Description

Elbow joint is painful with protection protective equipment

Technical Field

The utility model belongs to the technical field of the medical treatment protective equipment, concretely relates to elbow joint is painful with protection protective equipment.

Background

The major pathogenesis of Lateral Epicondylitis (LE) is the strain or injury of the extensor carpi radialis muscle due to insufficient muscle strength of the supinator muscle, which is either a grasping action or an antagonistic muscle, and degenerative changes, of which the change of the extensor carpi radialis is the most common. Causing tendon deformity, degeneration and tearing at the origin of the muscle, which is painful (Garg et al 2010; Nirschl and Ashman 2003; Kroslav and Murrel 2007).

It is characterized by pain on the lateral humerus, extension of the wrist joint, increased pain and reduced grip strength on the posterohumeral lateral epicondyle (Garg et al 2010; Struijs et al 2005) and sensitivity of the proximal muscle group of the radius (Trudel et al 2004). Although lateral epicondylitis is also known as "tennis elbow", LE (Garg et al.2010) present in tennis players is less than 5-10%, actions that occur in various types of excessively repetitive tasks, including repetition of grasping actions, or the process of pronation to supination, are more likely to cause the appearance of LE (Garg et al 2010; krollav and Murrel 2007; Anderson and Rutt 1992) including surgeons, musicians, housewives (Anderson and Rutt 1992), construction, installation occupations, manufacturing and feeding processes (Trudel et al.2004). The probability of 40-50% of tennis players appearing describes the annual incidence of 1-3% of the general population (G Garg et al 2010; Bauer and Murray 1999; Meyer et al 2002).

The current situation and the problem:

domestic and domestic

Treatment modalities for LE are diverse, including rest, ice compress, physical therapy, non-steroidal anti-inflammatory drugs (NSAIDs), topical injection, exercise therapy, functional elbow support, platelet rich plasma injection, botulinum toxin injection, and surgery, however, the best treatment remains an open question [ TANG H Y, YU T, WEI W, et al 2019 ].

2. Relevant documents 1554 are searched by the Chinese knowledge network by taking the external humeral epicondyle as a key word, wherein more than 1140 documents are traditional Chinese medicine treatment methods, and then shock wave treatment, local injection treatment, operation treatment and platelet injection treatment are carried out. Therefore, the LE treatment mode in China is mainly the traditional treatment mode and the anti-inflammation of the medicine. And inconsistent with the expectation of recovery of the patient. And these approaches are only useful as a treatment for post LE onset pain without altering the relatively altered humeral-radial relationship and the unbalanced extensor carpi and supinator forces. The recurrence rate of the previous methods is high, and the research on braces is rarely reported.

3. While the treatment method of attempting to treat LE by adopting MWM (metal wrap) by using Mingjin (2021) is simple sticking treatment, the sticking treatment has the obvious defects of long time consumption, easy allergy of sticking cloth, easy falling of sticking cloth, high economic cost and time cost and incapability of popularization.

4. Elbow protectors on the market mainly protect elbow joints under the action of heat preservation and pressurization, and elbow joint position adjustment of LE patients is not targeted.

Second, foreign countries

1. The University of Kentucky (2009) proves that MWM has obvious therapeutic effect on LE through clinical observation tests, and the therapeutic significance can be derived from three aspects: (1) during MWM treatment, there was a 58% improvement in painless grip strength; (2) the results of study two: during MWM, 92% of subjects were able to perform previously painful movements, with a 46% improvement in pain-free grip strength immediately after treatment and a 10% improvement in stress-pain threshold immediately after treatment; (3) MWMs produce hypoalgesia (no painful grip and improvement in pressure-pain threshold) and physiological sympathetic excitation (opportunity for heart rate, blood pressure, cutaneous tone and vasomotor function); and Abbott (2001), MWM is considered a manual treatment strategy that uses forces that affect biomechanical joint alignment, thereby facilitating the required motion.

2. However, the foreign deficiency is similar to the domestic deficiency, and the alignment of the elbow joint is maintained by the patch for a long time, and the patch is not easy to popularize due to high cost, high operation difficulty, long time consumption, easy falling and allergy.
