“…Before the test, the subjects were instructed to adjust their breathing and relax while sitting for 10 min [26] and stabilizing their emotions to ensure the accuracy of experimental data collected. They took the subjective scale test first and then the subjects completed a self-rated psychological measurement twice using 100 mm Visual Analog Scales (VAS) [27]. Participants were asked to label the line with their current subjective evaluation and were evaluated on six aspects of alertness, flexibility, comfort, excitement, pain and fatigue.…”

PurposeTo reveal the physiological mechanism of the decline in cognitive function after sleep deprivation, a within-subject study was performed to assess sleep deprivation effects on phase synchronization, as revealed by wavelet phase coherence (WPCO) analysis of prefrontal tissue oxyhemoglobin signals.Materials and MethodsTwenty subjects (10 male and 10 female, 25.5 ± 3.5 years old) were recruited to participate in two tests: one without sleep deprivation (group A) and the other with 24 h of sleep deprivation (group B). Before the test, each subject underwent a subjective evaluation using visual analog scales. A cognitive task was performed by judging three random numbers. Continuous recordings of the near-infrared spectroscopy (NIRS) signals were obtained from both the left and right prefrontal lobes during rest, task, and post-task periods. The WPCO of cerebral Delta [HbO2] signals were analyzed for these three periods for both groups A and B.ResultsSix frequency intervals were defined: I: 0.6–2 Hz (cardiac activity), II: 0.145–0.6 Hz (respiratory activity), III: 0.052–0.145 Hz (myogenic activity), IV: 0.021–0.052 Hz (neurogenic activity), V: 0.0095–0.021 Hz (nitric oxide related endothelial activity) and VI: 0.005–0.0095 Hz (non-nitric oxide related endothelial activity). WPCO in intervals III (F = 5.955, p = 0.02) and V (F = 4.7, p = 0.037) was significantly lower in group B than in group A at rest. During the task period, WPCO in intervals III (F = 5.175, p = 0.029) and IV (F = 4.585, p = 0.039) was significantly lower in group B compared with group A. In the post-task recovery period, the WPCO in interval III (F = 6.125, p = 0.02) was significantly lower in group B compared with group A. Reaction time was significantly prolonged, and the accuracy rate and F1 score both declined after sleep deprivation.ConclusionsThe decline in WPCO after sleep deprivation indicates reduced phase synchronization between left and right prefrontal oxyhemoglobin oscillations, which may contribute to the diminished cognitive function.

“…Subjective assessment (the patient’s perception of hair loss severity) of the 125 first-visit patients and a comparison between the assessment results prior to and following treatment were conducted using a VAS (8,12,14–16) in which the patient’s evaluation was scored from 0 (completely dissatisfied) to 100 (completely satisfied). The VAS is a simple tool for measuring the satisfaction of the patients regarding the state of their hair loss and the effect of the treatment.…”

Female pattern hair loss (FPHL) is the most common hair loss disorder in women and it may impact on the psychological and social activities of patients, thereby reducing their quality of life (QoL). Topical minoxidil has been shown to be effective and safe in the treatment of patients with FPHL. The aim of this study was to assess the QoL of patients with FPHL and investigate whether topical minoxidil solution treatment improves the QoL of these patients. In this study, we enrolled 125 female patients aged 16–72 years to answer visual analog scale (VAS) and dermatology life quality index (DLQI) questionnaires. Of these patients, 31 were recruited for the follow-up study after 12 months of treatment with 2% minoxidil. Each index and the change in QoL prior to and following treatment were statistically analyzed. There was identified to be a correlation between clinical severity and the values of the indices in all patients. There was a statistically significant difference between the VAS and DLQI scores prior to and following treatment with 2% minoxidil. A comparison between the good responders (n=23) and the poor responders (n=8) revealed no significant difference in the improvement of VAS and DLQI scores. The QoL of the patients was severely impaired by FPHL. The DLQI and VAS used in this study were validated as useful indices for the evaluation of QoL due to their high reliability, sensitivity and simplicity. This evaluation is recommended for the management of FPHL treatment. The results of the study demonstrated that topical minoxidil improved the QoL of the patients.

“…22,23 Our study utilized two reliable self-reported measures of functioning and pain adaptation, the Roland Morris Disability Questionnaire (RMDQ) 24 and the Quadruple Visual Analog Scale (QVAS). 25 Second, research has suggested that clinically meaningful improvement requires a minimum of 30% change from baseline on pain using the QVAS, and on functioning using the RMDQ. 26 Third, Myers et al 27 recently reported that higher expectations for recovery were associated with greater functional improvement.…”

Objective: Acute low back pain (ALBP) may limit mobility and impose functional limitations in active duty military personnel. Although some manual therapies have been reported effective for ALBP in military personnel, there have been no published randomized controlled trials (RCTs) of osteopathic manipulative treatment (OMT) in the military. Furthermore, current military ALBP guidelines do not specifically include OMT. Methods: This RCT examined the efficacy of OMT in relieving ALBP and improving functioning in military personnel at Fort Lewis, Washington. Sixty-three male and female soldiers ages 18 to 35 were randomly assigned to a group receiving OMT plus usual care or a group receiving usual care only (UCO). Results: The primary outcome measures were pain on the quadruple visual analog scale, and functioning on the Roland Morris Disability Questionnaire. Outcomes were measured immediately preceding each of four treatment sessions and at four weeks post-trial. Intention to treat analysis found significantly greater post-trial improvement in 'Pain Now' for OMT compared to UCO (P50.026). Furthermore, the OMT group reported less 'Pain Now' and 'Pain Typical' at all visits (P50.025 and P50.020 respectively). Osteopathic manipulative treatment subjects also tended to achieve a clinically meaningful improvement from baseline on 'Pain at Best' sooner than the UCO subjects. With similar baseline expectations, OMT subjects reported significantly greater satisfaction with treatment and overall self-reported improvement (P,0.01). Conclusion: This study supports the effectiveness of OMT in reducing ALBP pain in active duty military personnel.
