“…Black et al [8] examined a healthy study group and recorded that post-exercise (stress arousal) blood pressure was associated with a generalized inhibitory pain mechanism. In contrast and concerning in women presenting FM, Wentz et al [9] found that aerobic submaximal ergometer exercise test resulted in an increase in pain from the test in terms of 12 points on a Visual Analog Scale (VAS) (ranging from 1-100) [10].…”

Objective: The aim of the present analysis was to examine physiological adaptation to a sub-maximal test by measuring blood pressure (BPR) from the perspective of the fibromyalgia (FM) pain experience.Method: Twenty-four women presenting FM and twenty-six healthy women were education-and age-matched. In their homes, all women completed questionnaires regarding background and health related quality of life (SF-36).All the women performed a stepwise load increment submaximal exercise test on a cycle ergometer to the severe perceived exertion level. Blood pressure was recorded before, during and after the test.Result: Women presenting FM showed higher baseline resting systolic BPR (SBPR) and diastolic BPR (DBPR) with higher SBPR and DBPR during the recovery phase. In both groups SBPR and DBPR were correlated at base line. Women presenting FM contrasted to healthy women by BPR measures more frequently correlating during workload. In women with FM the correlative relationship between the SBPR and DBPR during recovery was pronouncedly higher. Clinical pain correlated four times more often with BPR measures in the FM study group as compared to the group of controls. In FM higher clinical pain was linked to lower BPR. Conclusion:In the context of the FM condition, the tests depict a physiologically perseverative pattern concerning SBPR and SBPR measurements. This pattern was pronounced during recovery. A higher level of clinical pain BP corresponded to lower SBPR and SBPR before and after the test confirming an inverse relationship between blood pressure and pain sensitivity in the condition of FM. Parallel, in FM the analgesic effect from BPR was insufficient due to lowered pain thresholds. Pain thresholds linked to dysregulated sympathetic and parasympathetic functions together with psychological functioning and higher levels of brain functioning need further examination.

“…Sensitivity to blunt pressure was pronounced immediately after inger trigger exercises 1cm above the medial epicondyle and 1 cm under the medial epicondyle but not at other locations. We were surprised that there were no signi icant reductions in pressure pain thresholds in the experimental at any other location or time point [14], although participants commented that they believed that they were more sensitive to pressure stimuli on the experimental arm. The failure to detect statistically signi icant differences may be due in part to between-participant variability in the distribution of pain increasing between-participant variance pressure pain thresholds at each location.…”

Background: Experimentally-induced delayed-onset muscle soreness of large muscle groups is frequently used in as an injurious model of muscle pain. We wanted to develop an experimental model of DOMS to to mimic overuse injuries from sports where repeated fi nger fl exion activity is vital such as rock climbing. The aim of this pilot study was to evaluate the utility of a 'fi nger trigger device' to induce DOMS in the fi ngers, hands, wrists and lower arms.Methods: A convenient sample of six participants completed an experiment in which they undertook fi nger exercises to exhaustion after which measurements of pain, skin sensitivity to fi ne touch, forearm circumference and grip strength in the hand, wrist and forearm were taken from the experimental and contralateral nonexercised (control) arms. Results:Pain intensity was greater in the experimental arm at rest and on movement when compared with the control arm up to 24 hours after exercise, although the location of pain varied between participants. Pressure pain threshold was signifi cantly lower in the experimental arm compared with the control arm immediately after exercises locations close to the medial epicondyle but not at other locations. There were no statistical signifi cant differences between affected and non-affected limbs for mechanical detection threshold, forearm circumference or grip strength. Conclusion:Repetitive fi nger fl exion exercises of the index fi nger by pulling a trigger against a resistance can induced DOMS. We are currently undertaking a more detailed characterization of sensory and motor changes following repetitive fi nger fl exion activity using a larger sample.

“…In a recent study, Sacramento et al 35 demonstrated that children had lower PPTs in the shoulder girdle than healthy adults. Researchers [8][9][10] have shown that exercise may induce hypoalgesia, yet the amount of exposure to the exercise that is necessary to affect pain perception is not clear. Furthermore, an exploratory analysis revealed no correlation between scapular kinematics and PPT.…”

“…[5][6][7] Exercise-induced hypoalgesia has been demonstrated in some studies. [8][9][10][11] Recently, Stolzman and Bement 11 suggested that exercise may induce hypoalgesia in adolescents. If so, young swimmers may be more tolerant of pain when accomplishing their swimming tasks and predisposed to developing shoulder injuries due to overuse, as changes in upper limb mechanics may occur.…”

Context Whereas alterations in scapular kinematics, scapulothoracic muscle activity, and pain sensitivity have been described in adult swimmers, no researchers have examined these outcomes in young swimmers. Objectives To compare scapular kinematics, scapulothoracic muscle activation, and the pressure-pain threshold (PPT) of the shoulder muscles among young nonpractitioners (those who were not involved in sports involving the upper limbs), amateur swimmers, and competitive swimmers. Design Cross-sectional study. Setting Laboratory. Patients or Other Participants A total of 90 individuals (age = 11.63 ± 0.61 years) in 3 groups: nonpractitioners, amateur swimmers, and competitive swimmers. Intervention(s) Scapular kinematics and activity of the upper trapezius, lower trapezius, and serratus anterior (SA) were measured during upper extremity elevation in the scapular plane. The PPT was assessed in the upper trapezius, infraspinatus, supraspinatus, middle deltoid, and tibialis anterior. Main Outcome Measure(s) Scapular kinematics, scapulothoracic muscle activation, and PPT. We conducted a 2-way mixed-model analysis of variance and a 1-way analysis of variance for scapular rotation and PPT, respectively. A Kruskal-Wallis test was used to assess muscle activity. The α level was set at .05. Results Competitive swimmers presented more internal rotation at 90° (P = .03) and 120° (P = .047) and more anterior tilt at 90° (P = .03) than nonpractitioners. Amateur swimmers demonstrated more anterior tilt at 90° (P = .004) and 120° (P = .005) than nonpractitioners. Competitive swimmers had greater SA activation in the intervals from 60° to 90° (P = .02) and 90° to 120° (P = .01) than amateur swimmers. They also displayed more SA activation in the interval from 90° to 120° than nonpractitioners (P = .04). No differences were found in any of the muscles for the PPT (P > .05). Conclusions Young competitive swimmers presented alterations in scapular kinematics and scapulothoracic muscle activation during upper extremity elevation that may be due to sport practice. Mechanical pain sensitivity was not altered in young swimmers.
