Reliability and validity of the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees.

BACKGROUND: Prosthetic embodiment is the perception of the prosthesis as a part of the body, and it is important for acceptance and adequate and effective use of the prosthesis. OBJECTIVE: The aim of this study was to investigate the validity and reliability of the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees. METHODS: This cross-sectional study included a total of 88 lower limb amputees. Internal consistency was evaluated using Cronbach α coefficient. The test-retest reliability of the scale, which was reapplied after 7-10 d, was evaluated using intraclass correlation coefficient. Principal component analysis with Varimax rotation was used to analyze the factor structure. Spearman correlation coefficient with Trinity Amputation and Prosthesis Experience Scale subscales was calculated for concurrent validity. RESULTS: The mean age of the participants was 45.13 ± 15.05 years, and 76.1% were male. Internal consistency (Cronbach α = 0.905) and test-retest reliability (intraclass correlation coefficient = 0.822) were high. 76.1% of the total variance could be explained by the 3 dimensions. Significant correlation was found with the Trinity Amputation and Prosthesis Experience Scale subscales (r = 0.542 for psychosocial adjustment subscale, r = -0.452 for activity restriction subscale, r = 0.490 for prosthesis satisfaction subscale, p < 0.001). CONCLUSIONS: The results of this study showed that the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees is a valid and reliable tool that can be used to evaluate prosthetic rehabilitation outcomes.

Incidence of Motoric Cognitive Risk Syndrome and Associated Factors in Older Adults in Türkiye.

Background: Motoric cognitive risk syndrome (MCRS) is characterized by slow gait and subjective cognitive decline. It is a predementia syndrome associated with an increased risk of dementia and mortality. Aims: To investigate the incidence of MCRS and its associated factors in older adults in Türkiye. Study Design: A retrospective study. Methods: This study enrolled community-dwelling older adults admitted to the geriatric outpatient clinic. Participants were assessed for MCRS according to previously described criteria. Logistic regression analysis was conducted to evaluate the association among MCRS and demographic features, clinical status, and geriatric syndromes. Results: Of the 1,352 older adults examined, 577 met the inclusion criteria, and the mean age was 75.2 years. The overall incidence of MCRS was 7.8%. The MCRS group was predominantly older, female, and unmarried, with polypharmacy and higher Deyo-Charlson comorbidity index and Yesavage geriatric depression scale scores than the non-MCRS group. In the multivariate model, significant associations were found between MCRS and age and polypharmacy [odds ratios (OR), 2.22; 95% confidence interval (CI), 1.04-4.71, p = 0.039; OR, 2.02; 95% CI, 1.02-3.99, p = 0.043, respectively]. Conclusion: The overall incidence of MCRS was found in 7.8% of older adults. Advanced age and polypharmacy are risk factors associated with MCRS.

A content comparison of 4 commonly used adult upper limb amputee outcome measurements with application of the refinements of International Classification of Functioning, Disability, and Health linking rules.

INTRODUCTION: The application of the refinements of linking rules to the outcome measurement methods provides an opportunity to obtain information concerning what the available instruments actually measure and how the instrument measures certain outcomes. The purpose of the study was to analyze the content of 4 commonly used upper limb amputee scales using the refined International Classification of Functioning, Disability, and Health (ICF) linking rules. METHODS: The Upper Extremity Functional Status module of the Orthotics and Prosthetics User Survey (OPUS-UEFS), Trinity Amputation and Prosthesis Experience Scales, Southampton Hand Assessment Procedure (SHAP), and Quick Disability of the Arm, Shoulder, and Hand were analyzed by 2 health professionals for a content comparison based on ICF categories. The Kappa statistic was used to calculate the degree of agreement between 2 professionals. RESULTS: The scale questions were linked with 43 different ICF codes in this study. Trinity Amputation and Prosthesis Experience Scale addresses all ICF domains. All items of SHAP and most items of OPUS-UEFS were linked to the activity-participation domain. Quick Disability of the Arm, Shoulder, and Hand items were linked with activity-participation and body function domains. The perspectives of OPUS-UEFS and SHAP are descriptive. The perspectives of Quick Disability of the Arm, Shoulder, and Hand were descriptive and appraisal. The perspectives of Trinity Amputation and Prosthesis Experience Scale subscales were descriptive, appraisal, and needs or dependency. Estimated kappa values ranged from 0.44 to 0.91 for ICF codes. CONCLUSIONS: Most concepts in the scales were frequently linked to the activity-participation domain. We think that the results of this study will be a useful guide to clinicians and researchers in selecting relevant and appropriate outcome measurements for upper limb amputee rehabilitation.

Validity, reliability, and Rasch analysis of the orthotics and prosthetics users' survey: Turkish version of the lower-extremity functional status.

BACKGROUND: It is well known that questionnaires and scales are easy to use, cheap, and provide fast results. In the clinical setting, it will be easier and more comfortable to evaluate lower-extremity functions in both prosthesis and orthosis users with a single questionnaire. OBJECTIVES: To study the Turkish version of the orthotics and prosthetics users' survey lower-extremity functional status (OPUS-LEFS) and investigate its reliability and validity in the Turkish prosthesis and orthosis users. STUDY DESIGN: After forward and backward translation process, test-retest, internal consistency, validity, dimensionality, and Rasch analysis were done for 139 participants. METHODS: Participants with a lower-limb prosthesis or orthosis were recruited in this study. Test and retest of the survey was done 1-3 days apart. For convergent validity, Nottingham Health Profile was used. Pearson correlation coefficient was used to analyze test-retest reliability; Cronbach's alpha for internal consistency, Spearman's correlation coefficient for validity, exploratory factor analysis by means of Kaiser-Meyer-Olkin and Bartlett's value of sphericity for dimensionality, and Rasch analysis were used. RESULTS: Test-retest reliability of OPUS-LEFS showed very strong correlation (0.994) and for internal consistency with Cronbach's alpha value 0.71 of the Turkish version of OPUS-LEFS. Analyses showed that OPUS-LEFS is valid ( p < 0.001) and significant ( p < 0.001). CONCLUSIONS: The Turkish version of the OPUS-LEFS has been shown to be a valid and reliable tool in evaluating both orthosis and prosthesis users with a self-administered questionnaire for LEFS.

Investigation of the correlation between knee joint position sense and physical functional performance in individuals with transtibial amputation.

INTRODUCTION: In individuals with transtibial amputation, the distal part of the lower extremity is lost. Therefore, the knee joint is of greater importance to be able to provide physical performance. The aim of this study was to evaluate the correlation between knee joint position sense and physical functional performance in individuals with transtibial amputation. METHODS: The study included 21 subjects with transtibial amputation. A digital inclinometer was used to evaluate the joint position sense of the amputated side knee joint. The timed up and go test, the 4-square step test, and 10-m walk test were used to evaluate physical functional performance. Linear regression analysis was used to investigate the associations between independent variables and functional performance tests. RESULTS: The mean age of the participants was 52.52 ± 15.68 years. The mean of the error in knee joint position sense was 5.33 degree (standard deviation = 3.08 degree). The error in knee joint position sense of the amputated limb predicted 45% of the variance in the 4-square step test and 22% of the variance in the 10-m walk test ( P < 0.05). CONCLUSIONS: The knee joint position sense on the amputated side was found to be associated with physical functional performance in individuals with transtibial amputation. Residual limb knee joint position sense should be considered when prescribing prostheses and planning rehabilitation programs.

The effects of cognitive versus motor concurrent task on gait in individuals with transtibial amputation, transfemoral amputation and in a healthy control group.

BACKGROUND: Lower limb amputation causes difficulties in mobility together with motor and sensory loss. Challenging situations such as concurrent tasks cause gait parameters to deteriorate. Understanding the effect of concurrent tasks on gait is important for the rehabilitation of amputees. RESEARCH QUESTION: Are the effects of concurrent cognitive and motor tasks on gait parameters at fixed speed different in individuals with transtibial amputation, or transfemoral amputation compared to healthy individuals? METHODS: The gait parameters were evaluated of 20 individuals with transtibial amputation, 13 individuals with transfemoral amputation and 20 healthy individuals while walking on a motorized treadmill under single task (ST), cognitive dual task (CDT) and motor dual task (MDT) conditions. The self-selected comfortable velocity, which was determined in the single-task gait, was used in all three walking tests. RESULTS: ST, CDT and MDT gait parameters of individuals with transtibial amputation, transfemoral amputation and healthy individuals were significantly different (p < 0.01). Covariance of step length variability increased in amputees when walking under MDT (p < 0.05). The dual task cost (DTC) for all the gait parameters was similar in all three groups (p > 0.05). The motor DTC of covariance of step length was greater than cognitive DTC (p < 0.05). SIGNIFICANCE: Individuals with lower limb amputation have the capacity to walk with cognitive and motor tasks without changing velocity on the treadmill, but concurrent motor tasks cause an increase in gait variability. The results of this study suggest that there is an increase in gait variability especially with motor tasks, which may cause a higher risk of falling. Trial number: NCT04392466 (clinicaltrials.gov).

Reliability and validity of the Turkish version of the satisfaction module of the Orthotics and Prosthetics Users' Survey.

BACKGROUND: Evaluation of prosthesis and orthosis (P&O) devices and service satisfaction in patients using P&O are important to understand the patient perspective and improve the quality of devices and the services. OBJECTIVE: The aim of this study was to translate the original Orthotics and Prosthetics Users' Survey (OPUS) satisfaction module into Turkish and examine its psychometric properties in lower limb P&O users. STUDY DESIGN: Cross-sectional study. METHODS: The Turkish versions of the OPUS-Client Satisfaction with Device (CSD) and Service (CSS) modules were applied to 157 individuals using a lower limb prosthesis or orthosis. The retest of the survey was applied 5-7 days later. Intraclass correlation coefficient was used to determine test-retest reliability, and Cronbach alpha was used to determine internal consistency. Criterion validity was evaluated using the Nottingham Health Profile. Exploratory factor analysis was used to examine the factor structure of the Turkish version of the OPUS satisfaction module. RESULTS: The test-retest correlation (intraclass correlation coefficient = 0.92 for CSD and 0.91 for CSS) and internal consistency (Cronbach's alpha = 0.84 for CSD and 0.95 for CSS) were high. A statistically significant correlation was found between the OPUS CSD and CSS modules and the Nottingham Health Profile (r = -0.325 for CSD module, r = -0.381 for CSS module, P < 0.001). The factor analysis revealed one-factor structure for both modules. CONCLUSIONS: This study demonstrated the reliability and validity of the Turkish version of the OPUS satisfaction module, and it provides a useful starting point for future studies on this survey.

Body image disturbance, psychosocial adjustment and quality of life in adolescents with amputation.

BACKGROUND: Physical and emotional situations experienced by amputees can affect body image and quality of life (QoL). Although adolescence is a time when appearance becomes more important, there are insufficient studies in literature examining the effect of body image disturbance (BID) on QoL and psychosocial adjustment in adolescents with amputation. OBJECTIVE: To investigate the BID, psychosocial adjustment and QOL in adolescents with amputation. METHODS: This cross-sectional study included individuals aged 11-18 years with amputation. The Amputee Body Image Scale was used to determine BID, the psychosocial adjustment subscale of Trinity Amputation and Prosthesis Experience Scale was used to investigate the psychosocial adjustment to amputation, and the Pediatric Quality of Life Inventory was used to determine the QoL. RESULTS: Evaluation was made of 42 adolescents (26 boys, 16 girls) with a mean age of 14.24 ± 2.25 years. Significant correlations were found between BID and age of fitting of the first prosthesis, psychosocial adjustment and QoL (p < 0.05). 38% of the variance of QoL was predicted by perceived body image and income of the family. 34% of the variance of psychosocial adjustment was predicted by perceived body image (p < 0.05). Adolescents suffering phantom limb pain were seen to have lower QoL scores (p < 0.05). CONCLUSION: BID is an important predictor of psychosocial adjustment and QoL in adolescent amputees. Therefore, a prosthesis that ensures the integrity of the body image should be fitted at an as early age as possible before the onset of body image disorder.

Investigation of the Effects of Dual-Task Balance Training on Gait and Balance in Transfemoral Amputees: A Randomized Controlled Trial.

OBJECTIVES: To investigate the effects of dual-task balance training on static and dynamic balance, functional mobility, cognitive level, and sleep quality in individuals with transfemoral amputation. DESIGN: Randomized controlled clinical trial. PARTICIPANTS: Transfemoral amputees (N=20). INTERVENTIONS: Participants were randomly assigned to the single-task gait and balance training group (n=10) or the dual-task gait and balance training group (n=10). Training was given in sessions of 60 min/d, 3 d/wk for 4 weeks. The single-task training group performed traditional gait and balance exercises, and the dual-task training group practiced cognitive and motor tasks while performing gait and balance exercises. MAIN OUTCOME MEASURES: The 1-leg stance test and the Four Square Step Test were used for balance assessment. The timed Up and Go test and 10-m walk test were used for gait assessment. Three test conditions to evaluate the training effects were single walking, walking while performing a cognitive task (serial subtraction), and walking while performing a motor task (tray carrying). The Montreal Cognitive Assessment scale was used for cognitive assessment and the Pittsburgh Sleep Quality Index for sleep quality assessment. RESULTS: Balance and mobility improved in both groups. Dual-task balance performance, functional mobility, and gait speed improved more in the dual-task training group after training (P<.05). Cognitive status and sleep quality improved significantly in the dual-task group (P<.05). CONCLUSIONS: Dual-task training was more effective than single-task training in the improvement of dual-task performance and cognitive status. The inclusion of dual-task exercises in the rehabilitation program of transfemoral amputees will provide a different perspective because of increased task automation.

Reliability and Validity of the Turkish Reintegration to Normal Living Index in Amputees.

In our country, outcome measures are needed to evaluate the results of occupational therapy in amputees. This study aimed to cross-culturally adapt the Reintegration to Normal Living Index (RNLI) and to evaluate the reliability and validity of a Turkish version of the RNLI. The Turkish version of the RNLI was applied to 120 amputees. Cronbach's alpha coefficient and the intraclass correlation coefficient (ICC) were used to determine internal consistency and test-retest reliability, respectively. Criterion validity was assessed using Short Form 36 (SF-36). The Turkish version of the RNLI presented reliable results in repeated assessments (ICC = .88), and the internal consistency of the RNLI was high (Cronbach's α coefficient = .89). A statistically significant relationship was found between RNLI and SF-36 (p < .05). The Turkish RNLI is a reliable and valid tool to evaluate the level of reintegration to normal living for amputees.
