Within the Paracanoeing discipline, it is important to ensure that appropriate control is achieved by a paddler with a disability. However, this Paralympic Games discipline has seen very little attention to date. The aims of this study were to understand the kinematic impact to a paracanoeist when not utilizing the use of a prosthetic lower-limb. A kayaker with a uni-lateral transfemoral amputation completed several 200?m maximal efforts both with and without their prosthesis. When the prosthetic limb was removed, there were significant differences found in stroke rate, stroke speed, stroke length and overall power output. Sagittal and frontal video analysis demonstrated the residual limb movements when paddling and indicated where support would be required to improve the kayak’s control. It is recommended that those with lower-limb absence wishing to paddle a kayak competitively utilize the use of a prostheses designed for the kayaking environment that supports the residual limb at both the upper and inner thigh and the distal end. - Implications for rehabilitation
This paper is the first study to investigate both biomechanical and assistive technology-related issues in the new Paralympic Games sport of Paracanoeing. For participants possessing lower-limb absence, a prosthetic limb that is designed specifically for the kayaking environment is recommended when Paracanoeing to maximize efficient propulsion. Use of an ergometer and multiple 2D cameras provides practitioners the ability to optimize both the comfort and fit of a prosthetic limb. Use of an ergometer and multiple 2D cameras provides both athletes and practitioners the ability to optimize the points of human contact within a kayak to ensure comfort and control. 相似文献

Purpose: The purpose of this study is to explore experiences of persons in Nepal using lower-limb prostheses, in relation to specific articles in the Convention on the Rights of Persons with Disabilities that consider mobility, education, health, rehabilitation, and work and employment. Method: Qualitative interviews were conducted with 16 persons using lower limb prostheses. Content analysis was applied to the data. Results: Six themes emerged: The lower-limb prosthesis is essential for mobility and daily life; Limited mobility in challenging terrain and request for reduced pain when using prosthesis; Difficulties in finding and sustaining employment emphasized the importance of vocational training; Appreciation of comprehensive rehabilitation together with other persons with amputations, but covering related costs is a struggle; Satisfied with health care, but concerned that it creates debt and dependence upon others; and finally, Limited ability creates negative self-image and varied attitudes in other people. Conclusion: Persons with lower-limb amputations were restricted by poverty and wanted increased independence. Rehabilitation and prosthetic services in Nepal need to increase proportionally as they contribute to enabling those persons to a better daily life. Prostheses were essential but more advanced technology was requested. Access to education and vocational training has the potential to improve the socio-economic status of those with lower-limb amputations due lack of employment not requiring physical effort. - Implications for rehabilitation
To increase access for persons with lower-limb amputations in Nepal to rehabilitation services, these services need to increase proportionally, and the policy for financial compensation to enable those persons to afford transportation to the rehabilitation center should be implemented. The design and manufacture of the low-cost polypropylene technology for prostheses used in Nepal needs to be improved, directed towards increasing the ability to ambulate on uneven surfaces and hilly terrain, and the ability to walk long distances. Adjustments of employment for persons with physical disabilities in Nepal have the potential to strengthen their socio-economic status. Vocational training programs and educational opportunities for persons with physical disabilities have the potential to improve income-generating employment and need to increase proportionally in Nepal. The policies developed in accordance with the Convention on the Rights of Persons with Disabilities need to be further implemented to decrease existing barriers to access to general health care and rehabilitation and prosthetic services for persons with disabilities in Nepal. 相似文献

Purpose: Post-stroke hemiparesis may manifest as asymmetric gait, poor balance, and inefficient movement patterns. We investigated improvements in lower-limb muscle activation and function during Wii-based Movement Therapy (WMT), a rehabilitation program specifically targeting upper-limb motor-function. Methods: Electromyography (EMG) was recorded bilaterally from tibialis anterior (TA) in 20 stroke patients during a 14-day WMT program. EMG amplitude and burst duration were analyzed during stereotypical movement sequences of WMT activities. Functional movement ability was assessed pre- and post-therapy including 6-min walk test (6MWT), stair-climbing speed, and Wolf Motor Function Test timed-tasks. Results: TA EMG burst duration during Wii-golf increased by 30% on the more-affected side ( p?=?0.04) and decreased by 28% on the less-affected side. Patients who did not step during Wii-tennis had a 16% decrease in more-affected TA burst sum ( p?=?0.047) resulting in more symmetrical activation ratio at late-therapy, with the ratio changing from 3.24?±?2.25 to 0.99?±?0.11 ( p?=?0.047). Six-minute walk and stair-climbing speed improved ( p?=?0.005 and 0.03, respectively), as did upper-limb movement ( p?≤?0.001). Conclusion: This study provides physiological evidence for lower-limb improvements with WMT. Different patterns of muscle activation changes were evident across the WMT activities. Despite the relatively good pre-therapy lower-limb function, muscle activation and symmetry improved significantly with upper-limb WMT. - Implications for rehabilitation
WMT is an upper-limb neurorehabilitation program that also improves lower-limb motor-function. We report a shift towards more symmetrical muscle activation of tibialis anterior on the more- and less-affected sides that were reflected in increased distance walked during the 6MWT. The use of standing during therapy not only improves lower-limb function but also permits larger and more powerful upper-limb movements. Targeted upper-limb rehabilitation can also significantly improve mobility and balance, whether dynamic or static, that should reduce the risk of falls post-stroke. 相似文献

Purpose To investigate the relationship between the classification systems used in wheelchair sports and cardiovascular function in Paralympic athletes with spinal cord injury (SCI). Methods 26 wheelchair rugby (C3–C8) and 14 wheelchair basketball (T3‐L1) were assessed for their International Wheelchair Rugby and Basketball Federation sports classification. Next, athletes were assessed for resting and reflex cardiovascular and autonomic function via the change (delta) in systolic blood pressure (SBP) and heart rate (HR) in response to sit-up, and sympathetic skin responses (SSRs), respectively. Results There were no differences in supine, seated, or delta SBP and HR between different sport classes in rugby or basketball (all p?>?0.23). Athletes with autonomically complete injuries (SSR score 0‐1) exhibited a lower supine SBP, seated SBP and delta SBP compared to those with autonomically incomplete injuries (SSR score?>1; all p?0.010), independent of sport played. There was no association between self-report OH and measured OH (χ 2?= ?1.63, p?=?0.20). Conclusion We provide definitive evidence that sports specific classification is not related to the degree of remaining autonomic cardiovascular control in Paralympic athletes with SCI. We suggest that testing for remaining autonomic function, which is closely related to the degree of cardiovascular control, should be incorporated into sporting classification. - Implications for Rehabilitation
Spinal cord injury is a debilitating condition that affects the function of almost every physiological system. It is becoming increasingly apparent that spinal cord injury induced changes in autonomic and cardiovascular function are important determinants of sports performance in athletes with spinal cord injury. This study shows that the current sports classification systems used in wheelchair rugby and basketball do not accurately reflect autonomic and cardiovascular function and thus are placing some athletes at a distinct disadvantage/advantage within their respective sport. 相似文献

Purpose: Aim of this pilot study was to assess safety and functioning of a microprocessor-controlled knee prosthesis (MPK) after a short familiarization time and no structured physical therapy. Materials and methods: Five elderly, low-active transfemoral amputees who were fitted with a standard non-microprocessor controlled knee prosthesis (NMPK) performed a baseline measurement consisting of a 3?D gait analysis, functional tests and questionnaires. The first follow-up consisted of the same test procedure and was performed with the MPK after 4 to 6?weeks of familiarization. After being refitted to their standard NMPK again, the subjects undertook the second follow-up which consisted of solely questionnaires 4?weeks later. Results: Questionnaires and functional tests showed an increase in the perception of safety. Moreover, gait analysis revealed more physiologic knee and hip extension/flexion patterns when using the MPK. Conclusion: Our results showed that although the Genium with Cenior-Leg ruleset-MPK (GCL-MPK) might help to improve several safety-related outcomes as well as gait biomechanics the functional potential of the GCL-MPK may have been limited without specific training and a sufficient acclimation period. - Implications for Rehabilitation
Elderly transfemoral amputees are often limited in their activity by safety issues as well as insufficient functioning regarding the non microprocessor-controlled knee prostheses (NMPK), thing that could be eliminated with the use of suitable microprocessor-controlled prostheses (MPK). The safety and functioning of a prototype MPK (GCL-MPK) specifically designed for the needs of older and low-active transfemoral amputees was assessed in this pilot study. The GCL-MPK showed indicators of increased safety and more natural walking patterns in older and low-active transfemoral amputees in comparison to the standard NMPK already after a short acclimatisation time and no structured physical therapy. Regarding functional performance it seems as if providing older and low-active transfemoral amputees with the GCL-MPK alone without prescribing structured prosthesis training might be insufficient to achieve improvements over the standard NMPKs. 相似文献

AbstractPrevious studies have proposed that an aerodynamically optimized prosthetic limb could provide performance enhancement for competitive paracyclists. Four different designs of prosthetic limbs were assessed for their impact upon the aerodynamic drag of an elite cyclist with a lower-limb amputation. The pylon area acted as the controlled location for the differences in design between the test prostheses. A validated field test method was used to derive the participant’s total aerodynamic drag when using the prostheses designs. The field test method produced a repeatable experimental process and demonstrated that small changes in form made to the pylon region resulted in measurable differences to the participant’s cycling performance. In addition, statistical significance was obtained between a baseline design and the prostheses prototype with the greatest aspect ratio ( p=?<.05). The magnitude of improvements recorded in this study could potentially influence a rider’s finishing time at international sporting events like the Paralympic Games. - Implications for Rehabilitation
Small changes in form made to a cycling prostheses design can potentially deliver worthwhile performance enhancement. Prosthetists may obtain greater end-user satisfaction by taking a broader approach to sports prostheses design than just fit and biomechanical function alone. This study indicates that other regions of the cycling prosthesis could now benefit from aerodynamic optimization with the aim to further improve paracycling performance. 相似文献

Purpose: To measure self-efficacy in a group of individuals who have undergone a lower-limb amputation and investigate the relationship between self-efficacy and prosthetic-specific outcomes including prosthetic use, mobility, amputation-related problems and global health. A second purpose was to examine if differences exist in outcomes based upon the type of prosthetic knee unit being used. Method: Cross-sectional study using the General Self-Efficacy (GSE) Scale and the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA). Forty-two individuals participated in the study. Twenty-three used a non-microprocessor-controlled prosthetic knee joint (non-MPK) and 19 used a microprocessor-controlled prosthetic knee joint (MPK). Results: The study sample had quite high GSE scores (32/40). GSE scores were significantly correlated to the Q-TFA prosthetic use, mobility and problem scores. High GSE scores were related to higher levels of prosthetic use, mobility, global scores and negatively related to problem score. No significant difference was observed between individuals using a non-MPK versus MPK joints. Conclusions: Individuals with high self-efficacy used their prosthesis to a higher degree and high self-efficacy was related to higher level of mobility, global scores and fewer problems related to the amputation in individuals who have undergone a lower-limb amputation and were using a non-MPK or MPK knee. - Implications for rehabilitation
Perceived self-efficacy has has been shown to be related to quality of life, prosthetic mobility and capability as well as social activities in daily life. Prosthetic rehabilitation is primary focusing on physical improvement rather than psychological interventions. More attention should be directed towards the relationship between self-efficacy and prosthetic related outcomes during prosthetic rehabilitation after a lower-limb amputation. 相似文献

Purpose: The main objective was to assess the change in the functional independence in basic activities of daily living (ADL) following a pre-prosthetic intervention in people with lower-limb amputation (LLA). Secondary objectives were to identify the factors contributing to the success of this intervention, and to analyze the effects on the presence of unmet needs for home adaptation. Method: The ADL intervention was early and pre-prosthetic; it was focused on six self-care activities. Fifty-two adults with LLA, who required assistance in self-care, were included. Functional independence (Barthel) was assessed at baseline and after intervention (T2). Successful intervention was defined as independent performance of all self-care activities. Results: There was a significant improvement in Barthel scores between baseline and T2 in toileting ( p?0.001), bed-chair transfers ( p?0.001), dressing ( p?0.001), bathing/showering ( p?0.001), and feeding ( p?=?0.025). The proportion of homes with an unmet need for adaptation decreased significantly in bathroom ( p?=?0.008) and other internal areas ( p?=?0.031). Intervention was successful for 61.5% of participants. In a multivariate model, age was significantly associated with successful intervention (OR 0.66, 95%CI 0.52–0.83). Conclusions: A short and pre-prosthetic ADL intervention improves functional independence and reduces the need for home adaptation. ADL programs should be included in rehabilitation strategies. - Implications for Rehabilitation
Because basic activities of daily living (ADL) can be seriously compromised after a lower-limb amputation, it is important for this population to improve or maintain their level of independence. A short and pre-prosthetic ADL intervention is an effective method for an early recovery of functional independence in self-care activities and promotes home adaptation. Age is an important determinant of functional recovery, and most subjects can achieve independence in basic ADL regardless of the level of amputation. A pre-prosthetic ADL program should be included in rehabilitation strategies for adults with lower-limb amputation. 相似文献

Purpose: To determine if older adult, novice wheelchair users who drive a power wheelchair with a JoyBar control complete maneuverability tasks in less time and with less error than those who drive a power wheelchair with a standard joystick control. Materials and methods: A parallel randomized controlled trial design conducted at a medical rehabilitation and research centre with ambulatory older adults aged 60 and above ( n?=?27). The intervention was the JoyBar alternative wheelchair control. The primary outcome measure was total time to complete each of the two maneuverability tasks. The secondary outcome measure was total number of errors during each of the maneuverability tasks. Results: An independent, two sampled t-test was conducted and revealed that the JoyBar group took a greater amount of time to complete both maneuverability tasks than the control group ( p?.05). No significant differences ( p?.05) were found in rates of error on either task between the JoyBar and joystick groups. Conclusions: Maneuverability of a powered wheelchair by novice wheelchair users was not improved through the use of the JoyBar when compared to a standard wheelchair joystick, as measured by rates of error and time to complete maneuverability tasks. - Implications for rehabilitation
Clients who are new to powered wheelchair use may perform maneuverability tasks faster, with equivalent accuracy, using a standard joystick versus the JoyBar. Clients who use a JoyBar may require adjustments to the programming of their wheelchair to ensure optimal performance. Additional training may be required to achieve proficiency in maneuverability tasks with a JoyBar versus a standard joystick. 相似文献

AbstractObjective: The aim was to analyse whether there was a change in percentage of long consultations over a 10-year period, and whether individual doctors changed their use of time as they got more experience and specialisation during the same period. Design and setting: This is a registry based study encompassing all consultations in primary care out-of-hours service in Norway in 2008 and 2017. Subjects: For both years all doctors were included in cross sectional analyses. In addition, doctors who participated both years were included in a separate follow-up analysis. Main outcome measures: Long consultations (>20?min) were identified by a time fee in the claims’ database. Results: There were 4610 doctors in 2008 and 5620 in 2017, 904 participated both years. In 2008 a time fee was claimed in 38% of consultations, in 2017 in 47%. Older doctors made less use of the time fee, as did doctors who had many consultations, regular general practitioners, and general practice specialists. The general practitioners who participated both years increased their use of the time fee from 33% to 38% of consultations. Those who specialised in general practice during the 10-year period increased their use of the time fee from 34% to 37%. Conclusions: Experienced doctors have fewer long consultations than inexperienced doctors. Over years there is a strong trend towards increasing the use of time fee during out-of-hours consultations. This trend is only partly offset by increasing the experience of the doctors. - KEY POINTS

Purpose: This study aimed to provide an overview of a) the used measurement instruments in studies evaluating effects on quality of life (QoL), function, activity and participation level in patients with a lower extremity amputation using bone-anchored prostheses compared to socket prostheses and b) the effects themselves. Method: A systematic literature search was conducted in MEDLINE, Cochrane, EMBASE, CINAHL and Web of Science. Included studies compared QoL, function, activity and/or participation level in patients with bone-anchored or socket prostheses. A best-evidence synthesis was performed. Results: Out of 226 studies, five cohort and two cross-sectional studies were eligible for inclusion, all had methodological shortcomings. These studies used 10 different measurement instruments and two separate questions to assess outcome. Bone-anchored prostheses were associated with better condition-specific QoL and better outcomes on several of the physical QoL subscales, outcomes on the physical bodily pain subscale were inconclusive. Outcomes on function and activity level increased, no change was found at participation level. The level of evidence was limited. Conclusions: There is a need for a standard set of instruments. There was limited evidence that bone-anchored prostheses resulted in higher QoL, function and activity levels than socket prostheses, in patients with socket-related problems. - Implications for Rehabilitation
Use of bone-anchored prostheses in combination with intensive outpatient rehabilitation may improve QoL, function and activity level compared with socket prosthesis use in patients with a transfemoral amputation and socket-related problems. All clinicians and researchers involved with bone-anchored prostheses should use and publish data on QoL, function, activity and participation level. There needs to be an agreement on a standard set of instruments so that interventions for patients with a lower extremity amputation are assessed consistently. 相似文献

Purpose: To describe patterns of prosthesis wear and perceived prosthetic usefulness in adult acquired upper-limb amputees (ULAs). To describe prosthetic skills in activities of daily life (ADL) and the actual use of prostheses in the performance of ADL tasks. To estimate the influence of prosthetic skills on actual prosthesis use and the influence of background factors on prosthetic skills and actual prosthesis use. Method: Cross-sectional study analysing population-based questionnaire data (n?=?224) and data from interviews and clinical testing in a referred/convenience sample of prosthesis-wearing ULAs (n?=?50). Effects were analysed using linear regression. Results: 80.8% wore prostheses. 90.3% reported their most worn prosthesis as useful. Prosthetic usefulness profiles varied with prosthetic type. Despite demonstrating good prosthetic skills, the amputees reported actual prosthesis use in only about half of the ADL tasks performed in everyday life. In unilateral amputees, increased actual use was associated with sufficient prosthetic training and with the use of myoelectric vs cosmetic prostheses, regardless of amputation level. Prosthetic skills did not affect actual prosthesis use. No background factors showed significant effect on prosthetic skills. Conclusions: Most major ULAs wear prostheses. Individualised prosthetic training and fitting of myoelectric rather than passive prostheses may increase actual prosthesis use in ADL. Implications for Rehabilitation Arm prostheses are important functional aids for adult acquired major upper-limb amputees (ULAs). Despite being mainly satisfied with their prostheses, reporting their prostheses as useful and showing good prosthetic skills, prosthesis-wearing major ULAs do not use their prostheses for more than about half of the activities of daily life (ADL) tasks carried out in everyday life. In unilateral ULAs, individualised and targeted prosthetic training may increase optimal, active prosthesis use in ADL. Fitting the amputee with myoelectric rather than passive prostheses may increase prosthesis use in ADL, regardless of amputation level.

Purpose: This paper proposes practice guidelines to evaluate community-based rehabilitation (CBR) programs. Method: These were developed through a rigorous three-phase research process including a literature review on good practices in CBR program evaluation, a field study during which a South Africa CBR program was evaluated, and a Delphi study to generate consensus among a highly credible panel of CBR experts from a wide range of backgrounds and geographical areas. Results: The 10 guidelines developed are summarized into a practice model highlighting key features of sound CBR program evaluation. They strongly indicate that sound CBR evaluations are those that give a voice and as much control as possible to the most affected groups, embrace the challenge of diversity, and foster use of evaluation processes and findings through a rigorous, collaborative and empowering approach. Conclusions: The practice guidelines should facilitate CBR evaluation decisions in respect to facilitating an evaluation process, using frameworks and designing methods. - Implications for rehabilitation
Ten practice guidelines provide guidance to facilitate sound community-based rehabilitation (CBR) program evaluation decisions. Key indications of good practice include: ??being as participatory and empowering as possible; ??ensuring that all, including the most affected, have a real opportunity to share their thoughts; ??highly considering mixed methods and participatory tools; ??adapting to fit evaluation context, local culture and language(s); ??defining evaluation questions and reporting findings using shared CBR language when possible, which the framework offered may facilitate. 相似文献

Purpose: Most veterans live for many years after their war-related traumatic lower-limb amputation, which is why understanding which factors influence health-related quality of life (HRQoL) remains important to their long-term management. The objective of this study was to perform a review of the literature to summarize any evidence on the physical and social determinants for HRQoL in veterans with uni- or bilateral lower-limb amputation(s). Method: MEDLINE, EMBASE, PEDro, CINAHL, Scopus and Cochrane databases were searched systematically for eligible studies. Inclusion criteria were: traumatic lower-limb amputation(s), HRQoL outcome and veterans. Physical and social factors that influence HRQoL were extracted. Results: The literature search identified 2073 citations, leading to the inclusion of 10 studies in the systematic review. Physical activity level, sport participation, level of amputation, back pain, years of education, as well as duration and severity of phantom pain were found to be determining factors for HRQoL among veterans with lower-limb amputation. Conclusions: The identified physical and social determinants were similar to those found in civilian traumatic amputees. More high quality research designs, interventions and complex statistical analyses are warranted to identify the physical and social factors that influence the HRQoL of veteran amputees. - Implications for Rehabilitation
Rehabilitation staff should promote physical activity and participation in sport among veterans with lower-limb amputation(s). Level of amputation, back pain severity, years of education, duration of phantom pain and severity of phantom pain have been found to be determining factors for HRQoL and should be taken into consideration when planning rehabilitation programs for veterans with lower-limb amputations. 相似文献

Objective: To analyse the utilization of health care services of people who tested positive for GAD compared to those who tested negative. Setting: A cross-sectional study from the Northern Finland 1966 Birth Cohort. Subjects: A total of 10,282 members followed from birth in a longitudinal study were asked to participate in a follow-up survey at the age of 46. As part of this survey they filled in questionnaries concerning health care utilization and their illness history as well as the GAD-7 screening tool. Althogether 5,480 cohort members responded to the questionnaries. Main outcome measures: Number of visits in different health care services among people who tested positive for GAD with the GAD-7 screening tool compared to those who tested negative. Results: People who tested positive for GAD had 112% more total health care visits, 74% more total physician visits, 115% more visits to health centres, 133% more health centre physician visits, 160% more visits to secondary care, and 775% more mental health care visits than those who tested negative. Conclusion: People with GAD symptoms utilize health care services more than other people. - Key Points
Generalised anxiety disorder (GAD) is a common but poorly identified mental health problem in primary care. People who tested positive for GAD utilise more health care services than those who tested negative. About 58% of people who tested positive for GAD had visited their primary care physician during the past year. Only 29% of people who tested positive for GAD had used mental health services during the past year. 相似文献

AbstractPurpose: To describe an adult population with congenital limb deficiency (CLD) recruited through the National Resource Centre for Rare Disorders (TRS) in Norway: (1) demographic factors, (2) clinical features, (3) pain and (4) use of health care and welfare services. Methods: Cross-sectional study. In 2012, a postal questionnaire was sent to 186 eligible persons with CLD, age 20 years and older. Results: Ninety-seven respondents, median-age 39 years (range: 20–82); 71% were women. The population was divided into two subgroups: (1) unilateral upper-limb deficiency (UULD) n?=?77, (2) multiple and/or lower-limb deficiency (MLD/LLD). About 40% worked full-time, 18% received disability pensions and 64% reported chronic pain, mostly bilateral pain. Grip-improving devices were used more often than prostheses; 23% were previous prosthesis users. Use of health care and welfare services are described. No significant differences were found between the subgroups regarding pain or employment status. Conclusions: Persons with CLD reported increased prevalence of chronic pain, mostly bilateral, and increased prevalence of early retirement. A greater focus on the benefits of the use of assistive devices, the consequences of overuse and vocational guidance may moderate pain and prevent early retirement. Further studies of more representative samples should be conducted to confirm our findings. - Implications for Rehabilitation
Most adults with congenital limb deficiency (CLD) live ordinary lives and experience normal life events. However, several report chronic pain and retire before normal retirement age. In spite of free and accessible prosthetic services, a large fraction chooses not to use prosthesis, more use grip-improving devices for specific activities. These preferences should be acknowledged by rehabilitation specialists. Focus on individually adapted environments, more information about the consequences of overuse, and vocational guidance may moderate pain and prevent early retirement. 相似文献

Goal: This paper aims to provide an overview with quantitative information of existing 3D-printed upper limb prostheses. We will identify the benefits and drawbacks of 3D-printed devices to enable improvement of current devices based on the demands of prostheses users. Methods: A review was performed using Scopus, Web of Science and websites related to 3D-printing. Quantitative information on the mechanical and kinematic specifications and 3D-printing technology used was extracted from the papers and websites. Results: The overview (58 devices) provides the general specifications, the mechanical and kinematic specifications of the devices and information regarding the 3D-printing technology used for hands. The overview shows prostheses for all different upper limb amputation levels with different types of control and a maximum material cost of $500. Conclusion: A large range of various prostheses have been 3D-printed, of which the majority are used by children. Evidence with respect to the user acceptance, functionality and durability of the 3D-printed hands is lacking. Contrary to what is often claimed, 3D-printing is not necessarily cheap, e.g., injection moulding can be cheaper. Conversely, 3D-printing provides a promising possibility for individualization, e.g., personalized socket, colour, shape and size, without the need for adjusting the production machine. - Implications for rehabilitation
Upper limb deficiency is a condition in which a part of the upper limb is missing as a result of a congenital limb deficiency of as a result of an amputation. A prosthetic hand can restore some of the functions of a missing limb and help the user in performing activities of daily living. Using 3D-printing technology is one of the solutions to manufacture hand prostheses. This overview provides information about the general, mechanical and kinematic specifications of all the devices and it provides the information about the 3D-printing technology used to print the hands. 相似文献
