The study investigated the influence of ankle strength and its range of motion (ROM) on knee kinematics during drop landing. Fifteen male and fifteen female university athletes with a normal range of dynamic knee valgus (DKV) (knee frontal plane projection angle: men = 3° to 8°, females = 7° to 13°) were recruited. They performed drop landing at height 30 cm and 45 cm with three-dimensional motion capture and analysis. Knee angles were compared at specific landing phases. Isokinetic ankle strength was tested at 60°/s angular velocity while the weight-bearing lunge test was conducted to evaluate ankle ROM. For males, strength for both plantarflexors and dorsiflexors were associated with knee kinematics at both heights (30 cm: r = -0.50, p = 0.03; 45 cm: r = -0.45, p = 0.05) during maximum vertical ground reaction force (MVGRF) phase. For females, ankle invertor strength and knee kinematics were associated at both 30cm (r = 0.53; p = 0.02,) and 45 cm landing heights (r = 0.49, p = 0.03), while plantarflexor strength and knee kinematics showed a significant association during initial contact (r = 0.70, p < 0.01) and MVGRF (r = 0.55, p = 0.02) phases at height 30 cm only. Male and female athletes with normal range of DKV showed a significant relationship between ankle strength and knee kinematics at specific landing phases. These relationships varied with increased landing height.

BACKGROUND: This systematic review and meta-analysis aimed to compare the effects of high-intensity interval exercise (HIIE) with different recovery modes versus moderate-intensity continuous exercise (MICE) on cardiac troponin (cTn) elevation.
METHODOLOGY: A literature search was conducted in four databases: Scopus, PubMed, EBSCO and Web of Science from January 2010 to June 2022. The articles were screened, evaluated for quality before data were extracted. The review protocol was registered at PROSPERO (CRD42021245649). Standardized mean differences (SMD) of peak cTn were analyzed with a 95% confidence interval (95% CI) using Revman 5.4 software.
RESULTS: Six studies satisfied the inclusion criteria with a total of 92 and 79 participants for HIIE and MICE, respectively. Overall, there was no significant difference between HIIE and MICE in the elevation of cardiac troponin T (SMD: 0.41 [95% CI [-0.21, 1.03]], p = 0.20, I 2 = 77%, p for heterogeneity <0.01). In subgroup analysis, HIIE with passive recovery elicits greater release of cardiac troponin T than MICE (SMD: 0.85 [95% CI [0.44, 1.27]], p
Near-1: the evaluation of usability and task load demand of a motorized lifter for patient transfer

PURPOSE: Despite the proven benefits of motorized lifting devices in reducing the physical stresses experienced by nurses during patient transfers, the low adoption of these devices remains limited. The study aimed to assess the perceptions of nurses regarding the new motorized lifting device (NEAR-1) in terms of their perceived workload and usability during patient transfers.
MATERIALS AND METHODS: A cross-sectional study was conducted to evaluate the perceptions of nurses (n = 45) and students (n = 6) when performing patient transfers from bed to wheelchair and vice versa using the NEAR-1 compared to an existing floor lift, walking belt, and manual transfer. Participants filled out surveys evaluating the perceived task demands and usability of the NEAR-1, as well as open-ended interviews.
RESULTS: The use of the NEAR-1 significantly reduced the mean of all NASA-TLX constructs (p
Health-related quality of life amongst children with chronic kidney disease in Malaysia: performance of the Bahasa Melayu version of the PedsQL 3.0 ESRD Module : (PedsQL 3.0 VerBATIM: version in Bahasa Melayu. Translated for use in Malaysia)

BACKGROUND: The PedsQL 3.0 End Stage Renal Disease (ESRD) Module is a well-accepted instrument internationally but it is not available in the local language. We aimed to validate the Bahasa Melayu (Malay language) version and determine the health-related quality of life (HRQoL) scores amongst children with CKD in Malaysia.
METHODS: The source questionnaire in English was translated into Bahasa Melayu. Linguistic validation guidelines by the MAPI Research Institute were followed. The already validated Bahasa Melayu PedsQL 4.0 Generic Core Scales was used for comparison. Sociodemographic data were collected during the interview. Statistical analyses were performed using SPSS version 25.0.
RESULTS: Sixty-nine children aged 8 to 18 with CKD stages 4 and 5, with or without dialysis, and their caregivers were recruited. Mean age was 12.62 ± 2.77 (SD). Evaluation of the PedsQL 3.0 ESRD Module Bahasa Melayu version demonstrated good internal consistency (Cronbach alpha 0.82). There was good agreement between child self-report and parent proxy report in all domains; average intraclass correlation coefficients (ICC) were 0.78, 95% CI (0.71, 0.84). Scores obtained from Generic 4.0 scales correlated with the disease-specific ESRD 3.0 scale, Spearman's rho = 0.32, p = 0.007. The Kruskal-Wallis H test indicated that there were no significant differences between stages of CKD and their respective mean HRQoL score, χ2(2) = 2.88, p = 0.236.
CONCLUSIONS: The PedsQL 3.0 ESRD Module Bahasa Melayu version is a reliable and feasible tool for cross-cultural adaptation. A longer prospective study may help better illustrate the quality of life in this group of children.
