Abstract:
The diagnosis of functional paresis is evoked when a patient presents with symptoms and signs incompatible with current anatomical and physiological knowledge. A broad assessment, including imaging and motor evoked potentials at rest, remains necessary; the rate of false diagnosis being estimated at 4%. The mechanisms of hysteria remain still dubious but various studies suggest that functional paresis is different from simulation by conscious, voluntary inhibition. The long-term prognosis is bad. The treatment includes cognitive-behavioral therapy and rehabilitation to develop a positive attitude.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
