Summary
# Editorial Summary: Hospitalisation and Disease Severity Alter the Resting Pattern of Horses Just as hospitalisation disrupts sleep patterns in human patients, equine recovery may be similarly compromised by altered rest behaviour during veterinary care. Oliveira and colleagues observed eight hospitalised horses with varying degrees of metacarpophalangeal osteoarthritis over their first five days in-house, using continuous video monitoring to quantify lateral recumbency, sternal recumbency, and frequency of lying episodes. Horses demonstrated significant behavioural adaptation, with lateral recumbency and recumbency frequency increasing markedly after day 4 (P<0.05) and sternal recumbency increasing after day 3 (P<0.05), suggesting they required an acclimatisation period before resuming near-normal rest patterns. Critically, disease severity substantially influenced these changes: mildly affected horses increased recumbency time to spare their damaged limbs, whilst severely osteoarthritic individuals showed reduced recumbency frequency and duration, likely due to the biomechanical difficulty of transitioning between standing and lying positions with severely compromised joint function. For equine practitioners, these findings highlight that hospitalised horses—particularly those with advanced orthopaedic disease—may experience sleep deprivation that could impair healing; tailoring management strategies to facilitate comfortable recumbency transitions and providing supportive environments may become critical components of recovery protocols.

Practical Takeaways
- •Hospitalised horses show progressive adaptation in resting behaviour over the first 5 days; expect increased lying behaviour after day 3-4 as horses acclimate to the environment
- •Disease severity significantly impacts rest quality; severe osteoarthritis cases may struggle with recumbency transitions and require environmental modifications (padded stalls, minimal obstacles) to facilitate safe lying
- •Monitor recumbency patterns in hospitalised horses with joint disease as a welfare indicator—reduced lying in severe cases may indicate pain or difficulty and warrants intervention to support adequate rest
Key Findings
- •Total lateral recumbency time and recumbency frequency increased significantly after day 4 of hospitalisation (P<0.05)
- •Total sternal recumbency time increased significantly after day 3 of hospitalisation (P<0.05)
- •Horses with mild osteoarthritis spent more time in recumbency on day 5, sparing the affected limb
- •Horses with severe osteoarthritis showed decreased recumbency frequency and duration, suggesting potential sleep deprivation due to joint flexion difficulty
