Reflex hammer with sensors

A system includes:

• a deep tendon reflex hammer comprising:
• a handle;
• a head coupled to the handle;
• a bumper supported by a first end of the head and adapted to be used to strike a patient tendon;
• a pressure sensor embedded in material of the bumper and adapted to generate pressure data in response to and representative of pressure encountered by the bumper;
• a first accelerometer coupled to generate head acceleration data in response to movement of the head, wherein the first accelerometer comprises a six degree of freedom accelerometer and wherein the head acceleration data and pressure data is representative of magnitude and angle of approach to strike and magnitude and angle of strike rebound with respect to the patient tendon representative of a validity of the strike;
• and
• first circuitry to capture the pressure data and head acceleration data and coordinate the data to a synchronization pulse from which strike magnitude and angle and rebound magnitude and angle is calculatable to determine a valid tendon strike;
• and
• a second device comprising:
• a housing adapted to be coupled to a patient limb;
• a second accelerometer supported by the housing to generate limb acceleration data;
• and
• second circuitry to capture the limb acceleration data and coordinate the data to the synchronization pulse, wherein the generated and captured data enables deep tendon reflex assessment, and wherein an acceptable strike is determined based the pressure data and the head acceleration data.
