Question

tommy, a 27 year old tennis player complains of pain and inability to flex his right thumb. performing which of the following joint mobilizations will most likely resolve this hypomobility?
a) lateral roll, medial glide
b) lateral roll, lateral glide
c) media roll, lateral glide
d) medial roll, medial glide

Explanation:

When dealing with joint hypomobility and aiming to improve flexion (in this case, of the thumb), the principles of joint mobilization based on the concave - convex rule are considered. For a convex joint surface moving on a concave one (which is relevant in thumb joint mechanics for flexion), a roll and glide in opposite directions is beneficial. A lateral roll (convex movement) with a medial glide (opposite direction) helps in restoring the normal arthrokinematics for flexion.

Answer:

A. Lateral roll, medial glide
