The initial Q-Collar feasibility study (“Human Performance Study”) was completed in the Cincinnati Children’s Hospital Human Performance Laboratory and involved evaluation of monitored vital signs, biomechanics, cardiorespiratory capacity, postural control, dynamic stabilization, reactive index, concentration and cognition, memory, strength and power in a population of athletes showed no statistical effect of wearing a prototype version of the Q-Collar compared to a sham arm band. In addition, CBC, renal panel, and urinalysis tests were performed before and after exercise performed with the device. Blood and urine measures remained in normal ranges and were not disrupted beyond the expected physiologic response to exercise.
Cumulatively, the pre- and post-measures indicate that neurologic parameters of executive function, eye hand coordination, balance, memory and reaction times were unchanged following two hours of physical testing wearing the device. The results of this testing indicate that the Q-Collar is safe to use during maximal aerobic capacity and maximal power testing and has no impact on performance, strength or endurance.
