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.

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.","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}

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).

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.

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.","PeriodicalId":53702,"journal":{"name":"Journal of Prosthetics and Orthotics","volume":"34 1","pages":"79 - 88"},"PeriodicalIF":0.6,"publicationDate":"2021-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43737839","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}

However, the potential benefits of these devices have not been evaluated among patients classified as household or limited community ambulators. This study examined the benefit of hydraulic- and microprocessor-controlled prosthetic ankles for patients classified as limited community ambulators. Materials and Methods Four different treatment configurations were evaluated using a randomized crossover study design. These four configurations included the participant's current flexible keel (FK) prosthetic foot, an energy-storage-and-return foot (ESAR), a hydraulic ankle (HA), and a microprocessor ankle (MPA). After a 2-week accommodation period, both patient-reported and performance-based outcome measures were recorded for each ankle foot system. A StepWatch activity monitor and two-dimensional video motion analysis were also used to evaluate each system. Results A single participant meeting the inclusion criteria was recruited. The patient-reported mobility and socket fit instruments were greatest with the HA system. When assessed on slopes and stairs, the MPA demonstrated benefits on hill ascent and stair descent. In considering the walking speed and perceived exertion jointly, the HA system allowed similar walking speed but lower exertion compared with fixed-ankle systems. The patient-reported low back pain and balance confidence instruments did not provide useful data for interpretation. Two-dimensional video motion analysis showed that the HA and MPA contributed to improved ankle and knee postures when ascending and descending a slope. The step activity data showed the greatest activity with the HA. Discussion The results from the outcome measures showed a varying level of benefit across all four of the treatment configurations. Both the HA and MPA had favorable scores in varying performance-based outcome measures, but the HA scored the most favorable in a majority of the patient-reported outcome measures. Conclusion The results show varying benefits of the microprocessor- and hydraulic-controlled prosthetic components over fixed-ankle ESAR and FK feet, based on both performance-based and patient-reported outcome measures.
