The aim of the study is to compare two office chairs during four different work tasks by measuring differences in muscle activities and joint angles.<\/p>\n<h3>Observation of muscle activity and body postures<\/h3>\n<p>ISKU has in collaboration with the HUMEA laboratory of the Department of Applied Physics at the University of Eastern Finland in Kuopio tested the ergonomics of office chairs. Muscle activities were measured using wireless EMG sensors from the shoulder and abdominal muscles as well as two different lower back muscles. Joint angles and upper body positions are determined in the laboratory using 3D motion analysis equipment consisting of ten cameras. In addition to the data collected by measuring devices, the analysis combines subjective feelings and observations from working in office chairs. Sixteen volunteers participated in the study.<\/p>\n<p>\u00a0<img decoding=\"async\" class=\"size-medium wp-image-27794 aligncenter\" src=\"https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-800x400.jpg\" alt=\"\" width=\"800\" height=\"400\" srcset=\"https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-800x400.jpg 800w, https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-1000x500.jpg 1000w, https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-600x300.jpg 600w, https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-768x384.jpg 768w, https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli-500x250.jpg 500w, https:\/\/isku.com\/wp-content\/uploads\/2023\/11\/T-3d-tuoli.jpg 1200w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<p style=\"text-align: center;\"><em>ISKUs Development Manager, Tuomas Mehti\u00f6, also acted as a test subject.<\/em><\/p>\n<h3>The aim of the study is to develop even better office chairs<\/h3>\n<p>ISKU has a long history of furnishing work environments and office chairs are one of the key product groups. The role of ergonomics has been further emphasized in the context of remote working.
