Nervous system lesions can cause wrist imbalance, leading to conditions like spasticity and contractures. Understanding muscle-tendon-joint interactions is key for surgical correction in neuromuscular disorders.
Area of Science:
- Neurology
- Biomechanics
- Reconstructive Surgery
Background:
- Central and peripheral nervous system lesions disrupt wrist muscle balance.
- Spasticity causes hyperactive wrist flexors, potentially leading to flexion contractures.
- C6 spinal cord injury and tetraplegia often involve motoneuron lesions affecting wrist deviation.

Muscles of the Forearm that Move the Hand and Fingers
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Muscles that Move the Forearm
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
