A load measurement device includes an acquisition unit, a first extraction unit, a second extraction unit, and an output unit. The acquisition unit acquires measurement information output from a load distribution sensor that detects a load distribution received from a sole of a subject. The first extraction unit extracts a region having a load value equal to or larger than a first threshold value as a first region based on the measurement information, and detects the first region as a sole region. The second extraction unit extracts a second region having a load value equal to or larger than a second threshold value that is smaller than the first threshold value from a re-extraction target region defined with the first region as a reference, and adds the second region to the sole region. The output unit outputs information related to a load distribution of the sole region.

A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.

A treadmill includes a frame; a running belt configured to rotate relative to the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, a user of the treadmill provides a force of rotation to the running belt. In a second operating mode, the motor is adapted to resist rotation of the running belt. In a third operating mode, the motor is adapted to provide a force of rotation to the running belt at a desired speed.

An electric treadmill includes a motor and a motor driving circuit. The motor driving circuit is operable to control electric current flow from a positive electrode through the motor to a negative electrode to drive the motor. The motor driving circuit has a switch path connected between the positive electrode and the negative electrode. The switch path has a resistance element and a switch element connected in series. When the motor driving circuit receives power from the external power source, the switch element will automatically switch to an open state so that the resistance element is inactive; and when the motor driving circuit does not receive power from the external power source, the switch element will automatically switch to an closed state so that the resistance element is operated to provide a resistive load for stopping rotation of the endless belt.

A balance training system including a mobile plate configured to support a sole of a trainee in a standing state, a first member fixed on the mobile plate, a load distribution sensor including a plurality of sensors arranged in a matrix under the mobile plate and configured to detect a load received from the trainee riding on the mobile plate and a position of the first member, and a control unit configured to calculate a net moving amount of a center of gravity position of the trainee based on a difference between a moving amount of a center of gravity position of the load received from the trainee detected by the load distribution sensor and a moving amount of the position of the first member detected by the load distribution sensor and to control a movement of the mobile plate based on a result of the calculation.

A method for unlocking a control unit of an exercise machine includes providing the exercise machine, having at least one sensor for detecting presence of a user on the exercise machine, with at least one electrical signal representative of a detection carried out at the time of the occupation of the exercise machine by a user. The method further includes switching, by the exercise machine, the control unit of the exercise machine from a first locking condition to at least a second operating condition in which the user may issue commands to the exercise machine by the control unit, based on the at least one electrical signal provided by said at least one sensor for detecting the presence of the user on the exercise machine.

A treadmill according to the present invention includes: a frame; an endless belt; an endless-belt drive unit; a plurality of cameras provided on the frame such that the orientations and/or locations thereof can be adjusted; a motion-data acquisition unit that markerlessly acquires motion data of a subject by using image information obtained with camera images; a motion analysis unit that analyzes the motion of the subject by using the motion data; and a control unit that controls the endless-belt drive unit based on the motion data.

A motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a current sensor coupled to the motor, and a controller in communication with the motor and the current sensor. The current sensor is configured to detect a motor current of the motor when using the motorized treadmill. The controller is configured to analyze fluctuations of the motor current to determine whether objects or children interfere with rotation of the endless belt. When the current sensor detects a current change does not associated with the user of the motorized treadmill, the controller determines that the endless belt is interfered by objects or children and stops operation of the motor to slow or stop rotation of the endless belt.

A method determines running phases of a user on a treadmill having first and second rotating elements rotating about respective rotational axes transverse to a longitudinal axis of the treadmill. A physical exercise surface connects to the rotating elements. An electric motor operatively associated with one rotating element rotates the rotating elements and the physical exercise surface. A processor connects to the electric motor and controls the electric motor. The processor determines a magnitude variable over time, which is correlated to user interaction with the exercise surface while exercising and has a periodic trend. The processor determines time instants of at least two points of the periodic trend. The time instants of each point representing instants of user interaction with the exercise surface. The processor determines a running phase of the user on the exercise surface as a function of the respective time instants of the periodic trend.

The walking training system includes: a treadmill; a determination unit configured to determine whether a walking of the trainee on the treadmill is an abnormal walking based on predetermined abnormal walking symptoms; a display unit configured to display a result of a determination of each of the abnormal walking symptoms; a reception unit configured receive a selection of at least one result of the determination from the results of the determinations, each of which displayed on the display unit, in which regarding pieces of advice about adjustment items for improving the abnormal walking symptoms in the result of the determination which the reception unit has received the selection, the display unit preferentially displays the pieces of advice that are common to pieces of advice about adjustment items for improving the abnormal walking symptoms in a result of another determination in which the determination unit determines the abnormal walking.
