A gentled, elderly Mustang mare who struggled to bend to the left for the 3 years prior to our first session. She was 21 on our first session, and I have seen Kid twice. Kid is a great example of the need to get to the root cause + interconnectedness in the body.
Kid now lives in semi-retirement from gymkhana and enjoys life with her little boy riding along as well.
During Kid's first session I focused heavily on her lateral movements of the neck, releasing the poll, the jaw and the shoulders. I worked back and forth, and focused heavily on her front end. She was able to move to the left when I went to the hind end but she was so used to it, she continued to look around to me at the left hind via the right side of her body until the last 15 minutes of her session. I never guarantee, but I do try as much as the horse will give.
After our session, Kid began to act tender-footed, especially on the fronts. We gave a few weeks to adjust and consulted the farrier, but with nothing else found I suggested the teeth be checked once more. When the owner was able to, the horse was floated and this alleviated the appearance of sore feet. Really, Kid had learned (which is why the soreness wasn't immediate after our session) to walk carefully to minimize the implications of the dental imbalances, buffering the impacts and discomfort.
Some Forelimb + Head connections, muscularly:
Brachiocephalicus: Extends limb and draws cranially, bends head laterally + rotates it.
Origin: Mastoid process of the temporal bone (skull), Insertion: Clavicular intersection.
Omohyoiddeus: Retracts hyoid bone, Origin: subscapular fascia Insertion: Hyoid apparatus
Omotransversarius: Pulls limb cranially, unilateral action flexes neck laterally. Origin: Transverse processes of C2-4, Insertion: Brachial fascia (often considered part of the brachiocephalicus muscle)
Trapezius: Draws limb cranially and caudally and abducts it. Cervical part pulls scapula cranially. Origin: Nuchal ligament and supraspinous ligament of C2-T10, Insertion: spine of scapula.
Rhomboideus: Adducts and pulls shoulder dorsally and elevates neck. Origin: Nucahl ligament, dorsoscapular ligament. Insertion: Scapular cartilage
