PROSTHETIC CPM ACTUAL EXAM PAPER 2026
QUESTIONS WITH ANSWERS GRADED A+
◉ TT Bench Alignment. Answer: 5* socket flexion (+contracture)
5* socket adduction (or match sound)
Foot: 37mm posterior to midline (SACH) or 1/3 of foot (DR)
Foot: 12 mm inset to midlineder
◉ Info for Px Eval. Answer: Name, Age, DOB, Sex
Ht, Wt
Meds, comorbidities
Amp site/cause/date
ADLs/vocational/avocational
Goals!
Home status/environment
Work status/environment
PT/OT, assistive devices used
Current/previous px treatment
MMT, ROM
Sensation
Condition of residual limb
,Condition of contralateral/upper extremities
K-level/AMP
◉ K0. Answer: The patient does not have the ability or potential to
ambulate or transfer safely
◉ K1. Answer: Prosthesis for transfers or ambulation at fixed cadence;
household ambulator
◉ K2. Answer: Ability to traverse low level environmental barriers;
limited community ambulator, fixed cadence
◉ K3. Answer: Ambulation at variable cadence; prosthetic utilization
beyond simple locomotion; "unlimited" community ambulator, traverse
most environmental barriers
◉ K4. Answer: Exceeds basic ambulation skills, exhibiting high impact,
stress, or energy levels; child, active adult, or athlete.
◉ K1 feet. Answer: SACH, Single axis, safe
◉ K2 feet. Answer: Multiaxial, flexible keel
◉ K3-4. Answer: Dynamic response (also often multiaxial)
, With vertical shock
Shock & torque absorbers
◉ External power feet. Answer: K1-3, all cadence/terrain
Pros: propulsion, dorsi/plantarflexion
Cons: batteries/weight/cost/processing speed
◉ Single axis feet. Answer: Pros: inexpensive, durable
Cons: rigid forefoot, not energy efficient, not suitable for uneven
surfaces
◉ SACH feet. Answer: Pros: provides stability in early stance
Cons: DF stop increases knee hyperextesion
◉ Flexible keel. Answer: Pros: provides easy rollover, smooth transition
from heel strike to toe off, allows natural sagittal plane motion, reduces
socket foreces on residual limb, improves walking safety, reliable
Cons: limited push off, increased cost
◉ Multiaxial feet. Answer: Pros: Accommodates uneven terrain,
decreases stress on skin and prosthesis
Con: Increased weight/maintenance, cost
