Is ankle taping effective to limit the ankle dorsiflexion in a single-training session? An observational study in semi-professional basketball players

ABSTRACT BACKGROUND: Ankle taping (AT) is effective in preventing ankle sprain injuries in most common sports and is employed in rehabilitation and prevention sports. OBJECTIVE: This study aimed to investigate the effectiveness of AT to restricting excessive frontal plane ankle movements in semi-professional basketball players throughout the training session. DESIGN AND SETTING: A cross-sectional study was performed at the Universidad Europea de Madrid. METHODS: Forty male and female semi-professional basketball players were divided into two groups. The ankle dorsiflexion range of motion (ROM) and interlimb asymmetries in a weight-bearing lunge position were evaluated at four time points: 1) with no tape, 2) before practice, at 30 min of practice, and 3) immediately after practice. RESULTS: In male basketball players, no differences were observed in the right and left ankles between the baseline and 30 min and between baseline and 90 min of assessment. In female athletes, significant differences were reported between baseline and pre-training assessments for the right ankle and also significant differences between baseline and 90 min in both ankles. CONCLUSIONS: Ankle taping effectively decreased the ankle dorsiflexion ROM in male and female basketball players immediately after application. However, ROM restriction was very low after 30 and 90 min, as assessed in a single basketball practice. Therefore, the classic taping method should be revised to develop new prophylactic approaches, such as the implementation of semi-rigid bracing techniques or the addition of active stripes during training or game pauses.

Exploring physical and functional factors associated with lateral ankle sprains in junior high school basketball players / 体力科学

Lateral ankle sprain (LAS) is one of the most common sport-related injuries among basketball players. Most basketball players experience a first LAS particularly in junior high school. Thus, it is crucial to develop effective prevention strategies for LAS in junior high school populations. However, the characteristics for first-time LAS are not clear. This study aimed to compare the physical and functional characteristics of junior high school basketball players with and without a history of LAS. Two hundred and thirty-eight junior high school basketball players (128 boys and 110 girls) volunteered for this study. We asked participants to complete a self-reported injury history questionnaire. We also assessed physical functions, including range of motion, muscular strength, dynamic balance, and performance. The prevalence of LAS was 75.6% (boys: 73.4%, girls: 78.2%). Boys with a history of LAS had significantly higher height, body mass, and BMI compared to those without a history of LAS (p<0.05). Girls with a history of LAS had significantly lower scores on the star excursion balance test in the anterior reaching direction compared with the control group (p=0.015). Various measures of physical function were associated with LAS, but these associations were different between boys’ and girls’ basketball players. These findings from this study indicate that clinicians should identify sex-specific impairments associated with LAS when designing targeted intervention programs.

Implementation of ottawa ankle rules in university hospital emergency room: pilot study / Implementação das regras de ottawa para tornozelo em pronto-socorro de hospital universitário: estudo piloto

ABSTRACT Ankle injuries are the most common musculoskeletal injuries in emergency rooms and are associated with a great social and economic impact. The need to request additional tests for ankle sprains is based on suspicion of fracture. The Ottawa Ankle Rules (OAR) establish criteria for ordering radiographs to avoid performing unnecessary examinations. Objective: To evaluate the implementation of the Ottawa Rules as a protocol for treating ankle sprains in the emergency department of a university hospital. Methods: This is a retrospective observational study, conducted over a period of three months before and three months after implementation of the protocol. Results: In the first phase, all patients complaining of ankle sprain underwent radiographs. In the second phase, after the application of the OAR, out of 85 patients evaluated, only 58 underwent complementary exams, showing a reduction of 31.8% in the request for imaging exams. There was no significant difference in fracture detection between the two groups (p=0.476). Conclusion: The OAR can be used as a tool in diagnosing ankle sprains, and their implementation reduced the request for imaging exams. Level of Evidence III, Retrospective Comparative Study.

Objective To quantify operation characteristics of the ankle rotating-traction-poking manipulation (RTPM) for treating acute lateral ankle sprain by using motion capture technology, so as to provide objective references for standardized operation of RTPM and its education inheritance. Methods A professional physiotherapist performed the RTPM on 60 volunteers with acute lateral ankle sprain. Motion capture system was used to acquire effective kinematic data during the RTPM, so as to make analysis and summarize rules. Results The average time of ankle rotating for six circles was 11.36 s and the average time of ankle traction and poking was 3.42 s. The average displacement of ankle traction was 36.94 mm and the average displacement of ankle poking was 22.44 mm. The average angle of ankle traction was 23.27°, and the average angle of ankle poking was 22.76°. During the RTPM for treating acute lateral ankle sprain, the average linear velocity of ankle rotating was 58.28 mm/s, and the average linear velocity of ankle traction and poking was 23.81 mm/s. The linear acceleration of ankle rotating was 0.43 mm/s2, and the linear acceleration of ankle traction and poking was 0.54 mm/s2. Conclusions The RTPM can be applied in clinical practice. During the RTMP, the principle of gentleness, rhythmicity and continuity should be followed. Under the premise of following physiological characteristics of ankle joint, treatment of the sprained ankle should be carried out with slow and uniform speed continuously.

Ankle and foot mechanics in individuals with chronic ankle instability during shod walking and barefoot walking: A cross-sectional study / 中华创伤杂志(英文版)

PURPOSE@#This study evaluated the angular kinematic and moment of the ankle and foot during shod walking and barefoot walking in individuals with unilateral chronic ankle instability (CAI).@*METHODS@#Recreational soccer players with unilateral CAI were recruited for this cross sectional study conducted between January and August 2019. A total of 40 participants were screened for eligibility but only 31 met the inclusion criteria based on the methods of Delahunt et al and Gribble et al. Except for 3 participants not attending the evaluation session, 28 participants were finally included. A three dimensional motion analysis system made up of ProReflex motion capture unit and an AMTIb Kistler force plate, embedded in the middle of nine meter walkway, were used to assess the ankle and foot angles and moment during shod walking and barefoot walking conditions. A Statistical Package for Social Sciences (version 20.0) was used to analyze data.@*RESULTS@#During shod walking, the ankle joint plantar-flexion range of motion (ROM) at 10% of the gait cycle (GC) and dorsiflexion ROM at 30% of the GC were significantly higher than those during barefoot walking for both feet (p = 0.001, 0.001, 0.027, and 0.036 respectively). The inversion ROM during shod walking was significantly higher than that during barefoot walking for both feet at 10% and 30% of the GC (p = 0.001. 0.001, 0.001, and 0.042 respectively). At 10% of the GC, the eversion moment was significantly higher between barefoot and shod walking for both feet (both p = 0.001). At 30% of the GC, there was no significant difference between shod and barefoot walking plantar-flexion moment of both feet (p = 0.975 and 0.763 respectively), and the eversion moment of both feet (p = 0.116 and 0.101 respectively).@*CONCLUSION@#At the early stance, shod walking increases the ankle plantar-flexion and foot inversion ROM, and decreases the eversion moment for both feet in subjects with unilateral CAI. Therefore, the foot wearing condition should be considered during evaluation of ankle and foot kinematics and kinetics.

Regenerative Medicine as a Potential and Future Intervention for Ankle Sprain

@#Ankle sprain is one of the most common injuries associated with physical activities. Complications including pain and ankle instability are associated with decreased physical activity, reduced sport performance, and increased risk of recurrent ankle injury leading to detrimental effect on activities of daily living. Current management of ankle sprain can be conservative or surgical for serious cases. However, long healing period is required for conservative management in addition to its side effects and the risk of post-operative complications for surgical management. Due to the current challenges and setbacks faced by existing intervention, this paper aims to generate ideas in incorporating regenerative medicine as an intervention for ankle sprain. This review will provide a brief review on the existing management for ankle sprain along with some history, application and the potential of regenerative medicine in speeding up the healing process of ankle sprains.

Biomechanics Characteristics and Its Correlation with Proprioception of Ankle Post Sprain / 中国康复理论与实践

Objective:To quantitatively evaluate the biomechanical properties and proprioception by comparing the range of motion (ROM), muscle strength, stiffness and proprioception of ankle joint in patients with ankle sprain, in order to provide therapeutic strategy for the patients with ankle sprain. Methods:From April to July, 2019, 21 patients with ankle sprain were included. The ROM and muscle strength of bilateral ankle joint were recorded, and the stiffness was evaluated by ankle joint training assistant system, at the end of dorsiflexion and plantarflexion, and plantarflexion 20°. The proprioception of ankle was quantitatively evaluated, including motion perception threshold (MPT) and passive position sense (PAPS). The ROM, muscle strength, joint stiffness, MPT and PAPS were compared, and the correlation among ROM, joint stiffness and proprioception were analyzed. Results:Compared with the unaffected side, the dorsiflexion and plantarflexion ROM decreased (|t| > 2.817, P < 0.05), the dorsiflexion and plantarflexion muscle strength decreased (|t| > 5.785, P < 0.01), the stiffness at the end of plantarflexion increased (t = 3.036, P = 0.007) in the affected side. However, there was no significant difference in stiffness at the end of dorsiflexion and dorsiflexion 20° between two sides (t < 0.874, P > 0.05), nor in MPT and PAPS (t < 0.695, P > 0.05). The plantarflexion ROM on the affected side was negatively correlated with the stiffness at the end of plantarflexion (r = -0.466, P < 0.05) and MPT (r = -0.613, P < 0.05), and MPT was positively correlated with the stiffness at the end of plantarflexion (r = 0.469, P < 0.05). Conclusion:The dorsiflexion and plantarflexion ROM and muscle strength decreased in the patients with ankle sprain, while the stiffness at the end of plantarflexion increased, which was related to proprioception. Quantitative measurements of ankle joint biomechanics and proprioception contributed to making ankle rehabilitation strategies. Rehabilitation after ankle sprain included training for ROM and muscle strength, and plantarflexion stretch to improve the plantarflexion stiffness, which may promote the recovery of proprioception and ankle function.

Acute Anterior Talofibular Ligament Open Type Avulsion Fracture: A Case Report / 대한족부족관절학회지

An ankle sprain is a relatively common sports-related injury but a severe open ankle sprain (SOAS) is very rare. A 27-year-old female athlete was injured during running and was hospitalized because of an inversed ankle injury with an open wound. She was diagnosed initially with an open-avulsion fracture at the tip of the fibula with an anterior talofibular ligament tear. The patient was finally diagnosed with SOAS from the surgical findings and literature review. SOAS should also be considered if there is a transverse open wound at the time of an ankle injury.

The Effect of a Proximal and Distal Tibiofibular Joint Manipulation on Dorsiflexion and Balance in Individuals with a History of Lateral Ankle Sprain

PURPOSE: This study aimed to evaluate the changes in dorsiflexion and balance following proximal and distal tibiofibular joint manipulation in individuals with a history of lateral ankle sprain (LAS). METHODS: Fifteen participants with a history of unilateral LAS, exhibiting a restriction in ankle dorsiflexion were included in this study. LAS ankle received a manipulation to the proximal and distal tibiofibular joint, while the opposite control ankle received no manipulation intervention. The outcome measures included ankle dorsiflexion and balance. Ankle dorsiflexion was measured using weight-bearing lunge test. Static and dynamic balances were measured using the overall, anterioposterior, and mediolateral balance index via the biodex balance system. Measurements were obtained prior to and following manipulation. RESULTS: This study showed that ankle dorsiflexion and dynamic balance were improved following the manipulation compared to those prior to the manipulation (p0.05). CONCLUSION: The joint manipulation technique applied to the ankle of those with a history of LAS appears to improve ankle dorsiflexion and dynamic balance. This suggest that a manipulation to the proximal and distal tibiofibular joint could be provided as preliminary data regarding the prophylactic effects of recurrent LAS.

Análise do COP e sentido de posição em jogadores universitários de futebol com e sem instabilidade de tornozelo / The analysis of COP and joint position sense in university soccer players with and without ankle instability

Resumo O objetivo do estudo foi comparar o comportamento do COP e do sentido de posição articular passivo em indivíduos com e sem instabilidade de tornozelo, e correlacionar as variáveis de COP e sentido de posição articular passivo. Participaram 20 indivíduos, divididos em dois grupos: grupo estável (GE) e grupo instável (GI). A avaliação do COP foi feita com o teste de apoio unipodal, com olhos abertos e fechados sobre uma plataforma de força. O teste de reposicionamento articular passivo foi realizado com os olhos vendados. O tornozelo foi posicionado em um ângulo alvo (10° e 20°) e o dinamômetro movia passivamente o tornozelo, então os participantes eram instruídos a apertar o botão para parar o movimento quando sentissem que o tornozelo estava no ângulo alvo, obtendo assim o erro angular absoluto (EAA). Foram obtidas as variáveis: deslocamento total (DT); desvio padrão ântero-posterior (DPap) e médio-lateral (DPml); velocidade média total (VMT); velocidade média ântero-posterior (VMap) e médio-lateral (VMml). A comparação entre dados que apresentaram distribuição normal foi feita com o teste t de Student, enquanto que para DT e DPml foi utilizado o teste de Mann-Whitney. Da mesma forma, foram usados os testes de Pearson e Spearman para correlacionar as variáveis. Foi adotado α < 0,05. Houve diferença entre EAA-10° (p < 0,05). Foram encontradas fortes correlações entre: EAA-10° e VMT (p < 0,01 r = −0,867); EAA-10° e VMap (p < 0,01 r = −0,854); EAA-10° e VMml (p < 0,01 r = −0,771), na condição olhos abertos, e EAA-10° e DT (p < 0,05 r = −0,666); EAA-10° e DPap (p < 0,05 r = −0,685) e EAA-10° e VMml (p < 0,05 r = −0,766) na condição olhos fechados. Entorses de tornozelo prejudicam o sentido de posição, sem afetar o equilíbrio.(AU)

Abstract The aim of the study was to compare the behavior of COP and passive ankle position sense in subjects with and without functional ankle instability. Took part in this study 20 subjects, divided into two groups: stable group (SG) and unstable group (UG). The COP evaluation was made with the single-leg balance test, with eyes opened and closed, on a force plate. The passive ankle position sense test was performed with subjects blindfolded. The ankle was positioned in a target angle (10° and 20°) and the dynamometer moved passively the ankle, then the subjects were instructed to push the stop button when they feel that the ankle was on the target angle, obtaining the absolute angular error (AAE). The following variables were obtained: total displacement (TD); antero-posterior (SDap) and medio-lateral standard deviation (SDml); total mean velocity (TMV); antero-posterior (MVap) and medio-lateral mean velocity (MVml). The comparison between the data with normal distribution was made with the Student's t test, while to the TD and SDml was used the Mann-Whitney test. The correlations were performed with the Pearson and Spearman tests. We adopted α < 0.05. We observed difference between AAE-10° (p < 0.05). Strong correlations were found between: AAE-10° and TMV (p < 0.01 r = −0.867); AAE-10° and MVap (p < 0.01 r = −0.854); AAE-10° and MVml (p < 0.01 r = −0.771), with eyes opened, and AAE-10° and TD (p < 0.05 r = −0.666); AAE-10° and SDap (p < 0.05 r = −0,685) and AAE-10° and MVml (p < 0.05 r= −0.766) with eyes closed. Ankle sprains harm the joint position sense without affecting the balance.(AU)

Mechanical characteristics of a semi-rigid ankle brace for protecting ankle varus / 医用生物力学

Objective To explore the mechanism of ankle sprain varus, a kind of human ankle brace with asymmetric physiological structure which can protect the ankle effectively is designed. Methods The anatomic factors of ankle varus were analyzed firstly, and a kind of ankle brace with asymmetric structure was designed based on asymmetric structure of ankle joint by anatomy. Using Kinect system and Geomagic Studio software, 3D scanning and digital modeling on ankle joint of a male adult were performed, and the ankle model was established by 3D printing technology. With EVA film, silica gel film and wrapped edge copper network as raw materials, two kinds of ankle brace with asymmetric structure were prepared by 3D draping and composite materials processing technology. The shaping properties, tensile properties, fatigue performance, outer fabric breathability and friction of the designed brace were tested. Results The outside of ankle brace with asymmetric structure had good shaping property, low tensile elastic recovery rate. Under the effect of repeated small load, EVA composite materials and silicone composite materials could keep good elastic recovery and effectively bear external varus forces. The results from air permeability and grinding test showed that polyester material was a kind of suitable fabrics for the outer lining material. Conclusions The mechanical properties of ankle brace with asymmetric structure can meet the requirement of ankle varus protection. The fabric of ankle brace can improve moisture permeability and frictional properties.

Misdiagnosis of Talar Body or Neck Fractures as Ankle Sprains in Low Energy Traumas

BACKGROUND: The talus has a very complex anatomical morphology and is mainly fractured by a major force caused by a fall or a traffic accident. Therefore, a talus fracture is not common. However, many recent reports have shown that minor injuries, such as sprains and slips during sports activities, can induce a talar fracture especially in the lateral or posterior process. Still, fractures to the main parts of the talus (neck and body) after ankle sprains have not been reported as occult fractures. METHODS: Of the total 102 cases from January 2005 to December 2012, 7 patients had confirmed cases of missed/delayed diagnosis of a talus body or neck fracture and were included in the study population. If available, medical records, X-rays, computed tomography scans, and magnetic resonance imaging of the confirmed cases were retrospectively reviewed and analyzed. RESULTS: In the 7-patient population, there were 3 talar neck fractures and 4 talar body fractures (coronal shearing type). The mechanisms of injuries were all low energy trauma episodes. The causes of the injuries included twisting of the ankle during climbing (n = 2), jumping to the ground from a 1-m high wall (n = 2), and twisting of the ankle during daily activities (n = 3). CONCLUSIONS: A talar body fracture and a talar neck fracture should be considered in the differential diagnosis of patients with acute and chronic ankle pain after a minor ankle injury.
