An apparatus that imparts a propelling force upon a body when stepping forward during walking motion is comprised of and assembled concentrically together with a stick, pin, elastic tube, coupler, and hand held grip. The user rotates the apparatus in a forward circular motion towards the same direction of travel about a fixed location at the stick bottom on the ground surface. An impulse occurs from the apparatus upon the ground surface that is caused by the arm and upper body muscular contractions working against the elongation of the elastic tube. Then the coupler that is attached to the recoiling elastic tube attains a momentum that equals the combined masses of the coupler and grasped hand multiplied by the resultant of the tangential and radial velocity vectors. Both resultant impulse and momentum vectors are combined with the user's forward momentum because the user holds onto the grip of the device.

Embodiments of a smart mobility aid device may have sensors to collect, monitor, analyze and represent data including but not limited to activity tracking, biometrics and safety and emergency features. The activity tracking include number of steps, miles, and activity speed, user pressure on a device, activity types and analysis. The user biometric data includes but is not limited to blood work, blood pressure, blood sugar, heart rate, oxygen level/rate, ECG, EMG, muscle strain, humidity, UV, body temperature. Additional features include an emergency button, fall detection, warnings, and user pattern analysis changes. The mobility aid device is connected to other smart electronic device and/or the Internet using but not limited to Bluetooth, Wi-Fi, and or/and SIM card. The device gives the user or/and caregiver live feedback about user health metrics and status using a data representation method.

A variety of ski and hiking poles are described. In one aspect, magnets are provided on the pole handles and baskets to facilitate magnetic coupling a pair of poles together in a state suitable for carrying. In some embodiments, a pair of magnets are provided on each side of the handle. In some embodiments, a basket alignment piece is attached to the pole shaft. The alignment piece helps facilitate attachment of the basket to the pole shaft in an orientation that aligns the basket magnets relative to the handle magnets. In another aspect novel wrist straps are described.

For ski poles, walking poles and similar, a length-adjusting arrangement including an inner element 2 and an outer tube 1, there being a locking device 3 on this same first end 11 of the outer tube 1, with which locking device 3 the inner element 2 and the outer tube 1 can be releasably locked in various axial positions relative to each other, there also being a regulating device 4 on the other end 12 of the outer tube 1, with which regulating device 4 the locking device 3 can be manoeuvred, the outer mantle surface of the inner element 1 2 including two or more cut-outs 21 arranged at a distance from each other in the axial direction of the inner 419 element 2, the locking device 3 including a latching element 32 that is axially fixed relative to the outer tube 1 but, relative to this same outer tube 1, is displaceable between a first position where parts of said latching element 32 are inserted in one of said cut-outs 21 and a second position where said latching element 32 is disengaged from said cut-outs 21 and where the latching element 32 being moved, under the influence of a spring member 43, in a direction towards said first position, in which position the inner element 2 and the outer tube 1 are locked in the axial direction relative to each other and where the latching element 32 is moved, under the influence of the regulating device 4, in a direction towards said second position via an axially displaceable control 6, this control 6 being in the space between the outer mantle surface of the inner element 2 and the inner mantle surface of the outer tube 1, said control 6 extending axially from said locking device 3 to said regulating device 4 and where, in said second position, the inner element 2 and the outer tube 1 can be displaced in the axial direction relative to each other.

The invention is a versatile walking stick that can be used in a wide variety of environments, including (but not limited to) swamps and wetlands. The walking stick includes a first end, an opposed second end, and a body that spans the distance between the two ends. The second end of the walking stick includes two or more feet that extend outwards from a central support. Advantageously, the spring actuated feet are configured to fold under tension when pulled in an upward direction (e.g., out of mud or any other tacky material). Once freed from the mud, the feet spring upwards and provide a wide surface area that allows a user to easily move through the terrain.

A smart walking cane may include a smart cane, a smart device, and a smart software. The smart cane has a cane body, and a cane handle is formed on the top of the cane body to be held by the user. The cane body comprises a nine-axis inertial sensor, a pressure sensor, and a photoelectric sensor. The nine-axis inertial sensor has a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer, and the three-axis accelerometer is used to detect the gravitational acceleration of the smart cane along the X, Y, and Z axes, allowing for the detection of movement speed, step count, and whether the user's hand has tremors while using the smart cane.

The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a roll-walk device. The device is a pair of walking sticks or poles that enables users to exercise their upper body by mimicking (i.e., the arm and upper body movements of) a walking, hiking, and/or skiing motion while sitting down. The base of each walking stick or pole features an interchangeable mechanism that enables users to swap out the standard base with a set of wheels. Thus, once the device is equipped with the wheels, the user can sit comfortably while mimicking (i.e., the arm and upper body movements of) a walking, hiking, and/or skiing motion to exercise their upper body.

A device with a quickly adjustable length comprises an outer tube component and an inner tube component, wherein the inner tube component is slidably arranged in the outer tube component, the inner tube component comprises a connecting end, the connecting end is provided with an adjusting device, the inner tube component is provided with a transmission component, the adjusting device comprises a fixing component and an expansion component, the fixing component has a first end and a second end, the fixing component has an axial width gradually increasing from the first end to the second end, and the transmission component passes through the fixing component. The transmission component can drive the expansion component away from or close to the second end, so that the expansion component has a radially contracted and expanded state, thereby keeping the inner tube component and the outer tube component relatively sliding or locked.

Disclosed herein is an orthopedic device and methods to aid in reducing weight or pressure on a portion of a subject's knee while maintaining stability and normal gait patterns following injury or surgery. Certain embodiments include a main shaft for use in an orthopedic device, wherein the main shaft includes a curved portion. In embodiments, the curved portion cures outwardly in the walking direction. The curvature can comprise a curvature that is consistent with the maximum knee flexion angle that is observed during the loading phase of the normal gait cycle. In embodiments, the device further comprises a handle portion and a foot, wherein the main shaft is disposed between the handle portion and the foot. Additional aspects include a method of promoting the healing or recovery in a subject following injury or surgery of the knee using any one or more of the orthopedic devices disclosed herein.
