Literature review of nonpharmacologic methods for the treatment of chronic pain

Associations between psychological symptoms and treatment outcomes of a massage therapy intervention: Secondary analyses of a randomized controlled trial

Massage therapy (MT) may be more effective for certain subgroups of advanced cancer patients, but this is not well-studied. Psychological symptoms are one potential moderator of MT outcomes, as they occur frequently in MT patients. Therefore, we conducted a secondary analysis of data from a multi-site study which compared MT to simple touch in 380 adults with advanced cancer. We examined whether the presence of depression or baseline psychological symptom frequency moderated outcomes of change in pain, interference of pain, quality of life, 60-second heart and respiratory rates, and physical distress. We found significant main effects of depression and baseline psychological symptom frequency on changes in pain, 60-second heart and respiratory rates, quality of life, and physical distress for both MT and simple touch, but did not find differential responses between groups in moderator analyses. Results imply that psychological interventions could be targeted to patients with cancer who are receiving any type of touch therapy to improve outcomes.

Low Back Pain: Current Surgical Approaches

Low back pain (LBP) is a worldwide phenomenon. The UK studies place LBP as the largest single cause of absence from work; up to 80% of the population will experience LBP at least once in their lifetime. Most individuals do not seek medical care and are not disabled by their pain once it is managed by nonoperative measures. However, around 10% of patients go on to develop chronic pain. This review outlines the basics of the traditional approach to spinal surgery for chronic LBP secondary to osteoarthritis of the lumbar spine as well as explains the novel concepts and terminology of back pain surgery. Traditionally, the stepwise approach to surgery starts with local anaesthetic and steroid injection followed by spinal fusion. Fusion aims to alleviate pain by preventing movement between affected spinal segments; this commonly involves open surgery, which requires large soft tissue dissection and there is a possibility of blood loss and prolonged recovery time. Established minimally invasive spine surgery techniques (MISS) aim to reduce all of these complications and they include laparoscopic anterior lumbar interbody fusion and MISS posterior instrumentation with pedicle screws and rods. Newer MISS techniques include extreme lateral interbody fusion and axial interbody fusion. The main problem of fusion is the disruption of the biomechanics of the rest of the spine; leading to adjacent level disease. Theoretically, this can be prevented by performing motion-preserving surgeries such as total disc replacement, facet arthroplasty, and non fusion stabilisation. We outline the basic concepts of the procedures mentioned above as well as explore some of the novel surgical therapies available for chronic LBP.

Massage therapy versus simple touch to improve pain and mood in patients with advanced cancer: a randomized trial

BACKGROUND

Small studies of variable quality suggest that massage therapy may relieve pain and other symptoms.

OBJECTIVE

To evaluate the efficacy of massage for decreasing pain and symptom distress and improving quality of life among persons with advanced cancer.

DESIGN

Multisite, randomized clinical trial.

SETTING

Population-based Palliative Care Research Network.

PATIENTS

380 adults with advanced cancer who were experiencing moderate-to-severe pain; 90% were enrolled in hospice.

INTERVENTION

Six 30-minute massage or simple-touch sessions over 2 weeks.

MEASUREMENTS

Primary outcomes were immediate (Memorial Pain Assessment Card, 0- to 10-point scale) and sustained (Brief Pain Inventory [BPI], 0- to 10-point scale) change in pain. Secondary outcomes were immediate change in mood (Memorial Pain Assessment Card) and 60-second heart and respiratory rates and sustained change in quality of life (McGill Quality of Life Questionnaire, 0- to 10-point scale), symptom distress (Memorial Symptom Assessment Scale, 0- to 4-point scale), and analgesic medication use (parenteral morphine equivalents [mg/d]). Immediate outcomes were obtained just before and after each treatment session. Sustained outcomes were obtained at baseline and weekly for 3 weeks.

RESULTS

298 persons were included in the immediate outcome analysis and 348 in the sustained outcome analysis. A total of 82 persons did not receive any allocated study treatments (37 massage patients, 45 control participants). Both groups demonstrated immediate improvement in pain (massage, -1.87 points [95% CI, -2.07 to -1.67 points]; control, -0.97 point [CI, -1.18 to -0.76 points]) and mood (massage, 1.58 points [CI, 1.40 to 1.76 points]; control, 0.97 point [CI, 0.78 to 1.16 points]). Massage was superior for both immediate pain and mood (mean difference, 0.90 and 0.61 points, respectively; P < 0.001). No between-group mean differences occurred over time in sustained pain (BPI mean pain, 0.07 point [CI, -0.23 to 0.37 points]; BPI worst pain, -0.14 point [CI, -0.59 to 0.31 points]), quality of life (McGill Quality of Life Questionnaire overall, 0.08 point [CI, -0.37 to 0.53 points]), symptom distress (Memorial Symptom Assessment Scale global distress index, -0.002 point [CI, -0.12 to 0.12 points]), or analgesic medication use (parenteral morphine equivalents, -0.10 mg/d [CI, -0.25 to 0.05 mg/d]).

LIMITATIONS

The immediate outcome measures were obtained by unblinded study therapists, possibly leading to reporting bias and the overestimation of a beneficial effect. The generalizability to all patients with advanced cancer is uncertain. The differential beneficial effect of massage therapy over simple touch is not conclusive without a usual care control group.

CONCLUSION

Massage may have immediately beneficial effects on pain and mood among patients with advanced cancer. Given the lack of sustained effects and the observed improvements in both study groups, the potential benefits of attention and simple touch should also be considered in this patient population.

In chronic low back pain, low level laser therapy combined with exercise is more beneficial than exercise alone in the long term: a randomised trial

QUESTION

Is low level laser therapy an effective adjuvant intervention for chronic low back pain?

DESIGN

Randomised trial with concealed allocation, blinded assessors and intention-to-treat analysis.

PARTICIPANTS

Sixty-one patients who had low back pain for at least 12 weeks.

INTERVENTION

One group received laser therapy alone, one received laser therapy and exercise, and the third group received placebo laser therapy and exercise. Laser therapy was performed twice a week for 6 weeks.

OUTCOME MEASURES

Outcomes were pain severity measured using a 10-cm visual analogue scale, lumbar range of motion measured by the Schober Test and maximum active flexion, extension and lateral flexion, and disability measured with the Oswestry Disability Index on admission to the study, after 6 weeks of intervention, and after another 6 weeks of no intervention.

RESULTS

There was no greater effect of laser therapy compared with exercise for any outcome, at either 6 or 12 weeks. There was also no greater effect of laser therapy plus exercise compared with exercise for any outcome at 6 weeks. However, in the laser therapy plus exercise group pain had reduced by 1.8 cm (95% CI 0.1 to 3.3, p = 0.03), lumbar range of movement increased by 0.9 cm (95% CI 0.2 to 1.8, p < 0.01) on the Schober Test and by 15 deg (95% CI 5 to 25, p < 0.01) of active flexion, and disability reduced by 9.4 points (95% CI 2.7 to 16.0, p = 0.03) more than in the exercise group at 12 weeks.

CONCLUSION

In chronic low back pain low level laser therapy combined with exercise is more beneficial than exercise alone in the long term.

Complementary therapies in action--education and outcomes

A study investigated the use of aromatherapy hand and foot massage on 11 patients in a rural rehabilitation setting. An education programme for nurses, carers and family members was developed and implemented. Clinical outcomes--pain, anxiety, joint flexibility and skin condition were evaluated using Likert scales completed before, and after, treatment at three time points and open questions to ascertain patients' feelings about the treatments. Each patient had three treatments, making a total of 33 massages. A significant reduction in pain and anxiety was apparent after all three treatments (p=0.05). Changes in skin condition (softer and more resilient) were highly significant (p=0.01). However, there was no significant change in joint flexibility (p<0.05). The main themes emerging from patients'comments were that aromatherapy massage facilitated communication, allowed emotional release and aided relaxation. Nine people undertook the education programme. They indicated that it covered appropriate information and they felt confident to deliver the aromatherapy massages, but the non-nursing participants would have liked more practice before they entered the clinical setting.

Effect of cutaneous stimulation on pain reduction in emergency department patients

CONTEXT

The problem of unrelieved pain in Emergency Department (ED) patients as well as contraindications to analgesics and narcotics due to masking of symptoms during the diagnostic period, presents itself as a unique opportunity for ED nurses to utilize non-pharmacological and non-invasive interventions such as cutaneous stimulation (CS) to relieve pain.

OBJECTIVE

To evaluate the effectiveness of a specific protocol of CS, developed by the researchers, in reducing pain levels in ED patients. Another objective was to determine the effect of CS on blood pressure and heart rate. Potential factors that could influence the dependent variables such as age, gender, educational level, location of pain, and site of CS were tested.

DESIGN

A one group pre-test post-test experimental design measured variables before and after intervention in all subjects.

SAMPLE

After being screened for inclusion, 50 patients (38 adults, 12 children) were admitted to the study and were treated with CS to relieve pain.

RESULTS

Following CS, subjects reported significantly reduced pain, and demonstrated reduced heart rate, and blood pressure readings. The location of pain significantly influenced heart rate and diastolic blood pressure but not pain level. The most effective site of CS was contralateral to the pain. Age, gender and educational level had no significant affect.

CONCLUSIONS

The results of this study provide empirical evidence that CS effectively reduces pain, heart rate, and blood pressure in ED patients. The intervention of CS has solid utilization potential and could be easily incorporated into standard ED procedure. Further research is needed to identify threats to internal validity especially that of the caring presence of the nurse.

The effects of shiatsu on lower back pain

Shiatsu, a specific type of massage, was used as an intervention in this study of 66 individuals complaining of lower back pain. Each individual was measured on state/trait anxiety and pain level before and after four shiatsu treatments. Each subject was then called 2 days following each treatment and asked to quantify the level of pain. Both pain and anxiety decreased significantly over time. Extraneous variables such as gender, age, gender of therapist, length of history with lower back pain, and medications taken for lower back pain did not alter the significant results. These subjects would recommend shiatsu massage for others suffering from lower back pain and indicated the treatments decreased the major inconveniences they experienced with their lower back pain.

Effect of therapeutic touch on the well-being of persons with terminal cancer

The purpose of this study was to examine the effect of three Therapeutic Touch treatments on the well-being of 20 persons with terminal cancer in palliative care. Participants in the experimental group (n = 10) received three noncontact Therapeutic Touch treatments, the duration of which varied between 15 to 20 minutes. Participants in the control group (n = 10) participated in three rest periods. Well-being was measured at preintervention time and immediately postintervention time using the Well-Being Scale, a visual analogue scale measuring pain, nausea, depression, anxiety, shortness of breath, activity, appetite, relaxation, and inner peace. The results of the study support the hypothesis that three noncontact Therapeutic Touch treatments increase sensation of well-being in persons with terminal cancer.

Reviews of units of care: combining practice, research and quality assurance

That nurses should base their practice on the best available knowledge is generally accepted by the profession. However, the operationalisation of this ideal if difficult for hard pressed clinicians. We believe that responsibility for assimilating current knowledge in a practical format belongs to all nurses working in an organisation. This paper describes a project where clinicians, administrators and academics have collaborated to rewrite standards of practice in a format that includes up to date evidence and practical measures for appraising outcomes. This work is a practical example of quality assurance activities serving to create opportunities for collaboration between nurses who have chosen to practice, teach, manage and/or research nursing.

Validation of cutaneous stimulation interventions for pain management

The purpose of this study was to identify and validate specific activities considered important in the implementation of selected cutaneous stimulation pain management interventions including heat and cold application, massage and Transcutaneous Electrical Nerve Stimulation (TENS). A two-round Delphi survey was completed by nurses selected for their expertise in pain management. Data were analyzed using a modification of Fehring's diagnostic content validity method. Consistently high scores were obtained by the raters for each intervention and activity, with most activities perceived as critical to the intervention. From this process, a list of activities for each cutaneous stimulation intervention evolved that are applicable to education, clinical practice and clinical nursing research.
