Tennis elbow, scientifically known as epicondylitis humeri, is used to describe a series of symptoms that occur with pain predominantly in the lateral aspect of the elbow joint. The clinical manifestations of this disease were first described by Runge in 1873. Currently, despite the initial view of an inflammatory process, most scholars believe that a small tear at the origin of the short extensor carpi radialis brevis is the etiology of the disease, and that the lesion is predominantly in the short extensor carpi radialis brevis, but can also affect the long extensor carpi radialis brevis and the common extensor digitorum brevis. My experience is that repeated use of the upper limb movements can lead to this disease, especially with the elbow, wrist flexion and extension of the rotational nature of the work, such as wringing the towel, moving, clicking the mouse, buckle the ball, turn over the hand to push the ping-pong ball and other actions, easy to cause the extensor tendon congestion, tearing, hyperplasia, scarring, mechanization, and even extensor tendon of fibrosis, calcification, so that the neurovascular bundles through the place of the compression of the pain, suffocation, pain, fatigue, and the tea cup, lifting a backpack. Tea cups, lifting backpacks are painful and unbearable, heavy described as irrigation of chili water like unbearable! The treatment of tennis elbow is mainly based on massage and physiotherapy in the early stage, and can be closed locally when the pain is heavy. However, a portion of patients with recurrent episodes, soreness, pain is very difficult to cure, and even several times closed, each time only a month or even shorter, the effect is getting worse and worse! This patient is a localized lesion is more serious, fascia, tendon sheath thickening embedded pressure neurovascular! The reason for the poor outcome may also be due to inaccurate diagnosis and treatment, because there are many extensor muscles, as well as the brachioradialis and posterior rotator muscles, which end at the lateral epicondyle of the humerus, and the correct diagnosis should be accurate to each muscle! There are also many causes of lateral elbow pain, and it is not something that can be solved by a doctor drawing a circle and a nurse giving a shot! In addition to the above mentioned treatments, self-stretching of the muscles is quite important in the recovery of tennis elbow. Wrist active range of motion: Flexion and extension – Wrist active range of motion in the direction of flexion and extension (with a 5-second pause at the end of each motion), 10-20 repetitions of each motion. Wrist stretch – wrist stretch in flexion and extension direction, stretching time about 1 minute, 3-5 times for each movement. Figure 2 left Forearm pronation and supination–wrist joint movement in internal and external rotation direction (5 seconds pause at the end of each movement), 10-20 times for each movement. Figure 2 Right: Active elbow flexion and extension – elbow flexion and extension (5 seconds at the end of each movement), 10-20 repetitions of each movement. In addition, strength exercises are essential for recovery and are a good way to prevent tennis elbow. Figure 1 Wrist flexion – Holding a can in your hand with your palm facing up, slowly raise and lower your wrist for 10-20 repetitions (you can gradually increase the weight of the can). Wrist extension – holding the can in your hand, palm facing down, slowly raise and lower the wrist in flexion 10-20 times (gradually increasing the weight of the can). Wrist radial deviation strengthening – holding the can in your hand with the thumb pointing up, slowly raise and lower the wrist in an upward motion for 10-20 repetitions (gradually increasing the weight of the can). Forearm pronation and supination strengthening – holding a hammer in your hand, apply force to the wrist in an inwardly rotating direction for 5 seconds, then apply force to an outwardly rotating direction for 5 seconds, 10-20 reps of each movement Figure 3 right Wrist flexion Holding a hose (broomstick) in your hand, slowly raise and lower your wrist for 10-20 reps. Note that this article is not intended to replace any diagnosis, treatment, or prevention of any condition. We hope that we can strengthen the awareness of sports protection, and in the event of an injury, we should ask a professional sports medicine doctor to evaluate the condition and develop a scientific rehabilitation and treatment plan, so that we can get a better post-injury recovery.
