14 Best Home Exercise for Wrist Drop

Exercise for wrist drop is an important part of your overall treatment program along with Medical and Physiotherapy Treatment.

Wrist drop, also known as radial nerve palsy, is a condition characterized by the inability to extend the wrist and fingers due to damage or compression of the radial nerve. Specific exercises to improve wrist drop typically involve a combination of stretching and strengthening movements to regain function and mobility in the affected wrist and hand.

Due to a radial nerve’s innervation of the extensor muscles of the wrist & digits, those whose radial nerve function has been compromised may not vigorously extend them. Therefore, when a patient attempts to bring an arm to the horizontal position, the arm, and hand hang unsteady in the flexion position. A wrist stays partially bent because of the opposing action of the flexor muscles of the forearm. Therefore, the extensor muscles in a posterior compartment remain paralyzed.

What is Wrist Drop?

The upper extremity’s hand and wrist have a significant amount of activity. So many daily activities depend on wrist function. The upper-limb, as well as wrist examination, was done in a structured format, which will allow to encourage the most suitable working diagnosis for therapy. The bilateral hand comparison could be helpful because it can be hard to diagnose hand and wrist abnormalities.

There are 3 variable degrees of nerve damage:

Neurapraxia: A 1st-degree injury, is the least serious classification.

Axonotmesis: This directs to a second-, third, or fourth-degree injury.

Neurotmesis: A last sense fifth-degree injury, which is the numerous severe form of nerve damage.

It is rare for radial nerve injury to happen on any site outside a humeral shaft or the proximal portion of the dorsomedial forearm. However, with more radial nerve palsy, a way of motor paralysis involves loss of wrist extension, thumb extension & abduction, as well as finger metacarpophalangeal joint extension. Higher radial nerve palsy typically doesn’t involve triceps function and elbow extension is preserved.

Proper flexor tendon tensioning needs wrist extension, which is strongly relaxed and serves as a functional deficiency following high radial nerve paralysis. More distal nerve damages involve a posterior interosseous nerve & result in low radial nerve palsy. Due to the retained extensor carpi radialis longus process, wrist extension is preserved with a radial deviation. However, the hand is startlingly awkward and clumsy in the absence of thumb extension, abduction, and finger metacarpophalangeal joint extension.

The radial nerve is one of the 3 nerves that travel down your arm, taking signs from your brain to your hand. The radial nerve allows your wrist to flex backward and regulates the movement of your tricep muscles.

Sleeping with your arm trapped under your body or being in another position that places tension on the radial nerve for an elongated period can induce it to get squeezed. Another common reason for the injury is the use of crutches since they can put a lot of stress on the nerve. Radial nerve constriction can also happen if you wear a tight bracelet or watch that restricts your wrist for an extended period.

You should consult your doctor if you suspect you might have wrist drop, to seek the proper diagnosis and treatment. A small analysis printed in the March 2014 case of the Journal of Korean Neurosurgical Society discovered that although the initial signs of this disease are serious and wrist drop’s recovery time may be several weeks, the disease generally has a good prognosis.

Causes:

There are numerous potential reasons for injuries to the radial nerve.

• fracturing the upper arm’s humerus bone
• positioning your upper arm uncomfortably while resting
• Pressure from bending your arm over the back of a chair
• Using crutches improperly
• Slipping on your arm
• wrist contractions that last for a long time
• The most frequent causes of radial nerve injuries are arm injuries, repetitive trauma to the arm, sports injuries, and occupational accidents. The radial nerve may be completely cut off depending on the degree of the injury. When the nerve is cut, it happens.
• Long-term nerve damage may occur through lead poisoning. Lead toxicity has the possibility to cause long-term harm to the body’s nervous system as a whole.
• One nerve may be impacted by specific health issues that have an effect on your entire body. Inflammation, fluid retention, and other symptoms which may indicate nerve compression can be pushed on by kidney disease and diabetes. The radial nerve and other nerves in your body might be affected by this.

Symptoms of wrist drop:

• A numbing sensation along the nerve’s route
• Weakness in the wrist, hand, or fingers
• Loss of action in the hand, fingers or wrist.
• The index and middle fingers, as well as the posterior hand, near your thumb, are typically affected by radial nerve injuries.
• Symptoms may have sharp or burning pain, as well as unique trends in your thumb and fingers. It is common to share numbness, tingling, and trouble straightening your arm. You can not spread or straighten your wrist and fingers. This is named “wrist drop” or “finger drop,” and it doesn’t happen in all cases.
• Radial nerve injury can cause pain, weakness, and loss of position in the wrist, hand, and fingers. A common time for this is radial nerve palsy.

Exercises for Treating Wrist Drop 

Mobilizing exercises 

Wrist flexion and extension

• Relax your forearm on the table with your hand over the edge of the table.
• Bend the wrist pointing the hand down towards the floor and then increase pointing towards the top.
• Use your additional hand to assist stretch your wrist so that your fingers are pointing up to the top and then down to the ground.

Ulnar and radial deviation (side to side)

• Hold your wrist and fingers straight. Keep your forearm still.
• Move your hand in the direction of your little finger and then in the direction of your thumb, with the action occurring at the wrist.

Strengthening exercise

Wrist flexion

• Relax your forearm on a table with the back of your hand facing down.
• Place the theraband in your hand. Gradually flex your wrist up as much as possible while resisting the motion with the additional hand.

Wrist extension

• Keep your elbow and forearm on a table and allow your wrist to drop over the edge.
• Place a band near your knuckles and grab onto the band under your hand.
• Extend your wrist as much as possible while resisting movement with the additional hand.

Weight transference

• Stand with both palms on a table.
• Gradually put your body weight on your wrists.
• Move your weight from side to side, slowly taking more weight and movement, as pain allows.

Wall push-up

Tips for Treatment & Recovery:

1. The Water Spout: Maintain a straight arm out in front of you, parallel to the ground. Then, while holding an empty cup in your outstretched hand, flip it over so that water is gushing out of it.
2. Figure Eight: Stand leaning forward with your natural hand on a worktop/back of a chair for support. Hang your involved arm in a figure-eight movement. Face your palm outward when your hand is closest to your torso. When your hand is most distant from your body, face your palm inward. 
3. Hide and Seek: Maintain your elbow out away from your side. Keep your arm at a ninety-degree angle with your palm facing up. While maintaining your elbow still, turn your forearm behind it. Once more with your palm facing the ceiling, position it behind your elbow. Rotate your head to look at your fingers.
4. Don’t Forget to Tip: Examine the involved side. As if receiving a backhanded tip, place your hand behind your back. You can crisscross your fingers.
5. The Water Pump: Keep hands in a bending position. Pump your hands in an up-and-down motion.
6. Table Stretch: Keep the back of your hand flat on the table and turn your entire body away.
7. Self-Massage: Massage the back of your hand in a circular movement. Depending on the side involved, the right hand should circle counter-clockwise, with the left hand circling clockwise.
