Filter by:The primary objective of this study is to determine the immediate efficiency of stretching intensity on regional and distant pain sensitivity in healthy subjects. It is hypothesized that the analgesic effect of stretching may be linked with the intensity of stretching in a dose-response relationship.
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.
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.
The association between pressure pain threshold and different aspects of low back pain has garnered attention over the years. However, since most of such studies in the past employed cross sectional designs, a longitudinal study design with follow-up measurements is required to further investigate this relationship. Studying this relationship will not only offer insights into the phenomenon of pain but may also bring us one step closer to achieving the seemingly insurmountable goal of objectively measuring back pain and its different dimensions.
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.
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.
Physical therapists frequently use spinal manipulation therapy (SMT) to treat spinal pain. However, the methods by which SMT exerts its effects are not well understood. The aim of this study is to assess potential changes in pain pressure threshold following both a cervical and lumbar spine manipulation in a single treatment session at sites local and diffuse to the site of manipulation application. This study will also attempt to determine if the order of the cervical and lumbar manipulation application impacts pain pressure threshold changes.
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.
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.
The following study is designed to determine the analgesic efficacy of smoked marijuana (0, 1.98, and 3.56% THC) and oral THC (0, 10, and 20 mg) in the Cold-Pressor Test (CPT), a laboratory model of pain which has predictive validity for clinical use of analgesics. Oral THC (dronabinol) is known to have a slower onset and longer duration of action compared with smoked marijuana. Therefore, the analgesic effects of oral THC is expected to peak later and last longer than effects produced by smoked marijuana.
