonomic interventions and stigma strategy as a substitute for traditional cutlery design.  The output of this research includes a set of cutlery as well as assistive components. The design addresses a patient’s difficulty in using cutlery through an adaptive ring to help the patients’ grip. The utensils allow the user to either carry out eating activities at home or in a restaurant.  The feedback from occupational therapists and physiotherapists indicates that the cutlery should accommodate different levels of stroke severity. Based on the findings of literature reviews and feedback, I have focused my design on addressing the stroke patients’ grip weakness, muscle contracture, and difficulty of hand flexion, whilst minimizing stigma, based on the PIMS strategies (Vaes, 2014). The design principle suggests that current cutlery designs with an integrated shape cannot meet all requirements of a stroke patient. Therefore, a combination of additional wearing components needs to be used to help dietary intake.</p>

This paper discusses upper-limb power-assist control using a pneumatic rotary actuator to support shoulder movement and an air cylinder to support elbow movement by agricultural workers lifting a 30 kg rice bag without inducing low back pain. Surface electromyogram (EMG) signals are used as trigger signals, joint support torque is calculated based on the antigravity term of necessary joint torque, estimated based on the dynamics of a human approximated link model. Experimental results demonstrate the effectiveness of proposed power-assist control.

ABSTRACT Objective To examine the frequency of shoulder pain following stroke. Methods Stroke patient function was evaluated using the Functional Independence Measure (FIM) and Scale for Upper Limb Function in Stroke (SULFS). Function scores were examined and compared between the shoulder pain group (SPG) and the no shoulder pain group (No-SPG). Results A total of 58 patients, 22 women (37.9%), were included in this study. The mean patient age was 49.2±10.8 years and study evaluations were done 3.52±2.26 months after stroke. A total of 16 patients (27.6%) were in the SPG and 42 patients (72.4%) were in the No-SPG. The SPG scored significantly lower on the FIM (SPG: 91.06±14.65 vs. No-SPG 114.62 ± 2.27; p < 0.01) and SULFS (SPG median: 2 [range: 1-4], No-SPG median: 5 [range: 1-5]; p < 0.01) than the No-SPG. Conclusion Shoulder pain commonly occurs after stroke and is related to the affected upper limb function and functional independence in stroke patients.

The wavelet transform is an accurate, efficient and efficacious method to improve the quality of the myoelectric signal. Classification of the signal from upper limb using Surface Electromyogram (SEMG) signal has been the matter of extensive research. Number of methods and algorithms have been described by researchers to classify biomedical signals. The main aim of this paper to extract the different coefficient values from the given SEMG data by using Discrete Wavelet Transform (DWT). Afterward, random forest machine learning algorithm was used to identify the different shoulder movement of an upper limb amputee. The combination of wavelet coefficients and random forest exhibited the best performance with 99.2% accuracy for the classification of different shoulder motions. It was found that the different motion can be identified accurately and provide the fundamental information to develop an efficient prosthetic device.

Introduction: Early exercises in the postoperative period of breast cancer are important to prevent motor and functional complications 1,2. However, there are no prospective studies with protocols including specific exercises for patients submitted to breast oncoplastic surgery. Objectives: To assess the amplitude of movement, pain and upper limb function; incidence of dehiscence, seroma, infection and necrosis; and occurrence of reoperation in women in the postoperative period of oncoplastic breast cancer surgery, who underwent protocol of postoperative exercises with restricted shoulder movement for 15 or 30 days. Methodology: We included 60 women with breast cancer submitted to conserving surgery using the oncoplastic technique. They were assessed in the preoperative period and 07, 15, 30, 60 and 90 days after surgery. On the day after the surgery, all patients initiated an exercise protocol limited to 90 degrees, guided by the physical therapist, and performed at home. Two weeks after the surgery, they were randomized in two groups: Amplitude Free Group (30 patients) – liberation of shoulder joint amplitude at the pain threshold or until the sensation of displacement in surgical borders; Limited Amplitude Group (30 patients) – maintenance of shoulder movement restricted to 90º until 30 days after the surgery, when they were also cleared to do free amplitude exercises. Results: there were no differences between groups regarding shoulder joint amplitude, pain and function of upper limbs. In the intragroup analysis, only the Limited Amplitude Group presented upper limb functional index worse than in the preoperative period. There were no differences between groups regarding the incidence of postoperative scar complications nor the need for reoperation. Conclusion: the free amplitude exercises 15 days after the surgery did not have an impact on the movement amplitude nor on the pain, with beneficial effect only in the intragroup analysis, regarding upper limb function. It was considered safe in relation to scar complications.
