- OBJECTIVE: The present study assessed somatosensory changes related to trigeminal nerve damage using extensive evaluation tools and assessed the effect of such damage on the patients' psychosocial status and quality of life compared with healthy participants.METHODS: In 37 patients with intraorally or extraorally presenting trigeminal nerve damage diagnosed as painful or nonpainful posttraumatic trigeminal neuropathy, psychophysical tests like quantitative sensory testing (QST) and qualitative sensory testing and the electrophysiological "nociceptive-specific" blink reflex were performed. The patients and 20 healthy participants completed a set of questionnaires assessing their psychosocial status and quality of life.RESULTS: A loss or gain of somatosensory function was seen in at least 1 QST parameter in >88.9% of the patients. Patients in whom extraoral QST was performed showed an overall loss of somatosensory function, whereas intraoral QST showed a general gain of somatosensory function. Qualitative sensory testing identified a side-to-side difference in the tactile and pinprick stimulation in >77% of the patients. An abnormal "nociceptive-specific" blink reflex response was seen in 42.1% to 71.4% of patients dependent on the trigeminal branch stimulated, though comparisons with healthy reference values showed ambiguous results. Compared with the healthy participants, patients showed higher scores for pain catastrophizing, symptoms of depression and anxiety, limited jaw function, more somatic symptoms, and significantly impaired oral health-related quality of life (all P<0.038).DISCUSSION: The results from the present study showed presence of varied somatosensory abnormalities when assessed using psychophysical and electrophysiological investigations and a significantly impaired psychosocial status.

- Objectives: Nonpharmacologic pain management strategies are needed because of the growing opioid epidemic. While studies have examined the efficacy of virtual reality (VR) for pain reduction, there is little research in adult inpatient settings, and no studies comparing the relative efficacy of standard animated computer-generated imagery (CGI) VR to Video Capture VR (360 degrees 3D/stereoscopic Video Capture VR). Here, we report on a randomized controlled trial of the relative efficacy of standard CGI VR versus Video Capture VR (matched for content) and also compared the overall efficacy of VR to a waitlist control group.Materials and Methods: Participants (N=103 hospitalized inpatients reporting pain) were randomized to 1 of 3 conditions: (1) waitlist control, (2) CGI VR, or (3) Video Capture VR. The VR and waitlist conditions were 10 minutes in length. Outcomes were assessed pretreatment, post-treatment, and after a brief follow-up.Results: Consistent with hypotheses, both VR conditions reduced pain significantly more relative to the waitlist control condition (d=1.60, P<0.001) and pain reductions were largely maintained at the brief follow-up assessment. Both VR conditions reduced pain by ∼50% and led to improvements in mood, anxiety, and relaxation. Contrary to prediction, the Video Capture VR condition was not significantly more effective at reducing pain relative to the CGI VR condition (d=0.25, P=0.216). However, as expected, patients randomized to the Video Capture VR rated their experience as more positive and realistic (d=0.78, P=0.002).Discussion: Video Capture VR was as effective as CGI VR for pain reduction and was rated as more realistic.

- Background:The use of strong opioids for treatment of noncancer chronic pain has increased. However, strong evidence for sustained pain relief and improved function is lacking. Controversy prevails, whether hormonal changes are induced by long-term treatment with opioids. The purpose of this study was to investigate the occurrence of endocrine dysfunction in chronic pain patients on long-term opioid treatment.Methods:A study group of 39 chronic pain patients treated with strong oral opioids for more than 1 year was compared with a control group of 20 chronic pain patients without opioid treatment. Basic levels of prolactin and function of the hypothalamic-pituitary-thyroid-, hypothalamic-pituitary-adrenal-axis, and hypothalamic-pituitary-growth-hormone - and hypothalamic-pituitary-gonadal-axis were measured. Quality-of-life and side effects were estimated with EORTC-QLQ-C30.Results:In the opioid-treated group, the patients had signs of pituitary dysfunction affecting all axes. Significant differences were shown in hypofunction of the hypothalamic-pituitary-gonadal -axis, hyperfunction of the hypothalamic-pituitary-adrenal -axis, and higher prolactin levels in the opioid-treated group, compared with the control group. The degree of pain was rated the same in both groups, but the opioid-treated group reported more side effects and lower quality of life.Conclusions:Long-term treatment of chronic pain with strong opioids causes side effects that can be attributed to hormonal abnormalities caused by opioid-induced inhibition of hypothalamic-pituitary function. Hormone substitution can be indicated to treat symptoms. Decreasing the opioid dose or stopping the opioid treatment can reverse endocrine dysfunction. This needs to be recognized by all practitioners treating chronic pain patients with opioids.

- Objective: To investigate whether a pretreatment multimodal (MM) assessment of patients with chronic muscular pain has an impact on treatment outcome. Methods: The present randomized-controlled study evaluated an MM assessment compared with routine multidisciplinary assessment given to a control group. The study population consisted of primary care patients with mixed chronic muscular pain. Variables assessed were: pain intensity, depression, life stress, quality of life (QOL), disability, working ability, and treatment satisfaction. Follow-up was performed at 15 months and 182 patients of 220 (83%) completed the study. Results: Univariate and multivariate logistic regression showed from baseline to 15 months a significant improvement in QOL as measured by Short-Form 36 in the MM group compared with the control group on the domains of physical function (odds ratio 2.40; 95% confidence interval 1.32-4.37), role physical (2.37; 1.10-5.09), and role emotional (2.05; 1.05-3.96). Working ability improved more significantly in the MM group (46% vs. 35%) and impairment was less (1% vs. 15%) compared with the control group (P = 0.016). Satisfaction with the assessment was, on average, higher (P < 0.001) in the MM group than in the control group. Discussion: Patients who underwent an MM assessment before treatment in comparison with patients receiving routine multidisciplinary assessment improved QOL, working ability, and were also significantly more satisfied. This result indicates that MM pretreatment assessment could be advantageous in the selection of patients for suitable rehabilitation treatment in a primary care setting, and also be used to prepare patients for future rehabilitation.

- Objectives: Nerve growth factor (NGF) is a protein important for growth and survival, but also for modulation of sensitivity of nociceptors and sympathetic neurons. The purpose of the present study was to investigate the effects of reduced NGF signaling in patients with hereditary sensory and autonomic neuropathies type V, congenital insensitivity to pain, caused by a mutation of the NGF beta gene, including a characterization of single nociceptive fibers using microneurography (MNG).Materials and Methods: One homozygote and 2 heterozygote patients with this mutation were examined with electromyography/neurography, thermal testing, quantitative sudomotor axon reflex test, and electrically induced axon reflex erythema in addition to MNG.Results: Low quantitative sudomotor axon reflex test measurements of 0.02 (left foot) and 0.03 (right foot) mL/cm(2) and elevated thermal thresholds for warmth and cold detection testing showed clear impairment of small nerve fibers, both sudomotor efferent and somatic afferent fibers, in the patient homozygote for the mutation. MNG from one of the heterozygote patients revealed changes in the small nociceptive fibers in skin, including abnormally low conduction velocity, spontaneous activity in A-delta fibers and C-nociceptors and abnormal or lacking response to heat.Discussion: The findings of grossly intact pain thresholds compared with anamnestic insensitivity of pain in deep somatic tissue such as bone suggest a gradient of impairment dependent on different NGF availability in various tissues. Even though these patients in some aspects report insensitivity to pain, they also report chronic spontaneous pain as their main symptom, strikingly highlighting differential mechanisms of insensitivity to evoked pain versus spontaneous pain.

- Background: The evaluation of tenderness associated with greater trochanteric pain (GTP) syndrome is amenable to bias and depends on the examiner's experience. In this study, we tested whether the use of an electronic pressure algometer enhanced the reliability of this evaluation.Patients and methods: Pressure-pain threshold (PPT) was measured with an electronic algometer in 18 patients who developed GTP after total hip arthroplasty and in matched controls. Both groups were evaluated with visual analog scale.Results: The PPT measurements showed large interindividual variability across patients. The correspondence of the PPT measurements in asymptomatic patients was good. We found good validity for the algometer used. The PPT ratio of 0.8 (affected vs. unaffected side) can be used as a cut-off ratio. The PPT measurements at the greater trochanter (local pain) were significantly lower than at the ilio-tibial band (radiated pain). There was no correlation between PPT measurements and visual analog scales. Despite the acceptable sensitivity and specificity of pressure algometer, because of low positive predictive value and large interindividual variability, pressure algometer has a limited value as a screening test.Conclusions: The examination of tenderness associated with GTP is facilitated by the used algometer. It is the intraindividual body-side PPT differences that yield the most sensitive measurement for the assessment of deep pain. A cut-off value of 0.8 can be used for diagnostic purposes. Interindividual differences might be considerable and could mask pathologic diagnostic findings.

- OBJECTIVES: The 1-month Graded Chronic Pain Scale (GCPS) commonly used in clinical studies has never been validated. This study compares the GCPS 1-month with the 6-months version for reliability and validity.METHODS: The Validation Project included 521 subjects with at least one temporomandibular disorder for cross-sectional data and 74 subjects for test-retest data. Internal reliability, stability, and construct validity were used for testing the 1-month version. Comparisons were made between the two versions for characteristic pain intensity (CPI), interference, and chronic pain grade (CPG).RESULTS: For GCPS 1-month, internal consistency for pain intensity and interference was high (Cronbach's alpha=0.87 and 0.94, respectively), and temporal stability was high for CPI (intraclass correlation coefficient (ICC)=0.91), interference (ICC=0.85), and CPG (weighted kappa=0.88). ICC or kappa between the two versions was 0.78 (CPI), 0.66 (interference), and 0.69 (CPG); high-impact pain, in contrast, was 0.50. Construct validity exhibited higher correlations with predictor variables for 1-month version attributes of CPI, interference, and CPG. Modified Bland-Altman plots indicated that both versions measure CPI well.DISCUSSION: Overall, reliability of the 1-month GCPS is equal to or better than the 6-months version for pain intensity, disability days, pain interference, CPG, and high-impact pain. However, consistency between versions is lower for measures of disability days and interference, and for the derived measures of CPG and high-impact pain; highly skewed distributions and increasing disagreement in reported status over the time periods affect the measures of function. Therefore, we recommend that GCPS-1 month only be used to calculate pain intensity and pain interference.

- Objectives: To compare naprapathic manual therapy with evidence-based care for back or neck pain regarding pain, disability, and perceived recovery. Naprapathy that is common in the Nordic countries and in some states in the United States is characterized by manual manipulations with a focus on soft and connective tissues, aiming to decrease pain and disability in the musculoskeletal system. Methods: Four hundred and nine patients with pain and disability in the back or neck lasting for at least 2 weeks, recruited at 2 large public companies in Sweden in 2005, were included in this randomized controlled trial. The 2 interventions were naprapathy, including spinal manipulation/mobilization, massage, and stretching (Index Group) and support and advice to stay active and how to cope with pain, according to the best scientific evidence available, provided by a physician (Control Group). Pain, disability, and perceived recovery were measured by questionnaires at baseline and after 3, 7, and 12 weeks. Results: At 7-week and 12-week follow-ups, statistically significant differences between the groups were found in all outcomes favoring the Index Group. At 12-week follow-up, a higher proportion in the naprapathy group had improved regarding pain [risk difference (RD) = 27%, 95% confidence interval (Cl): 17-37], disability (RD = 18%, 95% Cl: 7-28), and perceived recovery (RD = 44%, 95% Cl: 35-53). Separate analysis of neck pain and back pain patients showed similar results. Discussion: This trial suggests that combined manual therapy, like naprapathy, might be an alternative to consider for back and neck pain patients.

- OBJECTIVES: The aim of the study was to evaluate the therapeutic effect of electro-acupuncture (EA) and hydrotherapy, both in combination with patient education or with patient education alone, in the treatment of osteoarthritis in the hip. METHODS: Forty-five patients, aged 42-86 years, with radiographic changes consistent with osteoarthritis in the hip, pain related to motion, pain on load, and ache were chosen. They were randomly allocated to EA, hydrotherapy, both in combination with patient education, or patient education alone. Outcome measures were the disability rating index (DRI), global self-rating index (GSI), and visual analogue scale (VAS). Assessments were done before the intervention and immediately after the last treatment and 1, 3, and 6 months after the last treatment. RESULTS: Pain related to motion and pain on load was reduced up to 3 months after last the treatment in the hydrotherapy group and up to 6 months in the EA group. Ache during the day was significantly improved in both the EA and hydrotherapy group up to 3 months after the last treatment. Ache during the night was reduced in the hydrotherapy group up to 3 months after the last treatment and in the EA group up to 6 months after. Disability in functional activities was improved in EA and hydrotherapy groups up to 6 months after the last treatment. Quality of life was also improved in EA and hydrotherapy groups up to 3 months after the last treatment. There were no changes in the education group alone. DISCUSSION: In conclusion, EA and hydrotherapy, both in combination with patient education, induce long-lasting effects, shown by reduced pain and ache and by increased functional activity and quality of life, as demonstrated by differences in the pre- and post-treatment assessments.
