Which intervention is most likely to reduce symptoms of plantar fasciitis when first waking each morning?

• A. Heel cup
• B. Rigid orthotics
• C. Low dye taping
• D. Dorsiflexion splint

Answer: (D)

Morning pain from plantar fasciitis comes from the plantar fascia being shortened and the calf–achilles complex tightening after a period of rest. A dorsiflexion night splint keeps the ankle slightly in dorsiflexion while you sleep, providing a gentle, continuous stretch to the plantar fascia and calves. This overnight stretch reduces the tendency for a sharp, painful pull when you take the first steps in the morning, addressing the underlying mechanism of morning symptoms.

Other options don’t address that overnight tightness as directly. A heel cup cushions the heel and can relieve pressure during the day, but it doesn’t lengthen the fascia overnight. Rigid orthotics support the arch during activity but don’t provide the sustained stretch needed during sleep. Low-dye taping offers daytime support but doesn’t maintain a prolonged stretch through the night.
