DETAILED DESCRIPTION OF THE INVENTION
Definitions
[0037] For helping the Examiner further realize and recognize the present application, some detailed descriptions and preferred embodiments are described as follows:
[0038] Given that the conventional gait activity assistance system has many insufficiencies and limitations, like the conventional gait activity assistance system cannot induce user to have the effect of self-learning, or user can only rely on the operation of the device to imitate the motion. Besides, the force points of the conventional gait activity assistance system provide user with no correct sensory input, so that it is impossible to simulate the training method of physical therapists in performing NDT and adjust the auxiliary parameters for user in time according to user's movement. On these grounds, the present invention provides a gait activity learning assistance system and the application method thereof, it can (1) drive user's limb to swing or rotate by a interlocking unit to achieve the purpose of inducing or guiding user to learn gait activity autonomously; (2) detect the change in user's limb movement and record the process of physical therapist performing NDT by a movement detecting module; (3) measure dynamic change in the interlocking unit by a dynamic measurement module while user strides and send the change back to a control module immediately to process motor algorithm simultaneously, so the driving force execution timing signal of a motor, the forcing strength signal, the forcing duration information, the displacement information can be adjusted by user's need. Therefore, the present invention can mimic the rehabilitation strategy of physical therapist and provide a substitute way to replace the human resource of physical therapist in physical medicine and rehabilitation.
[0039] Therefore, the present invention provides a gait activity learning assistance system, including at least one movement detecting module which detects the change in movement of user's limb and obtains at least one movement characteristic data as a basis for said system to evaluate the state of user's gait; at least one control module that receives, analyzes and calculates at least one movement characteristic data to give a command for a driving module to drive the limb of user to swing or rotate to at least one site, so that user can be induced or guided to learn the gait activity spontaneously; and at least one dynamic measurement module, which is connected to at least one interlocking module, measures a dynamic change in the interlocking unit while user strides and obtains at least one dynamic characteristic data which is sent back to the control module for processing motor algorithm, so that the control module can adjust the timing, forcing strength, forcing duration or driving site immediately to allow user to retrain the brain through somatic perception instead of simply mimicking the movement of standard process.
[0040] According to above reasons, the following descriptions demonstrate the present invention comprising elements, features, and their combinations or communications.
[0041] First of all, refer to the
[0042] As mentioned above, the movement detecting module detects the change in user's limb and then analyzes the change to define to generate a movement characteristic data. The movement detecting module is an optical sensing unit, an inertial sensing unit or a combination thereof. Therefore, the movement detecting module comprising an image capturing unit, a body motion tracking unit, a distance measurement unit, a distance scanning unit, an inertial measurement unit or a combination thereof, and the number of the movement detecting module in said system is in demand to be one or multiple. After the movement detecting module analyzes the change in the limb of user, the movement characteristic data, including stance phase duration, swing phase duration, double-limb support phase duration, the time of heel strike, the time of foot flat, the time of heel off, the time of toe off, foot strikes, hip angle, knee joint angle, hip joint position, ankle angle, number of steps per unit time, walking distance per unit time, step length of the healthy side, step length of the affected side, stride length, step width, foot angle, gait symmetry, change in balance, body alignment, base of support, ratio of the stance phase to the swing phase on the same side, ratio of the stance phase to the swing phase on the different sides, percent of the time of each stage in stance phase, or any combinations thereof, is obtained. Thus, the movement detecting module is capable of analyzing any change in limb, and recording the change in said system as the movement characteristic data to establish a personal database of gait activity learning process. And furthermore, the movement characteristic data is sent back to the control module to provide the driving module with suggestion of force timing and force strength.
[0043] Refer to the
[0044] Back to the
[0045] Besides, the interlocking unit is disposed on at least one limb position where is able to make user's limb swing or rotate, so that the interlocking unit has to possess enough structural strength and elasticity to support user and provide a buffer to ease the uncomfortableness, and to be able to swing or rotate with user while the motor drives. According to above reasons, the interlocking unit can be an elastic belt, but it's alternative.
[0046] In one embodiment of the present invention, the number of the interlocking unit depends on how many limb positions are considerate to allow user's limb swing or rotate. The limb position comprises a pelvic region, a posterior sacral region, a distal segment of the limb, muscles of the abdomen and any combinations thereof. The interlocking unit provides pelvic region or posterior sacral region with a forward force on the tangent direction of the pelvic region to drive the pelvic region or posterior sacral region to move forward or rotate. In addition, if the interlocking unit forces on the distal segment of the limb, the upper limb or the lower limb of user is guided to swing autonomously because the distal segment of the limb has a longer arm of force from joint. Furthermore, if the interlocking unit forces on muscles of the abdomen, the muscles of user are stimulated to contract. Hence, when user rotates limb, swings limb, contracts muscle or any combinations thereof, user is motivated or induced to control the lower limb autonomously to correspond with said system to give a response through perception. By the interlocking unit of said system to guide the user continuously, the purpose of relearning to control muscle and limb is achieved to help elevate the therapeutic effect of neurodevelopment.
[0047] Also, refer to the
[0048] The dynamic change in the interlocking unit, comprising the forcing strength, the position, the duration while the interlocking unit drives user, is sent back to the control module immediately for analysis to obtain the dynamic characteristic data. Based on the dynamic characteristic data, the motor algorithm is processed to generate the second control signal. In one embodiment of the present invention, a process diagram of motor algorithm, as shown in
[0049] Step S10: setting up a default to a motor;
[0050] Step S12: verifying if a heel is on the ground;
[0051] Step S14: verifying if the location of the heel is in front of the other heel;
[0052] Step S16: verifying if the heel is on the ground again;
[0053] Step S18: generate a second control signal.
[0054] In the step S10 of the above process, the default is an initial action force that does not move the at least one interlocking unit. In one preferred embodiment of the present invention, the default is 0.5 to 1.5 lb. In the step S12, the processing unit verifies if the heel is on the ground. If the heel is off the ground, the motor will stay to provide the default only. On the contrary, if the heel is on the ground, another verification, the step S14, will be processed to verify whether the location of the heel is in front of the other heel or not. Likewise, if the location of the heel is behind the other heel, the motor will stay to provide the default. In contrast, if the location of the heel is in front of the other heel, the other verification, the step S16, will be processed to verify whether the heel is on the ground again or not. If the heel is off the ground, the motor will go back to provide the default to avoid over exerting on user. If the heel is on the ground, a second control signal will be generated, as the step S18 indicates, to the motor driver of the driving module for driving the motor continuously.
[0055] The second control signal comprises a driving force execution timing signal of the motor, a forcing strength signal, a forcing duration information, a displacement information of the at least one limb position or any combinations thereof. In one preferred embodiment of the present invention, the trajectory value range of the driving force from the motor is between 0.5 to 6 lb to drive the interlocking unit, so that the pelvic region, the posterior sacral region, the distal segment of the limb, the muscles of the abdomen or any combinations thereof of user is moved along with the interlocking unit. Therefore, through detecting the dynamic change in the interlocking unit by the dynamic measurement module, the timing, the force strength and the duration of the interlocking unit while drives user are adjusted accurately. Also, the displacement of the limb position can be adjusted to increase or decrease, so that it can be decided to drive which body parts. By reproducing the rehabilitation assistance from physical therapist by said system, user can be guided to perform the gait activity accurately at the right timing and avoid to be over exerted. And said system provides user with more accurate sensory input to elevate the effect of learning the gait activity autonomously and to achieve the purpose of therapeutic effect in neurodevelopment.
[0056] In
[0057] Aforesaid gait activity learning assistance system is personalized by the following applications to attain the therapeutic effect in neurodevelopment:
[0058] Refer to the
[0059] Step S20: disposing at least one interlocking unit on at least one limb position;
[0060] Step S21: detecting a displacement of user's limb to generate at least one movement characteristic data by at least one movement detecting module while user walking;
[0061] Step S22: forming a control signal calculated by a control module which receiving the at least one movement characteristic data, and transmitting the control signal to a motor driver of at least one driving module;
[0062] Step S23: turning the control signal to a motor driving signal by the motor driver of the at least one driving module, and transmitting the motor driving signal to a motor to generate a driving force correspondingly;
[0063] Step S24: driving at least one limb position of user by the driving force of the motor to make the user's limb swing or rotate and guide user to process a gait reaction;
[0064] Step S25: measuring a dynamic change of at least one the interlocking unit by at least one dynamic measurement module to obtain at least one dynamic characteristic data which is sent back to the control module immediately to process a motor algorithm for obtaining a second control signal, wherein the second control signal is comprising a driving force execution timing signal of the motor, a forcing strength signal, a forcing duration information, a displacement information of the at least one limb position or any combinations thereof;
[0065] Step S26: driving the at least one interlocking unit to drive the at least one limb position of user to make the user's limb swing or rotate before the user process a gait reaction by the motor driver and motor which is driven by the second control signal to guide user process a correct gait reaction.
[0066] In this embodiment of the present invention, as the step S20, user can put the interlocking unit on the key point body part, like the pelvic region, the posterior sacral region, the distal segment of the limb, the abdomen and any combinations thereof, to provide a right action force that allows limb to swing or rotate. The interlocking unit is an elastic belt, and it provides pelvic region or posterior sacral region with a forward force on the tangent direction of the pelvis to drive the pelvic region or the posterior sacral region to move forward or rotate. In addition, if the interlocking unit forces on the distal segment of the limb, the upper limb or the lower limb of user is guided to swing autonomously because the distal segment of the limb has a longer arm of force from joint. Furthermore, if the interlocking unit forces on the abdomen, the muscles of user are stimulated to contract.
[0067] Next, as the step S21, the movement detecting module, an optical sensing unit or an inertial sensing unit, detects the change in user's limb while user operates stride action, and then analyzes the change to define and generate a movement characteristic data. Therefore, the movement detecting module comprising an image capturing unit, a body motion tracking unit, a distance measurement unit, a distance scanning unit, an inertial measurement unit or a combination thereof in demand. After the movement detecting module analyzes the change in the limb of user, the movement characteristic data including stance phase duration, swing phase duration, double-limb support phase duration, the time of heel strike, the time of foot flat, the time of heel off, the time of toe off, foot strikes, hip angle, knee joint angle, hip joint position, ankle angle, number of steps per unit time, walking distance per unit time, step length of the healthy side, step length of the affected side, stride length, step width, foot angle, gait symmetry, change in balance, body alignment, base of support, ratio of the stance phase to the swing phase on the same side, ratio of the stance phase to the swing phase on the different sides, percentage of the time of each stage in stance phase, or any combinations thereof is obtained.
[0068] And as step S22 to S24 indicating, the control module receives and analyzes at least one movement characteristic data to generate the control signal which is sent to the motor driver of the driving module. The motor driver receives the control signal and turns it into the motor driving signal, sent to a motor to generate the driving force to drive the interlocking unit, and the interlocking unit moves user at least one limb position to make user swing, rotate, or construct, so that user can be induced to operate stride action.
[0069] As step S25, while user operates stride action, the at least one dynamic measurement module measures the dynamic change in the at least one interlocking unit immediately and then generates at least one dynamic characteristic data which is sent back to the control module for processing motor algorithm, so that the force condition of the interlocking unit, like execution time, force strength, force duration, can be adjusted according to the condition of the user's gait activity. In this way, user is protected from being over exerted by the interlocking unit and induced to control limb for corresponding action autonomously by perception and cognition. Briefly, said system provides user the sensory input and a cycling rehabilitation to meet the need, and induces user to relearn the control of limb and muscle.
[0070] Additionally, said system simulates the rehabilitation of physical therapists and records it in said system for repeating the same treatment to be a personal pad assisting mode of gait activity learning assistance. Refer to the
[0071] Step S30: disposing at least one interlocking unit on at least one limb position;
[0072] Step S31: providing a gait assistance which applied on the at least one limb position of user while user walking;
[0073] Step S32: detecting a displacement of user's limb by at least one movement detecting module while user receiving the gait assistance to generate and to record at least one movement characteristic data, and measuring a dynamic change of the at least one interlocking unit by at least one dynamic measurement module while user receiving the gait assistance to obtain and record at least one dynamic characteristic data;
[0074] Step S33: repeating providing a gait assistance step and detecting step at least two cycles to obtain the force information of gait assistance including the at least one movement characteristic data and the at least one dynamic characteristic data, saving them in the system to establish a gait activity learning instruction.
[0075] In the step S30 and S31 of this embodiment, the gait activity assistance is for giving a right sensory stimulation on key point of limb at the right timing while user walks. To achieve the therapeutic effect in neurodevelopment, the gait activity assistance guides user to induce a movement or construct muscles for making a right gait activity. To be more precise, the gait activity assistance is the manual rehabilitation performed by physical therapists, comprising a thrust force, a tension force, a resistance force, a support force, a slap force or a touch force. And the manual rehabilitation is applied on the pelvic region, the posterior sacral region, the distal segment of the limb, the muscles of the abdomen and any combinations thereof. A dynamic change, which is strength, time or position, in the interlocking unit is measured accurately by at least one dynamic measurement module because the interlocking unit is connected to at least one dynamic measurement module and disposed on at least one limb position. In this way, the gait activity assistance detects and analyzes the change in limb and the interlocking unit by the at least one movement detecting module and at least one dynamic measurement module respectively to define at least one movement characteristic data and dynamic characteristic data for developing a gait activity learning instructor. And the gait activity learning instructor is saved in said system to be processed in demand of user for re-performing the manual rehabilitation of the physical therapists, so that it is a substitute or an assistant strategy for rehabilitation.

The image sensing device is an active capturing system to paste the active photosphere on key points of user's limb, which includes four sides of lumbar joint, left or right thigh, left or right calf, left or right ankle, left or right mid foot, or left or right heel. A movement detector (like VZ4000) detects any movements of user's limb immediately, so that the movement detecting module is allowed to analyze these movements and define them as a movement characteristic data for saving as a record or sending back to the control module to operate gait activity learning.
