Abstract
Recently, fluorescence-based optical techniques have emerged as a powerful tool to probe information in the mammalian brain. However, tissue heterogeneities prevent clear imaging of deep neuron bodies due to light scattering. While several up-to-date approaches based on ballistic light allow to retrieve information at shallow depths inside the brain, non-invasive localization and functional imaging at depth still remains a challenge. It was recently shown that functional signals from time-varying fluorescent emitters located behind scattering samples could be retrieved by using a matrix factorization algorithm. Here we show that the seemingly information-less, low-contrast fluorescent speckle patterns recovered by the algorithm can be used to locate each individual emitter, even in the presence of background fluorescence. We test our approach by imaging the temporal activity of large groups of fluorescent sources behind different scattering phantoms mimicking biological tissues, and through a brain slice with a thickness of ∼200 µm.

Abstract
[Purpose] The aim of this research was to see how ultrasound and nerve gliding with and without shock wave therapy effects on clinical and sonographic data of patients with carpal tunnel syndrome (CTS). [Participants and Methods] Forty four patients with moderate carpal tunnel syndrome participated in this research. One group got shock-wave therapy in addition to median nerve glide exercises and ultrasound, whereas the other group received median nerve glide exercises and ultrasound alone. Hand grip strength (HGS), pinch grip strength (PGS), Visual Analogue Scale (VAS)-pain, Boston Questionnaire (BQ), and Cross-sectional area (CSA) of median nerve were examined before and after 10 sessions of treatment. [Results] HGS, PGS, VAS, BQ and CSA of median nerve improved considerably after therapy. [Conclusion] Patients with moderate CTS who received ultrasound and median nerve glide exercises with and without shock-wave therapy improved considerably without preference of adding shock-wave therapy to other treatment.

Abstract
BACKGROUND It is unknown how diaphragm training combined with electrical stimulation affects pain, function, static stability, and balance in athletes with chronic low back pain (CLBP). This study aimed to explore the effects of combining diaphragm training with electrical stimulation on pain, function, static stability, and dynamic balance in athletes with nonspecific CLBP. METHODS The design was a randomized clinical trial. A total of 24 amateur athletes (12 women, 12 men, mean age: 35.2 ± 9.8) with nonspecific CLBP were randomly allocated into two groups. The experimental group (n = 12) received diaphragm training plus Transcutaneous Electrical Nerve Stimulation (TENS), while the control group (n = 12) received TENS alone. Both groups underwent 12 sessions over a four-week period. Static stability, dynamic balance, pain, and function were measured pre- and post-intervention. RESULTS Analysis of variance 2 × 2 revealed greater improvements in pain (p < 0.001), static stability (p < 0.001), and dynamic balance (p < 0.01) in the experimental group compared to the control group. Function was improved in both groups following the interventions (p < 0.001), and there was a trend of a larger improvement in the experimental group than the control group (p = 0.09). Fisher's exact test showed that the experimental group reported ≥50% improvement only in the pain score, not function, compared to the group that received TENS alone (p = 0.005). CONCLUSIONS Pain, function, static stability, and dynamic balance were improved in both groups following 12 intervention sessions. However, pain, static stability, and dynamic balance were improved to a greater extent in diaphragm training plus TENS than TENS alone in amateur athletes with CLBP. Therefore, it seems beneficial to add diaphragm training to the rehabilitation program for athletes with nonspecific CLBP. TRIAL REGISTRATION The trial was retrospectively registered in the Iranian Registry of Clinical Trials ( www.irct.ir ) on September 10, 2020 as IRCT20090228001719N8 .

Abstract
Objective The purpose of this study was to compare immediate and short-term effects of combining dray needling (DN) + patient education vs ischemic compression (IC) + patient education for treating myofascial trigger points (MTP) in office workers with neck pain. Methods This was a single-blinded, randomized trial. Thirty-two participants were randomly assigned to either DN + patient education or IC + patient education group. Both groups received 2 treatment sessions with a 48-hour time interval. Pain intensity, cervical range of motion, Neck Disability Index, and satisfaction were measured. Results Pain intensity and neck disability level decreased, whereas the cervical range of motion (side-bending and rotation) increased in both groups. Analysis of variance revealed a significant interaction of group × treatment only for pain intensity, indicating a greater reduction in the IC group. Satisfaction generally increased in the follow-up assessment in both groups. Conclusion Both intervention groups had some positive immediate and short-term effects after 2 treatment sessions. However, IC + patient education was more effective than DN + patient education in the treatment of MTPs in office workers with neck pain.

Abstract
A novel mesoporous silica with enhanced phosphonic functional groups (PFGs) and without any silane agents was provided by Sol-Gel technique for selective adsorption of U(VI) from aqueous solutions (AqS). The absorbent was synthesized based on the achieving the four best performance characteristics including availability, economically, adsorption efficiency, and selectivity which are undoubtedly defined the usefulness of the adsorbents. The sorption results exhibited the highest uranium adsorption capacity, qe, of 820.7 mg/g at pH ≈ 8 which indicated the adsorbent is the best alternative for uranium adsorption from the nearly neutral solutions such as seawater. The recovery percentages by the adsorbent in the aqueous environments involving other elements such as Mg, Cd, Hg, As, Ca, Na, Ni and the salty environment with high concentration of Cl- ions are indicated that the adsorbent presents the acceptable selectivity for uranium adsorption from the AqS such as industrial wastewater. Several activities and factors including removing the silane agents, using sodium metasilicate as an available and low-cost source of silica, and using the Sol-gel method as an unexpansive synthesis technique caused to reduce the synthesis costs from 222.787 EUR/kg for the template method to 60.078 EUR/kg for Sol-gel method which confirm the synthesis of a cost-effective adsorbent.

Abstract
[Purpose] The purpose of this study was to determine the effect of dry needling on tendon-pulley architecture, pain and hand function in patients with trigger finger. [Participants and Methods] A randomized controlled trial was conducted. Fifty eight patients having trigger finger were randomly assigned as either an experimental group that received a single session of dry needling over pulleyA1 and flexor tendon or a control group that received no intervention. Thickness of tendon-pulley, and pain-hand function (by disability arm-shoulder questionnaire score and pinch grip strength) were measured by a blinded assessor before and one week after intervention. [Results] The two way mixed ANOVA in the experimental group showed that the thickness of pulley-tendon decreased, pinch grip power increased and DASH questionnaire score was decreased in comparison to the control group. [Conclusion] This study results suggest that a single session of Dry Needling (DN) was effective in decreasing pain, DASH score, pulley-tendon thickness and improving pinch grip power in patients with trigger finger.

Abstract
BACKGROUND Little is known about the neuromuscular morphometric characteristics in patients with sciatica. OBJECTIVE To evaluate the possible changes of nerve and muscle structures in patients with low back pain with unilateral radiculopathy due to lumbar disc herniation by ultrasound imaging. DESIGN A case-control observational study. METHODS Forty individuals were divided into case (n = 20; low back pain with unilateral radiculopathy due to disc herniation), and healthy control groups (n = 20). The thickness of lumbar multifidus at L5 level, and of lower limb muscles (i.e., biceps femoris, medial gastrocnemius, and soleus) was measured during both rest and full contraction to calculate the rest/contraction ratio of these muscles. Additionally, the sciatic nerve cross-sectional area and the echogenicity of the nerve and muscles were measured based on ultrasound imaging. The association between severity of low back pain radiculopathy (i.e., pain and patients' perceived disability) and rest/contraction ratio was assessed. RESULTS Patients with sciatica showed sciatic nerve enlargement, and different contraction ratios for multifidus (at L5)/ankle plantar flexors compared to the controls. The rest/contraction ratio for biceps femoris was similar between the two groups. CONCLUSION According to these findings, ultrasound imaging can be considered a useful tool to detect changes in the sciatic nerve and muscles due to disc herniation. Furthermore, regarding the observation of significant changes in muscle rest/contraction ratio in the multifidus and gastrosoleus, one might attribute these changes to the nerve root compression.

[Purpose] This study was conducted to investigate the immediate prophylactic effects of
local vibration on quadriceps muscle fatigue in young non-athletic males. [Participants
and Methods] Thirty healthy young males were randomly assigned to vibration and sham
control groups. Participants in the local vibration group received a single session
vibration (2 minutes, 30 Hz). They also in the control group received a 2-minute
vibration, while the vibration system was off. MVC, RMS and median frequency of EMG
findings and time to reach fatigue were measured. [Results] Time to reach fatigue and MVC
in the local vibration group was significantly high than those in the sham control group.
[Conclusion] It seems that the prior local muscle vibration may be useful to attenuate
some signs and symptoms of muscle fatigue.

Abstract
Background Ultrasound imaging has been suggested for studying the structure and function of nerves and muscles; however, reliability studies are limited to support the usage. The main aim of this study was to explore the intrarater within-session reliability of evaluating the sciatic nerve and some related muscles morphology by ultrasound imaging. Methods Three B-mode images from two scans (transverse and longitudinal) were acquired from the multifidus, biceps femoris, soleus and medial gastrocnemius muscles bilaterally from 15 participants with sciatica and 15 controls in one session, 1-h apart. The data were collected from March to July 2017. Contraction ratio was measured only by longitudinal scan, while the echo intensity was measured using maximum rectangular region of interest in two scans (transverse and longitudinal) for all muscles. Cross-sectional area, direct (tracing) and indirect (ellipsoid formula) methods were used to measure the sciatic nerve. Intraclass correlation coefficient (ICC 3,1), standard error of measurement and minimal detectable change were calculated. Results Good to high ICCs (0.80–0.96) were found for muscle contraction ratio in the longitudinal scans in all the muscles in both sciatica and control groups. For echo intensity measurements ICCs ranged from moderate to high, with higher ICCs seen with the maximum region of interest in the transverse scans. The minimal detectable change values ranged between 0.11 and 0.53 cm for contraction ratio. Conclusions Ultrasound imaging has high intrarater within-session reliability for assessing the sciatic nerve Cross-sectional area and muscle contraction ratios. Transverse scans with the maximum region of interest result in higher reliability. The sciatic Cross-sectional area is most accurately measured utilizing the direct tracing method rather than the indirect ellipsoid method.

Abstract
BACKGROUND Lateral scapular slide test (LSST) quantitatively measures the distance between thoracic spine (T7) and inferior angle of scapula. OBJECTIVE In this study, the intra-rater reliability, inter-rater reliability and diagnostic accuracy of LSST were measured using a caliper. METHODS Three measurements of each test position were obtained bilaterally. Intraclass correlation coefficient (ICC) (2.1), 95% CI and 2 SEMs were calculated for intra-rater and inter-rater reliability of the absolute scapular distance. Sensitivity, specificity, positive and negative likelihood ratios were determined. RESULTS 27 people with and 30 people without shoulder pain participated. The mean age (SD) for the participant was 47.7 (11.6) years and 33.5 (11.7) years, respectively. The ICCs for intra-rater reliability were high. A range of poor to good ICCs was found for inter-rater reliability. The 2 SEMs ranged from 4.6 to 7.9 mm for intra-rater reliability and from 6.8 to 13.4 mm for inter-rater reliability for people with shoulder pain. Positive and negative likelihood ratios from 0.94 to 1.22 and from 0.21 to 2.5, respectively, were demonstrated. CONCLUSION SST did not show a consistent high reliability. The diagnostic accuracy of the LSST was low, which questions the clinical importance of the tests outcomes.
