Puagprakong P., Earde P., Kooncumchoo P.,"Lumbo-Pelvic-Hip Angle Changes During Upright and Free Style Sitting in Office Workers with Lower Crossed Syndrome.", Apr. 2021, p. 532-538.
Lower crossed syndrome (LCS) is an imbalance of muscles in the lower body segment. Muscle imbalance with prolonged sitting may increase the risk of low back pain. The objective of this study was to study the lumbo-pelvic-hip angle in upright and freestyle sitting in healthy and LCS individuals. Thirty office workers (normal = 10, LCS type A = 10, and LCS type B = 10) who worked 6–8 h./d in a sitting posture were recruited. Lumbo-pelvic-hip angle was recorded while participants typed a text for 30 min in upright and freestyle sitting. Two-ways mixed model ANOVA and post-hoc Turkey test were used to analyze data. Decreased lumbar lordosis was found among the three groups. However the LCS type A group maintained their lumbar lordosis and anterior pelvic tilt, while lumbar kyphosis and posterior pelvic tilt were found in LCS type B in both sittings.
Mamom, J., Rungreungduayboon,B, "A Multidisciplinary Integrative Innovative Mattress Design to Prevent Pressure Injury for Palliative Care in the Community in Thailand", Vol. 48(4), Apr 2021, P 76-81.
A pressure injury is a severe complication that causes excessive interface pressure on a bony prominence and usually occurs in palliative patients in the community. The article describes a new healthcare innovation, A lateral tilting mattress (LTM), based on the pressure injury pathophysiology principle. This modern nursing innovation, created by a multidisciplinary team that could adjust a patient's head and knee and rotate to the left and right, may decrease interface pressure over bony prominences in palliative patients. This experimental research design of 70 palliative home-based patients examined the effectiveness of LTM on pressure injury healing scores and family caregiver's quality of life levels over time from September 2019 to May 2020. We examined differences in patients' pressure injury healing scores and family caregivers' quality of life levels between the different groups: LTM versus no-LTM. Significant time by group interactions was found on patients' pressure injury healing (F = 235.123, p <.01) and family caregivers' quality of life (p <.05) in the LTM versus no LTM group. The results provide evidence for the effectiveness of LTM in improving pressure injury healing scores that may decrease interface pressure over bony prominences in palliative patients and the overall quality of life levels in family caregivers. The findings also suggest the need for further healthcare innovation to improve the quality of care for palliative patients, increase the quality of life (or decrease stress level) among family caregivers, and reduce workloads and danger for caregivers.

The physical fitness of the elderly is more likely to deteriorate by aging. Balance and coordination exercise are important to maintain the strength of the musculoskeletal system, joints, and bones as well as to reduce the risk of falling. This study presents the development of a low-cost force plate with software application (Stand Balance) for analyzing balance and coordination training for the elderly. The structure of the force plate consists of load cell circuits connected with Node32s board as part of a signal measurement that sends wireless data via Bluetooth to analyze with LabView. The software application records real-time and displays data such as the patient’s weight and training information that could be sent to the healthcare provider who can analyze the patient’s information. The software has been designed in 4 operating modes (Balance Screening, Exercise, Games, and CoP Modes). The purpose of this study was to test whether the Stand Balance could detect Center of Pressure (CoP) and Ground Reaction Forces (GRFs) and display the results regarding its accuracy and repeatability. This research found that the error of static weight measurement is 4.84%, which is assumed to be an acceptable measure of the GRFs (especially when the human body is contact to the developed force plate). Moreover, the absolute error of CoP-accuracy of (Top Middle, Top Right, Middle Left, Center, Middle Right, Bottom Left, Bottom Middle, and Bottom Right) study areas are 5.14, 4.08, 5.44, 5.02, 5.88, 7.25, 4.49, 5.28, and 6.47 mm, respectively and the error of CoP-repeatability of study areas are 0.82, 0.74, 1.21, 0.95, 1.34, 0.89, 0.74, 1.13, and 1.18%, respectively. The absolute errors of CoP-accuracy are very close to 0 mm and the error of CoP-repeatability are less than 1.5%, which show high accuracy and precision that adequate for Stand Balance to assess balance and train coordination. It could ensure that the Stand Balance could detect CoP and GRFs effectively and, therefore, can be used as a device for further clinical implementation with human.
