“…Algorithms C and D have poor accuracy in trot compared to A, B and E. Thus, it is notable that the maximal protraction and retraction for C and D do not correspond to hoof-on and hoof-off in trot. Peham et al (1999) do not discriminate between accuracy and precision for front limbs versus hind limbs. Our results support that it is not necessary to analyse the results separately for front limb and hind limb kinematics in walk, however, it is necessary to use different algorithms for hind limbs and front limbs during trot.…”

“…Hoof-on and hoof-off were extracted from motion capture using the following algorithms A-E (for further details, see supplementary table S1): Algorithm A (Peham et al, 1999) detects the beginning and ending of stance based on horizontal velocity of the distal dorsal hoof. The algorithm defines stance as the mode of fore-aft hoof velocity during each stride cycle.…”

“…Galisteo et al (2010) suggested algorithm B for use with video-based kinematics during over ground trot. Algorithm B is a modification of algorithm A (Peham et al, 1999) where hoof-on is detected using the absolute minimal fore-aft hoof velocity as a threshold. Hoof-off is defined as the angle of fetlock extension greater than 1801.…”

“…Different approaches have been investigated estimating timings for foot-on/off from motion capture for humans on a treadmill and walking over ground (Zeni et al, 2008) and humans running (Leitch et al, 2011), cats walking over ground (Pantall et al, 2012) and horses during walk (Peham et al, 1999) and trot (Galisteo et al, 2010). However, none of these algorithms have been tested and compared for horses during walk and trot on front and hind limbs.…”

Computerized rat gait analysis has become an invaluable technique of functional evaluation for some peripheral nerve investigators, comparing the normal and the pathological kinematic data. Appropriate selection of the methods to evaluate the functional outcome should be sensitive enough to moderate changes. By combining kinematic data and traditional methods in regeneration studies, it is possible to achieve better documentation of functional changes with the passage of time. A review of the three commonly kinematic parameters used in nerve regeneration studies, such as the calculation of sciatic function index, stance factor, and ankle angle, will provide the reader with detailed information about this accurate and consistent means of evaluating peripheral nerve function after nerve injury and repair. This study aims to review the different methods and potentialities of the rat gait kinematics as a noninvasive evaluation during regeneration, allowing for measurement of the rate of functional recovery in experimental studies.

Computerized analysis of rat gait is becoming an invaluable technique used by some peripheral nerve investigators for the evaluation of function. In this article we describe the use of a biomechanical model of the foot and ankle that allows a quantitative assessment and description of the ankle angle, reflecting plantarflexion and dorsiflexion during the stance phase of gait. Kinematic data of 144 trial walks from 36 normal rats were recorded with a high-speed digital image camera at 225 images per second. The ankle angular changes associated with the specific temporal events of foot placement on the ground through the stance phase were assessed. The information obtained was used to propose a new subdivision of the stance phase in the rat into three major components. This approach will provide a helpful research tool to analyze gait data that rely on the accurate determination of spatiotemporal foot events.
