Clinical strength training for knee osteoarthritis

The change of muscle strength around the knee joint is the most direct and initial factor causing the decline of joint function, and studies have shown that muscle strength decline has important significance in the beginning and progression of knee osteoarthritis course, strengthening the muscle strength around the joint, relieving pain and improving joint function
.

Since the quadriceps play an important role in maintaining knee stability, most strength training methods focus on this, so here are several training methods
aimed at improving quadriceps muscle strength.

1 quadriceps isometric contraction training

Definition: isometric contraction, that is, muscle fibers contract, creating tension, but does not cause joint movement, limb displacement
.

Steps:

1) Supine position, both lower limbs straight;

2) Tighten the quadriceps, that is, the muscles in front of the thighs, and also use a little force to help the knees press down to tighten and bulge the muscles in front of the thighs;

3) Relax after maintaining for 5s and repeat 10-15 times
.

Suitable people: the elderly, patients with a lot of joint effusion, and patients
in the acute inflammatory period.

2-quadriceps isotonic contraction training

Definition: Muscle movement
performed under constant resistance load.

Steps:

1) Supine position, training side lower limb extension position;

2) Contralateral knee flexion 90°, train the ankle of the side limb to dorsiflex, tense the limb up to the level of the contralateral knee joint;

3) Maintain for 5s, relax after falling, and repeat 10 times;

Suitable for: Patients after
the acute stage.

3-strand quadriceps isokinetic contraction training

Definition: Isokinetic strength training is a new muscle training technique that often needs to be assisted
by specialized functional exercise equipment.
By adjusting the application resistance of the instrument (at a constant speed), the muscles can contract at all angles during the exercise to generate the maximum tension, so as to facilitate the maximum contraction ability of the muscles and achieve the best training effect
.
Different instruments move in different
ways.

Tips: This article only lists several main muscle strength training methods, advocating patients to pay attention to exercise therapy for osteoarthritis, enhance confidence, there are other knee muscle group exercise therapy, can be combined with active, passive performance, specific consultation with relevant specialists
.

Notes:

1.
Exercise therapy cannot completely replace drug treatment, and cannot be stopped without authorization;

2.
Train under the guidance of a physician as much as possible;

3.
Training intensity equivalent to force
.
