Which of the following actions can help accommodate a client with plantar flexion difficulty?

Using a foot board to support the foot is the appropriate action to accommodate a client with plantar flexion difficulty. Plantar flexion refers to the movement that decreases the angle between the foot and the lower leg, such as standing on tiptoes. Clients with difficulty in this movement may struggle to maintain proper positioning or stability.

A foot board can help by providing external support to keep the foot in a neutral or slightly elevated position, thereby supporting proper foot alignment and reducing any strain on the ankle. This support encourages comfort and may prevent further complications or discomfort during movement or rehabilitation.

The other actions do not effectively address the needs of a client with plantar flexion difficulties. Keeping their feet flat on the floor might not provide the necessary support and could lead to discomfort. Encouraging walking barefoot may not help maintain stability or avoid injury, especially if the client struggles with balance. Providing ankle weights for resistance can be counterproductive as it may further challenge the client's ability to control their movements, leading to increased difficulty rather than assistance.
