BACKGROUND: There is conflicting evidence about what factors influence outcomes after total knee replacement (TKR). The objective is to identify baseline factors that differentiate patients who achieve both, minimal clinically important difference (MCID) and a patient acceptable symptom state (PASS) in pain and function, measured by WOMAC, after TKR from those who do not attain scores above the cutoff in either of these dimensions. METHODS: One-year prospective multicentre study...

BACKGROUND: Masticatory muscle-pain patients often complain about sensorimotor changes, but the effects of pain on the psychophysical properties remain unclear. This study aimed to investigate the effects of Delayed-Onset Muscle Soreness (DOMS) on the jaw's position sense (PS) and occlusal sensitivity (OS). METHODS: Twelve participants underwent intense concentric-eccentric jaw exercises. Self-reported muscle fatigue and pain, pain-free maximum mouth opening (MMO), pain pressure thresholds (PPTs) at right and left masseter and right and left anterior temporalis, maximum voluntary bite force (MVBF), PS, and OS were recorded before, immediately after, 24h, 48h, and one week after the exercises...

OBJECTIVES: Methods of energy delivery for traditional spinal cord stimulation (SCS) systems consist of adjusting programming parameters to affect the total charge delivered per unit time. One high electrical charge delivery method being considered is subthreshold high density (HD) programming. To date, there is limited clinical evidence for the efficacy and safety of paresthesia-free HD programming. The aim of this study was to examine the efficacy and safety of HD programming. MATERIALS AND METHODS: A retrospective review was performed on HD-programmed SCS patients with a minimum of one year follow-up...

Hyeong Cheol Moon, Young Seok Park
PURPOSE: The zona incerta (ZI) is below the ventral tier of the thalamus and has a strong influence selectively in higher-order thalamic relays. Although neuropathic pain has been suggested to result from reduced gamma-aminobutyric acid (GABA) and GABAergic signaling in the ZI, the mechanisms remain unclear. Here, the role of GABA and GABAergic signaling was investigated in the ZI in neuropathic pain using sciatic nerve chronic constriction injury (CCI) rats. MATERIALS AND METHODS: Single-unit neuronal activity was recorded, and microdialysis was performed in the ZI of CCI rats and sham-treated rats in vivo...

The forebrain somatic sensory locus for input from sensors on the surface of an active prosthesis is an important component of the Brain Machine Interface. We now review the neuronal responses to controlled cutaneous stimuli and the sensations produced by Threshold Stimulation at Microampere current levels (TMIS) in such a locus, the human thalamic Ventral Caudal nucleus (Vc). The responses of these neurons to tactile stimuli mirror those for the corresponding class of tactile mechanoreceptor fiber in the peripheral nerve, and TMIS can evoke sensations like those produced by the stimuli that optimally activate each class...

This study evaluated inter- and intra-observer reliability and discriminative validity of three movement control tests: 1) standing knee-lift test; 2) static lunge test; and 3) dynamic lunge test. Thirty-eight subjects, 21 with low-back pain and 17 healthy, were video-recorded while performing the tests. Four physical therapists scored the tests according to a standardized protocol and calculated a composite score for each test based on the number of incorrect test components. Inter-observer reliability for the composite scores ranged between 0...

The size of human social networks significantly exceeds the network that can be maintained by social grooming or touching in other primates. It has been proposed that endogenous opioid release following social laughter would provide a neurochemical pathway supporting long-term relationships in humans (Dunbar, 2012) yet this hypothesis currently lacks direct neurophysiological support. We used positron emission tomography (PET) and μ-opioid-receptor (MOR) specific ligand [11C]carfentanil to quantify laughter-induced endogenous opioid release in 12 healthy males...

REVIEW
N A Martin, S Falder
INTRODUCTION: Burn injury is common and depth is one measure of severity. Although the depth of burn injury is determined by many factors, the relationship between the temperature of the injurious agent and exposure duration, known as the time-temperature relationship, is widely accepted as one of the cornerstones of burn research. Moritz and Henriques first proposed this relationship in 1947 and their seminal work has been cited extensively. However, over the years, readers have misinterpreted their findings and incorporated misleading information about the time-temperature relationship into a wide range of industrial standards, burn prevention literature and medicolegal opinion...

We aimed to assess the impact of social support on symptoms in Brazilian women with FM. An observational, descriptive study enrolling 66 women who met the 1990 American College of Rheumatology (ACR) criteria. Social support was measured by the Social Support Survey (MOS-SSS), functionality was evaluated using the Fibromyalgia Impact Questionnaire (FIQ), depression was assessed using the Beck Depression Inventory (BDI), anxiety was measured using the Hamilton Anxiety Scale (HAS), affectivity was measured by Positive and Negative Affect Schedule (PANAS), and algometry was carried out to record pressure pain threshold (PPth) and tolerance (PPTo) at 18 points recommended by the ACR...

Dancers are often referred to as "athletes of the arts," and like other athletes they undergo years of hard physical training in pursuit of excellence. Previous research has indicated that dancers develop high pain thresholds and push past their pain barriers. This has potential implications for their health and wellbeing in both their professional careers and life after dance. Therefore, the purpose of this pilot study was to explore the perceptions and experiences of injury, pain, and retirement among professional dancers...

BACKGROUND: Diabetic peripheral neuropathy (DPN) is the most common complication of diabetes and more than half of the patients with DPN have self-reported symptoms referring to painful diabetic neuropathy (PDN). Nerve growth factor (NGF) is a key factor for the nervous system, but the role of it in the neuropathic pain of diabetic patients is unclear. OBJECTIVE: This study aimed to investigate the relationship between the dynamic expression of NGF in dorsal horn and dorsal root ganglion (DRG) of diabetic rats and hyperalgesia and allodynia in diabetic neuropathic pain...

BACKGROUND: Commonalities in the core symptoms of fatigue and cognitive dysfunction experienced by chronic fatigue syndrome (CFS, also known as ME) and multiple sclerosis (MS) patients have been described. Many CFS and MS patients also experience chronic pain, which has been attributed to central sensitization in both groups of patients. However, the characteristics of pain in CFS and MS patients have not been compared. OBJECTIVES: To compare experimental pain measurements in patients with CFS or MS and healthy controls...

BACKGROUND: The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the various symptoms and characteristics of chronic pain. Knowledge concerning changes in pain processing in LBP remains ambiguous, partly due to the diversity in the LBP population...

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) have sufficient scientific support for their use as tissue protectors. Preliminary studies suggest that their angiotensin-II type 2 receptor (AT2R)-blocking properties have a beneficial profile in the treatment of neuropathic pain. OBJECTIVES: The purpose of the current study was to quantify the extent of the somatosensory effects of ACEI and ARB in cancer patients with chemotherapy-induced peripheral neuropathy...
