On-Site Laser Photobiomodulation Treatment of Crushed Muscle Due to Prolonged Pressure in Rats.

Background And Objectives: Crush injuries and prolonged pressure on muscles lead to bruises and sprains and, in most of the cases, cause distraction of the muscle and release of particles into the blood stream, causing renal and systemic complications in severe cases. Laser photobiomodulation treatment (i.e.

Photobiomodulation Triple Treatment in Peripheral Nerve Injury: Nerve and Muscle Response.

Background: Muscle preservation or decrease in muscle degeneration and progressive atrophy are major challenges in patients with severe peripheral nerve injury (PNI). Considerable interest exists in the potential therapeutic value of laser phototherapy (photobiomodulation) for restoring denervated muscle atrophy and for enhancing regeneration of severely injured peripheral nerves. As previously published, the laser phototherapy has a protective and immediate effect in PNI.

Comparison of results between chitosan hollow tube and autologous nerve graft in reconstruction of peripheral nerve defect: An experimental study.

Object: This study evaluated a chitosan tube for regeneration of the injured peripheral nerve in a rodent transected sciatic nerve model in comparison to autologous nerve graft repair.

Methods: Chitosan hollow tube was used to bridge a 10-mm gap between the proximal and distal ends in 11 rats. In the control group, an end-to-end coaptation of 10-mm long autologous nerve graft was performed in 10 rats for nerve reconstruction.

Regeneration of the transected rat sciatic nerve after suturing or adhesion with cyanoacrylate glue.

Object: Traditional treatment of transected peripheral nerves has been by suturing the nerve ends to each other. Because this approach is not widely available and is technically demanding, the authors evaluated an easier method for end-to-end anastomosis using cyanoacrylate-based glue.

Methods: The authors used a rat sciatic nerve model.

Laser phototherapy (780 nm), a new modality in treatment of long-term incomplete peripheral nerve injury: a randomized double-blind placebo-controlled study.

Objective: The authors conducted this pilot study to prospectively investigate the effectiveness of low-power laser irradiation (780 nm) in the treatment of patients suffering from incomplete peripheral nerve and brachial plexus injuries for 6 months up to several years.

Background Data: Injury of a major nerve trunk frequently results in considerable disability associated with loss of sensory and motor functions. Spontaneous recovery of long-term severe incomplete peripheral nerve injury is often unsatisfactory.

Efficacy of 780-nm laser phototherapy on peripheral nerve regeneration after neurotube reconstruction procedure (double-blind randomized study).

Objective: This pilot double-blind randomized study evaluated the efficacy of 780-nm laser phototherapy on the acceleration of axonal growth and regeneration after peripheral nerve reconstruction by polyglycolic acid (PGA) neurotube.

Background Data: The use of a guiding tube for the reconstruction of segmental loss of injured peripheral nerve has some advantages over the regular nerve grafting procedure. Experimental studies have shown that laser phototherapy is effective in influencing nerve regeneration.

Whiplash injury: is there a role for electromyographic studies?

Introduction: This retrospective study was undertaken to assess the value of carrying out baseline and follow-up electromyography (EMG) for patients with whiplash-associated disorders (WAD, grades I and II) after they had undergone rear-end car collisions, and to determine if there is any agreement with clinical and imaging (CT and MRI) findings.

Materials And Methods: We carried out a retrospective review of 330 patients seeking compensation after rear-end car collisions. The treating physician referred all patients for EMG studies in the post-injury follow-up period and for additional CT scans and MRIs.

Whiplash injury--a retrospective study on patients seeking compensation.

The purpose of this cohort study is to evaluate the objective long-term findings and the final outcome of a population suffering from whiplash-associated disorders (WAD) after rear-end car collision and claiming legal compensation. Eight hundred and sixty-six patients after whiplash injury were followed up on average 32 months post-trauma. All patients had clinical examination and radiographs performed on the day of the accident and at follow up.
