Yes their shoulder is what may be screaming as the problem, but in reality it may have been the way they stand/breathe, their spine, or shoulder blades that are the issue and causes the shoulder pain to pop up. Shoulder rotation is measured with the arm abducted to 90 degrees, the elbow flexed to 90 degrees, and the forearm reflecting the midpoint (zero degrees) between internal and external rotation of the shoulder. The ankle joint is constantly exposed to extreme mechanical conditions during even the simplest motion, such as gait a hinge joint with only the ability to create flexion and extension freely in the sagittal plane, the ankle (tibiotarsal joint) controls movement of the leg relative to the foot. The evaluation of patients with neck pain donald r gore, md babinski's sign is the presence of dorsiflexion of the great toe when the bottom of the foot is stroked (figure 4. Dorsiflexion and the ankle the ankle is a hinge joint, and is only able to move (on it's own) through one plane of motion—the sagittal plane there are two movements within this plane, plantarflexion and dorsiflexion plantarflexion is the movement or pointing of the toes downwards (like a ballerina going on to her tip toes.
Dorsiflexion and plantar flexion refer to extension or flexion of the foot at the ankle these terms refer to flexion between the foot and the body's dorsal surface, considered the front of the leg, and flexion between the foot and the body's plantar surface, considered the back of the leg [25. A similar process can occur due to other injuries in the lower body, including knee pain, muscle injury, and even hip or back pain as an athlete limps or modifies their gait, the ankle joint can begin to tighten and limit range of motion. Dorsiflexion in the ankle is a huge player during gait it fits into the ankle rocker mechanism and will be the first movement example we look at watch this gait guys video of how the body would get around limited dorsiflexion in gait with these 6 compensation strategies.
Dorsiflexion is the movement of raising the foot upwards while this seems like a simple motion, there are many problems that can affect upwards motion of the foot learn about the potential. Ankle dorsiflexion weakness results in a lack of heel strike and decreased floor clearance this leads to an increased step height and prolonged swing phase   calf tightening or contractures due to a period of immobilisation or trauma will cause reduced heel strike due to restricted dorsiflexion. The ankle may be the most ignored joint next to the wrist in terms of athletic performance, flexibility, and injury preventionspeaking in terms of a structural integrity, the base is the single most important factor.
We cannot say that a shoulder injury is completely due to a lack of dorsiflexion we also can't say that that if an athlete has sustained a shoulder injury and they have come to you for help that simply fixing their dorsiflexion will fix their shoulder. Without an ankle dorsiflexion (knee to wall test) measurement, don't bother trying to get your ankle pain or foot pain fixed ~barefoot rehab so you have a calf, ankle, or foot problem hopefully, it hasn't gotten so bad that you have plantar fasciosis or achilles tendinosis. When we lack ample dorsiflexion, a whole host of issues can arise, including anterior knee pain, hip pain, and lower back pain so fixing it can go a long way in keeping people healthy in the long run. Research suggests, however, that changes in ankle rom could conceivably contribute to a mechanism for these as well as medial collateral ligament injuries, meniscal injuries, or chronic injuries such as patellar tendinopathy or patellofemoral pain syndrome 3 and, because ankle dorsiflexion motion absorbs up to half of the kinetic energy. Again, if we consider the interconnectedness of all the joints and limbs of the body then it may not surprise us that faulty foot/ankle movement could contribute to back knee pain, hip pain, back pain — even shoulder or neck pain.
The shoulder is the most flexible joint in your body, and given the number of everyday activities it's involved in—from brushing your hair to reaching up into the cupboard—it's easy to see why shoulder pain is something you'd want to get to the bottom of right away. The shoulder is a complex part of the body made of multiple tendons, ligaments, muscles, and a ball socket bone construction pain around the shoulder blade and shoulder injuries can be very uncomfortable and are easily aggravated by movement. Lack of dorsiflexion was accommodated for by adapting a compromised gait pattern bruising, swelling and a raised temperature were still present on the lateral side of the ankle cold weather conditions increased the pain however the patient was not dependent on. Symptoms of a rotator cuff tear are pain and weakness in the shoulder and a reduction in range of motion when lifting or rotating the arm impingement among the rotator cuff, there are bursa -- or small sacs -- meant to lubricate the joint. Due to limited ankle dorsiflexion, when you walk, the ankle will compensate for the lack of ankle mobility by external rotating and pronating (toe out gait) the exercises mentioned on this post will be perfect for you to improve your squat.
Lack of ankle dorsiflexion can lead to the body seeking other 'compensatory' ways of getting that shin over the foot, including dropping the medial arch, external rotation of the foot. This could cause excess movement in other areas within the hip/knee/low back right up to the shoulder we ideally have 10 degrees of ankle dorsiflexion during gait, and there are a number of common compensation patterns that are seen when ankle rocker (dorsiflexion during gait) is lacking. Dorsiflexion is the movement of the foot which is brought closer to the shin with the right amount of flexibility and mobility in the lower leg, you will get ankle stability and make it possible for you to adaptable while walking or running.
Toe extensor trigger points: referred pain from trigger points in the toe extensor muscles (extensor digitorum longus and brevis) is also projected to the top of the foot but is found more laterally on the top of the foot than the referred pain from the tibialis anterior. This lack of dorsiflexion of the 1st mtp joint can be associated with a lack of plantar flexion of the 1st metatarsal (ie the 1st metatarsal may be hypermobile in that it translates/rotates dorsally). One common form of shoulder arthritis is an autoimmune condition called rheumatoid arthritis (ra) you may have pain in both shoulders at once if you have ra.
