Effect of a home-based exercise program on functional mobility and quality of life in elderly people: protocol of a single-blind, randomized controlled trial.

Background: Elderly people have high rates of functional decline, which compromises independence, self-confidence, and quality of life (QoL). Physical exercise leads to significant improvements in strength, balance, functional mobility, and QoL, but there is still reduced access to this therapeutic strategy due to difficulties in locomotion to training centers or lack of adaptation to the exercise environment.

Methods/design: The purpose of this clinical trial will be to verify the effect of a progressive and semi-supervised, home-based exercise program on the functional mobility, and in the QoL of sedentary elderly people.

The effect of low-level laser therapy (660 nm) on the gene expression involved in tissue repair.

The effect of low-level laser therapy (LLLT) on the healing of skin lesions has been evaluated in many studies; however, the molecular mechanisms involved in the biostimulatory effects resulting from this treatment need to be better understood.

Effects of whole body vibration on bone mineral density in postmenopausal women: a systematic review and meta-analysis.

Unlabelled: This systematic review and meta-analysis of randomized controlled trials (RCTs) identified significant effects of whole body vibration (WBV) on bone mineral density (BMD) of the lumbar spine (in the sensitivity analysis and seven subgroup analyses), femoral neck (in one subgroup analysis), and trochanter (four subgroup analyses) in postmenopausal women, but not other measurements of BMD.

Introduction: Interventions using WBV training have been conducted in postmenopausal women, aimed at increasing BMD; however, the results are contradictory. Our objective is to conduct a systematic review and meta-analysis of RCTs examining WBV effect on BMD.
