Objective: To generalize the research status, hotspots, and development trends of amputation-related research.

Methods: The data from 1999 to 2021 were collected from the Web of Science core collection database, and analyzed through bibliometrics software (CiteSpace and VOSviewer) for the dual-map overlay of journals, top 25 references with the strongest citation bursts, top 25 keywords with the strongest citation bursts, and timeline of keywords.

Results: A total of 8,588 literature studies were involved in this study. The United States ranks the first in terms of H-index, total number of publications, and total citations. US Department of Veterans Affairs, Veterans Health Administration, and University of Washington are the major contributors to amputation. Prosthetics and Orthotics International , Archives of Physical Medicine and Rehabilitation , and Journal of Rehabilitation Research and Development are the main publication channels for articles related to amputation. Geertzen JHB, Czerniecki J, and Dijkstra PU are major contributors to amputation. In addition, research on limb salvage treatment and surgical methods for amputation will become a hotspot in the future.

Conclusion: The total number of publications for amputation has generally increased from 1999 to 2021. Our study is beneficial for scientists to specify the research hotspot and development direction of amputation.

Buerger disease is a nonatherosclerotic, segmental inflammatory disease of the occlusive tract, often involving medium-sized muscular and small-diameter arteries and veins of the extremities. If medical treatment is not successful, amputation is inevitable. The aim of this study was to investigate the effect of different kinesiological taping techniques on walking parameters of transtibial amputee with knee extension limitation. Two different kinesiological taping methods (Kinesio Tape and Dynamic Tape) were applied to the transtibial patient with knee extension limitation. Walking performance of patients was assessed with The Biodex Gait Trainer 2. Gait parameters without tape were as follows: average walking speed 0.38 m/s, average step cycle 0.48 cyl/s, average left step length 50 cm, average right step length 43 cm, coefficient of variation 9% at the left, and coefficient of variation 9% at the right. After applying Kinesio Tape and Dynamic Tape, these values were measured as follows: average walking speed 0.50.56 m/s, average step cycle 0.51.56 cyl/s, average left step length 61-60 cm, average right step length 53-54 cm, coefficient of variation 6%-5% at the left, and coefficient of variation 6%-4% at the right side. Dynamic Tape and Kinesio Tape both had positive effects on active joint motion and walking parameters. Regarding walking speed and step length, Dynamic Tape was found to be more effective than Kinesio Tape. Taping methods applied to amputees have positive effects on range of motion, which in return causes improvements on walking parameters.

Background: After amputation, people face challenges including wound healing and decreased functional mobility. Early mobilization in acute hospital care has proved safe, improved function, and sped discharge. Still, loss of a leg complicates standing and early mobilization after amputation. Approaches to early mobilization and rehabilitation after amputation surgery have not been widely studied.

Objectives: To map the evidence regarding early postoperative mobilization after dysvascular amputation. Specific aims included identifying research designs and populations, describing rehabilitation approaches, and identifying gaps within the literature.

Study design: Scoping review following PRISMA-Sc guidelines.

Methods: The a priori scoping review methodology conducted in June 2022 with English language and 20-year limits used the OVID Medline, OVID Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Cochrane databases, and Journal of Prosthetics and Orthotics archive. Reviewer pairs used Covidence software to screen for inclusion (subjects with major lower limb dysvascular amputations, seen immediately postoperatively for hospital-based rehabilitation) with decisions by concurrence. Data for best practice scoping reviews were synthesized for analysis.

Results: Two hundred ninety-six citations were screened, 13 full texts reviewed, and 8 articles included: 2 cohort studies, 3 case-control studies, 2 single-group interventional studies, and 1 case study. There were no randomized control trials or prospective comparison group trials.

Conclusions: Few studies were identified regarding acute rehabilitation after major lower extremity amputation. The limited evidence in this review suggested that early mobilization in the days after amputation was safe with or without use of temporary prostheses, although further research is certainly warranted.

Background: The Jaipur foot is the gold standard in low-cost prosthetics, and the amputee population in low-income and middle-income countries has benefited immensely from this innovation. The ability of the Jaipur foot to mimic the behavior of a regular foot, albeit to a limited extent, has made it a popular choice among clinicians and patients. However, the immense popularity has also hindered further research because minimal efforts have been made to investigate the scope of improvement of the Jaipur foot, particularly with new materials.

Objective: This article focuses on numerical and experimental analyses of various materials for the performance enhancements of the Jaipur foot.

Methods: Contemporary materials are used in finite element analysis to filter the most suitable alternate material for microcellular rubber. The performance of the Jaipur foot fabricated with alternate material is compared with the conventional Jaipur foot through compression testing simulating gait cycle conditions.

Results: The EVA foot showed 1-3 mm higher deformation than the MCR foot during the dorsiflexion or heel strike phases, which indicates an appropriate shock absorption and energy storage capacity in heel striking conditions. In forefoot strike phase or plantarflexion, the EVA foot and MCR foot showed identical behavior in deformations. Replacing the MCR with EVA also resulted in reduced weight of the Jaipur foot by 23%.

Conclusions: The weight reduction can help the amputee to expend less energy, thereby improving patient comfort and walking patterns and hence a more natural performance similar to a regular human foot.

Weight-bearing asymmetry during sit-to-stand (STS) can cause musculoskeletal problems in people with major lower-limb amputation. Does weight-bearing asymmetry differ between individuals with major lower-limb amputation and individuals without amputation? We conducted a systematic review and meta-analysis. We searched PubMed, Cochrane Library, Web of Science, and HAL up to June 2022 using keywords and inclusion/exclusion criteria. Article quality was assessed. Data for population, intervention, weight-bearing asymmetry, and biomechanical analysis were reported. Standardized mean differences (SMDs) were calculated from the outcomes when possible. We included 11 studies (102 people with amputation). Weight-bearing asymmetry was greater in people with amputation than those without amputation (SMD = 1.72 [1.30-2.14] p < 0.00001). It was greater for individuals with transtibial amputation (TTA) and with transfemoral amputation (TFA) than for those without amputation (SMD = 1.20 [0.76-1.65] p < 0.00001 and SMD = 5.32 [4.15-6.50] p < 0.00001, respectively). STS performance time was longer for people with amputation (SMD = 0.52 [0.23-0.81] p = 0.0004) than those without amputation. Trunk motion differed in those with amputation, and lower-limb kinematics differed considerably, especially for people with TFA. Weight-bearing is more asymmetric in people with amputation than in people without amputation. The differences in weight-bearing asymmetry and kinematics during STS between people with TTA and TFA suggest that different strategies are required to improve weight-bearing symmetry: improvements in active prosthetic knees in TFA and rehabilitation focused on weight-bearing in TTA.
