Introduction: The purpose of the study was to compare pain ratings and thresholds in men women before after isometric contractions varying intensity duration performed with elbow flexor muscles. Methods: Pain perception assessed, using a pressure device applied contralateral finger, following contractions: 1) three brief maximal voluntary (MVC), 2) 25% MVC sustained until task failure, 3) for 2 min, 4) 80% failure. Results: High-intensity long-duration, low-intensity produced an analgesic...

Introduction Conditioned pain modulation (CPM) is the concept that inhibits and has potential rehabilitation implications for exercise prescription. The purpose of this study was to determine whether changes in pressure perception after a thermal conditioning stimulus (i.e., CPM) attenuated with aging CPM predicted relief (exercise-induced hypoalgesia (EIH)) healthy young older adults. Methods Twenty (21.9 ± 3.3 yr, 10 men) 19 (72.0 4.5 adults participated three sessions: one familiarization...

Whether there is a gender difference in fatigue and recovery from maximal velocity fatiguing contractions across muscles not understood.Sixteen men 19 women performed 90 isotonic at voluntary shortening (maximal concentric contractions, MVCC) with the elbow flexor knee extensor (separate days) load equivalent to 20% isometric contraction (MVIC).Power (from MVCCs) decreased similarly for both (P > 0.05). Men had similar declines MVIC of flexors, but greater reductions force electromyogram...

Spinal activation of the cAMP pathway produces mechanical hyperalgesia, sensitizes nociceptive spinal neurons, and phosphorylates transcription factor cAMP-responsive element binding protein (CREB), which initiates gene transcription. This study examined role in a model chronic muscle pain by assessing associated behavioral changes phosphorylation CREB. Bilateral hyperalgesia paw was induced administering two injections acidic saline, 5 d apart, into gastrocnemius male Sprague Dawley rats....

ore competencies in pain man-agement for prelicensure health professional education were recently established.1 These represent the expec-tation of minimal capabilities graduating care students management and include 4 domains: multidimensional nature pain, assessment measure-ment, con-text (Appendix 1).The pur-pose this article is to advocate identify how core can be applied pro-fessional (entry-level) physical thera-pist curriculum.By ensuring that manage-ment are embedded within...

Abstract Objective Physically active individuals show greater conditioned pain modulation (CPM) compared with less individuals. Understanding the effects of acute exercise on CPM may allow for a more targeted use in management pain. This study investigated isometric CPM. In addition, between-session and within-session reliability was investigated. Design Experimental, randomized crossover study. Setting Laboratory at Marquette University. Subjects Thirty healthy adults (19.3±1.5 years, 15...

Abstract Reduced heart rate variability (HRV) and fatigue are common after COVID‐19 infection both potentially influenced by physical activity (PA). We compared resting HRV, PA from accelerometers questionnaires, self‐reported in 41 survivors (~8 months postinfection, 38 ± 17 years) with matched controls. Differences HRV were observed on acceleration capacity ( p = 0.041), deceleration 0.032), high‐frequency peak frequency 0.019), absolute low‐frequency power 0.042), relative very 0.012),...

Introduction This study assessed the effect of isometric contractions that varied in intensity and duration on pain perception adults older than 60 yr. Methods Pain was measured 24 men women (mean ± SD age = 72.2 6.2 yr) using a pressure device applied to right index finger before after left elbow flexor muscles following doses: 1) three brief maximal voluntary (MVC), 2) 25% MVC held for 2 min, 3) task failure. Results Older reported increased thresholds (58 s vs 49 s, P < 0.001) decreased...

Abstract Background Exercise causes an acute decrease in the pain sensitivity known as exercise‐induced hypoalgesia ( EIH ), but specificity to certain modalities remains unknown. This study aimed compare effect of isometric exercise on heat and pressure sensitivity. Methods On three different days, 20 healthy young men performed two submaximal knee extensions (30% maximal voluntary contraction 3 min) a control condition (quiet rest). Before immediately after rest, was assessed randomized...

Pain relief after exercise, exercise-induced hypoalgesia (EIH), is established across the lifespan. Conditioned pain modulation (CPM: inhibits pain) may be a mechanism for EIH.In 55 adolescents, pressure thresholds were measured before and exercise (deltoid, quadriceps, nail bed) during CPM at bed deltoid test stimulus sites. The relationship between EIH was explored.EIH occurred quadriceps; deltoid. correlated deltoid; adolescents with greater experienced exercise. At this site, predicted...

Background Muscle fatigability can increase when a stressful, cognitively demanding task is imposed during low-force fatiguing contraction with the arm muscles, especially in women. Whether this occurs among older adults (> 60 years) currently unknown. Questions/purposes We aimed to determine if higher cognitive demands, stratified by sex, increased years). Secondarily, we assessed varying demand resulted decreased steadiness and was explained anxiety or cortisol levels. Methods Seventeen...

Pain reports are greater with increasing weight status, and exercise can reduce pain perception. It is unknown, however, whether relieve in adolescents of varying status. The purpose this study was to determine across status report relief after high-intensity aerobic (exercise-induced hypoalgesia (EIH)).Sixty-two (15.1 ± 1.8 yr, 29 males) participated the following three sessions: 1) pressure thresholds (PPT) before quiet rest, clinical (McGill Questionnaire), physical activity levels...

There is a wide continuum of conditioned pain modulation (CPM) in adults with older experiencing an attenuated CPM response compared younger adults. Less known for adolescents and the role anthropometrics.Fifty-six (15.1 ± 1.8 years; 32 normal weight 24 overweight/obese; 27 boys) completed session that included anthropometric testing. Pressure thresholds were measured at nailbed deltoid muscle (test stimuli) foot submerged cool or ice water bath (conditioning stimulus). Weight status, body...

This eye tracking study contributes novel findings of age-associated changes in movements during the commonly used pegboard tests manual dexterity, including a greater number corrective saccades and lesser time gazing at holes older compared with young adults. An association between attentional deficits dexterity impairments adults is also highlighted. Results shed light on potential mechanisms underlying well-documented motor
