Valve characterization to implement feed-forward control of hydraulically actuated joints
… hydraulic cylinders was constructed to decouple joint movement, and multiple tests were conducted, recording cylinder velocities given a constant pwm signal at a system pressure of 3.45MPa. After theoretically justifying the empirical results, a quadratic and bi-linear curve fit to the data …

INCREASE IN 1RM BACK SQUAT AFTER ABDOMINAL STABILIZING MANEUVERS
… can protect the lumbar spine from excess movement; a cause of lower back pain. Abdominal bracing (AB) and abdominal hollowing (AH) are two stabilizing maneuvers that increase IAP. Previous literature primarily compared AH and AB in therapy settings on bodyweight single joint movements. The …

Improvement of hand and finger function in systemic sclerosis: game-based intervention informed by a 3D assessment of hand mobility
… throughout functional tasks, as well as joint specific contributions to overall impairment. Study one showed that patients have significant movement impairment throughout the entire movement phase of functional tasks. Further impairments were found in all joints and movement directions, …

A model for the time dependent behaviour of rock joints
… into the time-dependent behaviour of rock joints. Much of the research work that has been conducted to date in the area of finite element analysis has been involved with the development of special elements to deal with these discontinuities. A comprehensive literature survey is undertaken …

Development of user-friendly system of flexible electrogoniometers for use in total knee arthroplasty
… sufficient information regarding their knee joint movement during various activities of daily living (ADL) was developed.The project aimed to produce ‘A user friendly version of flexible electrogoniometers’; namely, Strathclyde University Data Logging System (SUDALS). The newly developed …

An intelligent prosthetic hand using hybrid actuation and myoelectric control
… as active bending is limited to two or three joints and user-unfriendliness. These limitations are present in commercial prosthetic hands, together with others always complained about by patients and amputees, such as inability to provide enough grasping functionality and heavy weight. Several …

Quantification of Cumulative Load on the Knee using a Vibration Emission Method
… can induce heavy mechanical loads on the joint, causing the articulating surfaces to deform. This can result in changes of vibration characteristics of the joint surfaces. Differences in the vibration characteristics of normal and pathological joints have been established and used in the …

Chondrocyte Regulation by IL-I and IGF-I: Interconnection Between Anabolic and Catabolic Factors
… mechanical stresses associated with diarthrodial joint movement, protecting these joints over a lifetime of use. Tissue function is maintained through the balance between synthesis and resorption (i.e., metabolism) of extracellular matrix (ECM) by articular chondrocytes (ACs). Two important …

Characterizing the Effects of Histotripsy for Osteosarcoma Treatment on Tendon Structure and Function
… musculoskeletal structures that facilitate joint movement. The objective of this study is to evaluate the effects of histotripsy on tendon structure and function via biomechanical testing, ultrasound (US) image texture analysis, and histologic analysis. In this ex vivo model, canine extensor …

Beyond jump height: Understanding the kinematics and kinetics of the countermovement jump from vertical ground reaction force data through the use of higher-order time derivatives
The countermovement jump (CMJ) is a complex, multi-joint movement that has been well studied in human research, largely through analysis of the ground reaction force-time signal obtained during jumping. Such analysis has required the definition and then the calculation of several critical kinematic …

Development of a novel test rig for the evaluation of aircraft fuel tank sealants
… upon sealant materials to prevent leakage past joints and fasteners. However, the wing is designed as a structural member first and as a fuel tank second and there exist many potential leak paths for the fuel from these complex, highly loaded structures. Fuel leaks result in direct loss of fuel …

Elbow exoskeleton mechanism for multistage poststroke rehabilitation.
… a series of biomechanical exercises- controlled joint movement in acute phase; external assistance in the mid phase; and variable levels of resistance in the last phase. Post-stroke rehabilitation performed by physiotherapist has many limitations including cost, time, repeatability and intensity …

Trail runners: Neuromuscular and biomechanical insights
… to habitual terrain targeted at minimising ankle joint movement during weight-bearing. Subsequently, we aimed to determine whether running biomechanics would differ between 20 habitually shod trail runners and 20 road running counterparts due to their preferred training terrain. A special focus of …
