To provide controlled amounts of resistance to movement in exercise equipment or in orthotic devices, a control module has cooperating resistance elements. The force between the elements is varied in accordance with the position of the elements with respect to each other. For example the control module can connect two splints of a knee brace so that the resistance to flexion and extension are programmed in accordance with the position of the leg and thigh with respect to each other.

Exercise apparatus and technique

A hand-held controller is used to control an apparatus that supports a person. The hand-held controller includes a display that displays graphical images pertaining to functions of the apparatus. An illustrative apparatus comprises a frame and a mattress supported by the frame.

An apparatus and method is presented for promoting movements of a subject in synergic timed correlation with physiological activity. The apparatus includes a synergic programs module that directs the movements in a temporally varying fashion. The synergic programs module causes generation of at least one signal, stimulus, or force, where the movements are performed in response to the at least one signal, stimulus, or force, where each of the at least one signal, stimulus, or force is determined so as to reduce meaning and/or emotional content to the subject, where each signal and stimulus is from a pool that comprises signals and stimuli that are sensorially understandable or recognizable by the subject, and where timing of the movements is based on at least a primary correlation factor and a secondary correlation factor. The primary correlation factor is determined so that the movements are synchronized with referential points of an intrinsically variable cyclical physiological activity. The secondary correlation factor is determined based on (a) fluctuations based on results of a first function; and (b) fluctuations based on a quantity of cycles of the physiological activity elapsing between any two of the movements or any two groupings of the movements, where the quantity of cycles is based on results of a second function.

A wireless control system for use with a patient-support apparatus includes a first receiver located on the patient-support apparatus and a wireless hand-held controller configured to wirelessly communicate with the first receiver to control functions of the patient-support apparatus and/or functions of hospital room equipment. The wireless control system may also include a second receiver located apart from the patient-support apparatus. The wireless hand-held controller may be configured to wirelessly communicate with the second receiver to control functions of the hospital room equipment. Additionally, the wireless control system may include a docking station configured to receive and charge the wireless hand-held controller.

Wireless control system for a patient-support apparatus

A patient support apparatus generally includes a base frame and a support deck supported on the base frame, the support deck comprising a seat portion. A segmented patient support surface is slidably coupled to the support deck. A lift system is coupled to the support deck and the segmented patient support surface. The lift system raises, lowers and tilts the support deck with respect to the base frame, and pivots a torso support segment of the support surface with respect to a leg support segment of the support surface. A foot plate assembly is removably positioned proximate a free end of the support deck, the foot plate assembly receiving a patient's feet when a patient is positioned on the segmented patient support surface thereby enabling the patient to slide the segmented patient support surface relative to the support deck.

Safety features for a continuous motion therapy system of the type including a carriage for supporting a patient's limb, a drive unit for driving the carriage through a range of reciprocal angular movement, first and second channel neuromuscular stimulators for applying electrical stimulation to muscles of a patient's limb, and a controller for controlling the drive unit and stimulators. Both stimulator channels must be turned OFF after the controller is powered up before either stimulator channel will operate. The drive unit is enclosed by a cover. When pressure on the cover is sensed, the controller stops and reverses the direction of the carriage. The drive unit includes a drive motor which is coupled to the carriage by a linkage. Limit switches provide limit signals when the linkage reaches predetermined limit positions. In response, the controller stops and reverses direction of the carriage. A remote patient controller which is coupled to the controller by a multiconductor cable permits the patient to control motion of the carriage from a remote location. Should the cable be disconnected from the controller, or should any lead therein become open or short circuited, the controller causes motion of the carriage to stop either immediately or after the remote patient controller is again actuated.
