Emotions are involved in the identification of safety cues in the environment, and are also related to social interaction through recognition of emotional facial expressions. Heart rate variability (HRV) can be an indicator of the adaptive response of the autonomic nervous system to stressful conditions, including pain. This study aimed to investigate the emotional processing in a sample of patients with chronic musculoskeletal by measuring the resting-state HRV and the ability to recognize facial emotion expressions. ⋯ Participants with chronic musculoskeletal pain presented a lower vagal activity evidenced by HRV. Participants in the symptomatic group showed lower ability to recognize faces of disgust, anger, and sadness when compared to asymptomatic participants. Considering that individuals with low resting HF-HRV have difficulties with regulating their emotions, the lower vagal activity and lower ability to recognize faces of emotional expressions observed in chronic musculoskeletal pain may suggest alterations in emotional processing. This study may shed light on changes in the emotional processing and in the autonomic nervous system in this population.

Application of spatially interlaced innocuous warm and cool stimuli to the skin elicits illusory pain, known as the thermal grill illusion (TGI). This study aimed to discriminate the underlying mechanisms of central and peripheral neuropathic pain focusing on pain quality, which is considered to indicate the underlying mechanism(s) of pain. We compared pain qualities in central and peripheral neuropathic pain with reference to pain qualities of TGI-induced pain. ⋯ We found similar qualities between TGI-induced pain in healthy participants and central neuropathic pain rather than peripheral neuropathic pain. The mechanism of TGI is more similar to the mechanism of central neuropathic pain than that of neuropathic pain.

Fear-avoidance beliefs questionnaire (FABQ) is a self-report, valid and reliable questionnaire to quantify fear and avoidance beliefs related to physical activity and work. Furthermore, it can be used to predict prolong disability in patients with non-specific neck pain. Although it was originally developed to manage patients with low back pain, it has also been studied in individuals with neck pain. This questionnaire was translated into several languages following reports of potential benefits in patients with neck pain. Recently, Thai neck clinical trials, international multi-centre trials and data sharing are growing throughout the world but no validated Thai version of the FABQ is available for clinical and research uses. Our objectives were to translate and cross-culturally adapt the FABQ into Thai version and evaluate its psychometric properties in Thai patients with non-specific neck pain. ⋯ The Thai version of the FABQ for non-specific neck pain was successfully adapted. It is a valid and reliable instrument to quantify fear and avoidance beliefs among patients with non-specific neck pain who speak and read Thai.

Severe post-operative pain is common after total knee arthroplasty. Patient-controlled analgesia is an alternative method of pain management, whereby a patient administers his or her own pain medication. Patients seem to prefer this method over nurse-administered analgesia. However, it remains unclear whether patients using patient-controlled analgesia devices use higher or lower doses of opioids compared to patients treated with oral opioids. ⋯ The administration of oxycodone via intravenous patient-controlled analgesia devices does not lead to increased opioid or anti-emetic consumptions compared to nurse-administered pain medication after total knee arthroplasty. Patient-controlled analgesia might lead to shortened length of stay.

Orebro Musculoskeletal Pain Screening Questionnaire (OMPSQ) is widely used in clinical practice and for research purpose to screen the risk of chronicity in patients with Non-specific low back pain (NSLBP). The questionnaire has been cross-culturally adapted into different languages, but to date, there has not been Hausa version of the questionnaire. This study is important as the Hausa language is widely spoken across sub-Saharan Africa. The study aims to cross-culturally translate the English version of the (OMPSQ) into Hausa language (OMPSQ-H) and to test its psychometric properties in Hausa patients with NSLBP. ⋯ The OMPSQ-H was successfully translated and cross-culturally adapted with no problem of comprehension. Moreover, it has shown adequate psychometric properties in terms of internal consistency, reliability, responsiveness and constructs validity. Consequently, the OMPSQ-H can be considered as a valid tool for identifying and screening both psychosocial risk factors and risk of chronicity of NSLBP in Hausa population.
