Military training is associated with a high incidence of knee pain. Conversion from rearfoot to non-rearfoot strike during running effective at reducing pain in research environments. The purpose this report was demonstrate run retraining as clinical intervention for service members pain.Sixteen running-related chronic underwent that converted foot using real-time visual feedback. Lower Extremity Functional Scale (LEFS) and Numerical Pain Rating (NPRS) were assessed pretraining, the final...
Passive dynamic ankle-foot orthoses have potential to facilitate return running after a lower limb trauma. However, transitioning patients new movement patterns that enhance passive benefits can pose challenge. The purpose of this case study was report biomechanical and functional outcomes for patient utilizing following completion session-based, midfoot strike run training program.A using due surgically reconstructed tibia\fibula fracture underwent eight treadmill sessions over 2 weeks...
Abstract Controlled trunk motion is crucial for balance and stability during walking. Persons with lower extremity amputation often exhibit abnormal motion, yet underlying mechanisms are not well understood nor have optimal clinical interventions been established. The aim of this work was to characterize associations between altered joint moments dynamics in persons unilateral, transtibial (TTA). Full-body gait data were collected from 10 TTA uninjured walking overground (~1.4 m/s)....
Weight gain can contribute to osteoarthritis, cardiovascular disease, low back pain, and poor health-related quality of life. trajectory patterns have been described in older veterans with limb loss; however, there is limited evidence changes weight younger loss.Service members unilateral or bilateral lower amputations (LLAs) (and without an upper amputation) were included this retrospective cohort analysis (n = 931). The mean postamputation baseline was 78.0 ± 14.1 kg. Bodyweight...
ABSTRACT Introduction Wounded service members with amputations undergo a complex rehabilitation regimen that can often become complicated by skin breakdown, heterotopic ossification (HO), and pain of the residual limb, contralateral or low back. These complications impact prosthetic socket fit, decreasing one's functional independence, potentially negatively quality life. The purpose this report is to present case involving treatment HO along modifications, intention address back (LBP), in...
Surgical attempts at lower limb preservation after trauma may be complicated by pain and gait disturbances, which can impact the activity level of a military service member. It is unclear how later transtibial amputation (TTA) might affect patients who elect this option preservation.The purposes study were to compare preamputation postamputation (1) numeric rating scale for medication use; (2) self-reported level, Four Square Step Test (FSST) results, assistive device (3) spatiotemporal...
ABSTRACT Symptomatic cervical spondylosis is a progressive degenerative condition of the spine commonly resulting in functionally-limiting pain, weakness, and/or limited dexterity. believed to occur at higher rates military aviators than civilian counterparts and disqualifying for all Navy Marine Corps aircrew. This non-waiverable tactical jet (ejection-seat-based) aviators. Medical attrition experienced aircrew from aviation community results substantial cost U.S. Government, reduces fleet...
Ankle sprains are the most common musculoskeletal injury in sport and military activity, despite existing prophylactic strategies. The purpose of this report was to develop a probabilistic simulation lateral ankle during single-limb drop landing, towards accelerating innovation sprain prevention. A deterministic, subject-specific model extended with automation distributions on sprain-related biomechanical factors. Probabilistic simulations were generated using traditional Monte Carlo...
ABSTRACT Introduction Running-related injuries are prevalent in the military and often related to physical fitness test training. Non-rearfoot striking while running is known increase risk of Achilles tendon because high eccentric energy absorption by elastic components planarflexor muscle-tendon complex. However, there limited evidence suggest benefits converting runners with pain use a rearfoot strike. Methods This case series two active-duty Service members chronic, running-related that...
