The operator adjustable workstation facilitates adjustments ranging from a seated work level to a standing work level with an infinite number of health posture arrangements and work surface levels in between. Two trigger controlled height and angle adjustment body support actuators and a foot controlled lower leg and lower leg support pivot actuator, provide the operator with independent control to quickly lock into place and/or release each health posture and work surface at any level within the adjustment range. The workstation includes a base structure, a body support area, a work surface area, and lift arm. The work surface area incorporates two substantially planar work surfaces. The body support area incorporates seat, back, lower leg and lower leg support components. The body support and work areas incorporate two separate lift arms. The lift arms have first ends and second ends.

An operator adjustable workstation, ranging from a seated work level to a standing work level with an infinite number of health posture arrangements and work surface levels in between. Two trigger controlled height and angle adjustment body support actuators and a foot controlled lower leg and lower leg support pivot actuator, provide the operator with independent control to quickly lock into place and/or release each health posture and work surface at any level within the adjustment range. The workstation includes a base structure, a body support area, a work surface area, and lift arm. The work surface area incorporates two substantially planar work surfaces. The body support area incorporates seat, back, lower leg and lower leg support components. The body support and work areas incorporate two separate lift arms. The lift arms have first ends and second ends. The first ends are pivotally secured to the base structure while the second ends are pivotally secured to their respective body support and work area components. These first ends and second ends pivot through a range of motion to raise and lower the work and body support areas from a seated to a standing work level.

Apparatus and associated methods may relate a to natural gait upper body ergometer and gait therapy (UBEGT) device having a support frame within which is suspended rotationally coordinated left and right natural gait modules (NGMs). A position of each NGM may be defined by corresponding left and right pivot arms which are rotatably coupled to a left and right side of the support frame, respectively, and wherein each gait training module is provided with a corresponding foot support and knee support. The UBEGT may be provided with an upper body ergometer (UBE) rotatably coupled to a front of the support frame and configured to rotate a shaft rotatably connected to the left and right pivot arms when a hand crank is rotated.

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.

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.

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.
