Position

of the hip & knee in the follow through are the same as in execution

phase

, however they are now isometrically contracting.Slide22

See shoulder joint & girdle slides of execution phase. There

is no change in joint movement going into follow through.

Reference elbow joint slide of execution phase for follow through as well.

There is just further extension of the dominant elbow joint. Slide23

MOST COMMON PATHOLOGIES OCCURING FROM FREE THROW

3 very closely related pathologies:

Shoulder Impingement-

space between acromion & rotator cuff tendons is narrowed when arm is

raised,

causing the tendons to be

pinched or impinged.

Rotator Cuff Tendonitis- tendons become irritated or rubbed from repetitive lifting or overhead use.

Bursitis- bursa becomes inflamed, which causes it to swell and fill with more fluid (usually accompanies rotator cuff tendonitis)Slide25

symptoms

Sudden pain and stiffness when arm is lifted

May also have pain when arm is lowered from elevated position

Radiating pain from front of shoulder to side of arm

Pain at night

Loss of strength & motion

Difficulty with motions behind the back such as buttoning or zipping. Slide26

Treatment:

Considering patient age, activity level, & general health

Before resorting to surgery, a physician may prescribe:

Rest

Non-steroidal anti-inflammatory medication

Physical therapy

Cortisone injection

If none of these are effective, the patient and orthopedist may decide on arthroscopy.
