Plain English summary of protocol
Background and study aims
Prolonged use of tablets causes a reduction in movement which can lead to musculoskeletal disorders. This study aims to evaluate the effect of different tablet tilt positions on muscle and breathing function.
Who can participate?
Undergraduate student aged 18 - 25 years who use a tablet for more than 2 hours per day for the past 6 months.
What does the study involve?
Participants perform a writing task for 2 hours. Group 1 position their tablets at a tilt of 0 degrees, and group 2 use a tablet tilt position of 40 to 55 degrees.
What are the possible benefits and risks of participating?
None
Where is the study run from?
Burapha University (Thailand)
When is the study starting and how long is it expected to run for?
January 2021 to June 2021

Scientific title | Effect of tablet tilt positioning on ergonomic risks and respiratory function |
Study objectives | 0-degree tablet placement on a flat surface of a student chair affects ergonomic risks and respiratory function when compared with 40- to 55-degree tablet placement. |
Ethics approval(s) | Approved 04/04/2021, Research and Innovation Administration Division, Burapha University (Chonburi, Thailand; +66 (0)38-102561-62; research@buu.ac.th), ref: HS004/2564 |
Health condition(s) or problem(s) studied | Prevention of poor posture in students |
Intervention | A total of 18 undergraduate student participants are divided into two groups of 9 persons per group using the sealed envelope method. Group 1 position their tablets at a tilt of 0 degrees, and group 2 use a tablet tilt position of 40 to 55 degrees. Participants perform the same writing task for 2 hours in the same environment with identical temperature, light, and chair. The researchers collected data on the rapid upper-limb assessment (RULA), respiratory function, and costovertebral (CV) angle before and after the study. They used a standard student chair, a tablet with a tilting tool, a spirometer (CareFusion MicroLab), and a CV angle assessment tool for the evaluation. |
Intervention type | Behavioural |
Primary outcome measure | Upper limb function measured using rapid upper-limb assessment (RULA) at baseline and 2 hours after tablet use |
Secondary outcome measures | Respiratory function measured using spirometer at baseline and 2 hours after tablet use: 1.1. Forced expiratory volume in 1 second (FEV1) 1.2. Forced vital capacity (FVC) |
