A personal mobility device includes a frame, a plurality of wheels attached to the frame and one or more pneumatic motors. Each of the one or more pneumatic motors has a drive shaft in operative connection with at least one of the plurality of wheels. The personal mobility device further includes at least one tank (that is, a storage container) for storage of a pressurized gas in operative connection with the one or more pneumatic motors to supply pressurized gas to the one or more pneumatic motors and a control system in operative connection with the at least one tank and with the one or more pneumatic motors.

A toe dynamometer is configured to accurately and precisely measure toe extensor strength. The toe dynamometer includes a platform configured to accommodate a patient's foot, and a sensor assembly comprising a force sensor and a toe cap connected to the force sensor. The force sensor is configured to measure forces applied to the force sensor by toe flexion on the force sensor and from toe extension away on the force sensor through the toe cap.

Apparatus and method for measuring toe flexion and extension

A wheelchair includes a frame, a seat attached to the frame, a first forward wheel on a first side of the frame and a second forward wheel on a second side of the frame, a first rearward wheel on the first side of the frame and a second rearward wheel on the second side of the frame, a first drive wheel on the first side of the frame positioned intermediate between the first forward wheel and the first rearward wheel and a second drive wheel on the second side of the frame positioned intermediate between the second forward wheel and the second rearward wheel, and actuators to independently control the vertical position of the first forward wheel relative to the frame, the vertical position of the second forward wheel relative to the frame, the vertical position of the first rearward wheel relative to the frame, the vertical position of the second rearward wheel relative to the frame, the vertical position of the first drive wheel relative to the frame and the vertical position of the second drive wheel relative to the frame.

Angle adjustable backrest made of a lightweight, durable, adjustable, backrest for ultralight manual wheelchairs. Light-weight material can include composites for a rigid backrest for promotion of healthier and functional interface. Angle adjustment can be any desired range such as a range from &#x2212;5 degree to 55 degrees (i.e. 85 degrees to 145 degree with respect to horizontal with the seat). No tools are necessary for any of the angle adjustments. The backrest has a horizontal adjustment (fore-aft) that can be any desired range such as 1 inch. The height selection depends on the length of the wheelchair frame tubes. The present invention improves the ease and simplicity of adjusting the backrest by or for the user, as well as enhances the aesthetic appearance and adds features necessary for achieving commercial readiness. The present invention can be retro fit onto a wide range for ultralight wheelchairs.
