“…Athletic taping is used routinely in human physical therapy and sports medicine to stabilise, maintain, strengthen or act as a substitute for well-defined biological structures (Neiger 1990). Taping has clear biomechanical properties that include increasing joint stability, decreasing articular range of motion (Alt et al 1999), stabilising injured ligamentous structures (Anderson et al 1992) and reducing tendinous vibratory phenomena (Neiger 1990). Other described effects include an increase in local tissue temperature (Alt et al 1999), improved proprioceptive response (Beynnon and Renström 1991;Anderson et al 1992;Alt et al 1999), limitation of muscular action (Hopper et al 1999) and increase of the athlete's confidence (Neiger 1990).…”

Summary Reasons for performing study: Athletic taping is used frequently by human athletes to stabilise, maintain or strengthen soft tissue structures, but empirical evidence supporting any changes in equine kinematics is lacking. Objectives: To assess the effects of athletic taping of the fetlock applied by an experienced athletic trainer on forelimb mechanics in healthy horses. Hypotheses: That athletic taping of the distal forelimb reduces hyperextension of the fetlock joint during stance, flexion of the fetlock joint during swing and 3) ground reaction forces during stance. Methods: Ground reaction force and kinematic data were obtained for 6 healthy horses trotting at 3 m/sec for 4 sequential conditions (baseline, untaped; pre‐exercise, taped; post exercise, taped post 30 mins trotting exercise; transfer, 4 h after tape removal). Data were analysed using 2‐way mixed ANOVAs (condition; joint). Results: A statistically significant interaction was identified for the fetlock during the swing phase (mean ± s.d. peak flexion at baseline 157 ± 4°, reduced with taping to 172 ± 4°; P<0.05) compared with no differences across conditions for the other joints. Peak vertical force reduced significantly (P<0.05) with taping. Conclusions: Athletic taping of the fetlock does not alter the kinematics of the forelimb during stance, but does limit flexion of the fetlock during the swing phase. The decreased peak vertical force may be due to an increased proprioceptive effect. Potential relevance: Reduced peak vertical forces may be of benefit in preventing or reducing injury. Further investigation remains necessary before it can be concluded that taping should be applied for tendinous or ligamentous rehabilitation in equine patients.

“…Wojtys et al 35 reported that the Lenox Hill brace (Lenox Hill Brace, Inc., Long Island City, New York) is effective in controlling internal tibial rotation under a 20 N·m torque load at 30° of knee flexion. In a later study, Anderson et al 3 compared the effects of a functional brace and athletic taping in five cadaveric limb specimens and found that knee bracing reduced anterior tibial translation by up to 20% and rotation by 16% at 125 N and 12 N·m of external loads, respectively.…”

Effects of Knee Bracing on the Sensorimotor Function of Subjects with Anterior Cruciate Ligament Reconstruction

The sensorimotor performance of the knee joint in 31 subjects who had undergone unilateral anterior cruciate ligament reconstruction at least 5 months previously was tested under three bracing conditions, 1) the DonJoy Legend brace, 2) a mechanical placebo brace, and 3) no brace, in random order. The accuracy of the subjects' ability to reproduce specified knee joint angles was tested as well as the isokinetic performance of their knee muscles at 60 and 180 deg/sec. The results showed that subjects with the brace or placebo brace performed similarly in reproducing the knee joint positions, but both groups performed better than the subjects without a brace. Isokinetic tests revealed no difference among the three groups in extensor and flexor peak torque production at 60 deg/sec or total work done by the extensors and flexors at 60 and 180 deg/sec. These results suggest that knee bracing can improve the static proprioception of the knee joint, but not the muscle contractile function, in subjects with anterior cruciate ligament reconstruction under isokinetic testing conditions. The finding of similar performances for joint angle reproduction in the brace and placebo brace groups suggests that the apparent improvement in proprioception with knee bracing was not due to the mechanical restraining action of the brace.

“…The efficacy of knee bracing is controversial. 3,13,14,26,37,43,44 Previous investigations of functional braces have been performed under various passive and muscle-activated loading conditions using arthrometers, 1,6,12,16–18,37,42,45,47,49,51,55,56 roentgen stereophotogrammetry, 31 and direct measurement of ACL strain. 9,11,23 Most of these studies have been limited in that they have not incorporated the dominant effects of body weight and muscle loading.…”

The Influence of Functional Knee Bracing on the Anterior Cruciate Ligament Strain Biomechanics in Weightbearing and Nonweightbearing Knees

et al. 2000

Functional knee braces are commonly prescribed after anterior cruciate ligament injury or reconstruction; however, their ability to protect the ligament, or graft, remains unclear. Our objective was to evaluate the anterior cruciate ligament strain response in braced and unbraced knees during weightbearing and nonweightbearing in combination with three externally applied loads: 1) anterior-posterior shear forces, 2) internal-external torques, and 3) varus-valgus moments. The Legend brace was tested. All external loads were applied to the tibia with the knee flexed to 20 degrees. Reproducible data were obtained from 11 subjects. For anterior shear loads up to 130 N, the brace significantly reduced strain values compared with the unbraced knee during nonweightbearing and weightbearing conditions. For internal torques of the tibia (up to 9 N x m), strain in the braced knee was significantly less than in the unbraced knee when the knee was nonweightbearing only. The brace did not reduce strain values when the knee was subjected to external torques (9 N x m) or varus-valgus moments (10 N x m) in weightbearing and nonweightbearing knees. These data indicate that a functional knee brace can protect the anterior cruciate ligament during anterior-posterior shear loading in the nonweightbearing and weightbearing knee and during internal torques in the nonweightbearing knee.
