Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

Effect of Arm Pivot Joints on Stiffness Discrimination in Haptic Environments

Multimodal Technologies and Interaction, 2022
We investigated the effect of arm pivot joints that are typically used during haptic exploration by evaluating four joints of the human arm (metacarpophalangeal joint of the index finger, wrist, elbow, and shoulder joints).

Sensitivity of Lower-Limb Joint Mechanics to Prosthetic Forefoot Stiffness with a Variable Stiffness Foot in Level-Ground Walking

Journal of Biomechanics, 2023
This paper presents the effects of the Variable Stiffness Foot (VSF) on lower-limb joint mechanics in level-ground walking. Persons with transtibial amputations use lower-limb prostheses to restore level-ground walking, and foot stiffness and geometry ...

Torque and workspace analysis for flexible tendon driven mechanisms

, 2010
Tendon driven mechanisms have been considered in robotic design for several decades. They provide lightweight end effectors with high dynamics. Using remote actuators it is possible to free more space for mechanics or electronics.

A Return to Normality: A Descriptive Qualitative Interview Study Exploring the Patient Experience of Gout Flare Resolution

Arthritis Care &Research, EarlyView.
Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

The validity and inter-relationship of subjective and objective measurements of stiffness in human joints [PDF]

, 1988
Rheumatoid arthritis is a chronic, progressive, inflammatory disease characterised by pain, stiffness, swelling and loss of function. Severity of these symptoms is extremely variable both between patients and over time in individual patients.
