Abstract
INTRODUCTION Elderly people with haemophilia (PwH) develop haemophilic arthropathy, pain, and reduced health-related quality of life (HR-QoL). The condition of elderly mild haemophilia patients have rarely been evaluated. This study aimed to compare joint status, pain, and HR-QoL between elderly with mild, moderate/severe haemophilia and healthy elderlies. METHODS Knee/ankle abnormalities were assessed by ultrasound (HEAD-US) and physical examination (HJHS 2.1). Pain severity and pain interference were investigated using the Brief Pain Inventory. Pressure pain thresholds (PPTs) were obtained at knees/ankles and forehead. Functional limitations were evaluated using the 2-Minute-Walking-Test, Timed-Up-and-Go and HAL. The EQ-5D-5L questionnaire evaluated HR-QoL. Healthy controls (HCs) and elderly individuals with moderate/severe and mild haemophilia were compared using Kruskal-Wallis and Mann-Whitney U tests. RESULTS From the 46 elderly PwH approached, 40 individuals (≥60 years) with haemophilia A/B (17 moderate/severe; 23 mild) and 20 age-matched HCs were recruited. Moderate/severe PwH displayed worse joint status, lower PPTs, and poorer HR-QoL than mild PwH and HCs (p-value = .010-<.001). HEAD-US abnormalities were observed in 100% of knees and 94% of ankles in moderate/severe PwH, versus 50% of knees and 61% of ankles in mild PwH. Pain was reported by 80% and 57% of moderate/severe and mild PwH, respectively. Low PPTs, functional limitations, and poor HR-QoL scores were likewise observed in some mild PwH, yet without significantly differing from HCs. CONCLUSION This study highlights poor joint/functional status, pain, and HR-QoL outcomes in elderly with moderate/severe haemophilia. A few mild haemophilia subjects presented joint abnormalities, pain, functional limitations, and poor HR-QoL, without significantly differing from HCs. HIGHLIGHTS Elderly individuals with mild haemophilia have not yet been extensively studied, whereas moderate/severe haemophilia individuals have proven to suffer from haemophilic arthropathy, pain, and poor health-related quality of life (HR-QoL). Using a case-control design, joint status, pain, and HR-QoL outcomes were examined in elderly haemophilia individuals and compared with those of healthy controls (HCs). Elderly moderate/severe haemophilia individuals exhibited worse joint status, increased joint pain sensitivity, and reduced HR-QoL compared with both mild haemophilia subjects and HCs. A subset of mild haemophilia subjects exhibited poor joint status, pain, and HR-QoL outcomes, without any differences noted when compared with HCs.

The Classification of Suspected Predominant Nociplastic Pain in People with Moderate and Severe Haemophilia: A Secondary Exploratory Study. Biomedicines 2023; 11:2479. [PMID: 37760921 PMCID: PMC10525501 DOI: 10.3390/biomedicines11092479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 08/30/2023] [Accepted: 09/01/2023] [Indexed: 09/29/2023] Open
Abstract
In people with haemophilia (PwH), joint pain is a major comorbidity that is often overlooked and under-treated. It is believed that, to ensure the most successful outcome, pain management should be tailored to the predominant pain phenotype (i.e., nociceptive, neuropathic and nociplastic). The 2021 clinical criteria and grading system for nociplastic pain, established by the International Association for the Study of Pain (IASP), emphasize the necessity of early-stage identification and predominant pain type classification. Consistent with findings in other chronic musculoskeletal pain conditions, studies suggest that a subgroup of PwH suffers from nociplastic pain, i.e., pain arising from altered nociception rather than structural damage, but this has not yet been explored in PwH. This study aimed to identify PwH with "unlikely", "possible" and "probable" nociplastic pain and investigate differences in anthropometric, demographic and clinical characteristics and psychological factors between subgroups of PwH and healthy individuals.: The IASP clinical criteria and grading system were used to classify pain types in adult men with moderate or severe haemophilia recruited from two Belgian haemophilia treatment centres. Statistical analyses were applied to study between-subgroup differences. Of 94 PwH, 80 PwH (85%) were classified with "unlikely" and 14 (15%) with "at least possible" nociplastic pain (including 5 PwH (5%) with "possible" and 9 PwH (10%) with "probable" nociplastic pain). PwH in both the "unlikely" and "at least possible" nociplastic pain groups showed significantly higher levels of unhelpful psychological factors compared to healthy individuals. Additionally, age may partially account for the observed differences in body height and psychological factors. Larger sample sizes may be needed to detect more subtle between-group differences. study confirmed the presence of nociplastic pain in haemophilia, categorising a notable subgroup as individuals who experience at least possible nociplastic pain. These exploratory insights may provide a starting point for future studies and the development of more effective and tailored pain management.

Abstract
BACKGROUND Joint pain is the hallmark of haemophilia; therefore it seems clinically rather a musculoskeletal than a bleeding disorder. Although joint pain in people with haemophilia (PwH) is a complex and multidimensional problem, pain assessment remains primarily focused on the structural evaluation of their joints. Whereas, only few data are available on the potential implication of psychophysical and psychological factors. OBJECTIVE This study aimed to perform a psychophysical pain assessment including quantitative sensory testing (QST) and an evaluation of psychological factors in a large sample of PwH, to get insight into the individuals' pain system. METHODS Ninety-nine adults (36.9 ± 13.5 years) with moderate/severe haemophilia A/B and 46 healthy controls filled in self-reported pain and psychological questionnaires and underwent a QST evaluation including static and dynamic tests. Static tests focused on the determination of thermal detection and pain thresholds and mechanical pressure pain thresholds. Dynamic tests evaluated pain facilitation and the efficacy of endogenous pain inhibition. Besides comparing PwH and healthy controls, between-subgroup differences were studied in PwH based on their pain distribution. RESULTS The study revealed increased thermal and mechanical pain sensitivity and the presence of unhelpful psychological factors such as anxiety/depression in PwH. Among the subgroups, especially PwH with widespread pain showed altered somatosensory functioning. Enhanced pain facilitation and impaired efficacy of endogenous pain inhibition in PwH could not be observed. CONCLUSION Altered somatosensory functioning and unhelpful psychological factors, appear to play an important role in the pathophysiology of pain in PwH, especially in PwH with widespread pain.

Abstract
Temporomandibular disorder (TMD) is recognized for its high prevalence, presenting characteristic signs and symptoms. Cervical spine pain is present in 70% of diagnosed TMD cases. Aim: To verify if women with TMD present changes in isometric muscle strength in the scapula elevation. Methods: This is an observational, cross-sectional study. Thirty-five women, aged 22.89±2.04 years, were divided into the TMD group (TMDG), diagnosed with TMD according to the DC/TMD, and control group (CG), with asymptomatic individuals. The volunteers accessed a online link by the smartphone in order to answer questions on personal data, the Fonseca Anamnestic Index (FAI), Neck Disability Index (NDI), and Masticatory preference. In all participants, evaluation of the force of the scapula elevation muscles was performed, using a load cell model MM-100 (Kratos® SP, Brazil). Data were analyzed descriptively using the maximum, mean, and standard deviation and a two-way ANCOVA test was applied for all variables. A significance level of 5% was considered. Results: There were no statistically significant differences between the TMDG and CG for the maximal and mean muscle strength of scapular elevation. There were statistically significant differences in FAI (p <0.001*) between the CG and the TMDG. Conclusion: Based on the results, it was not possible to confirm the hypothesis that women diagnosed with TMD present lower isometric strength during scapular elevation (right/left).

Abstract
The purpose of this narrative review is to provide a critical reflection of how analytical machine learning approaches could provide the platform to harness variability of patient presentation to enhance clinical prediction. The review includes a summary of current knowledge on the physiological adaptations present in people with spinal pain. We discuss how contemporary evidence highlights the importance of not relying on single features when characterizing patients given the variability of physiological adaptations present in people with spinal pain. The advantages and disadvantages of current analytical strategies in contemporary basic science and epidemiological research are reviewed and we consider how analytical machine learning approaches could provide the platform to harness the variability of patient presentations to enhance clinical prediction of pain persistence or recurrence. We propose that machine learning techniques can be leveraged to translate a potentially heterogeneous set of variables into clinically useful information with the potential to enhance patient management.

Abstract
STUDY DESIGN Retrospective study. PURPOSE We aimed to use motor evoked potentials (MEPs) to examine the association of electrophysiological assessment of the trapezius muscle with neck pain. OVERVIEW OF LITERATURE Previous reports on the association of neck pain with the trapezius muscle have focused on surface electromyograms and muscle oxygenation; however, to our knowledge, none of these studies included detailed data on MEPs. METHODS The study included 100 patients with cervical myelopathy who underwent surgery at the National Center for Geriatrics and Gerontology in Obu, Japan from June 2010 to March 2013. Before the surgery, neck pain was evaluated using a Visual Analog Scale (a score ≥50 indicated neck pain and a score <50 indicated no neck pain). The preoperative cross-sectional areas of the trapezius muscles were measured with cervical magnetic resonance imaging sagittal T2-weighted images. Cranial stimulation under general anesthesia was used to derive the MEPs, enabling the measurement of latency and amplitude, using preoperative MEPs of the trapezius muscles. RESULTS The MEP of the trapezius muscle in patients with neck pain had significantly shorter latencies than those in patients who did not have neck pain. However, there was no significant difference in the amplitude between patients with and without neck pain. However, this tended to be greater in patients with neck pain as compared to that in those without neck pain. The cross-sectional area of the trapezius muscle in patients with neck pain was significantly smaller than that in those who did not have neck pain. CONCLUSIONS MEPs revealed electrophysiological abnormalities of the trapezius muscles in patients with neck pain, supporting a relationship of neck pain with the trapezius muscles.

Abstract
PURPOSE The aim of this study is to determine the relationship between complaints of the neck and shoulder region, the jaw-shoulder violin fixation force, and the activity of the neck and shoulder muscles in violinists. METHODS In this case-control study twenty professional violinists were included, of which ten with current complaints of the neck shoulder region and ten without these complaints. A questionnaire including the DASH and NDI was used; violin fixation force and activity of the superficial neck muscles were evaluated in five playing conditions. RESULTS Each group consisted of eight female and two male violists with a mean age of 29 years. Violinists with complaints had more muscle activity of all evaluated muscles compared to violinists without complaints; complaints were significantly associated with the muscle activity of all evaluated muscles. Complaints were not significantly associated with the violin fixation force. The playing condition significantly predicted the violin fixation force and the activity of all muscles except the left mTP. CONCLUSIONS Violinists with complaints have more muscle activity of some superficial neck and shoulder muscles. Co-contraction is thought to play a relevant role in violinists with these complaints.
