Background: Given rising youth sport participation, 8 to 10-year-olds increasingly display comparable lower-extremity injury incidence to 11 to 17-year-olds and require effective return to sport criteria. One such criterion which quantifies dynamic stability is the Y-Balance Test (YBT), though it has not been validated in children under age 11.

Hypothesis/purpose: The purpose of this study was to examine the performance of 8 to 10-year-old patients on the YBT after lower-extremity injury and determine how these results compare to larger samples of age-grouped athletes within the validated 11 to 17-year-old range. It was hypothesized that 8 to 10-year-olds would display different normalized YBT distances compared to 11 to 17-year-olds.

Study design: Cross-sectional Study.

Methods: Patients (N=1093) aged 8 to 17 who presented to a pediatric sports medicine practice with a lower-extremity injury and completed the YBT between December 2015-May 2021 were included. Anterior, posteromedial, and posterolateral YBT scores were collected at return-to-sport for affected and unaffected limbs. Scores were normalized to limb length, and composite scores were created. Between-limb differences were calculated in groups of ages 8-10, 11-12, 13-14, and 15-17. Groups were also evaluated for differences by sex.

Results: A rise in performance was observed in unaffected limb anterior reach from ages 8 to 10 years to 11 to 12 years followed by a subsequent significant decrease at older ages (p<0.001). Affected limb anterior reach differed between the youngest group and two oldest groups (p=0.004). Anterior and composite difference were significantly different between the oldest three groups (p=0.014 anterior; p=0.024 composite). No differences were observed between sexes in 8 to 10-year-olds, though 11 to 12-year-old females reached further during all eight distances. In the older three groups, males generally displayed greater between-limb differences.

Conclusion: YBT scores, specifically anterior reach, demonstrated inconsistency by age and sex across a large adolescent cohort. Existing return-to-sport standards should not be used with younger athletes, and individual validation is required.

Background and purpose: Ulnar collateral ligament (UCL) injury is a common elbow injury among overhead athletes, particularly baseball pitchers. However, limited research exists for non-throwing athletes, especially regarding rehabilitation. The purpose of this case report is to illustrate the use of early weight-bearing activities into the rehabilitation protocol for non-operative management of athletes with a UCL injury.

Case description: The subject was a 17-year-old female competitive cheerleader. Two weeks prior, during the performance of an acrobatic skill in which she transitioned to full upper extremity (UE) weight-bearing, she sustained an injury to her right elbow. Physical therapy examination findings indicated a diagnosis of a UCL sprain. Self-reported outcome measures revealed a FOTO score of 69/100 and a Quick Dash score of 43/100. The subject attended 14 therapy sessions over nine weeks to address physical function and performance, which were assessed at intervals during her therapy program. Rehabilitation consisted of therapeutic exercise for the progression of UE functional weight-bearing including planks, ball push-ups, handstands, crab walks, stool pulls, handstand walks, and UE plyometric jumps.

Outcomes: Along with documented improvement of the standard musculoskeletal examination measures of range of motion, strength, and functional performance, the subject demonstrated no elbow instability and improved FOTO and Quick Dash scores of 98 and 0, respectively. The subject demonstrated 105% limb symmetry index with the return to sport (RTS) UE functional testing of one-armed seated shot-put throw (SSPT) and achieved normative values with the closed kinetic chain upper extremity stability test (CKCUEST).

Conclusion: This case report highlights the successful treatment of a subject with a UCL injury and the integration of therapy interventions with a focus on UE weight-bearing. Further research on performing high level UE weight-bearing activities during rehabilitation and RTS guidelines is needed.

Background: Pelvic floor dysfunction (PFD) occurs when muscles of the pelvic floor become weakened, impaired, or experience tension leading to a variety of complications. Due to the reactive nature and high demands of many sports, athletes are at increased susceptibility and of particular interest concerning PFD.

Hypothesis/purpose: The purpose of this study was to explore the prevalence of PFD among college-aged athletes, assess how PFD impacted athletic performance, and identify contributing factors for increased likelihood of PFD in athletes.

Study design: Cross-Sectional Study.

Methods: All fully active LVC NCAA Division 3 athletes were recruited for screening for PFD using the Cozean Pelvic Dysfunction Screening Protocol and were surveyed on their self-knowledge of PFD. Athletes who scored ≥ 3 on this tool completed an additional survey, created by the investigators, to identify the impact PFD had on their athletic performance and personal life and were then randomly assigned to one of three investigators to undergo a noninvasive coccygeal assessment to determine underactive, overactive, or normal pelvic floor muscle (PFM) activity.

Results: Fifty-three Division III male and female athletes between the ages of 18-25 years old participated in the study. Statistically significant differences were found between Cozean scores and demographic factors of age (p <0.001), gender (p <0.05), self-knowledge of PFD (p <0.001), and sport (p <0.001) among all participants that contributed to the increased likelihood of PFD. Thirteen athletes scored ≥ 3 on the Cozean with the 92.3% experiencing under/over active PFM activity and the majority indicating that PFD significantly impacted their athletic performance and quality of life.

Conclusion: The results indicate that older female NCAA Division III college athletes who participate in swimming and who possess self-knowledge of PFD are more likely to experience PFD. Additionally, these athletes are likely to encounter a significant impact on their athletic performance and quality of life. These results provide preliminary evidence on the need of PFD awareness and assessment among college athletes.

Background: Dynamic postural control (DPC) describes an individual's ability to maintain balance within their base of support in both anticipatory and reactive balance situations and has been measured using center of pressure (COP) velocity. Common standardized DPC assessments for active adults include the modified Star Excursion Balance Test (MSEBT) and the Y-Balance Test (YBT).

Hypothesis/purpose: The purpose of this study was to explore DPC during performance of the MSEBT, the YBT, and a modified version of the YBT, the MYBT. It was hypothesized that feedback from the YBT/MYBT reach indicator would enhance DPC.

Study design: Cross-sectional study.

Methods: Twenty-one participants (9 females, 12 males, mean age 24.5±1.2 years) performed three trials in each direction (anterior-AN, posteromedial-PM, and posterolateral-PL) on each balance test during one session. The YBT frame was placed atop a force plate for all testing. Frontal and sagittal plane COP velocities (COPx and COPy, respectively) were recorded throughout each trial and resultant COP (COPr) velocities were calculated.

Results: Significant main effects were present for test (F=4.485, p<0.001) and reach direction (F=61.594, p<0.001). Post hoc analyses for test indicated significant differences in COPy between YBT and MSEBT (p=0.034) and between MYBT and MSEBT (p<0.001), as well as significant differences in COPr between MYBT and MSEBT (p=0.002). Post hoc analyses for reach direction revealed significant differences in COPx between AN and both PM (p<0.001) and PL (p<0.001) directions, in COPy between AN and PM (p<0.001) and PL (p<0.001) directions, and COPr between AN and PL (p=0.043) directions only.

Conclusion: External proprioceptive feedback from the reach indicator improved DPC during the YBT and MYBT when compared to the MSEBT. Sagittal plane COP velocities were reduced when external proprioceptive feedback from the reach indicator was present, while frontal plane COP velocities were not affected in this group of participants.

Background: The Functional Movement Screen™ (FMS™) is widely used to assess functional movement patterns and illuminate movement dysfunctions that may have a role in injury risk. However, the association between FMS™ scores and LBP remains uncertain.

Objective: The purpose of this systematic review and meta-analysis was to examine functional movement scores among patients with low back pain (LBP) and healthy subjects with no LBP and review the validity of the FMS™ tool for screening functional movement among LBP patients.

Methods: The systematic review and meta-analysis included papers assessing functional movement among adult patients with LBP using the FMS™ through a literature review of five databases. The search strategy focused used relevant keywords: Functional movement screen AND low back pain. The review included all papers assessing functional movement among LBP adult patients (>18 years old) using the FMS™ published between 2003 to 2023. The risk of bias in the involved studies was evaluated using the updated Cochrane ROB 2 tool. Statistical analysis was conducted using Review Manager software, version 5.4. The meta-analysis included the total FMS™ score and the scores of the seven FMS™ movement patterns.

Results: Seven studies were included in this systematic review were considered to have low to unclear risk of bias. The meta-analysis revealed that the LBP group had a significantly lower total FMS™ score than the control group by 1.81 points (95% CI (-3.02, -0.59), p= 0.004). Patients with LBP had a significantly lower score than the control group regarding FMS™ movement patterns, the deep squat (p <0.01), the hurdle step (p <0.01), the inline lunge (P value <0.01), the active straight leg raise (p <0.01), the trunk stability push-up (p=0.02), and the rotational stability screens (p <0.01).

Conclusion: Lower scores on the FMS™ are associated with impaired functional movement. Identifying the specific functional movement impairments linked to LBP can assist in the creation of personalized treatment plans and interventions. Further research is needed to assess the association of cofounders, such as age, gender, and body mass index, with the FMS™ score among LBP patients and controls.

Background: Stretching programs are designed to improve hamstring flexibility by attempting to mechanically increase the length of the target tissue. However, other manual treatment approaches such as those utilized in Total Motion Release (TMR®), could be beneficial by identifying body asymmetries to assess and treat soft tissue impairments leading to diminished extensibility.

Purpose: The purpose of this study was to determine the effectiveness of the TMR® Fab 6 assessment and treatment to increase hamstring flexibility in healthy participants following one session of TMR®.

Study design: Observational Cohort study.

Methods: A convenience sample of 20 healthy participants (10 males, 10 females) were recruited from three institutions. Following collection of demographic information and a brief medical history, each participant performed a five minute warm-up on the stationary bike at a moderate intensity (80-90 RPMs) followed immediately by the bilateral performance of the Active Knee Extension Test (AKET) and Passive Straight Leg Raise (PSLR) to assess hamstring muscle length. Participants were randomly placed in the TMR® or control group. The TMR® group completed the "Fab 6" evaluation and treatment, while the control group performed one repetition of standing active hip flexion every 30-seconds for 15-minutes with both knees in full extension. Upon completion of treatment, control and TMR® groups were immediately re-evaluated on the AKET and the PSLR in the same order and fashion as baseline testing. Participants were asked to return in 24-hours for the same objective measurements as previously described.

Results: A significant time by group interaction was identified across all variables (p ≤ 0.001) for AKET and PSLR except the PSLR preferred leg from post-treatment to 24hr follow-up. The most significant increase in the AKET occurred in the TMR® group between baseline and post-treatment of the non-preferred leg (12.15°±2.94) when compared to the control group (7.15°±1.56).

Conclusion: The results of the study suggest that implementing a regionally interdependent treatment approach like TMR® results in significant improvements in hamstring extensibility and hip ROM compared to the control group.

Introduction: Adductor-related groin pain involves an injury to the common aponeurosis connecting the rectus abdominus and adductor longus to the pubis. It commonly occurs in sports that require cutting and pivoting and can result in significant loss of playing time. Platelet-Rich Plasma (PRP) is often indicated for treatment of musculoskeletal disorders and may represent an alternative treatment for patients with adductor-related groin pain. The purpose of this case report is to describe the non-surgical management of adductor-related groin pain in a competitive soccer player with a with an ultrasound (US)-guided PRP injection and physical therapy management.

Case description: A 17-year-old male competitive soccer player with right-sided adductor-related groin pain was treated with an US-guided PRP and a multi-phased physical therapy regimen based on tissue healing and individual patient/criteria progression. The patient completed 12 physical therapy sessions over six weeks post PRP injection.

Outcomes: At the end of treatment, clinically meaningful improvements were observed in pain intensity, passive range of motion, strength (handheld dynamometry, Biodex), functional tests, psychosocial (OSPRO-YF) and patient-reported outcomes (HAGOS, LEFS). The subject returned to sport at six weeks post injection without limitation and at three months follow up, the subject reported that he had returned to 95% of his previous level of play.

Discussion: This case report may offer support for PRP as an alternative treatment in the management of adductor-related groin pain. Incorporation of PRP as an adjunct to physical therapy led to improvements on all outcomes that surpassed the clinical significance change criteria.

The rotator cuff, comprising the subscapularis, supraspinatus, infraspinatus, and teres minor muscles, plays a crucial role in stabilizing the glenohumeral joint by securing the head of the humerus within the glenoid cavity of the scapula. The tendinous insertions of these muscles generate tension within the capsule, enhancing joint stability during muscular activity. The rotator cuff is susceptible to damage from disease, injury, or trauma, which can result in tears or ruptures of one or more tendons. The evaluation of the infraspinatus muscle and tendon is vital for diagnosing and managing various shoulder pathologies. Accurate imaging to determine the specific muscle involvement and injury severity significantly impacts treatment decisions. Diagnostic musculoskeletal ultrasound (MSK-US) has emerged as a valuable tool for assessing the infraspinatus muscle and tendon, offering real-time, dynamic assessment capabilities essential for precise diagnosis and effective rehabilitation planning. This article reviews the utility and advantages of MSK-US in evaluating the infraspinatus muscle and tendon, emphasizing technique specifics, diagnostic accuracy, and comparative efficacy against other imaging modalities. It details a systematic approach to the ultrasound examination technique for the infraspinatus, including patient positioning and identification of common pathologies such as tears, tendinopathy, and calcifications. With recent advancements in transducer strength, image resolution, and operator training, ultrasound serves as an excellent alternative imaging modality for diagnosing rotator cuff tears. This article aims to equip rehabilitation professionals with a comprehensive understanding of MSK-US as a diagnostic tool for the infraspinatus, promoting more precise diagnosis, treatment planning and improved patient outcomes.

Background: In 2020, the American Society of Shoulder and Elbow Therapists (ASSET) published an evidence-based consensus statement outlining postoperative rehabilitation guidelines following anatomic total shoulder arthroplasty (TSA).

Purpose: The purpose of this study was to (1) quantify the variability in online anatomic TSA rehabilitation protocols, and (2) assess their congruence with the ASSET consensus guidelines.

Methods: This study was a cross-sectional investigation of publicly available, online rehabilitation protocols for anatomic TSA. A web-based search was conducted in April 2022 of publicly available rehabilitation protocols for TSA. Each collected protocol was independently reviewed by two authors to identify recommendations regarding immobilization, initiation, and progression of passive (PROM) and active range of motion (AROM), as well as the initiation and progression of strengthening and post-operative exercises and activities. The time to initiation of various components of rehabilitation was recorded as the time at which the activity or motion threshold was permitted by the protocol. Comparisons between ASSET start dates and mean start dates from included protocols were performed.

Results: Of the 191 academic institutions included, 46 (24.08%) had publicly available protocols online, and a total of 91 unique protocols were included in the final analysis. There were large variations seen among included protocols for the duration and type of immobilization post-operatively, as well as for the initiation of early stretching, PROM, AROM, resistance exercises, and return to sport. Of the 37 recommendations reported by both the ASSET and included protocols, 31 (83.78%) were found to be significantly different between groups (p<0.05).

Conclusion: Considerable variability was found among online post-operative protocols for TSA with substantial deviation from the ASSET guidelines. These findings highlight the lack of standardization in rehabilitation protocols following anatomic TSA.

Background and purpose: Conservative management of anterior shoulder dislocation (ASD) is associated with greater recurrence compared with surgical management. Current rehabilitation protocols may not adequately challenge shoulder stability to encourage adaptive coping strategies. Apprehension-based training (ABT) is a new treatment concept derived from the supine moving apprehension test (SMAT), a previously validated performance measure among patients with ASD. The purpose of this case report is to describe the application of ABT in a patient with recurrent ASD.

Study design: Case report.

Case description: The subject was a 23-year-old male with bilateral recurrent ASD. The subject underwent a 17-week exercise program involving gradual exposure to increased anterior instability loads based on the SMAT movement pattern. The Western Ontario Shoulder Instability Index (WOSI), Patient-Specific Functional Scale (PFPS), Tampa Scale of Kinesiophobia, SMAT, shoulder internal and external rotation muscle strength were measured via hand-held dynomometry before and after training.

Outcomes: Following treatment, clinically meaningful gains in quality of life (WOSI) and shoulder function (PSFS) were noted. Kinesiophobia decreased, SMAT and shoulder internal rotator strength increased beyond their respective minimal detectable change. Four months after treatment, quality of life and shoulder function remained improved, and the subject reported a reduced rate of ASD.

Discussion: Apprehension-based training involving gradual exposure to shoulder instability loads may hold potential for improving the management of patients with ASD. Further testing of this concept is warranted.
