“…It is important to emphasize that not all chronic pain populations consistently demonstrate an impaired EIH response and different measures have been used to quantify EIH (eg, clinical pain intensity vs pressure pain threshold) that may influence both the underlying mechanism and observed response to exercise. Although limited to a few studies, impaired EIH has also been observed in painful diabetic neuropathy 66 and chronic neck pain, 18 whereas a normal EIH response has been observed in those with rheumatoid arthritis 37, 88 and chronic low back pain. 96 Furthermore, in contrast with the findings of Burrows et al, 15 Kosek et al 73 observed intact local and global EIH in individuals with end-stage hip and knee OA.…”

“…96 Furthermore, in contrast with the findings of Burrows et al, 15 Kosek et al 73 observed intact local and global EIH in individuals with end-stage hip and knee OA. Impaired EIH has been observed after repeated shoulder movements in people with whiplash-associated disorder (WAD), 18 whereas a normal EIH response was seen after an isometric leg muscle contraction. 119 In contrast, impaired EIH is typically, 56,119,147 observed in patients with WAD after aerobic exercise, highlighting the variability of the EIH response in chronic pain populations and suggesting a possible difference in EIH according to the type of exercise and pain condition.…”

Exercise is considered an important component of effective chronic pain management and it is well-established that long-term exercise training provides pain relief. In healthy, pain-free populations, a single bout of aerobic or resistance exercise typically leads to exercise-induced hypoalgesia (EIH), a generalized reduction in pain and pain sensitivity that occurs during exercise and for some time afterward. In contrast, EIH is more variable in chronic pain populations and is more frequently impaired; with pain and pain sensitivity decreasing, remaining unchanged or, in some cases, even increasing in response to exercise. Pain exacerbation with exercise may be a major barrier to adherence, precipitating a cycle of physical inactivity that can lead to long-term worsening of both pain and disability. To optimize the therapeutic benefits of exercise, it is important to understand how EIH works, why it may be impaired in some people with chronic pain, and how this should be addressed in clinical practice. In this article, we provide an overview of EIH across different chronic pain conditions. We discuss possible biological mechanisms of EIH and the potential influence of sex and psychosocial factors, both in pain-free adults and, where possible, in individuals with chronic pain. The clinical implications of impaired EIH are discussed and recommendations are made for future research, including further exploration of individual differences in EIH, the relationship between exercise dose and EIH, the efficacy of combined treatments and the use of alternative measures to quantify EIH. Perspective: This article provides a contemporary review of the acute effects of exercise on pain and pain sensitivity, including in people with chronic pain conditions.

“…Only two studies 8,43 classified patients into groups of different levels of pain and disability. Nine studies investigated patients with localized neck pain 7,8,11,12,36,56,72,78,81 , while ten studies investigated patients with concurrent pain in other body regions such as upper limbs 30,43,51,54,63,65,76,77,82,90 . The other studies did not describe if patients had concurrent pain.…”

This systematic review and meta-analysis examined the evidence for altered central pain processing in people with non-traumatic neck pain and the relationship between central pain processing, demographics and pain-related characteristics. Case-control studies reporting measures of altered central pain processing using quantitative sensory testing were reviewed. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) between people with non-traumatic neck pain and controls were calculated. Meta-analysis was performed using random-effects models when appropriate. Associations between SMDs with demographics and pain-related characteristics were explored on a study level using meta-regression. Twenty-six studies were eligible with 25 included for meta-analysis. Meta-analysis demonstrated mechanical hyperalgesia at remote non-painful sites in the full sample [sample size (n)=1305, SMD=-0.68] and in the subgroup with moderate/severe disability [n=165, SMD=-0.86] (moderate-quality evidence). Meta-regression indicated that remote mechanical hyperalgesia was negatively associated with age (R 2 =25.4%, P=0.031). Very-low-to low-quality evidence of remote cold and heat hyperalgesia and dysfunctional conditioned pain modulation were identified. This review suggests that altered central pain processing is present in people with non-traumatic neck pain and may be associated with disability levels and age.

“…Subjects with neck pain have less muscle strength and activity than healthy people [8,9]. Pain sensitivity and axioscapular muscle activity have altered in neck pain patients compared with healthy controls [10]. Researchers have shown a relationship between decreased muscle strength and endurance with chronic nonspecific neck pain [11].…”

Chronic neck pain is a common human health problem. Changes in scapular posture and alteration of muscle activation patterns of scapulothoracic muscles are cited as potential risk factors for neck pain. The purpose of this study was to compare the effects of neck exercise training (NET) with and without scapular stabilization training (SST) on pain intensity, the scapula downward rotation index (SDRI), forward head angle (FHA) and neck range of motion (ROM) in patients with chronic neck pain and scapular dyskinesia. A total of sixty-six subjects with chronic neck pain and scapular dyskinesia were randomly divided into three groups: neck exercise training, n = 24, combined training (NET + SST), n = 24 and a control group, n = 24. Pain intensity, SDRI, FHA and ROM were measured by the numerical rating scale, caliper, photogrammetry and IMU sensor, respectively. When the combined intervention group consisting of NET and SST was compared with NET alone at six weeks, there was a statistically significant difference in pain intensity, SDRI, FHA and cervical ROM for flexion and extension (p ≤ 0.05). Adding scapular exercises to neck exercises had a more significant effect in decreasing pain intensity, SDRI, FHA and increased cervical ROM than neck exercises alone in patients with chronic neck pain. These findings indicate that focus on the scapular posture in the rehabilitation of chronic neck pain effectively improves the symptoms.
