Neuromyotonia in a horse
This article describes the clinical and electromyographic findings of neuromyotonia in a 19‐month‐old male crossbred Quarter Horse that presented with stiffness and muscle asymmetry in the hind limbs
Electrophysiological and histopathological findings of muscular disease suspected as myotonic dystrophy in a Shiba dog
TLDR
Results indicate that a mitochondrial abnormality partly play the role on the pathogenesis of present case.
Current status of myopathies affecting athletic horses
TLDR
The flourishing field of equine rehabilitation and regenerative medicine is driving the progressive application of a variety of modalities to the treatment and management of musculoskeletal conditions in horses, but it is essential that this be accompanied by appropriate scientific investigation to verify the efficacy of recommended modalities and treatment protocols.
Aspectos morfológicos de biópsias musculares em equinos com miopatia sob forma de surto
TLDR
This outbreak of equine myopathy was triggering for mitochondrial lesions, characterized by ragged red muscle fibers, probably due a breakdown homeostasis in vitamin E and Se, being compatible with nutritional myopathy diagnosis.
Biochemical and ultrasonographic evaluation of exertional rhabdomyolysis and myositis in draft horses
TLDR
It can be concluded that the sole use of US for the diagnosis of ER and myositis in investigated horses was not really conclusive, but a combination of serum biochemical analyses, clinical examination findings, and US could facilitate early diagnosis of the studied diseases.
Ultrastructural mitochondrial alterations in Equine myopathies of unknown origin
TLDR
Four out of five patients that did not fit into the usual algorithm to detect known causes of myopathy showed ultrastructural mitochondrial alterations and the possibility of a mitochondrial myopathy should be included in the differential diagnosis of muscle weakness.
Miopatías post anestésicas en equinos fina sangre de carrera
TLDR
It was observed that the dorsal recumbency is what causes most damage with respect to lateralrecumbency and left lateral position produces less damage than the right, and the degree of muscle damage be quantified through the study of serum enzymes CK, LDH, AST.

Skeletal muscle changes associated with equine myotonic dystrophy
SummaryA progressive neuromuscular disorder in young horses, clinically apparent as early as 1 month of age, is characterized by generalized myotonia, muscle stiffness, muscle weakness and atrophy.
Equine muscular dystrophy with myotonia
Progressive myotonia in foals resembling human dystrophia myotonica
A severe and progressive neuromuscular disorder accompanied by clinical, electrophysiological, and pathological features resembling human dystrophia myotonica was observed in three foals. This
Muscle glycogenoses
There are 11 hereditary disorders of glycogen metabolism affecting muscle alone or together with other tissues, and they cause two main clinical syndromes: episodic, recurrent exercise intolerance
Masseter myodegeneration as a cause of trismus or dysphagia in adult horses
TLDR
There were changes in the masseter muscle of all the horses, but some had widespread lesions in skeletal muscle, and a few also had myocardial lesions, and the serum activities of muscle enzymes were abnormally high in all of the horses.
Morphological alterations in oxidative muscles and mitochondrial structure associated with equine atypical myopathy.
TLDR
The morphological features gathered here reveal that EAM shares most of the characteristics of toxic myopathies, and the data suggest that a primary alteration of mitochondria should be considered, although secondary mitochondrial abnormalities have yet to be ruled out.
Skeletal muscle mitochondrial myopathy as a cause of exercise intolerance in a horse
TLDR
The exercise intolerance and muscle stiffness in this horse were attributed to a profound lactic acidosis resulting from impaired oxidative energy metabolism during exercise.
Canine inflammatory myopathies: a clinicopathologic review of 200 cases.
TLDR
The most common clinical signs in dogs diagnosed with an inflammatory myopathy were generalized weakness, stilted gait, dysphagia, masticatory or generalized muscle atrophy, inability to open the jaw, megaesophagus, and dysphonia.
Atypical myoglobinuria: an acute myopathy in grazing horses.
TLDR
The clinical syndrome and circumstances of the outbreak were not typical of equine exertional rhabdomyolysis (EER), and a number of potential aetiological and contributory factors were considered, but the aetiology remains unresolved.
