Evaluation of a pressure-sensitive treadmill in normal cats.

Pressure-sensitive treadmill is feasible, reliable, and practical for feline kinetic gait assessment.

This prospective study evaluated the feasibility and reliability of pressure-sensitive treadmill technology for kinetic gait assessment in normal cats. Fifty cats without orthopaedic disease were acclimated to the equipment and walked until three valid trials of 10 gait cycles were obtained. The researchers measured peak vertical force, vertical impulse, symmetry index, step phase duration, and step length for both forelimbs and hindlimbs. Results demonstrated forelimbs generated higher forces (57.5±4.2 N peak vertical force) compared to hindlimbs (46.4±3.8 N), with excellent symmetry indices near 1.0 for both limbs. Data collection required only 3.5±1.5 minutes per cat. The pressure-sensitive treadmill proved to be a reliable, rapid, and practical tool that cats tolerated well. The authors conclude this methodology could establish standardized protocols for feline gait analysis, enabling consistent comparisons across studies and facilities—particularly valuable given the typically limited patient populations at individual feline practice facilities.
