Atonic

In medicine, 'atonic' describes the lack of normal muscle tone or the absence of muscular strength and responsiveness. It signifies a state of flaccidity, limpness, and reduced resistance to movement. This condition can result from various factors, including nerve damage, muscle disorders, or certain medical conditions. It's characterized by a diminished ability of muscles to contract effectively and maintain posture, often leading to weakness and difficulty in performing voluntary movements. The term is also used figuratively to describe a lack of energy, vitality, or enthusiasm in a non-medical context, such as an 'atonic' political campaign. The term can extend to any situation lacking tone or tension.
