Simple geometrical analysis for mechanizing the ankle joint stretching treatment procedure of a PT using a numerical calculation

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
In this paper, to mechanize a human ankle joint stretching treatment that is mainly performed by a PT (Physical Therapist), the geometrical relationships among the Ankle joint, Hip joint, Sole, and pushing device rotation center are analyzed using a ...

Learning a Shared Model for Motorized Prosthetic Joints to Predict Ankle-Joint Motion [PDF]

arXiv, 2021
Control strategies for active prostheses or orthoses use sensor inputs to recognize the user's locomotive intention and generate corresponding control commands for producing the desired locomotion. In this paper, we propose a learning-based shared model for predicting ankle-joint motion for different locomotion modes like level-ground walking, stair ...

Gouty arthritis of the spine in a renal transplant patient : a clinical case report: an unusual presentation of a common disease [PDF]

, 2015
Axial gout is a well-documented but uncommon manifestation of gout. Its mimicking nature and the impracticality of axial joint aspiration might considerably delay its diagnosis.

Assessing the Ankle Joint Line Level Before and After Total Ankle Arthroplasty With the “Joint Line Height Ratio”

Foot & Ankle Orthopaedics, 2019
Background: Restoring the joint line is an important principle in total knee arthroplasty. However, the effect of joint line level on patient outcomes after total ankle arthroplasty (TAA) remains unclear, as there is no established method for measuring ...

Biarticular mechanisms of the gastrocnemii muscles enhance ankle mechanical power and work during running

Royal Society Open Science, 2023
The objective of the study was to explore how biarticular mechanisms of the gastrocnemii muscles may provide an important energy source for power and work at the ankle joint with increasing running speed.

Neuropathic midfoot deformity: Associations with ankle and subtalar joint motion [PDF]

, 2013
BACKGROUND: Neuropathic deformities impair foot and ankle joint mobility, often leading to abnormal stresses and impact forces. The purpose of our study was to determine differences in radiographic measures of hind foot alignment and ankle joint and ...

Knee and Ankle Joint Angles Influence the Plantarflexion Torque of the Gastrocnemius

Journal of Clinical Medicine Research, 2015
Background The gastrocnemius (GA) is the lone bi-articular muscle of the leg, crossing both the knee and ankle. As with any bi-articular muscle, both joints affect its length/tension curve.

Unveiling the role of melatonin‐related gene CSNK1D in osteoclastogenesis and its implications for osteoporosis treatment

Experimental Physiology
Osteoporosis (OP) is a prevalent bone disease characterized by reduced bone density and quality, increasing fragility and fracture risk. Osteoclast (OC) activity and circadian rhythm play a role in the pathogenesis of OP.

Ankle Joints Are Beneficial When Optimizing Supported Real-world Bipedal Robot Gaits [PDF]

arXiv, 2021
Legged robots promise higher versatility and the ability to traverse much more difficult terrains than their wheeled counterparts. Even though the use of legged robots have increased drastically in the last few years, they are still not close to the performance seen from legged animals in nature.
