What condition is characterized by abnormal muscle tension resulting in restrictions of movement?

• A. Contracture
• B. Syncope
• C. Phobia
• D. Alopecia

Answer: (A)

The condition characterized by abnormal muscle tension that leads to restrictions of movement is contracture. Contractures occur when muscles, tendons, or other tissues shorten or tighten, which can limit mobility in the affected joints and muscles. This often results from prolonged immobility, neurological conditions, or severe injuries where normal movement patterns are disrupted.

In contrast, syncope refers to a temporary loss of consciousness, typically caused by a drop in blood flow to the brain, and is not related to muscle tension or movement restrictions. Phobia is an intense, irrational fear of a specific object or situation and also does not pertain to muscle function. Alopecia is the loss of hair from the scalp or other parts of the body and is unrelated to muscle tension or movement. Understanding contractures is vital in nursing care, particularly in preventing complications for individuals with limited mobility.
