Obscure Shoulder Pain with Arm Weakness in the Morning

A patient presented with left shoulder pain that presented primarily in the morning. For the past two weeks, he has experienced left anterior neck/shoulder pain and significant left arm weakness in the morning as well as an ache of his left pectoral region. He was not able to identify any motion that amplified or releived his symptoms. When asked to identify the most significant region of pain he pointed to the anterior superior border of the scapula.
1. Visual assessment
· Hypertrophy of the left levator scapula
2. Functional Motion Screen
· Decreased ROM of R cervical rotation with extension (asymmetrical to L motion)
· Full L shoulder abduction indicated compensation pattern and decreased axis of rotation.
3. Strength Assessment
· Infraspinatus and Supraspinatus weakness noted with resistance. Pain replication of anterior shoulder noted with infraspinatus resistance.
4. Palpation Assessment
· Tissue texture and tension consistent with adhesion of the infraspinatus (superior fibers) and supraspinatus (medial fibers at the levator scapula/supraspinatus junction.
· Tissue texure and tension consistent with adhesion of the omohyoid with decreased relative motion of the brachial plexus.
5. Treatment
· ART protocols to restore relative motion of the brachial plexus with the omohyoid and treatment of noted structures noted in palpation assessment.
The patient reported that this treatment replicated the exact symptoms that were described.
6. Retest of functional motion
· Unremarkable motion with R cervical rotation with extension
· Strength increase with non-painful with resistance of infraspinatus and supraspinatus
· Increased axis of rotation with full abduction
7. Impression
It is possible that a rotator cuff dysfunction has resulted in the hypertrophy of the levator scapula with a chronic compensation pattern. It’s hard to tell whether there was increased load of the omohyoid or this issue is altogether unrelated. Considering that this issue has only been symptomatic over the last two weeks it’s hard to tell. What’s most important to me is the symptom reproduction with ART treatment with decreased tension of the brachial plexus with treatment.
I will see this patient in approximately two days. I look forward to his report of his morning symptoms.
