Methods and systems for evaluating a pathological condition include acquiring movement information, such as electromyogram (EMG) information, and sleep disordered breathing (SDB) information, and detecting the presence of a pathological condition using both movement and SDB information. Methods may involve sensing physiological signals including at least muscle movement signals. Sleep-related disorders are detected using the sensed physiological signals, the sleep-related disorders including at least an involuntary muscle movement disorder and sleep-disordered breathing. Methods and systems also provide for detecting and treating a sleep-related disorder using movement and SDB information. Cardiac, respiratory, nerve stimulation, drug, or a combination of such therapies may be delivered to treat a detected or diagnosed pathological condition.

A system for three-dimensional (3-D) facial animation, including a base 3-D surface model representing a human face, and a set of displacement fields representing surface motion patterns associated with muscle movements. Each displacement field is a displacement vector varying over vertices of the base surface model and an intensity variable. Both the base surface model and displacement fields are acquired from a live subject by 3-D acquisition. The data are acquired using a surface acquisition system, capable of measuring the coordinates of a set of points on the subject's face and reconstructing the facial surface as a surface model. The base surface model is acquired by reconstructing the surface of the subject's face in the neutral pose. Each displacement field is acquired by reconstructing the surface of the subject's face in a series of poses of a muscle movement at increasing intensities. This results in a sequence of surface models exhibiting the changing shape of the face over the progress of the muscle movement. The displacement field is derived by calculating displacements at each selected intensity value and then interpolating over the known displacements.

A motion tracking system enables faithful capture of subtle facial and eye motion using a surface electromyography (EMG) detection method to detect muscle movements and an electrooculogram (EOG) detection method to detect eye movements. Signals corresponding to the detected muscle and eye movements are used to control an animated character to exhibit the same movements performed by a performer. An embodiment of the motion tracking animation system comprises a plurality of pairs of EMG electrodes adapted to be affixed to a skin surface of a performer at plural locations corresponding to respective muscles, and a processor operatively coupled to the plurality of pairs of EMG electrodes. The processor includes programming instructions to perform the functions of acquiring EMG data from the plurality of pairs of EMG electrodes. The EMG data comprises electrical signals corresponding to muscle movements of the performer during a performance. The programming instructions further include processing the EMG data to provide a digital model of the muscle movements, and mapping the digital model onto an animated character. In another embodiment of the invention, a plurality of pairs of EOG electrodes are adapted to be affixed to the skin surface of the performer at locations adjacent to the performer's eyes. The processor is operatively coupled to the plurality of pairs of EOG electrodes and further includes programming instructions to perform the functions of acquiring EOG data from the plurality of pairs of EOG electrodes. The EOG data comprises electrical signals corresponding to eye movements of the performer during a performance. The programming instructions further provide processing of the EOG data and mapping of the processed EOG data onto the animated character. As a result, the animated character will exhibit the same muscle and eye movements as the performer.

A handheld device for canceling unintentional muscle movement. The device includes a base comprising a handgrip for a user to hold, a gripping element linked to the base for releasably connecting the handheld device to an object, a sensor that detects movement of the base, a controller linked to the sensor, and at least one actuator that operates under control of the controller to cause movement of the gripping element in a direction that at least partially counteracts the detected movement of the base.

The present invention relates to a device and system to measure and assess superficial skeletal muscle mechanical and neuromuscular contractile characteristics, and interpret the results to provide metrics with quantifiable and qualitative descriptors relating to muscle function. The present device provides a further type of mechanomyography and a new use for acceleromyography by measuring the mechanical muscle movement of an involuntary stimulated muscle from an automated electro-stimulation protocol to determine muscle contractile properties. Muscle twitch response during the latent, contraction and relaxation phase is measured using an array of multiple accelerometers on a sensor pad to assess and diagnose muscle. function from various measurements. This information is processed using algorithms to determine muscle function abnormalities, muscle activation patterns, muscle symmetry of lateral muscle pairs, muscle synchronization of antagonist muscle, muscle force, muscle acceleration, muscle speed, muscle tone, muscle fatigue, muscle power/torque and muscle efficiency.

A universal fitness apparatus for force resistance, postural, and balance exercises. A flange assembly is coupled to a longitudinal shaft. The flange assembly can comprise receptacles for receiving handles or it can itself comprise handles. A user can support herself with the handles while performing a variety of exercises that target multiple muscle groups. The height of the handles can be adjusted by sliding the flange assembly along the shaft. Alternatively, the flange assembly and shaft can be mounted to a height adjustable runner coupled to a longitudinal track. A pin and/or lock to hold the flange assembly and/or runner at a particular height can be provided. The flange assembly can be rotationally coupled to the shaft so that the user can move the handles while performing oblique muscle movements. The receptacles and/or the handles can be pivotally movable such that the handles can be stored in an upright position.

The invention relates to the technical field of sports medicine and provides a muscle force assessment method and device and a muscle rehabilitation training tracking and assessment method and system. The muscle force assessment method includes the steps that image collection: ultrasonic equipment is adopted for collecting a muscle contraction image video in the moving process of a patient in real time; image preprocessing: framing is performed on the collected muscle contraction image video, so that interesting image information is extracted and the image contrast is adjusted; motion field extraction: a motion assessment method is adopted for calculating a motion field of every two adjacent frames in the image, and the motion fields represent spatial-temporal changes of an image gray value in the x direction and the y direction; a muscular movement range curve is obtained: a quantized index is extracted from the motion fields, and the muscular movement range curve is calculated in a fitting mode and serves as a reference standard of muscle force assessment. The ultrasonic equipment is used for collecting the muscle image, the muscle assessment method and device are simple and visual, requirements for a doctor and the patient are relatively reduced, and the processes of assessing muscle force are simplified.
