Abstract
Abstract A device and accompanying instrumentation measures involuntary tremor and unsteadiness of the human body when standing in an erect position upon the device. Novel construction and combination produces highly accurate readings in spite of difference in weights and weight distribution of the subject. Correlated data makes possible studies revealing learning potentials, brain damage, neuro-muscular responses, effect of diet and drugs, and aids in evaluation of the treatment of related syndromes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
An ataxiameter comprising: a pair of horizontal cantilever beams suspended from a common central support in horizontal alignment with each other; said cantilever beams being characterized by the complete absence of restraining means at the free ends thereof; a first means for positioning the heel portion of the foot of a human upon the first of said beams; a second means for positioning the ball portion of a foot of a human upon the second of said beams, said first means and said second means being mechanically independent of each other; electrical strain gauges positioned upon the surfaces of said beams at their fixed and at their free ends respectively; means for interconnecting said strain gauges; an electrical recording device; means for connecting said strain gauges to said recording device.
Claim 2
Dependent Claim
130 words
An ataxiameter comprising: a pair of horizontal cantilever beams suspended from a common central support in horizontal alignment with each other; said cantilever beams being characterized by the complete absence of restraining means at the free ends thereof; a first means for positioning the heel portion of the foot of a human upon the first of said beams; a second means for positioning the ball portion of a foot of a human upon the second of said beams, said first means and said second means being mechanically independent of each other; electrical strain gauges positioned upon the surfaces of said beams at their fixed and at their free ends respectively; means for interconnecting said strain gauges; an electrical recording device; means for connecting said strain gauges to said recording device.
Claim 3
Dependent Claim
39 words
The device of claim 1 in which said means for interconnecting said strain gauges comprises a Wheatstone bridge network; an electrical recording instrument connected across the legs of said bridge network; an electrical power supply connected to said network.
Claim 4
Dependent Claim
15 words
The device of claiM 2 including means for varying the intensity of said power supply.
Claim 5
Dependent Claim
155 words
An ataxiameter comprising: a central fixed section; a rear horizontal cantilever section having a fixed end and a free end, said fixed end being positioned on one side of said central fixed section; a forward horizontal cantilever section having a fixed end and a free end, said fixed end being positioned on the opposite side of said central fixed section; a first plate positioned above said rear section in contact with said free end of said section and adapted to receive the heel part of a human foot; a second plate positioned above said forward section in contact with said free end of said section and adapted to receive the ball part of a human foot; electrical strain gauges positioned upon opposite ends of said cantilever sections so as to be responsive to strains produced by the deflection of said sections; an electrical recording device; means for connecting said strain gauges to said recording device.
Claim 6
Dependent Claim
155 words
An ataxiameter comprising: a central fixed section; a rear horizontal cantilever section having a fixed end and a free end, said fixed end being positioned on one side of said central fixed section; a forward horizontal cantilever section having a fixed end and a free end, said fixed end being positioned on the opposite side of said central fixed section; a first plate positioned above said rear section in contact with said free end of said section and adapted to receive the heel part of a human foot; a second plate positioned above said forward section in contact with said free end of said section and adapted to receive the ball part of a human foot; electrical strain gauges positioned upon opposite ends of said cantilever sections so as to be responsive to strains produced by the deflection of said sections; an electrical recording device; means for connecting said strain gauges to said recording device.
Claim 7
Dependent Claim
39 words
The device of claim 4 in which said means for interconnecting said strain gauges comprises a Wheatstone bridge network; an electrical recording instrument connected across the legs of said bridge network; an electrical power supply connected to said network.
