Assessment of work-related stress utilizing the Find My Stress mobile application among university students and adult workers amidst the COVID-19 pandemic.

OBJECTIVES: This cross-sectional study aimed to evaluate work-related stress and the efficacy associated with the newly developed Find My Stress mobile application. The global impact of the COVID-19 pandemic has significantly influenced the quality of life, transcending geographical boundaries and inducing stress that has detrimentally affected health and work efficiency. METHODS: A total of 440 male and female participants, comprising university students and adult workers, were enrolled in the study. Participants completed an assessment in the application that consisted of three components: 1) perceived work stress, 2) environmental stress factors, and 3) application efficiency. RESULTS: University students exhibited higher perceived stress levels compared to adult workers (p = 0.031). The predominant physical factors contributing to musculoskeletal disorders in university students were identified as movement and posture factors, particularly related to vibration and organization. Conversely, environmental factors took precedence in adult workers, followed by posture and movement. The reliability of the perceived work stress questionnaire was evaluated by Cronbach's alpha coefficient and yielded a value of 0.96. The Find My Stress application demonstrated high efficiency. CONCLUSIONS: Elevated levels of work stress were observed in both university students and adult workers. Initial signs of musculoskeletal disorders in university students primarily manifested in the neck and upper back, arms, and hands, while adult workers predominantly reported complaints related to the arms and hands. The Find My Stress application emerges as a valuable tool for screening occupational stressors.

Assessing the physiological strain of physical therapists according to work experience: A cross-sectional study.

OBJECTIVES: This cross-sectional study aimed to assess the physiological response of physical therapists to compare the physiological workload within three groups of varying work experience and their comparative physiological responses during a 15-min recovery period. METHODS: Thirty therapists participated in the present study. They were divided into three groups with varying levels of work experience based on the number of years they had been in active employment: 1) Early Career (EC) group = 2-6 years); 2) Mid-Career (MC) group = 7-11 years), and 3) Late career (LC) group = over 11 years). Each group included 10 subjects comprised of both males and females. To conduct the measurements, each therapist treated one hemiplegic patient for 20 min using a passive range of motion protocol and then rested for 15 min. The maximum voluntary contraction on trapezius and deltoid muscles were tested using electromyography before and after treatment. During treatment, the muscle workload, muscle fatigue, and cardiovascular load were measured. The perceived workload was assessed using a subjective workload index (SWI) questionnaire following treatment. RESULTS: The three work experience groups of physical therapists performed a similar workload. The SWI corresponded well with physiological measurement. The muscle capacity after treatment of the EC group was significantly lower than that of the MC group (p < 0.05). Notably, the right deltoid of the LC group was significantly lower than that of the MC group. CONCLUSIONS: The physical therapists worked with a moderate, objectified workload. A 15-min rest period brought the cardiovascular load below 30% and lowered fatigue in the right deltoids. This result may indicate a musculoskeletal disorder warning signal for the physical therapists.

Thai traditional massage: efficiency-assessment of three traditional massage methods on office workers: an explorative study.

Thai Traditional Massage (TTM) is popular and widely spread in Thailand. This project is aimed at studying the physiological efficiency of three popular TTM methods based on acupressure Meridian basal lines: the Sen Sib(SS) ten lines, Ratchsamnak (RS), Royal style; and Chaloeysak (CS), Folk style. Thirty healthy female administrative employees participated as patients. All were treated for 30 min with the 3 types of massage with a two-week interval between each treatment. Muscle strain was objectified by measuring strength and endurance with surface electromyography of muscle put under stress during office work: the M. Trapezius (static postural load) and the wrist muscles (M. flexors & extensors Carpi-Radialis) (dynamic contractions) as well as measuring the subjective Visual Analogue Scale (VAS) before and after the sessions. An ANOVA-statistical analysis showed that strength in shoulders was not significantly different, but some forearm fatigue was decreased significantly among the three massage techniques.

Musculoskeletal disorders: a new approach.

Musculoskeletal disorders are still a major problem in daily occupational life. Despite the high incidence rates and important consequences for employees, employers and society, efficient preventive strategies seem to fail in efficiency. The reason may be found in approaching the issue via the classic post-factum analysis. The preventive measures are almost not implemented because of the low predictability to be injured which affects the awareness of the problem and the low identification with the improvement proposals. MSD belong to the cumulative diseases which require and anticipating strategy based on early detection of pre-indicating symptoms.

Cardiorespiratory capacity of Thai workers in different age and job categories.

The objective of this study was to assess the cardiorespiratory capacity of Thai male and female blue-collar workers in different age and occupational categories. The maximal oxygen uptake (VO2max) of 70 men and 56 women was assessed using a submaximal bicycle-ergometer test supplemented with ventilatory gas analyses. The age of the subjects varied from 16 to 55 years. They worked in construction, manual materials handling and metal jobs. For the male subjects the VO2 max ranged from 1.43 to 3.50 l/min and from 21.3 to 66.3 ml/min/kg. The corresponding values for the female subjects were 0.97-2.97 l/min and 16.2-42.4 ml/min/kg. According to the European fitness classifications the mean age related VO2max of the male and female subjects can be considered moderate or poor. When compared to the European data heart rate of the subjects was 25-30% higher at submaximal levels of oxygen uptake, confirming earlier results. The low cardiorespiratory capacity of many Thai workers may be a limiting or even risk factor in physically demanding jobs.

Ergonomics in practice: physical workload and heat stress in Thailand.

This study consists of assessments of the thermal environment and physiological strain in tasks associated with airport, construction, and metal jobs. The number of male and female participants was 108. Environmental heat stress was evaluated with the WBGT index. Physiological strain was evaluated by the relative cardiovascular load (%CVL) based on the measurements of heart rate. Also the increase of body temperature, weight loss, and perceived discomfort were determinated. At work sites the assessments lasted for 2 to 4 hrs for each participant. The mean physiological strain exceeded the level of 30%CVL. Severe peaks (over 60% CVL) were observed in specific tasks being in agreement with perceived discomfort ratings. The increase of body temperature and weight loss in most cases remained within acceptable limits. For the most strenuous tasks, various ergonomic improvements were developed in consultation with workers and managers.

Evaluation of a step-test for assessing the cardiorespiratory capacity of workers in Thailand: a pilot study.

The aim of this pilot study was to evaluate the accuracy of a simple step-test procedure supplemented by the measurement of heart rate (HR) (STEP1) to assess the cardiorespiratory capacity i.e., maximal oxygen consumption (VO2max) of Thai workers. The subjects comprised 18 men and 17 women. Their ages varied from 19 to 20 years and all were physically active. The subjects performed three tests: a submaximal incremental cycle-ergometer (CYCLE) test supplemented by HR recordings and respiratory gas exchange, and two step-tests (STEP1 and STEP2). In the STEP1 test HR was recorded continuously. The STEP2 test included the measurements of HR and respiratory gas exchange. For the male subjects the mean difference of the estimated VO2 max values obtained from the CYCLE and STEP1 test was 15% (p < 0.05). With the female subjects the mean VO2 max values were equal when predicted according to the CYCLE and STEP1 tests. The present STEP1 test is not sufficiently accurate to predict the VO2 max of Thai men. The results of this pilot study need to be confirmed with larger samples of subjects with various backgrounds in terms of individual characteristics and occupations.
