A study investigated the incidence of tying-up (exertional rhabdomyolysis) in 101 horses participating in a 50-mile endurance race. Most of the horses were Arabian or half-Arabian, 75% were geldings and the average age was 11 years.
After a race, 38% of the horses had creatinine kinase (CK) levels higher than reported for resting horses. CK is an enzyme elevated due to the muscle damage associated with tying-up. However the degree of elevation was similar to that reported for normal endurance horses following a race. Elevated CK values indicative of tying-up were found in 4.5% of the horses. Only one animal was suspected of having a problem and pulled from the race following examination during the event. No significant association was found between CK levels and age, gender, muscle mass or temperament.
No association was found with receiving electrolytes during the race, although CK activity following the race was significantly higher for horses that received a fat supplement in their diet. Finally, the gene mutations associated with polysaccharide storage myopathy were not identified in any of the horses so the underlying cause of the condition in these mostly Arabian horses remains unknown.

Two papers reported on a study of shivers and stringhalt. The authors used their resources and web-based survey to obtain videos and descriptions of suspected cases of shivers (27 confirmed cases and 67 suspected cases) and stringhalt (seven cases). Similar information was also collected for…

Farasi wengi walikuwa wa Kiarabu au nusu ya Kiarabu, 75% walikuwa geldings na umri wa wastani ulikuwa miaka 11. Baada ya mbio, asilimia 38 ya farasi walikuwa na viwango vya creatine kinase (CK) vya juu kuliko vilivyoripotiwa kwa farasi waliopumzika. CK ni enzyme iliyoinuliwa kwa sababu ya uharibifu wa misuli unaohusiana na kuunganisha. Hata hivyo kiwango cha mwinuko ilikuwa sawa na ile iliripotiwa kwa farasi wa kawaida wa uvumilivu baada ya mbio. Kiwango cha juu cha CK, ambacho kinaonyesha kuwa farasi wamevaa vifungo, kilipatikana kwa asilimia 4.5. Mnyama mmoja tu alishukiwa kuwa na tatizo na aliondolewa kwenye mbio baada ya kuchunguzwa wakati wa shindano hilo. Hakuna uhusiano muhimu uliopatikana kati ya viwango vya CK na umri, jinsia, uzito wa misuli au tabia. Hakuna uhusiano uliopatikana na kupokea electrolytes wakati wa mbio, ingawa shughuli ya CK baada ya mbio ilikuwa kubwa zaidi kwa farasi waliopokea ziada ya mafuta katika mlo wao. Mabadiliko ya jeni yanayohusiana na myopathy ya kuhifadhi polysaccharide hayakutambuliwa katika farasi yeyote, kwa hivyo sababu ya msingi ya hali hiyo katika farasi hawa wa Kiarabu bado haijulikani.
