A corrugated tube includes a hollow tube formed of several crests and several troughs connected alternately. The middle of an end face of a tail end of the corrugated tube is provided with a boss; and both a first section of a head end and a last section of a tail end of the corrugated tube are crests, with the width of both the crest of the first section of the head end and the crest of the last section of the tail end being greater than the thickness of the corrugated tube, preventing the tail end and the head end of the corrugated tube from collapsing inwards when the air pressure in the corrugated tube decreases.

A method for exercising a joint and a limb including the following: preventing movement of an exercise device actuation member in a first direction unless force exerted by the limb against the actuation member is equal to or greater than a predetermined first target force; permitting movement of the actuation member in the first direction at a first predetermined speed when force exerted by the limb against the actuation member is equal to or greater than a predetermined first target force; preventing movement of the actuation member in a second direction unless force exerted by the limb against the actuation member is equal to or greater than a predetermined second target force; and permitting movement of the actuation member in the second direction at a second predetermined speed when force exerted by the limb against the actuation member is equal to or greater than a predetermined second target force.

Described is an exercise tool. More particularly, it is a therapy and exercise tool specifically devised as a foot-therapy and toe-aligning device to align, separate, and stretch toes. The foot-therapy and toe-aligning device comprises a frame with a plurality of posts connected with the frame. The device is formed of an elastic material such that a user may place at least one of the plurality of posts between a user's toes and pull the post to stretch and elongate the post between the toes. Upon release, the elastic material of the post causes the post to attempt to return to its original shape, thereby causing it to expand out and conform its shape to fit snugly against the user's toes. Additionally, the elastic material allows the toe posts to be positioned and maintained at numerous locations between the user's toes for customizable positioning between the toes.

A method for exercising a joint and a limb of a patient. The method includes supporting the limb at an angle with an actuation arm of an exercise device. The actuation arm is rotatable about a rotation axis and includes a first portion and a second portion. The second portion is movable in a direction perpendicular to the rotation axis. The method further includes restricting movement of the second portion of the actuation arm and a foot plate at a distal end of the second portion in the direction perpendicular to the rotation axis unless force exerted on the foot plate by the patient exceeds a predetermined force as measured by a foot plate load cell.

An apparatus applies traction to a big toe of a patient's foot at a desired adduction angle and a desired dorsiflexion angle, for use in treating a bunion. The apparatus includes: a shoe portion (e.g., a sole, and strap(s)); a toe attachment apparatus (e.g., a Chinese finger trap) having a cable extending therefrom; and an apparatus (e.g., a ratchet, an actuator, and the like) configured to apply tension to the cable with respect to the sole. A support bracket is configured to pivot with respect to the shoe portion to adjust the adduction angle of the cable with respect to an axial direction of the sole, and is further configured to extend upwardly to at an elevated position with respect to the sole. An adjustment member is mounted to slide relative to the support bracket, to adjust the dorsiflexion angle provided by the cable independent of the adduction angle.

A foot stretching/checkup device includes: a motor unit; a footrest unit including a lower footrest configured to be rotated about a first rotation axis, an upper footrest configured to be rotated about a second rotation axis and a connecting member connecting the upper footrest and the lower footrest; and a coupling unit including an arm portion rotated by the motor unit and a rotary coupler coupled to the upper footrest. The upper footrest is configured to be rotated by a predetermined angle about the second rotation axis by the rotation of the arm portion. The lower footrest is configured not to be rotated about the first rotation axis by rotation of the arm portion until the upper footrest is rotated by the predetermined angle.

An orthosis for stretching the tissue around a foot and a toe of a wearer includes a first member affixable to the foot and a second member operatively connected to the first member and affixable to the toe. A gear is connected to the second member and rotates relative to the first member to impart movement of the second member relative to the first member. A drive assembly is operatively coupled to the gear and drives rotation of the gear, thereby driving movement of the second member relative to the first member such that the toe moves relative to the foot.

A motion assistance apparatus including a proximal support configured to support a proximal part of a user, a first drive link and a second drive link configured to perform translational motions with respect to the proximal support at different velocities, a support link with both ends rotatably connected to the first drive link and the second drive link, respectively, the support link having a variable length, and a distal support connected to the support link, the distal support configured to support a distal part of the user is provided.
