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 < 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.

Objective. To provide empirical justification for selecting motor scales for stroke patients, the authors compared the psychometric properties (validity, responsiveness, test-retest reliability, and smallest real difference [SRD]) of the Fugl-Meyer Motor Scale (FM), the simplified FM (S-FM), the Stroke Rehabilitation Assessment of Movement instrument (STREAM), and the simplified STREAM (S-STREAM). Methods. For the validity and responsiveness study, 50 inpatients were assessed with the FM and the STREAM at admission and discharge to a rehabilitation department. The scores of the S-FM and the S-STREAM were retrieved from their corresponding scales. For the test-retest reliability study, a therapist administered both scales on a different sample of 60 chronic patients on 2 occasions. Results. Only the S-STREAM had no notable floor or ceiling effects at admission and discharge. The 4 motor scales had good concurrent validity (rho ≥ .91) and satisfactory predictive validity (rho = .72-.77). The scales showed responsiveness (effect size d ≥ 0.34; standardized response mean ≥ 0.95; P < .0001), with the S-STREAM most responsive. The test-retest agreements of the scales were excellent (intraclass correlation coefficients ≥ .96). The SRD of the 4 scales was 10% of their corresponding highest score, indicating acceptable level of measurement error. The upper extremity and the lower extremity subscales of the 4 showed similar results. Conclusions. The 4 motor scales showed acceptable levels of reliability, validity, and responsiveness in stroke patients. The S-STREAM is recommended because it is short, responsive to change, and able to discriminate patients with severe or mild stroke.

Introduction Research investigating psychometric properties of multi-joint upper body strength assessment tools for older adults is limited. This study aimed to assess the test–retest reliability and concurrent validity of novel clinical strength measures assessing functional concentric and eccentric pushing activities compared to other more traditional upper limb strength measures. Methods Seventeen participants (6 males and 11 females; 71 ± 10 years) were tested two days apart, performing three maximal repetitions of the novel measurements: vertical push-off test and dynamometer-controlled concentric and eccentric single-arm press. Three maximal repetitions of hand-grip dynamometry and isometric hand-held dynamometry for shoulder flexion, shoulder abduction and elbow extension were also collected. Results For all measures, strong test–retest reliability was shown (all ICC > 0.90, p < 0.001), root-mean-squared coefficient of variation percentage: 5–13.6%; standard error of mean: 0.17–1.15 Kg; and minimal detectable change (90%): 2.1–9.9. There were good to high significant correlations between the novel and traditional strength measures (all r > 0.8, p < 0.001). Discussion The push-off test and dynamometer-controlled concentric and eccentric single-arm press are reliable and valid strength measures feasible for testing multi-joint functional upper limb strength assessment in older adults. Higher precision error compared to traditional uni-planar measures warrants caution when completing comparative clinical assessments over time.

Abstract Introduction: A proper assessment of gait pattern is a significant aspect in planning the process of teaching gait in hemiparetic post-stroke patients. The Wisconsin Gait Scale (WGS) is an observational tool for assessing post-stroke patients’ gait. The aim of the study was to assess test-retest reliability and internal consistency of the WGS and examine correlations between gait assessment made with the WGS and gait speed, Brunnström scale, Ashworth’s scale and the Barthel Index. Material and methods: The research included 36 post-stroke patients. The patients’ gait was assessed with the use of the Wisconsin Gait Scale, gait speed with the use of walk test, the level of motor control in a paretic lower limb – according to Brunnström recovery stages, muscle tone in a paretic lower limb – according to modified Ashworth’s scale and functional independence was assessed using the Barthel Index. Gait was assessed with the use of the WGS twice, with a 7-day interval, by three experienced physiotherapists. Results: The analysis of internal consistency of the WGS revealed that the Cronbach’s α coefficient was high in the case of all the three raters and ranged from 0.85 to 0.88. It was noted that the coefficient of variation for all the comparisons was below 10%. When assessing the repeatability of the results, it was revealed that correlations between both measurements made by particular raters were very strong and highly significant. The WGS results significantly correlated with Brunnström scale, Ashworth’s scale and gait speed. Conclusions: It was concluded that the WGS has a high internal consistency and test-retest reliability. Also, significant correlations were found between gait assessment made with the use of the WGS and gait speed, level of motor control and muscle tone of a paretic lower limb. The WGS constitutes a promising tool for a qualitative, observational analysis of gait in post-stroke patients and allows for proper planning, monitoring and assessing rehabilitation results.

Purpose:To examine the concurrent validity and absolute and relative reliabilities of a commando-specific power test.Participants:21 antiterrorism commandos.Methods:All participants were assessed on a 5-m rope-climbing test (RCT) and the following tests: pull-ups, push-ups, estimated-1-repetition-maximum (est-1RM), medicine-ball put, and handgrip-strength test. The stopwatch method related to the execution time (ET) was validated by comparison with video motion analysis. The best individual attempt of 3 trials was kept for analysis, and the performance was expressed in absolute power output (APO) and body-mass relative power output (RPO).Results:Stopwatch assessment had an excellent criterion validity (r = .99, P < .001), intraclass correlation coefficient (ICC3,1) of .98, standard errors of measurement (SEM%) of 1.19%, bias ± the 95% limits of agreement of 0.03 ± 0.26 s, and minimal detectable change (MDC95) of 0.51 s. The ET, APO, and RPO were significantly correlated (P < .05) with all cited tests (absolute-value r range .55−.98), while est-1RM was not significantly correlated with the other tests. Test-retest reliability coefficients were excellent for ET, APO, and RPO (ICC3,1 > .90). The SEM% values for the ET, APO, and RPO were all under 5% (range 3.73−4.52%), all being smaller than the corresponding smallest worthwhile change. The coefficients of variation for the ET, APO, and RPO were all under 10%. %MDC95 ranged from 10.37% to 12.53%.Conclusions:Considering the strong concurrent validity and excellent test–retest reliability, the RCT is simple to administer, has ecological validity, and is a valid specific field test of upper-body power for commandos and, in addition, can be accurately assessed with a stopwatch.

Purpose: To investigate the test–retest reliability of physiological variables across four different test days and four different submaximal exercise intensities during seated upper-body poling (UBP).Methods: Thirteen abled-bodied, upper-body trained men (age 29±3years; body mass 84±12kg; height 183±5cm) performed four submaximal 4-min stages of seated UBP on four separate test days. The four submaximal stages were set at individual power outputs corresponding to a rating of perceived exertion of 9, 11, 13, and 15. The absolute reliability for pairwise test-day comparisons of the physiological variables was investigated with the smallest detectable change percentage (%SDC) and the relative reliability with the interclass correlation coefficient (ICC).Results: Absolute and relative reliability across test-day comparisons and submaximal stages were moderate to excellent for all variables investigated (V̇O2 – %SDC range: 5–13%, ICC range: 0.93–0.99; HR – %SDC range: 6–9%, ICC range: 0.91–0.97) other than blood lactate, for which absolute reliability was poor and relative reliability highly variable (%SDC range: 26–69%, ICC range: 0.44–0.92). Furthermore, absolute and relative reliability were consistent across the low-to-moderate exercise intensity spectrum and across test days.Conclusion: Absolute and relative test–retest reliability were acceptable for all investigated physiological variables but blood lactate. The consistent test–retest reliability across the exercise intensity spectrum and across test days indicates that a familiarization period to the specific exercise modality may not be necessary. For generalizability, these findings need to be confirmed in athletes with a disability by future large-scale studies.
