Background Low load exercise training with blood flow restriction (BFR) has become increasingly used by human physical therapists to prescribe controlled exercise following orthopaedic injury; its effects on the equine superficial digital flexor tendon (SDFT), however, are unknown. Objective To investigate outcomes of pressure specific BFR walking exercise on uninjured equine SDFT biomechanics and histomorphology. Study design Controlled in vivo experiment. Methods Four forelimbs of four horses were exposed to 40 BFR‐walk sessions (10‐min interval walking) on a treadmill over a 56‐day study period with their contralateral forelimbs serving as untreated controls. Similarly, four forelimbs of four control horses were exposed to 40 sham cuff walk sessions. On study Day 56, all horses ( n = 8) were humanely euthanised and forelimb SDFTs underwent non‐destructive biomechanical testing and corresponding histomorphological analysis. Significance in biomechanical parameters between treatment groups was analysed using a mixed‐effects ANOVA with Tukey's post‐hoc tests. Results Statistically significant differences in SDFT stiffness for both first ( p = 0.02) and last cycles ( p = 0.03) were appreciated within the BFR treated group only, with BFR exposed forelimbs being significantly stiffer than the contralateral unexposed forelimbs. When normalised to cross‐sectional area, no significant differences were appreciated among treatment groups in elastic modulus for the first ( p = 0.5) or last cycles ( p = 0.4). No histological differences were appreciated among treatment groups according to Bonar, Movin, or musculotendinous junction evaluation criteria. Main limitations Short‐term comparisons were performed in a small sample population without correlation to performance outcome measures. Optimal occlusion percentages and walk protocols remain unknown. Conclusions This study demonstrated no negative impact of BFR on mechanical strength of the equine SDFT; however, evidence suggests that BFR results in increased ... |
