Patent number: 10881572Abstract: Apparatus and associated methods relate to a natural gait therapy device having an adjustable gait timing linkage assembly configured to operate an adjustable knee support assembly and an adjustable height foot assembly to simulate a normal walking pattern for a user based on characteristics of the user. In an illustrative example, the adjustable gait timing linkage assembly includes a chain sprocket configured to adjust a degree of heel lift and a length to the point of the heel lift during a normal walking simulation. In some embodiments, a gait stride adjustment assembly may adjust a stride length to accommodate different sized users. The gait stride adjustment assembly may advantageously contribute to the natural walking pattern simulation.Type: GrantFiled: April 11, 2019Date of Patent: January 5, 2021Assignee: ALT Innovations LLCInventors: Alan Tholkes, DuWayne Dandurand

Patent number: 10758774Abstract: Apparatus and associated methods relate to a walking therapy station having multiple right linkages and multiple left linkages, where at least one of the right or left linkages is operably coupled to an actuator to transition the station from a standing mode to a walking mode. In an illustrative example, the station may have five right linkages and five left linkages, with a set of knee pads and foot pads. The station may include an actuator operably coupled to transition the station between walking and standing modes, for example. Various embodiments of the station may enable a user who is disabled or paralyzed to transition from sitting position, to a standing position, and then to a walking position, and provide the user with a very accurate gait and walking motion without putting excessive shear and pressure at the contact points between the station and the user.Type: GrantFiled: October 5, 2018Date of Patent: September 1, 2020Assignee: ALT INNOVATIONS LLCInventors: Alan Tholkes, DuWayne Dandurand, Nathaniel Hallée

Patent number: 10315067Abstract: Apparatus and associated methods may relate to a natural-gait therapy device for enabling a user with a Spinal Cord Injury (SCI) to independently transition between a locked standing position and a user controlled coordinated natural-gait movement, the method including an unlocking of a left and a right foot movement members, rotating one of the unlocked left and right movement members to a half-period gait position that is 180 degrees out of phase with the un-rotated one of the left and right movement members, coupling the left and right movement members in the 180 degree phase differential orientation, and rotating both left and right leg movement members in a natural-gait motion. In some embodiments, the left and right movement members may be uncoupled to permit a gravity assisted return to a standing position. The transition between the standing and the natural-gait motion may facilitate a user to stand before or sit after performing natural-gait therapy.Type: GrantFiled: November 22, 2016Date of Patent: June 11, 2019Assignee: ALT Innovations LLCInventors: Alan Tholkes, DuWayne Dandurand

Patent number: 9616282Abstract: Apparatus and associated methods relate to a knee-position control system having a knee engagement pad, a lower-leg control member and an upper-leg control member, the knee engagement pad configured to naturally position a user's knee in response to movement of a foot-rest of a natural-gait therapy system. In an illustrative embodiment, the upper-leg control member may pivot about a point substantially axially coincident with a user's hip. In some embodiments, the upper-leg control member may be pivotally coupled to the lower-leg control member at a pivot point substantially axially coincident with a user's knee. The lower-leg control member may be pivotably coupled to the foot rest at a pivot point substantially axially coincident with a user's ankle. The knee-position control system may advantageously position a user's knee in a natural position relative to both the user's ankle and the user's hip, in response to movement of the user's foot.Type: GrantFiled: October 31, 2014Date of Patent: April 11, 2017Assignee: ALT Innovations LLCInventors: Alan Tholkes, DuWayne Dandurand
