The ECR & ECU are involved in tennis elbow injury. It becomes very tender to the touch on the elbow (lateral epicondylitis), which is a condition when the outer portion of the elbow becomes sore and tender. It is commonly caused by over use.
The extensor carpi radialis longus is one of the five main muscles that control movements at the wrist. This muscle, starts on the lateral side of the humerus, and attaches to the base of the second metacarpal bone aka index finger.
The extensor digiti minimi originates from the lateral epicondyle of the humerus, or the outer edge of the elbow if the palm is facing up, in the anatomical position. It runs along the back of the back of the arm to the wrist and past the wrist to the proximal phalanx V, or the bone between the genital knuckle and first bend of the finger of the little finger.
RX is always ice 30 minutes 2 – 3 x a day on the painful area. Take anti-inflammatory meds, stretch, and tape the shin and arch before any physical activity.
Flexor Carpi Ulnaris and Flexor Carpi Radialis Tendinitis
Pain: Pain, tenderness, swelling, warmth, or redness on the underside of the wrist.
Pain that gets worse when bending the wrist, especially against resistance or when turning the palm down against resistance. It is mostly localized with some pain developing on the lateral portion of the wrist.
Pain with gripping.
Limited motion of the wrist.
Crackling sound (crepitation) when the tendon or wrist is moved or touched.
Hammer Curls engage the Brachioradialis and creates that full look with the biceps when flexed.
Brachioradialis pain pattern extends from the anterior elbow joint down to the wrist. It tends to spasm when inflamed or fatigued after a hard workout.
Action: The brachioradialis flexes the forearm at the elbow and pronation and supination of the wrist and forearm. It also assists in flexion with the Biceps Brachii and Brachialis. If you perform hammer db curls, it engages the Brachioradialis muscle. If over trained or inflamed, it becomes difficult to wash your hair and spasms at the sight of the muscle when flexing the biceps and is very tender to the touch. The pain usually stay local to the muscle.
RX: Ice the area of pain and inflammation, take anti-inflammatory, rest.
