OBJECTIVE: To evaluate the patient-reported expectations regarding cannabis for pain following musculoskeletal (MSK) trauma and patients\' perceptions and attitudes regarding its use.
METHODS:
METHODS: A cross-sectional retrospective survey-based study.
METHODS: Three orthopaedic clinics in Ontario (Level-1 trauma center, Level-2 trauma center, rehabilitation clinic).
UNASSIGNED: Adult patients presenting to the clinics from January 24, 2018, to March 7, 2018, with traumatic MSK injuries (fractures/dislocations and muscle/tendon/ligament injury) were administered an anonymous questionnaire on cannabis for MSK pain.
UNASSIGNED: Primary outcome measure was the patients\' perceived effect of cannabis on MSK pain, reported on a continuous pain scale (0%-100%, 0 being no pain, and 100 unbearable pain). Secondary outcomes included preferences, such as administration route, distribution method, timing, and barriers (lack of knowledge, concerns for side effects/addiction, moral/religious opposition, etc.) regarding cannabis use.
RESULTS: In total, 440 patients were included in this study, 217 (49.3%) of whom were female and 222 (50.5%) were male, with a mean age of 45.6 years (range 18-92 years, standard deviations 15.6). Patients estimated that cannabis could treat 56.5% (95% CI 54.0%-59.0%) of their pain and replace 46.2% (95% CI 42.8%-49.6%) of their current analgesics. Nearly one-third (131/430, 30.5%) reported that they had used medical cannabis and more than one-quarter (123/430, 28.6%) used it in the previous year. Most felt that cannabis may be beneficial to treat pain (304/334, 91.0%) and reduce opioid use (293/331, 88.5%). Not considering using cannabis for their injury (132/350, 37.7%) was the most common reason for not discussing cannabis with physicians. Higher reported pain severity (β = 0.2/point, 95% CI 0.1-0.3, P = 0.005) and previous medical cannabis use were associated with higher perceived pain reduction (β = 11.1, 95% CI 5.4-16.8, P < 0.001).
CONCLUSIONS: One in 3 orthopaedic trauma patients used medical cannabis. Patients considered cannabis could potentially be an effective option for managing traumatic MSK pain and believed that cannabis could reduce opioid usage following acute musculoskeletal trauma. These data will help inform clinicians discussing medical cannabis usage with orthopaedic trauma patients moving forward.

The procedure with the highest rate of opioid prescription in plastic surgery is abdominoplasty. Additionally, plastic surgery patients are at a particularly elevated risk of becoming opioid-dependent. The main objective of this study was to perform a systematic review and create an algorithm for a multimodal pain regimen specific to patients undergoing abdominoplasty. A systematic search of the research literature was performed to summarize the prevailing understanding of multimodal pain control in the management of abdominoplasty. The initial search yielded 448 articles. Sixty-eight manuscripts were identified for full-text review. The effectiveness of current strategies was evaluated by way of pain scores, opioid usage, and length of stay, as well as other measures of physical function such as time to early mobilization. In 32 studies involving 2451 patients, the efficacy of different pain regimens during abdominoplasty was evaluated. Among nontraditional, opioid-sparing analgesia, efficacy of treatment interventions for improved pain and decreased opioid usage was found inall studies. Among local infusion studies, efficacy of treatment interventions for improved pain and decreased opioid usage was found in 78% of studies. Last, among regional block studies, efficacy of treatment interventions for improved pain was found in 87%, with 73% efficacy for decreased opioid usage. Multimodal pain regimens in abdominoplasty have the potential to play an important role in opioid-sparing practices in medicine by incorporating nonopioid pain adjuvants such as nonsteroidal anti-inflammatory drugs and transversus abdominis plane blocks in the preoperative, perioperative, and postoperative periods.
METHODS:

OBJECTIVE: To assess the influence of unilateral open disc repositioning surgery (ODRS) of the temporomandibular joint (TMJ) on the internal derangement (ID) of the contralateral joint.
METHODS: Patients with bilateral ID of TMJ who underwent unilateral ODRS were enrolled and followed-up for one year. They were divided into two groups based on the contralateral disease: the anterior disc displacement with reduction (ADDWR) and without reduction (ADDWoR). Postoperative evaluation included clinical and MRI evaluation. Indices measured were unilateral intermaxillary distance (UID), visual analogue scale (VAS), disc length (DL), condylar height (CH), and disc-condyle angle (DCA). Paired t tests were used to compare the clinical and MRI indices between different time points.
RESULTS: Ninety-six patients were enrolled, including 47 in the ADDWR group and 49 in the ADDWoR group. One-year post-surgery, ODRS led to significant increases in MMO, DL, and CH, and decrease in VAS and DCA on the operated side (P < 0.05). In ADDWR group, UID, DL, and CH increased significantly, and VAS decreased (P < 0.05), with no significant change in DCA (P > 0.05). In ADDWoR group, clinical and MRI variables worsened slightly, except for UID, which remained unchanged (P > 0.05).
CONCLUSIONS: ODRS is a promising method for correcting TMJ ID and may improve condition of ADDWR and decrease progress of ADDWoR at the contralateral joint. Preoperative bilateral TMJ evaluation is essential for better outcomes.
CONCLUSIONS: ODRS can effectively treat TMJ ID and produce adaptive changes in the contralateral ID, for which continuous monitoring of the contralateral joint is essential.

UNASSIGNED: The effect of transcutaneous electrical nerve stimulation (TENS) on pain and impression of change was assessed during a 2.5-hour intervention on the first postoperative days following hip surgery in a randomized, single-blinded, placebo-controlled trial involving 30 patients.
UNASSIGNED: Mixed-frequency TENS (2 Hz/80 Hz) was administered using specially designed pants integrating modular textile electrodes to facilitate stimulation both at rest and during activity. The treatment outcome was assessed by self-reported pain Numerical Rating Scale (NRS) and Patient Global Impression of Change (PGIC) scores at four time points. The ability to perform a 3-meter walk test and the use of analgesics were also evaluated. Group comparison and repeated-measure analysis were carried out using nonparametric statistics.
UNASSIGNED: The active TENS group exhibited significantly higher PGIC scores after 30 minutes, which persisted throughout the intervention (all p ≤ 0.001). A reduction in NRS appeared after one hour of active TENS, persisting throughout the intervention (all p ≤ 0.05). The median group differences in pain ratings were greater than the minimum clinically important difference, and the analysis of pain trajectories confirmed clinical significance at the individual level. Moreover, patients in the active TENS group were more likely able to perform a 3-meter walk test by the end of the intervention (p = 0.04). Analysis of the opioid-sparing effect of TENS was inconclusive (p = 0.066). No postoperative surgical complications or TENS-related side effects were observed during the study.
UNASSIGNED: Mixed-frequency TENS integrated in pants could potentially be an interesting addition to the arsenal of treatments for multimodal analgesia following hip surgery. This trial is registered with NCT05678101.

Chronic low back pain (LBP) is very common, resulting in functional deficits and significant socio-economic burden. Non-pharmacological treatments, such as physical-psychological therapy, are frequently utilized. Vojta therapy (VT) is a type of physical therapy that effectively enhances the automatic control of body posture. This study aimed to evaluate the effects of combining VT with the usual standard of care (USC) therapy on psychometric and functional parameters in patients with chronic LBP. A total of 148 patients diagnosed with chronic LBP were recruited and randomized into two groups: LBP-VT (n = 82) and LBP-USC (n = 66). Patients were assessed for demographic characteristics, comorbid conditions, clinical findings, health status, pain symptom scales, psychometric, and functional parameters. The LBP-VT group received VT in addition to USC and electrotherapy, while the LBP-USC group received only USC. Initial Hamilton Depression Scale assessments indicated moderate depression, which improved to mild depression post-treatment. The effect of the treatment on self-esteem was significant for the LBP-VT group and moderate for the LBP-USC group. Functional parameters improved in both groups, with the LBP-VT group having significantly better results. Combining VT with standard care, electrotherapy, and massage significantly improved posture, reduced depression associated with functional deficits, and enhanced self-esteem in patients with chronic LBP.

BACKGROUND: The effectiveness of telemedicine in aiding rehabilitation exercises among patients with rotator cuff (RC) disorders remains unknown. Therefore, this meta-analysis aimed to assess the effectiveness of telemedicine in patients with RC disorders.
METHODS: Randomized clinical trials (RCTs) on the effectiveness of telemedicine in patients with RC disorders were summarized through a meta-analysis. A systematic search for these RCTs was conducted in PubMed, Cochrane, Embase, and Web of Science databases up to July 2024. Statistical analysis was performed using Stata 16. Publication bias was estimated with the funnel plot and Egger\'s test.
RESULTS: Ten studies involving 497 participants (telemedicine group = 248 and conventional group = 249) were enrolled, with follow-up durations ranging from 8 weeks to 48 weeks. Functional outcomes measured by the Constant-Murley score were markedly improved after treatment in the telemedicine group compared to the conventional group. Moreover, compared to conventional treatment, telemedicine significantly improved shoulder function evaluated by Quick Disabilities of the Arm, Shoulder, and Hand Score, relieved pain assessed by visual analog scale pain score, and improved range of motion after treatment and in the final follow-up period.
CONCLUSIONS: Telemedicine has demonstrated potential in alleviating pain and enhancing shoulder function and motion in patients with RC injuries. It may be a feasible intervention for rehabilitation exercises. Further research with a large sample size and standardized treatment is warranted to validate these findings.

Infectious disease pathogenesis is still a complex field to study. The course of several clinical signs, such as allodynia and pain, may be observed in domestic animals. However, the knowledge of their pathways and correct treatment need controlled experiments, many of them using laboratory animals. Measuring changes in mechanical thresholds of the hind paw and viscera is a useful technique to observe changes in pain perception in rodents. Withdrawal response can be measured first in baseline tests, which creates better control of experimental groups. Subsequent tests can be performed after inducing infection and adding drugs to the protocol. The use of an electronic von Frey apparatus associated with the use of a facial scale to observe pain-like changes allows a simple, precise, and consistent assessment to evaluate allodynia and pain in mice. Thus, experiments using the present methodology for Trypanosoma evansi infection represent a useful method to evaluate allodynia and pain in laboratory-infected animals, which can be applied to the conventional treatment for livestock animals.

OBJECTIVE: This study analyzed, using an umbrella review, existing systematic reviews on medications to prevent and control postoperative endodontic pain to guide professionals in choosing the most effective drug.
METHODS: An electronic search in the PubMed (MEDLINE), LILACS, SciELO, EMBASE, Scopus, Web of Science, Cochrane Reviews, and Data Archiving and Networked Services (DANS) databases retrieved 17 systematic reviews. The study included only systematic reviews of clinical trials with or without meta-analyses evaluating effectiveness of medications in reducing pain after non-surgical endodontic treatment.
RESULTS: The evidence showed that steroidal and non-steroidal anti-inflammatory drugs and opioids effectively controlled pain within six to 24 h.
CONCLUSIONS: Dexamethasone, prednisolone, paracetamol, and mainly ibuprofen provided higher postoperative pain relief. The quality of evidence of the reviews ranged from very low to high, and the risk of bias from low to high, suggesting the need for well-designed clinical trials to provide confirmatory evidence.
CONCLUSIONS: This review emphasizes the efficacy of developing protocols for pain control after endodontic therapy.

UNASSIGNED: Long head of biceps brachii tendinopathy, a frequent source of anterior shoulder pain, may lead to discomfort and diminished function. The objective of this study is to assess the efficacy of dry needling and transcutaneous electrical nerve stimulation in these patients.
UNASSIGNED: Thirty patients were randomized into dry needling and transcutaneous electrical nerve stimulation groups and assessed before treatment, 8 and 15 days after treatment using a visual analogue scale, shoulder pain and disability index, pressure pain threshold, tissue hardness, and biceps peritendinous effusion.
UNASSIGNED: Both treatments significantly reduced the visual analogue scale in immediate (p < 0.001), short-term (p < 0.01), and medium-term effects (p < 0.01). Dry needling outperformed transcutaneous electrical nerve stimulation for the pain (p < 0.01) and disability (p < 0.03) subscales of the shoulder pain and disability index in the short-term and medium-term effects, respectively. Pressure pain threshold increased after both treatments but didn\'t last beyond 8 days. Neither treatment showed any improvements in tissue hardness of the long head of biceps brachii muscle. Notably, only the dry needling group significantly reduced biceps peritendinous effusion in both short-term and medium-term effects (p < 0.01).
UNASSIGNED: Dry needling showed non-inferior results to transcutaneous electrical nerve stimulation in reducing pain and disability and demonstrated even superior results in reducing biceps peritendinous effusion (see Graphical Abstract).
UNASSIGNED: The Institutional Review Board of the China Medical University Hospital (CMUH107-REC2-101) approved this study, and it was registered with Identifier NCT03639454 on ClinicalTrials.gov.
Both dry needling and transcutaneous electrical nerve stimulation effectively reduced pain in the long head of biceps brachii tendinopathy.Dry needling outperformed transcutaneous electrical nerve stimulation in short-term and medium-term pain and disability relief, respectively.Dry needling demonstrated superior results in reducing biceps peritendinous effusion compared to transcutaneous electrical nerve stimulation.

<b>Introduction:</b> Previous studies indicate a significant role of the inflammatory response in the etiopathogenesis of peripheral artery disease (PAD) and chronic pain (CP).<b>Aim:</b> The aim of the study was to determine the relationship between the concentration of SP and the level/concentration of inflammatory mediators (pro-inflammatory cytokines, positive and negative acute phase protein, anti-inflammatory cytokines) and pain intensity in people suffering from chronic pain (CP) in the course of PAD.<b>Material and methods:</b> We examined 187 patients of the Department of Vascular Surgery. As many as 92 patients with PAD and CP (study group) were compared to 95 patients with PAD without CP (control group). The relationship between SP and the level/concentration of fibrinogen, C-reactive protein (CRP), antithrombin III (AT), serum albumin, interleukin 10 (IL-10), tumor necrosis factor alpha (TNF-α) and pain intensity (Numeric Rating Scale; NRS) was analyzed. Statistical analysis was performed using the R program, assuming the level of statistical significance of α = 0.05.<b>Results:</b> Patients with CP had significantly higher levels of fibrinogen (P < 0.001), CRP (P < 0.001), SP (P < 0.001), IL-10 (P < 0.001), and lower serum albumin levels (P < 0.023). Higher SP concentration was associated with higher levels of IL-10, CRP, and pain intensity. In both groups, SP concentration correlated negatively with the level of fibrinogen (P < 0.001) as well as with albumin in the control group (P < 0.001).<b>Conclusions:</b> Thus, there is a relationship between the concentration of SP and fibrinogen, along with CRP, IL-10, and the intensity of pain in people suffering from CP in the course of PAD, and the level of albumin in the group without CP.
