Objective

Clinicians and researchers often use the numeric pain rating scale (NPRS) and visual analog scale (VAS) to measure and track pain in individuals with myofascial pain syndrome (MPS) and fibromyalgia (FM). The VAS is often used as a reference standard in chronic pain research. To date, no studies have specifically measured the concurrent validity of the NPRS and VAS in these individuals. The purpose of this investigation was to determine the concurrent validity of the NPRS when compared to the reference standard VAS in patients with MPS and FM.

Methods

This investigation explored the concurrent validity of the NPRS and VAS in sixty participants with MPS (N = 30) and FM (N = 30). All participants underwent one day of testing using the American College of Rheumatology criteria for classifying FM. For each tender point (18-total), participants graded tenderness using the NPRS and VAS.

Results

An excellent relationship was found between the NPRS and VAS for the MPS group (rho≥0.81, 95% CI 0.79-0.85, p < 0.001) and the FM group (rho ≥0.96, 95% CI 0.92-0.97, p < 0.001).

Conclusion

The results of this study suggest that the NPRS has good concurrent validity with the referenced standard VAS among individuals with MPS and FM.  相似文献

Objective

To determine the effect of mobilization and routine physiotherapy on pain, disability, neck range of motion (ROM) and neck muscle endurance (NME) in patients having chronic mechanical neck pain (NP).

Methods

Sixty eight patients with chronic mechanical NP were randomly allocated into two groups by using a computer generated random sequence table with 34 patients in the multi-modal mobilization group and 34 patients in the routine physiotherapy group. Baseline values for pain, disability, NME, and neck ROM were recorded using visual analogue scale (VAS), neck disability index (NDI), neck flexor muscle endurance test and universal goniometer respectively, before the treatment. Each patient received 10 treatment sessions over a period of four weeks and at the end of four weeks all the outcome measures were recorded again.

Results

A paired t-test revealed significant pre to post treatment differences for all outcome measures in both groups (p ≤ 0.001 in all instances). An independent t-test revealed statistically significant differences for pain, disability, NME, and neck ROM in favor of the multi-modal mobilization group with a between group difference of 1.57 cm for VAS (p < 0.001), 11.74 points for NDI (p = 0.001), 18.45 s for NME (p < 0.001) and 6.06–8.24° for neck ROM (p < 0.05).

Conclusion

The results suggest that a combination of cervical mobilization with routine physiotherapy is more effective for reducing pain and disability and improving NME and neck ROM in patients with chronic mechanical NP compared to routine physiotherapy alone.  相似文献

Objective

To investigate the effects of an osteopathic manipulative treatment (OMT), which includes a diaphragm intervention compared to the same OMT with a sham diaphragm intervention in chronic nonspecific low back pain (NS-CLBP).

Design

Parallel group randomized controlled trial.

Setting

Private and institutional health centers.

Participants

Participants (N=66) (18-60y) with a diagnosis of NS-CLBP lasting at least 3 months.

Interventions

Participants were randomized to receive either an OMT protocol including specific diaphragm techniques (n=33) or the same OMT protocol with a sham diaphragm intervention (n=33), conducted in 5 sessions provided during 4 weeks.

Main Outcome Measures

The primary outcomes were pain (evaluated with the Short-Form McGill Pain Questionnaire [SF-MPQ] and the visual analog scale [VAS]) and disability (assessed with the Roland–Morris Questionnaire [RMQ] and the Oswestry Disability Index [ODI]). Secondary outcomes were fear-avoidance beliefs, level of anxiety and depression, and pain catastrophization. All outcome measures were evaluated at baseline, at week 4, and at week 12.

Results

A statistically significant reduction was observed in the experimental group compared to the sham group in all variables assessed at week 4 and at week 12 (SF-MPQ [mean difference ?6.2; 95% confidence interval, ?8.6 to ?3.8]; VAS [mean difference ?2.7; 95% confidence interval, ?3.6 to ?1.8]; RMQ [mean difference ?3.8; 95% confidence interval, ?5.4 to ?2.2]; ODI [mean difference ?10.6; 95% confidence interval, ?14.9 to 6.3]). Moreover, improvements in pain and disability were clinically relevant.

Conclusions

An OMT protocol that includes diaphragm techniques produces significant and clinically relevant improvements in pain and disability in patients with NS-CLBP compared to the same OMT protocol using sham diaphragm techniques.  相似文献

Objective

assess the effects of ischemic compression and kinesiotherapy on the rehabilitation of breast cancer survivors with chronic myofascial pain.

Methods

A randomized, controlled, blinded clinical trial was performed with 20 breast cancer survivors with myofascial trigger point in the upper trapezius muscle. Patients were randomly allocated to ischemic compression + kinesiotherapy (G1, n = 10) and kinesiotherapy (G2, n = 10). Both groups were submitted to 10 sessions of treatment. The variables evaluated were: Numeric Rating Scale, Pain Related Self-Statement Scale, pressure pain threshold, Functional Assessment of Cancer Therapy-Breast and Infrared thermography.

Results

A significant reduction (p < 0.05) was observed in pain intensity after 10 sessions in Groups 1 and 2, a significant increase (p < 0.05) in pressure pain threshold in both the operated and non-operated side after 10 sessions for Group 1.

Conclusion

Ischemic compression associated with kinesiotherapy increases the pressure pain threshold on the myofascial trigger point in the upper trapezius muscle and reduces the intensity of pain in breast cancer survivors with myofascial pain.  相似文献

Background

Treatment of movement faults in the neck is known as an important factor in treatment of chronic neck pain. Along with the identification of site and direction of the faults, direction-movement control intervention retrains the control of the movement faults.

Purpose

This study was designed to investigate long-term effects of a direction-movement control training on pain, disability, head repositioning accuracy, function, cervical flexor endurance, and range of motion in female patients with chronic nonspecific neck pain.

Material and methods

Thirty women (36.5 ± 5.7 years) with chronic nonspecific neck pain were randomly allocated into two groups, i.e., an experimental group (n = 15) and a control group (n = 15). The experimental group performed the direction-movement control training for 30 min/day, three days per week for six months.All subjects were evaluated using the visual analog scale (VAS), range of motion (TOM), progressive iso-inertial lifting evaluation (PILE), neck disability Index (NDI), helmet attached with laser pointer using for head repositioning accuracy (HRA), and Trott's test (deep neck flexor endurance), in pre- and six-months post-treatment intervention.

Results

Significant differences were observed for the pain, neck disability Index, function endurance, head repositioning accuracy, range of motion, and cervical flexor endurance in the experimental group compared to that of control group.

Conclusion

Direction-movement control training is likely to be an effective training program to enhance body functionality through improvement of pain, function, endurance, head repositioning accuracy, range of motion, and cervical flexor endurance. Due to the high reported effect size for direction-movement control exercises, the application of the training is suggested as a supplementary method to improve chronic nonspecific neck pain in females.  相似文献

Question

What are the effects of patellar taping on pain, functional disability and patellar alignments in Patellofemoral Pain Syndrome (PFPS)?

Design

Double-blind randomized clinical trial.

Participants

Thirty PFPS Patients were randomly divided into two groups, intervention and control.Intervention: Patients in control group received only the routine physiotherapy. In addition to routine physiotherapy, patellar taping was used in the intervention group. Each patient was treated for 12 sessions over a period of 4 weeks.

Outcome measures

The KOOS and VAS questionnaires were used to assess the quality of life (QOL) and pain intensity, respectively. Three components of patellar alignment including Patellofemoral Congruence Angle (PFCA), Lateral Patellofemoral Angle (LPFA) and Lateral Patellar Displacement (LPD) were evaluated using the skyline radiography method.

Results

The results indicated that there was no significant difference between the control and intervention groups for LPD (P = 0.586), PFCA (P = 0.704) and LPFA (P = 0.176) variables. No significant difference was found between the two groups in all items of the KOOS questionnaire. The knee pain intensity was significantly reduced in both the intervention (P < 0.001) and control (P = 0.001) groups at the end of the 4th week.

Conclusion

The results of the present study indicated that patellar taping compared to routine physiotherapy treatments had no beneficial effects on pain reduction, QOL improvement and correction of patellar alignment in PSPS patients.

Introduction

Chronic non-specific low back pain (LBP) may lead to functional impairment and physical disability. The aim of this study was to compare the effects of selective Pilates (SP) and extension-based (EB) exercises on pain, lumbar spine curvature, lumbar forward flexion range of motion (ROM), and physical disability in such individuals.

Materials and methods

In this randomized clinical trial, Forty-seven patients with chronic non-specific LBP (Mean of age: 39.7 years) were randomly allocated into either SP (N = 16), EB (N = 15), or control (N = 16) groups. The measurements included pain intensity, physical disability, lumbar forward bending ROM, and lumbar spine curvature at the baseline, after receiving the 6-week interventions, and also following one month of cessation of the exercises The analysis of co-variance (ANCOVA) and Post-hoc Bonferroni tests were administered to compare the three groups after the interventions and one month later (P < 0.05).

Results

More significant improvement was observed in SP group compared to the subjects receiving EB exercises in terms of pain, ROM, and physical disability (P < 0.001), however, there was no significant difference between the two experimental groups for lumbar curvature (P > 0.05). Furthermore; in follow-up, the patients in SP group significantly achieved a higher level of pain intensity improvement and lumbar flexion ROM than the EB exercises (P < 0.001).

Conclusions

It is estimated that core muscles activation and improving lumbopelvic rhythm in SP training may play a role in decreasing pain and physical disability in chronic LBP patients. Further high-quality studies are required to investigate the details of this mechanism.  相似文献

Background

Maitland Mobilization or Mulligan Mobilization with Movement (MWM) approaches have been widely used clinically for pain relief and improving mobility in Osteoarthritis knee. However the experimental evidence supporting the usage of these mobilization techniques as sole interventions in management of Osteoarthritis knee is insufficient.

Objective

To determine from Maitland Mobilization and Mulligan MWM, which mobilization technique will be more effective in reducing pain and improving mobility and function in OA knee immediately after the intervention.

Study design

Randomized Crossover trial.

Materials and methods

30 subjects with osteoarthritis knee were recruited and 15 each were randomly allocated to two intervention sequences-one sequence was where Maitland was given first followed by Mulligan and the other was where Mulligan was given first followed by Maitland with a washout period of 48 h in between the two interventions. Numeric Pain Rating Scale (NPRS), Timed Up and Go (TUG) test and Pain free Squat Angle were the outcome measures measured before and immediately after both interventions.

Results

Using Repeated Measures ANOVA for analysis of outcomes between and within interventions, no significant differences were seen between Maitland Mobilization and Mulligan MWM, for NPRS, TUG and Pain free Squat Angle (p = 0.18, p = 0.27,p = 0.17) respectively whereas within the interventions both Maitland and Mulligan all outcome measures showed significant changes (p < 0.001).

Conclusion

Thus it can be seen that Maitland mobilization and Mulligan MWM, both are equally effective in osteoarthritis knee in reducing pain and improving functional mobility and pain free squat angle immediately post treatment.  相似文献

Background

Chronic fatigue syndrome (CFS) is a general term used to describe a number of medical conditions that lead to persistent levels of fatigue and distress.

Objectives

Osteopathic manipulative treatment (OMT) combined with shoulder exercises to resolve musculoskeletal sports injury may have also led to a reduction in pain and improved strength with the patient reporting a change in CFS levels.

Clinical features

19-year-old male student, (statue 194cm and mass 80kg) who had played county level cricket and hockey. Presented with a two-year history of left shoulder pain (VAS 8/10) and a diagnosis of chronic fatigue syndrome.

Intervention and outcomes

OMT was performed over four clinical visits throughout a four a month period. Management goal was pain reduction, neural regulation, and facilitation of breathing mechanics to improve lymphatic drainage and restoration of shoulder strength and control.

Conclusion

Clinically a reduction in pain (VAS 8/10–0/10) over four treatments appeared to correlate with improved shoulder strength. It was also reported that due to pain reduction, CFS might have improved.  相似文献

Background

Neck pain is a common musculoskeletal complaint in computer users due to prolonged static or awkward work postures. It has been shown that pathogenesis of neck pain is associated with scapular movement impairment syndromes. However, there is a dearth of literature in treatment based on these syndromes.

Aim

To identify the effects of movement impairment-based treatment in the management of mechanical neck pain, in computer users.

Methods

In the present study, twenty-seven subjects were recruited. Based on the identified scapular impairment syndrome, they were trained with scapular movement impairment-based exercises for four weeks. Pain, disability and cervical range of motion were measured with numeric pain rating scale, neck disability index and inclinometer, respectively, at baseline and at four weeks.

Results

Twenty-one subjects completed the study. After four weeks, a significant difference of 4.81 points for numeric pain rating scale and 24.47% for neck disability index at 95% CI were found. The cervical range of motion showed a significant change (p < 0.05) of 10.09° for flexion, 24.47° for extension, 7.42° for right lateral flexion, 6.23° for left lateral flexion, 15.52° for right rotation and 14.95° for left rotation at 95% CI.

Conclusions

Exercises based on scapular impairment syndromes were given for four weeks. It was found to be effective in relieving pain and reducing dysfunction in computer users with mechanical neck pain  相似文献

Aim

This study aimed to compare the prevalence of pelvic musculoskeletal dysfunctions in women with and without Chronic Pelvic Pain (CPP).

Materials &Methods

A total of 84 women with and without CPP (42 in each group), participated in this cross-sectional analytical study. After collecting demographic information, clinical examinations were carried out to compare pelvic musculoskeletal dysfunctions between two groups. Kolmogorov-Smirnov (K-S) goodness-of-fit, Independent t, X2 and Pearson correlation tests were used for data analysis. Values of p < 0.05 were considered statistically significant.

Findings

Significant differences were found in the asymmetric iliac crest and pubic symphysis height (45.2% vs 9.5%), positive sacroiliac provocation and positive Carnett's tests (50% vs 4.8%), (p < 0.05). CPP Patients exhibited more tenderness at Levator ani, Piriformis, and Obturator Internus muscles, also higher degrees of pelvic inclination (p < 0.05).

Conclusion

Higher frequency of pelvic musculoskeletal dysfunctions in women with CPP suggests the value of routine musculoskeletal examinations for earlier diagnosis of musculoskeletal originated CPP and effective management of these patients.  相似文献

Objectives

The role of a myofascial release (MFR) on flexion contractures after total knee arthroplasty (TKA) has not yet been elucidated. Therefore, the purpose of this study was to determine its immediate effect on such patients.

Methods

In this A-B single subject experimental study, 33 TKA's patients with knee flexion contracture had their gluteal, posterior fascia lata, posterior crural and plantar fasciae released. Patients' knee range of motion (KROM), pain and muscle electric activity were assessed pre- and post-intervention.

Results

An increase in electric activity of the biceps femoris muscle was identified after treatment (pre RMS = 0.087 ± 0.066 V; post RMS = 0.097 ± 0.085 V; p = 0.037). Mean gain of KROM was 5.72 ± 6.27, correspondent to an 11.9% improvement (p = 0.01). Eight subjects had their pain decreased on 56.9% (p = 0.04).

Conclusions

MFR increased muscle activity, reduced pain and improved the KROM of TKA patients. Thus, MFR is a useful resource of rehabilitation after TKA.  相似文献

Context

The achievement of a personalized pain goal (PPG) is advocated as an individualized pain relief indicator.

Objectives

Pain relief indicators, including PPG, pain intensity (PI), and interference with daily activities (interference), were compared herein.

Methods

This was a single-center cross-sectional study. Adult patients with cancer on opioid medications who visited the outpatient clinic at the National Cancer Center Hospital East between March and September 2015 were consecutively enrolled. Patients conducted a self-report questionnaire, including reports of average PI, interference, PPG, and the need for further analgesic treatment. We compared the proportion of patients achieving PPG (PI ≤ PPG) and other pain relief indicators including PI ≤3 or interference ≤3 and the percentage of patients who did not need further analgesic treatment among those who fulfilled each pain relief indicator.

Results

A total of 347 patients (median age 64; 38% females) were analyzed. Median (interquartile range [IQR]) of PPG, PI, and interference was 2 (IQR 1–3), 2 (IQR 1–4), and 2 (IQR 0–5), respectively. The proportion of patients achieving PPG was 45.3% and significantly lower than those with PI ≤3 (69.0%; P < 0.001) and interference ≤3 (70.2%; P < 0.001). Eighty percent of patients achieving PPG did not need further analgesic treatment, whereas 70.8% of patients with PI ≤3 (P < 0.001) and 73.3% with interference ≤3 did need further analgesic treatment (P < 0.001).

Conclusion

The achievement of PPG was a stricter pain relief indicator than PI and interference and may reflect a real need for pain control.  相似文献

Objective

To determine the amplitude of the electromyographic activity of trunk muscles during Pilates exercises in women with and without chronic low back pain (LBP).

Design

Case-control study.

Setting

University physical therapy clinic.

Participants

Women (N=60) divided into an LBP group and a control group.

Interventions

Not applicable.

Main Outcome Measures

Amplitude of the electromyographic activity (root mean square values) of the gluteus maximus and external oblique muscles collected during 3 Pilates exercises: Shoulder Bridge performed on the mat, and Hip Roll and Breathing performed in equipment. Pain intensity was assessed in the LBP group.

Results

The amplitude of the electromyographic activity was similar between groups (P≥.05). For both groups, the amplitude of the gluteus maximus was higher in the Shoulder Bridge exercise compared with the Hip Roll with 2 springs (control group: mean difference [MD]=.18; 95% confidence interval [CI], .05–.41; LBP group: MD=.29; 95% CI, .16–.31) and the Breathing exercise (control group: MD=?.40; 95% CI, ?.55 to ?.26; LBP group: MD=?.36; 95% CI, ?.52 to ?.20). The amplitude of the external oblique muscle was higher in the Shoulder Bridge compared with the Hip Roll with 2 springs (control group: MD=.13; 95% CI, .05–.21; LBP group: MD=.18; 95% CI, .03–.33). Pain intensity increased after exercises, but this increase was lower for the mat exercises.

Conclusions

Similar muscle activation between groups was found. The findings suggest that mat exercises caused less pain and a greater difference in the amplitude of muscle activation compared with the equipment-based exercises.  相似文献

Objective

To evaluate the current evidence of the effectiveness of dry needling of myofascial trigger points (MTrPs) associated with low back pain (LBP).

Data Sources

PubMed, Ovid, EBSCO, ScienceDirect, Web of Science, Cochrane Library, CINAHL, and China National Knowledge Infrastructure databases were searched until January 2017.

Study Selection

Randomized controlled trials (RCTs) that used dry needling as the main treatment and included participants diagnosed with LBP with the presence of MTrPs were included.

Data Extraction

Two reviewers independently screened articles, scored methodologic quality, and extracted data. The primary outcomes were pain intensity and functional disability at postintervention and follow-up.

Data Synthesis

A total of 11 RCTs involving 802 patients were included in the meta-analysis. Results suggested that compared with other treatments, dry needling of MTrPs was more effective in alleviating the intensity of LBP (standardized mean difference [SMD], ?1.06; 95% confidence interval [CI], ?1.77 to ?0.36; P=.003) and functional disability (SMD, ?0.76; 95% CI, ?1.46 to ?0.06; P=.03); however, the significant effects of dry needling plus other treatments on pain intensity could be superior to dry needling alone for LBP at postintervention (SMD, 0.83; 95% CI, 0.55–1.11; P<.00001).

Conclusions

Moderate evidence showed that dry needling of MTrPs, especially if associated with other therapies, could be recommended to relieve the intensity of LBP at postintervention; however, the clinical superiority of dry needling in improving functional disability and its follow-up effects still remains unclear.  相似文献

Background

A myofascial trigger point (MTrP) has been defined as a hyperirritable, palpable nodule in a skeletal muscle. The signs and symptoms of a MTrP include muscle pain, weakness, and dysfunction. MTrPs are common problems associated with soft tissue pathology. Having an intervention to decrease MTrP pain can be clinically valuable.

Purpose

To determine if a series of six instrument-assisted soft tissue mobilization (IASTM) treatments rendered over three weeks would influence the pressure pain threshold (PPT) of a myofascial trigger point (MTrP).

Methods

Randomized, control trial of healthy individuals (n = 29) with MTrPs in the upper trapezius muscle. The intervention was six IASTM treatments rendered over three weeks. Each treatment included 1 min of sweeping with the GT-1/HG-2 (handle bar), 1 min of swivel with the knob of the GT-1/HG-2 directly over the MTrP, 2 min of fanning with the GT-4/HG-8 (convex single bevel), and concluded with 1 min of sweeping with GT-1/HG-2.The outcome measure used a dolorimeter to compare PPT before and after three weeks in both the treatment and control groups.

Results

Paired t-test for PPT pre-test and post-test of the control and treatment groups were p = 0.42159 and p = 0.00003, respectively. A one-way ANOVA of the control and IASTM groups revealed a statistically significant difference (p < 0.0001). The power calculation was greater than 0.99.

Conclusions

A 5-min intervention using three IASTM techniques can effectively increase the PPT of a MTrP in six treatments over a three-week period of time.  相似文献

Background

Pain management in the emergency department (ED) remains suboptimal. Nursing staff protocols could improve this, but studies show divergent results.

Objective

Our aim was to evaluate a nurse-initiated pain-management protocol in adult patients with traumatic injuries in the short and in the long term, utilizing fentanyl for severe pain.

Methods

In this pre–post implementation study, ED patients were included during three periods. The protocol allowed nurses to administer acetaminophen, non-steroidal anti-inflammatory drugs, or fentanyl autonomously, based on Numeric Rating Scale pain scores. Primary outcome was frequency of analgesic administration at 6 and 18 months after implementation. Secondary outcomes were pain awareness, occurrence of adverse events, and pain treatment after discharge.

Results

Five hundred and twelve patients before implementation were compared with 507 and 468 patients at 6 and 18 months after implementation, respectively. Analgesic administration increased significantly at 18 months (from 29% to 36%; p = 0.016), not at 6 months (33%; p = 0.19) after implementation. Pain awareness increased from 30% to 51% (p = 0.00) at 6 months and to 56% (p = 0.00) at 18 months, due to a significant increase in pain assessment: 3% to 30% (p = 0.00) and 32% (p = 0.00), respectively. Post-discharge pain treatment increased significantly at 18 months compared to baseline (from 25% to 33%; p = 0.016) and to 6 months (from 24% to 33%; p = 0.004). No adverse events were recorded.

Conclusions

Implementation of a nurse-initiated pain-management protocol only increases analgesic administration in adult patients with traumatic injuries in the long term. Auditing might have promoted adherence. Pain awareness increases significantly in the short and the long term.  相似文献

Background

The deterioration in the somatosensory and motor systems observed with increasing age can cause balance problems. Studies have shown that the use of infrapatellar bandages can enhance proprioception and improve postural balance.

Aims

To evaluate the effect of an infrapatellar bandage on static balance and mobility in elderly female fallers and non-fallers.

Methods

Forty older women (20 fallers and 20 non-fallers) were evaluated. Mobility (Timed Up and Go test) and balance (force platform) were measured in the presence and absence of additional sensory information (elastic infrapatellar bandage).

Results

Mobility differed in fallers (p = 0.0001), but not in non-fallers (p = 0.27), when the patellar bandage was applied. Additional sensory information did not improve static balance in either group (p > 0.05), but a trend towards improvement was observed in fallers.

Conclusion

Additional sensory input from an infrapatellar bandage improves mobility but not bipedal stance in elderly fallers.  相似文献

Context

Pain is a common and distressing symptom. Pain management is a core competency for palliative care (PC) teams.

Objective

Identify characteristics associated with pain and pain improvement among inpatients referred to PC.

Methods

Thirty-eight inpatient PC teams in the Palliative Care Quality Network entered data about patients seen between December 12, 2012 and March 15, 2016. We examined patient and care characteristics associated with pain and pain improvement.

Results

Of patients who could self-report symptoms, 30.7% (4959 of 16,158) reported moderate-to-severe pain at first assessment. Over 40% of these patients had not been referred to PC for pain. Younger patients (P < 0.0001), women (P < 0.0001), patients with cancer (P < 0.0001), and patients in medical/surgical units (P < 0.0001) were more likely to report pain. Patients with pain had higher rates of anxiety (P < 0.0001), nausea (P < 0.0001), and dyspnea (P < 0.0001). Sixty-eight percent of patients with moderate-to-severe pain improved by the PC team's second assessment within 72 hours; 74.7% improved by final assessment. There was a significant variation in the rate of pain improvement between PC teams (P < 0.0001). Improvement in pain was associated with improvement in anxiety (OR = 2.9, P < 0.0001) and dyspnea (OR = 1.4, P = 0.03). Patients who reported an improvement in pain had shorter hospital length-of-stay by two days (P = 0.003).

Conclusion

Pain is common among inpatients referred to PC. Three-quarters of patients with pain improve and improvement in pain is associated with other symptom improvement. Standardized, multisite data collection can identify PC patients likely to have marked and refractory pain, create benchmarks for the field, and identify best practices to inform quality improvement.  相似文献
