Osteoporosis is a progressive disease characterized by low bone mass and micro architectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk. The aim of this study was to compare between pulsed high-intensity Nd: YAG laser (HILT) and pulsed ultrasound (PUS) in treatment of osteoporosis in men. Fifty five male patients were participated in this study, their age between 4555 years, the patients divided randomly into three groups. Laser group (LG, n=18), ultrasound group (USG, n=18) and control group (CG, n=19). Patients in Laser and ultrasound groups received treatment for 10 weeks on the lumbar spine according to designed protocol ten minutes five times per week plus exercise program but the control group receive exercise program only. Patients in the three groups evaluated at the beginning of the study and after 10 weeks using the DXA device for measuring the bone density and the results will be compared in the three groups...

To investigate the effect of high intensity laser therapy, alone or combined with exercise on pain, health related quality of life and fall risk in male with osteopenia or osteoporosis. [Subjects and Methods] 100 male patients with osteopenia or osteoporosis participated in the study. They had T-scores ≤−1.5. Patients were randomly assigned into four groups and treated with laser plus exercise, placebo laser plus exercise, laser alone and placebo laser in groups I, II, III, and IV respectively. Laser was applied to the lower back and hip regions. Exercises included aerobic exercises, weight-bearing, flexibility, and strengthening and balance exercises. Treatment were performed 3 times/week for 12 weeks. The measured outcomes were pain, health related quality of life and fall risk. [Results] All measured outcomes were significantly decreased post-treatment in all treatment groups. Laser plus exercises showed a higher significant effect than exercises with a least significant effect in the laser group in reduction of pain and quality of life. [Conclusion] High intensity laser is an effective modality for male patients with osteopenia or osteoporosis. Laser combined with exercise is more effective than exercises or laser alone in decreasing pain, fall risk an increasing quality of life after 12 weeks of treatment.

Background Osteoporosis is a major health problem in the elderly worldwide. Aim The aim of the present study was to evaluate and compare the effect of lowfrequency pulsed electromagnetic field therapy (LFPEMFT) versus low-level laser therapy (LLLT) on bone mineral density (BMD) in osteoporotic elderly. Patients and methods A total of 60 participants with primary osteoporosis, aged 55-65 years, were randomly allocated into three groups: the LFPEMFT group (group I; n=20), the LLLT group (group II; n=20), and the control group (group III; n=20). Each treatment regimen was applied for 30 min, three times weekly for 3 months on the lumbar region. BMD was evaluated using dual-energy X-ray absorptiometry. Results There were significant increases in BMD in groups I and II, whereas there was a nonsignificant increase in group III (P<0.001, 0.001, and 0.14 for groups I, II, and III, respectively). Between groups, there were significant differences in BMD but in favor of group I (P<0.001). The mean values and percentages of change in BMD were −1.94±0.76 and 39.48%, −2.63±0.49 and 16.79%, and −3.19±0.54 and 0.79% in groups I, II, and III, respectively. Conclusion LFPEMFT and LLLT are useful therapeutic procedures to increase BMD in osteoporotic elderly. Furthermore, LFPEMFT is more effective than LLLT in increasing BMD in the elderly with primary osteoporosis.

Osteoporosis (OP) increases vertebral fragility as a result of the biomechanical effects of diminished bone structure and composition. This study has aimed to assess the effects of pulsed wave low-level laser therapy (PW LLLT) on cancellous bone strength of an ovariectomized (OVX-d) experimental rat model and a glucocorticoid-induced OP (GIOP) experimental rat model. There were four OVX-d groups and four dexamethasone-treated groups. A group of healthy rats was used for baseline evaluations. The OVX-d rats were further subdivided into the following groups: control rats with OP, OVX-d rats that received alendronate, OVX-d rats treated with PW LLLT, and OVX-d rats treated with alendronate and PW LLLT. The remaining rats received dexamethasone and were divided into four groups: control, alendronate-treated rats, laser-treated rats, and laser-treated rats with concomitant administration of alendronate. PW LLLT (890 nm, 80 Hz, 0.972 J/cm 2) was performed on the spinal processes of the T12, L1, L2, and L3 vertebras. We extracted the L1 vertebrae and submitted them to a mechanical compression test. Biomechanical test findings showed positive effects of the PW LLLT and alendronate administration on increasing bending stiffness and maximum force of the osteoporotic bones compared to the healthy group. However, laser treatment of OVA-d rats significantly increased stress high load compared to OVA-d control rats. PW LLLT preserved the cancellous (trabecular) bone of vertebra against the detrimental effects of OV-induced OP on bone strength in rats compared to control OV rats.

Our aim in this study was to evaluate the effect of low-level laser therapy (LLLT) by means of diode laser bio-stimulation compared to Teriparatide in induced osteoporosis in rats. A total of 45 adult female Egyptian albino rats were used. Rats were divided into five groups: normal control, osteoporotic control, Teriparatide (TPTD) group (T), laser group (L), and laser and teriparatide (T+L) combination group. Osteoporosis was induced by performing double ovariectomy in rats. Lower jaws and left femurs were dissected. The specimens were tested using a Computed tomography unit, scanning EM (SEM) equipped with Energy Dispersive X-Ray Analyzer, and Rat PINP ELISA Kit. The histopathologic examination of experimental rat jaws and femurs revealed changes in bone architecture among the various groups throughout the experiment. CT examination showed a noticeable difference in radiodensity between jaw and femur bones. By SEM, bones of the Normal Control (NC) group showed normal bone porosity...
Physical approach for prevention and treatment of osteoporosis
Arquivos Brasileiros de Endocrinologia & Metabologia, 2010
Osteoporosis and its consequent fractures are a major problem in public health. To complement the conventional pharmacological treatment for this metabolic disease, non-pharmacological treatment options have been developed in the last decades. Several studies demonstrate that physical exercise programs including impact exercises, specific strength training, balance and coordination training may maintain or increase spine and hip bone mineral density as well as decrease the frequency of falls among osteoporotic and osteopenic patients. Furthermore, some physical agents such as vibratory platforms, low intensity electrical stimulation, laser therapy and ultrasound show positive effects on osteoporotic tissue as well. Consequently, while planning treatment for an osteoporotic patient, non-pharmacological management options should be considered and integrated to the conventional treatment in order to maximize its effects and improve the quality of life of these patients.
Possible Role of Low Level Laser Therapy on Bone Turnover in Ovariectomized Rats
Endocrine Regulations, 2010
The aim of this study was to assess the effect of low level laser therapy (LLLT) on bone turnover markers in ovariectomized rats. Thirty adult female albino rats were used in this study and divided into three groups: Group (1); 10 sham-operated rats served as controls group (2); 10 bilateral ovariectomized rats (OVX), and group ; 10 OVX rats exposed to LLLT. LLLT was applied on the neck and shaft of femur, 5 times/week for 8 weeks. The dose applied on each point was 1000 Hertz, 5 Watts for 30 seconds with a total dose of 15 mJoule/cm 2 .At the end of the experiment, blood samples were collected and sera were separated for determination of serum calcium (Ca), inorganic phosphorus (Pi), osteocalcin and alkaline phosphatase (ALP). In addition, a 24 hour urine sample was also collected from each rat for the determination of urinary calcium, phosphorous, and deoxypyridinoline(DPD)/creatinine. Results showed significant increase in serum Ca, Pi, ALP, osteocalcin, and significant decrease in U-DPD/creatinine in LLLT exposed group as compared to the other two groups. Bone morphological results revealed increase in calcium deposition and alkaline phosphatase of femoral bones of LLLT exposed group in comparison to sham-operated and OVX rats. Using software image analysis showed increased osteoblast numbers, decreased osteoclast numbers and increased compact bone thickness in LLLT exposed group. Significant positive correlations were obtained between osteoblast numbers and serum Ca, Pi, ALP, and osteocalcin in LLLT exposed group, while a significant negative correlation was noticed with U-DPD. In conclusion, the use of LLLT was found to be effective in enhancing bone formation, decreasing bone resorption in the osteoporotic OVX rats. Further studies are necessary to investigate the effect of different parameters of LLLT as wave length, duration, and also numbers of sessions. The potential use of LLLT in postmenopausal women with osteoporosis is needed to be verified.
