In some embodiments, a mobility assist device can include a wrist stabilizer and one or more exercising elements for enabling a user to perform torsion, rotation, grip, and/or other exercises. ## Claims ### Claim 1 An apparatus, comprising: a shaft assembly including first and second shafts that are adjustable relative to one another; a handle coupled to one end of the shaft assembly; a wrist stabilizer including a wrist support and a forearm support, the wrist stabilizer coupled to the handle such that the wrist stabilizer can provide support in flexion or extension to a user when the user rests a forearm of the user on the forearm support and a wrist of the user on the wrist support while gripping the handle with a hand of the user; and a base coupled to the opposite end of the shaft assembly. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the wrist stabilizer includes a frame, and the forearm support includes a hinge coupled to the frame. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the forearm support includes a flexible portion configured to enable one or more of translation and rotation of the forearm support relative to a longitudinal axis of the wrist stabilizer. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the forearm support is configured to be on an anterior side of a forearm of the user and the wrist support is configured to be on a posterior side of the wrist when in extension, and wherein the forearm support is configured to be on a posterior side of the forearm of the user and the wrist support is configured to be on an anterior side of the wrist when in flexion. ### Claim 5 (depends on 1) The apparatus of claim 1, further comprising: a grip exerciser coupled to the handle via one or more coupling elements, the one or more coupling elements configured to provide resistance to a displacement of the grip exerciser, the grip exerciser configured to displace relative to the handle to allow a user to perform a grip exercise. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the grip exerciser is configured to release from a recess of the handle or the first shaft. ### Claim 7 (depends on 5) The apparatus of claim 5, wherein the grip exerciser includes a spring. ### Claim 8 (depends on 1) The apparatus of claim 1, further comprising: a torsion exerciser coupled to at least one shaft of the shaft assembly, the torsion exerciser having opposite ends configured to be rotated in opposite directions about a longitudinal axis of the shaft assembly, the torsion exerciser configured to provide resistance in torsion when the opposite ends of the torsion exerciser are rotated. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the torsion exerciser includes one or more elastic elements. ### Claim 10 (depends on 1) The apparatus of claim 1, further comprising: a tension exerciser having a first end coupled to the first shaft of the shaft assembly and a second end coupled to the second shaft of the shaft assembly that is adjacent to the first shaft, the first and second shafts movable relative to one another, the tension exerciser configured to provide resistance in tension when the first and second shafts are moved away from one another. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the tension exerciser includes one or more elastic elements. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the first end is coupled to an inner surface of the first shaft and the second end is coupled to an inner surface of the second shaft. ### Claim 13 (depends on 1) The apparatus of claim 1, further comprising: one or more grips coupled to one or more shafts of the shaft assembly, the grips configured to be gripped by a user while rotating the shaft assembly in a clockwise or counterclockwise manner. ### Claim 14 (depends on 1) The apparatus of claim 1, wherein the base includes a footrest configured to transition from a closed configuration extending generally parallel to a longitudinal axis of the shaft assembly and an open configuration extending generally laterally away from the longitudinal axis of the shaft assembly. ### Claim 15 (depends on 1) The apparatus of claim 1, wherein the footrest includes one or more legs at an end of the base. ### Claim 16 A method, comprising: inserting a hand of a user through a forearm support of a wrist stabilizer to apply pressure to an anterior side of a forearm or a posterior side of the forearm; inserting the hand through a wrist support of the wrist stabilizer to apply pressure to a posterior side of a wrist or an anterior side of the wrist; grasping a handle coupled to the wrist stabilizer to apply lateral pressure to the handle; and applying a load to mobility assist device coupled to the handle. ### Claim 17 (depends on 16) The method of claim 16, further comprising squeezing a grip exerciser coupled to the handle using the hand. ### Claim 18 (depends on 16) The method of claim 16, further comprising rotating opposite ends of a torsion exerciser of the mobility assist device in opposite directions. ### Claim 19 (depends on 16) The method of claim 16, further comprising pulling opposing ends of a tension exerciser of the mobility assist device away from each other. ### Claim 20 A kit, comprising: a shaft assembly including first and second shafts that are adjustable relative to one another; a handle coupleable to one end of the shaft assembly; a wrist stabilizer including a wrist support and a forearm support, the wrist stabilizer coupleable to the handle such that the wrist stabilizer can provide support in flexion or extension to a user when the user rests a forearm of the user on the forearm support and a wrist of the user on the wrist support while gripping the handle with a hand of the user; and a base coupleable to the opposite end of the shaft assembly. ### Claim 21 (depends on 20) The kit of claim 20, further comprising a set of exercisers coupleable to the shaft assembly. ### Claim 22 (depends on 20) The kit of claim 20, wherein the base comprises a set of different bases. ### Claim 23 (depends on 20) The kit of claim 20, further comprising: a grip exerciser coupleable to the handle via one or more coupling elements, the one or more coupling elements configured to provide resistance to a displacement of the grip exerciser, the grip exerciser configured to displace relative to the handle to allow a user to perform a grip exercise. ### Claim 24 (depends on 20) The kit of claim 20, further comprising: a torsion exerciser coupleable to at least one shaft of the shaft assembly, the torsion exerciser having opposite ends configured to be rotated in opposite direction about a longitudinal axis of the shaft assembly, the torsion exerciser configured to provide resistance in torsion when the opposite ends of the torsion exerciser are rotated. ### Claim 25 (depends on 20) The kit of claim 20, further comprising: a tension exerciser having a first end coupleable to the first shaft of the shaft assembly and a second end coupled to the second shaft of the shaft assembly that is adjacent to the first shaft, the first and second shafts movable relative to one another, the tension exerciser configured to provide resistance in tension when the first and second shafts are moved away from one another. ### Claim 26 (depends on 20) The kit of claim 20, further comprising: one or more grips coupleable to one or more shafts of the shaft assembly, the grips configured to be gripped by a user while rotating the shaft assembly in a clockwise or counterclockwise manner. ### Claim 27 (depends on 20) The kit of claim 20, wherein the base includes a footrest configured to transition from a closed configuration extending generally parallel to a longitudinal axis of the shaft assembly and an open configuration extending generally laterally away from the longitudinal axis of the shaft assembly.
