US 4,784,143 A · Method for correcting human gait by weighting of footwear

Abstract

A method for correcting human gait involving the application of weights to footwear so as to dynamically align and balance the foot during running or walking motion. Steps include the determination of fore-aft misalignment; the application of weight to the outside edge of the footwear if the misalignment is toe-out, or to the inside edge if the misalignment is toe-in; and iterative redetermination of fore-aft alignment while adding, removing or repositioning the weights upon the footwear until fore-aft alignment is achieved. Dynamic roll alignment may additionally be corrected by applying weight on the outside edge of footwear for pronation, or on the inside edge for supination, with iterative redetermination of dynamic roll alignment and corresponding adjustment of weight and location of previously positioned fore-aft alignment weight, so as to provide total foot alignment and balance. The foot having the greater fore-aft misalignment may be determined by the identification of the non-dominant foot, such foot being preferred for first correction.

Dependent claims

A method for correcting human gait by the weighting of footwear, comprising the following steps:

a. determination of any dynamic fore-aft misalignment with respect to the direction of movement, and whether said misalignment is toe-out or toe-in;
b. application of a weight to the footwear on the outside eage of said footwear if said dynamic fore-aft misalignment is toe-out, or on the inside edge of said footwear if said dynamic fore-aft misalignment is toe-in;
and
c. iterative redetermination of dynamic fore-aft alignment and further addition to, or removal of, weight at said outside edge of said footwear if said dynamic fore-aft misalignment is toe-out, or at said inside edge of said footwear if said dynamic fore-aft misalignment is toe-in, so as to result in dynamic fore-aft foot alignment.

A method for correcting human gait by the weighting of footwear, comprising the following steps:

a. determination of the non-dominant side of the body;
b. determination of any dynamic fore-aft misalignment, with respect to the direction of movement, on the foot on said non-dominant side of the body, and whether said misalignment is toe-in or toe-out;
c. application of an initial weight to the footwear at the metatarsal portion of the foot and on the outside edge of said footwear if said dynamic fore-aft alignment is toe-out, or on the inside edge of said footwear if said dynamic fore-aft alignment is toe-in;
d. iterative redetermination of dynamic fore-aft alignment, and further addition to, or removal of, or repositioning of weight at said outside edge of said footwear if said dynamic fore-aft alignment is toe-out, or at the inside edge of said footwear if said dynamic fore-aft alignment is toe-in;
so as to result in dynamic fore-aft foot alignment;
e. determination of any dynamic roll misalignment in the fore-aft aligned foot, and whether said dynamic roll misalignment is pronation or supination;
f. application of additional weight as follows:
for pronation, additional weight as follows:
edge of the footwear;
for supination, addition of weight on the inside edge of the footwear;
g. iterative redetermination of roll alignment and addition to, or removal of, weight added for roll alignment correction so as to achieve roll alignment, while adjusting the weight and location of the fore-aft alignment weight so as to maintain the fore-aft alignment of the foot;
and
h. repeat the process for the foot on the dominant side of the body.
