Clinimetric properties of the SATIS-Stroke questionnaire in the Brazilian population: A satisfaction assessment measure addressing activities and participation after a stroke

BackgroundSATIS-Stroke questionnaire has been translated and adapted for use in the Brazilian population, however, it is necessary to test the measurement properties in Brazilian population.ObjectiveTo test the reliability, agreement, concurrent validity, and diagnostic accuracy of the SATIS-Stroke.MethodsChronic stroke survivors were included. The calculations were made using scores in logits (Rasch Model). Reliability was tested using the intraclass correlation coefficient (ICC_2,1), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plots. Concurrent validity was analyzed using Spearman's correlation coefficient. For such, the correlation between SATIS-Stroke and Stroke Specific Quality of Life (SS-QOL) questionnaires was determined. Diagnostic accuracy was estimated based on the area under the receiver operating characteristic (ROC) curve with a 95% confidence interval and considering the sensitivity and specificity of SATIS-Stroke in differentiating different types of activity and participation.ResultsEighty stroke survivors were analyzed. Mean age was 57.98±13.85 years and 45.2% had severe impairment. Excellent reliability was found (intra-observer ICC_2,1 = 0.90; 95% CI: 0.84, 0.93; inter-observer ICC_2,1 = 0.89; 95% CI: 0.83, 0.93). The Bland-Altman plot demonstrated satisfactory agreement. In the analysis of concurrent validity, a strong, positive, significant correlation was found between SATIS-Stroke and SS-QOL (r_s = 0.74; p <0.001 with an r²=0.44; p=0.001). Diagnostic accuracy was satisfactory, with 80.8% sensitivity and 85.2% specificity.ConclusionThe Brazilian version of the SATIS-Stroke questionnaire exhibited adequate reliability, concurrent validity, and diagnostic accuracy. Therefore, this is a valid, reproducible measure for the assessment of satisfaction with regard to activities and participation following a stroke.

Reduced version of the Activity Measure for Post-Acute Care (AM-PAC) for inpatients, “6-clicks”: Brazilian-Portuguese cross-cultural adaptation and measurement properties

BackgroundThe “6-clicks” is the reduced version of the Activity Measure for Post-Acute Care for inpatients that assesses limitations in basic mobility, daily activity, and applied cognitive, simply and quickly.ObjectiveCross-culturally adapt the “6-clicks” into Brazilian-Portuguese and verify its measurement properties.MethodsCross-cultural adaptation followed recommendations from international guidelines. Reliability indices, standard error of measurement and minimum detectable difference were calculated. Participants included 13 professionals, 13 patients and 13 companions. Test of measurement properties involved 101 patients’ of both sexes, hospitalized in the infirmary, under physical therapy care, able to understand and respond to commands and with no discharge expectation. Their 30 companions were also included.ResultsMinor changes implemented to the original version. The three domains showed adequate internal consistency (α > 0.65). Inter-rater reliability (n = 50) and test–retest reliability, when administer to patients (n = 51) and to companions (n = 30), showed good for basic mobility domain (ICC_2.1 = 0.81, 0.83 and 0.82, respectively), good to moderate for daily activity (ICC_2.1 = 0.78 and ICC_3.1 = 0.71 and 0.82, respectively) and moderate to poor for applied cognitive (ICC_2.1 = 0.64, 0.36 and ICC_3.1 = 0.63), respectively. The highest agreements among patients/companions were also in basic mobility. Standard error of measurement ranged from 2.03 to 2.64 while the minimum detectable difference ranged from 5.63 to 7.32.ConclusionTranslated and adapted Brazilian version of the “6-clicks” showed acceptable measurement properties. The functional data provided by the instrument could be used to enhance care and help treatment follow-up.     

Ultrasound imaging of the serratus anterior muscle at rest and during contraction

The purpose of this study is to describe a clinically feasible method for measuring the thickness of the serratus anterior (SA) muscle using rehabilitative ultrasound imaging (RUSI) and to determine the reliability of repeated measures of that method. An exploratory clinical measurement study using a test–retest methodology was utilized to determine the reliability of the measurements in a sample of 20 healthy subjects. While sitting with the arm flexed 120°, the SA of each subject was imaged at rest, during an active hold and while holding a three pound weight. On Day 1, images were repeated three times for each condition by the same examiner. On Day 2, Examiner 1 and Examiner 2 repeated the scans. Images were examined offline by Examiner 1 with SA thickness measured superior to the most distal rib in the image. Reliability was evaluated using intraclass correlation coefficients (ICCs) and Bland–Altman plots. The intra‐examiner reliability (same day) during rest, active hold and active hold with resistance was ICC_3,3 = 0·892; ICC_3,3 = 0·951; and ICC_3,3 = 0·869–0·971, respectively. Intra‐examiner reliability between days ranged from ICC_3,2 = 0·613 at rest to ICC_3,2 = 0·736 during active hold with resistance. Interexaminer reliability was moderate during active hold (ICC_2,2 = 0·526) and active hold with resistance (ICC_2,2 = 0·535) and poor during rest (ICC_2,2 = 0·425). This study demonstrates that SA thickness can be measured reliably using RUSI by the same examiner and suggests that active movements may increase that reliability.     

Measurement properties of the Brazilian Portuguese anterior cruciate ligament - return to sport after injury (ACL-RSI) scale short version after anterior cruciate ligament reconstruction

BackgroundHigher scores (closer to 100) on the Anterior Cruciate Ligament - Return to Sport after Injury (ACL-RSI) scale indicate better psychological readiness to return to sport after anterior cruciate ligament reconstruction (ACLR).ObjectivesTo verify the validity and reliability of the ACL-RSI-short version (ACL-RSI-SV) in Brazilian Portuguese in individuals who underwent ACLR.MethodsParticipants (n=168) answered the Brazilian versions of ACL-RSI, Tampa Scale for Kinesiophobia (TSK-17), and International Knee Documentation Committee (IKDC) to assess the convergent validity of the short version. Internal consistency was also verified through correlation between items. Scores of participants who did not return to sport, who returned at a lower level, and at the pre-injury level were compared to verify divergent validity. ACL-RSI was answered again after 5-8 days to verify test-retest reliability.ResultsACL-RSI-SV in Brazilian Portuguese showed good test-retest reliability (ICC_2.1 = 0.85, 95% CI: 0.76, 0.90) and acceptable internal consistency (Cronbach's alpha = 0.78). Standard error of measurement (SEM) and smallest detectable change (SDC) were 4.98 and 13.82. High positive correlation was found with the full version of the ACL-RSI (r=0.93, 95% CI: 0.91, 0.95), moderate positive correlation with the IKDC (r=0.52, 95% CI: 0.40, 0.62), and weak negative correlation with the TSK-17 (r = -0.45, 95% CI: -0.60, -0.28). It also presented good divergent validity to identify individuals who returned to sport.ConclusionACL-RSI-SV in Brazilian Portuguese is a consistent, valid, and reliable instrument to assess patients who have undergone ACLR, with good ability to identify those who return to sport.     

Translation of the short version of the Smartphone Addiction Scale into Brazilian Portuguese: cross-cultural adaptation and testing of measurement properties

BackgroundSmartphone use has been constantly increasing. Smartphone addiction can lead to changes in the emotional state and musculoskeletal system of users. To identify smartphone addicts, the Smartphone Addiction Scale-Short Version was developed; however, this scale has not been translated into Brazilian Portuguese and tested for its measurement properties.ObjectiveTo translate and cross-culturally adapt the Smartphone Addiction Scale-Short Version into Brazilian Portuguese; to assess the internal consistency, reliability and construct validity of the scale among university students.MethodsThe cross-cultural adaptation was performed following the guidelines for cross-cultural adaptation of self-report measures, and data were collected via online surveys administered to 59 university students over 18 years of age for test–retest. To test the measurement properties of the final version of the Smartphone Addiction Scale-Short Version, a convenience sample including 130 university students was used.ResultsThe Smartphone Addiction Scale-Short Version showed good reliability for test–retest scores (ICC_3,1 = 0.82; 95% CI = 0.70–0.89) and good internal consistency considering all 10 items (Cronbach's alpha = 0.95). The construct validity was calculated comparing the Smartphone Addiction Scale-Short Version score to data from a questionnaire prepared by the authors of this study, including frequency per day (r = 0.35; p < 0.001), leisure time on the smartphone (r = 0.33; p < 0.001), and time working on the smartphone (r = 0.18; p = 0.04) that were significantly positively associated with higher Smartphone Addiction Scale-Short Version scores. The results show a high prevalence of smartphone addiction among university students (33.1%).ConclusionIt can be concluded that the Brazilian Portuguese version of the Smartphone Addiction Scale-Short Version is a reliable and valid tool for screening smartphone addiction in university students.     

Brazilian Version of Cancer Fatigue Scale: Validation of the Brazilian Version of Cancer Fatigue Scale in Patients With Breast Cancer

ContextScales to assess the fatigue in patients with cancer may help the clinical decision-making process.ObjectivesThe objective of this study was to cross-culturally adapt and determine the validity of the Brazilian version of Cancer Fatigue Scale.MethodsTranslation and cross-cultural adaptation followed the recommendations of international guidelines. One hundred fifty-one women with breast cancer participated in the validity phase and they filled out the Brazilian version of another instruments (Piper Fatigue Scale Revised, Beck Depression Inventory, Verbal Numerical Rating Scale, and Karnofsky Performance Scale). The measurement properties of reliability, internal consistency, and validity were measured.ResultsThe few discrepancies identified in the back-translation were solved by consensus, and the Cancer Fatigue Scale was successfully translated and cross-culturally adapted. The Brazilian version of Cancer Fatigue Scale showed good stability (test-retest reliability intraclass correlation coefficient = 0.95, 95% CI = 0.94–0.97 and interexaminer reliability intraclass correlation coefficient = 0.98, 95% CI = 0.97–0.99) and good internal consistency (Cronbach's alpha >0.70 for the three subscales/domains). The high correlation was found with Piper Fatigue Scale (r = 0.643) and Beck Depression Inventory (r = 0.509) in terms of validity. However, a reasonable correlation was found with Verbal Numerical Rating Scale (r = 0.302) and Karnofsky Performance Scale (r = −0.324).ConclusionHere, we validated the Cancer Fatigue Scale in breast cancer Brazilian women meaning its use for the identification and evaluation of cancer-related fatigue in patients with breast cancer.     

Reliability and internal consistency of the Swedish version of the MAastrIcht Nurses Activities INventory (MAINtAIN(S)) – A pilot testing of the tool

ObjectivesTo evaluate the test–retest reliability and internal consistency of the Swedish version of the MAastrIcht Nurses Activities INventory (MAINtAIN(S)) developed to measure nursing staff perceived behaviours and barriers for promotion of everyday activities in nursing home residents.MethodNursing staff completed the MAINtAIN(S) questionnaire on two occasions at 3-week intervals. Relative reliability, absolute reliability and internal consistency with Cronbach's alpha were calculated.ResultsThe test-–retest reliability of MAINtAIN(S)-behaviours subscales ranged from ICC_2. = 0.78-–0.91 and MAINtAIN(S)-barriers subscales from ICC_2.1 = 0.60-–0.84. Cronbach's alpha varied between 0.60 and 0.91 for the different subscales. The MAINtAIN(S) inventory shows acceptable reliability and internal consistency. MAINtAIN(S) seems to be a promising tool for identifying behaviours and barriers in promoting everyday activities in nursing home residents and can be used to develop ward specific interventions for promotion of daily physical activity level in the care of older adults.     

Scapular motion is accelerated in asymptomatic individuals with dyskinesis: An observational study

IntroductionIndividuals with shoulder and upper extremity pathology often present with altered scapular motion. Few studies have looked at variations in scapular acceleration as a way of quantifying scapular motion. The purpose was to determine the effectiveness of wireless accelerometers for detecting changes in acceleration in individuals with scapular dyskinesis.Materials/methodsTwenty-seven asymptomatic college students (mean age 24 (SD ± 1.54), 65% female, 93% right handed) were visually screened for scapular dyskinesis using previously described criteria. Of the students recruited, fifteen students were determined to have scapular dyskinesis. After securing a wireless accelerometer (MyoResearch 3D DTS) on the dominate scapula, the participants performed five repetitions of standing scaption from 0 to 140°. Linear scapular accelerations along three orthogonal axes (frontal-y, transverse-z, and sagittal-x) were collected. Intraclass correlation coefficients (ICC_{3, k}) were used to determine the between day intra-rater reliability while a one-way analysis of variance was used to determine differences in acceleration between those with and without dyskinesis.ResultsThere was good between day intra-rater reliability for the average of all three axes (ICC = 0.79) and for the x and y axes (ICC > 0.78). Reliability was poor (ICC = 0.31) for the z-axis. There was a significant increase in overall acceleration of the scapula in those with dyskinesis (p = .039). There was also a significant increase in acceleration along the y-axis for those with dyskinesis (p = .003) but not for the other axes (p > .16).ConclusionWireless accelerometers reliably quantify scapular acceleration in healthy individuals. In a healthy population with dyskinesis, the overall magnitude of scapular acceleration was greater when compared to a healthy group without dyskinesis.     

Translation,cross-cultural adaptation and validity of the Brazilian version of the Foot and Ankle Ability Measure questionnaire

Purpose: To translate and cross-culturally adapt the Foot and Ankle Ability Measure (FAAM) questionnaire and verify the psychometric properties of the Brazilian–Portuguese version of this instrument.

Methods: Analysis of validity was carried out by applying the Rasch model and evaluating correlations with the Short Form-36 (SF-36) Physical Function (PF) subscale. Test–retest reliability and internal consistency were analyzed with the intraclass correlation coefficient (ICC_2,1) and Cronbach’s alpha tests, respectively.

Results: Ninety subjects with various foot and ankle musculoskeletal disorders (age 37.05 SD 10.49 years) were included. The ICC_2,1 was 0.88 and 0.82 with Cronbach’s alphas of 0.93 and 0.90 for the “Activities of Daily Living” (ADL) and “Sports” subscales, respectively. Correlations with the SF-36 PF were 0.78 (p?95: 0.62–0.87) and 0.65 (p?95: 0.45–0.79) for the ADL and Sports subscales, respectively. Item reliability indices in Rasch analysis were 0.91 (ADL) and 0.84 (Sports). Three items from the ADL subscale (14.2%) did not match the expectations of the model. All items from the Sports subscale fit the model.

Conclusions: There is evidence of validity and reliability of the FAAM-Brazil. Rasch analysis indicated that three items of the ADL subscale did not fit the model in the sample studied.

• Implications for Rehabilitation

• Self-report questionnaires are commonly used in both clinical practice and research because of their ability to efficiently collect information. If the instrument is created properly, the information collected can be used to interpret the effect of clinical conditions on physical function.

• The Foot and Ankle Ability Measure (FAAM) is an evaluative instrument that assesses functional limitations for those with foot- and ankle-related disorders. It was translated into four languages and has evidence of validity, reliability, and responsiveness.

• Evidence of validity and reliability is provided for the FAAM-Brazil when applied to subjects with a wide range of foot and ankle musculoskeletal disorders.

     

The effect of Therapeutic Touch on Back Pain in Adults on a Neurological Unit: An Experimental Pilot Study

BackgroundChronic back pain affects many aspects of everyday life and is a common reason for medical visits, leading to high direct and indirect health care costs. Innovative and cost-effective nonpharmacologic pain management methods should be promoted to ensure adequate treatment.AimsThe aim of this pilot study was to investigate the pain-relieving effect of Therapeutic Touch in adult neurologic patients with back pain.DesignA pretest–post-test randomized controlled trial.SettingsA university hospital in Austria.Participants/SubjectsPatients with back pain diagnosis (N = 29) on hospital admission.MethodsA pilot study was conducted for 3 months. The control group (n = 14) received the pharmacologic pain management recommended by the World Health Organization; patients in the intervention group (n = 15) received additionally four Therapeutic Touch treatments on 4 consecutive days. The Quebec Back Pain Disability Scale and the Numeric Pain Rating Scale were used as outcome measures to evaluate activity domains affected by back pain and pain intensity.ResultsPain improvement was found in the intervention group according to the mean score of the Quebec Back Pain Disability Scale (day 1: 72.53, standard deviation [SD] ± 14.10; day 4: 39.47, SD ± 8.77; p < .001). The Numerical Pain Rating Scale score averaged 4.33 points (SD ± 2.09) on the first day and 2.47 points (SD ± 1.12) on the fourth day. The long-term effect of Therapeutic Touch was significant and indicated a major effect (Pillai's trace = .641, F_(3.12) = 7.1, p = .005, η_p² = .641).ConclusionsTherapeutic Touch seems to be a noninvasive nursing intervention for back pain management to provide more professional patient care.     

Reliability of the Thai version of the International Physical Activity Questionnaire Short Form in chronic obstructive pulmonary disease

ObjectiveTo determine the reliability of the Thai version of International Physical Activity Questionnaire Short Form (IPAQ-SF) in Chronic Obstructive Pulmonary Disease (COPD) patients.MethodsA cross sectional study was carried out in COPD subjects at Chiang Dao hospital, Chiang Mai, Thailand in June and July 2019. COPD subjects were asked to complete the Thai version of the IPAQ-SF. Calculations for each level of activity were carried out separately (vigorous activity, moderate activity, walking, and sitting). This was carried out twice with an interval of four weeks between visits. The test–retest reliability of the IPAQ was assessed using the intraclass correlation (ICC) with a 95% confidence interval (CI). Cohen's kappa coefficient and percentage agreement were used to test the repeatability of the physical activity classification between the two visits.ResultsSixty COPD subjects (50% male), with a mean age of 71.2 ± 7.7 years were included. The least reliability was established for sitting time (ICC = 0.439; 95%CI; 0.212, 0.621, p-value < 0.001) and the greatest for the total physical activity (ICC = 0.837; 95%CI; 0.741, 0.899, p-value < 0.001). The Kappa statistic was 0.433 with a 95%CI; 0.237, 0.639, p-value < 0.001 and the percentage agreement of the physical activity classification between the two visits was 66.7%.ConclusionThe test–retest reliability was adequate for vigorous activity and total physical activity. Although there are concerns about the agreement for classification of physical activity, the IPAQ-SF may be a useful if not definitive tool for assessing physical activity in COPD.     

Efficacy of foam rolling with additional vibration stimulation on the mobility of the thoracolumbar fascia. An observational study

IntroductionObservations show that foam rolling improves joint movements. Likewise, it can be stated that a vibration stimulation of the tissue leads to improved joint mobility.MethodThis study investigates whether the combination of foam rolling and vibrations (31 Hz) can influence the sliding of the thoracolumbar fascia more effectively than normal foam rolling. 45 subjects participated in the study and were divided into a foam roll with additional vibration group (FRV), a foam roll group (FR) and a control group (CG). The intervention groups rolled out the gluteal muscles, the lateral trunk and the upper and lower back. Mobility measures were taken pre and post the respective intervention. Subsequent cross correlation software analysis quantified the sliding of the fascia and calculated its shear strain mobility (SSM).ResultsThe sliding of the thoracolumbar fascia improved significantly within the FRV by 2.83 mm (SD ± 1.08/p < .001), in the FR by 0.96 mm (SD ± 0.43/p < .001) and in the CG decreased the sliding by 0.1401 mm (SD ± 0.28/p = .076). The fascia/fascia SSM increased in the FRV by 22.61% (SD ± 15.64/p < .001), in the FR by 11.41% (SD ± 20.38/p = .056) and in the CG decreased the SSM by 0.9473% (SD ± 11.35/p < .751). The lumbar movement increased in both intervention groups, but showed no significant result.ConclusionThe use of a foam roll with additional vibration and standard intervention have increased thoracolumbar fascia sliding and lumbar movements. The improved shear strain mobility can be attributed to the multi-activity of mechanoreceptors, such as Pacini- and Ruffini-Bodies.     

Transcultural adaptation and validation of Hindi version of Quebec Back Pain Disability Scale

Abstract

Purpose: To transculturally adapt the Quebec Back Pain Disability Scale for Hindi-speaking population and examine its psychometric properties in patients with low back pain.

Materials and methods: The Quebec Back Pain Disability Scale was translated and cross-culturally adapted into Hindi following international guidelines. Hindi version of the scale was completed by 120 patients with low back pain and 60 healthy controls. Patients with low back pain were also administered the Hindi-Roland Morris Disability Questionnaire and Visual Analog Scale. Psychometric evaluation included test–retest reliability, convergent and discriminative validity. Exploratory factor analysis was carried out to determine the factor structure.

Results: The factorial analysis revealed a four-factor solution (bending/carrying, ambulation/reach, prolonged postures and rest). Convergent validity was confirmed by high correlation of Hindi Quebec Back Pain Disability Scale to the Hindi version of Roland Morris Disability Questionnaire (r?=?0.77 and p?<?0.001) as well as Visual Analog Scale (r?=?0.682 and p?<?0.001) scores. Discriminative validity was established by significantly different scores for patients with low back pain and the healthy controls (35.36?±?18.6 vs. 9.13?±?6.08 and p?<?0.001). The translated version of the scale showed remarkable internal consistency (Cronbach α?=?0.98) and the intraclass correlation coefficient of test–retest reliability was excellent (ICC_2,1=0.96). MDC₉₅ and SEM scores obtained were 10.28 and 3.71, respectively.

Conclusion: The Hindi version of Quebec Back Pain Disability Scale has good test–retest reliability, discriminative and convergent validity and is appropriate for clinical and research use in Hindi-speaking low back pain patients.

• Implications for rehabilitation

• Linguistically and culturally adapted questionnaires help researchers make adequate inferences about instruments measuring health and quality of life.

• The translated version would serve as a valid research tool allowing comparability of data across cultures thus, providing opportunities for large multicenter, multicountry trials.

• A Hindi Quebec Back Pain Disability Scale version will help to improve the quality and efficacy of assessment of low back pain by developing in patients, a better understanding of the items which can be easily correlated with the activities of daily living.

     

Assessment of the reproducibility of the indirect ultrasound method of measuring diaphragm mobility

The aim of this study was to assess the reproducibility of the ultrasound (US) measurement of craniocaudal displacement of the left branch of the portal vein as an indirect method of measuring right hemidiaphragm mobility in healthy young adults. Forty‐one healthy participants were selected, ranging from 20 to 30 years of age. The US tests were conducted and interpreted by two observers (A and B) on two separate occasions (Test 1 and Test 2). Intra‐observer and interobserver reproducibility and repeatability of US measurements were determined by the intraclass correlation coefficient (ICC_[2,1]) using a 95% confidence interval (CI). Interobserver reproducibility assessment showed ‘high correlation’ for Test 1 and Test 2 (ICC_[2,1] = 0·83, 95% CI = 0·70–0·91, and ICC_[2,1]  = 0·79, 95% CI = 0·61–0·89, respectively). Intra‐observer reproducibility assessment showed ‘moderate correlation’ for observer A (ICC_[2,1]  = 0·69, 95% CI = 0·45–0·84) and for observer B (ICC_[2,1]  = 0·65, 95% CI = 0·39–0·81). Repeatability assessment showed ‘high correlation’ for all tests performed (ICC_[2,1]  = 0·86, 0·80, 0·74, 0·79, P<0·001). In conclusion, US measurement of craniocaudal displacement of the left branch of the portal vein is a reproducible method of measuring right hemidiaphragm mobility in healthy young adults.     

Reliability of the Modified CKCUEST and correlation with shoulder strength in adolescent basketball and volleyball players

BackgroundPhysical performance tests provide a more complete picture of the functional status of the athlete's upper extremity.ObjectivesThe primary purpose was to evaluate the reliability of the Modified Closed Kinetic Chain Upper Extremity Stability Test (MCKCUEST) in adolescent volleyball and basketball players. The secondary objective was to evaluate the relationship between the MCKCUEST and shoulder rotation isometric strength in this population.MethodsSeventy-three healthy basketball (n = 39) and volleyball (n = 34) players participated to establish the reliability and correlations of the MCKCUEST. We used a two-session measurement design to evaluate the reliability of the MCKCUEST. Shoulder rotation isometric strength was performed to determine relationships with the MCKCUEST.ResultsThe intraclass correlation coefficients (ICC_2,1) for intra-session reliability of the MCKCUEST ranged from 0.86 to 0.89, and the between days test–retest reliability (ICC_3,1) was 0.93. The standard error of measurement (1 touch) and the minimal detectable change (3 touches) showed clinically acceptable absolute reliability values. A weak correlation was found between the MCKCUEST power score and shoulder rotation isometric strength (r values between 0.3 and 0.4).ConclusionsResults demonstrated good to excellent relative reliability and clinically acceptable absolute reliability values for the MCKCUEST on adolescent basketball and volleyball athletes. Performances on the MCKCUEST were weakly associated with shoulder rotation strength.     

Reliability,validity and minimal detectable change of the Mini-BESTest in Greek participants with chronic stroke

Objectives: This study aimed to investigate the psychometric characteristics of reliability, validity and ability to detect change of a newly developed balance assessment tool, the Mini-BESTest, in Greek patients with stroke. Design: A prospective, observational design study with test-retest measures was conducted. Methods: A convenience sample of 21 Greek patients with chronic stroke (14 male, 7 female; age of 63 ± 16 years) was recruited. Two independent examiners administered the scale, for the inter-rater reliability, twice within 10 days for the test-retest reliability. Bland Altman Analysis for repeated measures assessed the absolute reliability and the Standard Error of Measurement (SEM) and the Minimum Detectable Change at 95% confidence interval (MDC_95%) were established. The Greek Mini-BESTest (Mini-BESTest_GR) was correlated with the Greek Berg Balance Scale (BBS_GR) for assessing the concurrent validity and with the Timed Up and Go (TUG), the Functional Reach Test (FRT) and the Greek Falls Efficacy Scale-International (FES-I_GR) for the convergent validity. Results: The Mini-BESTestGR demonstrated excellent inter-rater reliability (ICC (95%CI) = 0.997 (0.995–0.999, SEM = 0.46) with the scores of two raters within the limits of agreement (mean_dif = ?0.143 ± 0.727, p > 0.05) and test-retest reliability (ICC (95%CI) = 0.966 (0.926–0.988), SEM = 1.53). Additionally, the Mini-BESTest_GR yielded very strong to moderate correlations with BBS_GR (r = 0.924, p < 0.001), TUG (r = ?0.823, p < 0.001), FES-I_GR (r = ?0.734, p < 0.001) and FRT (r = 0.689, p < 0.001). MDC₉₅ was 4.25 points. Conclusion: The exceptionally high reliability and the equally good validity of the Mini-BESTest_GR, strongly support its utility in Greek people with chronic stroke. Its ability to identify clinically meaningful changes and falls risk need further investigation.     

Cross-cultural adaptation and Rasch validation of the Slovene version of the Orthotics and Prosthetics Users’ Survey (OPUS) Client Satisfaction with Device (CSD) in upper-limb prosthesis users

ObjectiveTo validate the Slovene version of the Orthotics and Prosthetics Users’ Survey (OPUS) 8-item Client Satisfaction with Device (CSD) questionnaire in upper-limb prosthesis users and to further verify measurement properties of this tool with Rasch analysis.DesignParticipants consisted of a convenience sample of 76 adults (54 men) using a prosthesis after unilateral upper-limb amputation who consecutively attended a follow-up visit at our centre.MethodsAfter translation and cross-cultural adaptation of the CSD into the Slovene language, we evaluated functioning of the rating scale categories, item fit (internal construct validity), reliability indices and dimensionality, as well as convergent and discriminant construct validity of the questionnaire.ResultsRasch analysis indicated that: (1) functioning of the 4 response options was acceptable; (2) all items fitted the measured construct [information-weighted (infit) and outlier-sensitive (outfit) mean-square statistics 0.60 to 1.40]; (3) person separation reliability was 0.62 (and Cronbach α = 0.76), item separation reliability was 0.83; (4) on principal component analysis (PCA) on the standardised residuals, the CSD showed borderline but acceptable unidimensionality and no local item dependency. Moreover, as expected, the CSD score showed good correlation with the QUEST 2.0 score (r_s = 0.57) and little to fair correlation with the OPUS Upper Extremity Functional Status score (r_s = 0.21).ConclusionThe metric properties of the Slovene version of CSD agree with previous studies. The present study confirms the validity of CSD for measuring patient satisfaction with an upper-limb device, enhances the confidence in this tool for assessing upper-limb prosthesis users, and contributes to further refining the technical quality of this measure.     

Cross-cultural validity of the Animated Activity Questionnaire for patients with hip and knee osteoarthritis: a comparison between the Netherlands and Brazil

BackgroundThe Animated Activity Questionnaire (AAQ) was developed in the Netherlands to assess activity limitations in individuals with hip/knee osteoarthritis (HKOA). The AAQ is easy to implement and minimizes the disadvantages of questionnaires and performance-based tests by closely mimicking real-life situations. The AAQ has already been cross-culturally validated in six other countries.ObjectiveTo assess the cross-cultural validity, the construct validity, the reliability of the AAQ in a Brazilian sample of individuals with HKOA, and the influence of formal education on the construct validity of the AAQ.MethodsThe Brazilian sample (N = 200), mean age 64.4 years, completed the AAQ and the Western Ontario and McMaster Universities Index (WOMAC). A subgroup of participants performed physical function tests and completed the AAQ twice with a one-week interval. The Dutch sample (N = 279) was included to examine Differential Item Functioning (DIF) between the scores obtained in the Netherlands and Brazil. For this purpose, ordinal regression analyses were used to evaluate whether individuals with the same level of activity limitations from the two countries (the Dutch as the reference group) scored similarly in each AAQ item. To evaluate the construct validity, correlation coefficients were calculated between the AAQ, the WOMAC domains, and the performance-based tests. To evaluate reliability, the Cronbach's alpha coefficient, the intraclass correlation coefficient, and the standard error of measurement (SEM) were calculated.ResultsThe AAQ showed significant correlations with all the WOMAC domains and performance-based tests (rho=0.46–0.77). The AAQ showed high internal consistency (Cronbach's alpha=0.94), excellent test-retest reliability (ICC_2,1 = 0.98), and small SEM (2.25). Comparing to the scores from the Netherlands, the AAQ showed DIF in two items, however, they did not impact on the total AAQ score (rho=0.99).ConclusionOverall, the AAQ showed adequate cross-cultural validity, construct validity, and reliability, which enables its use in Brazil and international/multicenter studies.     

Examination of the Effects of 4-Hour Nonvalved Filtering Facepiece Respirator Use on Blood Gas Values of Health Care Professionals: A Before and After Study

IntroductionThe use of personal protective equipment increased rapidly during the COVID-19 pandemic that began in 2019. The purpose of this study was to examine the effects of uninterrupted 4-hour use of internationally certified nonvalved filtering facepiece respirators on venous blood gas in health care workers during the COVID-19 pandemic.MethodsA before-after design included venous blood gas analyses collected at the beginning of shifts before nonvalved filtering facepiece respirator had been put on and after 4-hour uninterrupted use of nonvalved filtering facepiece respirator.ResultsIn this study, 33 volunteer health care workers took part. In terms of blood gas values, mean pCO₂ values were 47.63 (SD = 5.16) before and 47.01 (SD = 5.07) after nonvalved filtering facepiece respirator use, mean HCO₃ values were 23.68 (SD = 1.10) in first blood gas analysis and 24.06 (SD = 1.31) in second blood gas analysis, and no significant difference was observed between before and after the use of nonvalved filtering facepiece respirator (t = 0.67, P = .50, t = ?2.0, P = .054, respectively). The only significant difference in parameters investigated between the groups was in pH levels, at pH = 7.35 (SD = 0.29) before and pH = 7.36 (SD = 0.20) after nonvalved filtering facepiece respirator use (t = ?2.26, P = .03).ConclusionContinuous nonvalved filtering facepiece respirator use for 4 hours was not associated with clinician impairment in blood gas and peripheral SpO₂ levels during nonexertional clinical ED work.
