The purpose of this scoping review was to investigate the effects of 3-dimensional (3D)-printed prostheses. Articles published up to August 19, 2023, were searched in the PubMed, Cochrane Library, Embase, and Scopus databases. The search terms used were "3D printed prosthesis," "3D printed prostheses," "3D printed prosthe*," "3D printed artificial arm," "3D printed artificial leg," "3D printing prosthesis," "3D printing prostheses," "3D printing prosthe*," "3D printing artificial arm," and "3D printing artificial leg." This review included studies that applied 3D-printed prostheses to upper- or lower-limb amputees. Case reports, conference abstracts, presentations, reviews, and unidentified articles were excluded from the analysis. A total of 937 articles were identified, 11 of which were included after confirming eligibility through the title, abstract, and full text. The results indicated that the 3D-printed prostheses demonstrated the ability to substitute for the functions of impaired limbs, similar to conventional prostheses. Notably, the production cost and weight were reduced compared with those of conventional prostheses, increasing patient satisfaction. The use of 3D-printed prostheses is expected to gain prominence in future clinical practice. However, concerns regarding the durability of 3D-printed prostheses have increased among users. Therefore, there is an ongoing need to explore highly durable materials that can withstand the weight of the user without breaking easily. In addition, advancements are required in technologies that enable the depiction of various skin tones and the production of smaller-sized prostheses suitable for clothing.

Objective: The aim of this study was to assess the cultural adaptation and validation in Italian of the Seated Postural Control Measure for Adults 2.0 (SPCMA 2.0).

Methods: The original scale was translated and culturally adapted from French to Italian using the "Translation and Cultural Adaptation of Patient Reported Outcomes Measures-Principles of Good Practice" guidelines. Its internal consistency and test-retest reliability were examined. Its concurrent validity was evaluated using Pearson correlation coefficients with the Italian version of the Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Results: Fifty-nine people were evaluated and re-evaluated after 48 h. Most of the items and subscale totals were stable in the 2 evaluations as they reported an intraclass correlation coefficient value of >0.77. The test-retest analysis of the dynamic evaluation was performed on the same patients 48 h apart. The analysis for construct validity showed statistically significant correlations with Wheelchair use Confidence Scale and Wheelchair Skills Test 4.2.

Conclusions: Seated Postural Control Measure for Adults 2.0 is one of the few tools that allow researchers to perform a quantitative and standardized posture assessment in a cost-effective and time-saving way. Furthermore, it has been demonstrated that it is an easy-to-administer scale and requires readily available tools. The limitations of this study highlighted above and the need to use quantitative and qualitative tools in clinical practice imply the need to conduct future studies.

Background: Stretching exercise is generally used for improving flexibility. However, its application to promote orthotic treatment for patients with adolescent idiopathic scoliosis (AIS) remains unknown.

Objective: This study was to explore the effect of pre-orthosis stretching exercises on spinal flexibility and initial in-orthosis correction for the patients with AIS.

Study design: A pilot-controlled study.

Methods: An experimental group (EG) of 13 subjects (10 girls and 3 boys) with AIS allocating to self-stretching exercises and a control group (CG) of 19 AIS subjects (14 girls and 5 boys) with no stretching before orthosis fitting were recruited. The spinal flexibility of the EG was evaluated with an ultrasound imaging system and physical measurements. The initial in-orthosis correction rates between the 2 groups were compared with the independent t test, and the correlation analysis between the spinal flexibility measured from ultrasound images and physical measurement was performed with the Pearson correlation test.

Results: The initial Cobb angle of EG and CG were 25.70° ± 7.30° and 28.09° ± 5.58°, respectively. No significant difference was observed between the initial in-orthosis Cobb angle of EG (11.13° ± 6.80°) and CG (15.65° ± 9.10°) (p = 0.06). However, the spinal flexibility after stretching exercises was improved (p < 0.001), and the spinal flexibility changes measured with ultrasound and physical forward-bending method were significantly correlated (r = 0.57, p < 0.05).

Conclusion: Stretching exercises before orthotic treatment could improve the spinal flexibility but did not cause a better in-orthosis correction. A study with a larger sample size and longer follow-up period should be conducted to investigate the long-term effect of stretching exercises.

Background: The role of the orthotist in early gait rehabilitation after stroke in the United Kingdom is currently poorly understood.

Objectives: The objective of this study was to capture current opinion and practice of orthotists on their role in early stroke gait rehabilitation in the United Kingdom.

Methods: An anonymous web-based cross-sectional survey was developed and distributed to Health and Care Professions Council-registered orthotists by the mailing list of the British Association of Prosthetists and Orthotists professional body in the United Kingdom. Survey items were multiple-choice, Likert scale, or open-ended questions to explore the experiences and opinions of orthotists in early poststroke gait rehabilitation.

Results: Responses were received from 56 participants. Orthotists reported having regular contact with patients who had a stroke within their usual clinical caseload. Multidisciplinary care was not typical with 46% respondents "rarely" seeing patients who had a stroke in joint assessment with another clinician. Confidence in managing lower limb gait difficulties was high, with 89% of orthotists feeling able to recommend a lower limb orthotic treatment. Ninety-eight percent (n = 55) of respondents agreed that orthotic assessment should be an essential element of gait re-education after stroke; however, orthotists reported limited involvement within early stroke rehabilitation.

Conclusion: UK orthotists surveyed in this study report that orthotic treatment is an important aspect of early gait rehabilitation after stroke. Respondents report barriers to multidisciplinary working, which may affect outcomes in this patient group.

The selection of the leading limb during gait initiation in individuals with unilateral transtibial amputations can significantly affect various biomechanical parameters. However, there is currently no established recommendation for the suitable leading limb in this population. The systematic review was aimed to propose a preferred leading limb for gait initiation in individuals with unilateral transtibial amputations based on biomechanical parameters. Databases including Google Scholar, PubMed, Science Direct, and ISI Web of Knowledge, were searched. The first selection criterion was based on abstracts and titles to address the research question. A total of seven studies were included in this review, and the Downs and Black's checklist was used by three researchers to assess the risk of bias. The review included a total of 61 adults with unilateral transtibial amputations, with a mean age range of 41 to 64.43 years. The confidence level of the included studies was poor, and the observational cohort was the most common study design (n = 5). Most of the studies were not replicable. Four of the included studies recommended the prosthetic limb as the preferred leading limb. Individuals with unilateral transtibial amputations may experience biomechanical benefits, including a more normal center of pressure path, reduced limb loading, and increased ankle energy generation, when leading with their prosthetic limb during gait initiation. However, further research is necessary to establish a more conclusive recommendation for the preferred leading limb in this population.

Prosthetic alignment is a highly subjective process that is still based on clinical judgments. Thus, researchers have aimed their effort to quantify prosthetic alignment by providing an objective method that can assist and guide prosthetists in achieving transtibial (TT) prosthetic alignment. This systematic review aimed to examine the current literature on TT prosthetic alignment to scope the qualitative and quantitative methods designed to guide prosthetists throughout the TT prosthetic alignment process as well as evaluate the reported instruments and devices that are used to align TT prostheses and their clinical feasibility. A literature search, completed in June 2022, was performed using the following databases: Web of Science (Clarivate), SCOPUS (Elsevier), and Pub Med (Medline) with searching terms focusing on TT, prosthesis, prosthetist, prosthetic alignment, and questionnaires, resulting in 2790 studies being screened. Twenty-four studies have used quantitative methodologies, where sensor technologies were found to be the most frequently proposed technology combined with gait analysis tools and/or subjective assessments. A qualitative method that assists prosthetists throughout the alignment process was not found. In this systematic review, we presented diverse methods for guiding and assisting clinical decision-making regarding TT prosthetic alignment. However, most of these methods considered varied parameters, and there is a need for elaboration toward standardized methods, which would improve the prosthetic alignment clinical outcome.

Women living with limb loss (amputees) have unique needs that increase during pregnancy. Comfort, pain, and activity are exponentially compromised. Changes in mass and altered center of gravity increase the likelihood of falls and compromise safety for the mother and unborn baby. Subjective and physical functional performance measures data was collected through 2 separate pregnancies on a 36-year-old woman with a right transfemoral amputation. Physiological changes during pregnancy effected comfort, pain, and functional performance. Clinical practice guidelines for prosthetic management should be established to include protocols such as adjustment schedules, specialized socket design, and necessary component changes throughout the course of pregnancy.
