Association Between Scapular Posture and Two Different Pectoralis Minor Length Tests in Adolescents

Leyla Eraslan, Gulcan Harput, Damla Deniz, Taha Yildiz, Burak Ulusoy, Serdar Demirci, Dilara Kara, Elif Turgut, Irem Duzgun, Volga Bayrakci Tunay, and Nevin Ergun

Postural asymmetry due to the alterations in scapular posture is typically considered to be associated with injury. Pectoralis minor (PM) has played a crucial role in scapular posture, but limited knowledge exists that shows the possible effect of PM length on static scapular positioning in adolescents. The aim of this study was to investigate the association between static scapular positioning and two different PM length measurements in adolescents. Pearson rank test demonstrated that direct measurements of the PM length significantly and strongly inversely correlated to scapular anterior tilting (p = .01; r = −.592)and significantly and moderately inversely correlated to scapular internal rotation (p = .013; r = −.465) and scapular downward rotation (p = .028; r = −.416). However, indirect measurement of the PM length was not related to scapular posture. No significant correlation was found between direct and indirect PM length measurements. Direct measurement of PM length presents more information regarding alterations of the static scapular positioning.

Return to Play for Exertional Rhabdomyolysis in Korea National Rugby Player

Jaehong Kim, Jeung Yeol Jeong, and Daeho Kim,

This case report describes the process of returning to play as a case of exertional rhabdomyolysis caused by excessive training by a national rugby player. The authors reported the serum analysis, urinalysis, visual analog scale for pain, and lower-extremity functional scale. The aspartate aminotransferase, alanine transaminase, and myoglobin levels in the serum analysis decreased normally during the eighth day, and creatine phosphokinase levels decreased to normal levels by the 15th day. The maximal scale of visual analog scale for pain was 10 from the third day to the fifth day, and gradually decreased from the sixth day (scale = 6.6) to the 13th day (scale = 0.9). The lower-extremity functional scale scores after the diagnosis of exertional rhabdomyolysis were 0 at the third day, 47 at the 10th day, and 80 at the 24th day. A moderate increase in water intake could help the player recover faster. To restore overall body condition for rugby performance, specific athletic therapy and training should be provided at a predetermined specific time.

Ankle Dorsiflexion Promotes Irradiation of Ipsilateral Quadriceps Musculature in a Healthy Population

Emily Lahne, Grace Golden, and Shelley W. Linens

Clinical Question: Does ankle dorsiflexion promote irradiation of ipsilateral lower extremity musculature during a maximal isometric quadriceps contraction task in a healthy population? Clinical Bottom Line: There is preliminary evidence supporting the use of active ankle dorsiflexion during isometric quadriceps exercises to promote increased quadriceps activation and force production. As isometric quadriceps exercises are often included in initial stage rehabilitation, increasing muscle activation and force production may be beneficial.

Examination of Body Mass Changes Among Division I Collegiate Football Players With Sickle Cell Trait

Rebecca M. Hirschhorn, Jessica L. Phillips Gilbert, Danielle A. Cadet, Tenley E. Murphy, Clinton Haggard, Stephanie Rosehart, and Susan W. Yeargin

American football athletes are frequently hypohydrated before and during activity. Hypohydration increases the risk of exertional sickling in student-athletes with sickle cell trait (SCT). The authors examined weight charts from the 2010/2011 to 2018/2019 seasons at one Division I institution to determine if differences in percentage body mass losses (%BML) exist between those with and without SCT. Seventeen student-athletes with SCT and 17 matched-controls were included. A Bonferroni correction was applied to account for multiple comparisons (0.05/8), resulting in p < .006 considered significant. There was a significant difference for %BML between groups (SCT: 0.84 ± 0.65% vs. control: 1.21 ± 0.71%; p = .002) but not for the number of days %BML exceeded 2% (SCT: 0 ± 1 vs. control: 1 ± 1; p = .016). Implementation of proper hydration strategies minimized %BML in athletes with SCT, decreasing the risk of hypohydration and exertional sickling. The same strategies ensured all players remained below threshold to optimize performance and reduce heat illness risk.

Effect of Fatigue on Hip and Knee Joint Biomechanics in Anterior Cruciate Ligament Deficient Patients

Komeil Dashti Rostami and Abbey Thomas

The influence of fatigue on landing biomechanics in anterior cruciate ligament deficient (ACLD) patients is poorly understood. The purpose of this study was to examine the effect of fatigue on hip and knee joint biomechanics in deficient patients. Twelve ACLD males and 12 healthy control subjects participated in the study. The ACLD patients landed with increased peak knee flexion angle (F = 15.71, p < .01) and decreased peak knee flexion moment (F = 9.13, p < .01) after fatigue. Furthermore, ACLD patients experienced lower vertical ground reaction forces compared with controls regardless of fatigue state (F = 9.75, p < .01). It seems that ACLD patients use protective strategy in response to fatigue in order to prevent further injury in knee point.

The Effectiveness of a Psychoeducational Program in Increasing Mental Health Knowledge in Collegiate Athletes: A Critically Appraised Topic

Alexis Peters, Julliana Tapia, and Stephanie H. Clines

Focused Clinical Question: Does the implementation of a psychoeducational program increase mental health knowledge among collegiate student-athletes? Clinical Bottom Line: There is consistent, limited-quality patient-oriented evidence to suggest that implementation of a psychoeducational program is effective in increasing mental health knowledge in collegiate student-athletes based on the guidelines of the strength of recommendation taxonomy.

Exploring Workload Associated With Learning Foot Core Exercises

Katherine Newsham

Patients and clinicians have expressed frustration when learning or teaching intrinsic foot muscle exercises. However, there is limited information on how patients perceive the workload of an exercise. This study evaluates participants’ perceptions of workload while learning intrinsic foot muscle exercises with or without neuromuscular electrical stimulation. Twenty-six individuals completed a 4-week supervised intrinsic foot muscle training program. Thirteen participants utilized neuromuscular electrical stimulation during the initial 2 weeks of training. Participant perceptions of workload, measured by the National Aeronautics and Space Administration Task Load Index, revealed decreasing load over 2 weeks and minimal load at 4 weeks. Inclusion of neuromuscular electrical stimulation did not affect perception of load of skill acquisition.
