Modified Cephalic Index Measured at Superior Levels of the Cranium Revealed Improved Correction With Helmet Therapy for Patients With Sagittal Suture Craniosynostosis.

OBJECTIVE: Historically, studies have shown that cranial remolding therapy improves surgical correction and protects against regression for patients with sagittal suture craniosynostosis. This study aimed to define the most responsive cranial height for measuring cephalic index (CI) following cranial remolding therapy for infants with sagittal suture craniosynostosis. METHODS: The authors performed a retrospective analysis of data between January 2018 and August 2019. The outcomes measured were CI-3 (level of glabella) through CI-7 (superior to eurions), where each value was defined as the width at levels 3 through 7 divided by the length at level 3. Differences between baseline- and post-treatment measurements were assessed using a 5 × 2 repeated measures analysis of variance. RESULTS: Data from thirty-four patients (19 males, 15 females, and mean age 2.79 months) were analyzed. Mean treatment duration was 4.59 ±â€Š1.86 months. There was a significant increase between baseline and posttreatment measurements (baseline: 72.60% ±â€Š0.70%, post: 76.30% ±â€Š0.80%; F1,33 = 27.74, P < 0.001). The interaction effect for CI level ∗ baseline-post was also significant (F1.43,47.16 = 6.75, P = 0.006). Post hoc analyses revealed the posttreatment measures were significantly greater than baseline measures at every CI level. The magnitude of the measured differences systematically decreased from CI-7 to CI-3, with a greater effect size at the most superior level (ie CI-7) of 0.961 compared to 0.778 at the traditional level (ie CI-3). CONCLUSIONS: The CI measurement at level 7 demonstrated the greatest responsiveness to treatment, whereas the traditional CI measurement taken at level 3, the current standard, proved the least responsive.

Quantifying Orthotic Correction of Trigonocephaly Using Optical Surface Scanning.

ABSTRACT: Numerous publications describe techniques to measure trigonocephaly caused by metopic synostosis, but they are potentially hazardous for use in acquiring longitudinal data. Optical surface scanning technology can safely yield craniometrics but has not established a practical means for measuring objective morphological changes to trigonocephaly during the practical time constraints of a clinical visit. The purpose of this preliminary study was to evaluate a method for safely and repeatedly measuring frontal angle (FA) using technology available at multiple centers providing treatment with cranial remolding orthoses.Optical scans of infants who underwent endoscopic-assisted minimally-invasive craniectomy for repair of metopic synostosis with cranial remolding were retrospectively analyzed. A novel FA measurement technique "FA30" was developed based on repeatable, geometrically-related surface landmarks approximating the glabella and frontotemporali. Results were compared to a control group and categories of non-synostotic deformity. Inter-rater reliability was assessed for pre- and post-treatment scan measurements among separate clinicians.All trigonocephalic subjects (n = 5) had initial FA30 significantly lower than the control group and other cohorts (P < 0.001). During the course of orthotic cranial remolding following surgical release mean FA30 increased from 121.5° to 138.5° (P < 0.001), approaching the control group mean of 144.4°. Intraclass coefficient calculation showed high reliability (intraclass correlation coefficient: 0.993, 95% confidence interval: 0.957-0.998, P < 0.001), which was supported with Bland-Altman analyses of agreement.Optical surface scanning may provide a safe, accurate, and repeatable means to measure FA. Increase in FA30 demonstrates correction of trigonocephaly. The method presented enables expeditious reporting of treatment progress to the infant's surgeon and parents, and has potential for use in optimizing treatment outcomes at multiple centers.

Mobility Analysis of AmpuTees (MAAT 6): Mobility, Satisfaction, and Quality of Life among Long-Term Dysvascular/Diabetic Prosthesis Users-Results of a Cross-Sectional Analysis.

OBJECTIVE: The aim of this study was to establish the mobility, satisfaction, and quality of life (QoL) among prosthesis users with dysvascular/diabetic amputation at both acute and long-term phases of prosthetic rehabilitation. METHODS: This is a multisite, cross-sectional outcomes analysis. A total of 341 individuals met the inclusion/exclusion criteria. Individuals were grouped into acute phases (0-3 months [n = 24], 4-6 months [n = 72]) and chronic phases (24-36 months [n = 91], 37-48 months [n = 53], 49-60 months [n = 47], and 60-84 months [n = 54]) after amputation. Mobility was measured with the Prosthetic Limb Users Survey of Mobility (PLUS-M), whereas QoL and satisfaction (Sat) were reported using 10-point scales adapted from the Prosthesis Evaluation Questionnaire-Well-Being (PEQ-WB). Composite PEQ-WB scores were also compared. RESULTS: The average mobility, QoL, and Sat among prosthesis users was, respectively, 44.8 ± 10.6, 7.6 ± 2.2, and 7.6 ± 2.2. There were no observed differences in mobility (F 5,330 = 1.52, P = 0.18), QoL (F 5,333 = 0.78, P = 0.57), or PEQ-WB (F 5,335 = 1.618, P = 0.155) between any groups. For Sat, there was a group difference (F 5,334 = 2.44, P = 0.03) as individuals appear to experience an initial increase in Sat with receipt of a prosthesis (0-3 months) compared with 25 to 36 months (P = 0.005), 49 to 60 months (P = 0.008), and 61 to 84 months (P = 0.009). CONCLUSIONS: Those individuals with amputation secondary to dysvascular disease and diabetes who continue to participate in prosthetic rehabilitation appear to experience levels of mobility, Sat, and QoL 7 years after amputation comparable to that reported in the first 6 months postamputation. There may be a modest increase in Sat with receipt of an initial prosthesis, potentially due to an increased optimism for one's situation. Notably, the mobility levels observed in the dysvascular population through a range of long-term postamputation periods remain within a single standard deviation of the population mean for individuals with a lower-limb amputation using a prosthesis for mobility.

Prosthetic Knee Selection for Individuals with Unilateral Transfemoral Amputation: A Clinical Practice Guideline.

INTRODUCTION: This guideline was developed to present the evidence and provide clinical recommendations on prosthetic knee selection for unilateral amputation at the knee disarticulation or transfemoral level. METHODS: The guideline is based upon the best available evidence as it relates to prosthetic knee selection after unilateral knee disarticulation or transfemoral amputation. Recommendations are drawn from systematic review, meta-analysis, and additional published practice guidelines. RESULTS: Recommendation 1. Fluid knee benefits and indications: Knees with hydraulic or pneumatic swing resistance are indicated for active walkers, permitting increased walking comfort, speed, and symmetry.Recommendation 2. Microprocessor knee benefits: Compared with nonmicroprocessor knees:a) With respect to self-report indices and measures, microprocessor knees are indicated to reduce stumbles, falls, and associated frustrations as well as the cognitive demands of ambulation.b) With respect to self-report indices and measures, microprocessor knees are indicated to increase confidence while walking, self-reported mobility, satisfaction, well-being, and quality of life.c) With respect to physical performance indices and measures, microprocessor knees are indicated to increase self-selected walking speed, walking speed on uneven terrain, and metabolic efficiency during gait.Recommendation 3. Microprocessor knee equivalence: Given the comparable values observed with the use of microprocessor and nonmicroprocessor knees with regard to daily step counts, temporal and spatial gait symmetry, self-reported general health, and total costs of prosthetic rehabilitation, these parameters may not be primary indications in prosthetic knee joint selection.Recommendation 4. Microprocessor knees for limited community ambulators: Among limited community ambulators, microprocessor knees are indicated to enable increases in level ground walking speed and walking speed on uneven terrain while substantially reducing uncontrolled falls and increasing both measured and perceived balance. CONCLUSIONS: These clinical practice guidelines summarize the available evidence related to prosthetic knee selection for individuals with unilateral knee disarticulation or transfemoral amputation. The noted clinical practice guidelines are meant to serve on as "guides." They may not apply to all patients and clinical situations.

The role of exercise testing in predicting successful ambulation with a lower extremity prosthesis: a systematic literature review and clinical practice guideline.

BACKGROUND: Growing discontent with the k-level system for functional classification of patients with limb loss and movement of healthcare toward evidence-based practice has resulted in the need for alternative forms of functional classification and development of clinical practice guidelines to improve access to quality prosthetic interventions. The purpose of this project was to develop and present a clinical practice recommendation for exercise testing in prosthetic patient care based on the results and synthesis of a systematic literature review. METHODS: Database searches of PubMed, Google Scholar, Web of Science, and Cochrane were conducted and articles reviewed. Of the potential 1386 articles 10 met the criteria for inclusion. These articles were assessed using the critical appraisal tool of the United Kingdom National Service Framework for Long-Term Conditions. Of the 10 included articles eight were of high, one of medium, and one of low, quality. Data from these articles were synthesized into 6 empirical evidence statements, all qualifying for research grade A. These statements were used to develop the proposed clinical practice guideline. RESULTS: While the results of this systematic review were not able to support the direct connection between cardiorespiratory performance and K-levels, the literature did support the ability of exercise testing results to predict successful prosthetic ambulation in some demographics. Both continuous maximum-intensity single lower extremity ergometer propelled by a sound limb and intermittent submaximal upper extremity ergometer protocols were found to be viable evaluation tools of cardiorespiratory fitness and function in the target population. CONCLUSION: The ability to sustain an exercise intensity of ≥50% of a predicted VO2max value in single leg cycle ergometry testing and achievement of a sustained workload of 30 W in upper extremity ergometry testing were found to be the strongest correlates to successful ambulation with a prosthesis. VO2 values were found to increase in amputee subjects following a 6-week exercise program. These synthesized results of the systematic literature review regarding exercise testing in patients with loss of a lower extremity were used to develop and a present a clinical treatment pathway.

Prosthetic Foot Selection for Individuals with Lower-Limb Amputation: A Clinical Practice Guideline.

INTRODUCTION: This guideline was developed to present current evidence and to provide associated clinical recommendations on prosthetic foot selection for individuals with lower-limb amputation. MATERIALS: NA. METHODS: The guideline is based upon the best available evidence as it relates prosthetic foot selection during the provision of definitive lower-limb prostheses. Where possible, recommendations are drawn from Cochrane Review, meta-analysis, systematic and narrative literature reviews, and published evidence-based guidelines. Where this standard is unavailable, alternate academic literature has been used to support individual recommendations. RESULTS: Recommendation 1: For patients ambulating at a single speed who require greater stability during weight acceptance because of weak knee extensors or poor balance, a single-axis foot should be considered. Recommendation 2: Patients at elevated risks for overuse injury (i.e., osteoarthritis) to the sound-side lower limb and lower back are indicated for an energy-storage-and-return (ESAR) foot to reduce the magnitude of the cyclical vertical impacts experienced during weight acceptance. Recommendation 3: Neither patient age nor amputation etiology should be viewed as primary considerations in prosthetic foot type. Recommendation 4: Patients capable of variable speed and/or community ambulation are indicated for ESAR feet. CONCLUSIONS: These clinical practice guidelines summarize the available evidence related to prosthetic foot selection for individuals with lower limb amputation. The noted clinical practice guidelines are meant to serve only as "guides." They may not apply to all patients and clinical situations.

Orthotic Management of Deformational Plagiocephaly: Consensus Clinical Standards of Care.

OBJECTIVE: To establish consensus on definitive, actionable standards for the management of deformational plagiocephaly. DESIGN: Three-stage Delphi Survey process based on best practice statements obtained through literature review. SETTING: Electronic survey delivery. PARTICIPANTS: Review panel of 10 multidisciplinary subject matter experts (SMEs); survey panel of 30 cranial orthotists. RESULTS: Fifty-four best practice statements were accepted in four categories: diagnosis, presentation and severity, initiating treatment, and management principles. CONCLUSIONS: Clinical practice can be guided en route to robust evidence as to the efficacy of various plagiocephaly management strategies, in pursuit of definitive standards.

Utilization of orthoses and assistive devices among a national sample of lower limb orthosis users.

Introduction: Lower limb orthoses (LLOs) and assistive devices (ADs) can be used together or separately to improve mobility when performing daily activities. The goal of this study was to examine utilization of LLOs and ADs in a national sample of adult LLO users. Methods: A survey was designed to ask participants whether they typically use their LLOs and/or ADs to perform 20 daily activities. LLO users from orthotic clinics across the United States were invited to complete the survey. Descriptive statistics were used to examine utilization trends. Results: Survey responses from 1036 LLO users were analyzed. Community-based activities were performed with LLOs by at least 80% of participants. Activities that involved walking short distances in the home were more often performed without LLOs or ADs. Among participants with the four most prevalent health conditions, LLO use in the community was greatest among participants with Charcot-Marie-Tooth disease. Conclusions: LLOs were frequently used for a wide range of community-based activities. Simultaneous use of ADs and LLOs may be most beneficial for LLO users when performing activities outside of the home. Clinicians can discuss LLO and AD use with patients to optimize their functional outcomes at home and in the community.

Functional and perceptive differences between conventional and advanced ankle foot orthoses in community ambulators post-limb trauma: the injuries managed with advanced bracing of the lower extremity (IM ABLE) study.

Introduction: Many military service members and civilians suffer from lower extremity trauma. Despite recent advancements in lower limb bracing technology, it remains unclear whether these newer advanced braces offer improved comfort and functionality compared to conventional options. The IDEO (Intrepid Dynamic Exoskeletal Orthosis), a type of "advanced" orthosis was developed to assist in maintaining high functional performance in patients who have experienced high-energy lower extremity trauma and underwent limb salvage surgeries. Methods: A cross-sector multi-site initiative was completed to study the efficacy of advanced ankle foot orthoses (AFO) for lower limb trauma and injury compared to a conventional AFO. Following fitting, training, and accommodation, the subjects were assessed in each AFO system for mobility, self-reported function, safety and pain, and preference. Results: They preferred the advanced over the conventional AFO and the mobility and exertion perception improved with the advanced AFO with no difference in pain or overall health status scores. Discussion: Thus, an advanced AFO is an option for trauma affecting the lower limb. Long-term studies are required to better understand the accommodation and learning process of using an advanced AFO.

Stability and Falls Evaluations in AMPutees (SAFE-AMP 1): Microprocessor knee technology reduces odds of incurring an injurious fall for individuals with diabetic/dysvascular amputation.

Individuals with lower limb amputation have a high incidence of falls. Above-the-knee amputation and diabetes/vascular disease are both risk factors for falls. Microprocessor knee (MPK) technology may reduce falls in this population. The objective was to determine the association between MPKs and reduced injurious falls. A retrospective analysis of injurious falls within a large, national outcomes database was conducted. Inclusion was limited to adult K3 ambulators with unilateral, transfemoral, or knee disarticulation amputation due to diabetes/vascular disease. There were 744 out of 881 individuals that did not receive an MPK. Results showed that 16.3% of non-MPK users experienced an injurious fall compared to 7.3% of MPK users (p = .007). Not having an MPK resulted in significantly increased odds (unadjusted: OR: 2.47, 95% CI: 1.26-4.83, p = .009; adjusted for confounders: OR: 2.52, 95% CI: 1.28-4.94, p = .007) of incurring an injurious fall over a 6-month period. In conclusion, the current study found use of an MPK strongly associated with reduced injurious falls in a population of patients with amputation due to diabetes/vascular disease. The findings strongly support the use of MPK technology to mitigate fall risk, and in particular injurious falls requiring medical intervention.

Transfemoral interface considerations: A clinical consensus practice guideline.

BACKGROUND: Although there have been a number of studies exploring the impact and efficacy of transfemoral prosthetic components such as knee and foot mechanisms, the empirical evidence surrounding transfemoral prosthetic interface considerations is limited. This constitutes a substantial void for practicing clinicians seeking to apply best practices for patients who use transfemoral prostheses. Recent years have seen increased production and availability of clinical practice guidelines germane to prosthetic rehabilitation. In those areas where empirical evidence is lacking, consensus clinical opinions may constitute the highest level of evidence. OBJECTIVE: A consensus exercise was performed to generate clinical practice recommendations in the areas of transfemoral interface considerations including socket variations and critical design features, suspension and interface considerations, alignment, heat retention and dermatologic considerations, female considerations, surgical considerations, and both regulatory and ethical considerations related to osseointegration. METHODS: This began with the generation of postulate items through systematic and narrative literature reviews. A Delphi consensus exercise was performed among clinical experts in government hospital and private clinical practice settings, culminating in a series of clinical practice recommendations associated with the prosthesis-limb interface for individuals with transfemoral amputation. RESULTS: The completed recommendations include guidance statements relative to socket variations and critical design features, female considerations, suspension and interface considerations, surgical variations and prescription considerations, rehabilitation team considerations and both regulatory and ethical considerations related to osseointegration. CONCLUSIONS: The Delphi process facilitated the development of practice guidelines for transfemoral prosthetic interface considerations based on aggregated subject matter expertise.

Activity and Participation, Bimanual Function, and Prosthesis Satisfaction are Strong Predictors of General Well-Being Among Upper Limb Prosthesis Users.

Objective: To determine the role of multiple factors on general well-being for upper limb prosthesis users. Design: Retrospective cross-sectional observational design. Setting: Prosthetic clinics across the United States. Participants: At the time of analysis, the database consisted of 250 patients with unilateral upper limb amputation seen between July 2016 and July 2021. Intervention: Not applicable. Main Outcomes Measures: Dependent variable: well-being (Prosthesis Evaluation Questionnaire- Well-Being). Independent variables included in analysis: activity and participation (Patient Reported Outcomes Measurement Information System [PROMIS] Ability to Participate in Social Roles and Activities), bimanual function (PROMIS-9 UE), prosthesis satisfaction (Trinity Amputation and Prosthesis Experience Scales-Revised; TAPES-R), PROMIS pain interference, age, gender, average daily hours worn, time since amputation, and amputation level. Results: A multivariate linear regression model using a forward enter method was applied. The model included 1 dependent variable (well-being) and 9 independent variables. Within the multiple linear regression model, the strongest predictors of well-being were activity and participation (ß=0.303, P<.0001), followed by prosthesis satisfaction (ß=0.257, P<.0001), pain interference (ß=-0.187, P=.001), and bimanual function (ß=0.182, P=.004). Age (ß=-0.036, P=.458), gender (ß=-0.051, P=.295), time since amputation (ß=0.031, P=.530), amputation level (ß=0.042, P=.385), and hours worn (ß=-0.025, P=.632) were not significant predictors of well-being. Conclusion: Reducing pain interference and improving clinical factors such as prosthesis satisfaction and bimanual function with their associated effects on activity and participation will positively affect the well-being of individuals living with upper limb amputation/congenital deficiency.

Assessment of Patient-Reported Physical Function in Persons With Upper Extremity Amputation: Comparison of Short Form Instruments.

OBJECTIVE: The aim of the study was to compare psychometric properties of the Patient-Reported Outcomes Measurement Information System upper extremity measure (PROMIS UE) 7-item short form with 6- and 13-item versions for persons with upper limb amputation. DESIGN: The study used a telephone survey of 681 persons with upper limb amputation. Versions were scored two ways: PROMIS health measure scoring (PROMIS UE HMSS) and sample-specific calibration (PROMIS UE AMP). Factor analyses and Rasch analyses evaluated unidimensionality, monotonicity, item fit, differential item functioning, and reliability. Known group validity was compared for all versions. RESULTS: Model fit was acceptable for PROMIS-6 UE AMP and marginally acceptable for PROMIS-13 UE AMP and PROMIS-7 UE AMP. Item response categories were collapsed because of disordered categories. A total of 91.4% of participants had PROMIS-13 UE AMP scores with reliability greater than 0.8, compared with 70.4% for PROMIS-7 UE AMP, and 72.1% for PROMIS-6 UE AMP versions. No differences were observed by prosthesis use. Scores differed by amputation for all measures except the HMSS scored 13- and 7-item versions. CONCLUSIONS: The PROMIS-13 UE AMP short form was superior to the health measures scoring system scored PROMIS-7 UE or PROMIS-6 UE, and to the PROMIS-7 UE AMP and PROMIS-6 UE AMP. Issues with known group validation suggest a need for a population-specific measure of upper extremity function for persons with upper limb amputation.

Creating Adjusted Scores Targeting mobiLity Empowerment (CASTLE 1): determination of normative mobility scores after lower limb amputation for each year of adulthood.

PURPOSE: As United States healthcare transitions from traditional fee-for-service models to value-based care, there is increased need to demonstrate quality care through clinical outcomes. Therefore, the purpose of this study was to create equations to calculate an expected mobility score for lower limb prosthesis users specific to their age, etiology, and amputation level to provide benchmarks to qualify good outcomes. MATERIALS AND METHODS: A retrospective cross-sectional analysis of outcomes collected during clinical care was performed. Individuals were grouped based on amputation level (unilateral above-knee (AKA) or below-knee (BKA)) and etiology (trauma or diabetes/dysvascular (DV)). The mean mobility score (PLUS-M® T-score) for each year of age was calculated. AKAs were further stratified into having a microprocessor knee (MPK) or non-microprocessor (nMPK) for secondary analysis. RESULTS: As expected, average prosthetic mobility declined with age. Overall, BKAs had higher PLUS-M T-scores compared to AKAs and trauma etiologies had higher scores compared to DV. For AKAs, those with a MPK had higher T-scores compared to those with a nMPK. CONCLUSIONS: Results from this study provide average mobility for adult patients across every year of life. This can be leveraged to create a mobility adjustment factor to qualify good outcomes in lower limb prosthetic care.IMPLICATIONS FOR REHABILITATIONNormative values of mobility are needed to qualify good outcomes in prosthetic care as healthcare shifts towards value-based care.Understanding where an individual is relative to others with similar characteristics (e.g., age, etiology, gender, amputation level, and device type) can provide clinicians with better benchmarks for individual goal-setting.The ability to generate predicted mobility scores specific to each individual can create a mobility adjustment factor to better qualify good outcomes.

GGEM: Gender, Geography, and EMployment differences based on mobility levels among lower limb prosthesis users living in the United States.

BACKGROUND: For individuals with a disability, an increase in functional mobility may improve their quality of life and well-being. Greater understanding is needed on how factors such as gender, geography, and employment may play a role in mobility levels among individuals with lower limb amputation. OBJECTIVES: To assess the relationship between gender, geography, and employment status on mobility among lower limb prosthesis users. METHODS: A cross-sectional analysis of 7,524 patient mobility outcomes completed across the United States was performed. The regression model included the independent variables, such as age, gender, region, employment status, and amputation level. Mobility was entered as the dependent variable. RESULTS: Individuals who were employed had 3.6 times the odds of reaching increased mobility (Prosthetic Limb Users' Survey of Mobility ≥ 50) than those unemployed (odds ratio 3.56, 95% confidence interval 3.10-4.09). Gender and geography were significantly associated with mobility as well. CONCLUSIONS: Being employed is associated with greater odds of reaching increased mobility. Addressing factors such as returning to employment may aid in improving mobility levels among prosthesis users.

Development and initial validation of the Orthotic Patient-Reported Outcomes-Mobility (OPRO-M): An item bank for evaluating mobility of people who use lower-limb orthoses.

Lower limb orthoses (LLOs) are externally-applied leg braces that are designed to improve or maintain mobility in people with a variety of health conditions that affect lower limb function. Clinicians and researchers are therefore often motivated to measure LLO users' mobility to select or assess the effectiveness of these devices. Patient-reported outcome measures (PROMs) can provide insights into important aspects of a LLO user's mobility for these purposes. However, few PROMs are available to measure mobility of LLO users. Those few that exist have issues that may limit their clinical or scientific utility. The objective of this study was to create a population-specific item bank for measuring mobility of LLO users. Previously-developed candidate items were administered in a cross-sectional study to a large national sample of LLO users. Responses from study participants (n = 1036) were calibrated to a graded response statistical model using Item Response Theory methods. A set of 39 items was found to be unidimensional, locally independent, and function without bias due to characteristics unrelated to mobility. The set of final calibrated items, termed the Orthotic Patient-Reported Outcomes-Mobility (OPRO-M) item bank, was evaluated for initial evidence of convergent, divergent, and known groups construct validity. OPRO-M was strongly correlated with existing PROMs designed to measure aspects of physical function. Conversely, OPRO-M was weakly correlated with PROMs that measured unrelated constructs, like sleep disturbance and depression. OPRO-M also showed an ability to differentiate groups with expected mobility differences. Two fixed-length short forms were created from the OPRO-M item bank. Items on the short forms were selected based on statistical and clinical criteria. Collectively, results from this study indicate that OPRO-M can effectively measure mobility of LLO users, and OPRO-M short forms can now be recommended for use in routine clinical practice and research studies.

Clinical outcome measures to evaluate the effects of orthotic management post-stroke: a systematic review.

PURPOSE: To identify, and classify, according to International Classification of Functioning, Disability and Health (ICF), clinically applicable outcome measures that have been used to evaluate lower limb orthotic management post-stroke and to investigate which outcome measures recorded the largest effect sizes. MATERIALS AND METHODS: Electronic searches were performed in Pubmed, Cochrane, Web of Science, Cinahl, Scopus and Embase databases from inception to May 2020. Articles were included if they investigated clinical outcomes in people post-stroke who had received a lower-limb orthotic intervention. RESULTS: 88 articles underwent full-text review and 54 were included in the review, which was performed in accordance with the Preferred Reporting Items for Systematic Review (PRISMA) principles. 48 different outcome measures were identified; effect sizes were able to be calculated from 39 studies. The most frequently applied outcome measures were the 10-metre Walk Test and the timed-up-and-go test. Outcome measures that recorded large effect sizes in two or more studies were the 10-metre Walk Test, Functional Reach Test, and Physiological Cost Index. When coded according to the ICF, the most frequently represented codes were d450 (Walking) and d455 (moving around). CONCLUSIONS: Results suggest that outcome measures related to mobility (ICF chapter d4) are most often applied to evaluate orthotic management post-stroke. Effect sizes appear to be greatest in outcome measures related to velocity, balance, and energy expenditure.IMPLICATIONS FOR REHABILITATIONThe 10-meter Walk Test appears to have the greatest effect size when evaluating orthotic management post-stroke.While outcome measures related to mobility are commonly applied when evaluating orthotic management post-stroke, rehabilitation professionals should consider complementing these with measures representing the participation domain of the ICF.

Microprocessor feet improve prosthetic mobility and physical function relative to non-microprocessor feet.

Introduction: The clinical benefits associated with the microprocessor regulation of prosthetic ankle position and resistance have largely been reported through manufacturer conducted research in controlled laboratory environments. Measures with greater ecological validity are needed. This study aimed to understand if there are differences in physical function and mobility outcomes as patients transitioned from a non-Microprocessor to Microprocessor Feet. Method: A retrospective analysis of patient outcomes was performed. Patient-reported benefits associated with the adoption of such prosthetic foot-ankle mechanisms were collected from 23 individuals through the longitudinal use of a custom short form of the Patient-Reported Outcomes Measurement Information System-Physical Function and individual items from the Prosthesis Evaluation Questionnaire. Results: The impact of Microprocessor Feet upon physical function and mobility were observed in a significant increase in physical function (mean increase in t-score of 5.4 ± 1.25; p = .0004) and significant improvements in several mobility items. Conclusions: Collectively, these measures support the beneficial impact of Microprocessor Feet on improving socket comfort, reducing back pain, improving sit to stand transfers and enhancing hill ascent and descent as well as stair negotiation.

OASIS 2: Mobility differences with specific prosthetic feet across procedure codes.

Introduction: Recently, many prosthetic devices were subjected to reimbursement coding review. Several prosthetic feet that were historically coded with the shock-attenuating function were recoded. The purpose of this analysis was to compare patient-reported functional mobility across a range of prosthetic feet using real-world clinical outcomes data. Methods: A retrospective, observational review. A univariate generalized linear model was used to assess mobility across foot categories and between different prosthetic feet coded as L5987 or L5981. Results: The final sample analyzed comprised of 526 individuals and four mutually exclusive categories of feet examined across a total of 10 different prosthetic foot types. The comparison of prosthetic foot categories were significantly different from the control category (i.e. historically L5981). Conclusions: The current data suggest the development of some prosthetic foot designs using advanced materials and geometric designs can provide comparable functional benefits as those with distinct shock absorbing mechanical features. Emphasizing functional performance over visible features may be a pathway towards higher performance for the end user.
