Still can't get up the steps after knee replacement? Just because I missed it!

Among the elderly, knee joint diseases, cardiovascular diseases, diabetes and tumors are called the four major geriatric diseases. According to statistics, 80% of osteoarthritis occurs in the elderly aged 55-65, and the incidence rate increases with age. Although the disease is not immediately life-threatening, its pain seriously affects the normal life of the elderly. In order to solve this problem, knee replacement surgery has become popular, and the number of operations is increasing every year.

However, simply completing knee replacement surgery does not mean that the pain is solved, let alone that the patient has the ability to walk normally. We meet many patients who are still troubled by knee problems after knee replacement surgery. Postoperative patients often have such a question: "It has been a long time since the operation, why can't I go up and down the steps?" Some people complain that "my legs are always boring and I will get tired after walking for a while"-what is the problem?

Myth: Do you need to rest for 100 days after a bone injury?

For the people of China, the phrase "it hurts the bones for a hundred days" is absolutely deeply rooted in the hearts of the people. In fact, the so-called "rest" is very learned. If not handled properly, it will bring more problems in the future. Many friends after operation, in order to make their recovery "faster and better", lie in bed and rest honestly all day except going to the toilet. As a result, careful people soon discovered how the thighs became "slim".

Friends, this is not fat reduction, this is naked "muscle reduction"!

As long as the lower limbs are in a state of no load and no targeted training is done, muscle fibers begin to lose. Soon after a week, the muscles will become smaller and looser with the naked eye. This is the beginning of atrophy, which is called "disuse muscular atrophy" in the professional field.

When knee joint diseases occur, the most common site of disuse muscular atrophy is the quadriceps femoris. The quadriceps femoris, located in front of the thigh, is one of the largest and most important muscle groups in the human body, and it is the main source of strength when we walk, go up and down stairs and squat. Once the muscles atrophy, the knee joint will be unprotected and unstable, which not only aggravates the symptoms, but also is not conducive to the rehabilitation of the knee joint. Therefore, it is necessary to strengthen the muscle strength of quadriceps femoris through rehabilitation training, improve the stability of knee joint and improve local blood circulation and metabolism, so as to relieve pain and recover as soon as possible.

Studies have shown that before traditional total knee replacement (TKA), patients with knee osteoarthritis generally have 20% symptoms of quadriceps femoris weakness. Even if the basic standardized rehabilitation course is carried out immediately after operation, the muscle strength of quadriceps femoris can be weakened by 40% within one year after operation. At the same time, the researchers said that the defect of quadriceps femoris is also closely related to the slow walking speed and the decline of climbing ability.

Now I realize the problem of muscle atrophy caused by lying down and resting. However, the wound has just healed with pain after the operation, so it is impossible to carry out high-intensity or weight-bearing training on its own. How to maintain muscle content?

Correct rehabilitation posture: neuromuscular electrical stimulation improves quadriceps femoris muscle weakness

Neuromuscular electrical stimulation (NMES) is a method of stimulating motor nerves and muscles with low-frequency pulse current to cause muscle contraction. The motor nerve impulse caused by NMES is consistent with that of the brain during active exercise, so its effect of developing muscles is similar to that of exercise. The researchers combined neuromuscular electrical stimulation (NMES) with traditional muscle strength training for postoperative rehabilitation. The results show that patients who receive NMES walk faster than those who receive traditional strength training, and reduce the disadvantages caused by muscle torque.

? From February, 2065438 to February, 2007, according to the research report of JOSPT, patients began to receive rehabilitation courses combining traditional strength training with neuromuscular electrical stimulation 48 hours after total knee replacement. The researchers followed up the quadriceps femoris muscle strength and muscle fiber activation degree of surgical limbs and healthy limbs for 3 weeks, 6 weeks and 12 weeks. The results showed that the activity of quadriceps femoris increased from 72.9% to 93.5% after 12 weeks. The muscle strength of the affected limb increased by 56% compared with that before operation, even exceeding that of the healthy limb.

It can be seen that electrical stimulation can effectively maintain or even improve muscle strength. So what is the function of neuromuscular electrical stimulation? We answer this question from the following three aspects-

The basic principle of electrical stimulation mode: wake-up mechanism

Neuromuscular electrical stimulation will selectively recruit fast muscle fibers first. Fast muscle fiber is the first muscle tissue lost in disuse muscular atrophy. Therefore, neuromuscular electrical stimulation provides the necessary nerve drive for stimulating quadriceps femoris, thus inhibiting the negative effects of disuse muscular atrophy. According to the statistics of American academic journal Sports and Exercise Medicine and Science in 2005, neuromuscular electrical stimulation can increase muscle strength by 27%.

? Reducing the inhibitory effect of postoperative swelling on the muscle strength of quadriceps femoris

Clinically, it is also confirmed that neuromuscular electrical stimulation applied to quadriceps femoris after operation has the function of pumping (muscle pump), promoting blood circulation rate and reducing tissue swelling.

Increase the maximum oxygen uptake and reduce the lactic acid content in the blood.

For the infirm, comprehensive rehabilitation after operation combined with general strength training and neuromuscular electrical stimulation can reduce the pressure of exercise on cardiovascular system and the accumulation of lactic acid produced during exercise. After the exercise, electrical stimulation exercise can also effectively relieve muscle soreness and tension.

Speaking of this, I believe many friends will be concerned about what kind of people can receive neuromuscular electrical stimulation treatment, treatment cycle, treatment intensity, any contraindications or side effects and so on. These parameters need to be controlled by professional physiotherapists through strict standards. You don't have to worry about our professionals in China Kangmeifu.

Remember, neuromuscular electrical stimulation will bring:

?

Recover faster!

More effective activation!

More motivation!

? Less damage!

? More? Is it steady? what's up Promise? Barriers !
