The present invention relates to improvements in or relating to tremor stabilisation apparatus and methods, in particular to gyroscopic devices for use in controlling tremors of parts of the body, both physiological and pathological, especially the hands. We describe an apparatus for reducing effects of tremors on the human body. The apparatus comprises a wearable element and at least one gyroscopic device mounted or mountable to the wearable element, the gyroscopic device comprising a gyroscope and a gyroscope housing. The apparatus is characterised in that the at least one gyroscopic device is mounted within the housing by means of a mount which allows the gyroscope to precess with respect to the housing. In one embodiment, the mount comprises a hinge to which the gyroscope is mounted and a hinge plate or hinge mount to which the hinge is mounted for rotation with respect to the gyroscope housing. Preferably the hinge plate or hinge mount comprises a turntable mounted to the gyroscope housing. Preferably, the or each gyroscopic device further comprises a control arrangement to control the precession of the gyroscope.

A sports training apparatus for practicing lacrosse comprising an elongate rigid member extending along a length between first and second ends, first and second stops secured to the elongate rigid member, and a slidable mass on the elongate rigid member, slidable along the elongate rigid member between the first and second stops. A kit for retrofitting a lacrosse stick for practicing lacrosse comprising first and second stops, securable to a lacrosse stick; and a slidable mass, having a passage along an axis there through. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A rotation exercising ball structure includes two shells, two pivot seats, a weight unit, and two handle protecting members. The two shells are combined to construct a hollow ball. Each of the two shells has a space. Each of the two pivot seats is formed on the space and has a through hole. The weight unit includes a mandrel, a rotation member, two bearings, and a weight. The mandrel has two ends each secured in the through hole of one of the two pivot seats. The rotation member has a first end provided with a mounting hole for mounting the two bearings. The weight connects a second end of the rotation member. The rotation member and the weight are rotated on the mandrel. The two handle protecting members are mounted on the two shells.

The gyroscopic exercise device, comprised of one or more rotating mass equipped with accompanying gears, bearings, and optional components, encased in a frame connected to an attachment which contains additional optional equipment including electric motors, magnets, batteries, wiring and electronics, to which one or more handles or grips are connected in a temporary or fixed position, intended to overcome the high degree of difficulty and failure new users experience when using prior art friction-based gyroscopic exercise devices, by providing a novel driving system and rotor that is substantially more efficiency, powerful and durable with means of servicing wear points, enables users to consistently progress, further encouraging regular use, thereby developing greater strength circulation, and coordination in the hands, arms and upper body, which enhances stability and control when users operate handheld equipment.

Training neck muscles in such a way as to improve responsiveness to head acceleration forces, and to help prevent concussion and/or screening subjects who are at high risk of concussion, especially from contact sports or military activities, may be accomplished by a device and/or method of training that incorporates an adjustable centripetal force about a fixed axis on the head. The centripetal force may be adjusted through varying the weight and/or length of a force arm, and neck muscle performance may be measured by a number of revolutions of the force arm completed over a set time period or a time required to complete a pre-determined number of revolutions of the force arm.

Disclosed herein is a gyroscopic exercise apparatus. The present invention is comprised of a rotatable disc, a pair of retractable strings, and attachment means to connect the rotatable disc with the retractable strings. The rotatable disc is comprised of an outer ring structure that has crisscross connecting rods connecting the outer ring structure with inner center disc, and two plastic insert holes to allow the passage of retractable strings from the disc. This process will create tension when twisted and turned due to back and forth movement of the rotatable disc, which causes muscle development and fatigue.

The invention provides an exercise device for a rotator cuff of a shoulder of a user comprising a container housing, wherein the container housing comprises a first container shell, wherein the first container shell comprises a first container shell exterior surface and a first container shell interior surface surrounding a first container shell void, wherein the first container shell interior surface forms a substantially spherical surface; a second container shell, wherein the second container shell comprises a second container shell exterior surface and a second container shell interior surface, wherein the second container shell interior surface surrounds the first container shell exterior surface whereby the first container shell is nested inside the second container shell; and a spherical ball positioned within the first container shell void; wherein when the exercise device is in use, movement and rotation of an arm of a user causes movement and rotation of the container housing and movement and rotation of the ball within the container housing in a direction that follows a circumference of the first container shell interior surface, thereby exercising the rotator cuff of the shoulder of the user.

A foam roller includes a cylindrical main body having a hollow interior extending in a first direction. The foam roller further includes a first portal and a second portal extending into said cylindrical main body in a second direction transverse to said first direction and inline with each other. The foam roller further includes a first arm and a second arm. The first arm is sized to fit within said first portal and the second arm sized to fit within the second portal. The foam roller can be rolled by way of the arms while a torso is held against the roller. The arms are fixedly or removably connected to the roller portion thereof and prevent the roller from rolling fully around which being rollable by way of pulling the arms. The foam roller may also include end caps on the roller to attach the arms thereto.

A rotation exercising ball structure includes two shells, two pivot seats, a weight unit, and two handle protecting members. The two shells are combined to construct a hollow ball. Each of the two shells has a space. Each of the two pivot seats is formed on the space and has a through hole. The weight unit includes a mandrel, a rotation member, two bearings, and a weight. The mandrel has two ends each secured in the through hole of one of the two pivot seats. The rotation member has a first end provided with a mounting hole for mounting the two bearings. The weight connects a second end of the rotation member. The rotation member and the weight are rotated on the mandrel. The two handle protecting members are mounted on the two shells.
