supraspinatus and infraspinatus exercises

[Guest guest]

Are there exercises to work both the supraspinatus and infraspinatus muscles? We

have suggested UWTM to our patient (case information to follow) but are there

any other exercises we can suggest? Would ESTEM help? Here's the case info...

History:

Cheyenne is in for CT scan to evaluate a chronic left forelimb lameness and

muscle atrophy on the right shoulder.

Physical Examination:

8 year 9 months, MN, Collie

Temperature: 100.4, Weight: 33.000 kg, 72.60 lb,

Appearance: Bright, Alert, and Responsive, Mucous Membranes: pink, Capillary

Refill Time: <2 sec. The heart and lungs were ausculted and sounded normal.

Primary Problem: Grade 2/5 lame on the right front leg. Severe muscle atrophy of

the supraspinatus and infraspinatus muscles on the right shoulder. The left

front leg is within normal limits. The neck palpates within normal limits. No

further abnormalities found.

Radiographic Findings:

CT evaluation of the cervical spine and both shoulders reveal severe

supraspinatus and infraspinatus atrophy on the right. There is no evidence of

spinal cord compression in the cervical spine. The left shoulder is within

normal limits.

Diagnosis:

Severe supraspinatus and infraspinatus muscle atrophy on the right. Strongly

suspect an injury to the suprascapular nerve on the right. No source of lame

left forelimb lameness was identified. Suggest underwater treadmill therapy to

maintain strength of the other muscles of both forelimbs.
