Patent number: 9050230Abstract: Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a belt support frame, at least two rollers mounted on the belt support frame and a belt mounted around the at least two rollers. The belt support frame is adapted for mounting on the frame of the wheelchair such that as the wheelchair descends from the upper surface to the lower surface, the belt engages an edge of the upper surface and rolls around the at least two rollers slowing a descent of the wheelchair from the upper surface to the lower surface.Type: GrantFiled: March 20, 2012Date of Patent: June 9, 2015Assignees: Montefiore Medical Center, The University of HartfordInventors: Avital Fast, Devdas Shetty, Moshe Raz, Giora Rothman

Patent number: 8167317Abstract: Attachments for a manual wheelchair are provided for navigating a wheelchair over obstacles and uneven terrain, such as a typical curb on a street. The attachments provide for regulating the movement of the wheelchair as the wheelchair descends the curb and to prevent the wheelchair from flipping over during such movement. The attachments include a front caster wheel slider assembly on each side of the wheelchair, a follower wheel assembly and a track belt damping bar. The front caster wheel slider assembly includes a piston that will quickly push the front caster wheels down after they roll over the top edge of the curb. The follower wheel assembly acts as a sensor that will release the piston in the assembly after the front caster wheels roll over the top edge of the curb. As the back wheels of the wheelchair roll over and down the curb, the track belt damping bar slows the descent of the wheelchair.Type: GrantFiled: June 21, 2010Date of Patent: May 1, 2012Assignees: Montefiore Medical Center, The University of HartfordInventors: Avital Fast, Devdas Shetty, Moshe Raz, Giora Rothman

Patent number: 7462138Abstract: An ambulatory suspension system for gait rehabilitation has a parallel pair of rails bordering the sides of a training area and a bridge extending between and movable along the rails. A trolley is movable along the bridge and includes a motor driven hoist with a cable extending thereabout and depending from the trolley. The hoist is operable to vary the length of the cable depending from the trolley, and a harness is suspended by the cable. Motors move the bridge along the rails and the trolley along the bridge as the sensors sense the direction of movement of the patient in X and Y directions. The falling motion of a patient supported in the harness is sensed and will immediately disable the system. A computer control receives signals from the sensors and operates the motors so that the patient is held in an upright position.Type: GrantFiled: July 1, 2005Date of Patent: December 9, 2008Assignees: The University of Hartford, Montefiore Medical CenterInventors: Devdas Shetty, Avital Fast, Claudio Campana

Patent number: 5511571Abstract: A method and apparatus for gait measurement in which a walking aid such as a walker, cane, or crutch is instrumented with load sensors to measure the loads in the aid as it is being used. The measured loads are used to analyze the user's gait to insure proper selection and sizing of a walking aid, stability of the user, and proper limb loading. In a preferred embodiment, strain gauges are mounted on the legs of a walker and connected through a signal processing interface to a computer for data analysis and display. The gauges are mounted, calibrated, and connected to the signal processing interface so as to permit measurement of the axial, bending, and torsional forces in each leg of the walker as it is being used. This data is then used for qualitative and quantitative assessment of the user's gait.Type: GrantFiled: November 5, 1993Date of Patent: April 30, 1996Inventors: Ronald S. Adrezin, Marc A.
