What is a likely impact of having strange motions in the finger and thumb joint on a client's functional ability?

Having strange motions in the finger and thumb joints can significantly impact a person's functional ability in various daily activities. The correct choice highlights the difficulties that may arise in tasks that require fine motor skills, such as dressing and feeding.

Fine motor skills, which involve the coordination of small muscles in the hands and fingers, are essential for activities that require precision and dexterity. If a client experiences irregular movements in their finger and thumb joints, it can hinder their ability to perform these tasks effectively. For example, dressing involves manipulating buttons, zippers, and fabric, while feeding requires accurately using utensils. In both cases, the functionality of the fingers and thumbs is crucial.

This type of impairment would not significantly affect larger gross motor skills such as the ability to climb stairs, walk, or maintain balance, which involve different muscle groups and coordination levels. Overall, the correct answer emphasizes the connection between hand function and independence in daily living activities.
