The immediate effects of modified Yoga positions on musculoskeletal pain relief

Factors influencing nurses' pain assessment and management of road traffic casualties: a qualitative study at a military hospital in Ghana

BACKGROUND

Evidence shows that patients who visit the surgical and trauma emergency units may be discharged with untreated or increased pain levels. This study explored nurses' pain assessment and management approaches at a trauma-surgical emergency unit in Ghana.

METHODS

Seventeen nurses who work in the trauma department participated in this qualitative exploratory descriptive study. In-depth individual interviews were conducted, and the thematic analysis was utilized to identify emerging themes and subthemes.

RESULTS

Three main themes were identified: patient pain indicators, pain management, and institutional factors influencing pain management. The study revealed that nurses rely on verbal expressions, non-verbal cues, physiological changes, and the severity of pain communicated. The findings highlighted staff shortage, inadequate resources, and lack of standardized guidelines as factors affecting pain and management.

CONCLUSIONS

Although the study offers critical new perspectives on nurses' experiences regarding pain related issues at the trauma-surgical emergency units, its small sample size limited its generalizability.

Blinding and sham control methods in trials of physical, psychological, and self-management interventions for pain (article II): a meta-analysis relating methods to trial results

ABSTRACT

Sham interventions in randomized clinical trials (RCTs) of physical, psychological, and self-management (PPS) therapies for pain are highly variable in design and believed to contribute to poor internal validity. However, it has not been formally tested whether the extent to which sham controls resemble the treatment under investigation consistently affects trial outcomes, such as effect sizes, differential attrition, participant expectancy, and blinding effectiveness. Placebo- or sham-controlled RCTs of PPS interventions of clinical pain populations were searched in 12 databases. The similarity of control interventions to the experimental treatment was rated across 25 features. Meta-regression analyses assessed putative links between employed control interventions, observed effect sizes in pain-related outcomes, attrition, and blinding success. The sample included 198 unique control interventions, dominated by manual therapy and chronic musculoskeletal pain research. Meta-analyses indicated small-to-moderate benefits of active treatments over control interventions, across subgroups of manual therapies, exercise, and rehabilitation, and psychological intervention trials. Multiple meta-regression modelling demonstrated that similarity between sham control and tested interventions predicted variability in pain-related outcomes, attrition, and blinding effectiveness. Influential variables were differences relating to the extent of intervention exposure, participant experience, and treatment environments. The results support the supposed link between blinding methods and effect sizes, based on a large and systematically sourced overview of methods. However, challenges to effective blinding are complex and often difficult to discern from trial reports. Nonetheless, these insights have the potential to change trial design, conduct, and reporting and will inform guideline development.

Designing, validation, and feasibility of a yoga module for patients with ankylosing spondylitis

BACKGROUND

Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes significant disability and reduced quality of life. Scientific studies on yoga have revealed its various health benefits in chronic conditions, including autoimmune diseases. However, whether yoga is feasible for AS patients or not is not studied. Further, no validated yoga module is available for AS patients.

OBJECTIVE(S)

This study intended to develop a yoga module for AS patients and investigated its feasibility of use.

MATERIALS AND METHODS

The study was completed in three stages. In Stage I, six yoga experts prepared a list of 64 yoga practices based on the classical and contemporary yogic literature review. Of these practices, 41 were included in the designed yoga module. In Stage II, 41 experts with a minimum of five years of experience in yoga therapy were invited for yoga module validation. The usefulness of the practices was rated by experts on a 3-point scale (1: not at all useful, 2: moderately useful, and 3: very much useful). The Lawshe content validity ratio (CVR) method was used for the content validity of the yoga module. Practices with a CVR score of > 0.3 were retained in the final yoga module. In Stage III, a certified yoga instructor administered the validated yoga module to 19 AS patients (average age: 35.5 ± 10.7 years) thrice weekly for a month. Feasibility was assessed on the basis of the attrition rate, retention rate, attendance of the participants, and the subjective response on practical sessions using a structured checklist.

RESULTS

Of the 41 practices in the module, 31 had a CVR score of > 0.3 and were included in the final yoga module. Of the 25 participants, 19 (76%) completed the study while six dropped out (24%). Nineteen patients reported greater improvement in pain and flexibility. They found yoga relaxing and easy to practice. Most participants (65%) were able to practice a minimum of 30 min/day.

CONCLUSION

The present study offers a validated yoga module consisting of 31 practices for AS patients. The results of the pilot suggested that the module is feasible, acceptable, and easy to practice for AS patients. We recommend that AS patients should practice this yoga module for a minimum of 30 min every day under the supervision of a yoga expert.

The Role of Yoga in Treating Stress-Related Symptoms in Dental Hygiene Students

Context:

Research has provided evidence for yoga's effectiveness in the prevention and treatment of pain and stress, both of which have been implicated as significant negative moderators of student performance and experience.

Aims:

This study investigated the feasibility and preliminary impact of a 10-week yoga intervention with dental hygiene students to reduce perceptions of stress and stress-related symptoms.

Settings and Design:

Students self-selected into a yoga treatment versus control condition. They completed stress and pain measures at four time points during and after the intervention or control period of 10-weeks.

Methods:

Participants were students enrolled in a dental hygiene program. All 77 participants completed a 10-week study, self-selecting into an intervention or control group. They completed three self-report questionnaires assessing pain and stress, administered at baseline, mid-point, postintervention, and two follow-ups. The 10-week yoga intervention consisted of 10 90-min yoga sessions that provided check-ins, breathing exercises, sequences of postures, relaxation exercises, and closing meditations.

Statistical Analysis Used:

Independent samples t-tests were used to compare perceived stress levels of participants in the control versus treatment groups. Paired t-test was used to assess differences in stress-related symptom levels across time.

Results:

Results suggested that a yoga intervention is feasible for this group and that active yoga practice can lower perceived stress across multiple domains and across time.

Conclusions:

A specially adapted and designed 10-week yoga protocol appears to be an accessible option for dental hygiene programs that seek to support their students in improving overall wellbeing.

Yoga-based intervention in patients with somatoform disorders: an open label trial

Somatoform disorders are common mental disorders associated with impaired functioning and increased utilization of health resources. Yoga-based interventions have been used successfully for anxiety, depression, and chronic pain conditions. However, literature on the use of yoga in treatment of somatoform disorders is minimal. The current study assessed the effect of a specific yoga-based intervention in patients with somatoform disorders. Consenting patients meeting ICD-10 criteria for somatoform disorders were offered a specific yoga module (1 h per day) as a treatment. Assessments including Visual Analogue Scale (VAS), Brief Pain Inventory (BPI), and others were carried out at baseline and after 2, 6, and 12 weeks. Sixty-four subjects were included in the study and 34 completed 12 weeks follow-up. Significant improvement was noted in pain severity from baseline to 12 weeks after regular yoga sessions. The mean VAS score dropped from 7.24 to 2.88. Worst and average pain score in the last 24 h on BPI dropped from 7.71 to 3.26 and from 6.12 to 2.0,7 respectively. Results of the study suggest that yoga-based intervention can be one of the non-pharmacological treatment options in somatoform disorders. These preliminary findings need replication in larger controlled studies.

Expectations and effects of a single yoga session on pain perception

Background:

Several studies show yoga may benefit chronic pain management. We investigated the effect of a single yoga session on the perception of pain, measured by a standardized pain provocation test in healthy yoga participants while also comparing pain perception to participants’ own expectations.

Materials and Methods:

Ninety yoga participants were recruited at hatha yoga schools in Switzerland. Pain perception was measured with a standardized algometric pain provocation test; i.e., a calibrated peg was applied for 10 seconds after which the participant rated pain intensity on a 0–10 numerical rating scale. The test was applied to the middle finger, ear lobe, and second toe before and after a 60-minute yoga session.

Results:

Sixty out of 90 (66.7%) yoga participants expected a reduced pain perception after the yoga session. However, 36 (40%) participants actually experienced less pain after compared to before the yoga session. But overall, pain perception statistically did not significantly change from before to after the yoga session at any of the three body locations assessed. The expectations and also the previous yoga experience did not significantly influence the participants’ pain perception.

Conclusions:

Regardless of the high positive expectations on the influence of yoga on pain, a single yoga session does not significantly influence pain perception induced by a pain provocation test. Hypoalgesic effects of yoga should be explained otherwise.

Relief from Back Pain Through Postural Adjustment: a Controlled Clinical Trial of the Immediate Effects of Muscular Chains Therapy (MCT)

Introduction

Back pain can be one of the most common health problems, causing suffering, disabilities, and financial losses. Postural models for pain treatment state that poor posture alters the joint position and causes pain, such as back pain. Muscular Chain Therapy (MCT) is a technique that is used to treat posture pathologies, among others.

Purpose

The aim of the present study was to assess the efficiency of a single session of Muscular Chain Therapy (MCT) on complaints of undiagnosed musculoskeletal spinal pain.

Setting

Physical therapy clinic of the University of Center-West (Guarapuava, Brazil).

Participants

100 subjects, aged between 20 and 39 years, with complaints of spinal musculoskeletal pain.

Research Design

Randomized controlled trial.

Intervention

The participants were randomly assigned by a non-care provider into two groups: The MCT Group that received Muscular Chain Treatment and the Control Group that received a placebo treatment of 15 minutes turned off ultrasound therapy. All volunteers were assessed before and after treatment using an analog pain scale. A score of 0 indicated no pain and 10 was the maximum degree of pain on the scale.

Main Outcome Measure

Degree of pain measured by analog scale

Results

The chi-square goodness of fit test was used to compare gender distribution among groups displayed a p value = .25. Subject age had differences analyzed using the unpaired t test (p = .44). Pain assessment for treatment and placebo control groups was analyzed using a paired t test and unpaired t test. The paired t test was used for intragroup before/after treatment comparison (MCT p = .00001; Control Group p = .0001). The unpaired t test was used for comparing the difference of the pain level before and after treatment between groups (p = .0001). A priori statistical significance was set a p = .05.

Conclusion

It is possible to conclude that one MCT session is an effective treatment of undiagnosed spinal musculoskeletal pain.

Characteristics of randomized controlled trials of yoga: a bibliometric analysis

Background

A growing number of randomized controlled trials (RCTs) have investigated the therapeutic value of yoga interventions. This bibliometric analysis aimed to provide a comprehensive review of the characteristics of the totality of available randomized yoga trials.

Methods

All RCTs of yoga were eligible. Medline/PubMed, Scopus, the Cochrane Library, IndMED, and the tables of content of yoga specialty journals not listed in medical databases were screened through February 2014. Bibliometric data, data on participants, and intervention were extracted and analyzed descriptively.

Results

Published between 1975 and 2014, a total of 366 papers were included, reporting 312 RCTs from 23 different countries with 22,548 participants. The median study sample size was 59 (range 8–410, interquartile range = 31, 93). Two hundred sixty-four RCTs (84.6%) were conducted with adults, 105 (33.7%) with older adults and 31 (9.9%) with children. Eighty-four RCTs (26.9%) were conducted with healthy participants. Other trials enrolled patients with one of 63 varied medical conditions; the most common being breast cancer (17 RCTs, 5.4%), depression (14 RCTs, 4.5%), asthma (14 RCTs, 4.5%) and type 2 diabetes mellitus (13 RCTs, 4.2%). Whilst 119 RCTs (38.1%) did not define the style of yoga used, 35 RCTs (11.2%) used Hatha yoga and 30 RCTs (9.6%) yoga breathing. The remaining 128 RCTs (41.0%) used 46 varied yoga styles, with a median intervention length of 9 weeks (range 1 day to 1 year; interquartile range = 5, 12). Two hundred and forty-four RCTs (78.2%) used yoga postures, 232 RCTs (74.4%) used breath control, 153 RCTs (49.0%) used meditation and 32 RCTs (10.3%) used philosophy lectures. One hundred and seventy-four RCTs (55.6%) compared yoga with no specific treatment; 21 varied control interventions were used in the remaining RCTs.

Conclusions

This bibliometric analysis presents the most complete up-to-date overview on published randomized yoga trials. While the available research evidence is sparse for most conditions, there was a marked increase in published RCTs in recent years.
