The influence of a hip extension strengthening programme on gait performance in individuals following stroke
… may be related to the commonly observed reduced hip extension in the stance phase of gait. The aim of this initial exploratory study was to evaluate the effects of a home-based strengthening programme on hip muscle strength and gait performance in individuals following stroke. Six chronic stroke …

Comparison in muscle activity between the back squat, Romanian deadlift and barbell hip thrust during hip extension
… such as back squat, Romanian deadlift (RDL), and hip thrust have been used by strength and conditioning specialists to target the musculature used during hip extension. Little is known about the differences in muscular activity of the hip extensors between these exercises, so it is not known which …

Biomechanical Sex Differences Between Freshman and Sophomore Athletes in a Single-Leg Squat and Single-Leg Land
… men and women with separating variables being hip extension, hip medial rotation and knee lateral rotation moments. All three variables were greater in men. Subgroups were separated by hip medial rotation, with freshmen men being greater than freshman and sophomore women. There were no sex …

The relationship of hamstring and hip flexor flexibility to injury rates in collegiate football players
… participate in the study to examine the relationship between flexibility and injury rate of muscle strain, specifically the Hamstring and Hip Flexor muscle groups. Participants were evaluated for range of motion and monitored for non-contact hamstring strains occurring throughout the competitive …

Does the use of upper leg compression garments aid performance and reduce post-race Delayed Onset Muscle Soreness (DOMS)?
… garment 2.50 vs control group 5.00) (p=0.02) and hip extension (compression garment 2.50 vs control group 4.00) (p=0.04) had a statistically significant difference between the compression garment and control group immediately post-race. VAS pain ratings for hamstring (compression garment 0.00 vs …

Assessing the Effects of Exoskeleton Use on Balance and Postural Stability
… extra weight, rigid structure, and external hip extension torque may increase demands on the postural control system. However, there is currently limited evidence on whether, and to what extent, BSE use alters postural stability and/or fall risk. The primary goal of this work was to …

The effects of a seven week slideboard training program
… test, strength and endurance tests of knee extension/flexion, hip extension/flexion, and hip adduction/abduction, and skinfold tests for body composition pre and post training. A one way repeated measures analysis of variance (ANOVA) showed significant increases in maximum heart rate (192.9 …

Biomechanics of cross-country skiing locomotion
… DST) has been described by authors as an extension of walking and running. Most biomechanical research studies have analysed the DST as a sporting activity leaving the locomotor strategies poorly described. This relationship to walking and running and the involvement of a gliding phase …

The Effects of Age on Gait and Functional Movement Characteristics in an Older Adult Population
… a joint kinetic strategy (including reduced hip extension moment) and altering gait (including a reduced walking speed). Increasing the task complexity was associated with altered gait patterns for this older adult group including a reduction in toe-clearance during manual dual task walking …

Do the gluteal muscles influence dynamic knee valgus when single-leg landing?
… are believed to have a role in controlling hip motion that is associated with dynamic knee valgus. Landing onto one leg is a common scenario of ACL injury mechanism and would appear to require considerable Gluteal muscle activity to control the forces if the relationship were true. Aim: the …

Evaluation of risk factors associated with patellofemoral pain syndrome
… Pain Syndrome (PFPS) and assess their relationship to PFPS. METHODS: The study was a retrospective study completed at Johns Hopkins Department of Orthopaedic Surgery. All patients, who were referred to physical therapy at Johns Hopkins Rehabilitation Therapy Services Clinic, were diagnosed with …

The Biomechanics of Sit-to-Stand and Physical Performance in Patellofemoral Osteoarthritis
… determine 1) the triplanar biomechanics of the hips and knees during sit-to-stand (STS) for persons with PFOA versus age- and gender-matched control subjects, 2) the impact of PFOA on physical performance, perceived functional status, and pain, and 3) the relationship between knee kinematics …

The Slippery Slope Between Falling And Recovering: An Examination Of Sensory And Somatic Factors Influencing Recovery After A Slip
… Slip Recovery Results: Increased time to peak hip extension (OR = 1.006, CI: 1.00-1.01) and ankle dorsiflexion (OR = 1.005, CI: 1.00-1.01) moments increased the odds of falling. While the average ankle moment was negatively associated with falling (OR = 0.001, CI: 0.001-0.005). Cortical …

The effect of unilateral cam femoroacetabular impingement on the three-dimensional kinematics of the pelvis and hip and the kinetics of the hip
… (ROM). This condition is known to decrease hip ROM, and has been reported to cause hip pain in a variety of daily activities including sitting and walking, and activities requiring large hip mobility. It is important to determine the effect of cam FAI on self-generated dynamic ROM and common …

THE VARIATION IN STRENGTH DECREMENT OF LOWER EXTREMITY MUSCLE GROUPS AND BIOMECHANICAL PLASTICITY IN OLDER ADULTS
… that one causal factor of BP with age is that hip extensor muscles are more similar in strength in young and old adults than are ankle plantarflexor muscles, thus enabling old adults to walk with larger mechanical contributions from hip muscles as compensation for reduced contributions from …

A Wearable Countermeasure for Musculoskeletal Deconditioning in Human Spaceflight
… in some muscles during upright standing, hip external rotation, hip extension, and knee flexion, with additional non-significant trends seen in other activities. These results aim to guide the development of exercise procedures for the GLCS countermeasure system and indicate that the GLCS …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
… Hamstring contraction creates knee flexion, hip extension and posterior pelvic tilt. Posterior pelvic tilt causes the lumbar spine to flatten (hypolordosis) which places pressure on the anterior structures of the spine, including the intervertebral disc. This increased pressure may predispose …

Role of Transverse Plane Hip Range of Motion and Strength on Pain and Function in Hip Osteoarthritis
Osteoarthritis (OA) of the hip is a chronic, progressive disease that decreases joint mobility and function and is associated with disability and musculoskeletal pain (Bieler et al., 2017; O’Neill et al., 2018; O’Neill & Felson, 2018; Rydevik et al., 2010). According to the Centers for Disease …
