If 240 volts is applied (L1 to L2) to the circuit below, what voltage should you read across the start button.  Assume all devices are  in the state shown.

If the resistance of a circuit is 24 ohms and the current flowing in the circuit is 10 amperes, what voltage is being supplied to the circuit? 

Based on the 3 point pressure system, identify the affect compartment being unloaded by the knee orthosis pictured.  

Physical evaluation of a pediatric CP patient reveals an R1 of -5 (5 degrees PF) and a R2 of WNL (full range).  Select below the most likely posture of the tested ankle in midstance. 

Select below the recommended treatment for a Grade I-II sprain of the LCL. (HINT:  Gary Bedard explains in the Determination of Knee Center video how the knee goes into 7-11 degrees of valgus at full extension and at 25 degrees of flexion incurs a varus moment)

The GRAFO is effective at limiting ankle dorsiflexion and reducing knee flexion by controlling the amount of tibial advancement over the foot.  This essentially blocks which of the 4 rockers of gait?

A patient presents a prescription for bilateral Ground-Reaction AFOs.  Their MMT reveals fair (3/5) knee extensors and fair (3/5) ankle plantar flexors. What gait pattern will this patient would likely exhibit with orthoses?

Your patient is unable to abduct their left leg while side-lying during a manual muscle test of the gluteus medius.  Select below the most appropriate statement.

That Galeazzi Test is a clinical test useful in determining all of the following except. 

Excessive flexion and internal rotation of the hip are mechanisms of which type of dislocation?
