Objective Oxidative stress plays an important role in neuropathic pain. Spinal manipulative therapy (SMT) can exert beneficial effects in pain outcomes in humans and animal models. SMT can also modulate oxidative stress markers in both humans and animals. We aimed to determine the effect of Impulse®-assisted SMT (ISMT) on nociception and oxidative...
Article
p38 and Akt plays an important role in neuropathic pain. p38 appears to regulate the SVCT-2 expression, a specific transporter for ascorbic acid (an important antioxidant and neuromodulator). Vitamins C and E induce antinociception and appear to affect p38, Akt, and SVCT-2, but it is unknown their effect on these molecules in spinal cord of rats wi...

Objective: The purpose of our study was to evaluate the effect of manually assisted lumbar spinal manipulation therapy on tactile allodynia, peripheral nerve functional recovery, and oxidative markers in rats exposed to knee immobilization-inducing hypersensitivity. Methods: Tactile allodynia and sciatic, tibial, and peroneal functional indices...

Manually assisted lumbar spinal manipulation therapy (MASMT) induces analgesia, but it is still poorly understood the mechanisms behind of its effect. Our study evaluated the effect of three weeks of MASMT on tactile allodynia, peripheral nerve functional recovery, and oxidative markers in rats exposed to knee immobilization for four weeks, a condi...

Vitamin E (vit. E) and vitamin C (vit. C) are antioxidants that inhibit nociception. The effect of these vitamins on oxidative-stress markers in the spinal cord of rats with chronic constriction injury (CCI) of the sciatic nerve is unknown. This study investigated the effect of intraperitoneal administration of vit. E (15 mg·kg-1·day-1) and vit. C...

N-acetylcysteine (NAC) inhibits nociceptive transmission. This effect has been associated partly with its antioxidant properties. However, the effect of NAC on the levels of lipid hydroperoxides (a pro-oxidant marker), content of ascorbic acid (a key antioxidant molecule of nervous tissue) and total antioxidant capacity (TAC) is unknown. Thus, our...

Objective: Evaluate the effect of lumbar spine manipulation (LSM) using a manually operated chiropractic adjusting instrument with adapter (AAI-4) on sciatic, tibial and peroneal functional indices (FIs) and mechanical threshold in a model of knee-joint immobilization (KI).
Article
Full-text available
We determined the effect of N-acetylcysteine (NAC) on the expression of the phosphorylated p38 (p-p38) protein and superoxide anion generation (SAG), two important players in the processing of neuropathic pain, in the lumbosacral spinal cord of rats with chronic constriction injury (CCI)-induced neuropathic pain. The sciatic functional index (SFI)...
Article
Antioxidants have been tested to treat neuropathic pain, and α-Tocopherol (vitamin E - vit. E) and ascorbic acid (vitaminC - vit. C) are potent antioxidants. We assessed the effect of intraperitoneal administration of vit. C (30mg/kg/day) and vit. E (15mg/kg/day), given alone or in combination, on the mechanical and thermal thresholds and the sciat...

The purpose of this study was to investigate oxidative-stress parameters in individuals with chronic neck or back pain after 5 weeks of treatment with high-velocity, low-amplitude (HVLA) spinal manipulation. Twenty-three individuals aged 38.2 ± 11.7 years with nonspecific chronic neck or back pain verified by the Brazilian Portuguese version of the...

This study was designed to assess the peak force of a manually operated chiropractic adjusting instrument, the Activator Adjusting Instrument 4 (AAI 4), with an adapter for use in animals, which has a 3- to 4-fold smaller contact surface area than the original rubber tip. Peak force was determined by thrusting the AAI 4 with the adapter or the orig...
Article
Since N-acetylcysteine (NAC) is a donor of cysteine, we studied the relationship between NAC and concentration of oxidized and reduced glutathione (GSH/GSSG ratio), and glutathione peroxidase (GPx) and glutathione-S-transferase (GST) activities in the lumbosacral spinal cord of rats with chronic constriction injury (CCI) of the sciatic nerve that r...

This study examined the interferential current (IC) acute effect on mechanical pain threshold (MPT), eccentric peak torque (EPT) and creatine kinase (CK) activity after delayed onset muscle soreness (DOMS) induction by eccentric exercise in human quadriceps. Forty-one physically active healthy male volunteers aged 18-33 years were randomly assigned...
Article
Although reactive oxygen species (ROS) are involved in neuropathic pain, the direct relationship between these species and chronic constriction of sciatic nerve (CCI) has not been studied in spinal cord. Thus, this study induced CCI in rats and these animals were sacrificed 3 and 10 days after the surgical procedure to determine the superoxide dism...
Article
This study investigates the analgesic effect of high-velocity, low-amplitude (HVLA) manipulation and antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx) in erythrocytes of men with neck pain. Twenty-two men with neck pain of mechanical origin who were aged 20 to 50 years, were nonsmokers, had a sedentary lifestyle, had n...

This study was undertaken to examine the acute effect of interferential current on mechanical pain threshold and isometric peak torque after delayed onset muscle soreness induction in human hamstrings. Forty-one physically active healthy male volunteers aged 18-33 years were randomly assigned to one of two experimental groups: interferential curren...
Article
Aquatic organisms are continuously exposed to environmental variations, which can lead to physiological and biochemical alterations. Leporinus macrocephalus, known as piavuçu, is a migratory species that may be exposed to variations in dissolved oxygen levels. Studies evaluating oxidative changes undergone by this species in these conditions are sc...
Article
The aim of this study was to identify the influence of high-velocity, low-amplitude (HVLA) manipulation on lipid peroxidation and catalase activity in subjects with neck pain who answered the Neck Disability Index and quadruple visual scale questionnaires. Twenty-two men (mean age, 38 years) with neck pain were recruited through radio and newspaper...
