and one or a plurality of crutches to provide support over the surface to the gait device, each of said one or a plurality of crutches comprising a locomotion facilitator to enhance locomotion of that crutch over the surface and a mechanism to modify the locomotion of that crutch over the surface. ### Claim 2 (depends on 1) The system of claim 1, wherein the locomotion facilitator comprises a wheel. ### Claim 3 (depends on 1) The system of claim 1, wherein the locomotion facilitator is retractable. ### Claim 4 (depends on 1) The system of claim 1, wherein the locomotion facilitator comprises a motor. ### Claim 5 (depends on 1) The system of claim 1, wherein the mechanism to modify the locomotion of each of said one or a plurality of crutches over the surface is selected from the group of mechanisms consisting of a mechanical mechanism having a pin and a ratchet, a mechanical brake mechanism, an electromagnetic brake mechanism, a pneumatic brake mechanism, and an electrical brake mechanism. ### Claim 6 (depends on 1) The system of claim 1, wherein a crutch of said one or a plurality of crutches further comprises a manipulatable handle. ### Claim 7 (depends on 6) The system of claim 6, wherein the manipulatable handle is configured to facilitate the modification of the locomotion of said one or a plurality of crutches over the surface. ### Claim 8 (depends on 1) The system of claim 1, wherein the mechanism to modify the locomotion of that crutch over the surface comprises a limiter to limit an angular range of that crutch. ### Claim 9 (depends on 1) The system of claim 1, wherein the gait device comprises a motorized exoskeleton device. ### Claim 10 (depends on 9) The system of claim 9, wherein the one or a plurality of crutches is coupled to the motorized exoskeleton device. ### Claim 11 (depends on 1) The system of claim 1, wherein a length of a crutch of said one or a plurality of crutches is modifiable in response to a change in an environment. ### Claim 12 (depends on 1) The system of claim 1, comprising a processing unit to control the mechanism to modify the locomotion of that crutch over the surface. ### Claim 13 (depends on 1) The system of claim 1, wherein said one or a plurality of crutches comprises at least two crutches, and wherein said at least two crutches are coupled. ### Claim 14 One or a plurality of crutches for use with a gait device to provide support over a surface to the gait device, each of said one or a plurality of crutches comprising a locomotion facilitator to enhance locomotion of that crutch over the surface and a mechanism to modify the locomotion of that crutch over the surface. ### Claim 15 (depends on 14) The one or a plurality of crutches of claim 14, wherein the mechanism to modify the locomotion of each of said one or a plurality of crutches over the surface is selected from the group of mechanisms consisting of a mechanical mechanism having a pin and a ratchet, a mechanical brake mechanism, an electromagnetic brake mechanism, a pneumatic brake mechanism, and an electrical brake mechanism. ### Claim 16 (depends on 14) The one or a plurality of crutches of claim 14, wherein a length of a crutch of said one or a plurality of crutches is modifiable in response to a change in an environment. ### Claim 17 (depends on 14) The one or a plurality of crutches of claim 14, wherein the mechanism to modify the locomotion of the crutch over the surface comprises a limiter to limit an angular range of the crutch. ### Claim 18 A method comprising: facilitating a gait of a person over a surface using a gait device for; and using one or a plurality of crutches to provide support over the surface to the gait device, each of said one or a plurality of crutches comprising a locomotion facilitator to enhance locomotion of that crutch over the surface and a mechanism to modify the locomotion of that crutch over the surface. ### Claim 19 (depends on 18) The method of claim 18, wherein the locomotion facilitator is configured to change a direction of locomotion of the person using the gait device. ### Claim 20 (depends on 18) The method of claim 18, comprising modifying a length of a crutch of said one or a plurality of crutches in response to a change in an environment.
