Methods and devices are provided for evaluating among the limbs of a subject the distribution of impairments of the subject's ability to coordinate the muscular contractions to execute effective postural movements. The subject may be placed on two independently movable support surfaces, either of which may be fixed or sway-referenced. The subject's ability to maintain his or her equilibrium position is then monitored. In another embodiment, the subject is perturbed from a position of equilibrium. The perturbation may be caused by a displacement of the support surfaces, or by having the subject grasp a handle, which may be moved, or against which the subject may push or pull. The latency and strength of the responses of the subject's limbs are measured and compared to each other and to a normal population.

Incapacitation of a mammalian subject results from the application of a pulsed, low-power electric waveform. The waveform is applied to the subject at a frequency and over a time period sufficient to induce involuntary muscular contraction. Additionally, the contraction causes limited lactic acid production and is non- or minimally-injurious to the subject's tissues. A device utilizing such a waveform is designed to control or otherwise subdue an individual.

An artificial muscle is composed of many artificial muscle fibre bunches. A single artificial muscle fibre bunch consists of double helical coils, elastic colloid and magnetic rheopectic liquid microball composed of magnetic rheopectic liquid carrier and polarizable magnetic particles. Its advantages are use of magnetic rheopectic effect to implement muscular contraction with strong contraction force, light weight and simple structure.

A method of same is also provided.

The invention discloses an artificial limb control method based on multiple sensor fusion, and relates to the technical field of artificial limbs. The artificial limb control method includes: by the aid of a first sensor, collecting electromyographic signals of spontaneous contraction of forearm muscles of an amputee; by the aid of the first sensor, detecting information of a second sensor and judging a wrist direction of an artificial limb of the amputee; triggering a camera device through muscular contraction after a wrist of the artificial limb is adjusted to a suitable grabbing posture, and shooting a grabbed object with the camera device; according to the grabbed objected shot by the camera device, determining a grabbing mode of the artificial limb by the aid of a third sensor, and controlling grabbing strength, for the object, of the artificial limb according to muscular contraction proportion of the amputee; ungrabbing the object through the muscular contraction by the amputee.The artificial limb control method based on multiple sensor fusion has the advantages that the amputee is enabled to control the artificial limb spontaneously and more naturally, no training is required, better experience can be obtained, and the artificial limb is more convenient to use.

The present invention relates to a method of increasing the intracellular concentration of phosphate by employing 2-(carbamimidoyl-methyl-amino)ethoxyphosphonic acid as vehicle and method to transport Phosphate into the cell. The increase in intracellular phosphate increases the availability of Adenosine Triphosphate and phosphocreatine, thereby leading to an increase in the anaerobic energy supply resulting in longer endurance and more forceful muscular contractions.

The invention provides a method for evaluating the steering control efficiency of a vehicle driver. The method comprises the following steps of: installing a steering sensor on a steering column of a vehicle to measure a steering force from the driver, attaching a muscle electrode to the shoulder muscle of the driver to collect a myoelectric signal of the shoulder muscle group of the driver, and establishing estimation equations of effective steering force and total steering force during steering control of the driver by regression analysis in combination with a model of relationship between the driver myoelectric signal and the muscular contraction force. The method achieves the purpose of evaluating the steering control efficiency of the driver and provides a theoretical basis for evaluating the steering comfort of the driver and the performance of the steering system. The method is suitable for the steering control of various vehicles and can be widely applied to the evaluation of driving comfort and steering system performance.

It is intended to provide an evaluation method and a screening method capable of eliminating a substance that disturbs in vivo kinetics in an individual and capable of simply and easily searching a substance having an action of activating/suppressing an innate immune mechanism without being affected by LPS derived from bacteria, which can be contaminated during the search, as well as a drug and a food for activating/suppressing the innate immune mechanism, and methods of producing the same. The present invention provides a method of evaluating or screening the substance having the action of activating/suppressing the innate immune mechanism using a muscular contraction of an organism having the innate immune mechanism as an indicator, and methods of producing the drug and the food for activating/suppressing the innate immune mechanism. Also, an innate immunity activator and the food having the action of activating the innate immune mechanism containing the substance having the action of contracting the muscle of the organism having the innate immune mechanism, and an innate immunity suppressor and the food having the action of suppressing the innate immunity containing the substance having the action of suppressing the contraction of the muscle of the organism having the innate immune mechanism are provided.

The present invention is dedicated to a calf exerciser including a foot unit having foot-palm and heel support surfaces. The foot unit provides efficient resistance training of calf muscles by permitting both eversion or inversion movements of the foot-palm in synchronization with the plantar flexion dorsiflexion muscular contraction. This is achieved by inclining the foot-palm support surface either towards the exterior or the interior sides of the foot unit, by anteo-posteriolly curving the heel support surface from the foot-palm surface to the bottom of the foot unit and by including a gradual inclination of the heel support surface towards the exterior or the interior sides of the foot unit, thus forming a variable angulation foot sole gradient area. This variable angulation foot sole gradient area accentuates the eversion and inversion movements at the foot-palm and reduces the biomechanical stress by eliminating coronal rotation at the heel.

The invention discloses pre-conditioned roast chicken with tender bamboo shoots and a preparation method thereof. Raw materials used in the invention are tender bamboo shoots and chicken. The preparation method comprises the following steps: pre-conditioning; rolling, kneading and pickling; stir-frying; sterilizing; packaging; and the like. The prepared pre-conditioned roast chicken with the tender bamboo shoots is not only soft in taste, but also elastic in meat quality. In the testing process of the invention, hawthorn juice is added for kneading and rolling of the chicken, so the problems of muscle contraction and muscle protein denaturation caused by reduction of the pH value of muscles in a non-living state are solved; the moisture content in the chicken is obviously improved; and thetaste of the processed chicken is improved. A hawthorn extract is added in a stir-frying stage, so DPPH. free radicals in the produced pre-conditioned roast chicken are effectively removed, the activity of lipohydrolase and lipoxygenase is inhibited, free fatty acid in grease is reduced, and the shelf life of the produced pre-conditioned roast chicken is obviously prolonged. The added hawthorn juice and hawthorn extract are purely natural substances, so the pre-conditioned roast chicken with the tender bamboo shoots disclosed by the invention is healthier and safer, is low in greasy feeling in eating, and better caters for the taste of the public.
