Contact-free radar recordings of body movement can reflect ultradian dynamics of sleep
Heglum, Hanne Siri Amdahl; Drews, Henning Johannes; Kallestad, Håvard; Vethe, Daniel; Langsrud, Knut; Sand, Trond; Engstrøm, Morten (Peer reviewed; Journal article, 2022)This work aimed to evaluate if a contact-free radar sensor can be used to observe ultradian patterns in sleep physiology, by way of a data processing tool known as Locomotor Inactivity During Sleep (LIDS). LIDS was designed ... -
Daily associations between sleep and pain in patients with chronic musculoskeletal pain
Abeler, Karin; Bergvik, Svein; Sand, Trond; Friborg, Oddgeir (Peer reviewed; Journal article, 2021)Patients with chronic pain commonly report sleep problems, and the evidence for a relationship between sleep disturbance and pain seems robust. The day‐to‐day associations between these constructs are less well studied, ... -
