A human interface device is configured to be coupled to a trunk of a person and comprises a frame, a fabric coupled to said frame configurable to be under tensile forces, and a belt configured to be coupled to two side edges of said frame wherein when said belt is worn by said person, an area of said fabric will be pushed against the person's lower back conforming to the shape of the lower back of said person. In operation when said human interface device is worn by said person, the weight of any load coupled to or supported by said frame will be partially supported by the friction force between the area of said fabric which is pushed against the person's lower back, and the person's lower back allowing said person to carry said load.

An assist device control system is provided. The control system includes an improvement effect data storing unit that stores improvement effect data, which represents a correlation between an improvement effect and an assist force, for each target item for every reference unit period for a plurality of types of target items, a data recognizing unit that recognizes the improvement effect data for each of a plurality of target items, and a schedule determining unit that compares the recognized improvement effect data, determines a target item to be prioritized for every reference unit period, and determines the assist force to be generated for every reference unit period on the basis of the improvement effect data of the target item to be prioritized.

A lifting belt includes a lifter configured to generate a tractive force in a longitudinal direction of a spinal column by expansion, a left connector and a right connector respectively disposed on a left side and a right side of the lifter, and a central connector attachable to or detachable from the left connector and the right connector.

An apparatus for fixing bad posture includes a support rod, multiple length-adjustable straps, and multiple strap-attachment points. The apparatus for fixing bad posture prevents the user from slouching by affixing the support rod to the user's back with the straps. The support rod is a rigid member that is placed against a user's back. The support rod has a rod body, a mounting face, and a bracing face. The rod body is the structural component of the support rod. The bracing face and mounting face are positioned on opposite lateral surfaces of the rod body. Thus positioned, the bracing face is pressed against the user's back when correcting posture. The strap-attachment points are connection mechanisms for the length-adjustable straps that are distributed along the length of the support rod. As such, each of the length-adjustable straps is attached to the support rod by a corresponding strap-attachment point.

A trunk orthosis including a bandage that is designed to be put on a patient's trunk, and a supporting device which is connected to the bandage and which the supporting device is designed as a frame with frame sections that are hingedly or elastically secured to one another, are spring-biased, and are pre-stressed by the bandage when worn on the patient's trunk.

A human motion assistance device has upper back straps and is configured to attach to a user. A leg strap arrangement with lower back straps is configured to attach to the user. A differential assembly is connected between the upper back straps and lower back straps to reduce resistance of the upper torso harness and leg strap arrangement during gait. When crouching or lifting, the differential assembly transfers force to stretch and retract the upper torso harness and leg strap arrangement, which provides human motion assistance. The differential assembly can be implements as an x-bar, lever arm, pulley, gears, or tube. The leg strap arrangement has a knee pad adapted to cover a knee of the user. The knee pad opens along a segment. The upper torso harness has a shoulder strap and buckle. The leg strap arrangement is an elastic material.

A scoliosis activity suit includes a body-wrapping portion and a correction portion. The correction portion has a front segment, a rear segment, a shoulder-pulling segment, a chest-pressing segment, a pelvis-lifting segment, and a upper trapezius pressing segment. The shoulder-pulling segment, the chest-pressing segment, the pelvis-lifting segment, and the upper trapezius pressing segment are formed on a front side of the body-wrapping portion and extend to the rear segment of the correction portion. To users with scoliosis, the correction portion generates a 3D compression force on different portions of the spine of the user, such that a backward pulling force against a protracted portion of the shoulder, an uplifting force against an inclined portion of the pelvis, and a pulling force against portions with spinal sidebend can be provided. Besides, being lightweight and easy for users to wear, the suit fulfills practice of daily life adjustment and correction for scoliosis.

An improved Scoliosis Boston Brace having self-tightening mechanism is disclosed, which tightens the brace around the patient's body with a motorized mechanism. The self-tightening mechanism makes it easier for the patient to tighten the brace around their body, and also eases the task of putting on/off, the brace. The components of the present invention includes a Boston brace, a worm drive, worm drive rack, a hexagonal peg, nylon strap, rivet, two parts epoxy glue, buttons and motor screwdriver. The worm drive and the worm drive rack are connected to the nylon strap, which is attached through rivet to the Boston Brace. The hexagonal peg helps in manipulating the worm drive, which determines the tightness of the brace; and the button attached to worm drive rack, helps to unclasp the mechanism when taking off the brace.

Disclosed are systems and methods correction of spinal deformity that overcome current limitations by utilizing a dynamic, multi-segment torso orthosis that allows motion during wear. The disclosed embodiments utilize a series of elastically coupled segments that conform to the circumference of the torso of a patient. Adjustable elastic coupling mechanisms are utilized to create and alter forces and moments that are applied to the torso through the segments. These elastic coupling mechanisms also allows each circumferential segment to move relative to the other segments giving the brace dynamic capability.
