Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
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 radialis,...
Muscles that Move the Forearm01:16

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
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...
Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Assessment of radial pulse01:11

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Summary
This summary is machine-generated.

The forearm and finger rolling tests can detect upper motor neuron lesions. The finger rolling test is more sensitive, and both tests show high specificity for focal brain lesions.

Area of Science:

  • Neurology
  • Clinical Neurophysiology

Background:

  • Detecting subtle upper motor neuron lesions is crucial in clinical neurology.
  • Limited studies have quantified the diagnostic accuracy of common clinical tests for these lesions.

Purpose of the Study:

  • To evaluate the sensitivity and specificity of the forearm rolling test and the finger rolling test in identifying upper motor neuron lesions.
  • To compare the diagnostic utility of these two tests against traditional neurological assessments.

Main Methods:

  • The study involved performing forearm rolling and finger rolling tests on patients with suspected focal brain lesions.
  • Sensitivity and specificity were calculated by comparing test results with the presence of a confirmed focal brain lesion.

Main Results:

  • Both forearm and finger rolling tests demonstrated higher abnormality rates in patients with focal brain lesions compared to assessments of power, tone, and reflexes.
  • The finger rolling test exhibited greater sensitivity than the forearm rolling test.
  • Abnormal findings in both rolling tests were highly specific for the presence of a focal brain lesion.

Conclusions:

  • Forearm and finger rolling tests are simple, rapid clinical tools effective in detecting upper motor neuron dysfunction.
  • The finger rolling test offers superior sensitivity, while both tests provide high specificity for diagnosing focal brain lesions.
