Micromotion Phenomena at the Implant Bone Interface: A Biomechanical and Histomorphometric Study

Journal of Dental and Maxillofacial Surgery, 2018
Purpose: Excessive micromotion at the implant-bone interface may result in fibrous encapsulation instead of osseointegration of dental implants. This study quantified micromotion of implants placed in polyurethane foam and sheep tibia and tried to establish correlations with histologic parameters. Method: Dental implants (n=5) were placed in the tibiae

Influence of treadmill training in dual-task gait in people with Parkinson's Disease: a case report

Fisioterapia e Pesquisa, 2014
The loss in the automaticity of gait hinders the performance of concurrent activities - Dual Task (DT) - in individuals with Parkinson's disease (PD). One hypothesis for the negative interference of DT on gait is related to the limitation of attention ...

Medial knee cartilage is unlikely to withstand a lifetime of running without positive adaptation: a theoretical biomechanical model of failure phenomena

PeerJ, 2020
Runners on average do not have a high risk of developing knee osteoarthritis, even though running places very high loads on the knee joint. Here we used gait analysis, musculoskeletal modeling, and a discrete-element model of knee contact mechanics to estimate strains of the medial knee cartilage in walking and running in 22 young adults (age 23 ± 3 ...

Analysis of medial deviation of center of pressure after initial heel contact in forefoot varus

Journal of the Formosan Medical Association, 2016
After initial heel contact, the rearfoot everts and causes medial deviation of the center of pressure (CoP). Although rearfoot angle in single-limb stance has been associated with forefoot varus (FV) ≥ 8°, medial CoP deviation has not.

Multifunctional Photochromic Piezoionic Eutectogels Through Interfacial Nanoparticle Engineering

Advanced Functional Materials, EarlyView.
Photochromic WO3 nanoparticles enable photoresponsive piezoionics in deep eutectic solvent‐based eutectogels by coupling photoinduced electronic processes with pressure‐driven ionic transport. Interfacial nanoparticle engineering enhances ionic mobility and electromechanical output, while reversible photoactivation modulates the electrical response ...
