Location: Anchors on to the tuber coxae, inserting into the fascia lata, lateral patella ligament, cranial border of the tibia, and third trochanter with the superficial gluteal muscle.
Function: Extends stifle, draws limb cranially (forward), contributes to hip flexion and abduction, tenses the fascia lata to stabilize the limb on the ground. The TFL is usually active for a longer period of time in canter, showing the need for more support and stabilization of the joints in faster gaits.
You can see your horse’s TFL in action if you stand by its hips, take the tail and gently pull it towards you. Your horse should stabilize itself using the TFL. This can be a good in-barn exercise for those looking to strengthen this area although there are contraindications for every exercise. Please consult your Vet before introducing this exercise to your horse.
Dysfunction: Traveling downhill will cause problems if the extension of the stifle is inhibited due to the tension in this muscle. A weak TFL may have issues with instability, especially in canter or jumping, and lateral movements. Poor development of the muscles that fill the triangle between the tubor coxae, stifle and femur (tensor fascia lata & quadriceps femoris) will be accompanied by lack of power, and may increase stress the stifles and back.
Once you’ve cleared any and all underlying issues with your Vet, your Equine Massage Therapist can help you to carefully develop this very active muscle.
Strength training may include careful use of exercises that encourage the horse to elevate its hind limbs and gentle hill work.
