Insertional Achilles tendinopathy (IAT) is a painful and debilitating condition that responds poorly to non-surgical interventions. It is thought that this disease may originate from compression of the Achilles tendon due to calcaneal impingement. Thus, compressive mechanical changes associated with IAT may elucidate its etiology and offer clues to guide(More)
UNLABELLED Orchestral musicians commonly have playing-related symptoms (PRS) but few use worker's compensation (WC) insurance for assessment and treatment. The purpose of this study was to examine the frequency of, and factors related to, filing a WC claim among musicians. METHODS An online questionnaire was completed by 261 members of the International(More)
Study Design Controlled laboratory study; cross-sectional. Background Little is known about ankle range of motion (ROM) and strength among patients with insertional Achilles tendinopathy (IAT) and whether limited ankle ROM and plantar flexor weakness impact IAT symptom severity. Objectives The purposes of the study were (1) to examine whether participants(More)
STUDY DESIGN Cross-sectional laboratory study. OBJECTIVE To compare single-limb heel-rise performance and foot-ankle kinematics between persons with stage 2 adult-acquired flat foot deformity (AAFD) and healthy controls. BACKGROUND The inability to perform a single-limb heel rise is considered a positive functional diagnostic test for AAFD. However,(More)
Heel lifts are commonly prescribed to patients with Achilles tendinopathy, yet little is known about the effect on tendon compressive strain. The purposes of the current study were to (1) develop a valid and reliable ultrasound elastography technique and algorithm to measure compressive strain of human Achilles tendon in vivo, (2) examine the effects of(More)
STUDY DESIGN Case-control laboratory study. OBJECTIVES To compare tendon characteristics (shape, composition) and mechanical properties (strain, stiffness) on the involved side of participants with insertional Achilles tendinopathy (IAT) to the uninvolved side and to controls, and to examine if severity of tendon pathology is associated with severity of(More)
Heterosexual transmission of HIV often occurs in the context of intimate sexual partnerships. There is mounting evidence that couple-based HIV prevention interventions may be more effective than individual-based interventions for promoting risk reduction within such relationships. Yet, concerns have been raised about the safety of couple-based prevention(More)
UNLABELLED Many risk factors have been identified as contributing to the development or persistence of low back pain (LBP). However, the juxtaposition of both high and low levels of physical activity being associated with LBP reflects the complexity of the relationship between a risk factor and LBP. Moreover, not everyone with an identified risk factor,(More)
OBJECTIVES To examine (1) the validity of ultrasound imaging to measure osteophytes and (2) the association between osteophytes and insertional Achilles tendinopathy (IAT). DESIGN Case-control study. SETTING Academic medical center. PARTICIPANTS Persons with chronic unilateral IAT (n=20; mean age, 58.7±8.3y; 10 [50%] women) and age- and sex-matched(More)
BACKGROUND Clinicians use the lunge position to assess and treat restricted ankle dorsiflexion. However, the individual forefoot and rearfoot contributions to dorsiflexion and the potential for abnormal compensations are unclear. The purposes of this case-control study were to 1) compare single- (representing a clinical lunge position measure) versus(More)
