Plain-English summary
A group of German Shepherds with varying degrees of hip dysplasia was evaluated to see how their condition affected their ability to walk. The study found that dogs with severe hip dysplasia (grade E) had a significantly lower ability to bear weight on their back legs compared to those with mild dysplasia (grade C). This means that the more severe the hip dysplasia, the worse the lameness and mobility issues the dog experienced. Understanding this connection can help veterinarians better assess and treat dogs suffering from hip dysplasia.

Abstract
OBJECTIVE: To investigate the correlation between radiographic hip grade and kinetic parameters in German shepherd dogs. METHODS: Dogs were distributed into five groups of eight dogs each according to hip grade (A, B, C, D or E). Dogs were submitted to clinical evaluation and kinetic analysis. Five valid passages were analysed using data collected from a pressure walkway. Peak vertical force, vertical impulse and stance phase duration were evaluated at velocity (1 · 2 to 1 · 4 m/s) ±0 · 1 m/s(2) acceleration. Kinetic data between groups were compared. RESULTS: In pelvic limbs, mean peak vertical force decreased progressively from grade C (mild) to grade E (severe) hip dysplasia. The vertical impulse was decreased in groups C and E compared to groups A, B and D; stance phase duration did not differ significantly between groups. CLINICAL SIGNIFICANCE: Mean peak vertical force was lower in dogs with severe hip dysplasia compared with mildly dysplastic dogs. These results suggest that hip dysplasia degree can affect lameness severity.
