A "locking foot" can refer to a dangerous submission hold in Brazilian Jiu-Jitsu (BJJ) and combat sports, aiming to hyperextend the ankle joint (a straight ankle lock) or twist it, potentially causing serious injury. It can also refer to a sewing machine presser foot with a stabilizing feature, used for sewing over thick areas or inserting elastic, ensuring even stitching.
An ankle lock (occasionally referred to as a shin lock) is a leglock that is applied to any of the joints in the ankle, typically by hyperextending the talocrural joint through plantar hyperflexion.
This could be the result of a torn ligament, a bone fragment, or even a dislocation. These conditions might cause a sensation of the joint getting stuck or locked in a certain position. Conditions like ankle impingement or loose bodies within the joint can also lead to similar sensations.
Sitting on a chair, bend the leg of your injured foot up onto the thigh of your other leg. Gently pull your foot inwards and upwards towards you. This exercise will help improve mobility to the ankle. Do this 10 times to mobilise a stiff ankle.
You may feel pain primarily at the lateral (outside) or medial (inside) point of the ankle joint. Severe locking or catching symptoms, where the ankle freezes up and will not bend, may indicate that there is a large osteochondral lesion or even a loose piece of cartilage or free bone within the joint.
Calf locks are extremely painful and can cause injury to both the calf muscle and the knee joint when applied successfully.
Wear a compression wrap and elevate the injured ankle above heart level to reduce swelling. You can also gently flex and extend (point your foot up and down) the affected foot as often as you can. Working on early range of motion promotes healing.
Signs And Symptoms Of Chronic Ankle Instability
Ankle locks are allowed in all belt ranks, moving from white to black. They are also legal moves in the BJJ Gi and No Gi tournaments.
Sometimes an ankle sprain or other condition will stop the joint from doing its work, and the ankle joint seems to lock up. This might be the result of a chip of bone or fragment of cartilage that is caught between the two bones. It can feel like gravel is in the ankle joint, and it is common among younger athletes.
Foam rolling: Place your calf muscles on top of a foam roller and simultaneously drive the leg down and flexing and extending the ankle. Ankle dorsiflexion stretch: Start in a lunge position with both legs bent to roughly 90 degrees and grabbing onto a stationary object such as a squat rack.
An important part of recovery is early weight bearing following the sprain. In fact, walking on the sprained ankle can actually improve recovery and stimulate stronger healing of the injured ligaments and tendons.
If you have an acute injury such as a sprain or strain, then using an ice pack can help to reduce inflammation and numb the pain. If you are experiencing chronic pain or stiffness, a heating pad can help to increase blood flow and loosen up tight muscles.
Pain may be felt primarily at the lateral (outside) or medial (inside) aspect of the ankle joint. Severe locking or catching symptoms, where the ankle freezes up and will not bend, may indicate that there is a large osteochondral lesion or even a loose body (loose piece of cartilage or bone free within the joint).
It's designed to put pressure on your opponent's ankle and is without a doubt the most painful hold there is. If applied properly, on a scale of one to 10, it's about a nine-and-a-half. In all seriousness, it's a really dangerous hold and you have to be careful when you apply it.
The treatment for anterior impingement in the ankle can include physical therapy to help improve the range of motion and break down scar tissue, anti-inflammatory medications to relieve pain and swelling, and ultimately surgery to remove the tissue or bone that is causing the blockage.
Sometimes, an ankle sprain needs more than at home remedies—and ignoring a moderate or severe sprain can lead to long-term instability, weakness, or chronic pain. You should see a podiatrist if: You heard a pop or felt a sharp snap when it happened. Pain is severe and doesn't improve within 48 hours.
