Transversus Abdominis Muscle

Background: Core muscle activation is an effective intervention for the management of Low Back Pain (LBP). This study developed new feedback for detecting activation of the transversus abdominis muscle in the lumbar spine. The purpose of this study was to examine the validity and reliability of the feedback device for transversus abdominis muscle contraction. Methods: The participants in this study were 20 healthy males and females (aged 24.1 ± 6.8 years). The feedback sensor was attached to the lumbar support at the front of the trunk. The participants performed an abdominal drawing-in maneuver in order to activate the transversus abdominis muscle, and values from the feedback sensor were collected at the same time. Ultrasound imaging of the transversus abdominis muscle was also collected simultaneously. The feedback sensor collected values at different clinical levels of the pressure biofeedback unit at 64, 66, 68, and 70 mmHg. The protocol was repeated with a 24-hr interval. Intra-class correlation coefficient, coefficient of variation and standard error of measurements were used to examine reliability. The validity of the values obtained from the relationship between the feedback sensor and transversus abdominis muscle thickness was analyzed using Pearson’s correlation coefficients. Results: Test–retest reliability of the feedback sensor was excellent (ICC = 0.946, CV = 2.6%, SEMs = 0.54%). Values of the feedback sensor reported a significantly moderate correlation with the gold standard ultrasound measurement (r = - 0.514, p < 0.001). Conclusion: The feedback device demonstrated potential reliability and validity for clinical use by indicating activation of the transversus abdominis muscle.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P &lt; 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Rehabilitative ultrasound imaging (RUSI) technique seems to be a valid and reliable tool for diagnosis and treatment in physiotherapy and has been widely studied in the lumbopelvic region the last three decades. The aims for this utility in clinical settings must be review through a systematic review, meta-analysis and meta-regression. A systematic review was designed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines with PROSPERO registration and per review in all phases of the process using COVIDENCE, analysis of risk of bias and meta-analysis using REVMAN, and meta-regression calculation using STATA. Database screening provided 6544 references, out of which 321 reported narrative synthesis, and 21 reported quantitative synthesis, while only 7 of them provided comparable data to meta-analyze the variables pain and muscle thickness. In most cases, the forest plots showed considerable I2 heterogeneity indexes for multifidus muscle thickness (I2 = 95%), low back pain (I2 = 92%) and abdominal pain (I2 = 95%), not important for transversus abdominis muscle thickness (I2 = 22%), significant heterogenity (I2 = 69%) depending on the subgroup and not important internal oblique muscle thickness (I2 = 0%) and external oblique muscle thickness (I2 = 0%). Meta-regression did not provide significant data for the correlations between the variables analyzed and the intervention, age, and BMI (Body Mass Index). This review reveals that RUSI could contribute to a high reliability of the measurements in the lumbopelvic region with validity and reliability for the assessments, as well as showing promising results for diagnosis and intervention assessment in physiotherapy compared to the traditional model, allowing for future lines of research in this area.

The current research aims to evaluate the reliability and validity of the Hindi Child Perception Questionnaire (CPQ11–14) in a child population of India. A randomly selected sample of children aged 11–14 years (n = 331) and their parents completed the Hindi translation of CPQ11–14 and the Parental-Caregiver Perceptions Questionnaire (P-CPQ), respectively, in this cross-sectional study. Children also provided a self-rating of oral health and were examined for dental caries. Exploratory Factor Analysis (EFA) was conducted to assess the dimensionality of the Hindi-CPQ11–14. Internal consistency and reliability on repeated administration were evaluated. Convergent and divergent validities were determined by estimating correlation coefficients between items and the hypothesised subscales. Concurrent validity was assessed using multiple linear regression analyses. The four factors extracted in EFA had a total variance of 38.5%, comprising 31 items. Cronbach’s alpha for the internal consistency of the overall scale was 0.90; reliability on repeated administration was 0.92. All the Hindi CPQ11–14 items had an item-hypothesised subscale correlation coefficient of ≥0.4, and these were greater than item-other hypothesised subscale correlations, demonstrating good convergent and divergent validities respectively. Hindi-CPQ11–14 was associated with self-ratings of the oral health and overall P-CPQ scores demonstrating good concurrent validity. Hindi-CPQ11–14 showed a factor structure different from the English CPQ11–14 and exhibited good validity and reliability.

Activity Questionnaire

The goal of this study was to develop a Korean version of the Global Physical Activity Questionnaire (K-GPAQ) and to examine its reliability and validity. The English version of the GPAQ was translated to the Korean language (K-GPAQ) via forward–backward translation. Reliability of the K-GPAQ was evaluated using a one-week interval test–retest method with 115 individuals. Criterion-related validity of the K-GPAQ was examined with 199 participants using accelerometers. Cohen’s kappa and Spearman’s correlation coefficients were used to measure test–retest reliability and validity, respectively. A Bland–Altman analysis was used to assess agreement between physical activity (PA) levels measured via K-GPAQ and the accelerometer. Coefficients for the reliability of the K-GPAQ showed moderate agreement for recreational PA and slight agreement for work-related PA (Cohen’s kappa: 0.60–0.67 for recreational PA and 0.30–0.38 for work-related PA and Spearman’s rho: 0.27–0.47 for work-related PA and 0.53–0.70 for recreational PA). Criterion validity of the total amount of PA, as measured by the K-GPAQ and the accelerometer, showed a weak but significant correlation ( r = 0.34, p < 0.01). The K-GPAQ is a reliable and valid questionnaire to measure PA although K-GPAQ overestimated PA levels.

In this study a Chinese version of the Situational Self-Awareness Scale (SSAS; Govern & Marsch, 2001) was developed and tested for validity and reliability. Participants were 1,244 undergraduate students. Exploratory and confirmatory factor analysis and other statistical methods yielded results indicating a good correlation of items in the Chinese (C-SSAS) and English version of the scale. When private self-awareness was assessed in a private setting the score of participants was significantly greater and likewise the public self-awareness scores were higher when the scale was completed in a public setting. Test-retest reliability was significant across situations and time. The reallocation of one item to public self-awareness in the C-SSAS from private in the SSAS was indicative of differences between Eastern and Western cultures and this is discussed. In general, the results indicated that the Chinese version of the SSAS has good reliability and validity. The scale should, therefore, be suitable as a reference to develop scales for evaluating personnel working in specific occupations.

Abstract Background and Purpose. The purpose of this study was to examine the reliability and validity of data obtained with 2 newly developed shuttle run tests (SRT-I and SRT-II) to measure aerobic power in children with cerebral palsy (CP) who were classified at level I or II on the Gross Motor Function Classification System (GMFCS). The SRT-I was developed for children at GMFCS level I, and the SRT-II was developed for children at GMFCS level II. Subjects. Twenty-five children and adolescents with CP (10 female, 15 male; mean age=11.9 years, SD=2.9), classified at GMFCS level I (n=14) or level II (n=11), participated in the study. Methods. To assess test-retest reliability of data for the 10-m shuttle run tests, the subjects performed the same test within 2 weeks. To examine validity, the shuttle run tests were compared with a GMFCS level–based treadmill test designed to measure peak oxygen uptake. Results. Statistical analyses revealed test-retest reliability for exercise time (number of levels completed) (intraclass correlation coefficients of .97 for the SRT-I and .99 for the SRT-II) and reliability for peak heart rate attained during the final level (intraclass correlation coefficients of .87 for the SRT-I and .94 for the SRT-II). High correlations were found for the relationship between data for both shuttle run tests and data for the treadmill test (r=.96 for both). Discussion and Conclusion. The results suggest that both 10-m shuttle run tests yield reliable and valid data. Moreover, the shuttle run tests have advantages over a treadmill test for children with CP who are able to walk and run (GMFCS level I or II). [Verschuren O, Takken T, Ketelaar M, et al.

Force Data

The assessment of loading during walking and running has historically been limited to data collection in laboratory settings or with devices that require a computer connection. This study aims to determine if the loadsol®—a single sensor wireless insole—is a valid and reliable method of assessing force. Thirty (17 male and 13 female) recreationally active individuals were recruited for a two visit study where they walked (1.3 m/s) and ran (3.0 and 3.5 m/s) at a 0%, 10% incline, and 10% decline, with the visits approximately one week apart. Ground reaction force data was collected on an instrumented treadmill (1440 Hz) and with the loadsol® (100 Hz). Ten individuals completed the day 1 protocol with a newer 200 Hz loadsol®. Intraclass correlation coefficients (ICC3,k) were used to assess validity and reliability and Bland–Altman plots were generated to better understand loadsol® validity. Across conditions, the peak force ICCs ranged from 0.78 to 0.97, which increased to 0.84–0.99 with the 200 Hz insoles. Similarly, the loading rate ICCs improved from 0.61 to 0.97 to 0.80–0.96 and impulse improved from 0.61 to 0.97 to 0.90–0.97. The 200 Hz insoles may be needed for loading rate and impulse in running. For both walking and running, the loadsol® has excellent between-day reliability (>0.76).
