The Musculocutaneous nerve is a peripheral nerve that is responsible for innervating the muscles in the anterior compartment of the arm and providing sensory input to the skin on the lateral forearm.

It is important for physios to understand the anatomy and function of the Musculocutaneous nerve, as well as the potential injuries and treatment options associated with this nerve.


The Musculocutaneous nerve arises from the lateral cord of the brachial plexus, which is a network of nerves that originate from the cervical and thoracic spinal cord. It is composed of fibers from the fifth, sixth, and seventh cervical nerves. The Musculocutaneous nerve travels down the arm and pierces the Coracobrachialis muscle, then descends between the Biceps brachii and Brachialis muscles. It provides motor innervation to these muscles and sensory innervation to the skin on the lateral forearm.


The Musculocutaneous nerve is responsible for flexion of the elbow joint, as well as supination of the forearm. It innervates the Coracobrachialis, Biceps brachii, and Brachialis muscles, which are important for these movements.


The Musculocutaneous nerve branches into the lateral cutaneous nerve of the forearm, which provides sensory innervation to the lateral aspect of the forearm.


Injuries to the Musculocutaneous nerve can occur as a result of trauma, compression, or entrapment. These injuries can cause weakness or paralysis of the muscles innervated by the Musculocutaneous nerve, as well as sensory deficits in the lateral forearm.


Examination of the Musculocutaneous nerve includes a thorough history and physical examination. Patients may report weakness or numbness in the arm or forearm. Physical examination may reveal weakness in elbow flexion or supination, as well as sensory deficits in the lateral forearm.


Treatment for Musculocutaneous nerve injuries varies depending on the severity and underlying cause of the injury. Conservative treatment may include rest, immobilization, and physical therapy. Surgical intervention may be necessary in severe cases, such as when there is nerve compression or entrapment.

As a physiotherapist, understanding the anatomy and function of the Musculocutaneous nerve is crucial in providing effective treatment for patients with arm and forearm injuries. A thorough history and physical examination can aid in the diagnosis of Musculocutaneous nerve injuries, and appropriate treatment options can help patients achieve optimal recovery.

quickly learn about things that are relevant in the setting where I work

without spending hours researching and analyzing

papers for quality of research to see if something might apply where I work."

- Alyson Hackett

"I have found these updates helpful.

I find the content has a nice variability and covers conditions often seen in an out patient private practice

and therefore very relevant."

- Candace Goh

"Your weekly research update is facilitating me to

It is often so difficult to find time to read articles when you have your own practice.

Between seeing patients and running your practice it becomes difficult to make sure that you are up to date on the latest rehab techniques and new studies that's been done.


I used to spend hours

trying to find relevant articles that actually helps me to treat my patients better.


These updates makes it so easy and the best part is

you can apply what you read in your practice.


I really feel that it makes a huge difference in my practice and if i need to read the whole article it is right at my finger tips.

I love the fact that I can tell a patient I read this article about their injury and this is the latest an greatest new research about it.

They love it as well.


It is like breath of fresh air in my practice."
