Abstract:
Stringhalt has been described as characterised by sudden and involuntary exaggerated flexion of one or both hind limbs. The aim of the study was to document differences in movement and musc1e activity ofhorses with sporadic stringhalt compared to sound horses. On the treadmill kinematic measurements and electromyographic measurements were done in 10 sound horses and in 6 horses with c1inical obvious stringhalt. Walk, Trot and triggered limb raises (LR) were measured. Horses with stringhalt raised and lowered their hind limbs significantly faster during limb raises. However, overall duration of the LR was similar in both groups. During the swing phase of walk and trat as wen as during LR the maximum height reached by the hoof marker was significantly higher in horses with stringhalt. At walk and trot the horses with stringhalt reached the highest point of the flight arc significantly later than sound horses. At the walk hock flexion and the difference between hock flexion and extension was significantly higher in horses with stringhalt compared to sound horses. At walk musc1e activity of the M. Semitendinosus showed significantly higher minimum, maximum, maximum - minimum difference and mean values in horses with stringhalt compared to sound horses. At trot the musc1e activity of the M. Gluteus medius and the M. Bizeps femoris showed significantly higher maximum, maximum - minimum difference, and mean values in horses with stringhalt. During LRs the M. Bizeps femoris and the M. Semitendinosus showed significantly higher maximum and maximum - minimum difference values. M. Longissimus dorsi and the M. Extensor digitorum longus had significantly higher mean values in horses with stringhalt compared to sound horses. At the walk, the order in which the musc1es reached the maximum aetivity within the motion eycle was similar for sound horses and for horses with stringhalt, whereas at the trot the order was different. The examined horses with sporadie stringhalt showed a signifieantly different movement eompared to sound horses at walk, trot and during triggered limb raises. Also, sporadie stringhalt ehanges muscle aetivity in more muscles than previously thought. In all muscles the stringhalt affeeted horses showed a higher muscle aetivity in one or more parameters investigated.
