A bibliometria é uma excelente ferramenta que permite determinar as obras e autores mais citados, assuntos mais enfatizados, palavras-chave mais utilizadas, autores que mais publicaram, bem como suas respectivas áreas de formação, revelando, assim, parte da dinâmica de produção do conhecimento desse campo de pesquisas. O objetivo deste estudo foi realizar análise bibliométrica sobre a utilização do músculo fibular terceiro como retalho em cirurgia ortopédica. Para tal, realizou- se uma pesquisa bibliométrica, de caráter observacional e abordagem quantitativa, utilizando como palavras-chave as seguintes combinações booleanas ("fibularis tertius" OR "peroneus tertius" OR "fibularis anterior" AND "surgery" OR "Plastic surgery" OR "surgical flap" OR "Lower extremity" AND "human") através da plataforma SCOPUS. A análise bibliométrica encontrou 33 artigos publicados em periódicos de grande impacto em nível mundial, principalmente nos anos de 2018 e 2020. Ao associar as palavras-chave através da Lei de Bradford, lei esta que estima o grau de relevância de periódicos que atuam em áreas do conhecimento específicas, a revista mais relevante foi a Surgical And Radiologic Anatomy, seguida da Journal Of Foot And Ankle Surgery e Plastic And Reconstructive Surgery. O pesquisador Arnold et al., 1999, do Setor de Cirurgia Plástica e Reconstrutiva dos Estados Unidos, publicou o artigo intitulado "Muscle flaps in osteomyelitis of the lower extremity: A 20-year account", no periódico Plastic and Reconstructive Surgery, e obteve 61 citações e apresentou o maior fator H para a pesquisa realizada. As análises bibliométricas podem se configurar em uma metodologia tecnológica importante para a medicina, por revelar padrões de pesquisa e identificação de tendências, assim como podem também ser utilizadas em qualquer base de dados, sendo sugeridos novos estudos. O uso dos recursos disponíveis na base de dados SCOPUS se mostrou interessante para a realização de estudos desse tipo em curto espaço de tempo, além de propiciar a possibilidade de estudos posteriores com análise de outros indicadores, principalmente de um tema tão relevante para a cirurgia ortopédica.

The pre-season consisted of 11 weeks of training, divided into three stages: Stage 1, lasting 6 weeks; Stage 2, lasting 3 weeks; Stage 3, lasting 2 weeks. The internal training load was evaluated in all training sessions through the session of rating perception of exertion, the subjective perceptions of fatigue were evaluated at the end of each week, through the well-being scale and the vertical jump with counter movement was evaluated at the end of each stage. The results showed higher internal training load values in Stage 1 compared to Stage 2 (p = 0.02) and Stage 3 (p = 0.01), changes in the athletes' state of well-being during the three stages analyzed, considering the fatigue indicators (F = 13.1; p < 0.001), stress (F = 23.8; p < 0.001), mood (F = 16.7; p < 0.001) and total well-being (F = 11.2; p < 0.001) and also significant changes in vertical jump with counter movement at different moments of assessment (F = 7.2; p < 0.01). It is concluded that the distribution of internal training load contributes to an improvement in performance in the vertical jump with counter movement and also a reduction in the perception of fatigue at the end of the pre-season.

Avaliação do controle postural em praticantes de dança de salão / Evaluation of postural control in practitioners of ballroom dancing

Este estudo teve como objetivo analisar o efeito imediato da prática de dança de salão sobre o controle postural estático de seus praticantes, juntamente aos fatores que possam influenciá-lo. Optou-se por um estudo transversal de caráter observacional quantitativo em uma amostra por conveniência, constituída por 19 homens e 19 mulheres praticantes de dança de salão, que participaram de uma prática de dança de 120 minutos. Foram coletados os dados sociodemográficos, antropométricos e sintomas osteomusculares. Para a avaliação do centro de pressão (COP), foi utilizado uma plataforma de força antes e depois da prática. O único fator que demonstrou diferença significativa no controle postural antes da prática de dança foi o sexo, sendo os homens que apresentam maiores deslocamentos no COP. Comparando o efeito da prática de 120 minutos de dança, em todos os participantes, houve uma diminuição do deslocamento do COP na posição bipodal no COPap (p= 0.028) e COPvel (p= 0.003), na posição unipodal COPvel (p= 0.006) e na posição semi-tandem COPml (p= 0.026). O efeito imediato de uma prática de dança de salão contribui para o controle postural em ambos os sexos. (AU)

This study aimed to analyze the immediate effect of the practice ballroom dancing on the static postural control of its practitioners, along with factors that can influence it. We opted for a cross-sectional study of quantitative observational in a sample of convenience of 19 men and 19 women practitioner's ballroom dancing, who participated in a dance practice about 120 minutes. We collected sociodemographic data, anthropometric and musculoskeletal symptoms. For the evaluation of center of pressure (COP), was used a force platform before and after practice. The only factor that demonstrated a significant association with postural control prior to dance practice was the genre, men show greater displacements at the COP. Comparing the effect of the practice of 120 minutes of dance, in all participants, a decrease in COP displacement in the bipedal position in COPap (p = 0.028) and COPvel (p = 0.003), in the single-leg position COPvel (p = 0.006) and in the semi-tandem position COPml (p = 0.026). The immediate effect of a ballroom practice contributes to postural control in both sexes. (AU)

Flexibility and achilles tendon: a brief review / Flexibilidade e tendão de aquiles: uma breve revisão

Performing flexibility training in an exercise program is important to improve range of motion (ROM). Tendons have a profound impact on the general function of the musculoskeletal system, influence the limitation of ROM, and its structure and mechanical properties can benefit from stretching protocols. The systematic use of lower limbs in locomotion caused the Achilles tendon to become the largest and strongest tendon in the human body. Therefore, understanding the best prescription and frequency of flexibility exercise leads to changes in tendon properties is essential for an appropriate and effective exercise routine. Thus, the aim of this review was to organize and discuss publications about the implications of triceps surae stretching in ROM, as well as its influence on tendon properties. Acute studies show that continuous stretching times between five and 10 minutes cause decreased tendon stiffness, which is not seen in fractionated stretching times less than five minutes. Chronic studies, in turn, also don't present significant results in stiffness with fractionated times and studies with continuous times were not found. Thus, it is not possible to know if a continuous stretching time (longer than one minute) or a total time longer than five minutes but fractionated, can influence the tendon stiffness. (AU)

A realização de treino de flexibilidade como rotina em um programa de exercícios é importante para melhorar amplitude de movimento (ADM). Os tendões têm um impacto profundo na função geral do sistema musculoesquelético, influenciam na limitação da ADM, e sua estrutura e propriedades mecânicas podem se beneficiar de protocolos de alongamento. O uso sistemático dos membros inferiores na locomoção fez com que o tendão de Aquiles se tornasse o maior e mais forte tendão do corpo humano. Portanto, entender qual a melhor prescrição e frequência de exercício de flexibilidade para que ocasione alterações nas propriedades tendíneas é essencial para uma rotina de exercícios adequada e eficaz. Sendo assim, o objetivo dessa revisão de literatura foi organizar e discutir publicações sobre as implicações do alongamento do tríceps sural na ADM, bem como sua influência nas propriedades tendíneas. Estudos agudos mostram que tempos contínuos entre cinco e 10 minutos de alongamento estático causam diminuição da rigidez tendínea, o que não é visto em tempos intervalados inferiores a cinco minutos. Os estudos crônicos, por sua vez, também não apresentam resultados significativos na rigidez com protocolos de alongamento intervalados e estudos com protocolos contínuos não foram encontrados. Dessa forma, não é possível saber se um tempo contínuo de alongamento (superior a um minuto) ou um tempo superior a cinco minutos, intervalado, podem influenciar na rigidez tendínea. (AU)

A single-center retrospective analysis of 77 traumatic arterial injuries of lower extremities / 中华外科杂志

Objective: To analyze the treatment and clinical prognosis of lower extremity arterial injury caused by trauma. Methods: The clinical data of 77 patients with traumatic lower extremity arterial injury admitted to Department of Vascular Surgery,Yichang Central People's Hospital from January 2013 to June 2021 were collected retrospectively. There were 65 males and 12 females, with an average age of 47.4 years (range: 7 to 75 years). Among the 77 patients, 56 cases (72.7%) had open injury and 21 cases (27.3%) had closed injury. Iliac artery was injured in 9 cases (11.7%), common femoral artery in 7 cases (9.1%), superficial femoral artery in 1 case (1.3%), popliteal artery in 11 cases (14.3%) and inferior knee artery in 49 cases (63.6%). The treatment methods and clinical effects were analyzed. Results: One case with pelvic fracture combined the internal iliac artery injury and 1 case with multiple injuries involving the common femoral artery died of circulatory failure before surgery. Seventy-five cases received vascular-related operations, including arterial ligation in 24 cases, arterial reconstruction in 40 cases, stent graft implantation in 1 case, primary amputation in 2 cases, and arterial embolization in 8 cases. The overall mortality rate was 6.5% (5/77), all of which were closed injuries. Except for 2 cases who died before surgery, 3 cases with pelvic fracture combined the internal iliac artery injury died of multiple organ failure after internal iliac artery embolization. There were 8 cases received amputation (10.4%, 8/77), 5 cases with closed injury and 3 cases with open injury. In addition to 2 cases with primary amputation, 6 cases underwent secondary amputation due to ischemia-reperfusion injury after revascularization (4 cases with popliteal artery injury and 2 cases with subpatellar artery injury). The average followed-up time was 17 months (range: 2 months to 8 years). One patient with femoral artery injury underwent autologous great saphenous vein bypass, and lower limb artery CT angiography was re-examined 6 months after the operation, and 30% distal anastomotic stenosis was found. Ankle brachial index<0.8 was found in two patients 1 year after popliteal artery repair, but none of the patients had intermittent claudication symptoms, and no further intervention was performed. Five patients suffered delayed healing due to severe lower limb injury, fracture and skin injury. Among them, 2 cases had poor wound healing at the stump of amputation, which gradually healed 3 to 5 months after several debridements. The other 3 vascular injury combined with tibial fracture patients had delayed tibial healing after surgery, but no symptoms of vascular ischemia occurred. All the other patients recovered well and no other serious complications occurred. Conclusions: The proportion of death and disability in patients with lower limb artery injury caused by trauma is high. Active and orderly surgical repair according to the site and type of injury can reduce the mortality, save the function of the affected limb, and promote the healing of injury.

Clinical characteristics of patients with rheumatoid arthritis complicated with venous thrombosis of lower extremities / 北京大学学报(医学版)

OBJECTIVE@#To analyze the clinical characteristics of patients with rheumatoid arthritis (RA) complicated with venous thrombosis of lower extremities, and to improve the awareness of this condition.@*METHODS@#The clinical and laboratory data of 502 RA patients hospitalized in Department of Rheumatology and Immunology Peking University Third Hospital from November 1, 2013 to December 31, 2020 were collected, retrospective analysis was made on the RA patients who were diagnosed with lower limb vein thrombosis on discharge but hadn't on admission, the patients in this group were defined as thrombosis group, and the other patients without lower limb vein thrombosis were taken as control group. Single factor analysis was conducted between the two groups. Then multivariate Logistic regression analysis was used to analyze the independent risk factors of RA complicated with lower limb venous thrombosis with statistical significance in univariate analysis.@*RESULTS@#There were 34 patients (6.77%) in the thrombosis group and 468 patients (93.23%) in the control group. The age of thrombosis group was 34-86 years (median age was 71 years); 23 were female and 11 were male; there were 20 cases with unilateral lower limb vein thrombosis and 14 cases with bilateral lower limb vein thrombosis; pulmonary embolism in 3 cases (low risk).In the thrombosis group 17 (50.0%) patients were bedridden for more than one week or needed crutches/wheelchairs before admission. 29 cases(85.3%)had large joint involvement of lower extremities, including 22 cases of knee joint involvement, 1 case of hip joint involvement, 2 cases of ankle joint involvement, and 4 cases with both knee and hip joint involvement. In the thrombosis group, the high, middle and low disease activity scores 28(DAS28) were 23 (67.6%), 9 (26.5%) and 2 (5.9%), respectively. There were 21 patients in the thrombosis group had completed thrombosis related examinations, only 4 patients were positive for anti-cardiolipin antibody or anti-β2 glycoprotein 1 antibody or lupus anticoagulant, the rests were all negative. In the thrombosis group, age and platelet (PLT) level were significantly higher than those in the control group [71 (60, 77) years vs. 60 (51, 68) years, Z=-3.873, P < 0.01, (328.53× 109±119.06 × 109) /L vs.(278.68 × 109±104.50 × 109)/L, t=2.660, P < 0.01, respectively]. The proportion of D-Dimer increased in the thrombosis group as well as the positivity rheumatoid factor (RF) was much higher than those in the control group (94.1% vs.66.4%, χ2=11.192, P < 0.01; 85.3% vs.67.1%, χ2=4.852, P < 0.05, respectively). Multivariate Logistic regression analysis showed that age (OR=1.063, 95%CI: 1.026-1.101, P=0.001), D-Dimer increased (OR=4.968, 95%CI: 1.136-21.730, P=0.033) and PLT level (OR=1.004, 95%CI: 1.001-1.007, P=0.022) were the independent risk factors for RA complica-ted with lower extremity venous thrombosis.@*CONCLUSION@#RA patients have potential risk of thrombosis of lower extremities. For the older age, D-Dimer and PLT elevated, especially those who were bedridden, RF positive and had high disease activity, should be alert to the risk.

Clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux / 中华烧伤杂志

Objective: To explore the clinical effects of free superficial peroneal artery perforator flaps in repairing skin and soft tissue defects of the hallux. Methods: A retrospective observational study was conducted. From January 2020 to January 2021, 13 patients with skin and soft tissue defects of the hallux who met the inclusion criteria were admitted to Department of Foot and Ankle Surgery of Ruihua Affiliated Hospital of Soochow University, including 12 males and 1 female, aged 26 to 53 years. Before operation, the perforating point of the superficial peroneal artery perforator was located by color Doppler ultrasound on the calf on the same side of the affected hallux and marked on the body surface. The operation was performed under spinal anesthesia combined with continuous epidural anesthesia. The area of skin and soft tissue defect after debridement was 4.5 cm×2.5 cm to 12.0 cm×3.0 cm. According to the size and shape of the wound, the superficial peroneal artery perforator flap was designed with the line between the fibular head and the lateral malleolus tip parallel shifting 2 cm to the tibial side as the flap axis line, and the perforating point of the perforator near the midpoint of the axis line as the center. The cut area of the flap was 5.0 cm×3.0 cm to 13.0 cm×4.0 cm, and part of the deep fascia was cut when the pedicle was freed. The donor site wound was sutured directly. During the operation, the number and type of the perforator and the cutting time of the flap were recorded, and the length of the perforator pedicle and diameter of the perforator were measured. The survival of the flap, the healing time and the healing condition of the donor and recipient areas were recorded after operation. The color, texture, elasticity of the flap, standing and walking functions of patients, the recovery of the donor area, and the patients' satisfaction with the recovery of the donor and recipient areas were recorded during the follow-up. At the last follow-up, the sensation of the flap was evaluated by the British Medical Association sensory function evaluation standard, the function of the affected limb was evaluated by the American Society of Foot and Ankle Surgery scoring system, and the excellent and good rate of the function of the affected limb was calculated. Results: A total of 13 perforators of the superficial peroneal artery were detected during the operation, all of which were septocutaneous perforators, and the perforator diameter was 0.3 to 0.5 mm. The vascular pedicle length was 2 to 5 cm. Flap cutting time was 11 to 26 minutes. The flaps of 13 patients all survived completely. The wounds at the donor and recipient sites healed well 9 to 18 days after operation. During follow-up of 6 to 14 months, the flaps had good color, texture, and elasticity; 11 patients had no obvious bloated appearance, and the other 2 patients underwent flap thinning and plastic surgery in the second stage because of their bloated appearance; all the patients returned to normal walking and standing functions. There was only one linear scar left in the donor site, with no obvious scar hyperplasia or hyperpigmentation. All the patients were satisfied with the recovery of the donor and recipient areas. At the last follow-up, the sensation of the flap was evaluated as grade S3 in 2 cases, grade S2 in 9 cases, and grade S1 in 2 cases; the function of the affected limb was evaluated as excellent in 7 cases and good in 6 cases, with an excellent and good rate of 100%. Conclusions: The free superficial peroneal artery perforator flap has relatively constant vascular anatomy, which is thin and wear-resistant, with less damage to the donor site after flap excision, and can preserve the shape and function of the hallux to the greatest extent. It is an effective method for repairing skin and soft tissue defect of the hallux.

Efficiency of electrocardiogram monitor for positioning the catheter tip in the central catheter placement via lower extremity veins in neonates: a randomized controlled study / 中国当代儿科杂志

OBJECTIVES@#To study the efficiency of electrocardiogram (ECG) monitor for positioning the catheter tip in the placement of peripherally inserted central venous catheterization (PICC) via lower extremity veins in neonates.@*METHODS@#A total of 120 neonates who were admitted to the neonatal intensive care unit from January 2020 to January 2022 and received PICC via lower extremity veins were enrolled and divided into a control group and an observation group using a random number table (n=60 each). The neonates in the control group were given body surface measurement and postoperative chest X-ray localization, and those in the observation group were given body surface measurement, ECG-guided positioning, and postoperative chest X-ray localization. The two groups were compared in terms of general information, one-time success rate of PICC placement, and time spent on PICC placement, and the efficiency of ECG-guided positioning was evaluated.@*RESULTS@#Compared with the control group, the observation group had a higher one-time success rate of PICC placement (92% vs 75%; P<0.05) and a shorter time spent on PICC placement [(26.5±3.0) min vs (31.8±2.8) min; P<0.05]. ECG-guided positioning had a sensitivity of 90.9% and a specificity of 100% in the PICC placement via lower extremity veins in neonates.@*CONCLUSIONS@#ECG monitor helps to determine the position of catheter tip in the PICC placement via lower extremity veins in neonates and can improve the one-time success rate of PICC placement and reduce the time spent on PICC placement, with a good positioning efficiency.

Weakness in both lower limbs for 1 week and blepharoptosis for 3 days in a boy aged 1 year and 7 months / 中国当代儿科杂志

A boy, aged 1 year and 7 months, was hospitalized due to weakness in both lower limbs and blepharoptosis, which showed progressive aggravation and developed into irregular breathing. Neurological examinations showed lethargy, blepharoptosis, grade 4 muscle strength of both upper limbs, grade 3 muscle strength of both lower limbs, and disappearance of tendon reflex. Laboratory tests revealed albuminocytological dissociation in cerebrospinal fluid, disappearance of H reflex, and positive serum anti-GD1b IgG. The boy was finally diagnosed with Guillain-Barré syndrome (GBS) overlapping with Miller-Fisher syndrome and Bickerstaff brainstem encephalitis. He recovered and was discharged after treatment including immunoglobulin, plasma exchange, and respiratory support. The GBS overlap syndromes in children have strong clinical heterogeneity due to the injury of both peripheral nerve and brainstem, among which anti-GD1b antibody-related GBS overlap syndromes have special clinical manifestations and complex neuroelectrophysiological changes and are thus difficult to diagnose. Nerve conduction velocity tests, especially H reflex test, should be performed for children with weakness in both lower limbs and blepharoptosis.

Intracapsular fracture of the proximal femur in a bilateral above-knee amputee: A case report with technical tips for intraoperative positioning and literature review / 中华创伤杂志(英文版)

Intracapsular fractures of the proximal femur are one of the most common fractures of the lower limbs. Most cases require osteosynthesis with suitable implants, and intraoperative positioning of the patient on the fracture table is a prerequisite to facilitate fracture manipulation, traction, reduction and fluoroscopy assessment. However, positioning the limbs of bilateral above-knee amputees for internal fixation of related proximal femoral fractures is a difficult task, which requires customized inventory for effective limb positioning and fracture manipulation. This study reported a rare case following a crush injury of bilateral lower limb in a road traffic accident, and described some technical tips of acute femoral neck fractures in bilateral above-knee amputation. The patient was managed with immediate guillotine amputation and later secondary wound closure followed by internal fixation of the right-sided femoral neck fracture with multiple cancellous cannulated screws.

Prevalence and risk factors of deep venous thrombosis of lower extremity in patients with stage Ⅲ and Ⅳ pressure ulcers on admission / 中华烧伤杂志

Objective: To investigate the incidence and risk factors of deep venous thrombosis (DVT) of lower extremity in patients with stage Ⅲ and Ⅳ pressure ulcer on admission. Methods: A retrospective case series study was conducted. A total of 241 patients with stage Ⅲ and Ⅳ pressure ulcers who met the inclusion criteria and were discharged from the Department of Wound Repair of the First People's Hospital of Zhengzhou from January 1, 2015 to December 31, 2019 were enrolled in this study, including 134 males and 107 females, aged 22 to 93 years, with a median age of 68 years; 37 patients were with stage Ⅲ pressure ulcers and 204 patients were with stage Ⅳ pressure ulcers. The DVT occurrence of patients was recorded. According to whether DVT of lower extremity veins was diagnosed by color Doppler ultrasound within 48 h after admission or not, the patients were divided into DVT group (n=37) and non-DVT group (n=204). Data of patients in the two groups were collected and compared, including gender, age, duration of pressure ulcer, time in bed, and combination with diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia, sepsis/septic shock, and paraplegia, and the plasma D-dimer level and Caprini score within 24 h after admission. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. The indicators with statistically significant differences between the two groups were analyzed with multivariate logistic regression analysis to screen the independent risk factors influencing the DVT of lower extremity in 241 patients with stage Ⅲ and Ⅳ pressure ulcers on admission. Results: The incidence of DVT of lower extremity was 15.4% (37/241), of which 86.5% (32/37) were asymptomatic DVT. Among the DVT of 46 lower limbs, only 29 involved the inferior genicular veins, accounting for 63.0%. There were no statistically significant differences in gender, duration of pressure ulcer, combination with diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia, and sepsis/septic shock of patients between the two groups (P>0.05), while there were statistically significant differences in age, time in bed, combination with paraplegia, the plasma D-dimer level and Caprini score of patients between the two groups(t=-3.19, Z=-2.04, χ2=4.44, Z=-3.89, t=-2.14, respectively, P<0.05 or P<0.01). Multivariate logistic regression analysis showed that age and plasma D-dimer level were independent risk factors influencing the DVT of lower extremity in 241 patients with stage Ⅲ and Ⅳ pressure ulcers on admission (with odds ratios of 1.03 and 1.18, respectively, with 95% confidence intervals of 1.00-1.06 and 1.05-1.33, respectively, P<0.05 or P<0.01). Conclusions: The patients with stage Ⅲ and Ⅳ pressure ulcers have a higher incidence of DVT on admission, with age and plasma D-dimer level being the independent risk factors for DVT of lower extremity. It is necessary to pay attention to the targeted screening of DVT and education of its prevention.

Novel apical-to-femoral rail technique for horizontal aorta in transcatheter aortic valve replacement / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Transcatheter aortic valve replacement (TAVR) has emerged as a viable treatment option for patients with severe aortic stenosis regardless of its surgical risk stratification (Otto et al., 2021). Aortic angulation is usually measured as the angle between the horizontal and the aortic annulus planes based on preproced‍ural multidetector computed tomography (MDCT) (Al-Lamee et al., 2011). Extremely horizontal aorta, defined as an aortic angulation greater than 70°, is an unfavorable anatomic structure that poses particular technical challenges for TAVR. Abramowitz et al. (2016) have proved that an extremely horizontal aorta increased the risk of procedural complications, such as lower device success rates, more moderate or even severe perivalvular leakage (PVL), and the need for second valve implantation. Because of the long stent frame, inflexibility, and non-steerability, it is challenging to pass the delivery system of self-expanding valves (SEVs) through an extremely horizontal aorta. As a result, patients with an extremely horizontal aorta have always been excluded from the clinical trials of TAVR, and transfemoral (TF)-TAVR with SEV is considered as an "off-label" use of TAVR (Adams et al., 2014; Kaneko et al., 2020). Herein, we present a technically difficult case, in which a patient with an extremely horizontal aorta underwent TF-TAVR with SEV by applying a unique apical-to-femoral rail strategy.

Effects of Interactive Dynamic Scalp Acupuncture on Motor Function and Gait of Lower Limbs after Stroke: A Multicenter, Randomized, Controlled Clinical Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on motor function and gait of the lower limbs in post-stroke hemiplegia patients.@*METHODS@#A total of 231 patients with post-stroke hemiplegia was randomly divided into IDSA (78 cases), SCT (78 cases), and TSA (75 cases) groups by a random number table. Scalp acupuncture (SA) and lower-limb robot training (LLRT) were both performed in the IDSA and SCT groups. The patients in the TSA group underwent SA and did not receive LLRT. The treatment was administered once daily and 6 times weekly for 8 continuous weeks, each session lasted for 30 min. The primary outcome measures included Fugl-Meyer assessment of the lower extremity (FMA-LE), berg balance scale (BBS), modified barthel index (MBI), and 6-min walking test (6MWT). The secondary outcome measures included stride frequency (SF), stride length (SL), stride width (SW), affected side foot angle (ASFA), passive range of motion (PROM) of the affected hip (PROM-H), knee (PROM-K) and ankle (PROM-A) joints. The patients were evaluated before treatment, at 1- and 2-month treatment, and 1-, and 2-month follow-up visits, respectively. Adverse events during 2-month treatment were observed.@*RESULTS@#Nineteen patients withdrew from the trial, with 8 in the IDSA and 5 in the SCT groups, 6 in the TSA group. The FMA-LE, BBS, 6MWT and MBI scores in the IDSA group were significantly increased after 8-week treatment and 2 follow-up visits compared with the SCT and TSA groups (P<0.05 or P<0.01). Compared with pre-treatment, the grade distribution of BBS and MBI scores in the 3 groups were significantly improved at 1, 2-month treatment and 2 follow-up visits (P<0.05 or P<0.01). The SF, PROM-H, PROM-K and PROM-A in the IDSA group was significantly increased compared with the SCT and TSA groups after 8-week of treatment (P<0.05 or P<0.01). Compared with the SCT group, ASFA of the IDSA group was significantly reduced after 8-week of treatment (P<0.05). SF, SL, PROM-K and PROM-A were significantly increased at the 2nd follow-up visit whereas the ASFA was significantly reduced in the IDSA group compared with the SCT groups at 1st follow-up visit (P<0.05 or P<0.01). The SF was significantly increased in the SCT group compared with the TSA group after 8-week treatment (P<0.05). Compared with the TSA group, PROM-K, PROM-A were significantly increased at the 2nd follow-up visit (P<0.05).@*CONCLUSIONS@#The effects of IDSA on lower-limb motor function and walking ability of post-stroke patients were superior to SCT and TSA. The SCT was comparable to TSA treatment, and appeared to be superior in improving the motion range of the lower extremities. (Registration No. ChiCTR1900027206).
