Acupuncture Points and Perforating Cutaneous Vessels Identified Using Infrared Thermography: A Cross-Sectional Pilot Study.

AIMS: To evaluate the presence of perforating cutaneous vessels (PCV) in different lower limb acupuncture points (AP) using thermography. MATERIAL AND METHODS: An analytical cross-sectional study was performed on the two lower limbs (n=6) of volunteer subjects. In total, 144 AP and 144 control points (CP) were analysed, one for each AP. First, the AP and CP were located on each individual. Subsequently, both the real and thermographic images were created. In the real images, the location of the AP and the established CP were highlighted with boxes. FLIR Tools Plus and Physio Thermal Imaging software were used to merge the real image with the AP and the CP and to merge the thermographic image with the PCV. By superimposing both images, we were able to verify the presence of PCV among the AP and CP. RESULTS: PCV were identified in 87.5% of the 144 AP examined and in 18.1% of the respective CP. All the AP had a higher percentage of PCV compared to their respective CP, with statistically significant differences in all points, except for ST33 and ST34. The probability of finding PCV in AP was 11 times higher than the probability of not finding it. DISCUSSION: Thermography may serve as a useful tool in the assessment and treatment of patients using acupuncture. The presence of PCV in the area of the acupuncture needle insertion could partially influence the effects generated by the acupuncture technique from the vascular autonomic point of view. CONCLUSIONS: There is a high proportion of PCV in the AP area located in the lower limb.

Effects of an anteroposterior mobilization of the glenohumeral joint in overhead athletes with chronic shoulder pain: A randomized controlled trial.

BACKGROUND: Passive oscillatory mobilizations are often employed by physiotherapists to reduce shoulder pain and increase function. However, there is little data about the neurophysiological effects of these mobilizations. OBJECTIVES: To investigate the initial effects of an anteroposterior (AP) shoulder joint mobilization on measures of pain and function in overhead athletes with chronic shoulder pain. DESIGN: Double-blind, controlled, within-subject, repeated-measures design. METHOD: Thirty-one overhead athletes with chronic shoulder pain participated. The effects of a 9-min, AP mobilization of the glenohumeral joint were compared with manual contact and no-contact interventions. Self-reported pain, pressure pain threshold (PPT), range of movement (ROM), muscle strength, and disability were measured immediately before and after each intervention. RESULTS/FINDINGS: No significant differences were found among the treatment conditions in any of the variables investigated. A significantly greater mean decrease in self-reported shoulder pain was observed following treatment condition [0.63 (0.12, 1.14); p = 0.01]. PPT at the affected shoulder increased significantly following both the treatment [0.23 (-0.43, 0.02); p = 0.02] and manual contact [0.28 (-0.51, 0.04); p = 0.01] conditions. Shoulder AP joint mobilization also increased PPT at a distal, non-painful site [0.42 (-0.85, 0.01); p = 0.04]. No changes were observed in shoulder ROM or muscle strength. CONCLUSIONS: This study found no superior effects in various pain or function-related outcome measures of a passive oscillatory anteroposterior mobilization applied to the glenohumeral joint compared to manual contact and no-contact interventions in overhead athletes with chronic shoulder pain. Some ability to modulate shoulder pain and local and widespread pain sensitivity was observed in the short term after the passive oscillatory anteroposterior mobilization.

Immediate effects of thoracic spinal mobilisation on erector spinae muscle activity and pain in patients with thoracic spine pain: a preliminary randomised controlled trial.

OBJECTIVES: To investigate the activity of the thoracic erector spinae muscles and perceived pain intensity immediately after central postero-anterior (PA) mobilisation of the thoracic spine. DESIGN: Randomised, placebo-controlled, experimental design. PARTICIPANTS AND INTERVENTIONS: Thirty-four participants with non-specific thoracic pain were randomised to the experimental group [grade III central PA mobilisation performed for 3minutes at the level of the seventh thoracic vertebra (T7)] or the placebo group (less than grade I central PA mobilisation performed for 3minutes at T7). MAIN OUTCOME MEASURES: Before and immediately after PA mobilisation, surface electromyography (EMG) was recorded from the thoracic erector spinae muscles as the participants performed 10° spine extension from a prone position for 10seconds. Each participant rated their pain intensity as an investigator performed grade III central PA over the most symptomatic thoracic segment, and the pressure pain threshold (PPT) was evaluated bilaterally over the erector spinae muscles. RESULTS: The EMG amplitude of thoracic erector spinae activity was reduced significantly after the intervention in the experimental group (P<0.05), but not in the placebo group. The difference between the groups was significant {pre-post change: placebo -14 [standard deviation (SD) 50]mV, experimental 28 (SD 48)mV; mean difference -42mV; 95% confidence interval of the difference -76 to 7; P<0.05} albeit small (Grissom=0.44). However, both groups showed a significant reduction in pain immediately after the intervention, and both groups showed a similar pre-post change in PPT. CONCLUSION: These preliminary findings indicate that grade III central mobilisation over the most symptomatic thoracic segment reduces thoracic erector spinae activity during extension of the trunk in people with non-specific thoracic spine pain.

Low power laser stimulation of the bone consolidation in tibial fractures of rats: a radiologic and histopathological analysis.

The objective of this study is to analyze the effectiveness of low power laser irradiation in the bone consolidation of tibial fractures in rats. An experimental, comparative, prospective study with control group was designed. Twenty Wistar rats were grouped into control (n = 10) and experimental groups (n = 10). A tibial fracture, with a mechanical drill, was inflicted in all rats. The experimental group received ten days of low power arsenide-gallium laser irradiation of 850 nm (KLD, Sao Paulo, Brasil)-100 mW, 8 J/cm(2), 64 s. Before and after the laser treatment, a radiologic analysis was carried out in both groups, in which the rats were graded from 0 to IV according the Montoya scale of bone consolidation. Also, we histopathologically analyzed the bone to estimate the proliferation of fibroblasts, bone matrix, and angiogénesis with a microscopy, which were graded as I (thin layer of fibroblasts and osteoid matrix), II (thick layer of fibroblasts and osteoid matrix), or III (thick layer of fibroblasts and osteoid matrix and new blood vessels). Radiologic data showed that the experimental group had a higher bone consolidation of Montoya scale after ten days of laser irradiation compared to control group (P < 0.004). Histopathologic data showed more fibroblasts and angiogenesis presence in the group receiving laser irradiation, compared to control group (P < .002). The low power laser radiation therapy may expedite the bone repair after tibial fractures in rats, according to radiologic and histopathologic analysis.
