Description

Technical Field

[0001] This invention relates to the medical field, and more particularly to a method of using a BFRT device for rehabilitation combined with a visual feedback device. Background Technology

[0002] Gait dysfunction is a common sequela of stroke patients. Data shows that over 50% of stroke patients suffer from residual limb dysfunction, and 30%-40% still experience balance and gait dysfunction three months after the stroke due to decreased muscle strength on the hemiplegic side. This decline in balance severely affects walking speed, stability, and gait, increasing the risk of falls, impacting patient safety, significantly reducing daily living abilities, and placing a greater economic burden on patients and their families. Motor rehabilitation and functional reconstruction play a crucial role in the rehabilitation process of stroke patients. However, improving balance and gait ability in stroke patients remains a key and challenging issue that urgently needs to be addressed in current rehabilitation treatment.

[0003] Therefore, this invention proposes a method for using a BFRT device for rehabilitation combined with a visual feedback device. Summary of the Invention

[0034] (2) Research method:

[0035] ①Patients with stroke who were admitted to the rehabilitation department and met the above criteria were selected. The purpose, method, possible benefits or risks of the study, and other relevant information were fully informed to the patients and their families. After the patients or their families signed the informed consent form, they were included in the study. Using Gpower3.1 software, setting the effect size as moderate level 0.5, statistical test power as 0.8, and significant level a as 0.05, the required sample size was calculated as 34. Considering the dropout rate of 10%-15%, 40 subjects who met the criteria were included, and were randomly divided into blood flow restriction training combined with balance training group (20 cases) and single balance training group (20 cases) according to the random number table method. The clinical data of gender, age, stroke type, disease duration, hemiplegia side, and lower extremity Brunnstrom stage of the two groups of patients were statistically analyzed, and the difference was not statistically significant (P>0.05).

[0036] ②Training method:

[0037] Both groups of patients were given corresponding drug symptomatic treatment during hospitalization, such as controlling blood pressure and blood sugar, and routine rehabilitation treatment based on nerve facilitation technology, including Bobath method, proprioceptive neuromuscular facilitation method, and motor learning therapy;

[0038] The control group received visual feedback balance training (Italian Tecnobody Company, model Prokin252) based on routine rehabilitation treatment: according to the patient's preference, the corresponding balance training games were selected, including table tennis game, balance ball game, skiing game, and fruit cutting game, 20 minutes / day, 5 days / week, for a total of 4 weeks of training;

[0039] The experimental group used blood flow restriction training in addition to the control group: while balancing training, the pressure blood flow restriction training belt (Henan Heju Rehabilitation Technology Co., Ltd., Theratools) was used, with pressure control at 160-200 mmHg. The pressure belt was worn on the proximal thigh of the affected side as close to the trunk as possible. After wearing, the inflation pump inflation tube was connected to the valve of the sleeve to facilitate pressure detection and control. To ensure the safety of training, the patient's blood pressure, oxygen saturation, and training belt pressure were monitored every 5 minutes during training, and the patient's subjective feelings (numbness, pain, fatigue) and limb circumference size, color change were constantly observed. The training time was consistent with the control group.

[0040] ③Rehabilitation evaluation index: all subjects received rehabilitation evaluation twice before and after treatment for 4 weeks during the trial. The evaluation indexes included:

[0041] Main evaluation index:

[0042] Balance test and training system assessment (Italian Tecnobody company, model Prokin252): the balance ability and stability limit of the patient were compared by obtaining the center of pressure related parameters (standard deviation in the forward and backward direction, standard deviation in the left and right direction, average movement speed in the forward and backward direction, average movement in the left and right direction, movement trajectory length and movement ellipse area) to evaluate the fall risk of the patient (the range of standing position stability limit is the dynamic balance range, and the patient will lose balance and fall out of the range; the smaller the range that can be reached, the easier the fall occurs);

[0043] Gait analysis: three-dimensional gait analysis and training system (model: GaitWatch) produced by Chongqing Hengshuo Medical Instrument Co., Ltd. was used for evaluation, and the walking ability of the patient was analyzed by analyzing the step frequency and joint activity during walking of the patient;

[0044] Secondary evaluation index:

[0045] Fugl-Meyer assessment scale lower extremity part (FMA-LE) was used to evaluate the lower extremity function of stroke patients;

[0046] Berg assessment: the balance function of the patient was evaluated;

[0047] Time up and go test (TUGT): the functional walking speed of the patient was evaluated, and the shorter the time, the faster the walking speed;

[0048] Activities of daily living assessment: the activities of daily living of the patient were evaluated by modified Barthel index (MBI);

[0049] Blood test: the risk of thrombosis was observed by D-dimer, and the higher the concentration of D-dimer, the higher the possibility of stable thrombosis. When the concentration of D-dimer is less than 0.5 mg / ml, it can help to exclude the risk of deep venous thrombosis.

[0050] Venous vascular ultrasound examination: whether the patient has thrombosis in the affected lower extremity was observed.

[0051] 4. Statistical analysis: SPSS 26.0 was used for statistical processing of the above evaluation indexes.

[0052] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
