Description

Grid device for testing muscle strength of mice Technical Field The application belongs to the technical field of inverted grid experimental devices, and particularly relates to a grid device for testing muscle strength of mice. Background Muscle strength is a core element of human health and function, which not only determines our ability to perform daily activities, but also plays a vital role in athletic performance, disease prevention and rehabilitation. With lifestyle changes and aging population intensification, the maintenance and promotion of muscle strength has become an important issue in the global health field. In rehabilitation medicine, assessment and training of muscle strength is an important means to assist patients in restoring function. For example, in a rehabilitation process after a fracture or operation, enhancing muscle strength may accelerate recovery, reducing the occurrence of complications. In addition, muscle strength training is also widely used for preventing and treating sarcopenia, which is an age-related phenomenon of decreased muscle mass, severely affecting the quality of life and health life of the elderly. With the continued development of biomedicine, mice are becoming increasingly widely used as subjects and materials. They are useful for mimicking many human dyskinesias, including somatic and central nervous system diseases, the former involving more than thirty hereditary muscular dystrophies and myasthenia gravis, and the latter involving multiple sclerosis, spinal muscular atrophy, parkinson's disease, huntington's disease, and amyotrophic lateral sclerosis. For all these models, a comprehensive assessment of their motor deficits must include specific strength tests. The inverted grid test is to invert animals on a grid in a grasping manner and evaluate the strength and exercise coordination ability of the upper limbs. The experiment records the animal's performance and time on an inverted grid. This is a muscle strength test using all four limbs. Most normal mice readily acquire the highest score in this task, which is used to assess endurance or muscle fatigue before the muscle is rendered inactive. However, in the conventional inverted grid experiment process, when the test personnel test and monitor the experimental mice, since each grid device can only measure one mouse at the same time, most normal mice last for several minutes and tens of minutes, and in order to ensure that objective factors of the experimental mice are consistent, the test needs to be completed on all the mice in the same time period as much as possible, which results in excessive time cost. Therefore, an experimental device with convenience, reliability and large operation amount is needed. CN211185359U discloses a mouse inverted suspension instrument, which comprises an inverted suspension box body and a timer, wherein the inverted suspension box body comprises a base, a shell fixed above the base, and a drawer which is arranged in the base in a drawing manner, a cover plate is arranged on the movable cover at the top of the shell, an iron grid is movably hinged at the inner side of the cover plate, a partition plate is fixed below the iron grid, a plurality of experimental areas are arranged in the shell at intervals through the partition plate, a foam-rubber cushion is laid under each experimental area, a gravity sensing switch is arranged in the foam-rubber cushion, and the timer comprises a proximity switch arranged at the front side of the top of the shell, a timer display fixed at the front side of the shell, a language prompter and a power button which are arranged at the side surface of the base. According to the technical scheme, the mice are hung upside down through the iron grids, so that the foot grabbing force of the mice can be deeply utilized, the purpose of testing is achieved, and the tests of a plurality of mice can be simultaneously completed. Disclosure of utility model The application aims to solve the problems and provide a grid device for testing the muscle strength of mice, which adopts a multi-grid mode to realize the testing of a plurality of mice, and can timely supplement an idle testing area after the testing of individual mice is completed.
