limited ankle dorsiflexion increases the risk for mid portion achilles tendinopathy in infantry recruits a prospective cohort study
Journal of Foot and Ankle Research, 2014Co-Authors: Alon Rabin, Zvi Kozol, Aharon S FinestoneAbstract:Achilles tendinopathy (AT) is a prevalent condition among runners and military personnel. Although ankle dorsiflexion (DF) range of motion (ROM) as measured with the knee bent has not been previously associated with AT, the literature concerning its role is limited. In addition, the role of lower extremity Movement Pattern in the pathogenesis of AT has not been studied prospectively. The purpose of this study was to further explore the role of ankle DF ROM as measured with the knee bent and that of lower extremity Movement Pattern as risk factors for mid-portion AT. Seventy healthy male military recruits (mean ± SD age, height and body mass of 19.6 ± 1.0 years, 176.0 ± 10.0 cm, and 71.5 ± 7.4 kg) participated in this study. Ankle DF ROM as measured with the knee bent in weight-bearing (WB) and non-weight-bearing (NWB), as well as lower extremity quality of Movement during a lateral step down (LSD) test were measured at baseline. Participants were then followed for a 6-month period of army basic training with recording of the development of AT. Five participants developed AT during training. Participants that developed AT had a more limited NWB ankle DF ROM (27.40 versus 21.10, p = 0.025). The quality of lower extremity Movement did not differ between injured and uninjured participants (p = 0.361). A more limited ankle DF ROM as measured in NWB with the knee bent increases the risk of developing AT among military recruits taking part in intensive physical training.

factors associated with visually assessed quality of Movement during a lateral step down test among individuals with patellofemoral pain
Journal of Orthopaedic & Sports Physical Therapy, 2014Co-Authors: Alon Rabin, Zvi Kozol, Uria Moran, Arye Efergan, Yehuda Geffen, Aharon S FinestoneAbstract:Study Design Cross-sectional. Objective To determine what physical measures are associated with visually assessed quality of Movement among patients with patellofemoral pain (PFP). Background An altered Movement Pattern has been implicated as a risk factor for PFP. An understanding of physical measures associated with an altered Movement Pattern could potentially help guide prevention and management efforts in patients with PFP. Methods Seventy-nine (40 women) Israel Defense Forces soldiers referred to physical therapy with a diagnosis of PFP were included. Movement Pattern was assessed visually during a lateral step-down test and rated as “good” or “moderate,” based on previously established criteria. Weight-bearing and non-weight-bearing ankle dorsiflexion (DF) range of motion (ROM); hip internal and external rotation ROM; and hip abduction, hip external rotation, and knee extension strength were also assessed. Differences in physical measures between those with good versus moderate quality of Movement ...

measures of range of motion and strength among healthy women with differing quality of lower extremity Movement during the lateral step down test
Journal of Orthopaedic & Sports Physical Therapy, 2010Co-Authors: Alon Rabin, Zvi KozolAbstract:Study Design Cross-sectional. Objective To determine the association between hip and ankle range-of-motion measures, as well as measures of hip muscle strength, with measures of quality of lower extremity Movement, as assessed visually during the lateral step-down test in healthy women. Background Altered lower extremity Movement Pattern consisting of excessive femoral adduction and internal rotation, leading to excessive knee valgus alignment, is associated with increased risk of knee ligament injury, as well as patellofemoral pain syndrome. Previous investigations of lower extremity kinematics, using 3-dimensional motion analysis systems, document an inconsistent association between hip muscle strength and lower extremity Movement Pattern. Currently, it is unknown whether differences in hip muscle strength or other physical measures exist among women with differing quality of lower extremity Movement as assessed by visual observation. Methods Two physical therapists assessed the quality of Movement duri...

immediate effects of a single session of motor skill training on the lumbar Movement Pattern during a functional activity in people with low back pain a repeated measures study
Physical Therapy, 2018Co-Authors: Andrej V Marich, Gretche Salsich, Vanessa M Lanie, Catherine E Lang, Linda R Van DilleAbstract:Background People with low back pain (LBP) may display an altered lumbar Movement Pattern of early lumbar motion compared to people with healthy backs. Modifying this Movement Pattern during a clinical test decreases pain. It is unknown whether similar effects would be seen during a functional activity. Objective The objective of this study was to examine the lumbar Movement Patterns before and after motor skill training, effects on pain, and characteristics that influenced the ability to modify Movement Patterns. Design The design consisted of a repeated-measures study examining early-phase lumbar excursion in people with LBP during a functional activity test. Methods Twenty-six people with chronic LBP received motor skill training, and 16 people with healthy backs were recruited as a reference standard. Twenty minutes of motor skill training to decrease early-phase lumbar excursion during the performance of a functional activity were used as a treatment intervention. Early-phase lumbar excursion was measured before and after training. Participants verbally reported increased pain, decreased pain, or no change in pain during performance of the functional activity test Movement in relation to their baseline pain. The characteristics of people with LBP that influenced the ability to decrease early-phase lumbar excursion were examined. Results People with LBP displayed greater early-phase lumbar excursion before training than people with healthy backs (LBP: mean = 11.2°, 95% CI = 9.3°-13.1°; healthy backs: mean = 7.1°, 95% CI = 5.8°-8.4°). Following training, the LBP group showed a decrease in the amount of early-phase lumbar excursion (mean change = 4.1°, 95% CI = 2.4°-5.8°); 91% of people with LBP reported that their pain decreased from baseline following training. The longer the duration of LBP (β = - 0.22) and the more early-phase lumbar excursion before training (β = - 0.82), the greater the change in early-phase lumbar excursion following training. Limitations The long-term implications of modifying the Movement Pattern and whether the decrease in pain attained was clinically significant are unknown. Conclusions People with LBP were able to modify their lumbar Movement Pattern and decrease their pain with the Movement Pattern within a single session of motor skill training.

reduced hip adduction is associated with improved function after Movement Pattern training in young people with chronic hip joint pain
Journal of Orthopaedic & Sports Physical Therapy, 2018Co-Authors: Marcie Harrishayes, Linda R Van Dille, Kare Stegermay, Mario Schootma, Gretche Salsich, Sylvia Czuppo, Joh C Clohisy, Paul K Commea, Travis J Hille, Shirley A SahrmaAbstract:Study Design Ancillary analysis, time-controlled randomized clinical trial. Background Movement-Pattern training (MPT) has been shown to improve function among patients with chronic hip joint pain (CHJP). Objective To determine the association among treatment outcomes and mechanical factors associated with CHJP. Methods Twenty-eight patients with CHJP, 18 to 40 years of age, participated in MPT, either immediately after assessment or after a wait-list period. Movement-Pattern training included task-specific training to reduce hip adduction motion during functional tasks and hip muscle strengthening. Hip-specific function was assessed using the Modified Harris Hip Score (MHHS) and Hip disability and Osteoarthritis Outcome Score (HOOS). Three-dimensional kinematic data were used to quantify hip adduction motion, dynamometry to quantify abductor strength, and magnetic resonance imaging to measure femoral head sphericity using the alpha angle. Paired t tests assessed change from pretreatment to posttreatment....

consistency of a lumbar Movement Pattern across functional activities in people with low back pain
Clinical Biomechanics, 2017Co-Authors: Andrej V Marich, Chingting Hwang, Gretche Salsich, Catherine E Lang, Linda R Van DilleAbstract:Background Limitation in function is a primary reason people with low back pain seek medical treatment. Specific lumbar Movement Patterns, repeated throughout the day, have been proposed to contribute to the development and course of low back pain. Varying the demands of a functional activity test may provide some insight into whether people display consistent lumbar Movement Patterns during functional activities. Our purpose was to examine the consistency of the lumbar Movement Pattern during variations of a functional activity test in people with low back pain and back-healthy people. Methods 16 back-healthy adults and 32 people with low back pain participated. Low back pain participants were classified based on the level of self-reported functional limitations. Participants performed 5 different conditions of a functional activity test. Lumbar excursion in the early phase of Movement was examined. The association between functional limitations and early phase lumbar excursion for each test condition was examined. Findings People with low back pain and high levels of functional limitation demonstrated a consistent Pattern of greater early phase lumbar excursion across test conditions (p < 0.05). For each test condition, the amount of early phase lumbar excursion was associated with functional limitation (r = 0.28–0.62). Interpretation Our research provides preliminary evidence that people with low back pain adopt consistent Movement Patterns during the performance of functional activities. Our findings indicate that the lumbar spine consistently moves more readily into its available range in people with low back pain and high levels of functional limitation. How the lumbar spine moves during a functional activity may contribute to functional limitations.

the effects of Movement Pattern modification on lower extremity kinematics and pain in women with patellofemoral pain
Journal of Orthopaedic & Sports Physical Therapy, 2012Co-Authors: Gretche Salsich, Valentina Graci, Dwayne E MaxamAbstract:Study Design Controlled laboratory study. Objectives To compare hip and knee kinematics and pain during a single-limb squat between 3 Movement conditions (usual, exaggerated dynamic knee valgus, corrected dynamic knee valgus) in women with patellofemoral pain. Background Altered kinematics (increased hip adduction, hip medial rotation, knee abduction, and knee lateral rotation, collectively termed dynamic knee valgus) have been proposed to contribute to patellofemoral pain; however, cross-sectional study designs prevent interpreting a causal link between kinematics and pain. Methods The study sample included 20 women with patellofemoral pain, who demonstrated observable dynamic knee valgus. Participants performed single-limb squats under usual, exaggerated, and corrected Movement conditions. Pain during each condition was assessed using a 0-to-100-mm visual analog scale. Hip and knee frontal and transverse plane angles at peak knee flexion and pain levels were compared using repeated-measures 1-way analys...
