Which of the following is a common example of loss of coordination?

Loss of coordination refers to a lack of control over body movements, making it difficult for an individual to maintain balance and execute physical tasks smoothly. Stumbling is a clear indication of this loss of coordination, as it often occurs when a person has impaired motor skills and struggles to control their movements, typically seen in individuals who have consumed alcohol or other substances.

Excessive talking does not necessarily indicate a loss of coordination; it may simply reflect a change in behavior or mood. High energy can occur independently of coordination issues and may pertain to an animated or excited state without affecting motor skills. Clear speech typically suggests good coordination of the speech muscles and brain function, so it doesn't align with the concept of loss of coordination. Hence, stumbling serves as the most direct example of impaired physical coordination.
