Description

Technical Field

[0001] The present invention relates to the technical field of binaural integration of cochlear implant recipients, and in particular to a method for measuring binaural interaction components of bilateral cochlear implant recipients. Background Art

[0002] With the continuous advancement and rapid development of science and technology, the medical field has ushered in unprecedented innovations, especially in hearing rehabilitation technology. Today, more and more patients with severe or even profound sensorineural hearing loss are able to benefit from the advanced treatment of bilateral cochlear implant technology. This breakthrough has greatly improved their quality of life and social skills. In these cochlear implant surgeries, electrically evoked auditory brainstem response (EABR) is a highly accurate and critical electrophysiological test method that is widely used in the preoperative evaluation of patients and postoperative effect monitoring. EABR can not only help doctors accurately judge the functional status of the patient's auditory pathway, but also provide a scientific basis for the formulation of surgical plans, thereby ensuring the maximization of the implant effect.

[0003] For patients who have received bilateral cochlear implants, BIC can be used as an important indicator to assess their binaural integration ability. BIC refers to the phenomenon that in the binaural hearing system, the sound signals received by the two ears can be effectively integrated at the brainstem level. This process is crucial to restoring and improving the patient's spatial positioning ability, speech recognition rate and overall auditory experience. By evaluating BIC through special testing methods, doctors can gain an in-depth understanding of whether the patient's binaural integration mechanism is sound, and then provide personalized guidance for subsequent rehabilitation training.

[0004] However, it is worth noting that although bilateral cochlear implant technology and its evaluation system have become increasingly mature, there is still an obvious blank area in China: there is no method to directly reflect and quantify binaural integration ability using specific stimulation patterns. This means that further scientific exploration and technological innovation are needed to accurately measure and optimize the binaural auditory synergy of patients. In the future, with in-depth research in fields such as neuroscience and biomedical engineering, we have reason to believe that more accurate and efficient evaluation methods will emerge to comprehensively evaluate the binaural integration ability of bilateral cochlear implant recipients, ultimately bringing them a more natural and efficient hearing experience.

[0005] Existing simultaneous bilateral electrically evoked auditory brainstem responses are mostly obtained by modified speech processors or modified detection equipment. There is no clear measurement method in China. Summary of the invention

[0006] The purpose of the present invention is to address the deficiencies in the prior art. To achieve the above purpose, a method for measuring binaural interaction components of bilateral cochlear implant recipients is used to solve the problems raised in the above background technology.

[0007] A method for measuring binaural interaction components of a bilateral cochlear implant recipient comprises the following steps:

[0008] Step S1, prepare and measure monaural EABR: the subject sits quietly and waits, and uses specific equipment and electrodes to measure and record the EABR waveforms of two monaural ears in sequence;

[0009] Step S2, prepare equipment and connections for bilateral simultaneous EABR measurement: after the left ear measurement in step S1 is completed, prepare another computer and detection coil for bilateral simultaneous EABR measurement;

[0010] Step S3, bilateral simultaneous EABR measurement: after simultaneously giving electrical stimulation to both cochlear implants, recording the EABR waveform under the current stimulation mode;

[0011] Step S4, according to the EABR waveform data recorded in steps S1 to S3, calculate the BIC value according to the EABR waveform formula, and output the calculation result.

[0012] As a further solution of the present invention: the specific steps in step S1 include:

[0013] Step S11, subject preparation: the subject needs to sit quietly and comfortably on a reclining chair and remain relaxed so as to perform accurate measurement;

[0014] Step S12, electrode and coil placement: using professional electrode and coil equipment, the positive stimulation electrode is connected to the subject's detection coil through a programming interface and audio processing software; the detection coil is attached to the scalp surface where the suction of the cochlear implant is the strongest in the measuring ear to ensure that the response caused by the electrical stimulation can be accurately captured;

[0015] Step S13, recording electrode placement: placing the recording electrode, the ground electrode and the reference electrode in the middle of the forehead, the middle of the eyebrows and in front of the tragus of the test ear, respectively, to record the EABR waveform;

[0016] Step S14, measuring and recording: first measuring the EABR waveform of the right ear and recording it as R; then measuring the EABR waveform of the left ear and recording it as L.

[0017] As a further solution of the present invention: the specific steps in step S2 include:

[0018] Step S21, device connection: after completing the single-ear EABR measurement, it is necessary to prepare another computer to connect to the programming interface in order to perform bilateral simultaneous EABR measurement;

[0019] Step S22, repositioning the coil: remove the detection coil from the measured ear and reattach it to the scalp surface of the other ear where the cochlear implant has the strongest suction force, in preparation for simultaneous bilateral measurement.

[0020] As a further solution of the present invention: the specific steps in step S3 include:

[0021] Step S31, providing electrical stimulation: providing electrical stimulation simultaneously through the detection coils connected to the cochlear implants on both sides to simulate the sound input in the bilateral hearing environment;

[0022] Step S32, waveform recording: Use an EABR recorder to record the bilateral simultaneous EABR waveform generated in the current stimulation mode, and record it as B.

[0023] As a further solution of the present invention: the specific steps in step S4 include:

[0024] The three waveform data of EABR waveform R, L and B recorded previously are sorted out, and then the BIC value is calculated according to the EABR waveform formula. The formula is:

[0025] BIC = B - (L + R).

[0026] Compared with the prior art, the present invention has the following technical effects:

[0027] By adopting the above technical scheme, we can deeply reflect the binaural integration state of bilateral cochlear implant recipients through the stimulation mode based on the electrically evoked auditory brainstem response (EABR). This method precisely controls and applies specific electrical stimulation signals to the bilateral cochlear implants, and then observes and analyzes the auditory brainstem response induced thereby, thereby capturing the collaborative work of the two ears in processing sound information. On this basis, the binaural interaction component (BIC) can be accurately calculated by further using advanced signal processing technology. This indicator is an important parameter for measuring the binaural integration ability of bilateral cochlear implant recipients. The calculation of BIC not only takes into account the intensity and speed of the response of the unilateral cochlea to the stimulus, but also deeply explores the mutual coordination and influence of the two cochleae when receiving and processing the same or different sound signals, effectively revealing how bilateral cochlear implant recipients use binaural cues in a complex auditory environment to enhance the accuracy of sound localization, improve the clarity of speech understanding, and optimize the overall auditory experience. Therefore, the method of calculating BIC based on the EABR stimulation mode provides a scientific, objective and effective means for evaluating and optimizing the binaural integration ability of bilateral cochlear implant recipients.

[0033] Please refer to Figure 1 In an embodiment of the present invention, a method for measuring binaural interaction components of a bilateral cochlear implant recipient includes:

[0034] Step S1, prepare and measure the monaural EABR: the subject sits quietly and waits, and uses specific equipment and electrodes to measure and record the EABR waveforms of the two ears in sequence. The specific steps include:

[0035] Step S11, subject preparation: the subject needs to sit quietly and comfortably on a reclining chair and remain relaxed so as to perform accurate measurement;

[0036] Specifically, a qualified subject was selected and asked to sit quietly and comfortably on a professional medical recliner. To ensure the accuracy of the measurement, we instructed the subject to stay relaxed and avoid any head movement or body tension that may affect the measurement results.

[0037] Step S12, electrode and coil placement: using professional electrode and coil equipment, the positive stimulation electrode is connected to the subject's detection coil through a programming interface and audio processing software; the detection coil is attached to the scalp surface where the suction of the cochlear implant is the strongest in the measuring ear to ensure that the response caused by the electrical stimulation can be accurately captured;

[0038] Specifically, we use professional electrodes and coil equipment to prepare for the measurement. The positive stimulation electrode is connected to the subject's cochlear implant through a programming interface (such as the MAX programming interface) and audio processing software (such as Maestro software). At the same time, we precisely attach the detection coil to the scalp surface of the subject's measurement ear where the cochlear implant has the strongest suction force to ensure that the auditory brainstem response caused by electrical stimulation can be accurately captured.

[0039] Step S13, recording electrode placement: placing the recording electrode, the ground electrode and the reference electrode in the middle of the forehead, the middle of the eyebrows and in front of the tragus of the test ear, respectively, to record the EABR waveform;

[0040] Specifically, the recording electrode, ground electrode, and reference electrode are placed in the middle of the forehead, the middle of the eyebrows, and 1 cm in front of the tragus of the test ear, respectively. The precise placement of these electrodes is crucial to obtaining clear and accurate EABR waveforms.

[0041] Step S14, measuring and recording: first measuring the EABR waveform of the right ear and recording it as R; then measuring the EABR waveform of the left ear and recording it as L.

[0042] Specifically, we start to measure EABR. First, we electrically stimulate the subject's right ear and use an EABR recorder to record the waveform generated, which is recorded as R. Then, we repeat the same steps to measure the subject's left ear and record the recorded waveform as L.

[0043] Step S2, prepare equipment and connections for bilateral simultaneous EABR measurement: After the left ear measurement in step S1 is completed, prepare another computer and detection coil for bilateral simultaneous EABR measurement. The specific steps include:

[0044] like Figure 2 As shown, the diagram is a flow chart for measuring bilateral simultaneous EABR;

[0045] Step S21, device connection: after completing the single-ear EABR measurement, it is necessary to prepare another computer to connect to the programming interface in order to perform bilateral simultaneous EABR measurement;

[0046] Step S22, repositioning the coil: remove the detection coil from the measured ear and reattach it to the scalp surface of the other ear where the cochlear implant has the strongest suction force, in preparation for simultaneous bilateral measurement.

[0047] Step S3, bilateral simultaneous EABR measurement: after simultaneously giving electrical stimulation to both cochlear implants, the EABR waveform under the current stimulation mode is recorded. The specific steps include:

[0048] Step S31, providing electrical stimulation: providing electrical stimulation simultaneously through the detection coils connected to the cochlear implants on both sides to simulate the sound input in the bilateral hearing environment;

[0049] Step S32, waveform recording: Use an EABR recorder to record the bilateral simultaneous EABR waveform generated in the current stimulation mode, and record it as B.

[0050] Step S4, according to the EABR waveform data recorded in steps S1 to S3, the BIC value is calculated according to the EABR waveform formula, and the calculation result is output. The specific steps include:

[0051] like Figure 3 As shown, the figure is a waveform diagram of a subject;

[0052] The three waveform data of EABR waveform R, L and B recorded previously are sorted out, and then the BIC value is calculated according to the EABR waveform formula. The formula is:

[0053] BIC = B - (L + R).
