Sol-gel dip-coated TiO nanofilms reduce heat production in titanium alloy implants produced by microwave diathermy.

To verify that the TiO nanofilm dip-coated by sol-gel can reduce titanium alloy implants (TAI)'s heat production after microwave diathermy (MD). The effect of 40 W and 60 W MD on the titanium alloy substrate coated with TiO nanofilm (Experimental Group) and the titanium alloy substrate without film (Control Group) were analyzed and . Changes in the skeletal muscle around the implant were evaluated in by histology.

Prevention of muscle atrophy in ICU patients without nerve injury by neuromuscular electrical stimulation: a randomized controlled study.

Background: Extensive muscle atrophy is a common occurrence in orthopaedics patients who are bedridden or immobilized. The incidence is higher in intensive care unit (ICU) inpatients. There is still controversy about how to use neuromuscular electrical stimulation (NMES) in ICU patients.

Study on TiO Nanofilm That Reduces the Heat Production of Titanium Alloy Implant in Microwave Irradiation and Does Not Affect Fracture Healing.

Background: Metal implants can produce heat and damage adjacent tissues under microwave irradiation, which makes local metal implants in the body a contraindication for microwave therapy. However, with the wide application of titanium alloy implants which have low permeability and low conductivity, this concept has been challenged. Our team members have confirmed through previous research that continuous low-power microwave irradiation does not cause thermal damage to the surrounding tissues of the titanium alloy.

Comparative study of the proliferative ability of skeletal muscle satellite cells under microwave irradiation in fractures with titanium alloy internal fixation in rabbits.

The aim of the present study was to investigate the proliferation of skeletal muscle satellite cells (MSCs) under different amounts of microwave irradiation in fractures with titanium alloy internal fixation. A total of 45 male New Zealand adult white rabbits were used to establish a femoral shaft fracture and titanium alloy internal fixation model. The rabbits were randomly divided into the control group (group A) and the experimental groups (groups B and C).

Enhancement of Apoptosis by Titanium Alloy Internal Fixations during Microwave Treatments for Fractures: An Animal Study.

Objective: Microwaves are used in one method of physical therapy and can increase muscle tissue temperature which is useful for improving muscle, tendon and bone injuries. In the study, we sought to determine whether titanium alloy internal fixations influence apoptosis in tissues subjected to microwave treatments at 2,450 MHz and 40 W during the healing of fractures because this issue is not yet fully understood.

Methods: In this study, titanium alloy internal fixations were used to treat 3.

Thermal effects of 2450 MHz microwave exposure near a titanium alloy plate implanted in rabbit limbs.

This study aimed to examine the safety profile of microwave therapy on limbs with metal implants. New Zealand white rabbits were implanted with titanium alloy internal fixation plates. Femurs were exposed to 20, 40, 60, or 80 W of microwave radiation for 30 min (microwave applicator at 2450 MHz), and temperatures of the implants and muscles adjacent to implants were recorded.

Carpal tunnel syndrome assessment with ultrasonography: value of inlet-to-outlet median nerve area ratio in patients versus healthy volunteers.

Objective: To evaluate the diagnostic value of the Inlet-to-outlet median nerve area ratio (IOR) in patients with clinically and electrophysiologically confirmed carpal tunnel syndrome (CTS).

Methods: Forty-six wrists in 46 consecutive patients with clinical and electrodiagnostic evidence of CTS and forty-four wrists in 44 healthy volunteers were examined with ultrasonography. The cross-sectional area (CSA) of the median nerve was measured at the carpal tunnel inlet (the level of scaphoid-pisiform) and outlet (the level of the hook of the hamate), and the IOR was calculated for each wrist.

[Design & development progress of the computer rehabilitation evaluation system].

This review paper presents the current design & development progress and challenges of computer rehabilitation evaluation system.

[Design & development of the stroke rehabilitation evaluation system].

The stroke rehabilitation evaluation system has been designed and developed in view of the present practice status of clinical rehabilitation medicine. The system not only implements patient information collection and rehabilitation evaluation, but also outputs individual rehabilitation program automatically according to evaluation outcome.

Low dose of continuous-wave microwave irradiation did not cause temperature increase in muscles tissue adjacent to titanium alloy implants--an animal study.

Background: Research studies on the influence of radiofrequency electromagnetic radiation on implants in vitro have failed to investigate temperature changes in the tissues adjacent to the implants under microwave therapy. We therefore, used a rabbit model in an effort to determine the impact of microwave therapy on temperature changes in tissues adjacent to the titanium alloy implants and the safety profile thereof.

Methods: Titanium alloy internal fixation plates were implanted in New Zealand rabbits in the middle of femur.

Effects of low-dose microwave on healing of fractures with titanium alloy internal fixation: an experimental study in a rabbit model.

Background: Microwave is a method for improving fracture repair. However, one of the contraindications for microwave treatment listed in the literature is surgically implanted metal plates in the treatment field. The reason is that the reflection of electromagnetic waves and the eddy current stimulated by microwave would increase the temperature of magnetic implants and cause heat damage in tissues.

Comparative study of microRNA profiling in keloid fibroblast and annotation of differential expressed microRNAs.

Keloids are tumor-like skin scars that grow as a result of the aberrant healing of skin injuries, with no effective treatment. The molecular mechanism underlying keloid pathogenesis is still largely unknown. In this study, we compared microRNA (miRNA) expression profiles between keloid-derived fibroblasts and normal fibroblasts (including fetal and adult dermal fibroblasts) by miRNA microarray analysis.

[Experimental study on regeneration of sciatic nerve injury with physical therapy].

Objective: Peripheral nerve injury is a common clinical disease, to study the effects of the physical therapy on the regeneration of the injured sciatic nerve, and provide a reference for clinical treatment.

Methods: Sixty-four female adult Wistar rats (weighing 252-365 g) were chosen and randomly divided into 4 groups (n = 16): group A, group B, group C, and group D. The experimental model of sciatic nerve defect was established by crushing the right sciatic nerve in groups B, C, and D; group A served as the control group without crushing.

Autografting satellite cells to repair damaged muscle induced by repeated compression: an animal model.

Background: Repeated elevation of intramuscular pressure (IMP) causes skeletal-muscles damage. The purpose of this paper was to investigate the regenerative effect of satellite cells autografted to the damaged muscle in a rabbit model.

Materials And Methods: Twenty-four adult rabbits were randomized into three groups: 1) experimental group, 2) non-graft group, and 3) control group.

Experimental study of prognosis of chronic compartment syndrome.

There is little in the literature concerning the pathobiology and repair processes of impaired skeletal muscle after decompressive operation for chronic compartment syndrome (CCS), which would be valuable for prognosis. Repeated tourniquet compression through cuff inflation on rabbits' claves was performed daily for 2 hr, then stopped for 30 min, and applied for another 2 hr. The contralateral hindlimb, which was not compressed, served as a control.

Methods: Using 10 beagles, three-foot weight-bearing canine models were made by fixing unilateral wrist joints at 90 epsilon flexionally.
