When the treatment prescription sent by the intelligent mobile terminal 200 is an electrotherapy prescription, the wearable foot drop treatment host 100 starts a training mode, mainly uses low-frequency electrical stimulation to carry out training treatment, and has an output frequency range of 1-120HZ, a pulse width range of 50-500us, and an output intensity of 0-100mA or 0-100V (a test load of 500 ohms). Before the training mode is started, a user freely adjusts parameters such as frequency, pulse width, treatment time, pulse group modulation (including rise time, hold time, fall time, intermittence time and the like) and the like through the intelligent mobile terminal 200 to set an electrotherapy prescription for a specified patient, in the process, the current set parameters can be added and stored in a prescription list of the intelligent mobile terminal through one key, and the prescription can also be sent to the wearable foot drop treatment host 100 for storage, so that the electrotherapy prescription can be directly used for treatment next time, and the operation steps of adjusting the parameters again are simplified. After the wearable foot drop treatment host 100 receives the delivered electrotherapy prescription, a training mode is started to perform electrostimulation output treatment, the control module 101 generates and outputs a first control instruction according to the electrotherapy prescription to control the waveform output circuit 4 to output pulse current so as to perform electrostimulation treatment on a patient, and meanwhile, the control module 101 generates and outputs a second control instruction according to the electrotherapy prescription to control the output of the booster circuit 3 so as to modulate the signal amplitude of the pulse current. The electric stimulation treatment is carried out on the leg of the patient by executing the corresponding electrotherapy prescription parameters issued by the intelligent mobile terminal 200, so that the leg state of the patient can be improved.

Before the evaluation mode is started, the user sets parameters such as a shank flexion and extension angle threshold, a thigh abduction and adduction angle threshold, treatment duration and the like through the intelligent mobile terminal 200, and sets an evaluation prescription for a specified patient. Because patients are different in individuals, when some patients stand normally, the lower legs are not vertical to the ground, a certain initial angle exists, calibration operation needs to be carried out, the initial angle is recorded, and then the current change angle is calculated, so that before the evaluation prescription is set for different patients, the initial position of the six-axis sensor 2 needs to be calibrated, the current binding position is selected to be the left leg or the right leg, and then the patient user is asked to stand vertically and then the initial position of the sensor is calibrated.
The wearable foot drop treatment host 100 can enter an evaluation mode for use after receiving a sent evaluation prescription, the control module 101 calculates a current shank flexion and extension angle, a thigh abduction and adduction angle, a step number and displacement of a patient according to the motion state information acquired by the six-axis sensor 2, transmits the current shank flexion and extension angle, thigh abduction and adduction angle, step number and displacement of the patient and current treatment time to the display 7 and the intelligent mobile terminal 200, and the control module 101 controls the voice module 6 to output voice prompt information and controls the display 7 to display the prompt information when the current shank flexion and extension angle and thigh abduction and adduction angle of the patient exceed a preset range.
Specifically, after the control module 101 performs operations such as setting the sensitivity of the six-axis sensor 2 and initializing the pedometer through the SPI interface, the acceleration values of the six-axis sensor 2 in the original x, y, and z directions and the count value of the hardware pedometer can be read. The current shank flexion-extension angle and thigh abduction-adduction angle of the patient can be calculated by using the acceleration components of the x, y and z axes of the six-axis sensor 2; the calculation of the number of steps is obtained by directly reading the count value of the pedometer of the six-axis sensor 2. When calculating the displacement, the difference between walking and running is considered, the walking displacement and the running displacement are respectively calculated, and then the walking displacement and the running displacement are added to obtain the total displacement. If the time of each step exceeds 500ms, the walking mode is judged, the size of the displacement base number of each step is set to be 0.5m, if the time of each step does not exceed 500ms, the running mode is judged, the displacement base number of each step is set to be 0.65m, the total displacement number in the treatment process can be obtained by multiplying the step number by the displacement base number, and the accuracy of displacement calculation under different use conditions is achieved by distinguishing the walking mode from the running mode. After the calculation is completed, the control module 101 transmits the current shank flexion and extension angle, thigh abduction and adduction angle, step number, displacement and current treatment time of the patient to the display screen 7 and the intelligent mobile terminal 200 at the same time, and can display the current shank flexion and extension angle (-90 ° to 90 °), thigh abduction and adduction angle (-90 ° to 90 °), step number, displacement, current treatment time and the like on the display interface of the intelligent mobile terminal 200 and the display screen 7 in real time, when any one of the current shank flexion and extension angle and thigh abduction angle exceeds the range of-10 ° to 10 °, the corresponding angle display values on the intelligent mobile terminal 200 and the display screen 7 become yellow, and meanwhile, the intelligent mobile terminal 200 and the voice module 6 ring to prompt the patient to try to keep in the normal range, correct the gait of the user, and avoid the occurrence of an O-shaped leg or an X-shaped leg, the leg assessment and exercise of the patient are facilitated.
When the treatment prescription sent by the intelligent mobile terminal 200 is a walking treatment prescription, the wearable foot drop treatment host 100 starts a walking mode, and the walking treatment function is realized by recording the bending angles of the lower legs and the thighs of the patient during walking and triggering electrical stimulation treatment in combination with the angles. Before the walking mode is started, the user sets parameters such as a shank flexion and extension angle threshold, a thigh abduction and adduction angle threshold, treatment duration, an electrical stimulation triggering condition, electrical stimulation intensity and the like through the intelligent mobile terminal 200, and sets a walking treatment prescription for a specified patient. Since patients vary from patient to patient, the initial position of the six-axis sensor 2 needs to be calibrated and adjusted to determine an appropriate electrical stimulation intensity for the patient before setting up an evaluation prescription for different patients: the patient sits stably, the lower limbs are relaxed, the knees are slightly bent, the skin of the lower legs is exposed, and the skin is cleaned by using alcohol or soap water. ② the electrode plates are respectively arranged at the common peroneal nerve and the tibialis anterior muscle. After the wearable foot drop treatment host 100 is connected through the intelligent mobile terminal 200, the current binding position is selected to be the left leg or the right leg, then the electric stimulation intensity (for example, 20mA, mainly the output intensity which can be accepted by a user and can achieve the best stimulation effect) suitable for self stimulation is adjusted, the current binding position is selected to be the left leg or the right leg, and then the user is asked to stand upright and then the initial position of the sensor is calibrated.
The wearable foot drop treatment host 100 can enter a walking mode for use after receiving a walking treatment prescription issued, the control module 101 calculates a current shank flexion and extension angle, a thigh abduction and adduction angle, a shank pose, step numbers and displacement of a patient according to motion state information acquired by the six-axis sensor 2, transmits the current shank flexion and extension angle, the thigh abduction and adduction angle, the step numbers and the displacement of the patient and current treatment time to the display 7 and the intelligent mobile terminal 200, the control module 101 controls the voice module 6 to output voice prompt information and controls the display 7 to display the prompt information when the current shank flexion and extension angle and the thigh abduction and adduction angle of the patient exceed a preset range, the control module 101 controls the waveform output circuit 4 to output pulse current to perform electrical stimulation treatment on the patient when the current shank pose of the patient meets a first preset condition, and when the current shank pose of the patient meets a second preset condition, controlling the waveform output circuit 4 to stop outputting the pulse current.
Specifically, after the control module 101 performs operations such as setting the sensitivity of the six-axis sensor 2 and initializing the pedometer through the SPI interface, the acceleration values of the six-axis sensor 2 in the original x, y, and z directions and the count value of the hardware pedometer can be read. The current shank flexion-extension angle and thigh abduction-adduction angle of the patient can be calculated by using the acceleration components of the x, y and z axes of the six-axis sensor 2; the calculation of the number of steps is obtained by directly reading the count value of the pedometer of the six-axis sensor 2. When calculating the displacement, the difference between walking and running is considered, the walking displacement and the running displacement are respectively calculated, and then the walking displacement and the running displacement are added to obtain the total displacement. If the time of each step exceeds 500ms, the walking mode is judged, the size of the displacement base number of each step is set to be 0.5m, if the time of each step does not exceed 500ms, the running mode is judged, the displacement base number of each step is set to be 0.65m, the total displacement number in the treatment process can be obtained by multiplying the step number by the displacement base number, and the accuracy of displacement calculation under different use conditions is achieved by distinguishing the walking mode from the running mode. After the calculation is completed, the control module 101 transmits the current shank flexion and extension angle, the thigh abduction and adduction angle, the step number, the displacement and the current treatment time of the patient to the display 7 and the intelligent mobile terminal 200 at the same time, the current shank flexion and extension angle (-90 to 90 degrees), thigh abduction and adduction angle (-90 to 90 degrees), the number of steps, the displacement, the current treatment time and the like can be displayed in real time on the interface of the intelligent mobile terminal 200 and the display screen 7, when any one of the current shank flexion-extension angle and the thigh abduction-adduction angle exceeds the range of-10 degrees to 10 degrees, the corresponding angle display values on the smart mobile terminal 200 and the display screen 7 may become yellow, meanwhile, the intelligent mobile terminal 200 and the voice module 6 may ring to prompt the patient to try to keep in a normal range, correct the gait of the user, and avoid the occurrence of an O-leg or an X-leg. In addition, the walking mode also has the function of angle triggering electrical stimulation, when the situation that the lower leg reaches the highest point backwards (a first preset condition) is detected, the electrical stimulation is triggered, and when the forward angle of the lower leg exceeds 0 degree (a second preset condition), the electrical stimulation is stopped, so that the function of walking treatment by using low-frequency electrical stimulation is achieved. In some embodiments of the present invention, the output electrical stimulation is further limited to 1-3 seconds, so as to avoid the injury caused by insufficient stimulation or long stimulation when the patient moves too fast or too slow.
The invention can compare the data recorded by the evaluation mode and the walking mode (for example, the shank flexion and extension angle, the thigh abduction angle, the step number, the displacement and the like of the walking mode are obviously improved compared with the evaluation mode in the same treatment time), so that the treatment confidence of the user is improved, and the active participation of the user is improved.
