The NeckSpring was developed to provide an external force for exercising the neck.  Exercising the neck with an external force had been found from experiments and researchers to be more effective compared to exercising without additional force.  However, the external force used are commonly improvised gym equipment (such as a pulley with or attachments to gym weights), holding barbell weights over the head or by using available stretching devices such as an elastic band.  The NeckSpring provdes the necessary external force to exercise the neck in a compact, simple to use apparatus where the hazarous use of a variety of ackward and improvised devices are not necessary.  People who use the NeckSpring have found benefits from it's use.

A research  study reports that women with chronic neck pain who used elastic bands to exercise their necks brought a significant level of improvement (as much as four time more) than those doing similar neck-stretching exercises without the additional force.  Still, basic non-resistance stretching was about three times more effective than doing no specific neck exercises.  This was reported in The Journal of the American Medical Association.

An experiment involving 36 football players showed that exercising with an external force had significantly better results than without it.  Of the 36 football palyers, one-third of the players exercised by jogging and sprinting,  another third exercised their neck by exerting force against the resistance of their own hands (isometric exercise) and the last third exercised their neck, with an improvised device, against the resistance of barbell weights (isokinetc exercise).  It was found from this experiment that the group that did isokinetic exercises (with the resistive force of weights) increased their neck circumference by an average of 1.25 inches.  The group that did isometric exercises (with resistitive force of their own strength) increased their neck circumference by 0.375 inches and the group who jogged and not used any sources of external force had no significant increase.  The results of this experiment were reported in an article entitled "Helping Athletes Avoid Neck Injuries" by John H. Bland, M.D. in The Journal of Musculoskeletal Medicine.

A Physical Therapist who has personally used the NeckSpring and also uses the NeckSpring with patients and staff in her office stated that the NeckSpring is the first device to offer cervical strengthening in a quick and effective manner.  Typically cervical strengthening exercises are boring and cumbersome but the NeckSpring changed that.
