Observation of the Efficacy of Millimeter Waves in the Treatment of Bronchitis

Bronchitis is a common and frequently occurring respiratory disease. While drug therapy remains the primary clinical treatment, there have been no reported studies in China to date on the use of millimeter-wave therapy for bronchitis. 1. Subjects and Methods 1.1 Subjects Treatment Group: Thirty patients with bronchitis were enrolled, including 14 males and 16 females, aged 3–65 years, with an average age of 26.1 years. The shortest duration of illness prior to irradiation was 1 week, while the longest lasted up to 1 year. During the irradiation period, all patients discontinued pharmacological treatment. Control Group: Thirty bronchitis patients were randomly selected from discharged medical records, comprising 22 males and 8 females, aged 1–69 years, with an average age of 35 years. The shortest duration of illness before hospitalization was 5 days, while the longest extended to 2.5 months. 1.2 Treatment Methods In the treatment group, a millimeter-wave therapeutic device was used, with an output power of 60 mW and a power density of less than 3 mW/cm². For each patient, the irradiation area was centered on the acupuncture points along the trunk; commonly selected acupoints included “Tiantu,” “Dazhui,” “Feiyu,” and “Dingchuan.” For preschool children, the total irradiation time for all selected acupoints over the initial 3 days was 10 minutes; thereafter, the duration could be adjusted according to individual circumstances, with the “Dazhui” or “Tiantu” acupoints appropriately extended by 5–10 minutes. For other patients, the total irradiation time for all acupoints ranged from 20 to 80 minutes, depending on the specific case, with each course of treatment lasting 5–10 days. Patients could be positioned either supine or seated, with the skin surface directly beneath the radiation head maintained within 1 cm. In the control group, patients received antibiotic therapy—either as monotherapy or in combination—with some also taking oral traditional Chinese medicine formulations, while remaining on bed rest. 2. Results The comparison of cure rates between the two groups is presented in Table 1. Chi-square analysis revealed no statistically significant difference (p > 0.05). Since millimeter-wave therapy is administered in courses lasting 5–10 days, and given the varying age ranges of the patients receiving treatment, the results were analyzed separately by age group. When assessing efficacy within 5 days, among preschool children, 5 cases (80%) responded to treatment in the treatment group, compared to 3 cases (33%) in the control group (t-test, p < 0.05). Among adolescents, 4 cases (75%) showed improvement in the treatment group, versus 3 cases (50%) in the control group (t-test, p > 0.05). In the adolescent group, 4 cases (75%) improved in the treatment group, while 6 cases (30%) showed improvement in the control group (t-test, p > 0.05). Among adults, 17 cases (70%) responded to treatment in the treatment group, compared to 18 cases (16.6%) in the control group (t-test, p < 0.01). A statistically significant difference was observed between the preschool and adult groups, whereas no significant difference was found between the adolescent and teenage groups. 3. Discussion Millimeter waves exert a series of biological effects when applied to the human body. From an electrical perspective, the acoustic-electric waves generated at the cell membrane produce effects similar to those induced by ultrasound. As the human body is a highly integrated functional system, millimeter-wave exposure can trigger local direct effects, visceral effects, and indirect effects. This therapeutic approach involves irradiating acupuncture point areas, allowing the body to receive the specific effects of millimeter waves through superficial acupoints, thereby achieving the effects of expectoration, cough suppression, and qi regulation. Damaged organs and tissues can undergo repair and regeneration. Moreover, unlike high‑energy radiation, millimeter-wave therapy does not cause even the slightest harm to the human body when administered in low doses.

Comprehensive Treatment of Bronchial Asthma with Millimeter Waves: 40 Cases

A total of 40 patients with bronchial asthma were enrolled, including 28 males and 12 females, aged 16–60 years, with disease durations ranging from 3 months to 30 years. All patients had moderate bronchial asthma. The patients were randomly divided into a treatment group of 40 cases, which received intravenous infusions of licomycin, aminophylline, and hydrocortisone, or oral prednisone, along with spiramycin, penicillin, or intravenous fluid replacement. Simultaneously, a millimeter-wave therapy device was used, with the radiation head placed over acupuncture points, primarily targeting Zhongwan, Feiyu, Chize, Lieque, Fengmen, Hegu, Fenglong, Tiantu, and Dingchuan. Each session involved 3–5 acupoints, with each point treated for 5–10 minutes, once daily for a total of 12 sessions per course of treatment. A control group of 40 patients was also established, receiving only the aforementioned medications without additional interventions. After treatment, the results showed that in both groups: Clinical control was achieved in 21 patients in the treatment group and 12 patients in the control group, characterized by complete relief of asthma symptoms, occasional mild exacerbations that resolved without medication, an increase in forced expiratory volume in one second (FEV1) or peak expiratory flow (PEF) of >35%, or FEV1/PEF values reaching ≥80% of the predicted normal range, with a PEF diurnal variability of <20%. In the treatment group, 16 patients exhibited marked improvement—asthma attacks were significantly reduced compared to baseline, with FEV1 and PEF increasing by 25%–35%, or FEV1/PEF reaching 60%–79% of the predicted value, while still requiring glucocorticoids or bronchodilators; in the control group, 20 patients showed marked improvement. In the treatment group, 3 patients experienced some improvement—asthma attacks were somewhat alleviated, with FEV1 or PEF increasing by 15%–20%, though they still required glucocorticoids or bronchodilators; in the control group, 7 patients showed some improvement. No improvement was observed in 1 patient in the control group. The clinical control rate was 52.5% in the treatment group versus 30% in the control group, with χ² = 4.18 and P < 0.05, indicating that the treatment group performed significantly better than the control group. Comparison of the rates of marked improvement, improvement, and no improvement between the two groups revealed no statistically significant differences (χ² test). From a modern perspective, asthma treatment must address two key aspects: eliminating bronchospasm and reducing nonspecific airway inflammation in order to effectively control asthma exacerbations. By combining conventional hormone and antibiotic therapies with high‑density millimeter‑wave treatment, and employing a meridian‑directed transmission approach, excellent therapeutic outcomes can be achieved. Millimeter‑wave irradiation induces immune modulation within the body while simultaneously stimulating neutrophils, enhancing their phagocytic capacity and exerting anti‑inflammatory effects. Due to the rich blood supply in the lungs, changes in immune components within the bloodstream can rapidly influence inflammatory processes within the alveoli.

Research on Millimeter-Wave Therapy for Peptic Ulcers and Its Mechanisms

Abstract – Objective: To explore the mechanisms underlying millimeter-wave therapy for peptic ulcers and its clinical value. Methods: A randomized, double-blind study was conducted on 22 patients with peptic ulcers treated with millimeter waves, during which gastric pH over 24 hours, basal acid output (BAO), maximal acid output (MAO), and gastric electrical activity rhythms were monitored before and after treatment. Results: The ulcer healing rate in the millimeter-wave group differed significantly from that of the control group. There were no statistically significant differences between the two groups in terms of total time (%) with pH < 4 before and after treatment, time (%) with pH < 4 in the upright and supine positions, BAO, or MAO (P > 0.05). However, the time (%) with pH > 5.6 in the supine position showed a significant difference between the two groups following treatment (P < 0.05). <o.01)。2周治疗后毫米波组中高、低主频患者恢复正常；异常m波消失；频谱恢复到正态分布；胃体部峰值幅度异常增高者，降到正常。结论：毫米波治疗可促进溃疡的愈合而不抑制生理性胃酸分泌，有助于胃、十二指肠运动恢复正常生理节律，有助于加强幽门括约肌防止十二指肠～胃反流的功能，且可使胃生物电活动和胃一肠运动功能得到改善。 1.1对象="" 1.2辐射装置及治疗方法="" 1.3指标(1)24h="" 1对象与方法="" mkiii型ph记录仪，将ph7.01和1.07标准缓冲液校准后的ph电极经鼻插入，以ph梯度法或x线透视定位于食管下括约肌下10cm处，连接携带式ph计录仪进行胃内24h="" ph的监测：采用瑞典ctd—synectics公司的单晶体锑电极连接digitrapper="" ph连续监测，所获资料输入装有ph分析系统的微型计算机分析、处理。分别计算ph<4总时间百分率，直立位和卧位ph<4时间百分率，卧位ph="" ulcer，十二指肠溃疡)4例，gu(gastric="" ulcer，胃溃疡)8例，溃疡直径1～2era，所有患者均除外nsaid溃疡、多发性和复合性溃疡，及心、肝、肺、胆、胰等脏器疾患。22例停药1周后进入研究，随机分成治疗和对照组，二组患者的性别、年龄、病情无显著差异。="" 为此，我们对22例患者进行随机、双盲、对照的毫米波治疗消化性溃疡临床研究，并观察治疗前后患者胃内24hph、基础胃酸(bao)、最大胃酸(mao)和胃电活动节律，现报告如下。="" 关键词="" 毫米波作为新的医用物理因子，已被用于消化性溃疡的治疗，溃疡的愈合率与西米替丁相近，且复发率较低[1]。但这些研究或联合使用了抗溃疡药物，或无严格的对照，特别对毫米波促进溃疡愈合机理缺乏客观的有针对性的研究。="" 毫米波；消化性溃疡；机理="" 治疗组使用的1号毫米波治疗仪，频率31.9ghz，输出功率60～100mw，功率密度8mw／cm2。对照组使用结构、开关、色泽及指示信号完全一致而无辐射输出的2号毫米波治疗仪，行双盲对照研究。治疗时患者平卧，仪器预热15min，探头置于中脘处，紧贴皮肤，辐射治疗30min，每天2次，间隔6h,2周为1疗程,治疗中患者禁烟、酒、酸性和刺激性食物。="" 男性患者22例；平均年龄30.4岁(19～55岁)。经临床及胃镜检查确诊为消化性溃疡活动期，其中du(duodenal=""> 5.6 Time Percentage. (2) Gastric Electrophysiological Analysis: Using the WCI-F4B Gastrointestinal Electrospectrum Analyzer, a fasting surface gastric electrogastrogram (EGG) was recorded prior to intragastric pH monitoring. Electrodes were placed at the corresponding surface locations of the gastric body and antrum as determined by B‑ultrasound. The EGG was continuously recorded for 6 minutes and 40 seconds, yielding scan graphs and various parameters analyzed via Fourier spectral analysis, including peak frequency (Fp), mean amplitude (Ap), zero-crossing frequency (Fz), and center frequency (Fc). (3) BAO and MAO Measurements: After a 12-hour fast, a gastric tube was inserted, and all fasting gastric fluid was aspirated and discarded. Subsequently, gastric fluid was continuously collected over 1 hour using an electric negative pressure of 4.0 kPa (30 mmHg) for BAO determination. Following this, pentagastrin (6 µg/kg) was administered subcutaneously, and gastric fluid samples were again collected under negative pressure at 15-minute intervals, for a total of four collections, to determine MAO. The BAO and MAO values were calculated as follows: BAO = (gastric fluid volume in mL × 0.1 mol/L NaOH required to titrate 5 mL of gastric fluid in mL) × 20/1000 = mmol/L; MAO = (gastric fluid volume in mL × 0.1 mol/L NaOH required to titrate 5 mL of gastric fluid in mL) × 20/1000 = mmol/L. 1.4 Efficacy Assessment: Two weeks after millimeter wave treatment, 24-hour intragastric pH, BAO, MAO, and gastric electrogastrograms were reevaluated to assess the impact of millimeter wave therapy on these parameters. A follow-up gastroscopy was performed to evaluate treatment outcomes. Efficacy criteria were defined as follows: (1) Cured—ulcer healing; (2) Effective—ulcer surface reduction of >50%; (3) Ineffective—ulcer surface reduction of <50%. 2 Results 2.1 Gastroscopic Follow-Up: Comparison of ulcer healing rates between the millimeter wave group and the control group revealed a highly significant difference between the two groups. 2.2 Effects of Millimeter Waves on 24-Hour Intragastric pH: Before and after millimeter wave treatment, there were no significant differences between the two groups in terms of the total percentage of time with pH < 4, nor in the percentage of time with pH < 4 in the upright or supine positions (P > 0.05). However, a significant difference was observed in the percentage of time with pH > 5.6 in the supine position (P < 0.01). These findings suggest that millimeter waves can promote normal peristalsis in the stomach and duodenum, thereby alleviating duodenogastric reflux. 2.3 There were no significant differences in BAO or MAO levels between the two groups before and after millimeter wave treatment, indicating that millimeter wave therapy does not affect gastric acid secretion. 2.4 Millimeter wave therapy had a more pronounced effect on gastric electrical rhythm activity: After 2 weeks of treatment, 4 out of 5 patients in the millimeter wave group who initially exhibited high dominant frequencies (Fp > 3.8 cpm) saw their dominant frequencies return to normal (Fp 2.8–3.5 cpm); 2 out of 3 patients with low dominant frequencies (Fp < 2.6 cpm) also experienced normalization of their dominant frequencies (Fp 2.8–3.5 cpm). Among patients who had previously displayed abnormal M waves, 3 out of 4 saw their M waves disappear following treatment. For 6 out of 8 patients whose dominant frequencies had shifted to the left or whose rhythms were irregular, post‑treatment spectral analysis showed that their rhythms returned to a normal distribution, with improved rhythmic stability. Among the 2 out of 4 patients whose average peak amplitudes in the gastric body were abnormally elevated (Ap > 300 µV), post‑treatment peak amplitudes normalized. 3 Discussion 3.1 In recent years, the biological effects of millimeter waves beyond their thermal properties have garnered considerable interest. Numerous studies have demonstrated the efficacy of millimeter wave therapy in treating peptic ulcers [1–3]. This study employed a randomized, double‑blind, controlled trial design and confirmed that, after 2 weeks of millimeter wave treatment, the ulcer healing rate reached 64%, with a highly significant difference compared to the control group. This indicates that, when other factors influencing ulcer healing are excluded, millimeter wave therapy is indeed effective in treating peptic ulcers—and its 2‑week cure rate is comparable to that achieved with H2 receptor antagonists. 3.2 Ulcer formation is closely linked to the weakening of gastric mucosal protective factors and the enhancement of damaging factors; as the adage goes, “No acid, no ulcer.” Therefore, inhibiting acid secretion remains one of the most important and effective strategies in current pharmacological treatments for ulcers and in promoting ulcer healing. To gain a deeper understanding of the precise mechanisms underlying millimeter wave therapy for ulcers, we conducted pre‑ and post‑treatment 24‑hour intragastric pH monitoring and analyzed gastric acid secretory function (BAO and MAO) in both treatment groups. The results showed that millimeter wave therapy did not significantly affect gastric acid secretion, confirming that millimeter waves promote ulcer healing without suppressing gastric acid production. Gastric acid is a crucial digestive mediator in the body’s normal digestive processes; prolonged and intense acid suppression can lead to abnormal increases in gastrin levels, which, as demonstrated in animal models, can induce gastric metaplasia [4] and carcinoid tumors [5]. In contrast, millimeter wave therapy for ulcers operates through non‑acid‑suppressing mechanisms. This represents a fundamental distinction from the widely used, highly acid‑suppressive medications currently employed in the treatment of peptic ulcers—a distinction that is particularly advantageous for the treatment of senile, non‑hyperacidity ulcers. 3.3 Our 24‑hour intragastric pH monitoring revealed that millimeter wave therapy exerted a marked effect on duodenogastric reflux caused by varying degrees of gastroduodenal dysmotility commonly observed in patients with peptic ulcers. In the treatment group, the percentage of time with intragastric pH > 5.6 in the supine position decreased from 34.3 ± 19.3 to 5.4 ± 7.3 (P < 0.01). This suggests that millimeter wave therapy helps restore normal physiological rhythms in gastroduodenal motility and enhances the function of the pyloric sphincter in preventing duodenogastric reflux. Studies have shown that bile acids, pancreatic enzymes, and the hemolytic lecithins produced within duodenal contents are potent gastric mucosal damaging agents—not only can they deepen ulcer lesions and lead to refractory ulcers, but they can also cause inflammation, erosion, and edema of the normal gastric mucosa, ultimately triggering new ulcers [6]. By regulating gastroduodenal function and inhibiting pathological duodenogastric reflux, millimeter wave therapy blocks the destructive effects of harmful duodenal substances on the gastric mucosa, thereby playing a significant role in promoting the healing of peptic ulcers. 3.4 Gastric electrical activity forms the foundation of gastrointestinal motility; it is closely tied to smooth muscle cell metabolism and is regulated by neural and humoral factors. Research has confirmed that EGG can reflect the interdigestive motor complex (IDMEC) in the fasting state [7, 8], while the dominant frequency (Fp) in gastric electrospectral analysis accurately reflects gastric rhythm, and amplitude (Ap) is associated with gastric contractions [9, 10]. Our findings indicate that among patients with peptic ulcers, a substantial proportion exhibit slow or rapid gastric motility, as well as irregularities in gastric electrical rhythm. After millimeter wave treatment, most of these abnormalities were restored to normal ranges, demonstrating that millimeter waves can improve gastric bioelectrical activity and gastrointestinal motility by modulating the metabolism of gastric mucosal and smooth muscle cells. In patients with peptic ulcers—particularly those with duodenal ulcers—abnormal M wave patterns may appear on EGG. After 2 weeks of treatment, all M waves disappeared, and ulcers healed, further confirming the reliable therapeutic efficacy of millimeter waves in treating peptic ulcers. Millimeter wave therapy has opened up a new approach to the treatment of peptic ulcers—simple, cost‑effective, and highly effective. It primarily works by regulating the metabolism of gastric mucosal and smooth muscle cells, restoring normal bioelectrical activity in the stomach, coordinating gastrointestinal motility more effectively, enhancing gastric mucosal protective factors, and attenuating the effects of damaging factors—ultimately achieving therapeutic outcomes. However, further research is needed to explore the effects of millimeter waves on gastrointestinal hormones, gastric mucosal blood flow, and Helicobacter pylori—the bacterium implicated in the pathogenesis of peptic ulcers.

50 Cases of Peptic Ulcer Treated with Millimeter Wave Therapy

Subject Terms: Peptic Ulcer / Treatment; Physical Therapy; Cimetidine / Therapeutic Applications l. Subjects and Methods 1.1 Subjects: A total of 80 patients were diagnosed with peptic ulcers via endoscopy or upper gastrointestinal barium meal radiography. Among them, 22 had gastric ulcers (GU), 48 had duodenal bulb ulcers (Du), and 10 had complex ulcers (CU). There were 52 males and 28 females, aged 23–59 years, with an average age of 45 years. The duration of illness ranged from 20 days to 20 years. 1.2 Methods: The patients were randomly divided into three groups: Group A consisted of 30 patients treated with millimeter wave therapy combined with cimetidine (Cim), at a dose of 0.6–0.8 g/day, administered in divided oral doses, with one treatment course lasting 20 days; Group B comprised 30 patients receiving cimetidine alone, using the same dosage and treatment duration as Group A; and Group C included 20 patients receiving millimeter wave therapy alone. During millimeter wave treatment, patients were placed in the supine position with the upper abdomen exposed. The radiation head of the millimeter wave therapy device was positioned over the surface projection of the ulcer, with a distance of ≤1 cm from the skin. The output frequency was 38 GHz, with an output power ranging from 60 mW to 140 mW, administered once daily for 30 minutes per session, with each treatment course lasting 20 days. During treatment, most patients reported no sensation whatsoever, while a few experienced a mild vibrating sensation in the abdominal region. At the end of each treatment course, all patients underwent follow-up endoscopic examination or upper gastrointestinal barium meal radiography. Blood, urine, and stool routine tests, as well as liver and kidney function assessments, were conducted both before and after treatment in Group C. 2. Results 2.1 Efficacy Assessment: Cure: ① Disappearance of ulcer symptoms; ② Complete resolution of ulcers on endoscopy or X‑ray examination. Effective: ① Significant reduction or near‑complete disappearance of ulcer symptoms; ② Marked reduction in ulcer size, with the ulcer area shrinking to more than half its original size. Ineffective: ① No change in symptoms; ② No improvement in ulcer appearance on endoscopy or X‑ray examination, or even enlargement of the ulcer. 2.2 Treatment Outcomes: After millimeter wave therapy, abdominal pain began to subside within 3–5 days in Groups A and C, accompanied by improved appetite (Table 1). In the first treatment course, 25 out of 30 patients in Group A and 14 out of 20 in Group C achieved cure, whereas only 2 out of 30 patients in Group B showed improvement. Comparing Groups A and C with Group B, the therapeutic efficacy was significantly superior in the former two groups. By the second treatment course, both Groups A and C had achieved complete cure, while Group B still had 26 cured patients out of 30. These results clearly demonstrate that millimeter wave therapy is more effective than cimetidine, with a markedly shorter treatment duration required for healing. 3. Discussion In recent years, physical therapies for peptic ulcers have gradually gained increasing attention. The mechanism underlying millimeter wave treatment of peptic ulcers involves the generation of substantial energy within gastric tissue through resonant effects following exposure to the body, thereby improving local tissue perfusion, enhancing nutrient supply and metabolic activity in tissue cells, boosting regenerative capacity, and accelerating ulcer healing. Currently, H₂ receptor antagonists are widely used both domestically and internationally for the treatment of peptic ulcers, with cimetidine being the most commonly prescribed medication. However, long‑term use of cimetidine is associated with certain side effects. The results of this study indicate that millimeter wave therapy exhibits faster onset of action and superior therapeutic efficacy compared to cimetidine. Moreover, millimeter wave therapy is non‑invasive, causes no discomfort or adverse reactions, and is highly acceptable to patients.

Clinical Observation on the Treatment of 154 Cases of Bi Syndrome with Millimeter Wave Therapy

Abstract: We treated 154 patients with bi syndrome using millimeter-wave therapy. The results indicate that millimeter waves demonstrate significant therapeutic efficacy across various types of bi syndrome, including pain‑bi, fixed‑bi, moving‑bi, and heat‑bi, with an overall effective rate of 98.7% and a mean treatment duration of just 10.68 days. Bi syndrome is a common and frequently occurring condition in traditional Chinese medicine clinical practice. Over the past two years, our hospital has conducted clinical observations on bi syndrome using localized irradiation with a millimeter‑wave therapy device, achieving favorable clinical outcomes. The findings are summarized as follows. Case Selection: All 154 cases were selected from the outpatient clinic of the TCM department. After differential diagnosis and syndrome typing, patients received millimeter‑wave therapy and were subjected to clinical follow‑up. The inclusion criteria for these cases adhered to the diagnostic standards outlined in the “Clinical Diagnostic Criteria and Standards for Cure and Improvement” compiled by the Health Department of the General Logistics Department of the People’s Liberation Army. Some patients also underwent X‑ray and CT imaging. The general characteristics of the patients included 57 males and 97 females, ranging in age from 7 to 80 years, with an average age of 51.56 years. Among them, 53 cases had a disease course of less than 30 days; 72 cases had a disease course between 30 days and 1 year; and 29 cases had a disease course exceeding 1 year. According to TCM differential diagnosis and syndrome typing, 142 cases were classified as wind‑cold‑damp bi (including 1 case of moving bi, 121 cases of pain bi, and 20 cases of fixed bi), while 12 cases were diagnosed as heat bi. Of the 154 cases in this group, 24 were accompanied by periarthritis of the shoulder, 2 had tennis elbow, 4 had soft tissue injuries, 4 had lumbago and leg pain, 62 exhibited osteophytic changes, 1 had spinal stenosis, 2 had sciatica, 1 had cerebral infarction, 5 had fractures, and 1 had an infection. Treatment Method: Millimeter‑wave therapy was administered using a millimeter‑wave therapy device (wavelength 8 mm), with local, close‑contact irradiation once daily for 20 minutes per session, with a treatment course lasting 10 days. Efficacy Assessment: Efficacy was evaluated according to the three-tiered criteria—cure, improvement, and no effect—as defined in the “Clinical Diagnostic Criteria and Standards for Cure and Improvement” compiled by the Health Department of the General Logistics Department of the People’s Liberation Army. Results: Among the 154 cases in this group, 97 were cured, 55 showed improvement, and 2 were deemed ineffective. The average time to cure was 10.68 days. The cure rate was 62.99%, the improvement rate was 35.71%, and the overall effective rate reached 98.70%, as shown in Tables 1, 2, and 3. Typical Cases Case 1: Cha XX, female, 49 years old. She reported recurrent episodes of low back pain since 1987, with severe pain in May 1992 that prevented her from turning over in bed. A lumbar spine X‑ray, taken at the local community hospital, revealed a lumbar disc herniation. The diagnosis was lumbar disc herniation. On October 12, 1993, when she presented to our hospital, she experienced intense low back pain, was unable to stand upright, and had limited range of motion. The straight‑leg raise test was positive, and localized tenderness was prominent. Following millimeter‑wave therapy, her pain significantly subsided after just three days. Most of the pain was relieved, and her restricted mobility improved markedly. After 10 treatment sessions, her pain had completely disappeared, and she could move freely without limitation—clinically cured. Case 2: Wang XX, male, 69 years old. He had experienced left knee pain for 2 months, accompanied by a tumor approximately the size of a ping‑pong ball on the lateral aspect of his knee, making walking extremely difficult. On December 29, 1993, he underwent millimeter‑wave therapy; four days later, his pain had noticeably alleviated. By day 7, the swelling had resolved, the pain was gone, and his knee function had largely returned to normal. He discontinued treatment on his own, and no recurrence was observed within one month. Discussion 1. The efficacy of low‑power millimeter‑wave local irradiation in treating various types of bi syndrome is clear, with particularly notable effects on pain‑bi and fixed‑bi. Millimeter wave therapy demonstrates a marked impact on symptoms such as pain, swelling, and restricted joint movement. Data from this study show a cure rate of 62.97% for bi syndrome, with an average treatment duration of 10.68 days, highlighting the advantages of millimeter‑wave therapy for bi syndrome: good therapeutic efficacy and a short treatment course. 2. The data from this study indicate that the cure rate for numbness associated with bi syndrome was 21.62%, with a marked response rate of 45.95%, an effective rate of 18.92%, and a no‑effect rate of 13.51%. While these results are not entirely ideal, they may be related to the relatively short treatment duration—and further observation is needed to fully assess the long‑term efficacy of millimeter‑wave therapy for this symptom.
