Point of Care Ultrasound Guided Management of Lateral Ankle Sprains: A Case Series.

Background: Lateral ankle sprain (LAS) is a common injury with incidence rates reported at 7.2 per 1000 person-years. Physical examination strategies provide limited information to guide rehabilitation that can maximize clinical outcomes. Early and accurate diagnostic information using ultrasound imaging enables individualized care and the ability to monitor healing along with its response to activity and rehabilitation. Purpose: The purpose of this study was to describe and observe the outcomes associated with Point of Care Ultrasound (POCUS) guided early management of acute and sub-acute lateral ankle sprains. Study Design: Case series. Methods: Individuals with a LAS within the prior 28 days underwent a clinical evaluation to include a POCUS exam to assess ligamentous integrity. Objective and POCUS findings were integrated to classify each LAS into one of four categories. Each grade of ankle sprain corresponded to levels of bracing for the protection of injured structures with each patient receiving physical therapy care based on rehabilitation guidelines. Participants completed the Foot and Ankle Ability Measure (FAAM) activities of daily living and Sports subscale, the Foot and Ankle Outcome Score (FAOS), Patient Reported Outcomes Measurement Information Systems Global Health, Tampa Scale of Kinesiophobia (TSK-11), Cumberland Ankle Instability Tool (CAIT), and the Numeric Pain Rating Scale as well as the Ankle Lunge Test and Figure 8 measurements at baseline, 4 weeks, 8 weeks and 12 weeks post enrollment. The FAAM Sport subscale, all FAOS subscales, and the TSK-11 were also collected at 24 weeks while the CAIT was collected at baseline and 24 weeks. Results: Fourteen participants were enrolled with 11 participants completing all data collection. FAAM Sport scores significantly improved at 4, 8, 12 and 24 weeks. All components of the FAOS significantly increased except for Sport scores at four weeks and Quality of Life scores at four and eight weeks. Conclusion: POCUS guided early management and ligamentous protection of LASs resulted in significant short and long-term improvement in function and return to sporting activity. This case series highlights the feasibility of using ultrasound imaging to assess the severity of ligamentous injury and align bracing strategies for ligamentous protection. The observations from this case series suggest that functional bracing strategies focused on ligamentous protection to promote healing and reduce re-injury rates does not delay improvement in functional outcomes. Level of Evidence: Level IV, Case Series.

Functional Syndesmotic Widening: A Case Report and Literature Review.

Injury to the distal tibiofibular syndesmosis can be a diagnostic challenge in the absence of advanced imaging. We report a case of a 21-year-old male patient who sustained an ankle injury and demonstrated radiological evidence of syndesmosis widening on plain radiographs. He underwent endobutton fixation which resulted in anterior subluxation of the talus and difficulty in ankle dorsiflexion. This is the first case report in the literature of a functional syndesmotic widening and the subsequent sequelae when subjected to a stabilisation procedure. The previously reported risk factors were inconsistent with our patient's demographics of a young, previously obese adult. We postulate that his childhood morbid obesity likely contributed to the functional widening of his ankle syndesmosis.

Validity and Reliability of the Timed 360° Turn Test in Individuals with Ankle Sprain.

Background: The Timed 360° turn test (T-360° TT) was developed to assess balance and turning ability. Although validity and reliability have been performed in different diseases, validity and reliability have not been performed in individuals with ankle sprain (AS). Purpose: The purpose of this study was to investigate the validity and reliability of the T-360° TT in individuals with AS. Methods: The study included 54 individuals with AS. Participants were initially evaluated with T-360° TT, Timed Up and Go (TUG) test and Biodex Balance System (BBS). To assess test-retest reliability, the T-360° TT was performed again 5 days after the first measurement by the same assessor. Results: At the end of the study, strong positive correlations were found between T-360° TT with TUG test and BBS (p < 0.05). In addition, T-360° TT had excellent test-retest reliability (Intraclass correlation coefficient = 0.87). Conclusion: The T-360° TT is a valid and reliable tool for the evaluation of balance and turning ability in individuals with AS. We also think that it can be used practically in clinical settings because it is a test that can be easily and quickly performed.

Low Back Pain Caused by Traction Peripheral Neuropathy Due to Chronic Ankle Instability: Three Clinical Cases.

Non-specific low back pain without identifiable causes on imaging is a common and frustrating problem for both patients and physicians. While proximal symptoms such as shoulder pain from distal upper extremity neuropathies such as carpal tunnel syndrome are well-known, peripheral neuropathy of the foot or ankle is rarely considered in the differential diagnosis for low back pain. This study aims to highlight the potential link between chronic ankle instability (CAI) and low back pain. We present three cases: a 32-year-old woman with chronic low back pain for over 10 years, a 59-year-old woman with transient low back pain after long drives, and a 42-year-old woman with acute low back pain while gardening. All patients had normal imaging studies but exhibited CAI on examination. Diagnostic modalities included the ankle anterior drawer test, application of ankle brace, superficial peroneal nerve (SPN) blocks, and assessment of the active straight leg raise (aSLR) angle. In the first case, low back pain disappeared after SPN neurolysis and ankle ligament reconstruction. The second case showed significant improvement in aSLR and pain reduction with SPN block and ankle brace. The third case experienced substantial pain relief with the use of an ankle brace. These findings suggest that addressing ankle instability and associated traction neuropathy can significantly alleviate low back pain symptoms. CAI may be an underrecognized cause of non-specific low back pain. Interventions such as ankle brace, SPN blocks, SPN decompression, and ankle ligament reconstruction can be effective for diagnosis and treatment, potentially offering relief for patients with chronic low back pain.

Noninstrumented Clinical Assessment of Static Postural Stability in Chronic Ankle Instability: A Systematic Review and Meta-Analysis.

CONTEXT: Several clinical tests are available to assess static postural stability in individuals with chronic ankle instability (CAI); however, it is unclear which test should be used. OBJECTIVE: To determine which noninstrumented clinical tests should be used to detect static postural stability deficits in individuals with CAI. EVIDENCE ACQUISITION: We searched 4 databases from their inception to February 2023, and included studies comparing static postural stability in individuals with CAI and healthy controls using noninstrumented assessments. Two reviewers independently extracted study characteristics, participant information, static postural stability assessment methods, and results. We calculated the pooled standardized mean difference (SMD) and 95% confidence interval using a random effects meta-analysis and assessed the certainty of the evidence. EVIDENCE SYNTHESIS: Fourteen cross-sectional studies (293 participants with CAI and 284 healthy controls) were included. The meta-analysis showed no significant differences between the CAI and healthy groups in the double-leg stance condition of the Balance Error Scoring System (BESS) (SMD, -0.03; low-certainty evidence). Significant group differences were found in the BESS single-leg stance (SLS) on firm and foam surfaces (SLS firm: SMD, 0.47, very low-certainty evidence; SLS foam: SMD, 0.80, very low-certainty evidence), the tandem stance (TS) on firm and foam surfaces (TS firm: SMD, 0.39, low-certainty evidence; TS foam: SMD, 0.76, low-certainty evidence), and the total BESS in the foam conditions (SMD, 1.12, very low certainty evidence). Significant differences were also found between the CAI and healthy groups in the foot-lift (SMD, 1.24; very low certainty evidence) and time-in-balance tests (SMD, -0.94; very low certainty evidence). CONCLUSIONS: Due to the large magnitude of the differences, the SLS foam, TS foam, and the total BESS in the foam conditions, as well as the foot-lift test or time-in-balance test, may be the most appropriate to clinically identify static postural stability impairment in individuals with CAI.

Gait Training Interventions for Individuals with Chronic Ankle Instability: A Systematic Review & Meta-Analysis.

OBJECTIVE: This review aimed to determine if gait training interventions influence lower extremity biomechanics during walking in individuals with chronic ankle instability (CAI). METHODS: A literature search was conducted in PubMed, CINAHL, SPORTDiscus, and MEDLINE to identify English-language studies from inception through September 2022. Eligible studies included randomized control trials, repeated measures design, and descriptive laboratory studies measuring the effects during or following a gait training intervention on biomechanical outcomes (kinematics, kinetics, electromyography) during walking in individuals with CAI. Gait training interventions were broadly categorized into devices (destabilization devices, novel gait training device) and biofeedback (visual, auditory, and haptic delivery modes). Meta-analyses were conducted when appropriate using random-effects to compare pre-and post- gait training intervention mean differences and standard deviations. RESULTS: Thirteen studies were included. Meta-analyses were conducted for single session gait training studies only. Eleven studies reported kinetic outcomes. Our meta-analyses showed location of center of pressure (COP) was shifted medially from 0-90% (Effect Size [ES] range=0.35-0.82) of stance, contact time was decreased in medial forefoot (ES=0.43), peak pressure was decreased for lateral midfoot (ES=1.18) and increased for hallux (ES=0.59), pressure time integral was decreased for lateral heel (ES=0.33) and lateral midfoot (ES=1.22) and increased for hallux (ES=0.63). Three studies reported kinematic outcomes. Seven studies reported electromyography outcomes. Our meta-analyses revealed increased activity following initial contact (IC) for fibularis longus (ES=0.83). CONCLUSIONS: Gait training protocols improved some lower extremity biomechanical outcomes in individuals with CAI. Plantar pressure outcome measures seem to be most impacted by gait training programs with improvements in decreasing lateral pressure associated with increased risk for lateral ankle sprains. Gait training increased EMG activity post-IC for the fibularis longus. Few studies have assessed the impact of multi-session gait training on biomechanical outcome measures. Targeted gait trainning should be considered when treating patients with CAI.

Correlations of Postural Stability to Proprioception, Tactile Sensation, and Strength Among People With Chronic Ankle Instability.

OBJECTIVES: The static and dynamic correlations of postural stability to its three potential contributors, namely, proprioception, tactile sensation, and strength remain unclear among people with chronic ankle instability (CAI). This study aimed to compare static and dynamic postural stability, along with proprioception, tactile sensation, and strength between people with and without CAI and explore their correlations. METHODS: Sixty-seven participants with CAI and 67 participants without CAI were enrolled in this study. Ankle proprioception, plantar tactile sensation, and lower limb strength were measured by a proprioception test device, a set of monofilaments, and a strength testing system, respectively. Static and dynamic postural stability were measured during standing and jump landing on a force plate and indicated by the root mean square of center of pressure and time to stability. RESULTS: Compared to people without CAI, people with CAI had poorer postural stability, proprioception, tactile sensation, and strength. Both groups demonstrated correlation between proprioception and static postural stability, but only people without CAI showed correlation between proprioception and dynamic postural stability. Both groups demonstrated a correlation between tactile sensation and static postural stability, but not with dynamic stability. Both groups demonstrated a correlation between strength and both static and dynamic postural stability. CONCLUSIONS: People with CAI had deficits in static and dynamic postural stability, proprioception, tactile sensation, and strength. Among people with CAI, proprioception, tactile sensation, and strength can help maintain static postural stability; strength can help maintain dynamic postural stability, whereas proprioception may not provide sufficient information for dynamic postural stability.

Comparison of an Adaptive Ankle Brace to Conventional Taping for Rehabilitation of Acute Ankle Injury in Young Subelite Soccer Players: A Pilot Study.

CONTEXT: Ankle sprains are a common injury in sports, for which use of external ankle support during rehabilitation has been suggested to improve clinical outcomes. DESIGN: Cohort study. METHODS: Thirteen soccer players experiencing acute lateral ankle sprain injury were provided a novel adaptive ankle brace or conventional ankle taping (control) as external ankle support throughout the injury rehabilitation process. All other clinical procedures were identical, and rehabilitation was supervised by the same team staff member. Time from injury to clearance to return to sport was tracked. Player experience with the ankle brace also was queried via electronic surveys. RESULTS: The median time to return to sport was less for the Brace group (52.5 d) compared to the Control group (79.5 d), but the distributions of the 2 groups were not found to differ significantly (P = .109). Player surveys indicated they felt the brace to be comfortable or very comfortable, with better freedom of movement than other braces and the same freedom of movement as wearing no brace. All players reported wearing the brace to be the same or better experience as ankle taping. DISCUSSION: These preliminary results indicate that the adaptive ankle brace is at least as effective as ankle taping for providing external support during the rehabilitation phase following acute lateral ankle sprain and suggest it may be a more effective ankle support solution in terms of patient compliance than conventional bracing or taping.

Immediate Effects of Wearing an Ankle Bandage on Fine Coordination, Proprioception, Balance and Gait in the Subacute Phase of Ankle Sprains.

Ankle sprains are the most frequently occurring musculoskeletal injuries among recreational athletes. Ankle support through bandages following the initial orthotic treatment might be beneficial for rehabilitation purposes. However, the literature is sparse regarding the use of an ankle support directly after the acute phase of an ankle sprain. Therefore, this study investigates the hypothesis that wearing an ankle bandage immediately after an acute ankle sprain improves motor performance, stability and reduces pain. In total, 70 subjects with acute unilateral supination trauma were tested. Subjects were tested five weeks post-injury to assess immediate effects of the ankle bandage. On the testing day, subjects completed rating questionnaires and underwent comprehensive biomechanical assessments. Biomechanical investigations included fine coordination and proprioception tests, single leg stances, the Y-Balance test, and gait analysis. All biomechanical investigations were conducted for the subject's injured leg with and without a bandage (MalleoTrain® Bauerfeind AG, Zeulenroda-Triebes, Germany) and the healthy leg. Results indicated moderate to strong improvements in ankle stability and pain relief while wearing the bandage. Wearing the bandage significantly normalized single leg stance performance (p < 0.001), stance phase duration (p < 0.001), and vertical ground reaction forces during walking (p < 0.05). However, the bandage did not have a clear effect on fine coordination and proprioception. The findings of our study suggest that ankle bandages may play a crucial role in early-stage rehabilitation by enhancing motor performance and reducing pain.

Validity and reproducibility of the ARL-RSI score to assess psychological readiness before returning to sport after lateral ankle sprain.

Purpose: Although multiple scales exist to evaluate psychological readiness before returning to sport post-lateral ankle sprain (LAS), no score has been validated specifically for LAS or chronic ankle instability. The main aim of the study is to evaluate the validity and reproducibility of the ankle ligament reconstruction-return to sport injury (ALR-RSI) scale in assessing psychological readiness after LAS and its ability to identify patients who can return to their preinjury level. Methods: A total of 64 patients (35 females and 29 males; 33.8 ± 13.2 years) who recently experienced an acute LAS were included in this study. All patients participated in a predictive validation component of the study and were assessed at 2 and 4 months following an LAS. The ALR-RSI was completed twice by 20 patients at a 7-day interval to evaluate the reliability of the score in patients suffering from LAS. Results: The ALR-RSI was significantly (p < 0.001) and positively correlated with the other scores. The correlation was strong with the Foot and Ankle Ability Measure Sports: r = 0.77; 95% confidence interval [CI]: 0.78-0.83) and moderate with the American Orthopaedic Foot and Ankle Society (r = 0.69; 95% CI: 0.60-0.78) and the Foot and Ankle Ability Measure Activities of Daily Living Scores (r = 0.63; 95% CI: 0.51-0.72). Two-month ALR-RSI scores had good ability for predicting nonreturners at 4 months (area under the curve = 0.76; 95% CI: 0.6-0.9; p = 0.005). A Youden index of 0.51 was observed at an ALR-RSI score of 46%, corresponding to a sensitivity of 67% and specificity of 83%. Test-retest reliability of the ALR-RSI was excellent, with an ICC of 0.98 (95% CI: 0.96-0.99), a standard error of measurement of 3.02% and a minimum detectable change of 8.37%. Conclusions: The results of the current study validated the ALR-RSI as an important questionnaire to assess psychological readiness to return to sport after LAS. Level of Evidence: Level II prospective cohort study.

Effect of aquatic versus conventional physical therapy program on ankle sprain grade III in elite athletes: randomized controlled trial.

INTRODUCTION: Ankle sprains are the second most common sports injury after knee injuries, with about 85% of them affecting the lateral ankle ligaments. These injuries are particularly prevalent in sports like basketball and volleyball. PURPOSE: To investigate the effect of Aquatic therapy as an early rehabilitation protocol for elite athletes with acute lateral ankle sprain grade III on back-to-sport time, dynamic balance, pain, Athletic performance, and muscle power compared to land-based exercise training. METHODS: Thirty elite athletes have ankle sprain grade III with sprain onset from 1 to 7 days, their age ranges from 18-30 years old were recruited. All participants are professional athletes; mainly participating in above-head sports such as volleyball and basketball. The patients were randomly allocated into two treatment groups: Group I (control group): 15 patients received a conventional physical therapy program of structured therapeutic exercise program, manual therapy and land-based exercises, in addition to external support, and Group II (Aquatic therapy group): 15 patients received aquatic training. Visual Analog Scale (VAS) was used to measure the pain intensity, while the dynamic balance was measured by the Star Excursion Balance Test. Athletic performance was measured by HOP Tests (Single, Triple, 6-m, and Cross-over hops) aided by the Agility T-Test (ATT) and Illinois Agility Test (IAT). Muscle power was tested by a Single Leg Press. Finally, back to sports time was recorded for each participant in both groups. RESULTS: There was a significant interaction effect of Aquatic therapy and time for VAS (p < 0.001), single hop (p < 0.001), triple hop (p < 0.001), cross-over hop (p < 0.001), IAT (p = 0.019) and ATT (p < 0.001) of both affected and nonaffected. There was no significant interaction effect of Aquatic therapy and time for 6-MHT of affected (p = 0.923), and nonaffected (p = 0.140). There was a significant main effect of time for all dependent variables (p < 0.001) except for 6-MHT of affected (p = 0.939), nonaffected (p = 0.109), and IAT (p = 0.099). The Star excursion dynamic balance test (SEBT) and Single leg press revealed a significant difference between groups on affected and non-affected sides (p < 0.001*). Lastly and most importantly the back-to-sport time revealed a significant difference in the return-to-sport time in favor of the Aquatic therapy group who returned faster than the control group (p < 0.001*). CONCLUSION: Aquatic therapy is more effective than traditional protocols regarding early rehabilitation of acute ankle sprain grade III in Elite professional athletes for reducing pain intensity, improving dynamic balance and athletic performance and power and accelerating their return to sports time. Because aquatic therapy produces better outcomes, it is advised to be included in the rehabilitation programs of athletic patients with acute ankle sprains grade III.

The Effects of Motor Imagery on Static and Dynamic Balance and on the Fear of Re-Injury in Professional Football Players with Grade II Ankle Sprains.

Lateral ankle sprains are one of the most frequent athletic injuries in football, causing deficits in balance. Motor Imagery (MI) has been successively included in sports rehabilitation as a complementary therapeutic intervention. The aim of the present study was to explore the effects of MI on static and dynamic balance and on the fear of re-injury in professional football players with Grade II ankle sprains. Fifty-eight participants were randomly allocated into two groups: First-MI group (n = 29) and second-Placebo group (n = 29), and they each received six intervention sessions. The first MI group received MI guidance in addition to the balance training program, while the second Placebo group received only relaxation guidance. One-way ANOVA showed statistically significant results for all variables, both before and 4 weeks after the interventions for both groups. The t-test showed statistically significant differences between the two groups for static balance for the right lower extremity (t = 3.25, S (two-tailed) = 0.002, p < 0.05) and also for heart rate (final value) in all time phases. Further research is needed in order to establish MI interventions in sports trauma recovery using stronger MI treatments in combination with psychophysiological factors associated with sports rehabilitation.

Epidemiology of lateral ankle sprain focusing on indirect contact mechanism in male and female soccer players: An 18.5-month cohort study.

BACKGROUND: Epidemiological research highlights the need to understand sports injuries for effective prevention. Yet, detailed knowledge about lateral ankle sprain (LAS) in soccer, especially related to indirect contact mechanisms and specific sports movements, remains scarce. This study aimed to determine the prevalence of LAS by examining injury mechanisms, focusing on indirect contact, and analyzing sports-related movements. STUDY DESIGN: Prospective study. METHODS: In this prospective study, 304 high-school and college soccer players (age: 19.0 ± 2.2 years, height: 168.3 ± 10.6 cm, weight: 64.2 ± 11.1 kg) were monitored for 18.5 months. Attendance and LAS incidents were recorded daily. Injury details, including movement at the time of injury, contact presence, and direction, were collected through interviews conducted on the injury day. LAS were categorized into direct contact, indirect contact, and non-contact mechanisms. Direct contact injuries were due to external forces on the lower leg or foot. Indirect contact injuries resulted from impacts on areas other than the lower leg or foot, and non-contact injuries involved no interaction with the ball or opponent. Incidence rates per 1,000 athlete exposures and 95 % confidence intervals (CIs) were calculated, along with rate ratios (RR) to assess sex differences. RESULTS: The study recorded 59 LAS injuries. Indirect injuries were predominant, accounting for 47.5 % (n = 28) of the cases. Men experienced a higher incidence of indirect injuries, with an RR of 2.29 (95 % CI: 1.06-4.96). Outward contact was the most common (77.8 %; n = 21), while inward contact occurred in 22.2 % of the cases (n = 6). CONCLUSION: High school and college soccer players primarily sustained injuries through indirect contact mechanisms, with a significant number of injuries occurring during lateral contact. Men were more prone to indirect contact injuries. Furthermore, 47.5 % of LAS incidents involved reactive movements, and injuries frequently occurred during specific sports actions, such as ball interception.

Single-legged landing behavior of high school basketball players with chronic ankle instability.

OBJECTIVES: Anterior cruciate ligament injury is one of the most serious ligamentous injuries. The purpose is to compare the impact of the ankle joint on the knee during landing between athletes with chronic instability and a control group (coper group) and to verify the effects of the kinetic chain from other joints. DESIGN: Prospective study. SETTING: High school basketball. PARTICIPANTS: Participants were 62 female high school basketball players who had participated in team sports for >6 months. MAIN OUTCOME MEASURES: Player joint angles, movements, and moments. RESULTS: The knee valgus moment was significantly higher in the chronic ankle instability group than in the coper group (20%-60% [p < 0.01]; 80%-100% [p < 0.05]) during landing motion. The knee valgus moment was also significantly higher during the change from the maximum knee joint flexion position to the maximum extension (p < 0.05). In addition, the landing motions of the chronic instability group may have utilized suboptimal compensatory motor strategy on the sagittal plane, depending heavily on the knee joint's abduction moment. CONCLUSIONS: Our findings indicate that the chronic ankle instability group uses a different landing strategy pattern than the coper group by changing the joint moment and joint angle during landing, which may increase the risk of anterior cruciate ligament injury.

A Case Report of Isolated Cervical Ligament Rupture With Hyper-Pronation Injury: Specific MRI Protocol and Surgical Reconstruction.

Background: The aim of this case report is to present a case of chronic cervical ligament tear and instability, which occurred by an unusual work injury with an eversion/hyper-pronation mechanism in contrast to the usual mechanism of inversion. The ligament was reconstructed using an allograft with satisfactory results up to 30 months after surgery. A new magnetic resonance imaging protocol (MRI) was developed to better evaluate the cervical ligament/graft. Conclusion: In diagnosis of foot sprains, a specific ligament injury should always be sought. In this case, physical examination producing tenderness at the location of the cervical ligament and correlating this with an oblique intercolumn stress test that reproduced pain with apprehension and gross instability supported the diagnosis. Retrospectively applying anatomic knowledge to the earlier MRI findings of bone marrow edema at the insertion points of the cervical ligament on the talus and calcaneus was important in confirming the diagnosis. To better evaluate the cervical ligament allograft tendon reconstruction, a novel volumetric MRI sequence was developed which may prove helpful to also diagnose cervical ligament injuries in future cases. Anatomic reconstruction of the cervical ligament provided satisfactory clinical and radiographic results at 30-month follow-up.Level of Evidence: V.

Immediate Efficacy of Contralateral Acupuncture on SI3 Combined with Active Exercise for Acute Lumbar Sprains: Protocol for a Randomized Controlled Trial.

Purpose: Acute lumbar sprain (ALS) is a common clinical disease characterized by persistent intolerable low back pain and limitation of movement, and quick pain relief and restoration of mobility in a short time are the main needs of patients when they visit the clinic. This study aims to evaluate the immediate efficacy of contralateral acupuncture (CAT) on SI3 combined with active exercise in treating ALS. Methods and Analysis: This study is a randomized controlled trial which will recruit 118 eligible participants aged 18 to 55 years with ALS at the Second Affiliated Hospital of Yunnan University of Chinese Medicine between March 2024 and December 2026. Participants will be randomly assigned to the acupuncture group or the sham-acupuncture group in a 1:1 ratio. The acupuncture group will receive a 10-minute acupuncture treatment combined with active exercise, while the sham-acupuncture group will receive a 10-minute sham acupuncture treatment combined with active exercise. Randomization will use a computer-generated sequence with allocation concealed in opaque envelopes. The primary outcome will be the pain visual analogue scale (VAS) scores after 10 minutes of treatment. Secondary outcomes will include the pain VAS scores at other time points (2, 4, 6, and 8 minutes post-treatment), the lumbar range of motion (ROM) scores at various time points, blinded assessment, the treatment effect expectancy scale, and the rescue analgesia rate. The analysis will follow the intention-to-treat principle. The primary outcome will be analyzed using ANCOVA, and secondary outcomes with repeated measures ANOVA. The rescue analgesia rate will be assessed using either the χ2 test or Fisher's exact test. Discussion: This study is the first randomized controlled trial to assess the immediate efficacy of CAT in combination with active exercise for ALS. This study will provide a simple, rapid, and effective treatment for the clinical management of ALS.

Effect of Sex and Lateral Ankle Sprain History on Dorsiflexion Range Of Motion Asymmetry During the Weight Bearing Lunge Test.

Background: Reduced dorsiflexion range of motion (DFROM) which is commonly seen following lateral ankle sprain (LAS) has the potential to influence lower extremity biomechanics which have been linked to increased injury risk in the female athlete. Current research on the effect of sex and LAS history on DFROM is limited. Hypothesis/Purpose: This study had three aims 1) to determine the effect of sex, leg dominance and LAS history on DFROM, 2) to determine the effect of sex and LAS history on magnitude of DFROM symmetry and 3) to examine the association of sex on direction (whether dominant or non-dominant limb had the higher DFROM) of symmetry. Study Design: Cross-Sectional Study. Methods: DFROM was measured bilaterally in 105 recreational athletes all participating in multidirectional sports using the tape measurement method during the weight bearing lunge test (WBLT). A mean of three measurements was used for analysis. A 3-way mixed ANOVA was carried out to determine the interaction between sex, LAS history and leg dominance on DFROM and a 2-way ANOVA for the effect of sex and LAS history on asymmetry. A chi-square test was used to determine the association of sex and direction of asymmetry. Results: The results indicate no significant effect of sex, LAS history, and leg dominance on DFROM (p=0.65). Main effects were significant for sex and LAS on DFROM. The mean asymmetry for all participants was reported as 12.25±14.76cm. No significant effect of sex and LAS history on magnitude of asymmetry was reported. There was a significant association of sex and direction of asymmetry (χ2(1) = 11.26, p = 0.00). Sixty-five-point two percent of males were shown to have higher DFROM of their non-dominant limb compared to 75% of females who were higher in their dominant limb. Conclusion: Findings from this study suggest that DFROM is affected by sex and LAS history. While females have increased DFROM compared to males, those with LAS history are more likely to have a decreased DFROM on the involved side. The results also indicate that interlimb asymmetries in DFROM are present in athletes, therefore practitioners should exercise caution when using bilateral comparisons in injury and return to play assessments.

Distal Tibiofibular Syndesmosis Injuries in the National Football League (NFL): A Spectrum of Pathology That Correlates With Time to Return to Full Participation.

BACKGROUND: Studies routinely evaluate high ankle sprains in isolation, but recent data suggest that these injuries are often associated with concomitant pathology, potentially influencing return to full participation. HYPOTHESIS: In National Football League (NFL) players, isolated high ankle sprains are rare and syndesmosis injuries with concomitant pathology will result in increased time to return to full participation. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: Distal tibiofibular syndesmosis injuries sustained by NFL players between 2017 and 2019 were identified through NFL Injury Surveillance Database queries and verified with video analysis. Each injury underwent a comprehensive magnetic resonance imaging (MRI) review. Regression modeling was utilized to explore the influence of numerous imaging findings on time to return to full participation. RESULTS: There were 83 external rotation ankle injuries involving the syndesmosis. Isolated distal tibiofibular syndesmosis injuries were rare (n = 11; 13%) and more often associated with other ligamentous injury (deltoid ligament and lateral ligamentous complex) and/or fractures. Regression modeling resulted in clustering of 3 injury pattern groups for time to return to full participation across numerous imaging findings: syndesmosis injury-fracture combinations (250 days [interquartile range [IQR,] 142-266 days]), syndesmosis injury with complete deep deltoid tear or acute diastasis (175 days [IQR, 20-248 days]), and all other syndesmosis injuries (27 days [IQR, 18-46 days]). CONCLUSION: In NFL athletes with external rotation ankle injuries, isolated distal tibiofibular syndesmosis injuries were rare and more often associated with concomitant pathology. Time to return to full participation was affected by an associated fracture and complete deep deltoid ligament tear or diastasis but no other relevant MRI variables such as lateral ligament complex involvement or the presence of osteochondral lesions or bone contusions.

Management of High Ankle Sprains Utilizing the Tightrope Surgical Procedure - A Novel Approach for a Rapid Return to Play.

The distal tibiofibular joint is described as a syndesmosis. The syndesmosis is important to the structural integrity of the ankle joint by maintaining the proximity of the tibia, fibula, and talus. Syndesmotic or high ankle sprains, involving the syndesmotic ligaments, pose a significant rehabilitative challenge due to their intricate anatomy, prolonged recovery periods following injury, and high susceptibility to persistent disability. Traditional management strategies have often been conservative, marked by lengthy periods of immobilization and a gradual return to activity. Severe syndesmotic injuries with diastasis have been treated surgically with screw fixation which may require a second intervention to remove the hardware and carries an inherent risk of breaking the screw during rehabilitation. Another fixation technique, the Tightrope™, has gained popularity in treating ankle syndesmosis injuries. The TightRope™ involves inserting Fiberwire® through the tibia and fibula, which allows for stabilization of the ankle mortise and normal range of motion. The accelerated rehabilitation protocol promotes early weight-bearing and has been shown to expedite the return to sport. This emerging strategy has shown promise in reducing recovery time as it is now possible to return to sport in less than 2 months after a tightrope repair and accelerated rehabilitation, compared with 3-6 months post screw fixation. This clinical commentary delves into this novel approach, highlighting the procedure, rehabilitation protocols, and the implications for physical therapy practice. Level of Evidence: V.

Ultrasound Imaging in Football Players with Previous Multiple Ankle Sprains: Keeping a Close Eye on Superior Ankle Retinaculum.

The superior extensor ankle retinaculum (SEAR), a transversely fascial thickening positioned above the tibia-talar joint, serves as a crucial anatomical structure in ankle stability. The purpose of this study was to measure and compare by ultrasound (US) imaging the bilateral thickness and echogenicity of SEAR in football players with previous multiple ankle sprains (group 1) and healthy volunteers (group 2). A cross-sectional study was performed using ultrasound imaging to measure longitudinal and transversal axes using a new protocol in a sample of 50 subjects: 25 football players with previous multiple ankle sprains and 25 healthy subjects. The findings for SEAR thickness revealed statistically significant differences for both axes (p = 0.0011 and p = 0.0032) between the healthy side and the previously sprained side, and with the corresponding side of group 2 (p = 0.003 and p = 0.004). Moreover, in group 1, regarding the ROI echogenicity, a statistically significant difference was found between the sides (p = 0.0378). These findings suggest that the football players with previous ankle sprains showed a thicker and inhomogeneous SEAR on the sprain side, unveiling a remodeling of this structure compared to the other side and to the healthy volunteers. In these athletes, during US examination, one needs to keep "a US eye" on side-to-side SEAR comparisons.
