Embodiment 1

[0022] According to an embodiment of the present invention, a method for evaluating the comfort of a prosthesis receiving cavity is provided, such as figure 1 As shown, the method includes:

[0023] Step S102, collect historical motion state data of the prosthesis wearer, and perform data preprocessing on the collected historical motion state data to establish a data set.

[0024] In an exemplary embodiment, the posture data of the prosthetic wearer's walking, going upstairs, downstairs, sitting and standing are collected through the inertial sensing unit arranged on the receiving cavity of the prosthesis; The plantar pressure sensor on the sole of the prosthesis receiving cavity collects gait data during the walking process of the prosthesis wearer, wherein the gait data includes data of two stages of leg support phase and swing phase, so The support phase is a walking phase that begins with the heel strike of the prosthesis wearer and ends with the toe-off, and the swing ph...

Embodiment 2

[0033] According to an embodiment of the present invention, another method for evaluating comfort of a prosthesis receiving cavity is provided. Such as figure 2 As shown, the method includes the following steps:

[0034] Step S201, collecting data.

[0035] A large number of prosthetic wearers were tested under different motion states.

[0036] The posture data of the prosthetic wearer walking, going up stairs, going down stairs, sitting and standing are collected through the inertial sensing unit set on the prosthesis receiving cavity.

[0037] The gait data during walking is collected through the plantar pressure sensor arranged at the plantar position of the prosthetic limb receiving cavity, wherein the gait is composed of two phases: a leg support phase and a swing phase. Such as image 3 As shown, the stance phase is the gait stage that begins with the heel strike and ends with the toe off the ground. In this stage, the support leg keeps in contact with the ground, a...

Embodiment 3

[0075] The present application also provides a method for evaluating the comfort of the prosthesis receiving cavity, such as Figure 5 As shown, the method includes the following steps:

[0076] Step S501, data collection.

[0077] The posture data of the prosthetic wearer walking, going up stairs, going down stairs, sitting and standing are collected through the inertial sensing unit set on the prosthesis receiving cavity. The gait data during walking is collected by a plantar pressure sensor arranged at the plantar position of the prosthetic limb receiving cavity. The pressure data of the patient on each position of the inner wall of the prosthetic cavity during the movement is collected through the cavity pressure sensor in the prosthetic cavity.

[0078] Step S502, creating a data set.

[0079] Perform operations such as data preprocessing and feature value selection on the collected data, such as attitude data, gait data, and pressure data, to establish a data set.

Abstract

The invention discloses a comfort assessment method and device for an artificial limb socket and a storage medium. The method comprises the following steps: acquiring historical motion state data of an artificial limb wearer, and performing data preprocessing on the acquired historical motion state data to establish a data set; setting network parameters of a CNN network, and performing convolution calculation and pooling calculation based on the data set to generate a CNN network model; taking one part of the data set as a training set, taking the other part of the data set as a test set, performing sample training on the CNN network model by using the training set, and testing the CNN network model by using the test set; and evaluating the comfort level of the worn prosthetic socket based on the trained and tested CNN network model. The technical problem that the patient experience is seriously affected due to insufficient wearing comfort of a patient caused by a fixed artificial limb receiving cavity structure is solved.

Description

technical field [0001] The invention relates to the field of smart wear, in particular to a method, device and storage medium for evaluating the comfort of a prosthesis receiving cavity. Background technique [0002] In recent years, the number of calf amputee patients has been increasing, because the inconvenience of movement not only brings a serious burden to the family, but also makes them gradually lose confidence in life. [0003] However, with the development of science and technology, the level of prosthetics is also constantly improving. The current commercial intelligent bionic prosthetics can significantly improve the walking gait of amputees and greatly help them resume daily activities. Fixation leads to insufficient wearing comfort for patients, which seriously affects patient experience. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] Embodiments of the present invention provide a method, dev...
