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) media roll, lateral glideb) lateral roll, lateral glidec) medial roll, medial glided) lateral roll, medial glide

Explanation:

For thumb flexion, the joint mobilization principles involve appropriate roll - glide combinations. When there is hypomobility (limited movement) in thumb flexion, the direction of roll and glide is based on the concave - convex rule. The metacarpophalangeal joint of the thumb (for flexion) follows the rule that if the moving surface is convex (as in some aspects of thumb joint movement for flexion), the roll and glide are in opposite directions. A lateral roll (in the context of thumb joint mechanics for flexion) and medial glide combination is appropriate to restore the normal arthrokinematics (joint movement mechanics) and increase the range of motion for flexion.

Answer:

d) Lateral roll, medial glide
