Beschreibung
The aims of this study are the sonographic representability and description of canine fascia tissue and a clinical measurement of thickness of the superficial fascia (Fascia trunci superficialis) and the lumbar fascia (Fascia thoracolumbalis) of sighthounds in sport.
Based on the sub-study on a dog carcass, it can be proven that ultrasound can also be used in dogs for the evaluation of fascial thickness.
The layer thickness of the superficial fascia (Fascia trunci superficialis) and the lumbar fascia (Fascia thoracolumbalis with Lamina superficialis/dorsalis) and the total thickness of both parts are measured by ultrasound bilaterally at the level of the 6th lumbar vertebra of sport dogs (group 1, n = 25) during training and training break. The group of sport dogs is compared with a group of hobby sighthounds (group 2, n = 17).
The lumbar fascia (Fascia thoracolumbalis with Lamina superficial/dorsalis) of group 1 has a sonographically detectable change in thickness. Training of sighthounds leads to a significant (p < 0.05) decrease in thickness by 19 % from 0,95 mm to 0,77 mm. The superficial fascia (Fascia trunci superficialis) is thinner than the Lamina superficialis/dorsalis and its layer thickness remains constant (0,75mm). The total thickness (superficial and deep fascia with deep adipose tissue) of all dogs in group 1 shows no significant change. The deep fat layer as a proportion of the total thickness is 24% thinner during training. There is no significant body side or gender difference.
All fascia parts of group 2 are significantly thicker than those “untrained” of group 1: the superficial fascia (1,34 mm) is 43% thicker and the Lamina superficialis/dorsalis (1,33 mm) is 27% thicker. In comparison, the total thickness (superficial and deep fascia with deep adipose tissue) is 26% and the deep adipose layer is 7% thicker in group 2. There is no significant body side or gender difference.
Sporting use that goes beyond everyday movement seems to affect the layer thickness of fascia not only temporarily but also in long term and "thin" fascia could be evaluated as a positive physical characteristic.
This study presents a standardized measurement protocol of the thoracolumbar fascia thickness in cross section at level L6 of sighthounds in ultrasound, which could serve as a model for subsequent studies.
