ABSTRACT Introduction There are limited examples in the literature of detailed orthotic management related to triplanar control of the ankle-foot complex. The aim of this case report was to describe year-long use of an ankle-foot orthosis–footwear combination (AFO-FC) augmented with a talar flange that aimed to stabilize the subtalar joint during gait in an individual with poststroke hemiplegia who presented with both knee hyperextension and an unstable subtalar joint. Materials and Methods A 40-year-old woman 1-year poststroke with right hemiplegia presented with right equinovarus and knee hyperextension, with complaint of pain in the ankle and knee. Her right talocrural joint measured 15° plantarflexion with clinically significant inversion instability. Results A right solid AFO-FC, designed using published algorithms, was provided. In addition, a talar flange modification was incorporated to control subtalar inversion. During year-long use of the AFO-FC, the patient was able to return to community ambulation without pain. Successful orthotic intervention required that the device met not only biomechanical goals but also broader patient goals, which changed over time. Therapy with the device was also important for successful orthotic intervention. Conclusions This case illustrates use of a talar flange in an AFO-FC to provide triplanar control of the ankle-foot complex and improve gait in a person poststroke.

ABSTRACT Introduction Children with achondroplasia experience numerous impairments in body structure and function, including hypotonicity, weakness, joint laxity/hypermobility, skeletal malalignment, and delays in gross motor development. Atypical patterns of movement are often used to compensate for short limbs, weakness, laxity at the joints, and bony malalignment. As a result of these atypical patterns, pain and self-restricted movement frequently begin at a young age. Surgical interventions are the general recommendation to address progressive deformity and resultant pain. Lower-limb bracing to address alignment and motor control in children with other diagnoses that include hypotonia has had positive results, including improved alignment and gross motor skills, but has not been explored in children with achondroplasia. Materials and Methods A 3-year-old child with achondroplasia participated in an intervention using a neoprene knee orthosis with hyperextension resistance at the knee combined with a play-based, proprioceptive-intensive home exercise program. We hypothesized that the knee orthosis would increase proprioceptive input, improve alignment, and have a positive effect on gross motor skill acquisition and refinement. Early training may also have a positive impact on potential future pain and disability. Results Improvements in alignment and motor control were seen in this child after 12 weeks of this intervention but were not initially sustained. After an additional 6 weeks of intervention, significant progress was demonstrated in lower-limb alignment and motor control, as evidenced by independent use of proper movement patterns. Delay in gross motor skill was reduced from 27% to 22%. Discussion Motor skills training in proper alignment with aid of neoprene knee orthosis resulted in positive gains for a 3-year old with achondroplasia. Conclusion This intervention may be helpful for other children with achondroplasia who experience hypotonia, malalignment, and atypical movement patterns. Sufficient amounts of practice and intensity are recommended for permanent motor learning to occur.

ABSTRACT Introduction Amputation is one of the oldest surgeries known to the human race. The principles of amputation in children are different than in adults. Common indications for amputation include congenital, traumatic, infection, malignancy, vascular, and other pathology. Improper prosthetic fitting or inability to use the most modern available prosthesis can lead to dissatisfaction and compromised high-level function. The aim of this study was to assess residual limbs for compatibility to fit the most modern prosthetic components. Methods This study is a retrospective review of medical records of patients who underwent amputation between the pelvis and midfoot before 18 years of age. Age, sex, etiology, and level of amputation were recorded. A senior certified prosthetist graded the limbs based on limitations the residual limb imposed on options for the highest functioning modern prosthetic components. Results Sixty-one patients were identified (35 male, 26 female) with a mean age at assessment of 17.35 years (range, 1.86–35.35 years). Congenital causes and tumors were the most common etiology. Amputations around the ankle were most common (25), followed by transtibial (20). There were 59% grade 1 limbs with no restrictions to component options, 28% grade 2 with moderate restrictions, and 13% grade 3 or severely limited component options due to the residual limb. Most grade 1 residual limbs were transtibial or proximal. Amputations distal to transtibial were of all grades. Conclusions The choices for optimal high-level prosthetic components are much less limited for transtibial amputation than more distal amputations leading to potentially less high-level prosthetic function. Managing the residual limb length and prosthetic fitting ability is an important element in pediatric amputations if the goal is to fit mature young adults with the highest functioning level prosthetic components.

ABSTRACT Introduction This case report describes orthotic design using computed tomography and three-dimensional printing technology combined with traditional orthotic modalities in a newborn patient with chondrodysplasia punctata and cervical spinal stenosis. At day 5 of life, the infant was referred for fitting with a prefabricated cervical collar. Because of the infant's unique stature and small size, traditional prefabricated devices could not be used. The spinal instability and critical nature of the infant prevented traditional methods of orthosis fabrication. A multidisciplinary team used imaging, 3D printing technology, and traditional orthosis fabrication methods to construct a cervical thoracic lumbosacral orthosis (CTLSO). Materials and Methods Using computed tomography scans, data-segmenting software, and a 3D printer, a life-sized model of the patient's upper body was constructed. Traditional plaster molding and high-temperature orthoplastic techniques were used to fabricate a custom cervical thoracic lumbosacral orthosis for spinal stabilization, necessary for safe patient transport and handling. Results The custom orthosis demonstrated proper fit and stability, as evidenced by postfitting scans. With orthosis in place, needed care could be provided to the patient more safely and efficiently. In addition, the infant could be held by the caregivers, increasing parental/infant bonding. Conclusions Technological advances, including the ability to use computer tomography scans in combination with three-dimensional printers, can be a safe and effective option in situations of difficult orthosis fabrication for medically fragile patients.

ABSTRACT Introduction Adjustable-volume prosthetic sockets have been available for many years to address residual limb volume changes, although little research has been conducted regarding their efficacy. As such, prosthetists are guided by patient preference, personal experience, and professional perception. The purpose of this study was to explore clinician perceptions and experiences fitting adjustable-volume prosthetic sockets. Materials and Methods An anonymous online survey was distributed to certified prosthetists. The survey contained questions about prosthetists' demographics, whether they had previously fit an adjustable-volume prosthetic socket, whether these fittings were successful, and what challenges they experienced. Those who had not previously fit adjustable sockets were asked what barriers had prevented them from doing so. Results A total of 221 certified prosthetists completed the survey. Of the 195 eligible respondents, 82% had experience in fitting adjustable prosthetic sockets. The most commonly fit socket styles were the RevoFit (n = 123), Socket-less (n = 67), and Infinite (n = 66) sockets. Prosthetists had varied success with the different socket styles, with the RevoFit being the most successful, and the Infinite and Socket-less sockets the least successful. Respondents most frequently noted increased bulk (93% of respondents; n = 181), complicated fabrication (72%; n = 141), and poor cosmesis (65%; n = 127) as challenges faced when fitting adjustable-volume sockets. Some respondents felt these sockets were a useful clinical tool; however, common themes regarding clinical perception of adjustable sockets included issues with cost/reimbursement and appropriateness for only a subset of the population of individuals with amputation only. Other respondents felt that adjustable sockets were either not adequate for clinical use or required improvements before their use would be beneficial. Conclusions There is no majority opinion regarding the benefits and challenges of adjustable sockets among prosthetists. In general, prosthetists feel that adjustable sockets can be used as one of the various tools to accommodate complicated lower-limb fittings. Additional work is needed to provide clinicians with a best practice guideline for providing adjustability within lower-limb sockets. Clinical Relevance The study showed that prosthetists feel that adjustable sockets can be one of the tools used for complicated lower-limb fittings. Additional work is needed to develop a best practice guideline for providing adjustability in lower-limb sockets.

ABSTRACT Introduction Despite successful bracing for adolescent idiopathic scoliosis (AIS), some curves progress after brace cessation. The purpose of this study was to identify the incidence, rate, and risk factors for progression after successful brace management of AIS. Materials and Methods Patients treated with orthoses for AIS were prospectively enrolled at brace initiation, followed through successful brace completion and, on average, for 33 months (range 12–95) after brace cessation. Inclusion criteria were curves 25° to 45° and Risser 0 to II at brace initiation with cessation at Risser IV with curves measuring <50°. Exclusion criteria were cessation before Risser IV or curve progression >50° during bracing. Demographics and radiographic measures were collected. Brace compliance was measured using Thermachron temperature sensor. Postbrace progressors were compared with nonprogressors using Mann-Whitney U test, Fisher exact test, and two-sample t-test. Results Eighty-five patients who completed bracing with final curves <50° were followed after brace discontinuation >1 year. Twenty-seven/85 (31.8%) progressed postbracing to surgical curve magnitude >50° (n = 12) or progressed >5° after brace cessation without progression to surgical magnitude (n = 15). There was no difference between progressors and nonprogressors in age or menarchal status at brace initiation or completion, nor was there a difference in curve magnitude or morphology at initiation. There was no difference in duration of or compliance with bracing. Patients with postbrace surgical progression completed bracing at 46° on average compared with 33° for those who did not progress to surgical magnitude (P < 0.0001). Patients who completed bracing at >45° had an incidence of postbrace surgical progression of 67%. No patients who completed bracing with curves <40° showed progression after brace cessation. Conclusions A total of 14.1% of patients successfully treated for AIS with bracing later progressed to surgical magnitude, and an additional 17.6% progressed >5° after brace completion. Findings suggest that patients with curves measuring >40° at brace completion should be followed into young adulthood. Counseling regarding the potential future need for surgery is warranted once a curve exceeds 45° in braced patients. Level of Evidence Level 2 prospective cohort study

ABSTRACT Introduction After amputation, altered sensory input leads to cortical reorganization that partly explains phantom limb pain (PLP). However, many factors impact the PLP phenomenon, and modern conceptualizations of chronic pain including PLP integrate both peripheral inputs and central interpretation. Clinicians without functional MRI could benefit from clinical measures related to PLP to assess clinical presentations. The purpose of this pilot study was to identify peripheral sensation and cognition measures related to PLP to inform outcome measure selection in future PLP research. Methods This cross-sectional analysis included people with PLP of any age, sex, and amputation cause or level. Assessments included patient-reported residual limb pain and PLP using the Prosthesis Evaluation Questionnaire, peripheral sensation measures (light touch, temperature, vibration, two-point discrimination), and cognition measures (laterality recognition, trail making, clock drawing). Unadjusted Spearman ρ coefficients were reported. Results Eleven volunteers (48.5 ± 13.2 years) with lower-limb amputations (seven transtibial) of various causes (nine medical) participated. More severe PLP symptoms were associated with impaired peripheral sensation (light touch, ρ = 0.514; temperature, ρ = 0.756) and poorer cognition (laterality recognition, ρ = 0.524; trail making, ρ = 0.565). Residual limb pain was not correlated with cognition measures (ρ < 0.4). Conclusions This pilot study identified clinical measures assessing cognition and peripheral sensation impairments associated with worse PLP symptoms. Phantom limb pain was related to temperature and light touch sensation measures, but two-point discrimination was not associated with PLP consistent with past research. Laterality recognition was associated with PLP per prior research, and the association of PLP with the Trail Making Test in this pilot study suggests that the Trail Making Test may be an additional cognition measure potentially useful in future clinical research to document the PLP experience.

Phantom limb pain was related to temperature and light touch sensation measures, but two-point discrimination was not associated with PLP consistent with past research. Laterality recognition was associated with PLP per prior research, and the association of PLP with the Trail Making Test in this pilot study suggests that the Trail Making Test may be an additional cognition measure potentially useful in future clinical research to document the PLP experience.","PeriodicalId":53702,"journal":{"name":"Journal of Prosthetics and Orthotics","volume":"34 1","pages":"89 - 94"},"PeriodicalIF":0.6,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45709837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Introduction This initial cost-effectiveness evaluation compared the provision of transtibial bone-anchored prostheses (TTA-BAPs) with socket-suspended prostheses (TTA-SSPs) over a 6-year time horizon from a governmental prosthetic care perspective. The purposes were to present ways we dealt with barriers encountered during the cost-effectiveness analysis. The objectives were to detail the extraction of baseline and incremental costs and utilities required to provide preliminary incremental cost-effectiveness ratios (ICERs) per quality-adjusted life-year (QALY). Materials and Methods This retrospective case-series study involved six participants fitted consecutively with TTA-SSP and TTA-BAP. Total costs combined actual and typical costs extracted from financial records and a schedule of allowable expenses, respectively. Baseline utilities were extracted from the literature, whereas incremental utilities were assumed. Results ICERs ranged between −$25,065 and $41,929 per QALY. Indicative ICER was approximately $11,400 per QALY. Provision of TTA-BAP was cost-effective and cost saving for 83% and 33% of cases, respectively. Discussion Educated choices were required to overcome unavailability of individual costs (e.g., creation of schedule of allowable expenses, blending of actual and typical costs) and utilities (e.g., extraction of baseline from literature, assumptions for incremental gain). Indicative ICER might lead to adoption of TTA-BAP, at least from an Australian governmental prosthetic care perspective.

ABSTRACT Introduction The risk of accidental falls is greater in people with lower-limb loss than in their able-bodied peers. Most popular strategies to mitigate injuries from such falls include technical solutions that prevent falls or protect vulnerable body segments from destructive forces. Fall training is another effective intervention, but little evidence on its use in prosthesis users has been published. This research had the goal to investigate to what extent fall training is provided to the target population and what factors may be obstacles to its wider adoption. Methods An online questionnaire was developed and administered nationwide, targeting people with lower-limb loss. Descriptive statistics were used to describe the availability of fall training, and a logistic regression was performed to investigate variables that predict whether an individual receives fall training or not. Results A total of 180 responses was recorded, 166 of which were included in the analysis. More than two-thirds of respondents had not received fall training. Those who had physical therapy as part of their rehabilitation regimen were 3.7 times more likely to also have had fall training. Discussion Our data suggest that the potential benefits of providing fall training to people with lower-limb loss are not being fully realized. Interdisciplinary collaboration between prosthetists and therapists can help expand access to fall training interventions to better prepare patients for the likely event of an accidental fall.

ABSTRACT Introduction After upper-limb amputation, employment opportunities may be limited. Given the dramatic shift in the job market in the United States in the recent years, there is a need to examine the updated employment rates and the types of occupations to which individuals with amputation can return to. In this study, we assessed current employment status for people with upper-limb loss and determined whether these individuals needed to change jobs as a result of limb loss. Second, we examined whether demographic or impairment-specific factors were correlated with employment status or the need to switch jobs. Materials and methods Individuals with upper-limb amputation provided personal and employment information in an online survey. We explored the bivariate relationships between employment status and 11 personal factors (e.g., age at amputation, highest education level). Using the significant factors from this analysis, we built a logistic regression model for postamputation employment status. We also explored the relationship between these same 11 factors and the individuals' need to switch jobs after limb loss. Results A total of 199 and 160 respondents were deemed eligible for the employment status and job switch analyses, respectively. Of the working-aged respondents, 60.8% (121/199) were employed at the time of survey. Twenty-nine percent (47/160) reported needing to change jobs because of their amputation. Factors negatively associated with employment included having a bilateral amputation, lower education level, older age at amputation, higher pain frequency, and wearing a prosthesis less frequently. Higher education level was the only significant predictor of successful employment in the logistic regression model. There were no significant relationships between any factor and the need to change jobs after amputation. Conclusions The results suggest that individuals with upper-limb amputation have a lower employment rate than the national average. Future work should focus on understanding the reasons behind employment challenges in this population.
