Deltoid Muscle Strain
An injured deltoid muscle can cause shoulder pain at the front/ side or back of the shoulder.
What is the Deltoid Muscle ?
The deltoid muscle is the big muscle on the shoulder. It has three parts - the front (anterior), middle and back (posterior). The muscle lifts the arm up sideways. The front part helps to lift the arm up forwards (flexion) and the back part helps to lift the arm up backwards (extension).
Symptoms of a deltoid rupture include :
A sudden pain in the muscle at the front of the shoulder.
Pain when you lift your arm from your side to the front keeping it straight against resistance.
Pain when you lift your arm from your side up sideways against resistance.
Tenderness and swelling where the muscle is torn.
Grade 1: What does it feel like ?
You might have tightness in the muscles.
You may be able to use your arms properly or do press ups easily.
You probably won't have much swelling.
Trying to lift your arm up sideways or to the front or back of the body probably won't produce a lot of pain.
What can the athlete do ?
Apply ice for the first 24 hours (15 mins at a time) then heat.
Light exercises - 4 sets of 10 repetitions 3 times a week (for example).
Gradually build up the weight to strengthen the muscles.
The athlete should ease down on training for a week or two but it is unlikely they need to stop unless they are getting pain.
What can a Sports Injury Specialist or Doctor do ?
Use sports massage techniques to speed up recovery (very important).
Use ultrasound and electrical stimulation.
Prescribe a rehabilitation programme.
