Wrist and Hand Pain

Wrist and Hand Pain: When the Discomfort May Originate from Above

The wrist and hand are structures characterized by high-precision movement. They allow us to grip, write, carry objects, and perform fine-motor activities, thanks to the coordination between muscles, tendons, joints, and the nervous system.

However, when pain, tingling, loss of strength, or unusual sensations occur in the hand, analysis is often limited solely to the area where the discomfort presents, forgetting that there is a direct connection with superior structures.

The neck, shoulder, and the entire pathway of the arm play a fundamental role in the function of the hand.

The Connection Between the Neck, Arm, Wrist, and Hand

The nerves that provide sensation and motor function to the hand originate primarily in the cervical spine and travel down the entire upper limb.

Therefore, an alteration in neck mobility, cervical muscle tension, postural issues, or irritation of the neural structures can influence the symptoms that manifest further down.

This can manifest as:

• Tingling in the fingers or hand

• Numbness

• Pain radiating down the arm

• Loss of strength

• Sensation of electric shock or pins and needles

• Discomfort when using the wrist

This does not always mean that the source of the problem is located directly in the wrist.

The Importance of Assessing the Entire Kinetic Chain

The proper function of the hand depends on the correct relationship between:

• Cervical spine

• Shoulder

• Scapula

• Arm

• Forearm

• Wrist

• Hand

If one area loses mobility, experiences increased tension, or changes how it distributes loads, another part may begin to compensate.

For example:

Sustained tension in the neck and shoulders can increase the load on the tissues of the arm and alter the way movement is transmitted to the wrist.

Consequently, treating only the painful area may temporarily relieve the symptom but fail to fully resolve its root cause.

The Nervous System and Hand Discomfort

In addition to muscles and joints, it is essential to assess the nervous system.

Nerves require mobility and space to properly transmit sensory and motor information.

When there is irritation or heightened sensitivity, sensations such as the following may occur:

• Burning sensation

• Electric shocks

• Lack of sensitivity / numbness

• Pain disproportionate to the stimulus

Therefore, a comprehensive assessment must include not only strength and mobility, but also the response of the nervous system.

Therapeutic Approach in Physiotherapy

Treatment will depend on the underlying cause, but may include:

• Manual therapy targeting the neck, shoulder, arm, forearm, and wrist

• Myofascial release

• Joint mobilization

• Neural mobilization (neurodynamics), where indicated

• Treatment of myofascial trigger points

• Therapeutic exercise to improve strength and motor control

• Movement re-education and ergonomic recommendations

• Techniques such as deep dry needling, advanced manual therapy, or invasive techniques, when clinically indicated
