Description

Muscle tension tester and muscle tension testing method

Technical Field

The invention relates to the technical field of skin and muscle tension measurement, in particular to a muscle tension tester and a muscle tension testing method.

Background

Muscles are important components of the human body, and various physiological activities of the human body are realized by the participation of the muscles, so that the injury or disease of the muscles can seriously affect the normal life of the human body. Dystonia is a common manifestation of many neurological and muscular diseases, and evaluation of muscular tension is critical for making a treatment plan and evaluating the treatment effect.

Muscle tone refers to the resistance felt by the active limb or pressing against the muscle, which is created by physical properties of the tissue, elasticity within the muscle or connective tissue, reflex muscle contraction, etc. Lesions on nerve-muscle reflex arcs, contractures of tendons, joint stiffness and the like all affect the examination results of muscle tension, and the detection of the muscle tension should be performed in a warm environment and in a comfortable posture, so that a tested person can relax as much as possible.

The most commonly used method for evaluating the muscle tension in clinic is to modify the Ashworth scale, and the method is simple and easy to implement, but the result is greatly subjectively influenced by a tester. The isokinetic exercise tester method can objectively and quantitatively evaluate the cramp, but cannot be widely applied in clinic due to complex operation and huge equipment. The skill muscle tension assessment is to sense the tension degree of the muscle according to the pinching of the muscle to be tested by self experience and judgment, and the method is also greatly influenced by the subjective influence of a tester and has no unified standard.

With the progress of the technology, new devices for detecting the muscular tension, such as detection technologies named as "a muscular tension measuring instrument" (bulletin number CN 203776916U), "an upper limb muscular tension measuring device" (bulletin number CN 104622848A), "a muscular tension detecting apparatus and system" (bulletin number CN 204147049U), "a muscular tension measuring device (bulletin number CN 202426537U)," a muscular tension detecting analysis apparatus and detection method "(bulletin number CN 1077026A)," a foot muscular tension quantitative detector "(bulletin number CN 201710367U), a skin muscular tension measuring device (bulletin number CN 102125436A), a muscular tension disorder detector (bulletin number CN 106974664A), and the like, appear, and these measurement devices and methods, although improving the accuracy of the muscular tension detection, reduce the subjectivity of the detection result, have a number of disadvantages in the prior art including the above disclosed technology. For example, the "an upper limb muscular tension measuring device", "a foot muscular tension quantitative detector" and "a muscular tension detecting device and system" have the special parts such as limbs or feet and the like, and the measurement accuracy is insufficient, the operation is very complex, and the application is very inconvenient; although the ' a muscle tension measuring instrument ', a muscle tension measuring device, a muscle tension detection analysis device and a muscle tension detection method ' are improved, the measuring device is complex, the cost is high, and the requirement on measuring personnel is high, so that the improvement is needed.

When a predetermined pressing force acts, the mounting column 121 moves axially downwards, so that the pressure transmission element 160 is driven to further drive the skin contact element 140, the circular skin contact body 141 is pressed in the direction of the muscle, and the circular skin contact body 141 is in surface contact with the skin due to the arrangement of the circular skin contact body 141, so that the stress consistency of the measurement surface can be ensured and the measurement accuracy can be improved because the influence of the surface state of the skin is less compared with a measurement head which forms point contact.

When the muscle tension test handle 100 of the present invention is used, a user holds the main body housing 110 and applies a certain pressing force to the muscle vertically downwards, during this process, the mounting post 121 moves axially downwards, so as to drive the pressure transmission element 160 and further drive the skin contact element 140, so that the circular skin contact body 141 is pressed in the direction of the muscle, and meanwhile, the applied pressing force is transmitted to the force measurement spring 133 through the pressure transmission element 160 and the mounting post 121, at this time, one of the signal processing boards and one of the sensors (such as the first sensor 1223 and the first signal processing board 1221) of the circuit module 122 senses a relative displacement change (the relative displacement change corresponds to the deformation of the force measurement spring 133), and the pressure value born by the force measurement spring 133, namely, the "force" in the force-displacement "in the following text) can be obtained through the deformation of the force measurement spring 133, so that the control module 200 converts a real-time voltage analog signal into a digital signal and intercepts the measured effective voltage signal data according to a calibrated data range in advance; at the same time, the base 151 is still fixed on the skin surface and is kept stationary, so that an axial relative movement is generated between the sleeve 152 and the limit rod 153 and the mounting post 121, and one of the signal processing boards and one of the sensors (such as the second sensor 1224 and the second signal processing board 1222) of the circuit module 122 senses a relative displacement change (the relative displacement change may obtain a "displacement" in a "force-displacement" hereinafter) between the limit rod 153 and the mounting post 121 and converts the relative displacement change into a voltage signal output, so that the control module 200 converts a real-time voltage analog signal into a digital signal and intercepts the measured effective voltage signal data according to a predetermined data range; the control module 200 processes the acquired force-displacement signals of the muscles, transmits the processed force-displacement signals to the PC 300 through serial communication, and generates force-displacement curves and related data files of the muscles after processing the force-displacement curves by built-in software. When the data test is completed, the muscle tension test handle 100 is gently lifted, the skin contact element 140 is separated from the skin surface, the base 151, the sleeve 152 and the limit lever 153 return to the initial state under the action of gravity and the return spring 170, and the guide groove 161 can perform guiding and limiting functions in the return process.

The control module 200 of the muscle tension tester of the invention is independent of the PC 300, and can also be integrated on the host of the PC 300.

The measuring process of the muscle tension tester comprises the following steps: after all connections are ready, the muscle belly is vertically pressed by the muscle tone test handle 100, and at this time, the inner core (i.e., the force measuring part) of the muscle tone test handle 100 is always pressed down, the circular skin contact body 141 at the lower end of the muscle tone test handle 100 is held on the skin surface, and a relative displacement change occurs between the cylindrical rod 132 and the mounting post 121, which corresponds to the "force"; meanwhile, the relative displacement between the limit lever 153 and the mounting post 121 changes, the relative displacement changes correspond to the displacement, and due to the arrangement of the comparison module, the invention can be set to collect the change relation between force and displacement in the process of gradually applying force from 0 kg to 2kg in the pressing process, and when the force applied by the force sensor is detected to reach 2kg, the measurement is ended.
