Brachialis muscle is found at the upper arm. It flexes the joint of elbow while assisting the biceps all the way through the endeavor. This muscle originates in the lower half of the humerus’ front close to insertion of the deltoid muscle. However, this muscle doesn’t get involved in pronation and supination of the forearm because they are not inserted in the radius.
Brachialis is a Latin word which means “to the arm”. The muscle is greatly involved in the flexion of the elbow regardless to the grip someone is using while exercising. Thus, it is a very important muscle used in playing sports especially while grabbing or pulling. It also balances the elbow joint by collaborating with bicep brachii which is particularly significant for overhead movements like throwing handballs and volleyballs.
Exercises for the brachialis muscles ought to give a larger appearance to the biceps and makes the muscles stronger which enhances the strength overall. When searching for such exercises that will increase the brachialis strength, experts recommend the exercises that focus on bicep set. There are many exercises that can help you get those results; some of them include hammer curls, upside down curls and thumbs up curls.
Brachial plexus communicate between shoulders and spine and they could get injured while playing contact sports and the patient may experience a lot of pain. While stretched nerves heal themselves, the torn ones require therapy. The symptoms of a tear vary and are determined by location and severity.

When the strains are less, the sufferer experiences electric shocks in the arm and numbness and weakening of the arm is also experienced. The disability and weakening becomes permanent when the injury is major and medical attention will be required as soon as possible.
The injury to the brachial plexus could be due to a number of ways. These include trauma like accidents, bullet wounds and animal bites etc. Contact sports also stretch the brachialis nerves when the players collide. Other than that, difficult births and problem in childbirth can injure both lower body and upper body nerves of the baby.
Diagnosis and Treatment
A number of tests are used to determine the severity and extent of the injury to the Brachialis muscle. The two of these preliminary tests are magnetic resonance imaging and electromyography. The former uses radio waves and magnetic force to determine the damage to the muscles and severity of the injury to the brachial plexus. It also helps in verifying if the nerves have disengaged from the spinal cord. The latter, electromyography, is done by inserting a needle from skin to muscle and after it’s done, the patient is asked to contract that muscle. It generates electrical activity and gives information about the muscle’s response on stimulation of the nerve. It may be painful, not necessarily uncomfortable, but it successfully determines the nerves’ health using the movement of muscles.
The pain of Brachialis muscle tear is overwhelming. The first step towards treatment is acknowledging the pain and using anticonvulsants and antidepressants to ease it. Also, Transcutaneous Electrical Nerve Stimulation – a device that uses electrodes to relieve the pain – could be used. One other way that doctors use is transferring the muscles from some other body part to the arm in case when the arm muscles are getting deteriorated. In some cases when the muscles are not torn, they heal themselves but sometimes it leaves scar tissues that need to be removed to make the nerves work; that calls for a nerve surgery.
