Abstract

The strength of shoulder girdle muscles and R.O.M was measured isokinetically in fourteen patients who had suffered from frozen shoulder. All patients were tested monthly for 3 months.

The results obtained were as follows:

1) The increase in range of motion was significant (p<0.05) in forward flexion after 2 months, in abduction after 1 month, in internal rotation after 2 months, but not significant in external rotation in 3 months.

Three months later, range of motion reached 89.3% of normal in forward flexion, 79.9% of normal in abduction, 69.4% of normal in internal rotation, and 51.3% of normal in external rotation.

2) In 60 degree per second, the increase in muscle strength was significant (p<0.05) in forward flexion after 2 months, in abduction after 1 month, in internal rotation after 2 months, and in external rotation after 3 months.

Three months later, muscle strength reached 92.9% of normal in forward flexion, 90.4% of normal in abduction, 88.2% of normal in internal rotation, and 67% of normal in external rotation.

3) In 180 degree per second, the increase in muscle srength was significant (p<0.05) in forward flexion after 2 months, in abduction after 3 months, in internal rotation after 1 month, and in external rotation after 2 months.

Three months later, muscle strength reached 93.3% of normal in forward flexion, 59.5% of normal in abduction, 88.2% of normal in internal rotation, and 67% of normal in external rotation.

4) In slow speed test, the correlation between peak torque and range of motion was not significant for external rotation up to 2 months, but after 2 months, the correlation between peak torque and range of motion was highly significant in all shoulder joint motion, thus increased strength of shoulder girdle muscles seemed to accompany range of motion and subjective relief of pain.

5) According to above data, fast speed isokinetic resistive exercise of abductor and external rotator after 2 months, combined with heat therapy and active range of motion exercise seemed to acquire good therapeutic result.
