RESUMO

The analgesic effect of cryotherapy in an induced lameness model was evaluated. Lameness was induced with solar pressure from a custom-made shoe in a 10-horse, cross-over study. The degree of lameness was recorded with a commercial non-invasive inertial sensor. The distal limbs were maintained in an ice and water slurry (cryotherapy) or at ambient temperature (control) for 1 hour. Lameness was assessed serially over the following hour. Lameness at each time point was compared to the baseline induced lameness, within and between groups. Lameness had improved significantly in all horses 5 minutes after treatment but remained improved 10 minutes after treatment for the cryotherapy group only. Fifteen minutes after treatment, lameness in the cryotherapy group was improved relative to the control. Cryotherapy produced moderate, transient analgesia. Additional research is required to determine if altering the method, duration, or temperature of cryotherapy, as well as the targeted pathology and anatomy, alters the analgesic effect.


La cryothérapie fournit une analgésie transitoire dans un modèle de boiterie induite chez le cheval. L'effet analgésique de la cryothérapie dans un modèle de boiterie induite a été évalué. La boiterie a été induite par une pression sur la sole à l'aide d'un fer sur mesure dans une étude croisée de 10 chevaux. Le degré de boiterie a été enregistré avec un capteur inertiel non invasif du commerce. Les membres distaux ont été maintenus dans une bouillie de glace et d'eau (cryothérapie) ou à température ambiante (témoin) pendant 1 heure. La boiterie a été évaluée en série au cours de l'heure suivante. La boiterie à chaque moment a été comparée à la boiterie induite au départ, au sein et entre les groupes. La boiterie s'était améliorée de manière significative chez tous les chevaux 5 minutes après le traitement mais restait améliorée 10 minutes après le traitement pour le groupe cryothérapie uniquement. Quinze minutes après le traitement, la boiterie dans le groupe cryothérapie était améliorée par rapport au témoin. La cryothérapie a produit une analgésie modérée et transitoire. Des recherches supplémentaires sont nécessaires pour déterminer si la modification de la méthode, de la durée ou de la température de la cryothérapie, ainsi que la pathologie et l'anatomie ciblées, modifient l'effet analgésique.(Traduit par Dr Serge Messier).

RESUMO

Lyme disease is usually associated with forested habitats but has recently emerged on treeless islands in the Western Isles of Scotland. The environmental and human components of Lyme disease risk in open habitats remain unknown. We quantified the environmental hazard and risk factors for human tick bite exposure among treeless islands with low and high Lyme disease incidence in the Western Isles. We found a higher prevalence of Borrelia burgdorferi sensu lato-infected ticks on high-incidence than on low-incidence islands (6.4% vs. 0.7%); we also found that residents of high-incidence islands reported increased tick bite exposure. Most tick bites (72.7%) occurred <1 km from the home, including many in home gardens. Residents of high Lyme disease incidence islands reported increasing problems with ticks; many suggested changing deer distribution as a potential driver. We highlight the benefits of an integrated approach in understanding the factors that contribute to Lyme disease emergence.
