“…The mean force applied in this study (about 150 N) corresponds well with the values reported by Nilsson and others (1973), Von Plocki and others (1988) and Verschooten (1990). Such a force will result in a moment on the fetlock joint of about 28·5 Nm.…”

“…Some work has been done on the forces involved in the performance of the flexion test (Nilsson and others 1973, Keller 1983, Schröder 1985, Verschooten 1990, Verschooten and Verbeeck 1997) and the need for a standard method of performing the test, especially in the case of purchase examinations, has been emphasised by Von Plocki and others (1988). However, textbooks offer far from standard, if any, guidelines on how to perform the test.…”

Variations in the force applied to flexion tests of the distal limb of horses

et al. 1997

A pressure-sensitive device was developed to measure the force applied to flexion tests of the distal limb of horses. The mean force applied by a group of experienced clinicians was 150 N which results in a moment on the flexed fetlock joint of about 28.5 Nm. The coefficient of variation of the force applied by one experienced clinician was only about 12 per cent, but the coefficient of variation between clinicians was considerably higher (20 per cent), irrespective of whether the clinicians were considered to be experienced or not. The mean force applied by a group of women examiners (114 N) was significantly lower than that applied by the group of male examiners. It is concluded that the flexion test used in the clinical examination of the locomotor system of the horse should be better standardised.

“…The only textbook which comments on the force to be applied is that by Wyn‐Jones (1988), who says that it is an important factor without further quantifying the statement. In the few publications which comment on the force to be applied when performing the flexion test, forces of 100 N (Verschooten and Verbeeck 1997) and 150 N (Nilsson and others 1973, Von Plocki and others 1988, Verschooten 1990) have been mentioned. Keller (1983) advises a flexion test lasting 90 seconds with a force of 200 to 300 N. He claimed that these relatively large forces were based on a study of 10 horses, but no full results were given and the method by which the forces were measured was not described.…”

Influence of the force applied and its period of application on the outcome of the flexion test of the distal forelimb of the horse

et al. 1997

The influence of the force applied and its period of application on the outcome of the flexion test of the distal forelimb was investigated in a group of eight sound horses. The degree of lameness after the flexion test was scored by a standard clinical classification, and by measuring the angle of maximum fetlock extension by means of the infrared light-based MacReflex gait analysis system. There was a good correlation between the clinical score and this electronically recorded kinematic parameter (r = 0.96). Both the force applied and the period of application affected the outcome of the test. Increasing the force applied by 25 per cent led to three horses being judged positive, instead of two when the normal force was applied. Doubling the time to 120 seconds resulted in four horses rather than two being classified as lame after the test. Reducing the force to 75 per cent or the time to 30 seconds resulted in all the horses being classified as sound. A flexion test lasting five minutes, either at 100 per cent force or at 75 per cent, classified six of the eight horses as lame. It is concluded that the flexion test should be defined more precisely in terms of these two factors in order to make its results more consistent and hence more useful.

“…Das im Hippiatrika-Verlag erschienene, von einer Expertenkommission vor nunmehr 15 Jahren im Auftrag der damaligen Deutschen Tierärzteschaft erarbeitete Untersuchungsprotokoll hat in der Vergangenheit, d.h. nach altem Recht, viele Stürme und Angriffe erlebt und überlebt (Plocki et al 1988). Ungezählte eigene Kreationen mit mehr oder weniger großen Abweichungen wurden geschaffen, immer mit dem Hintergrund der Vereinfachung oder der individuellen oder auch selektiven Zusicherung in Richtung Hilfe für die Kaufentscheidung oder als Prädikat für den Verkäufer.…”
