Common Wrists / Hand Injuries

FlexEx can be useful in combating and treating many of the following hand and wrist injuries.

Carpal Tunnel Syndrome

Carpal tunnel syndrome is pressure on the median nerve – the nerve in the wrist that supplies feeling and movement to parts of the hand. It can lead to numbness, tingling, weakness, or muscle damage in the hand and fingers.

The median nerve provides feeling and movement to the “thumb side” of the hand (the palm, thumb, index finger, middle finger, and thumb side of the ring finger). The area in your wrist where the nerve enters the hand is called the carpal tunnel. This tunnel is normally narrow, so any swelling can pinch the nerve and cause pain, numbness, tingling or weakness. This is called carpal tunnel syndrome, and can be relieved and rehabilitated using the FlexEx.

Who is most likely to get carpal tunnel syndrome?

People most at risk are those with jobs or activities that involve repetitive finger use, especially those associated with high force, long-term use, extreme wrist motions, and vibration.

Symptoms

Numbness in fingers (thumb, index, middle)
Tingling sensation, especially at night
Waking up due to wrist discomfort
Wrist curled during sleep worsens it

These nighttime symptoms are often the first reported symptoms. Shaking the hands helps relieve symptoms in the early stage of the condition

5 out of 5 stars - great exerciser

"I had surgery on my thumb joint, wrist and carpaltunnel on the nerve going up my thumb. After 6 weeks in a cast, I had lost range of motion in my thumb and the extension of the other four fingers.. They had been in the relaxed position for so long, it hurt to open my hand all the way. I also had no thumb pinching ability. So, this exerciser really helped. I would use it while watching TV, hardly being aware I was exercising. I also carried the band in my purse. Great little helper!"

DeQuervain’s Tenosynovitis

Tenosynovitis implies inflammation of a tendon and its enveloping sheath; deQuervain’s tenosynovitis is a specific type of this entity which involves the tendons of two specific muscles on the thumb side of the hand – the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These muscles are located in the forearm and their tendons travel across the wrist (through a “tunnel” termed the first dorsal compartment) on the thumb side to produce movement of the thumb. The walls of the affected tendon sheaths (basically protective coverings for the tendons) become thickened and inflamed, causing the symptoms described in the next section. The condition is 10 times more common in women, more often arises in the dominant hand, and usually occurs between the ages of 35 and 55.

Signs and Symptoms

Pain develops gradually over the radial styloid (forearm bone area) when using the thumb of the affected hand.
Pain typically worsens over weeks or months.
Difficulties with gripping and pinching are common.

In severe cases, the hand may be too painful to use.

Pain can radiate into the thumb, forearm, or shoulder.The affected area often shows thickening and tenderness.

Finkelstein’s test is used for diagnosis:

Patient grasps the thumb with other fingers and pulls it toward the small finger.
Sharp pain over the radial styloid confirms possible de Quervain’s tenosynovitis.

Condition should be differentiated from arthritis at the base of the thumb.
Without treatment, fibrosis in the tendon sheath may develop, leading to limited motion similar to trigger finger.
Ultrasound can confirm the diagnosis and monitor treatment progress.

Possible Causes

The exact cause of de Quervain’s tenosynovitis is unknown.
Overuse of the thumb and wrist (excessive, repetitive gripping and grasping) may contribute.
Overuse can lead to thickening of tissues in the compartment housing the APL and EPB tendons.
Reported in people with certain occupations or hobbies:

Bricklayers
Sewing workers
Piano players
Fly fishermen
Golfers

May also be linked to acute injury to the area:

Direct blow to the forearm or wrist
Falling on the thumb

Most cases are linked to chronic repetitive stress rather than a single injury.

5 out of 5 stars - goodbye tennis elbow

   What a great, simple invention. As a competitive tennis player, using the finger exercise bands relieved my annoying, debilitating tennis elbow in short order and has kept it away for a long time. Also works for golfers who like to hold the club too tightly and therefore suffer the same pain. Strongly recommend.

Tennis Elbow

Tennis or Elbow, or lateral epicondylitis, is the probably one of the most, if not the most common injury in individuals that require medical attention for elbow pain. It is not know what exactly causes tennis elbow , however, it is thought to be due to small tears of the tendons that attach forearm muscles to the arm bone at the elbow joint. Treatment of tennis elbow can often be frustrating for individuals who suffer from this ailment, but exercises with the FlexEx can help your symptoms.

Golfer's Elbow

Golfer's elbow is a condition that causes pain where the tendons of your forearm muscles attach to the bony bump on the inside of your elbow. The pain might spread into your forearm and wrist.

Golfer's elbow is similar to tennis elbow, which occurs on the outside of the elbow. It's not limited to golfers. Tennis players and others who repeatedly use their wrists or clench their fingers also can develop golfer's elbow.

The pain of golfer's elbow doesn't have to keep you off the course or away from your favorite activities. Rest and appropriate treatment can get you back into the swing of things.

Causes

Repeated wrist and finger strain
Forceful wrist or finger motions
Improper lifting, throwing, or hitting
Poor warm-up or conditioning

5 out of 5 stars - Ease of use- alleviates arthritic pain

This device has been immensely helpful with alleviating arthiritic pain. There are no complicated instructions to the use of the device, which makes easy to use. I highly recommend this product for anyone suffering from arthritis, or trying to increase strength/ grip in your hand(s).

Arthritis of the Hand

The hand and wrist have multiple small joints that work together to produce motion, including the fine motion needed to thread a needle or tie a shoelace. When the joints are affected by arthritis, activities of daily living can be difficult. Arthritis can occur in many areas of the hand and wrist and can have more than one cause.

Over time, if the arthritis is not treated, the bones that make up the joint can lose their normal shape. This causes more pain and further limits motion. However, using the FlexEx Hand Exerciser can help eliminate and relieve Hand Arthritis symptoms.
