According to media reports, a well-known artist practiced dancing vigorously for the new album, and her chronic illness worsened at all costs. She has been learning ballet for 11 years since she was 3 years old. Due to the cartilage injury of her right knee, she used to use her left foot to work hard and turned into long and short feet. Because of long-term poor sitting posture, she likes to bend over and hunch back, which makes her long and short feet more serious. Now it has become her exercise. Secret worries when practicing dance.

Another news article reported that “the length and short feet of the car accident were abandoned, and the beauty “painted” the healing wounds”: It describes a sweet-looking painter in Kaohsiung who suffered a serious car accident at the age of 20 and almost lost her right foot. Although it was retained, she left his long and short feet. Her sequelae, coupled with her boyfriend leaving without saying goodbye, made her want to commit suicide for a while. Fortunately, her family supported her all the way, and she also worked hard to focus on her favorite painting and finally walked out of her own world again.

We often hear long and short feet in our lives. If someone has physical aches or sports injuries, they will hear: “You have long and short feet!” When the shoes are worn out, go buy shoes. The clerk looks at the shoes that are about to be reimbursed, and says faintly, “Your soles wear unevenly on both sides. Maybe because of the length of the feet, it’s best to make insoles to correct them.” When parents saw their babies walking in a weird posture, the standing posture was always three or seven steps. Anxiously brought to the hospital to ask a doctor to check for long or short feet or scoliosis.

The incidence of long and short feet, the data available in the literature range from 30% to 70%, but the incidence observed in clinical practice is probably much higher than this number. However, foreign studies have found that if the difference between the feet is more than 0.3 cm, it will cause abnormal body posture; if the gap is more than 0.6 cm, it may cause the pelvis to tilt and cause scoliosis. If the more serious length of the feet is not corrected, it will lead to low back pain, sciatica, hip joint degeneration, hip bursitis, iliotibial tendonitis, knee joint degeneration, knee sprain, and plantar fascia in the long term. Inflammation, forefoot pain, hallux valgus… and other chronic painful diseases of lower limbs.

Long and short feet can be divided into two types:

1. Structurally long and short feet, also called “true” long and short feet, means that the two feet’ actual length is different. It may be due to the inconsistent growth of the two feet (rarely), or the sequelae caused by traumatic fractures, tumors, and infections.

Treatment: use insoles or soles to thicken the solution

The structural length of the foot has been shaped, and the treatment must be corrected in an “external” way. The most common example is to add an insole to the shorter foot.
The principle of making the insole is to configure the insole for correction when the difference between the feet is more than 1.5 cm. The insole placed in the shoe can be used first. High arch feet) to individually correct. But if the difference between the two feet is too large, the sole must be thickened on the outside of the shoe to keep the difference between the two feet within 0.5 cm.
Structural long and short feet need to be actively corrected, to avoid future pelvic tilt or scoliosis, which may be complicated by functional long and short feet.

2. Functional long and short feet, also called “pseudo” long and short feet, refers to the fact that the actual length of the two feet is equal, but due to other factors, the two feet are asymmetrical during physical activity. It may be caused by a skewed pelvis, scoliosis, excessive muscle tension on one side, or abnormal foot shape.

Most of the long and short feet are functional long and short feet, and they are often caused by long-term poor posture. For example, because of the spine’s scoliosis, the man’s upper body in the picture bends to the right. To maintain the balance of the body, the pelvis becomes high left and low right. The lower limbs connected to the hip joint become longer and shorter due to the tilt of the pelvis, becoming functional lengths. foot.

There is also a very common situation that occurs in office workers who have been sitting for a long time. Sitting and standing for a long time will keep the deep muscles of the waist in a tight and tight state, which will make the pelvis tilt forward. If the body is often habitually tilted to one side, it will also make the left and right muscles unbalanced. Causes pelvic crookedness. The habitual swaying of Erlang’s legs, or a preference for sitting cross-legged in a chair (especially female friends), will make the muscles near the hip joint more uneven and worsen the functional length of the feet in the long run.

Treatment: Strengthen the stability of the muscles around the pelvis

The principle of treatment of functional long and short feet is not just to raise the short side feet with insoles. Instead, it should be treated for its underlying causes, such as moderately relaxing tight muscles, correcting the pelvis with freehand therapy, and then allowing yourself to make fundamental adjustments in living habits, sitting, and standing according to the recommendations of the doctor or physical therapist.

More importantly, let yourself develop specific exercise habits to strengthen the stability of the muscles around the pelvis. Pilates and yoga are good choices.

Although long and short feet are common in most people, most of them can be corrected. Any long or short foot needs to undergo detailed diagnosis and careful evaluation, and after professionals have done body inspection, bone position palpation, and human mechanics analysis tests, can you diagnose the real problem and allow yourself to receive the most effective treatment.
