Embodiments for systems and methods of a variable stiffness treadmill for gait rehabilitation using mechanical perturbations on the unimpaired leg to provide therapy to the impaired leg are disclosed.

A swimming wearable device comprises an upper body wearable device (100) and a lower limb wearable device (2). The upper body wearable device (100) comprises an electronic airbag (11) and the lower limb wearable device (2) comprises a muscle condition monitoring device (21). The muscle condition monitoring device (21) is connected by signal with the upper body wearable device (100) or with the electronic airbag (11) of the upper body wearable device (100). When detecting a muscle spasm in lower limb, the muscle condition monitoring device (21) sends a signal to the upper body wearable device (100) or the electronic airbag (11) of the upper body wearable device (100), so as to make the upper body wearable device (100) activate the electronic airbag (11) to open or to activate the electronic airbag (11) to open. The swimming wearable device can provide certain buoyancy for the swimmer at the occurrence of muscle cramp, thereby reducing drowning accidents and improve safety of swimming exercise. An upper limb wearable device is also provided.

The present disclosure provides a walk assist robot for lower body walking of a walking trainee, including a joint angle signal measurement unit disposed on a joint of the walking trainee, an electromyogram (EMG) signal measurement unit disposed on a muscle related to ankle joint extension of the walking trainee, a plantar pressure signal measurement unit disposed on a sole of the walking trainee, and a control unit to recognize signals measured from the joint angle signal measurement unit, the EMG signal measurement unit and the plantar pressure signal measurement unit and process the signals to recognize a walking speed intention of the walking trainee, wherein the control unit controls a walking speed of the walk assist robot from the walking speed intention of the walking trainee.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.

Provided is an apparatus for managing a player with a guard including a sensor sensing a vital information of a player to calculate an injury risk of the player to thereby manage a condition of the player, the apparatus including: a communication unit receiving the vital information from the guard and transmitting the injury risk to the guard; a memory storing a program calculating the injury risk to manage the condition of the player; and a processor connected to the communication unit and the memory to execute an operation implemented by the program, in which the program may include instructions using the vital information and pre-stored vital recovering ability data of the player to calculate the injury risk of the player.

The present invention pertains to a system and method for facilitating adaptive recentering in virtual reality (VR) environments capable of autonomously monitoring a user's viewpoint orientation within a VR environment using integrate sensors to detect deviations exceeding a predetermined threshold angle from a central reference point. The system employs an algorithm to evaluate the duration and extent of the user's viewpoint deviation, enabling detection of potential recentering needs without requiring direct physical input.

The invention relates to a method, an exercise device and a software for measuring maximum muscle strength value. Wherein, the method for measuring the maximum muscle strength value through an exercise device with dynamically variable resistance signal-connected to an arithmetic control unit, is obtained by performing the following steps. The steps include: an obtaining original muscle strength value step, an initial muscle strength value generation step and a maximum muscle strength value generation step. The characteristic of the present invention is that the maximum muscle strength value is obtained according to the position of the exercise process, which overcomes the shortcoming of traditional technology that can only obtain a single data. Moreover, the present invention further forms a maximum muscle strength curve, whereby the obtained data can be used in fitness training to effectively improve training effects and avoid muscle injuries caused by overloading.

An exercise machine for assisting a user in targeting a muscle for an exercise motion. A sensor detects a current use condition while the user performs the exercise motion. The current use condition is one of multiple use conditions. A current activation level of the muscle changes within the multiple use conditions. A control system is operatively coupled to the sensor and is configured to determine the current activation level of the muscle based on the current use condition detected by the sensor, receive a desired activation level of the muscle, and determine a recommended use condition within the multiple use condition to cause the muscle to be at the desired activation level for performing the exercise motion, and to notify the user of the recommended use condition and/or automatically cause the exercise machine based on the recommended use condition, respectively, to assist the user in targeting the muscle.

Provided is a weight exercise device. The weight exercise device includes: an exercise body in which a motion is generated according to a weight exercise of a user; a sensor configured to detect the motion of the exercise body; a display configured to output a user interface screen; and a processor configured to control the display to display, on the user interface screen, a first indicator indicating an exercise state of the user corresponding to the detected motion and a second indicator indicating an exercise guide that is recommended when exercising using the exercise body, wherein the processor is further configured to control the display such that a position of the second indicator is adaptively changed based on the exercise state of the user.

When controlling load torque of a drive unit on the basis of a biological signal detected from a subject's lower limb parts, adjustments are made to a hybrid ratio of voluntary control to generate running torque and a rotational speed of a crank according to the subject's intention and autonomous control to generate assisting power for the subject's pedaling motion on the basis of a rotation angle of the crank.
