Which condition is indicated by an inability to move one or more limbs?

The condition indicated by an inability to move one or more limbs is paralysis. Paralysis refers to the loss of muscle function in one or more limbs and can result from various causes, such as damage to the nervous system, brain injury, stroke, or spinal cord injuries. This condition can be classified into different types, including complete paralysis, where there is no movement at all, and partial paralysis, which allows for some movement but not full control.

In contrast, paresis relates to a weakness of voluntary movement or partial paralysis, not a complete inability to move; neuropathy refers to nerve damage that can cause pain, weakness, and sensory issues but doesn't necessarily result in complete loss of movement; muscle strain involves tearing or overstretching of muscles, typically resulting in pain and limitations, but not a complete inability to move the affected limb. Hence, paralysis distinctly represents the inability to move limbs, making it the correct answer.
