ABSTRACT
Objective: To study the protective effect of parachute ankle brace on ankle joint during simulated parachuting landing. Methods: In August 2021, 30 male paratroopers were selected as the test subjects by simple random sampling method. They jumped from the 1.5 m and 2.0 m height platforms respectively with and without parachute ankle brace, and landed on the sandy ground in a semi-squat parachute landing position. The experiment was divided into 1.5 m experimental group and control group and 2.0 m experimental group and control group. Angle sensor and surface electromyograph were used to measure and analyze the coronal tilt range of the ankle joint and the percentage of maximal voluntary contraction (MVE%) of the muscles around the ankle joint, respectively, to evaluate the protective effect of the parachute ankle brace. Results: At the same height, the tilt range of coronal plane of ankle in experimental group was significantly reduced compared with control group, and the difference was statistically significant (P<0.05). Under the same protection state, the tilt range of the coronal plane of the ankle in the 1.5 m group was significantly reduced compared with that in the 2.0 m group, and the difference was statistically significant (P<0.05). The coronal plane inclination range of the ankle in 2 m experimental group was significantly lower than that in 1.5 m control group, and the difference was statistically significant (P<0.05). Compared with 1.5 m control group, MVE% of right tibialis anterior muscle and bilateral lateral gastrocnemius decreased in 1.5 m experimental group, while MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle and right lateral gastrocnemius decreased in 2.0 m experimental group, while the MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). The MVE% of bilateral tibialis anterior muscle, bilateral lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m experimental group decreased compared with 2.0 m experimental group, and the differences were statistically significant (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle, right lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m control group decreased, and the differences were statistically significant (P<0.05) . Conclusion: Wearing parachute ankle brace can effectively limit the coronal plane inclination range of ankle joint, improve the stability of ankle joint and reduce the load on the muscles around ankle joint by landing. Reducing the height of the jumping platform can reduce the coronal plane incline range of the ankle and the muscle load around the ankle during landing.

Background: Nail braces are reportedly effective for treating both acute inflamed and chronic dystrophic type ingrown toenails. Aims: In this study, risk factors for poorly controlled and recurrence-prone ingrown toenails treated with nail braces were identified. Methods: We performed a retrospective study on patients with ingrown toenails between June 1, 2015, and May 31, 2018. The last follow-up date was January 31, 2019. Multivariate logistic regression was performed to evaluate the possible factors associated with poorly controlled status (ongoing paronychia during treatment) and recurrence. Results: There were 120 (244 sides) and 118 patients (167 sides) with chronic dystrophic and acute inflamed type ingrown toenails, respectively. The mean treatment duration and follow-up period were 161.2 ± 98.3 days and 432.7 ± 320.9 days, respectively. Poor control and recurrence were seen in 7.3% (17/232) and 12.2% (27/221) of the patients, respectively. In the multivariate analysis, acute inflamed ingrown toenails, previous nail avulsion, proximal nail fold hypertrophy and more than one affected side remained significantly associated with poorly controlled ingrown toenails. Foot bone deformity was significantly associated with recurrence. Limitations: This study was a retrospective study so that confounding factors such as comorbidities, body mass index, accompanying nail changes and lifestyle could not be evaluated. Conclusion: Several risk factors related to poor control and recurrence were identified. Patients could therefore benefit from more suitable treatment plans with reasonable expectation.
ABSTRACT
ObjectiveTo investigate the immediate effect of wearing a soft ankle brace on dynamic and static balance function and biomechanics of affected lower limbs during walking in chronic ankle instability (CAI) patients. MethodsFrom January to August, 2021, 40 CAI patients from Musculoskeletal Rehabilitation Center, Beijing Rehabilitation Hospital, Capital Medical University were measured dynamic and static balance indexes with Zebris FDM-System and Y balance test, before and after wearing a soft ankle brace; while the kinetics indexes and surface electromyography of the affected lower extremities during walking were collected with Zebris FDM-System and a surface electromyography telemeter simultaneously. ResultsThe velocity and area of center of pressure reduced in both open and closed eye modes (|t| > 2.876, P < 0.01), the Y-balance scores increased in all the directions (|t| > 21.212, P < 0.001) after wearing brace; while the peak pressures and impulses increased in the midfoot and medial forefoot regions (|t| > 2.057, P < 0.05), and decreased in the lateral heel, lateral forefoot and toe regions (|t| > 2.464, P < 0.05), and the root mean square of surface electromyography increased in the tibialis anterior and lateral gastrocnemius (|t| > 2.159, P < 0.05) during walking. ConclusionWearing soft brace can immediately improve dynamic and static balance of CAI patients, and optimize plantar kinetic distribution and enhance activation of the anterior tibial and the lateral head of gastrocnemius of the affected limb during walking, to improve motor control of CAI patients.
ABSTRACT
Objective To examine the effects of ankle brace on biomechanics of the lower extremity during landing, so as to provide a theoretic support to choose ankle brace for people with different sports levels. Methods The key words (ankle brace OR ankle braces OR ankle bracing OR ankle support) AND (landing OR land OR jump OR hopped OR hopping) AND (biomechanics OR kinematics OR kinetics OR electromyography OR neuromuscular) in Chinese and English were searched from different electronic databases (CNKI, Web of Science, EBSCO, PubMed and other databases), for a period of Jan. 2000 to Dec. 2020. Cochrane was used to evaluate the quality of eligible studies. For meta analysis, subgroup analysis was used to assess the impact of ankle braces on ankle biomechanics.Results Thirteen studies with a total of 222 participants were included for mata analysis in this study. The semi-rigid ankle brace reduced the peak of ankle inversion by 25.8% compared with the elastic ankle brace (SMD=-0.562, P<0.001). Moreover, the elastic ankle brace reduced ankle plant flexion during landing among athletes (SMD=-3.42, P=-0.021). As for collagiate students, both elastic ankle and semi-rigid ankle decreased the ankle inversion (elastic ankle brace: 35.4%, SMD=-1.000, P=-0.013; semi-rigid ankle brace: 31.11%, SMD=-0.881, P<0.001) and ankle plant flexion (elastic ankle brace:23.30%, SMD=-1.381, P<0.001;semi-rigid ankle brace: 36.33%, SMD=-1.605, P<0.001).Conclusions Both ankle braces can prevent ankle sprain for athletes (basketball, volleyball, running) who experience training more than 5 years. The elastic ankle brace can limit the inversion and plantar flexion, while the semi-rigid ankle brace can merely decrease the ankle inversion. Therefore, athletes are more suitable for the elastic ankle brace. As for collegiate students without training history, both ankle brace can decrease the ankle inversion and plantar flexion. The elastic ankle brace has greater restriction on inversion, while the semi-rigid ankle brace has more restriction on plantar flexion. Therefore, the elastic ankle brace should be utilized if collegiate students have calcaneofibular ligament injury, while the semi-rigid ankle brace is more suitable for collegiate students who have a history of anterior talofibular ligament injury.
ABSTRACT
Objective：In athletes who are still in the growing period, lumbar spondylolysis is mainly treated with brace therapy to enable bone fusion. During the brace period, sports activities are often discontinued. The purpose of this study was to investigate how the combination of brace therapy and early physiotherapy affects the duration of return to play in athletes with lumbar spondylolysis.Methods：Thirty-seven athletes in the growing period with unilateral spondylolysis were included in the study. They were classified into two groups：17 patients who rested during the brace period（brace group）and 20 patients who combined the brace with early physical therapy (combination group). The examined items were duration of the brace period and duration from the end of the brace therapy to return to play (return period). Both these items were compared between the brace group and the combination group. In addition, the union rate of both groups was also calculated.Results：The return period was significantly shorter in the combination group than in the brace group. However, there were no statistically significant differences between the groups with respect to other data.Conclusion：Since there was no significant difference in the duration of the brace period and the union rate between both groups, we believe that early physical therapy intervention does not adversely affect bone union in athletes with spondylolysis who are in the growing period. Therefore, it is considered that the combined use of brace therapy and early physical therapy can maintain flexibility and muscular strength during the brace period and can enable a smooth transit to playing after the bone union is complete.
ABSTRACT
Objective:To observe the effect of braces combined with insoles on scoliosis and walking performance in patients with adolescent idiopathic scoliosis (AIS). Methods:From September, 2019 to September, 2020, 42 subjects with AIS were selected and randomly divided into brace group (n = 21) and brace combined with insole group (n = 21). Both groups received two-month routine rehabilitation, including braces for 22 to 23 hours a day and gymnastics for 30 minutes a day. The brace combined with insole group additionally wore insoles, at least eight hours a day for two months. Meanwhile, 32 even-aged adolescents were recruited as healthy controls. Firstly, gait and plantar pressure of 42 patients and 32 healthy adolescents were compared to find out abnormal indicators. Secondly, the scoliosis and above abnormal indicators were compared between the brace group and the brace combined with insole group Results:The center of pressure excursion index (CPEI) was higher in AIS group than in the healthy group (F = 3.120, P < 0.05), and there was no significant difference in walking speed, gait cycle and phase between two groups (P>0.05). An obvious imbalanced pressure was observed between the medial and lateral heel of the single foot and the bilateral foot in AIS patients (P < 0.05). After treatment, the Cobb's angle decreased in AIS patients (t > 7.552, P < 0.001), however, no difference was found between the brace group and the brace combined with insole group (t = 0.459, P > 0.05); the CPEI decreased (t = 2.209, P < 0.05), and the pressure in medial and lateral heel as well as the left and right foot tended to be balanced (t > 2.306, P < 0.05) in the brace combined with insole group, and were better than that of the brace group (|t| > 2.319, P < 0.05). Conclusion:Plantar pressure distribution shows obvious local and global asymmetric changes in AIS patients. The efficacy of insoles on the scoliosis is limited, but the insole can effectively improve the abnormal biomechanics and balance the force.

ABSTRACT
BACKGROUND: Knee braces have been shown to improve knee mechanics in the case of slow walking, but most studies lack the data regarding the effects of a brace on knee injury in the case of lack of movement. OBJECTIVE: Jumping, emergency stop, rotation which easily induce knee joint injury during the rapid exercise were simulated to investigate whether silicon mesh braces can provide stable support for the knee joint and provide data support for the protection against anterior cruciate ligament injury. METHODS: Twelve healthy subjects were selected to perform three movements: Squatting, one-leg jump and steering jump respectively with and without a brace. Reflection markers were placed on the feet, calves, thighs, and pelvis of the subjects. A Qualisys motion capture system was used to obtain kinematic data of the knee joints. Knee joint motion was compared between with and without a brace. This study was performed by Medical Ethics Committee of Guizhou College of Traditional Chinese Medicine on August 8, 2018 (approval No. 2018661). RESULTS AND CONCLUSION: There were significant differences in the angle and angular velocity of the knee joint among sagittal plane, coronal plane, and horizontal plane. The knee joint valgus and internal rotation angle were reduced when wearing a brace in particular in one-leg jump and steering jump. The angular velocity of horizontal surface rotation also decreased obviously when wearing a brace. These findings suggest that wearing a brace can affect the motion mechanics of the knee joint in the coronal and horizontal planes. This suggests that knee joint can effectively control the stability when wearing a brace in the process of dynamic movement, and wearing a brace can improve the control of knee peak valgus angular velocity and external rotation angular velocity, which can help effectively prevent anterior cruciate ligament injury of patients with anterior cruciate ligament defects.
ABSTRACT
BACKGROUND: 3D printing external fixation fixture can make individualized external fixation scheme for fracture patients and is easy to wear. Zicao oil (a Chinese traditional medicine oil) for trauma treatment has the effect of reducing swelling and removing blood stasis to assist the rehabilitation treatment of fracture. The combination of the two could benefit the rehabilitation of patients with fracture conservative treatment. OBJECTIVE: To investigate the clinical application value of the 3D printed orthopedic cast combined with Zicao oil in the treatment of distal radial fracture, hoping to provide a basis for the further study of a combined Chinese and western medicine treatment scheme for the recovery of wrist function after distal radius fractures. METHODS: Sixty-four patients with distal radial fracture were selected and randomly divided into two groups. Patients in the trial group received 3D-printed cast combined with Zicao oil treatment after manual reduction. Patients in the control group received traditional splint cast combined with Zicao oil after manual reduction. The Jakim scoring for distal radial fracture treatment, as well as pain degree, swelling degree, wrist range of motion, grasping ability and deformity degree were evaluated and compared 2 weeks after removal of external fixation in both groups. RESULTS AND CONCLUSION: (1) The excellent and good rate was 94% in the trial group and 78% in the control group. There was significant difference between the two groups (P < 0.01). (2) At 2, 4, 8 and 14 days after treatment, the scores of wrist range of motion and visual analogue scale were significantly better than those before treatment (P < 0.01). At different time points after treatment, the scores of wrist range of motion and visual analogue scale in the trial group were significantly better than those in the control group (P < 0.05). (3) The swelling degree of the trial group was better than that of the control group 2, 4, 8 and 14 days after treatment (P < 0.05). (4) The results show that 3D printed cast combined with Zicao oil is effective in the treatment of distal radius fracture, can effectively improve the function of wrist joint, reduce the pain of patients and improve the quality of rehabilitation.
ABSTRACT
Identifying maize genotypes with favorable root architecture traits for drought tolerance is prerequisite for initiating a successful breeding program for developing high yielding and drought tolerant varieties of maize. The aims of the present study were: (i) to identify drought tolerant genotypes of maize at flowering and grain filling, (ii) to interpret the correlations between the drought tolerance and root architecture traits and (iii) to identify the putative mechanisms of drought tolerance via root system traits. An experiment was carried out in two years using a split plot design with three replications. The main plots were assigned to three water stress levels, namely: well watering (WW), water stress at flowering (WSF) and water stress at grain filling (WSG), and sub-plots to 22 maize cultivars and populations. Drought tolerance index (DTI) had strong and positive associations with crown root length (CRL), root circumference (RC) and root dry weight (DRW) under both WSF and WSG, a negative correlation with brace root whorls (BW), and positive correlations with crown root number (CN) under WSF and brace root branching (BB) and crown root branching (CB) under WSG. These root traits are therefore considered as putative mechanisms of drought tolerance. The cultivars Pioneer-3444, SC-128, Egaseed-77, SC-10 and TWC-324 showed the most drought tolerant and the highest yielding in a descending order; each had a number of such drought tolerance mechanisms. Further investigation should be conducted to determine the underlying root mechanisms contributing to the selection of water-efficient hybrids of maize.
ABSTRACT
Over 500,000 women die each year due to complications of pregnancy and childbirth, a number that has remained relatively unchanged since 1990, when the first global estimates of the burden of maternal mortality were developed. Hemorrhage due to uterine atony, adherent placenta and PPH are still the causes of maternal death in developing countries. Although advances have been made in the development of conservative medical and surgical treatment of obstetric haemorrhage like brace sutures, internal iliac artery ligation, selective arterial embolization etc emergency obstetric hysterectomy remains a lifesaving procedure in the management of intractable haemorrhage unresponsive to conservative management.

PURPOSE: To improve pulmonary function and decrease in balance ability with increasing forward head position and vertebral curvature, we applied Figure-8 brace to confirm the immediate effect on vital capacity and balance and to see if it is applicable. METHODS: A total of 34 elderly women aged 65 or older and young women in their 20s with FHP were screened to measure vital capacity, measuring the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), and measuring the foot pressure to see the change in balance. For statistical analysis, the difference between pre and post values was compared using pared t-test. RESULTS: As a result of vital capacity measurements, there was no significant difference between FEV1 and FVC for women over 65 years old (p>0.05). Young women in their 20s had no significant difference in FEV1 (p>0.05), and FVC had significant differences (p<0.05). In measuring foot pressure to measure balance, both women aged 65 and above and young women in their 20s had a significant decrease in anterior foot pressure, and a significant increase in posterior foot pressure (p<0.05). CONCLUSION: The results of this study did not positively affect the vital capacity of elderly women with FHP. However, the significant increase in vital capacity of young women in their 20s suggests that contraction of the abdominal muscle is necessary during forced expiration. Therefore, it is believed that proper application and therapeutic interventions should be combined when applying Figure-8 brace.

The paper aims to provide a state-of-the-art review of methods for evaluating the effectiveness and effect of unloader knee braces on the knee joint and discuss their limitations and future directions. Unloader braces are prescribed as a non-pharmacological conservative treatment option for patients with medial knee osteoarthritis to provide relief in terms of pain reduction, returning to regular physical activities, and enhancing the quality of life. Methods used to evaluate and monitor the effectiveness of these devices on patients' health are categorized into three broad categories (perception-, biochemical-, and morphology-based), depending upon the process and tools used. The main focus of these methods is on the short-term clinical outcome (pain or unloading efficiency). There is a significant technical, research, and clinical literature gap in understanding the short- and long-term consequences of these braces on the tissues in the knee joint, including the cartilage and ligaments. Future research directions may complement existing methods with advanced quantitative imaging (morphological, biochemical, and molecular) and numerical simulation are discussed as they offer potential in assessing long-term and post-bracing effects on the knee joint.

STUDY DESIGN: This was a prospective cohort study.PURPOSE: This study aimed to evaluate the potential differences between the objective and subjective bracing compliances of adolescents with Scheuermann’s kyphosis.OVERVIEW OF LITERATURE: Bracing is a well-documented intervention for managing adolescents with progressive thoracic Scheuermann’s kyphosis, and the brace should be worn 23 hours every day. Most research studies that have investigated the efficacy of bracing have assumed that the patients wore the braces as advised or that the bracing time was measured subjectively. This may be one of the reasons for the conflicting reports regarding the efficacy of bracing.METHODS: Nineteen volunteers (11 girls and 7 boys, 12.89±1.77 years) who were prescribed Milwaukee braces for Scheuermann’s kyphosis were enrolled. Each brace was equipped with a miniature temperature logger to record the actual brace wearing time over a period of 3 weeks. The patients and their families were unaware of the mounted sensor. Each participants and/or parent was provided with a questionnaire to record the number of hours for which the brace was worn each day. In addition, the therapist asked each patient and/or his/her parent about the average number of hours that the brace was worn.RESULTS: The compliance rates measured using the temperature logger (16.00±4.90 hours daily) were significantly lower than those reported in the questionnaires (19.52±6.04 hours daily, p<0.001) and the verbal responses (20.21±6.05 hours daily, p<0.001). Moreover, there was no correlation of age, sex, and body mass index with brace compliance.CONCLUSIONS: The braces were worn less often than reported by the patients and/or their parents. Therefore, objective compliance assessments of adolescents with Scheuermann’s kyphosis in a brace are recommended for future studies.
