A qualitative study of clinicians' and individuals' with lower limb loss perspectives on the development of a novel online self-management program.

PURPOSE: To explore the rehabilitation preferences and experiences of clinicians and patients for education after lower limb loss to facilitate the development of an online self-management program. METHODS: A qualitative descriptive approach was used. Thirty-one clinicians (physiotherapists, occupational therapists, and prosthetists), and 26 patients with lower limb loss (transtibial and transfemoral amputation; mean age (SD) of 63.3 (9.1), years) were recruited. We used semi-structured focus groups and one-on-one interviews, and audio recorded the interviews. Data were analyzed using conventional content analysis. RESULTS: Three themes were identified: (1) Needing education in rehabilitation described the education in current practice as one-on-one discussion and booklets and highlighted the limitations of education such as its length, static nature, and inaccessible for patients living in remote areas. (2) Getting back to activities prior to amputation emphasized how goal setting and social support could assist patients and facilitate self-management. (3) Augmenting learning highlighted the need for an accessible complementary source for education and potential solutions to overcome the barriers of online delivery. CONCLUSIONS: Our findings underscore the importance of education in the rehabilitation of patients to help them get back to their activities. An online accessible tool may improve education by providing information and peer support.

Self-management education assists patients through knowledge and skills to adapt to an amputation.Education should be patient centred.An accessible user-friendly online tool which offers the information and peer support may augment and improve the delivery of self-management education.

Development of a co-created online self-management program for people with lower limb loss: self-management for amputee rehabilitation using technology (SMART).

PURPOSE: To develop an online self-management program for individuals with recent lower limb loss, called Self-Management for Amputee Rehabilitation using Technology (SMART). MATERIALS AND METHODS: We used the Intervention Mapping Framework as a blueprint and involved stakeholders throughout the process. A six-step study was conducted including (1) needs assessment using interviews, (2) translating needs to content, (3) applying the content into a prototype using theory-based methods, (4) a usability assessment using think-aloud cognitive testing, (5) planning for future adoption and implementation, and (6) assessing feasibility using mixed-methods to generate a plan to assess the effectiveness on health-outcomes in a randomized controlled trial. RESULTS: Following interviews with healthcare professionals (n = 31) and people with lower limb loss (n = 26), we determined the content of a prototype version. We then tested usability (n = 9) and feasibility (n = 12) by recruiting individuals with lower limb loss from different pools. We modified SMART to be assessed in a randomized controlled trial. SMART is a six-week online program with weekly contact of a peer mentor with lower limb loss who supported patients with goal-setting and action-planning. CONCLUSIONS: Intervention mapping facilitated the systematic development of SMART. SMART may improve health outcomes, but this would need to be confirmed in future studies.Implications for rehabilitationLearning new coping strategies and habits are essential after lower limb loss.Given the limitations and inaccessibility of educational and rehabilitation programs, online self-management education can assist patients in their recovery.Self-Management for Amputee Rehabilitation using Technology (SMART) has the potential to augment the self-management behaviors in individuals with lower limb loss through an improvement in access to educational content, skill-based videos, and support of a peer.

Social Prescribing Outcomes for Trials (SPOT): Protocol for a modified Delphi study on core outcomes.

PURPOSE: This is a study protocol to co-create with knowledge users a core outcome set focused on middle-aged and older adults (40 years+) for use in social prescribing research. METHODS: We will follow the Core Outcome Measures in Effectiveness Trials (COMET) guide and use modified Delphi methods, including collating outcomes reported in social prescribing publications, online surveys, and discussion with our team to finalize the core outcome set. We intentionally center this work on people who deliver and receive social prescribing and include methods to evaluate collaboration. Our three-part process includes: (1) identifying published systematic reviews on social prescribing for adults to extract reported outcomes; and (2) up to three rounds of online surveys to rate the importance of outcomes for social prescribing. For this part, we will invite people (n = 240) who represent the population experienced in social prescribing, including researchers, members of social prescribing organizations, and people who receive social prescribing and their caregivers. Finally, we will (3) convene a virtual team meeting to discuss and rank the findings and finalize the core outcome set and our knowledge mobilization plan. CONCLUSION: To our knowledge, this is the first study designed to use a modified Delphi method to co-create core outcomes for social prescribing. Development of a core outcome set contributes to improved knowledge synthesis via consistency in measures and terminology. We aim to develop guidance for future research, and specifically on the use of core outcomes for social prescribing at the person/patient, provider, program, and societal-level.

Usability of Self-Management for Amputee Rehabilitation using Technology (SMART): An online self-management program for users with lower limb loss.

BACKGROUND: Individuals with lower limb loss (LLL) need education to adapt to their amputation. Self-management programs provide education and supportive skills to manage health-related physical and psychological challenges. eHealth technologies, such as online platforms, are increasing access to educational resources. We designed an online self-management program for individuals with LLL called Self-Management for Amputee Rehabilitation using Technology (SMART); however, before evaluating its efficacy, we wanted to understand its appropriateness in the target population. OBJECTIVE: To assess the usability of SMART among individuals with LLL. STUDY DESIGN: The study used a concurrent and retrospective think-aloud process. METHODS: Individuals with LLL, aged 18 years or older (n = 9), reviewed the modules during an online video conferencing session with an assessor. SMART included four stakeholder-informed modules with 18 total sections. Participants were asked to think aloud while completing 11 SMART tasks, such as entering SMART, goal setting, finding skin care, and reading the content of 10 sections, including limb care, diet, fatigue, and energy. The interviews were transcribed verbatim and analyzed using directed content analysis. RESULTS: The median age was 58 (range: 30-69) years. Overall, SMART was perceived as straightforward, easy to navigate, and an accessible resource for education and skills. Difficulties were identified with navigation (e.g. skipping the "Foot care for diabetes" section), presentation (e.g. unclear audio), and language (e.g. pistoning and contracture). CONCLUSIONS: SMART was redesigned to address the usability issues. The next step is to explore the perceived usefulness of SMART for content and intention to use.

Protocol for a randomized controlled trial to assess the effect of Self-Management for Amputee Rehabilitation using Technology (SMART): An online self-management program for individuals with lower limb loss.

BACKGROUND: Lower limb loss (LLL) is a distressing experience with psychological, physical, and social challenges. Education is needed to enhance the coping skills and confidence of patients to improve LLL outcomes. However, access to rehabilitation services and education is limited outside of urban centers. To address this service gap, we co-created an eHealth platform, called Self-Management for Amputee Rehabilitation using Technology (SMART). OBJECTIVES: First, we will test the effect of SMART and usual care compared with usual care only on walking capacity and confidence among individuals with LLL. Second, we will describe key implementation factors for program delivery and adoption at the person- and provider-level. METHODS: This is a Type 1 Effectiveness-Implementation Hybrid Design, mixed-methods, multi-site (British Columbia and Ontario, Canada), parallel, assessor-blinded randomized controlled trial. Participants will include adults with unilateral LLL, during early prosthetic fitting (<2 years after casting for initial prosthesis). Participants in both groups will receive usual care. The experimental group will receive SMART with weekly support sessions from a trained peer mentor for goal setting and action planning for six weeks. Participants will be encouraged to continue using SMART for an additional four weeks. The control group will receive usual care, and weekly social contacts for six weeks. The primary outcome measure is walking capacity operationalized as the performance based Timed Up and Go test. The secondary outcome is walking confidence using the Ambulatory Self-Confidence Questionnaire. Outcome measures will be assessed at baseline, immediately post-intervention, and four weeks follow-up. We will describe key implementation factors (such as, participant experience, intervention adoption, fidelity) throughout the study using questionnaires, semi-structured interviews, and direct observation. RESULTS: No participants have been enrolled. CONCLUSIONS: SMART has the potential to provide knowledge and skill development to augment rehabilitation outcomes for adults with LLL. TRIAL REGISTRATION: NCT04953364 in Clinical Trial Registry (https://clinicaltrials.gov/).

Telehealth interventions for mobility after lower limb loss: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Mobility is a crucial component for healthy aging after lower limb loss (LLL). Telehealth technologies, for example, smart devices, are novel approaches for health programs delivery regardless of geographical boundaries. OBJECTIVES: To assess the effect of telehealth interventions on mobility, quality of life, and antecedents of health behavior compared with a control condition (usual care or simpler telehealth interventions with fewer number of behavior change techniques [BCTs]) for community-dwelling adults (>50 years) with an LLL and the effect of mode of delivery and BCTs used in telehealth interventions on health outcomes. STUDY DESIGN: Systematic review and meta-analysis. METHODS: We systematically searched MEDLINE, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane, PsycINFO, and SPORTDiscus on January 28, 2021, to identify relevant randomized controlled trials. Two authors independently screened records and assessed risk of bias. We conducted a narrative synthesis of evidence and, when appropriate, used the standardized mean difference (SMD) and mean difference for meta-analyses and the Grading Recommendations Assessment, Development, and Evaluation approach for practice recommendations. RESULTS: We identified six randomized controlled trials. Telephone was the most common delivery mode (n = 3), and "instructions for performing behaviors" was the most common BCT (n = 5). Very low certainty evidence showed no changes in mobility (six studies: SMD = 0.33 [95% confidence interval [CI] = -0.08, 0.75]), quality of life (two studies: mean difference = -0.08 [95% CI = -0.30, 0.15]), and antecedents of behavior (five studies: SMD = 0.04 [95% CI = -0.28, 0.36]). CONCLUSIONS: Our review highlights a knowledge gap for the effect of telehealth interventions for people with LLL. Although no promising effect was shown for telehealth interventions, very low certainty evidence precludes making a definitive clinical recommendation.

The Italian Spine Youth Quality of Life questionnaire: reliability and validity of the Persian version in adolescents with spinal deformities.

PURPOSE: To assess the reliability and validity of the Persian version of the Italian Spine Youth Quality of Life (P-ISYQOL) questionnaire. METHODS: Forward/backward translations and cultural adaption processes of the ISYQOL questionnaire into Persian were conducted by an expert committee. We recruited 178 adolescents with idiopathic scoliosis (AIS) and Scheuermann's kyphosis (SK) and 103 age-matched adolescents with no spinal deformity. Reliability was assessed by evaluating internal consistency and test-retest reliability using Cronbach's alpha and intraclass correlation coefficient (ICC). Convergent construct validity was assessed by measuring the association between the ISYQOL and revised 22-item Scoliosis Research Society (SRS-22r) questionnaires scores. Known-groups construct validity was assessed regarding curve magnitude, deformity, age, sex, and treatment type. RESULTS: Cronbach's alpha and ICC for P-ISYQOL total score was 0.8 and 0.9, respectively. An acceptable association was observed between P-ISYQOL and SRS-22r total scores (r = - 0.5, p < 0.01). The P-ISYQOL could discriminate between adolescents with spinal deformities and adolescents with no spinal deformity as well as those with different types of deformity and treatment (p < 0.01). CONCLUSIONS: The P-ISYQOL is a reliable and valid survey to assess the outcomes of adolescents with spinal deformities. LEVEL OF EVIDENCE: Level I-diagnostic studies.

Group-based telerehabilitation intervention using Wii Fit to improve walking in older adults with lower limb amputation (WiiNWalk): A randomized control trial.

OBJECTIVE: Determine efficacy of the novel WiiNWalk intervention on walking-related outcomes in older adults with lower limb amputation. DESIGN: Multi-site, parallel, evaluator-masked randomized controlled trial. SETTING: Home-setting in three Canadian cities. PARTICIPANTS: Community-dwelling lower limb prosthesis users over 50 years of age. INTERVENTIONS: The WiiNWalk group (n = 38) used modified Wii Fit activities for prosthetic rehabilitation. The attention control group (n = 33) used Big Brain Academy: Wii Degree, comprising of cognitive activities. Both groups completed a 4-week supervised phase with three 1-h sessions/week in groups of three overseen by a clinician via videoconferencing and a 4-week unstructured and unsupervised phase. MAIN MEASURES: Primary outcome was walking capacity (2 min walk test); secondary outcomes were balance confidence (activities-specific balance confidence scale), dynamic balance (four-step square test), and lower limb functioning (short physical performance battery). Outcomes were compared across time points with repeated measures analysis of covariance, adjusting for baseline and age. RESULTS: Mean age was 65.0 (8.4) years, with 179.5 (223.5) months post-amputation and 80% transtibial amputation. No group difference in a 2 min walk test with an effect size: 1.53 95% CI [-3.17, 6.23] m. Activities balance confidence was greater in the WiiNWalk group by 5.53 [2.53, 8.52]%. No group difference in the four-step square test -0.16 [-1.25, 0.92] s, nor short physical performance battery 0.48 [-0.65, 1.61]. A post-hoc analysis showed the greatest difference in balance confidence immediately after an unsupervised phase. CONCLUSIONS: The WiiNWalk intervention improved balance confidence, but not walking-related physical function in older adult lower limb prosthesis users. Future rehabilitation games should be specific to the amputation context.Clinical Trial Registration number, NCT01942798.

Validity of measures for life space mobility and physical activity in older adults with lower-limb amputation.

BACKGROUND: Older adults with lower-limb amputations (LLAs) often experience lack of confidence and poor balance, which limits their mobility. There are few validated measures for assessing these outcomes in the LLA population. OBJECTIVES: To assess the validity of the Life Space Assessment (LSA) and the Physical Activity Scale for the Elderly (PASE) for older adults with LLA. STUDY DESIGN: Secondary analyses of cross-sectional data. METHODS: Sixty-eight older adults with LLA across Canada were recruited to complete the LSA and the PASE. Validity was assessed via correlations with the Activities-specific Balance Confidence (ABC), Four-Square Step Test (FSST), and Two-Minute Walk Test (2-MWT). RESULTS: As hypothesized, the LSA was positively correlated with the ABC (ρ = 0.36, 95% confidence interval [CI] [0.17, 0.62]) and 2-MWT (r = 0.49, 95% CI [0.27, 0.70]) and negatively correlated with FSST (ρ = -0.39, 95% CI [-0.56, -0.10]). The PASE was positively correlated with the ABC (ρ = 0.34, 95% CI [0.10, 0.56]) and 2-MWT (ρ = 0.32, 95% CI [0.05, 0.52]), and negatively correlated with FSST (ρ = -0.36, 95% CI [-0.53, -0.07]). CONCLUSIONS: The LSA has validity in measuring life space mobility. The PASE captures the physical activity with weaker support of validity in older adults with LLA. CLINICAL RELEVANCE: The LSA and PASE are quick low-cost tools for clinicians to assess mobility-related functional health and physical activity, respectively, in older adults with LLA. However, the PASE may contain activities that are not common among older adults with LLA.

The Impact of COVID-19-Related Restrictions on Social and Daily Activities of Parents, People With Disabilities, and Older Adults: Protocol for a Longitudinal, Mixed Methods Study.

BACKGROUND: The COVID-19 pandemic has led to wide-scale changes in societal organization. This has dramatically altered people's daily activities, especially among families with young children, those living with disabilities such as spinal cord injury (SCI), those who have experienced a stroke, and older adults. OBJECTIVE: We aim to (1) investigate how COVID-19 restrictions influence daily activities, (2) track the psychosocial effects of these restrictions over time, and (3) identify strategies to mitigate the potential negative effects of these restrictions. METHODS: This is a longitudinal, concurrent, mixed methods study being conducted in British Columbia (BC), Canada. Data collection occurred at four time points, between April 2020 and February 2021. The first three data collection time points occurred within phases 1 to 3 of the Province of BC's Restart Plan. The final data collection coincided with the initial distribution of the COVID-19 vaccines. At each time point, data regarding participants' sociodemographics, depressive and anxiety symptoms, resilience, boredom, social support, instrumental activities of daily living, and social media and technology use were collected in an online survey. These data supplemented qualitative videoconference interviews exploring participants' COVID-19-related experiences. Participants were also asked to upload photos representing their experience during the restriction period, which facilitated discussion during the final interview. Five groups of participants were recruited: (1) families with children under the age of 18 years, (2) adults with an SCI, (3) adults who experienced a stroke, (4) adults with other types of disabilities, and (5) older adults (>64 years of age) with no self-reported disability. The number of participants we could recruit from each group was limited, which may impact the validity of some subgroup analyses. RESULTS: This study was approved by the University of British Columbia Behavioural Research Ethics Board (Approval No. H20-01109) on April 17, 2020. A total of 81 participants were enrolled in this study and data are being analyzed. Data analyses are expected to be completed in fall 2021; submission of multiple papers for publication is expected by winter 2021. CONCLUSIONS: Findings from our study will inform the development and recommendations of a new resource guide for the post-COVID-19 period and for future public health emergencies.

Telework and telerehabilitation programs for workers with a stroke during the COVID-19 pandemic: A commentary.

BACKGROUND: Due to the coronavirus disease 2019 (COVID-19) pandemic, rehabilitation facilities have become less accessible for patients with a stroke. Lack of early, intensive rehabilitation misses the opportunity for recovery during the critical time window of endogenous plasticity and improvement post-stroke. OBJECTIVES: The purpose of this commentary was to highlighting the benefits of telework and telerehabilitation programs for workers with a stroke during the COVID-19 pandemic. METHODS: Relevant publications regarding the management of individuals with a stroke, telerehabilitation and teleworking in the setting of COVID-19 were reviewed. RESULTS: Previous studies showed that telerehabilitation can effectively provide an alternate method of promoting recovery for patients with a stroke. With the physical distancing precautions in place for mitigating viral spread, teleworking can also provide a method for long term recovery and improvements in quality of life after a stroke. CONCLUSIONS: Overall, this commentary addresses the benefits of physically distant, safe and effective alternatives to support individuals who live with a stroke during COVID-19 pandemic.

The Effect of Telehealth Interventions on Function and Quality of Life for Older Adults with Pre-Frailty or Frailty: A Systematic Review and Meta-Analysis.

Telehealth interventions improve health outcomes by increasing access to care. We conducted a systematic review to synthesize evidence on the effect of telehealth interventions compared with no intervention or usual care for older adults with pre-frailty or frailty for physical function, quality of life (QOL), and frailty. We searched for randomized controlled trials (RCTs) in MEDLINE, PubMed, Embase, CINAHL, Cochrane, PsycINFO, and SPORTDiscus. Two authors reviewed records and assessed risk of bias. A narrative synthesis of findings was conducted. When appropriate, the standard mean difference (SMD) was used to compare telehealth interventions with control conditions. We used GRADE to determine the certainty of the evidence. Twelve RCTs were included. Low certainty evidence highlighted positive effects for the function and mental component of QOL favoring telehealth interventions (SMD = 0.31, 95% CI = [0.15, 0.47]; and SMD = 0.43, 95% CI = [0.22, 0.64], respectively). Despite a small positive effect of telehealth interventions, insufficient, and low certainty evidence precludes making definitive recommendations.

The comprehensive lower limb amputee socket survey: Reliability and validity of the persian version.

BACKGROUND: The Comprehensive Lower limb Amputee Socket Survey (CLASS) is a self-reported measure developed to assess prosthetic socket fit in individuals with lower limb amputation. OBJECTIVE: To assess the reliability and validity of the Persian version of the CLASS. STUDY DESIGN: Cross-sectional and repeated-measures. METHODS: We evaluated the translation and back translation of the CLASS and made the required changes according to expert committee feedback. Then, we recruited 124 participants with unilateral lower limb amputation (89.5% men). Internal consistency was analyzed with Cronbach's alpha and test-retest reliability using intra-class correlation coefficients. Convergent construct validity was assessed by comparing the CLASS scores with the Persian version of the Trinity Amputation and Prosthesis Experience Scales (TAPES) scores. In addition, known groups construct validity was assessed by comparing CLASS scores between groups with different causes and levels of amputation. RESULTS: Cronbach's alpha coefficient represented a very good internal consistency for all domains of the Persian CLASS (ranged from 0.86 to 0.92). The intra-class correlation coefficient for test-retest reliability for the Persian CLASS was good to excellent (ranged from 0.73 to 0.97). There was a significant correlation between the subscales of the Persian CLASS and satisfaction subscales of the Persian TAPES (p < 0.001). There was significant difference between comfort subscale of the Persian CLASS scores by level of amputation. CONCLUSION: The Persian CLASS is a reliable and valid measure for evaluating prosthetic socket fit.

The effect of local muscle vibration on clinical and biomechanical parameters in people with knee osteoarthritis: A systematic review.

Background: To identify and synthesize available published studies on the effect of local muscle vibration (LMV) on pain, stiffness, and function in individuals with knee OA. Methods: Five databases were searched to find relevant papers on April 29, 2020, including, PubMed, Scopus, EMBASE (Ovid), Science Citation Index, and COCHRANE Central Register for Controlled Trials (CENTRAL). Randomized controlled trials (RCTs) and nonrandomized-controlled-trials (non-RCTs), such as interrupted time series and prospective cohort studies were included. Two independent reviewers screened articles and assessed inclusion through predefined criteria. Participants' characteristics, study design, intervention characteristics, outcomes, and main results were collected independently by 2 reviewers. The risk of bias assessment of included studies was conducted using Cochrane risk of bias tools for RCTs and non-RCTs. Results: Six studies were included: 3 RCTs and 3 non-RCTs. The risk of bias in included studies was generally moderate to high. Improvement of pain, stiffness, and function following the application of LMV were reported in all studies. Conclusion: This review revealed the promising effect of LMV on pain, stiffness, function, and knee range of motion (ROM) improvements for individuals with knee Osteoarthritis (OA). However, further well-designed studies are required to have a convincing conclusion on the effect of LMV in individuals with knee OA.

Gait initiation and lateral wedge insole for individuals with early knee osteoarthritis.

BACKGROUND: People with knee osteoarthritis are at higher risk of postural deficits and locomotor adaptations which could be manifested in transient tasks like gait initiation. To better understand the effect of early knee osteoarthritis on gait initiation, we measured the gait initiation in two groups of early knee osteoarthritis and healthy age-matched controls and assessed the effect of lateral wedge insole in knee osteoarthritis group. METHODS: Twenty-one individuals with early knee osteoarthritis, mean (SD) age = 53.1 (7.4, years), and 19 age- and sex-matched asymptomatic healthy individuals, mean (SD) age = 47.5 (11.2, years), participated. Centre of pressure trajectories were used to quantify the two phases of gait initiation in barefoot condition: anticipatory postural adjustment, and locomotor phase. The immediate and four-week effect of lateral wedge insole and shod condition were also compared for individuals in knee osteoarthritis group. FINDINGS: Longer duration of anticipatory postural adjustment phase (P = 0.046), locomotor phase (P = 0.049), and total duration of gait initiation (P = 0.035) with lower length and velocity of the center of pressure trajectories in anticipatory postural adjustment phase (P = 0.002, and 0.008, respectively) were observed in knee osteoarthritis group compared to controls. Lateral wedge insole could increase the length and velocity of the centre of pressure in locomotor phase compared to barefoot condition (P = 0.001, and 0.002, respectively). INTERPRETATION: Our study outlined that people with early knee osteoarthritis adopt different gait initiation strategies mainly in postural preparation phase. The potential effect of lateral wedge insole was shown with better performance of the locomotor phase. CLINICAL TRIAL REGISTRY NUMBER: IRCT2016060628310N1.

The effect of a lateral wedge insole and a subtalar strap on gait parameters in knee osteoarthritis.

Background: Lateral wedge insole (LWI) aims to reduce loading on medial compartment of tibiofemoral joint in mild knee osteoarthritis (KOA). This effect may be augmented by concomitant use of subtalar strap to fix the ankle joint. Moreover, longitudinal arch support embedded in insoles can cause foot comfort and may be beneficial for people with KOA. Therefore, this study aimed to assess the immediate effect of LWI with an arch support with and without a subtalar strap on the kinetics and kinematics of walking in mild KOA. Methods: A convenient sample of 17 individuals with mild KOA (Kellgren and Lawrence grade II), aged ≥ 40 years were assessed in 3 conditions: without the insole; LWI; and LWI with a subtalar strap, where an arch support was embedded in all insoles. The primary outcomes were external knee adduction moment and angular impulse. The secondary outcomes were hip flexion and adduction moments, knee flexion angle, ankle eversion moment, and walking speed. The repeated measurements ANOVA was used to compare the primary and secondary outcomes between the conditions using SPSS. Significance level was set at 0.05. Results: LWI and a subtalar strap can significantly increase the knee flexion angle at 0%-15% of the stance phase compared to no insole (p<0.001). No other changes were observed (p=0.142). Conclusion: LWI with an arch, with or without a subtalar strap, cannot impose any immediate changes on the kinetics and kinematics of lower limb joints during walking in people with mild KOA.

Long-term symptoms and function after war-related lower limb amputation: A national cross-sectional study.

OBJECTIVE: The aim of this study was to document long-term symptoms and functional results following war-related knee disarticulation, trans-femoral amputation, and hip disarticulation. METHODS: An observational cross-sectional study was conducted in a 7-day recreational camp in Iran. One thousand patients with unilateral hip disarticulation, trans-femoral amputation and knee disarticulation due to war-related injuries were invited to undergo a thorough physical examination. Among the invited persons, 58.7% (587 subjects) responded to our invitations. A complete examination related to phantom pain, phantom sensation, stump pain, back pain, and sound limb joints pain with a self-constructed questionnaire was performed. In addition, Amputee Mobility Predictor (AMP) instrument with a prosthesis was completed to assess the function of patients. RESULTS: The mean duration of time since amputation was 22 years. The most common symptoms reported by participants were phantom sensation (82%), back pain (69%), and phantom pain (63%). In addition, total scores of AMP with a prosthesis in persons with knee disarticulation and trans-femoral amputations were 20.8 and 28, respectively. The knee disarticulation was associated with higher scores of AMP with a prosthesis compared to transfemoral amputation (p < 0.01). CONCLUSION: The results of this study showed that patients with lower limb amputation suffer from significant clinical and functional problems. The findings may be useful to adopt new strategies in planning rehabilitation programs to improve quality of life and health status of patients with war-related lower limb amputation. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Knee osteoarthritis at the early stage: The four-week effect of lateral wedge insole on pain and risk of falls.

Background: Knee osteoarthritis (KOA) is associated with a decrease in function, increase in pain and risk of falls. Lateral wedge insole (LWI) is commonly prescribed in KOA to improve pain and function. Our study aimed to 1) evaluate the clinical symptoms and risk of falls in early KOA and compare with controls; 2) evaluate the immediate and four-week effect of LWI. Methods: A sample of 20 Persian dwelling individuals with early KOA and 19 matched controls were recruited. Pain with Visual Analogue Scale (VAS), Quality of life (QOL) with the knee injury and osteoarthritis outcome score, risk of falls with the Timed Up and Go (TUG) and static One-leg Balance (OLB) tests were assessed. The four-week effect of 5º LWI was considered for individuals with KOA. Independent t-test was done to report the between-group differences, and paired t-test was used to report the four-week effect of LWI. Results: At baseline, statistically significant higher scores for pain, lower scores for QOL, and higher risk of falls were observed in KOA compared to controls (p< 0.001). A significant statistical decrease was observed in pain, and risk of falls, and an increase in QOL in KOA after four-week effect of LWI compared to baseline (p< 0.001). Conclusion: People with early KOA showed higher pain and lower level of QOL that were associated with higher risk of falls. LWI may have the potential to improve clinical symptoms and reduce the risk of falls at the early stage of KOA.

Genomic rearrangement screening of the BRCA1 from seventy Iranian high-risk breast cancer families.

BACKGROUND: The second leading cause of cancer deaths in women is breast cancer. Germline mutations in susceptibility breast cancer gene BRCA1 increase the lifetime risk of breast cancer. Eighty-one large genomic rearrangements (LGRs) have been reported up to date in BRCA1 gene, and evaluation of these rearrangements helps with precise risk assessment in high-risk individuals. In this study, we have investigated LGRs in BRCA1 among Iranian high-risk breast cancer families. MATERIALS AND METHODS: Seventy patients with breast cancer who were identified negative for point mutations or small deletions/insertions of BRCA1 gene were selected. Deletions and duplications of BRCA1 gene were evaluated using multiplex ligation-dependent probe amplification (MLPA). RESULTS: Two deletions, deletion of exons 1A/1B-2 and exon 24, were detected in two patients with breast cancer. The former alteration was found in a woman with a strong family history of breast cancer while the latter one was detected in a woman with early onset of breast cancer. CONCLUSION: Although our data confirm that LGRs in BRCA1 comprise a relatively small proportion of mutations in hereditary breast cancer in the Iranian population, MLPA analysis might be considered for screening of LGRs in high-risk individuals. It is worth to note that our results are consistent with previous studies in various Asian and European countries.

Quality of life in war-related hip disarticulation in Iran.

OBJECTIVE: The aim of the study was to evaluate health-related quality of life in veterans with hip disarticulation suffered during the Iran-Iraq War. METHODS: All war-related injured with hip disarticulation were invited to a 7-day recreational camp. Of 183 subjects, 76 participated in this study. The impact of hip disarticulation on quality of life was measured using the 36-item short form health survey and compared with the scores of the general public. RESULTS: Mean age at the time of interview was 44.1±6.98 years. The lowest score of health-related quality of life subscales was bodily pain (32.88±33.20). The health-related quality of life in veterans with hip disarticulation was significantly lower than the general public in all subscales (p<0.05), with the exception of vitality (p=0.114). CONCLUSION: Veterans with hip disarticulation due to war suffer from poor health-related quality of life. Appropriate interventions and rehabilitation programs are recommended to enhance quality of life in such patients.
