The majority of adult devices have been designed for an individual to hold. However, it would be beneficial to provide users with a range of adult devices that support their use either in a hands free manner and/or are compatible with being worn by the user for varying periods of time from intermittent/occasional short durations through to extended wearing such as all day for example. In order to provide such wearable devices being able to separate the drive means from the stimulation means provides increased design flexibility as well as allowing different designs of adult device to be implemented as the design flexibility within the appropriate regions of the user's anatomy increases when the large vibratory motors are removed and connected to the stimulation means via flexible drive shaft. Further, beneficially, flexible drive shafts allow operation as the user moves during normal activities, such as sitting, standing, walking, etc.

A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is purposely sub-optimal for circulation at least some of the time, and especially when it is detected that the patient has regained consciousness. An advantage can be that the patient may thus faint again, and therefore perceive less of the unpleasant experience of the mechanical chest compressions that the CPR system continues to perform on them as it preserves them alive.

Provided is a walking assistance method and apparatus for providing an assistance torque to an ankle of a user. To provide an assistance torque to an ankle of a user, a first pressure value and a second pressure value are received from a first pressure sensor and a second pressure sensor, a ratio between the first pressure value and the second pressure value is calculated, a gain value is determined based on the ratio, an assistance torque value is calculated based on the ratio and the gain value, and a driver is controlled to output the assistance torque value.

Provided is a training device capable of executing a plurality of operation modes, in which an operation rod is appropriately operated according to an operation mode. The training device includes the operation rod, a plurality of motors, a plurality of force detection units, and a plurality of first command calculation units. The operation rod allows a limb to move. The plurality of motors operate the operation rod in the direction of degree of freedom in which the operation rod can move. Each of the force detection units detects a corresponding force component and outputs a force component signal. The first command calculation units are connected to the corresponding force detection units. Each of the first command calculation units calculates a first motor control command on the basis of the corresponding force component signal.

The present invention relates to an assisted rehabilitation system comprising a device with static-bicycle movement, and devices that automatically sense and manipulate body performance parameters, allowing the rehabilitation response process of a user to be optimised. In particular, the sensing devices measure the pedalling rate, the pedalling resistance and the user's pulse rate, allowing the optimum exercising range to be configured, depending on the data acquired from the patient and on the level of effort required from him or her. The system also comprises two motors. One motor drives a flywheel that allows the user to experience a variation in the pedalling rate while using the device. A second motor provides different levels of pedalling resistance, allowing muscular strength to be developed. When starting the activity, the user enters, on a touchscreen, the preliminary parameters for the desired pedalling rate and resistance level, which are analysed by a processing unit that calculates a suitable rehabilitation plan.
