Biodynamic apparatus for performing correct SIT-UP and LEGS-UP exercises and methods

InactiveUS20060116262A1Good flexibilityEffectStiltsFlexibility exerciseLumbar
A biodynamic apparatus to perform correct, safe and effective SIT-UP and LEGS-UP exercises and simultaneously perform spinal arching, spinal decompression, and flexibility exercises, comprising of two part frame hinged at one end and a set of parallel bars that elevate and anchor the legs of the user concentrating the exercise in the abdominal area of the body. The main feature of the apparatus is provided by a device the inventor calls “flexor”. The flexor is not an ordinary lumbar support. Its function is to meet the natural fulcrum of the human torso, which is below the sacrum, to safely and efficiently articulate. Most exerciser bend the spine during the exercise, rather than the pelvis putting a tremendous negative stress on the vertebra and on the intervertebral discs. With the help of the “Flexor” the torso can move from horizontal to at least 90 degrees angle as one straight piece, free from the gravitational stress produced on the spine, especially on the cervical vertebra, by the weight of the head during the initiation of the exercises. It is a fact that ordinary SIT-UP and LEGS-UP exercises the work is performed for the most part by the neck, back and lumbar muscles during the first part of the movement placing a dangerous negative stress on the spine, and especially on the spinal cord. With the use of this apparatus, the reverse can be observed. The user by lying on the “flexor” places in traction the entire set of abdominal, pectoral and neck muscles creating a direct line of force between the abdomen and the head. The spine is arched and decompressed, the abdominal muscles are in traction and the lumbar muscles are neutralized since there are bent beyond their working point. This position of the body allows to safely concentrate 100% the force on the abdominal muscles to initiate the primary work constituted by the lifting of head of the user, instead of the neck, and on the lumbar muscles of the user, as well as to protect the spine and the weak abdominal muscles from negative stress and subsequent short and long term injuries. Decompression, arching, and flexibility of the spine, being achieved during this new method of performing SIT-UP and LEGS-UP exercises, simultaneously, make this apparatus bio-dynamically correct, as far as distribution, compensation and equalization of stresses; meet the scientific principles of muscle dynamics of traction and contraction; protect the spine from negative stress, especially the weak cervical and lumbar areas; maintain and enhance the spine's integrity and flexibility; and obtain maximum abdominal muscle developments, which are the major benefits of this invention. The flexor is mounted on two external parallel railing as to adjust to the length of all users. It also has an internal adjustable mechanism that allows its two padded flanges to adjust in width to accommodate all waist sizes of users for additional support and prevention of lateral stress to the lower spine.

Multi-channel hand myoelectric acquisition wrist strap based on fabric electrode

The invention relates to a multi-channel hand myoelectric acquisition wrist strap based on a fabric electrode. Differential electrodes and a reference electrode are uniformly arranged on the wrist strap; the differential electrodes and the reference electrode are located on the portions, slightly close to the wrist, in the middle of the forearm. If the differential electrodes and the reference electrode are too close to the wrist, the electrodes are away from the muscle belly, and the signal intensity is low. If the differential electrodes and the reference electrode are too away from the wrist, the resolving power of the electrodes on finger movements is not strong. The center distance between every two differential electrodes is not larger than 30 mm, and if the distance is selected to be too large, too many effective frequency components of myoelectric signals are lost. The differential electrodes are distributed in pairs, the number of the pairs is n, and the differential electrodes correspond to four muscle groups related to hand movements. The rectangular reference electrode is arranged in a non-muscle activity area as much as possible, and the reference electrode is used forproviding null voltage reference, so that the signals are stable as soon as possible. The wrist strap is light, convenient to use and comfortable to wear; due to the characteristics of the fabric electrode, skin does not need to be pretreated or coated with conductive paste for collection, and the wrist strap is suitable for long-term collection.

Stapedius muscle electrode

The invention relates to a stapedius muscle electrode array for detecting the action elements generated when a human stapedius muscle is contracted. Said array comprises an electrode (2, 2′, 2″) that is adapted for bipolar discharge and is to be attached to a human stapedius muscle. The electrode has two flexible, elastic, electrically conducting elongate elements (2a, 2b), each of which has a distal (4a, 4b) and a proximal end (17a, 17b) and is helically preshaped along at least some of the length thereof to the distal end (4a, 4b) thereof in such a way that the distal end (4a, 4b) and a section of the respective elongate element (2a, 2b) which adjoins the distal end (4a, 4b) can be placed at least in part around the tendon (7) extending between the stapedius muscle and the stapes while the helical part can be guided along the tendon (7), can be moved in the direction of the stapedius muscle, and can be at least partly twisted into and / or slid onto the region of the muscle belly (6) adjoining the tendon (7). The two elongate elements (2a, 2b) are electrically insulated from one another, and the helical parts (3) thereof are intertwined in such a way as to run around a common centerline (11), allowing the helical parts (3) to be jointly placed around the tendon (7), be guided along the tendon (7), and be brought in contact with the stapedius muscle.

Method for measuring TMS movement threshold in mouse waking state

The invention discloses a method for measuring a TMS movement threshold in a mouse waking state. The method comprises the following steps: performing 2-3 minutes of anesthesia on a mouse by using a suction-type gaseous anesthesia mode; placing the anesthetic mouse on a bracket, and constraining and fixing the mouse on the bracket through a self-adhering bandage, wherein a height of the bracket isgreater than a length of front and rear limbs of the mouse, enabling the limbs of the mouse to be suspended and keeping a relaxing state; barbering around a target muscle of the limbs of the mouse, exposing a muscle belly and a muscle tendon of the target muscle, and pasting a surface myoelectricity measuring electrode and a grounding electrode; in the waking state of the mouse, enabling a TMS pulse to act on a mouse movement cortex, through observing mouse limb movement or through analyzing a movement evoked potential in a surface electromyogram signal at the target muscle, completing measurement of the TMS movement threshold in the mouse waking state. The method is capable of measuring the TMS movement threshold in the mouse waking state. The TMS movement threshold in the waking state ismore helpful to accurately set TMS stimulus intensity in a mouse TMS experiment compared with the TMS movement threshold in an anesthetic state.
