When a Medical Massage clinic starts to deliver stable clinical results from patient to patient, it attracts more and more difficult cases. Patients start to see the clinic as a place to get the ultimate solution for their pain and suffering while everyone else has failed. We see this on a daily basis in our clinic in Phoenix, as well as in clinics associated with SOMI but located in different cities, including San Antonio, Colorado Springs and Los Angeles.
MEDICAL MASSAGE vs. ERB’S PALSY
Here is an example to illustrate this phenomenon: Four months ago, we had a very unusual case in our clinic. The patient was referred to us by her friend. Two days prior to her first appointment, she woke up and she couldn’t lift her right arm. The patient is a hairdresser, and she was forced to stop working while looking for help. The video below shows the initial clinical picture.
As you can see in the video, the patient lost active abduction and flexion and had weakened extension. However, she didn’t have any pain, numbness, tingling or burning sensations. In other words, there were not any abnormalities in the sensory innervation of the right shoulder and neck besides a sudden loss of function. While looking carefully at the video, you may have noticed that the patient could lift her right upper extremity up 20-30 degrees with complete loss of further abduction and flexion. Thus, her supraspinatus muscle, which is supposed to initiate movement, was functioning, but the patient completely lost function of the right deltoid muscle, which supports further movements.
Technically speaking, the clinical picture the patient exhibited was of Erb’s Palsy, but the complete absence of sensory deficit was really puzzling. The most common cause of Erb’s Palsy is damage to the brachial plexus of a newborn during delivery if the child passes through the birth canal arm first. In such a case, the obstetrician is forced to assist birth using the child’s arm as leverage. It causes Erb’s Palsy after the delivery, and to different degrees it may remain for the rest of the child’s life.
Another cause of Erb’s Palsy is compression of the spinal nerve by the disk at the C5-C6 level or compression of the brachial plexus between the anterior scalene and scalene medius muscles. Overall, Axillary Nerve Neuralgia is only 6% of all brachial plexus irritations by ASM (Loukas et al., 2009). However, in all these cases the patient MUST exhibit sensory abnormalities (pain, numbness, tingling, etc.) in the neck and/or shoulder. This wasn’t the case for this patient. She only lost function.
We suggested to the patient that she see a neurologist first, and he was equally puzzled. A nerve conduction study was done, and the cervical MRI didn’t reveal any severe spinal stenosis as a result of disk protrusion. The neurologist decided to use a facet joint injection in the neck and sent the patient to the PT, where her neck and right shoulder were worked on. All of that was unsuccessful, and the patient was greatly frustrated when the neurologist told her that there was a great chance she would have these symptoms for the rest of her life.
The patient came back to our clinic with the same symptoms and very depressed. Since she didn’t exhibit any other symptoms besides the lost function, we addressed the posterior neck (paravertebrals), the anterior neck (anterior scalene muscle) and the deltoid muscle itself. After five sessions, we got a very modest improvement which you can see in the video below. The active abduction and flexion increased slightly.
Something was definitely wrong with the therapy, since we realized that we were knocking on the same door people before us were trying to open. We needed a change in the treatment strategy. Since motor function of the deltoid muscle is supported by the axillary nerve, we decided to work along the entire pathway of the axillary nerve, including the axilla and posterior humerus. The patient came back two days after the session with a new treatment strategy. The video below illustrates what we got in just one (!) session.
Notice that she had excellent progress, but she could do full active movement only one time, and then the muscle refused to cooperate with her even with a second attempt to repeat the same movement. It meant that our treatment released the initial trigger of nerve irritation, but the muscle was very weak and didn’t have enough power to support repetitions.
We sent the patient to the swimming pool to do light repetitive exercise with the shoulder submerged under the water to increase muscle mass without jeopardizing the inflamed nerve. The patient and we were greatly excited by the results of the first session. In three more sessions, she had complete restoration of function and muscle mass and fully returned to her work. The video below illustrates the final results.
LESSONS
- Medical Massage has enormous clinical potential, but therapists must understand several basic rules: find the initial trigger of somatic pathology by knocking on all possible doors; the trigger is frequently hidden in what seems like completely unrelated places; the therapist shouldn’t give up and should always change the treatment strategy if therapy doesn’t show a positive dynamic.
While everyone, including us, initially concentrated on the most obvious places of axillary nerve irritation, such as the posterior and anterior neck, the real trigger was in the deltoid muscle itself. The PT and we worked on the deltoid muscle, but all of us focused on the origin of its innervation in the neck.
- We constantly stress to students that everything in Medical Massage is precision. If a therapist is 1/3 of an inch in an incorrect position, he or she addresses unrelated tissue. This patient is an excellent example. Let’s reconstruct what happened to this patient with the help of Fig. 1, which shows the pathway of the axillary nerve on the posterior shoulder.
Fig. 1. Axillary nerve on the right posterior shoulder Immediately after getting on the posterior shoulder just below the humeral head and under the deltoid muscle, the axillary nerve splits into anterior and posterior branches. The posterior branch goes backward and innervates the teres minor muscle, and it is unrelated to our case. The anterior branch goes forward and gives further deeper motor branches to the deltoid muscle, which penetrate the muscle and control its function, and more superficial branches, which innervate the skin over the shoulder.
The blue bar indicates part of the axillary nerve before it branches out. If irritation of the axillary nerve happens on any part of the nerve from this area all the way up to its origin from the spinal cord, the patient WILL exhibit loss of function (muscle weakness) AND sensory abnormalities: pain, pins and needles, burning pain, numbness, etc.
If the deltoid muscle gets tense, it may irritate the axillary nerve, which is just under it. For our patient, it happened because of her work as a hairdresser, in which she holds both arms in the air by isometrically contracting the deltoid muscles.
In Fig. 1, the violet color bar indicates the cutaneous branch and the green bar indicates the motor branch. If the tense deltoid compresses both branches, the patient will again exhibit loss of function AND sensory symptoms. If the deltoid muscle selectively compresses the motor nerves of the anterior branch (blue bar), which need to penetrate muscle to support its contractions, the patient will have only symptoms of lost function WITHOUT pain or any other sensory symptoms.
- The treatment which made the immediate difference for this patient targeted the inner surface of the deltoid muscle just below the head of the humerus, and it was done using posterior access through the axilla. It has to be done correctly without any excessive pressure because of the axillary nerve on the bone and the nearby circumflex artery.
- If this patient hadn’t had access to Medical Massage, she would have faced the prospect of a long recovery with likely development of scarification in the joint capsule (adhesive capsulitis), or, as the neurologist suggested, she would have had the same or residual symptoms for the rest of her life.
