Prosthetics and Orthotics International最新文献

Background: It is obvious that educational activities were affected globally due to the pandemic.

Objective: This study was planned to examine the effects of online education on undergraduate degree (UD) and associate degree (AD) Orthotics and Prosthesis education in the COVID-19 pandemic.

Study design: A crossectional online survey.

Method: The Google Forms questionnaire was delivered to students of Orthotics and Prosthesis in the level of undergraduate degree and AD and academicians conducted in the study. Next, the participants were reviewed regarding their knowledge about devices used for online education and related technical problems. A 5-point Likert-type questionnaire with 18 questions that was developed specifically for this study was applied to examine their views on online education.

Results: The study included 472 participants who had a mean age of 21.30 ± 0.22 years. Among the participants, 262 were AD students (55.5%). Approximately 82% of the participants were used their mobile phones for connection. The connection problems, and inappropriateness of online education in applied course, preference of online education for theoretical courses, insufficiency of digital course materials, failure to access education easily, insufficiency of online examinations for measurement and evaluation, and preference of homework over online education were stated by 79%, 88.3%, 41.9%, 54.5%, 70.1%, 41.7%, and 42.8% of the participants, respectively.

Conclusion: Both academicians and students experienced connection problems, and applied courses were not suitable for online education. Motivation to attend the courses was low in online education, relevant workload increased, online examinations were not sufficient for measurement and evaluation, and studies were more unplanned. It is necessary to switch to formal education after the pandemic.

Background: Relative movement between the socket and residual limb can impair function in prosthesis users. It is plausible that, in addition to its mechanical effect, the integrity of the socket-residuum interface influences the ability of an individual to sense tactile cues through the prosthesis. Vacuum-assisted suspension (VAS) has been shown to reduce relative movement at this interface, providing a means to test this premise. The purpose of this pilot study was to assess the effects of altering socket-residuum interface integrity through the VAS pressure level on the thresholds of perception of an externally applied vibration stimulus.

Methods: Seven unilateral transtibial prosthesis users participated. Socket-residual limb integrity was altered using the VAS subatmospheric (vacuum) pressure level. Vibration perception tests were conducted at low, mid, and high vacuum levels, targeting 0, 8, and 19 in Hg respectively, and performed in partially loaded and fully loaded conditions. Vibration intensity was increased using a dial until participants delivered a verbal signal indicating it was perceptible, and the nominal intensity was recorded.

Results: Intensity thresholds decreased (ie, sensitivity increased) from low to high vacuum settings when fully loaded ( P = 0.008). Differences when partially loaded were nonsignificant and variable across participants.

Conclusion: This study provides preliminary evidence that altering the integrity between the socket and residual limb by modifying the vacuum level affects sensation related to the external environment experienced through the prosthesis, although translation of these findings to real-world stimuli remains to be tested.

Purpose: This study investigated the barriers, challenges, and facilitators in receiving prosthetic services in people with lower limb amputation during Covid-19 pandemic.

Materials and methods: In this qualitative study, we conducted in-depth semistructured face-to-face interviews with individuals with lower limb amputation who needed prosthetic services during Covid-19 pandemic. We discussed about challenges and barriers that the participants had encountered during this period. The collected data were analyzed using a conceptual framework.

Results: Six broad themes of availability, accessibility, acceptability, affordability, accommodation, and awareness emerged from the analysis. Staff shortage, lack of remote services, accommodation, insurance and governmental support, and cost of services were the main concerns. Moreover, long waiting lists, postponed referrals, noncompliance with Covid-19 protocols and preventive measures, and lockdowns were the other important concerns that were noted. In addition, unsatisfactory services in hometown, distance to capital, transportation permit in lockdowns, traffic jam, and public transport problems were other reasons of service not being accessible. The positive aspects were the facilitators such as having home visits, social work and charity, and using private drive services.

Conclusion: It seems that after the beginning of Covid-19 pandemic, people with lower limb amputation have faced more drastic challenges in accessing and receiving prosthetic services than in the prepandemic situations.

Background: Backward walk training has an important place in the rehabilitation programs of lower extremity amputees.

Objective: This study aimed to investigate the test-retest validity and reliability of the 3-meter backward walk test (3MBWT), minimal detectable change, and the cutoff time in high functional level adults with lower limb amputations (LLAs). Adults with LLA (n = 30) and healthy adults (n = 29) were included in the study.

Study design: This is a randomized cross-sectional study.

Methods: The Modified Fall Efficacy Score, Rivermead Mobility Index, and Timed Up and Go test with the 3MBWT were used to evaluate the concurrent validity of the test. The second evaluation (retest) was performed by the same physiotherapist 1 week following the first evaluation (test). The validity was assessed by correlating the 3MBWT times with the scores of other measures and by comparing the 3MBWT times between adults with LLA and healthy adults.

Results: Test-retest reliability of the 3MBWT was excellent. The intraclass correlation coefficient for the 3MBWT was 0.950. The standard error of measurement and minimal detectable change values were 0.38 and 0.53, respectively. A moderate correlation was found between the 3MBWT, Modified Fall Efficacy Score, Timed Up and Go test, and Rivermead Mobility Index ( p < 0.001). Significant differences in the 3MBWT times were found between adults with LLA and healthy controls ( p < 0.001). The cutoff time of 3.11 s discriminates healthy adults from high functional level adults with LLA.

Conclusions: The 3MBWT was determined to be valid, reliable, and easy-to-apply tool in high functional level adults with LLA. This assessment is a useful and practical measurement for dynamic balance in high functional level adults with LLA.

Purpose: The aim of this study was to describe the demographic and clinical characteristics of children with limb loss in Saudi Arabia.

Methods: This is a retrospective study on children attending a limb loss clinic in a tertiary hospital in Riyadh, Saudi Arabia, between July 2012 and June 2020. Descriptive statistics were computed to describe the sample characteristics. A Chi-Squared test was conducted to explore the relationship between a child's sex with the type of limb loss (congenital or acquired) and extent of limb loss (major and minor) and the association between child's age and the mechanism of injury in traumatic limb loss.

Results: A total of 122 children aged 2-16 years were included of whom 52% were boys. Congenital limb loss represented 57% of the sample with upper extremity loss accounting for 63.7% of all limb loss in this type. Trauma-related limb loss represented the most frequent etiology (88.2%) in the acquired limb loss group. Road traffic accidents accounted for 51.7% of the mechanism of injuries in trauma-related limb loss. Child's sex was not associated with the type of limb loss nor the extent of limb loss ( p > 0.05). In addition, child's age was not associated with the mechanism of injury in traumatic limb loss ( p > 0.05).

Conclusion: Child's sex was not a determinant of type nor the extent of limb loss. Most of the acquired limb loss was trauma-related with road traffic accidents as the most common mechanism of injury. The findings of this study illuminate the importance of ongoing prosthetic care for children with a limb loss because young children may require multiple prostheses as they grow in age and size.

Background objective: The purpose of this study was to evaluate prosthetic outcome in patients with severe congenital femoral deficiency and the potential benefits of surgical intervention on prosthetic fitting and gait.

Methods: A retrospective review identified 26 active case records with a proximal femoral focal deficiency using a prosthesis. Validated outcome measures evaluated comfort, function, and prosthetic use and quality-of-life assessment. Outcome compared age groups and surgical intervention. Gait analysis performed in 7 patients further evaluated hip and knee function.

Results: Eleven male patients and 15 female patients, including 13 children (mean age 10 years, range 5-16) and 13 adults (mean age 36 years, range 23-63) were evaluated. Better prosthetic function and PedsQL scores were recorded in the pediatric group. There was a trend for better scores after surgery. Gait analysis demonstrated reduced hip extension compensated by knee flexion in 3 patients, 2 patients had hip extension with near normal kinematics, 1 untreated patient walked with an unsteady gait, and the remaining walked well using an ischial-bearing prosthesis with pelvic compensatory movements.

Conclusion: The management strategy in severe proximal femoral focal deficiency remains a major challenge. Hip reconstruction seems to improve functional scores. Overall, the scores seem to decline into adulthood but not significantly. Gait analysis before further surgical intervention is recommended because compensatory knee flexion may improve step length in terminal stance. Limited numbers, with short follow-up, prevents clear guidance on the benefit of surgery.

Background: Orthotic devices are required for walking in many individuals with myelomeningocele. Evidence concerning orthosis use is sparse, partly because of heterogeneity among groups and different definitions of the neurological level.

Objectives: The objective of this study was to investigate ambulation regarding orthosis use and satisfaction with orthoses after intense orthotic management during childhood.

Study design: The study design is a retrospective follow-up with a cross-sectional study at adult age.

Methods: Participants comprised 59 persons born in 1985 or later. Ambulation was categorized as community (Ca), household (Ha), nonfunctional (N-f), and nonambulation (N-a) groups. Orthosis use was registered at approximately 5 (Age5) and 12 (Age12) years of age and in adulthood (AdultAge). Satisfaction with orthoses was evaluated at AdultAge.

Results: At Age5, Age12, and AdultAge, orthoses were used by 100%, 98%, and 78% of participants, respectively. Ambulation deteriorated between Age5 and Age12 in 17% of participants and between Age12 and AdultAge in 46%. At AdultAge, 63% maintained their ambulatory function; and muscle function and hip and knee flexion contractures were strongly correlated with ambulation. The ambulation groups did not differ regarding satisfaction with device or services, except in 2 single items where the Ha group differed in ratings from the N-f and N-a groups.

Conclusion: The high frequency of orthosis use and similar satisfaction in all ambulation groups emphasize that early planning and follow-up of orthosis treatment during growth are important for mobility in adulthood. Our results also underline the importance of a close assessment of each individual's condition.
