Question

which of the following is true regarding circumduction gait? (maca)
weakness of hamstrings
contracture of hamstring
contracture of gastroc and soleus
weakness of posterior tibialis
question 32 (mandatory) (2 points)

Explanation:

Circumduction gait (also known as steppage gait or high - stepping gait) is often associated with weakness of the posterior tibialis muscle. The posterior tibialis muscle is important for foot inversion and maintaining the medial arch of the foot. When it is weak, the foot drops (foot drop), and the patient has to lift the leg higher (circumduct) to clear the ground during walking. Weakness of hamstrings is more related to problems with knee flexion and hip extension during gait but not the typical circumduction gait. Contracture of hamstring would limit knee flexion and hip extension, presenting with a different gait pattern. Contracture of gastrocnemius and soleus (calf muscles) leads to equinus deformity (toe - walking or difficulty in dorsiflexion), not circumduction gait.

Answer:

D. Weakness of posterior tibialis
