Re: Centronuclear Myopathy

[Guest guest]

I don't know of a dog with the same disorder, but one of the case studies that was presented during my certification course was a young Shih Tzu that had been presented for assessment by a rescue group (that had limited funds).  The dog had such joint laxity that it could only stand for 15-20 seconds at a time.  It was determined by the orthopedic service that it needed bilateral FHO's and patellar surgeries, but the surgeons were concerned that it would never get up again if they proceeded without rehab first, in order to try and build some muscle strength.

The veterinarian who took on the case swam the dog because it was the only form of exercise that the dog could do, and even then, he could only swim very briefly to start.  At first, he was so weak that he couldn't remain upright in the water, and would roll like a log.  After several weeks of daily swimming, the dog began to improve both in endurance and muscle tone.  At the end of the presentation, the veterinarian showed footage of the dog running in the backyard with her own dogs. His gait was not normal, but the dog was running and playing--and the decision was made not to pursue any surgery at all on the dog at that time.

Hope that is of some use!  Being a Lab, swimming should come naturally to the dog, particularly if you can make it a game.Sally Suttenfield, DVM, CCRPhttp://www.fourpawsvetrehab.com/

 

Hi all,

I have a 4 year old male lab with a confirmed diagnosis of a centronuclear myopathy coming in next week. He was already assessed by the surgical department for lax hips and lax stifles (bilateral patella luxation). I do not know what his current level of disability is but was curious to know if anyone has any experience dealing with this or similar disorders and if you have found any modalities or therapeutic exercises of any benefit.

Thanks in advance for any words of wisdom.

Thanks Sally,That is my biggest question is if you could truly build up endurance or strength in these cases as most of them are labs which are already as "busy" as they can be with normal activity at home.TaraSent from my iPhone I don't know of a dog with the same disorder, but one of the case studies that was presented during my certification course was a young Shih Tzu that had been presented for assessment by a rescue group (that had limited funds).

Tara,

I did a search for comparative rehabilitation in humans. Apparently, dogs with

this condition are considered to have a mutation of the MTM1 gene encoding for

myotubularin, and are considered faithful genetic models of the disease in

humans. A review of the condition in humans suggests:

" As in other congenital myopathies, regular physiotherapy is aimed at the

preservation of muscle power and function and the prevention of contractures;

considering often prominent axial involvement, exercises promoting endurance and

truncal stability such as swimming and riding [160] may be particularly useful. "

(Jungbluth, H, Wallgren-Pettersson, C, Laporte, J. Centronuclear (myotubular)

myopathy Orphanet J Rare Dis. 2008; 3: 26.

From what I read, there seems to be quite a variability in the degree of

myopathy, so response would likely be unique to each case.

Hope that helps,

Nigel

Thanks Nigel for the info.For the PT's out there, anyone have experience in working with kids that have muscular dystrophies and improving/maintaining endurance?Thanks,Tara
