The aim of this study was to investigate the effect of low-level laser therapy (LLLT) on pain relief and functional performance in patients with chronic knee osteoarthritis (OA). Forty patients with knee OA were randomly assigned into active laser group (n?=?20) and placebo laser group (n?=?20). The LLLT device used was a Ga-As diode laser with a power output of 50 mW, a wavelength of 850 nm, and a diameter beam of 1 mm. Eight points were irradiated and received dosage of 6 J/point for 60 s, with a total dosage of 48 J/cm(2) in each session. The placebo group was identical but treated without emission of energy. LLLT was applied two times per week over the period of 4 weeks. Outcome measurements included pain intensity at rest and at movement on visual analog scale, knee function using Western Ontario McMaster Universities Osteoarthritis Index scale, and ambulation duration. These measurements were collected at baseline and post-intervention. The results showed significant improvements in all assessment parameters in both groups compared to baseline. Active laser group showed significant differences in pain intensity at rest and movement, knee function, and ambulation duration when compared with the placebo group. Therefore, LLLT seemed to be an effective modality for short-term pain relief and function improvement in patients with chronic knee OA. HubMed – rehab

Scores on the Safe Functional Motion test predict incident vertebral compression fracture.

The Safe Functional Motion test (SFM) was developed to document movement strategies used to perform everyday activities that may increase the risk for osteoporotic fracture. After adjusting for variables known to predict vertebral compression fracture (VCF), baseline score on the SFM was a significant independent predictor of incident VCF at 1- and 3-year follow-ups.Functional movements may contribute to risk for VCF. We hypothesize that scores on the SFM, a performance-based test of physical function, are associated with incident VCF.An osteoporosis clinic database was queried for men and women ?50 years with an initial SFM and corresponding data for prevalent VCF, history of injurious falls, femoral neck bone mineral density (fnBMD), osteoporosis medication use, and incident morphometric VCF at 1-year (n?=?878) and 3-year follow-ups (n?=?503). Multiple logistic regressions, adjusted for gender, age, injurious fall(s), fnBMD, prevalent VCF at baseline, and osteoporosis medication use, were used to determine whether SFM score was associated with incident VCF at follow-up visits.Baseline SFM score was a significant independent predictor of incident VCF at 1-year follow-up (adjusted odds ratio (95 % confidence intervals (CI))?=?0.818 (0.707, 0.948); p?HubMed – rehab
