Evaluation of Endogenous Pain Modulation Mechanisms With Transcutaneous Electrical Nerve Stimulation...
Chronic PainA number of chronic pain conditions are characterized by imbalances in excitatory and/or inhibitory mechanisms and these deficits appear correlated with the response to certain treatments. Evaluating these mechanisms among people who suffer from chronic pain could allow clinicians to adapt the treatment to each patient according to the deficits observed. To evaluate excitatory and inhibitory mechanisms, a thermode (hot plate) and a cold water bath can be used (standardized protocol). Unfortunately, these tools are expensive, time-consuming and require complex equipment and software. As such, it is not realistic for clinicians to use them for routine patient assessment. A potential alternative to study these mechanisms is TENS (transcutaneous electrical nerve stimulation). TENS is frequently used in rehabilitation and unlike thermode and cold water bath, is affordable, easy to use and requires very little time and equipment. The objective of this study are to determine if the TENS can replace the thermode and cold water bath (standardized protocol) for the evaluation of excitatory and inhibitory mechanisms. Also, to determine if there will be a correlation with the standardized protocol. 50 healthy participants between 18 and 60 years old will participate in this study. Each participant will attend two experimental sessions. In one of the two sessions, the evaluation will be done with the TENS; in the other session, the evaluation will be done with the standardized protocol (thermode and cold water bath).

Effects of COVID-19 in Chronic Pain
Chronic PainCovid19The aim of this study is to evaluate the effects of the COVID-19 pandemic on pain, stress, sleep and quality of life in patients with chronic musculoskeletal pain and the relationships between them. In this cross-sectional study, 100 volunteer patients aged 18-65 years with chronic (longer than 3 months) musculoskeletal pain were included. Age, gender, body-mass index (BMI) and systemic diseases of the participants were recorded as demographic data. Data were collected regarding the area of the body where pain is most dominant in the musculoskeletal system and how long the pain has been in these area, whether there is routine use of analgesics before and after the pandemic and the amount if any, whether the person or the person's relatives have a history of COVID-19, whether exercising regularly before and after the pandemic. Afterwards, the participants were asked to evaluate their general pain severity and global well-being assesment with the visual analog scale (VAS) in the pre-pandemic period and in the last month. For pain severity, the patients marked their pain severity on a line of 10 centimeters (cm) with the starting point (0) expressing no pain, and the end point (10) expressing the most severe pain experienced in life; for patient's global assesment the patients marked their global assesment on a line of 10 centimeters (cm) with the starting point (0) expressing very good, and the end point (10) expressing very bad. The distance between the point marked by the patient and the starting point was measured. The higher the measured value meant the greater the severity of the patient's pain and the worse the patient's global assessment [11]. Subsequently, the patients were asked to answer questions on the Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI) and Nottingham Health Profile (NHP) scales.
Research Protocol for Karuna Labs Inc.: Safety and Efficacy of Virtual Reality Graded Motor Imagery...
Chronic PainLow Back Pain7 moreThe purpose of this study is to investigate, in two phases: (1) the feasibility and safety of Virtual Embodiment Therapy in treating chronic pain of lower back and upper limbs and (2) the efficacy of Virtual Embodiment Therapy on chronic pain disorders of the lower back and upper limbs. In phase 1, we will investigate the feasibility, safety, and side effects related to this treatment by assessing simulator sickness. In phase 2, which in contingent on successful completion of phase 1, we will assess symptoms of pain specific to the region treated, fear and avoidance behavior, and depression symptoms before and after 8 sessions of treatment with Virtual Embodiment Therapy in order to assess efficacy. This study will be single-blinded, because the participation of the clinician is necessary to ensure proper administration of the therapy, as well as to monitor in the event of adverse reactions.
Does Pecs II Block Reduce the Incidence of Post Mastectomy Pain Syndrome (PMPS)? A Cross Sectional...
Chronic PainPost mastectomy pain syndrome (PMPS) is a chronic pain condition that develops after breast cancer surgery. The objective of this study was to determine if Pecs II block administered prior to general anesthesia (GA) reduced the incidence of PMPS after mastectomy and axillary clearance (MAC) when compared with conventional analgesic therapy.
