“…Low-impedance actuators, for example, can store energy during phases of negative joint work and recharge the leg’s batteries [ 169 ]. There is a tradeoff between cost and function [ 175 ]. While overall expenses related to amputation are reduced thanks to microprocessor-controlled systems, the overall costs remain high [ 137 ].…”

“…Such relationships between the identified user needs have been summarized in Fig. 5 , and are seen across ‘functional’ [ 81 , 134 , 176 – 178 ], ‘ergonomic’ [ 54 , 89 , 110 ], ‘psycho-cognitive’ [ 25 , 39 , 59 , 103 , 109 , 144 , 148 – 150 ] and ‘other’ groups [ 175 , 179 , 180 ]. The category of “Other” needs is less interrelated, which indicates that these relations still remain to be investigated and established.…”

Background The development of bionic legs has seen substantial improvements in the past years but people with lower-limb amputation still suffer from impairments in mobility (e.g., altered balance and gait control) due to significant limitations of the contemporary prostheses. Approaching the problem from a human-centered perspective by focusing on user-specific needs can allow identifying critical improvements that can increase the quality of life. While there are several reviews of user needs regarding upper limb prostheses, a comprehensive summary of such needs for those affected by lower limb loss does not exist. Methods We have conducted a systematic review of the literature to extract important needs of the users of lower-limb prostheses. The review included 56 articles in which a need (desire, wish) was reported explicitly by the recruited people with lower limb amputation (N = 8149). Results An exhaustive list of user needs was collected and subdivided into functional, psychological, cognitive, ergonomics, and other domain. Where appropriate, we have also briefly discussed the developments in prosthetic devices that are related to or could have an impact on those needs. In summary, the users would like to lead an independent life and reintegrate into society by coming back to work and participating in social and leisure activities. Efficient, versatile, and stable gait, but also support to other activities (e.g., sit to stand), contribute to safety and confidence, while appearance and comfort are important for the body image. However, the relation between specific needs, objective measures of performance, and overall satisfaction and quality of life is still an open question. Conclusions Identifying user needs is a critical step for the development of new generation lower limb prostheses that aim to improve the quality of life of their users. However, this is not a simple task, as the needs interact with each other and depend on multiple factors (e.g., mobility level, age, gender), while evolving in time with the use of the device. Hence, novel assessment methods are required that can evaluate the impact of the system from a holistic perspective, capturing objective outcomes but also overall user experience and satisfaction in the relevant environment (daily life).

“…However, due to the differences in the lifestyles of recipients, there have not been many comprehensive experiments and studies comparing the effect of the usage of different materials on the frequency of maintenance and replacement. Indeed, in this matter and practice, complex factors like availability of materials, comfortable fitting for the recipient, and safety of the recipient take precedence over cost comparisons of materials [2] [15].…”

“…However, a prosthesis that can restore function in addition to their cosmetic purposes, i.e., masking the absence of limbs, tends to be costly [1]. On the other hand, the relationship between affordability and functionality is not rigidly proportional and is subjected to other factors such as material choices and fulfillment of the intended purpose [2].…”

REVIEW OF THE COMPLICATIONS IN PROSTHESIS MAKING & SERVICING

Prostheses are intended to restore the human body's appearance and return some functions lost due to the loss of limbs. The prosthesis industry exists for this purpose, as well as the servicing of the prostheses. However, there are complications in the design and installation of prostheses, as well as servicing them. Prosthesis usage is subjected to the specific circumstances of the recipient and is dependent on medical coverage for long-term servicing. The relatively low number of cases involving prostheses compared to other medical cases and the circumstantial differences between these cases prevent in-depth and comprehensive studies of the industry, preventing the establishment of standardized best practices. Despite this, research and development of improvements for recipients' problems continue, utilizing the latest technologies to address technical complications. This article consolidates the present-day complications of prosthesis making and servicing.

Several obstacles must be overcome before preliminary cost-utility analyses (CUA) of prosthetic care innovations can be routinely performed. The basic framework of preliminary CUAs and hands-on recommendations suggested previously might contribute to wider adoption. However, a practical application for an emerging intervention is needed to showcase the capacity of this proposed preliminary CUA framework. This study presented the outcomes of preliminary CUA of the distal weight bearing Keep Walking Implant (KWI), an emerging prosthetic care innovation that may reduce socket fittings for individuals with transfemoral amputation. The preliminary CUAs compared the provision of prosthetic care without (usual intervention) and with the KWI (new intervention) using a 15-step iterative process focused on feasibility, constructs, analysis, and interpretations of outcomes from an Australia government prosthetic care perspective over a six-year time horizon. Baseline and incremental costs were extracted from schedules of allowable expenses. Baseline utilities were extracted from a study and converted into quality-adjusted life-year (QALY). Incremental utilities were calculated based on sensible gains of QALY from baselines. The provision of the prosthetic care with the KWI could generate an indicative incremental cost-utility ratio (ICUR) of -$36,890 per QALY, which was $76,890 per QALY below willingness-to-pay threshold, provided that the KWI reduces costs by $17,910 while increasing utility by 0.485 QALY compared to usual interventions. This preliminary CUA provided administrators of healthcare organizations in Australia and elsewhere with prerequisite evidence justifying further access to market and clinical introduction of the KWI. Altogether, this work suggests that the basic framework of the preliminary CUA of a prosthetic care innovation proposed previously is feasible and informative when a series of assumptions are carefully considered. This study further confirms that preliminary CUAs prosthetic care interventions might be a relevant alternative to full CUA for other medical treatments.
