About this study
Official title: Investigation of Respiratory System, Musculoskeletal System, Physical Activity Level and Quality of Life in Different Types of Office Workers.
There are no studies in the literature reporting the posture, chest mobility, dyspnea, flexibility, quality of life and physical activity levels of emergency call center employees. The aims of this observational study are; 1) to evaluate posture, chest mobility, strength, dyspnea, flexibility, musculoskeletal disorders, physical activity and quality of life in emergency call center workers and office workers, 2) to reveal the relationships between these parameters of both research groups and 3) The aim is to compare these measurement parameters in emergency call center workers and office workers.
Read the detailed description
Over time, there has been an increase in the number of office workers and the use of computers. Working in a static position for long working hours and improper working postures can lead to loss of flexibility in the muscles, decrease in thoracic mobility, pain in the musculoskeletal system and deterioration of ideal posture. Emergency call center employees work long hours, in shifts that require serious attention, where stress is intense and the circadian rhythm is disrupted. There is no study in the literature that evaluates the posture, chest mobility, dyspnea, flexibility and physical activity levels of emergency call center employees. Therefore, the aim of our study is; It is a comparative evaluation of posture, chest mobility, cough strength, dyspnea flexibility, musculoskeletal disorders, physical activity level and quality of life in emergency call center operators and desk workers.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Physical Evaluations of individualsOther
Participants will be evaluated on posture, chest mobility, cough strength, flexibility, hand grip strength and pinch strength. They will be asked to answer the Modified Medical Research Council Scale, Cornell Musculoskeletal Disorders Questionnaire, International Physical Activity Questionnaire Short Form and Short Form -36. The data to be obtained from all these evaluations are planned to be collected face to face from the participants at once and within a maximum of 1 hour.
| Study group | Role | What they receive |
|---|---|---|
| Emergency call center workers | This group will consist of individuals working as operators at Izmir 112 Emergency Call Center. Receives: Other: Physical Evaluations of individuals | |
| Office workers | This group will consist of office workers who work actively at a desk. Receives: Other: Physical Evaluations of individuals |
What is being measured
The primary outcome is the main question the study is designed to answer.
Handgrip strength
Hand grip strength will be measured using the Jamar hand dynamometer.
Measured: up to 5 minutes
Secondary outcomes (9)
Thoracic mobility
Individuals will be asked to sit in an upright sitting position with their arms slightly open, and their chest circumference will be measured with a tape measure at three different levels (axillary, epigastric, subcostal) at rest, deep breathing (maximum inspiration) and deep exhalation (maximum expiration). The difference between measurements will be recorded in centimeters.
Measured: up to 5 minutes
Cough strength
Cough strength will be evaluated using a PEFmeter.
Measured: up to 2-3 minutes
Dyspnea
Dyspnea will be assessed using the Modified Medical Research Council (MMRC) Scale. This scale is a five-item scale based on various physical activities that cause a feeling of shortness of breath (dyspnea). As the score an individual gets from the scale increases, the perception of shortness of breath also increases.
Measured: up to 1 minute
Posture
Posture will be evaluated with sensorless posture analysis software based on the artificial intelligence concept created by Fizyosoft and Becure.
Measured: up to 5 minutes
Musculoskeletal pain
Musculoskeletal pain will be assessed using the Turkish version of the Cornell Musculoskeletal Disorders Questionnaire. The score is obtained by multiplying the weighted scores corresponding to the individual's answer. The scores obtained for each region range between 0 and 90, and higher scores indicate higher levels of pain disorder.
Measured: up to 5 minutes
Flexibility
Flexibility will be evaluated with sit-reach test, pectoral shortness tests, and shoulder adductor and internal rotator shortness tests.
Measured: up to 5 minutes
Pinch strength
Pinch strength will be evaluated using a hydraulic pinch dynamometer.
Measured: up to 5 minutes
Physical activity level
Physical activity level will be assessed using the Turkish version of the International Physical Activity Questionnaire Short Form."MET-min/week" scores were obtained by multiplying the minutes, days, and MET (which is set by convention at 3.5 milliliter of oxygen per kilogram per minute) values of each activity. According to these scores, individuals were classified as inactive, minimally active, and sufficiently active.
Measured: up to 2 minutes
Health-related quality of life
Quality of life will be assessed using the SF-36. It consists of eight subscales including physical function, role limitations due to physical health and emotional problems, vitality, emotional well-being, social function, bodily pain, and general health. Each subscale is scored between 0 (poorer health) and 100 (better health).
Measured: up to 5 minutes
