21339 results about "Physical medicine and rehabilitation" patented technology

Physical medicine and rehabilitation, also known as physiatry and physiatrics (but this can also refer to physiotherapy), is a branch of medicine that aims to enhance and restore functional ability and quality of life to those with physical impairments or disabilities. A physician having completed training in this field may be referred to as a physiatrist. Physiatrists specialize in restoring optimal function to people with injuries to the muscles, bones, ligaments, or nervous system.

Monitoring activity of a user in locomotion on foot

In one embodiment, a method includes steps of: (a) identifying an average foot contact time of a user during a first outing; (b) identifying an average pace of the user during the first outing; (c) defining a relationship between foot contact times of the user and corresponding paces of the user, wherein the relationship is based upon the average foot contact time and the average pace identified during the first outing, and wherein no other average foot contact times and no other average paces identified during any different outings by the user are used to define the relationship; and (d) calibrating at least one device that monitors activity of the user in locomotion on foot based upon the defined relationship between foot contact times of the user and corresponding paces of the user. In another embodiment, a method includes steps of: (a) determining a single user-specific calibration constant that defines a relationship between foot contact times of a user and corresponding paces of the user, wherein no other user-specific calibration constants are used to define the relationship; and (b) calibrating at least one device that monitors activity of the user in locomotion on foot based upon the relationship between foot contact times of the user and corresponding paces of the user that is defined by the single user-specific calibration constant.

Device and method for correcting and stabilizing a deviating curvature of a spinal column

A device for correcting and stabilizing a curvature of a spinal column by anterior fusion including at least two brace holders (1-5), each adapted to be arranged against an associated vertebral body (7-11) in the spinal column. The device also includes a securing means (6, 6') for securing the respective brace holders (1-5) on said vertebral body (7-11), and at least one elongate brace (12), which is adapted to extend through and between said brace holders (1-5) along the extent of the spinal column and be locked thereto. The brace (12) is plate-shaped, and the brace holder (1-5) is designed to support the brace (12) in such a manner that a first flat side of the brace (12) faces the abutment surface of the brace holder (1-5) on said vertebral body (7-11), whereby the brace (12) is deformable in only one geometric plane during mounting in the brace holder (1-5) and during correction. In a method for contacting and stabilizing the curvature, the brace (12) is arranged to extend through the brace holders (1-5), such that the brace (12) is deformed to substantially follow the curvature. The brace is locked in at least one first brace holder (1), whereupon the spinal column, vertebra by vertebra, is corrected while the brace (12) is gradually clamped and locked in the brace holders (1-5).

Adaptive method and apparatus for forecasting and controlling neurological disturbances under a multi-level control

InactiveUS7146218B2Avoid injuryPrevent and avoid seizureElectroencephalographyElectrotherapyFeature setPupil
A method and apparatus for forecasting and controlling neurological abnormalities in humans such as seizures or other brain disturbances. The system is based on a multi-level control strategy. Using as inputs one or more types of physiological measures such as brain electrical, chemical or magnetic activity, heart rate, pupil dilation, eye movement, temperature, chemical concentration of certain substances, a feature set is selected off-line from a pre-programmed feature library contained in a high level controller within a supervisory control architecture. This high level controller stores the feature library within a notebook or external PC. The supervisory control also contains a knowledge base that is continuously updated at discrete steps with the feedback information coming from an implantable device where the selected feature set (feature vector) is implemented. This high level controller also establishes the initial system settings (off-line) and subsequent settings (on-line) or tunings through an outer control loop by an intelligent procedure that incorporates knowledge as it arises. The subsequent adaptive settings for the system are determined in conjunction with a low-level controller that resides within the implantable device. The device has the capabilities of forecasting brain disturbances, controlling the disturbances, or both. Forecasting is achieved by indicating the probability of an oncoming seizure within one or more time frames, which is accomplished through an inner-loop control law and a feedback necessary to prevent or control the neurological event by either electrical, chemical, cognitive, sensory, and/or magnetic stimulation.

Passive force feedback for computer interface devices

A method and apparatus for interfacing the motion of an object with a digital processing system includes a sensor which has a sensing resolution and detects movement of the object along a degree of freedom. An amount of play less than the sesning resolution exists between the sensor and the object. A passive actuator is coupled to the mechanism to transmit a resistive force to the object along the degree of freedom. A play mechanism is coupled to the actuator to provide a desired amount of play between the actuator and the object along the degree of freedom. The desired amount of play is greater than the sensing resolution of the sensor so that the sensor can detect the desired play when the user moves the object, even when the actuator has locked the object into place. Such desired play can be torsion flex (compliance) or rotary backlash. The actuator and the sensor provide an electromechanical interface between the object and the digital processing system. A gimbal mechanism or slotted yoke mechanism can be coupled between the actuator and the object. The interface is well suited for simulations of medical procedures and simulations in which an object such as a stylus or a joystick is moved and manipulated by the user.
