What is Achilles tendonitis?

The Achilles tendon is a strong tendon made of fibrous connective tissue that connects the calf muscle groups to the calcaneus and is an extension of the gastrocnemius and soleus muscles. This tendon is one of the strongest tendons in the body and plays a vital role in a variety of occupational and sporting activities.

Achilles tendonitis is a swollen and painful condition of the Achilles tendon, which MRI scans have shown to be due to collagen degeneration in the affected area rather than actual inflammation. This problem can affect different parts of the Achilles tendon, but generally occurs in and around the area where it attaches to the calcaneus bone.

Shoes can rub against the back of the heel, irritating the Achilles tendon and heel bone and causing what is known as a pump bump (an irritation at the back of the heel). This pain and discomfort can be alleviated by addressing the underlying cause of the shoe problem. For example, shoes that are too short from heel to toe or have heel counters that do not match the shape of the heel can cause this problem. Excessive heel bone movement during walking or activity may also be a factor in this problem.

Signs and Symptoms

Common signs and symptoms of Achilles tendonitis include

Symptoms of Achilles tendonitis

Redness and swelling due to inflammation of the Achilles tendon

Pain when the Achilles tendon is touched or moved.

Increased pain when running, jumping, walking, etc.

Swelling and pain may return after healing

Sensation of stiffness in Achilles tendon

Possible Causes

The most common causes (or contributing factors) of Achilles tendonitis include

Certain drugs, such as certain antibiotics and corticosteroids

Personal characteristics such as age, gender, weight, foot shape, walking style, etc.

・Position of the foot in conventional footwear and shoes

Rapidly transitioning from high heel running shoes

Bone-related problems such as arthritis and bone spurs

...Stiffening of the calf muscles.

Rapid increase in training volume and intensity for athletes

One factor that is often overlooked as a cause of Achilles tendonitis is the position of the foot and toes in footwear (socks) and shoes. In particular, the position of the toes can have a serious impact. By bending the ankle at 90 degrees and repeatedly bending and stretching the toes, the position of the Achilles tendon attachment site can be checked.

Mechanisms by which shoe construction increases strain on the Achilles tendon

Conventional footwear hastwospringoften has a built-in function called "toe deformity," which is responsible for deforming the foot and toes. However,twospringcan cause tension on the Achilles tendon and restrict blood flow to the back of the ankle. This can be a major cause of tissue degeneration around the ankle.

Achilles tendonitis caused by a sudden increase in training volume or intensity is called Achilles tendon overuse. A sudden switch from high-heeled shoes (including running shoes and high-heeled shoes) to low-heeled shoes can cause Achilles tendonitis. This is because prolonged use of high-heeled shoes causes the tendon to contract, requiring the Achilles tendon to stretch by up to 2 cm (in some cases). The stretching forces that the Achilles tendon undergoes from this are often sufficient to cause tendonitis-related signs and symptoms.

Mechanisms by which toe deformity increases stress on the Achilles tendon

toe deformityis the cause of Achilles tendonitis from a biomechanical perspective,Toe deformityThe following is a detailed explanation of how the Achilles tendon is affected by

toe deformityTo understand the relationship between the Achilles tendon and thetoe deformityand function of the Achilles tendon should be considered. The toes are an important part of human walking and running,Toe deformitychanges motor function and posture, which can affect the Achilles tendon in a variety of ways.

For example,Deformed toesThe arch of the foot collapses.Flat feetThis would reduce the plantar rebound function and may put stress on the Achilles tendon.Toe deformityprogresses and the inversion of the foot inward or outward (the motion of bending the foot inward or outward) becomes unstable, the Achilles tendon's ability to regulate tension is compromised, increasing the risk of overstressing the tendon.

toe deformityThe risk of Achilles tendonitis may be increased by imbalances in the ligaments and muscles of the foot due to the restricted range of motion of the ankle joint and unbalanced stress on the Achilles tendon. Progressive toe deformity and changes in the placement of the bones of the foot may alter the axis of motion and load distribution of the ankle joint, altering the stress distribution of the Achilles tendon and potentially contributing to inflammation.

Helpful treatments and exercises

The first (and most important) step in the conservative and natural management of Achilles tendonitis is to move from conventional footwear to Footwear for healthy feetThe first step is to move up to the next level. When choosing footwear, avoid shoes with bouncy toes, raised heels, or narrow toes.footwear that is good for the feetThe toes are the widest part of the foot and all toes are spread out (see Figure 1). YOSHIRO SOCKS(This movement can be further facilitated with the use of) The feet andCorrect position of toesHolding the toes in the toes optimizes circulation in the foot tissues and maintains a balance of muscle tension between the toe flexors and extensors/tendons.

It is important to change shoes slowly and in stages. It may take months to get used to the natural shape of the foot, especially if you are used to high-heeled shoes. Switching to shoes or sandals that do not put pressure on the affected area can also help with pump bumps. In particular.YOSHIRO INSOLEcan also help improve Achilles tendonitis.

YOSHIRO SOCKS

YOSHIRO SOCKSis the formation of the foot andposture correctionThe design is suitable forCorrect position of toesIt helps to keep the foot in a comfortable position. Proper stimulation of the foot is expected to strengthen the foot muscles and support the Achilles tendon.YOSHIRO SOCKSis effective in improving Achilles tendonitis by providing comfortable compression to the ankle and Achilles tendon due to its special weave and pressure distribution. In addition, the material is highly hygroscopic and breathable, which reduces steam and friction, resulting in a comfortable wearing experience. Furthermore, by supporting the ankle and Achilles tendon, it reduces strain during exercise and promotes improvement of pain and inflammation. Therefore,YOSHIRO SOCKScan be used to reduce or prevent symptoms of Achilles tendonitis.

YOSHIRO SOCKS designed to keep toes in proper position

Exercises that restore the normal position of the toes are effective in improving Achilles tendonitis. Supporting the arch of the foot can be achieved by spreading the thumb away from the second toe and holding it in line with the metatarsals. Orientation of the toes is also important,Proper toe positionand maintain a normal arch in the foot.YOSHIRO SOCKSand ... andgymnastics (esp. at Hironoba Gymnastics)By incorporating theProper position of the feetand support the arch.

To reduce stress on the Achilles tendon, it is important to have open toes.

gymnastics (esp. at Hironoba Gymnastics)

For Achilles tendonitis,gymnastics (esp. at Hironoba Gymnastics)is one effective method.gymnastics (esp. at Hironoba Gymnastics)is expected to alleviate and improve inflammation of the Achilles tendon by stretching to soften the ankle and training to strengthen the muscles. It also restores toe function, keeping the foot in the correct position in shoes and socks and greatly reducing the stress on the Achilles tendon.

Other Natural Remedies

Natural remedies for Achilles tendonitis include

autotherapy

Rest: Take adequate rest to avoid overloading.

Massage: relaxes muscles and improves blood circulation

Icing: cooling effect reduces inflammation

Hydrotherapy: training and massage in water

Therapeutic ultrasound: to reduce pain and inflammation

Nutrition: Consume a diet that changes the quality of your blood.

Reduce activities: Refrain from burdensome activities.

Introduce programs: Incorporate effective exercise methods and habits.

Stretching and strengthening exercises: Stretch the heels down slowly and perform reverse calf raises.

X-rays and MRI can be helpful in examining the Achilles tendon attachment area for the presence of osteophytes or calcifications. If such abnormalities are seen, the Achilles tendon may be damaged by these disorders during stretching, and thus there is a risk that stretching may exacerbate symptoms.

Achilles tendonitis is a serious health problem and needs to be treated as soon as possible. If left untreated, the pain can become chronic and scar tissue can form. Scar tissue reduces the flexibility of the Achilles tendon and increases the risk of a complete rupture (the Achilles tendon tearing away from the heel bone or splitting into two separate parts).
