NCT01577992
Multiple system atrophy (MSA) is a sporadic neurodegenerative disorder. MSA is dominated by autonomic/urogenital failure which may be associated with either Parkinsonism (MSA-P subtype) or with cerebellar ataxia (MSA-C subtype). The prognostic of this disease is bad because it ended with the patient's death few years later. No neuroprotective treatment has shown a real efficacy. 50% of patients suffering of MSA frequently experienced painful sensation. The origin of this pain is unknown. In Parkinson disease (PD) ; arguments suggest the implication of dopamine neuromediator pathway in integration and modulation of pain. Several studies suggest the existence of various influences with dopamine implication in the appearance of painful sensation and that would be inhibitory. That's why observed painful symptoms in MSA and PD could be due to a decrease of pain appearance threshold, secondary to a lost of control of sensitizes centres, to Parkinson control. It is interesting to determine if MSA as PD is responsible for a decrease of pain threshold and to characterise the levodopa effect on the patient's pain threshold. Better physiopathology knowledge of pain in MSA is necessary to improve the therapeutic care. Because the efficacy of others treatments is low, it's important to improve the research for a better comfort of patients with a better understanding, analysing and treating of the pain.
NCT07422272
Pain is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." Low-Level Laser Therapy (LLLT) has gained attention as a safe, noninvasive intervention with analgesic and anti-inflammatory effects. This study examines whether a single session of LLLT can produce immediate changes in pain threshold and pain tolerance in healthy adults, compared to a sham laser control.
NCT07407127
Aim: This study aims to compare the static endurance of cervical region muscles, pressure pain thresholds of selected muscles of the stomatognathic system, and postural characteristics in young adults with and without temporomandibular joint dysfunction (TMD). Method: A total of 60 university students aged between 18 and 25 years will be included in the study. Participants will be divided into two groups: individuals with temporomandibular joint dysfunction (TMD group, n=30) and healthy controls (control group, n=30). The static endurance of cervical flexor and extensor muscles will be assessed using standardized endurance tests. Pressure pain thresholds of the temporalis, masseter, sternocleidomastoid, and upper trapezius muscles will be measured using a pressure algometer. Postural characteristics will be evaluated using the New York Posture Analysis (NYPA).
NCT07330167
The purpose of this study is to investigate if different emotional states such as boredom and happiness could influence mechanical pain thresholds and other pain - related variables such as pain tolerance, pain intensity and pain - related negative affect.
NCT06840743
The purpose of this study is to investigate if different emotional states could influence mechanical pain thresholds and other pain - related variables such as pain tolerance, pain intensity and pain - related negative affect.
NCT07178288
This study at Hashemite University looks at how people with and without tennis elbow (AKA lateral elbow tendinopathy) feel pressure pain and how their bodies briefly "turn down" pain after a cold stimulus. Participants complete brief questionnaires (basic demographics without names, a tennis-elbow symptom form, and a physical-activity form) and then have their pressure-pain threshold (PPT) tested with a handheld device that slowly increases pressure on standard spots near the elbow and wrist; they say when it first becomes painful. To test the body's built-in anti-pain system (conditioned pain modulation, CPM), one hand is placed in ice water (the cold-pressor task) and PPT is measured again at set times (before, during, and after the cold stimulus) to see how much pain sensitivity changes and how long that change lasts. Both PPT reliability and CPM after effect are measured in this study. The study findings may help improve future assessment and treatment of musculoskeletal pain conditions.
NCT07091383
The aim of this study will be to investigate and compare the effects of static stretching exercise, Instrument Assisted Soft Tissue Mobilization (IASTM), and functional IASTM techniques on hamstring muscle shortness, pain threshold, skinfold thickness, and functional muscle strength in sedentary individuals. Fifty-one sedentary individuals between the ages of 18 and 45 who meet the inclusion criteria of Cyprus International University will be included in the study. The first group will receive static stretching exercises two days a week for four weeks; the second group will receive the IASTM technique two days a week for four weeks; and the third group will receive the functional IASTM technique, which will be applied with passive movements two days a week for four weeks. Hamstring shortness, pain threshold, skinfold thickness, and functional muscle strength will be evaluated before the treatment (BT), immediately after the treatment (AT1), two weeks after the treatment (AT2), and four weeks after the treatment (AT4).
NCT06600607
This is a randomized, double-blind, placebo-controlled within-participant crossover study in healthy male participants 18-55 years of age to assess pain tolerance during a cold pressor test. The study will be conducted at a single center in New Zealand.
NCT06836193
The purpose of this study is to investigate if different emotional states could influence mechanical pain thresholds in individuals with chronic pain.
NCT05904873
The goal of this clinical trial is to investigate whether it is possible to get a preliminary idea about the postoperative pain in the patient with the results of a practical cold press test applied to American Society of Anesthesiologists(ASA) 1 and 2, healthy, male patients aged 16-35 before extraction of the lower third molar. The main question it aims to answer are: • Can post-operative pain be predicted with an cold test that can be applied more practically than conventional quantitative sensory tests applied preoperatively? Participants will need to keep their hands on ice for 240 seconds prior to third molar surgery. When they take their hands off the ice, they will be asked to describe their pain on the visual analog scale. After the operation, the participants are required to mark whether they use painkillers every 8 hours in their pain follow-up forms and the pain they feel according to the visual analog scale. Depending on the endurance time of the participants to keep their hands on the ice; Two different groups were determined as less than 240 sec and equal to 240 sec. The pain scores and the amount of painkiller use between these two groups were compared with each other.
NCT05594511
This is a randomized, controlled, double-blind clinical trial. The main objective is to evaluate the immediate effect of the mandibular muscle-energy technique on pain, functionality and kinesiophobia in subjects suffering from temporomandibular dysfunction and bruxism. In the experimental group the jaw muscle-energy technique will be applied and in the control group a placebo technique will be applied. The intention is to see the immediate effects of the intervention and two evaluations of the pre- and post-intervention outcome variables and a follow-up of kinesiophobia one week later will be performed.
NCT04919681
The primary objective of this study is to determine the immediate efficiency of a six weeks regular stretching protocol on regional and distant pain sensitivity. It is hypothesised that regional and distant pain sensitivity will significantly decrease following six weeks of regular stretching. The secondary objective of the study is to determine the effect after four-week cessation of the stretching protocol on regional and distant pain sensitivity. If regional and distant pain sensitivity decrease following regular stretching, it is hypothesised that the analgesic effect will abate following four-week cessation.
NCT05317702
Massage is a common rehabilitation treatment for musculoskeletal pain. Prior studies indicate massage applied with a deep pressure that induces a moderate amount of pain produces a lessening of pain sensitivity compared to light touch, pain free massage. The investigators now aim to investigate how long pain sensitivity changes last after 4 minutes of moderately painful massage and determine factors that help predict who displays a lessening of pain sensitivity.
NCT03886883
This study investigates the role of two endogenous inhibitory mechanisms; exercise-induced hypoalgesia (EIH) and a conditioning painful stimulus (CPM) on passive joint range of motion, passive resistive torque and pain sensitivity. The study is a randomized, repeated-measures cross-over study.
NCT03713788
This study investigates the influence of a remote, painful stimulus on stretch tolerance. Half of the participants will receive a conditioning painful stimulus following static stretching while the other half will rest quietly.
NCT01351363
Following arthroscopic shoulder surgery a small but significant number of people suffer severe postoperative pain. This study aims to predict which patients are at risk of developing severe post operative pain so that they may be targeted with a more aggressive post operative pain regimen.
