Critical Challenge

Background and Aim: Although upper limb myoelectric prostheses can offer improved functionality and dexterity over body-powered systems, abandonment rates remain high. User dissatisfaction in comfort and control are among the top contributors. The design of the prosthetic socket must be comfortable, while maintaining contact of control electrodes with the residual limb throughout the day. We present a myoelectric socket design that provides user-adjustable compression over electrode control sites to promote consistent control, while maintaining comfort and fit. Technique: A cable tensioning system was threaded through a series of paneled windows in the socket wall over electrode sites. Adjusting tension provided tuning of electrode contact. Discussion: A case study of a single transhumeral prosthetic user with a follow-up interview 11 months post delivery suggests that our adjustable design has the potential to address control and comfort challenges, critical factors in myoelectric prosthetic use, and abandonment. Clinical relevance Achieving consistent electrode contact with muscle control sites in traditional rigid sockets is a critical challenge for myoelectric prostheses. We present a unique solution via user-adjustable electrode contacts built into the socket.

This study was designed to investigate the satisfaction level of young users of myoelectric prostheses who received an upper limb myoelectric prosthesis, to assess their dropout rate and to identify which factors influence the use or non-use of the upper limb myoelectric prosthesis in the eastern part of Quebec (Canada). The users were fitted between 1990 and 1999 at the Quebec Rehabilitation Institute, a major rehabilitation centre located in the province of Quebec. This rehabilitation centre provides cutting-edge expertise not only for the eastern part of Quebec, but also across the entire province, because it is one of only two highly specialised centres serving all of Quebec.A literature review was completed to compile the results obtained in other rehabilitation centres and to identify factors influencing the use or non-use of paediatric upper limb myoelectric prostheses. The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) was used in order to assess the degree to which the children were satisfied with their prostheses.Eighteen (18) children were fitted and trained to use an upper limb myoelectric prosthesis. A total of 10 children and parents agreed to participate. Some 80% of participants said that they were satisfied with their prostheses. A dropout rate of 53% for the overall group (participants and non-participants) seems high compared with that of other studies. Recommendations linked to factors identified in the literature are made. The authors conclude that a multidisciplinary team and structured training and follow-up can improve the clinical results pertaining to all the factors proposed in the literature.

Background and aim: Thermal related problems with prostheses are common complaints of amputee people. This article aims to introduce a thermoregulatory technique as a potential solution for those problems in prostheses wearers. Technique: A smart thermoregulatory system was designed, manufactured, and installed on a phantom model of a prosthetic socket. It captured temperature data from 16 sensors positioned at the interface between the phantom model and a silicone liner and used their average for comparison with a defined set temperature to select required heating or cooling functions for thermal equilibrium. A thin layer of Aluminum was used to transfer temperature between thermal pump and different sites around the phantom model. Discussion: The feasibility of this thermoregulatory technique was confirmed by its ability to provide thermal equilibrium. Further investigations to improve the design of thermoregulatory system are necessary including temperature transfer element and power consumption based on thermal capacity and thermal inertia of the residual limb. Clinical relevance The smart thermoregulatory system by providing thermal equilibrium between two sides of a prosthetic silicone liner can control residual limb skin temperature and sweating. Consequently, it can improve quality of life in amputee people.

Abstract Introduction/Objective DMAIC (an acronym for Define, Measure, Analyze, Improve and Control) refers to a data- driven improvement cycle used for improving, optimizing, and stabilizing business processes and designs. Our goal was to utilize DMAIC principle of six sigma quality to improve histology slide quality. Methods/Case Report We “defined” the problem as suboptimal quality in endometrial biopsy slides (defects). Utilizing the DMAIC principle and adhering to a strict timeline, the defects found during baseline slide quality review were “measured” by linking the defects to specific histology competencies, which were addressed systematically for process improvement (PI). After PI, a follow up review (“improve” and “control” phases) was carried out to identify measurable outcomes as a testament to quality. Results (if a Case Study enter NA) During the problem “measurement” phase, the defects found in the baseline review of 175 slides were linked to four specific histology competencies (fixation, embedding, cutting, and staining). Processing was excluded as it is completely automated and standardized. Our analysis showed that 83.3 % of defects were linked to embedding (“tissue too dispersed”). As embedding competency depends on the size and nature of the tissue (e.g. mucus and blood admixed with tissue), grossing competency was also addressed along with embedding at the respective workstations. Recommendations were offered to the grosser, embedder, and cutter to reduce variables during the “improvement” phase. Follow up review was done on 196 slides. The number of defective slides decreased and the defects that linked to “tissue too dispersed” had an overall improvement of 91.3%. Once the PI is proven to be effective, in service to histotechnology personnel biannually were also offered during “control” phase. Conclusion We have demonstrated successful methods for improving histology slide quality utilizing DMAIC principle of quality improvement by six sigma methodology DMAIC principle can be creatively adapted in laboratory practice management to enhance quality.

During the design and fabricating processes of a prosthetic socket, in order to avoid the impair on the pressure-relief areas of the residual limb, such as tibia, the shape of duplicated plaster mold of the residual limb that is used to make the socket should be modified. The study focused on developing an algorithm that employs the techniques of reverse engineering, theories of B-spline and lofted surface, and knot insertion method to modify the shape of a residual limb. Once the regions of PT/PR areas of a residual limb have been specified, the selected scanned points are then transferred to the prototype system developed in this study to implement the required modification. A demonstrated case study has verified the algorithm that can automatically meet the required shape change of that specific residual limb. Based on the shape modification algorithm, an automated prosthetic socket design system that is being developed would then be more feasible.

Abstract The most common causes of upper-limb amputations include traumatic etiology and malignity, followed by peripheral vascular diseases. Prosthetic fitting along with conducting a rehabilitation program provide the greatest possible degree of independence to the upper-limb amputees in performing their daily tasks, occupational, recreational and work activities. Despite recent advance in strategies of design and control, the lack of sensory feedback is, according to patients, one of the most important characteristics lacked by commercial myoelectric prostheses. This reason has led to the need for the development of comprehensive prosthetic part which would provide intuitive control and realistic sensory feedback to the amputees enabling them thus to more easily accomplish the tasks which are essential for easier performance of activities of daily life. Electromyography, and recently, electroneurography signals have been used for the development of more efficacious upper-limb prosthetic control. Several recent studies have demonstrated the efficacy of homologous and somatotopic approach in upper-limb amputees, by applying implanted and surface electrodes. This work presents novel methods for effective bidirectional control of myoelectric prostheses in patients with upper-limb amputations using motor control and sensory feedback. The above-mentioned approaches are applicable and have good prospects in further clinical use. The intraneural, extraneural and surface approach can be more or less applicable depending on the etiology and the level of amputation. From a clinical point of view, various approaches should be combined for obtaining more efficient control of bidirectional prostheses and corresponding sensory feedback.

In the current report, the conditions, procedures and results of a treatment with medical hypnosis are presented. The single case study is the result of a cooperation between ophthalmology and medical hypnosis. After a surgical adverse occurrence led to different complications and an escalation of intraocular pressure, the ophthalmologic treatment of a patient was supplemented by medical hypnosis. Measurements of intraocular pressure at different times before and after the hypnosis treatment made it possible to quantify the effects of the hypnosis intervention. In a 17-month follow-up period, 43 measurements were taken and control results were obtained. After intraocular pressure escalations up to a damaging degree within the initial situation, the measured values stabilized at a low average intraocular pressure with no further escalations. Besides a stabilized lower intraocular pressure, active coping and relieved feelings on the part of the patient were obtained.
