E-mail address: [email protected] (Y. Palad) Introduction/Background Varus thrust is a gait deviation and a known risk factor for knee osteoarthritis. Prevalence of varus thrust and normative values of stance-phase knee deviation across the lifespan are unknown. The aim of the study was to report prevalence of varus thrust and normative values for hip-knee-ankle (HKA) angle deviation across the lifespan, and to explore associations between HKA angle deviation and selected clinical factors. Material and method This is a cross-sectional study of 572 participants from the 1000 Norms Project. People aged 3–101 years who self-reported as being healthy were eligible to participate. Video recordings (2D) of frontal plane gait were analysed for presence of varus or valgus thrust and quantification of HKA angle deviation (difference between HKA angles at initial contact and mid-stance). Correlation and multiple regression analyses explored the relationship between HKA angle and age, sex, body mass index (BMI), alignment, knee and hip strength, Knee Injury and Osteoarthritis Outcomes Scores (KOOS), foot posture index, gait parameters, and hypermobility.

Results Thirty-one percent (31%) of the cohort had varus thrust. This was most prevalent among adults > 60 years (42%) and children < 10 years (41%), and was also common in adolescents (25%) and adults aged 20–59 (23%). Mean HKA angle deviation for the entire cohort was 1.2◦ (95% CI: 1.07–1.36), and 2.1◦ (95% CI: 1.84–2.36) among people with clinical varus thrust. BMI, stride width, KOOS-Sports for adolescents, and height for adults were independently associated with HKA angle deviation. Conclusion Varus thrust is prevalent across the lifespan. Normative values established here can be readily used by clinicians and researchers in monitoring this deviation.

Gender and laterality differences on measurements of acromiohumeral distance (AHD) at rest and at shoulder abduction using musculoskeletal ultrasound in asymptomatic Filipino adults
M.N. Gelvosa ∗ , A. Azarcon Veterans Memorial Medical Center, Department of Rehabilitation Medicine, Quezon City, Philippines ∗ Corresponding author. E-mail address: [email protected] (M.N. Gelvosa) Introduction/Background Musculoskeletal ultrasound is increasingly becoming a popular tool in the diagnosis of musculoskeletal disorders with the shoulder as one of the most routinely scanned joints. Common causes of shoulder pain, such as subacromial impingement syndrome and rotator cuff tendinopathy, have been shown to be associated with reduced acromiohumeral distance. This study aimed to determine mean ultrasonographic acromiohumeral distance and compare measurements between male and female Filipino adults, dominant and non-dominant side, at neutral shoulder position and at 60◦ abduction. Secondarily, it aimed to determine interrater reliabiliy of ultrasonographic measurements. Material and method This study employed a cross-sectional observational study design. AHD was measured on both shoulders of forty-one volunteers, 15 males and 26 females with mean age 22.1 and 22.3 respectively, at neutral shoulder position and at 60◦ of passive abduction by two different raters.
