Prevalence of Pain With Movement in Active Duty US Army Soldiers.

INTRODUCTION: Soldiers must be able to perform a multitude of physically demanding tasks as part of their regular duty, but their physical readiness is often degraded due to pain and musculoskeletal injury (MSKI). The presence of pain with movement has been associated with increased MSKI risk in Soldiers. Improved awareness of the prevalence of painful movements in uninjured Soldiers could help inform Army injury mitigation efforts. The purpose of this study was to identify the prevalence of pain with movement in a population of healthy active duty Soldiers. MATERIALS AND METHODS: The Selective Functional Movement Assessment-Top Tier Movements (SFMA-TTM), active range of motion (AROM) of the hips and shoulders, and the elicitation of pain with movement were measured in 268 healthy US Army Soldiers. Descriptive statistics were generated for the number of painful movements for each measure and inferential statistics; independent t-test and one-way independent analysis of variance (ANOVA) were used for analysis of the other measures. RESULTS: Greater than half (59%) of the participants reported pain with at least 1 movement and more than 41% reported pain with 2 or more movements. Soldiers reported a mean of 1.35 painful movements on the SFMA-TTM assessment and a mean of 1.54 painful AROM movements. CONCLUSIONS: Pain with functional movement patterns was common across a sample of uninjured Soldiers. The presence of pain with movement warrants further evaluation as it may impact a Soldier's physical performance, risk for future injury, and overall quality of life.

Timing of Outcomes and Expectations After Knee Surgery in the US Military: A Systematic Review.

CONTEXT: Knee injury and subsequent surgery are widespread in the military setting. Associations between knee surgery and expected outcomes over time have not been consolidated and characterized systematically by procedure type across the body of literature, and the temporal expectations of these outcomes remain unclear. OBJECTIVE: To summarize common postoperative follow-up times and associated outcomes that determine clinical or surgical failure in US service members after elective knee surgery. DATA SOURCES: A systematic search was conducted with 3 bibliographic databases of published research reports from 2010 through 2021. STUDY SELECTION: Studies in US military service members undergoing elective knee surgery, with a minimum of 1-year follow-up, and reporting on a functional/occupational outcome were included. Three reviewers screened all abstracts and full-text articles to determine eligibility. STUDY DESIGN: Systematic review of longitudinal cohort studies. LEVEL OF EVIDENCE: Level 2a. DATA EXTRACTION: Extracted data included military demographics, surgical procedure variables, surveillance period, and outcome measures. The Newcastle-Ottawa Scale and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to determine study quality and risk of bias. RESULTS: A total of 22 studies (mean follow-up time of 40.7 months) met the inclusion criteria. For cruciate ligament repair, approximately one-third of patients required a second surgery or were medically separated from military service by 2 years from surgery; 100% were reinjured by 4 years, and 85% sustained a new injury within 5 years of surgery. For meniscal repair, nearly one-third of patients were medically separated, and half were placed on activity restrictions within 3 years of surgery. For articular cartilage repair, within 5 years, 39% of patients required a second surgery, 30% were placed on activity restrictions, and 36% were medically separated. For patellar repair, 37% of patients were medically separated and over half were placed on activity restrictions within 5 years. CONCLUSION: Common knee surgeries can have long-term implications for military careers that may not become apparent with shorter follow-up periods (<2 years). When longer surveillance periods are used (eg, up to 5 years), additional surgical procedures are more common and the likelihood of being injured or medically separated from military service is higher.

Upper Extremity Superficial Vein Thromboses Presenting as Acute Neck Pain in a Young and Healthy Male: A Case Report.

BACKGROUND AND PURPOSE: Neck pain in the United States is pervasive and contributes to disability. While the majority of neck pain in young and healthy individuals is neuromusculoskeletal in nature, screening for red flags is necessary for ruling-out serious medical pathologies. The purpose of this case report is to describe a young and healthy male subject with a primary complaint of acute neck pain with multiple underlying upper extremity superficial vein thromboses (UESVTs). CASE DESCRIPTION: The subject was a 27-year-old male active-duty Soldier referred to physical therapy by his primary care provider (PCP) for acute left-sided neck pain. Prior to physical therapy, the subject had been treated with cyclobenzaprine, oxycodone-acetaminophen, trigger point injection and had undergone a D-dimer to rule out a potential thrombus due to air travel and lower extremity immobilization. OUTCOMES: The subject underwent a D-dimer, Doppler ultrasound, pharmacological treatment of Rivaroxaban, and was referred to hematology/oncology to rule out systemic causes of SVTs. Evidence of subtle increases in blood pressure over the course of three months, a positive D-dimer, and symptoms incongruent with clinical presentation contributed to referral to a hematology/oncology specialist and a diagnosis of multiple UESVTs. The subject was able to return to his previous level of activity by six months and remained free of SVTs at two-year follow-up. DISCUSSION: UESVT events are rare and can be challenging to identify. This case report describes a unique presentation of acute neck pain caused by underlying UESVTs in an otherwise healthy and active young male. LEVEL OF EVIDENCE: Level 4.

Clinical measures associated with dynamic balance and functional movement.

Decreased balance and impaired functional movement have been linked with increased injury risk. The purpose of our study was to determine the association between specific measures of power, strength, flexibility, balance, and endurance compared with more global measures of dynamic balance, using the Y-Balance Test (YBT), and functional movement, using the functional movement screen (FMS), in healthy soldiers. Our participants (n = 64; 53 men, 11 women) were healthy active duty service members (25.2 ± 3.8 years, 25.1 ± 3.1 kg·m(-2)). Seventeen tests with 38 associated measures of strength, power, flexibility, endurance, balance, and functional measures were assessed. A significant Pearson product moment correlation (r > 0.2 and p < 0.01) was used to narrow the number of variables of interest. Two hierarchical stepwise regression analyses were performed to determine the most parsimonious set of variables associated with the YBT and FMS performance scores. Our results included a 4 variable model (F = 13.4, p < 0.001) that was associated with YBT scores (R = 0.72, R2 = 0.51). Superior performance on the YBT was associated with better performance on the FMS lunge and upper trunk mobility tests, decreased number of hops during a 6-m hop test, and greater gastrocnemius flexibility. A second 4 variable model (F = 11.813, p < 0.001) was associated with FMS scores (R = 0.70, R2 = 0.50). Superior performance on the FMS was associated with greater anterior reach on the YBT, greater distance on the crossover hop test, increased hamstring flexibility, and higher levels of self-reported function through the lower-extremity functional scale. Physical fitness leaders and clinicians could use these models to inform decision making when developing and assessing the outcomes of a personalized intervention program for those with low FMS and YBT scores.
