Neural and Collagen Tissue Properties As They Relate to Glenohumeral Joint Laxity and Stiffness
… or a traumatic event that leads to excessive joint laxity. A major concern with instability is the high recurrence rate post treatment. Although the occurrence and recurrence of instability are primarily associated with capsule and labrum injury, the tissue characteristics of the capsule and …

Changes in joint laxity associated with the menstrual cycle, with pregnancy, with the post-partum period, and with the menopause
This thesis looks at changes in joint laxity associated with the menstrual cycle, pregnancy, and the menopause and the potential contribution of female hormones to that laxity. A pilot study revealed that there was a potential link between the phases of the menstrual cycle and the onset of …

Changes in Neuromuscular Performance Throughout the Menstrual Cycle in Physically Active Females
… at 60°/sec, 180°/sec, and 300°/sec, and knee joint laxity were measured at each visit. Main Outcome Measures: Isokinetic quadriceps strength, KT- 1000 measurements, blood assays. Results: Isokinetic peak torque at 60°/sec was significantly lower during the follicular (151.6 ± 26.8 NM) than …

Proprioception, balance and lower limb strength in Nigerian children (7-10 years) with Generalized Joint Hypermobility and Developmental Coordination Disorder
… as having a higher prevalence of generalised joint hypermobility (GJH) than their Caucasian counterparts. It is believed that abnormal joint biomechanics as a result of the joint laxity contribute to the damage of joints. The ability to perceive movement or position sense at joints …

Failure of Primary Total Knee Arthroplasty: Establishing a Baseline for Retrieval Analysis Using Well-Functioning Necropsy Specimens
… investigate the relationship between soft tissue laxity, inflammatory cytokine concentrations, tissue metal concentrations, and wear scores of well-functioning implants retrieved from cadaveric specimens to determine the role of each of these factors in implant survivorship. It was hypothesized …

Explicit Finite Element Modeling of Knee Mechanics During Simulated Dynamic Activities
… natural knee is one of the most commonly injured joints in the body due to relatively high loads and motions that can lead to debilitating degenerative diseases such as osteoarthritis. Total knee arthroplasty is a clinically successful method for eliminating pain in the osteoarthritic knee, but is …

The Effects of Oral Contraceptive Use on Ligamentous Injury Incidence in Females: A Potential for Prevention
… Increased serum estrogen levels increase ACL laxity and potentially are to blame for an increased injury risk. Estrogen receptors located within human ACL fibroblasts, when activated, decrease collagen production, which leads to decreased ligament strength and increased laxity. Estrogen levels …

Sex differences in the neural control of muscle
… pennation angle or a tendency towards greater joint laxity. Higher motor unit discharge rates and incidence of doublets may increase twitch force summation leading to a reduction in FS. Thus, biomechanical, not inherent sex-differences in neural drive led to neural compensation strategies …

The Reliability of Instrumented Knee and Ankle Orthopedic Special Tests Performed with A LigMaster™ Multijoint Arthrometer
Context: Knee and ankle joint arthrometers are designed to increase the precision and objectivity of clinical measures of joint laxity and mechanical stiffness. The LigMaster™ is a relatively new multijoint arthrometer that can be used to perform instrumented orthopedic special tests at the knee, …

A Comparison of Strength, ROM, Laxity, and Dynamic and Static Postural Control Between Those At-Risk and Healthy
… of this study were to compare strength, ankle joint laxity, ankle dorsiflexion range of motion (DF-ROM), and static balance between individuals with poor and good performance on the Star Excursion Balance Test in the anterior reach direction (SEBT-A), as well as to identify what combination of …

An Examination of Contributing Factors to Star Excursion Balance Test in Individuals with and without Chronic Ankle Instability
… dorsiflexion range of motion (DFROM), and ankle laxity between individuals with and without chronic ankle instability (CAI) as well as to determine which factors contribute the most to Star Excursion Balance Test (SEBT) performance in the CAI and healthy control groups. Design: A case-control …

The Effect of a Specialized Yoga Intervention on Characteristics of Functional Ankle Instability
… to musculoskeletal structures in the ankle joint complex causing pathological joint laxity or arthrokinematics restrictions. Functional ankle instability (FAI) is defined by the ankle giving way, in which a person experiences instability due to a near-sprain as a result of a benign or even …

A longitudinal study on possible correlates that might explain the onset and progression of musculoskeletal symptoms in school-aged children with Generalized Joint Hypermobility
Background: Generalized Joint Hypermobility (GJH) is an increased joint range of motion in multiple joints. Its prevalence in the general population is usually a function of age, gender, ethnicity and Beighton score cut-off score. GJH has been documented to be beneficial to sports and activities …

Lower leg and foot contributions to turnout in pre-professional female dancers: A clinical and kinematic analysis
… the legs, is produced through the summation of joint structure characteristics and ranges of motion at the hip, knee, ankle and foot. The hip joint’s contribution to functional turnout, a dancer’s preferred turnout stance, has received extensive examination, whereas little is known about …

Screening for risk factors associated with non-specific shoulder pain in mail adolescent water polo players
… muscles, altered GH range of motion (ROM), GH joint laxity, high training loads, pectoralis minor tightness and altered scapular control. In other overhead throwing sports the risk factors include altered GH ROM and glenohumeral internal rotation deficit (GIRD), shoulder muscles weakness, …

Movement patterns in the unstable total knee replacement
… TKA patients with varying degrees of knee joint laxity suggested that some patients are able to develop coping mechanisms to stabilise the knee, whereas others do not (Hamilton et al., 2020). Thus, the concept of “secondary (muscular) stabilisers” was proposed for controlling movement about …

Genetic risk factors for overuse and acute musculoskeletal injuries
… rotation range of motion, (iii) clinical joint laxity and instability and (iv) internal/external rotation strength. Although previously associated in some studies investigating other overuse musculoskeletal soft tissue injuries, none of the investigated collagen variants were independently …
