About this study
Official title: Effects of Different Desktop Materials on Thermal Comfort and Attention
The aim of this study is to test the suitability of different types of desk surfaces. The investigators will test 10 different surfaces (oak-ruff, oak-varnished, oak-oiled, spruce-ruff, spruce-varnished, spruce-oiled, particleboard laminate, particleboard veneer, corian and glass). Firstly, the investigators will perform tests to assess physical characteristics of the materials (thermal conductivity, hardness, roughness, skid measures). Secondly, the investigators will measure the participants' forearm skin temperature after 20-minutes of using each desk surface. During those 20 minutes the participants will solve an attention test.
Read the detailed description
People are surrounded by objects that are made of different materials. These materials should be carefully chosen, especially the ones that are in direct contact with user's skin. Office workers are constantly in contact with desk surface (while reading, typing, filling in forms, etc.). Therefore, it is important that the material of desk surface is suitable and properly chosen. It should be both functional and aesthetic. The aim of this study is to evaluate the suitability of different desk surfaces for sedentary workers. The investigators will test 10 different surfaces (oak-ruff, oak-varnished, oak-oiled, spruce-ruff, spruce-varnished, spruce-oiled, particleboard laminate, particleboard veneer, corian and glass). All surfaces will be square shaped (800x800 mm). Firstly, the investigators will perform tests to assess physical characteristics of the materials (thermal conductivity, hardness, roughness, skid measures). Secondly, the investigators will measure the participants' forearm skin temperature after 20-minutes of desk use. Every participant will test all 10 sample desk surfaces (cross-over design). The investigators will use thermal IR camera to measure the temperature of participant's skin surface. The investigators will measure the temperature before and after the contact with desk surface. During those 20 minutes the participant will solve an attention test to assess the impact of different materials on attention. At the end, the participants will answer a questionnaire about the suitability of the material.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Desk surfaceOther
The participants will test all 10 desk surfaces and will be randomly allocated to one of the desks each time.
What is being measured
The primary outcome is the main question the study is designed to answer.
Change of the skin temperature measured on forearm
Skin temperature in the forearm will be measured with Infrared thermal camera. Thermal camera is suitable for the measurements since it is a reliable tool for measuring skin temperature. The temperature is presented in Celsius degrees. Moreover, thermal camera provides a thermal picture indicating temperature distribution in the space.
Measured: at the beginning and after 20 minutes of using desk surface
Secondary outcomes (2)
Attention test
The attention test will be performed on computer. On the computer screen letters P and R will appear. Each time the letter R appears the participant will have to click ''space''. If a letter P appears the participant should not react.
Measured: 180 seconds
Adjusted Mood and feelings questionnaire
The questionnaire consists of two questions. One is asking the participant about their current mood. The second question is asking the participant about their current arousal. The participant answers both questions using a 9-level scale (1 meaning not at all and 9 meaning very much). There is no total value of the questionnaire. Also, higher or lower values do not represent better or worse outcome.
Measured: 180 seconds

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of this study is to test the suitability of different types of desk surfaces. The investigators will test 10 different surfaces (oak-ruff, oak-varnished, oak-oiled, spruce-ruff, spruce-varnished, spruce-oiled, particleboard laminate, particleboard veneer, corian and glass). Firstly, the investigators will perform tests to assess physical characteristics of the materials (thermal conductivity, hardness, roughness, skid measures). Secondly, the investigators will measure the participants' forearm skin temperature after 20-minutes of using each desk surface. During those 20 minutes the participants will solve an attention test.

Where is the study taking place?
The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change of the skin temperature measured on forearm (time frame: at the beginning and after 20 minutes of using desk surface). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Oct 2019.
