Problems solved by technology

[0003] For the problem of medical rehabilitation, there are mainly the following current solutions: For example, Chinese invention patent 201710714823.4, a treadmill for medical rehabilitation is designed for patients to help patients exercise leg muscles, but this method cannot provide rehabilitation-related information during the exercise of patients. On the one hand, it is difficult to measure the degree of rehabilitation of patients, and on the other hand, it may cause patients to gradually lose interest in rehabilitation exercises in the process of rehabilitation without result feedback; for example, Chinese utility model patent 201820708380.8, with the help of upper limb dysfunction patients' upper limb dynamic Muscle strength feedback provides an upper limb function evaluation rehabilitation training system, but this method can only evaluate upper limb function, and its applicability is insufficient

example 1

[0090] Such as figure 1 As shown, the embodiment provides a quantitative evaluation system for human body balance function, which is composed of an acceleration sensing module M1, a body movement posture detection module M2, a display interaction module M3 and a balance ability evaluation module M4.

[0091] Step 1: Game initial parameter setting.

[0092] The user selects the initial parameters of the game by setting the initialization module M33. There are two initial game parameters that need to be selected, namely game mode and game difficulty. With the help of an external handwriting input board, the user selects the game mode parameter Mode1 and the game difficulty parameter Level1. In this mode, the user needs to wear the 5-way sensor group F i , (i=1, 2, . . . , 5) perform simple static aiming tasks.

[0093] Step 2: Wear the acceleration sensor group.

[0094] The user sets the 5-way acceleration sensor group F i , (i=1, 2, ..., 5) are respectively worn on the ab...

[0148] Such as figure 1 As shown, the embodiment provides a quantitative evaluation system of human body balance function, which is composed of an acceleration sensing module M1, a body movement posture detection module M2, a display interaction module M3 and a balance ability evaluation module M4.

[0149] Step 1: Game initial parameter setting.

[0150] The user selects the initial parameters of the game by setting the initialization module M33. There are two initial game parameters that need to be set, namely game mode and game difficulty. With the help of an external keyboard, the user selects the game mode parameter Mode1 and the game difficulty parameter Level2. In this mode, the user needs to wear the 5-way sensor group F i , (i=1, 2, . . . , 5) perform dynamic tracking aiming tasks.

[0151] Step 2: Wear the acceleration sensor group.

[0199] Such as figure 1 As shown, the embodiment provides a quantitative evaluation system of human body balance function, which is composed of an acceleration sensing module M1, a body movement posture detection module M2, a display interaction module M3 and a balance ability evaluation module M4.

[0200] Step 1: Game initial parameter setting.

[0201] The user selects the initial parameters of the game by setting the initialization module M33. There are two initial game parameters that need to be selected, namely game mode and game difficulty. With the help of a smart phone connected to the evaluation system through a local area network, the user selects the game mode parameter Mode2 and the game difficulty parameter Level1. In this mode, the user needs to wear a sensor group F 1 Perform simple static aiming tasks.

[0202] Step 2: Wear the acceleration sensor group.

[0203] The user sets the 1-way acceleration sensor group F 1 It is worn on the right ankle joint of ...

Abstract

The invention discloses a human body balance function quantitative evaluation system based on a feedback control process, the system is composed of an acceleration sensing module, a body motion posture detection module, a display interaction module and a balance ability evaluation module, a user executes a virtual aiming task to maintain a part of the body of a human body at a specific angle and orientation; meanwhile, the spatial position of a part of the body is detected through an acceleration sensor worn by a human body, and sensor data are processed by adopting a linear dynamics method and a functional network analysis method to obtain a real-time quantitative evaluation result of dynamic body feeling and a dynamic kinematic chain body weakness index. The system has excellent portability, can quantitatively evaluate the balance function of the upper and lower limbs and the core muscle group of the human body including the dynamic proprioceptive sensation and the dynamic kinematic chain body weakness index of the human body, and helps patients with body injury and postoperative body to estimate the self rehabilitation degree.

Description

technical field [0001] The invention belongs to the field of biomechanics, in particular to a quantitative evaluation system for human body balance function. Background technique [0002] Balance ability is the basic guarantee for the human body to perform functions such as standing and walking. From the perspective of biomechanics research, dynamically maintaining part of the body at a specific angle and orientation is a typical non-stationary and nonlinear feedback control dynamics process. Human body feedback control is a complex process involving multiple factors such as vision, proprioception, muscle and ligament strength. During the rehabilitation of patients with physical injuries and postoperative patients, the control of muscles and ligaments will gradually adapt to the new mechanical environment and physiological conditions. With the change of characteristics, the patient's balance ability gradually increased, and the patient's feedback control ability was also res...
