Adherence to home exercises in non-specific low back pain. A randomised controlled pilot trial

Understanding social determinants of health and physical therapy outcomes in patients with low back pain: A scoping review

BACKGROUND

Low back pain (LBP) is the number one cause of disability worldwide; however, it is not clear how social determinants of health (SDOH) impact care management and outcomes related to physical therapy (PT) services for patients with LBP.

OBJECTIVE

The purposes of this scoping review are to examine and assimilate the literature on how SDOH and PT care relate to non-specific LBP outcomes and identify gaps in the literature to target for future research.

METHODS

Data were extracted from eight electronic databases from January 2011 to February 2022. Reviewers independently screened all studies using the PRISMA extension for scoping review guidelines. Data related to study design, type of PT, type of non-specific LBP, patient demographics, PT intervention, SDOH, and PT outcomes were extracted from the articles.

RESULTS

A total of 30,523 studies were screened, with 1961 articles undergoing full text review. Ultimately, 76 articles were identified for inclusion. Sex and age were the most frequent SDOH examined (88% and 78% respectively) followed by education level (18%). Approximately half of the studies that examined age, sex, and education level identified no effect on outcomes. The number of studies examining other factors was small and the types of outcomes evaluated were variable, which limited the ability to pool results.

CONCLUSIONS

Sex and age were the most frequent SDOH examined followed by education level. Other factors were evaluated less frequently, making it difficult to draw conclusions. Study design and heterogeneity of determinants and outcomes were barriers to examining the potential impact on patients with LBP.

How do non-specific back pain patients think about their adherence to physiotherapy, and what strategies do physiotherapists use to facilitate adherence? A focus group interview study

BACKGROUND

Long-term effectiveness of physiotherapy (PT) for low back pain (LBP) depends on the adherence of patients. Objectives: (1) Identify aspects associated with the adherence of patients with LBP to physiotherapy, and (2) identify factors to facilitate adherence of patients with LBP to PT.

METHOD

Focus group interviews were conducted with 10 patients with LBP (n = 10, 5 women) and 11 physiotherapists (5 women) from Germany and Switzerland, treating patients with LBP. Data analysis was based on structured content analysis. Deductive and inductive categories were identified and coded.

RESULTS

Patients with LBP requested more and effective home programs, long-term rehabilitation management, and individualized therapy to achieve a higher level of adherence. Physiotherapists requested more time for patient education. Communication, quality of the therapist-patient relationship, and individualized therapy were identified as essential factors by both representatives.

CONCLUSION

Patients and physiotherapists identified aspects contributing to adherence. These may guide the development of multidimensional measurement tools for adherence. In addition, this information can be used to develop PT approaches to facilitate the level of adherence.

Usability of a visual feedback system to assess and improve movement disorders related to neck pain: Perceptions of physical therapists and patients

A prototype visual feedback system has been developed to assess and improve movement disorders related to neck pain. The aim of this study was to assess the usability of the prototype in a rehabilitation setting. Twelve physical therapists integrated the device into their regular therapy programs for 24 neck pain patients with movement disorders. Each patient performed three individual therapy sessions with the device under physical therapist supervision. Usability was assessed by the physical therapists and patients using therapy diaries, the System Usability Scale, and focus group or personal interviews. Based on an overall usability rating of marginally acceptable, the visual feedback system was generally found to be a device with the potential to assess and train neck pain patients but needs improvement. To become a useful adjunct to regular physical therapy, improvements in the hardware and software, and further system developments are required.

Strategies to facilitate and tools to measure non-specific low back pain patients' adherence to physiotherapy - A two-stage systematic review

BACKGROUND

Sustainable management for non-specific low back pain relies on adherence. This requires effective strategies to facilitate but also tools to measure adherence to physiotherapy.

OBJECTIVE

This two-stage systematic review aims to identify (1) tools to measure non-specific back pain patients' adherence to physiotherapy and (2) the most effective strategy to facilitate patients' adherence to physiotherapy.

METHOD

PubMed, Cochrane, PEDro, and Web of Science were searched for English language studies measuring adherence in adults with low back pain. Following PRISMA recommendations, scoping review methods were used to identify measurement tools (stage 1). The effectiveness of interventions (stage 2), followed a predefined systematic search strategy. Two independent reviewers selected eligible studies (software Rayyan), analyzed these for risk of bias using the Downs and Black checklist. Data relevant to assess adherence were collected in a predesigned data extraction table. Results were heterogeneous and hence summarized narratively.

RESULTS

Twenty-one studies were included for stage 1 and 16 for stage 2. Identified were 6 different tools to measure adherence. The most used tool was an exercise diary; the most common more multidimensional tool was the Sports Injury Rehabilitation Adherence Scale. Most included studies were not designed to improve or measure adherence but used adherence as a secondary outcome for new exercise programs. The most promising strategies for facilitating adherence were based on cognitive behavioral principles.

CONCLUSION

Future studies should focus on the development of multidimensional strategies to facilitate adherence to physiotherapy and appropriate tools to measure all aspects of adherence.

Multimedia Instructions for Motor Control Exercises in Patients With Chronic Nonspecific Low Back Pain

BACKGROUND

Low back pain (LBP) is one of the top 3 diseases that may lead to disability. Current treatment guidelines define exercise as a first-line treatment for nonspecific LBP (NSLBP). There are various evidence-based exercise approaches for treating NSLBP, and many of them include motor control principles. Motor control exercises (MCEs) are better than general exercises that do not include motor control principles. Many patients find learning these exercises complex and challenging, in that MCE exercises have no standard teaching method. The researchers of this study developed multimedia instructions for an MCE program to make teaching MCE easier; thus, more effective.

METHODS

The participants were randomized into multimedia or standard (face-to-face) instruction groups. We applied the same treatments to both groups at the same dosage. The only differences between groups were the exercise instruction methods. The multimedia group learned MCE from multimedia videos; the control group learned MCE from a physiotherapist with face-to-face instructions. Treatment lasted 8 weeks. We evaluated patients' exercise adherence with Exercise Adherence Rating Scale (EARS), pain with the Visual Analog Scale, and disability with Oswestry Disability Index. Evaluations were made before and after treatment. Follow-up evaluations were carried out 4 weeks after the end of treatment.

RESULTS

There was no statistically significant interaction between the group and time on pain, F2,56 = 0.068, P = .935, partial η2 = .002 and Oswestry Disability Index scores, F2,56 = 0.951, P = .393, partial η2 = .033. Also, there was no statistically significant interaction between the group and time on Exercise Adherence Rating Scale total scores F1,20 = 2.343, P = .142, partial η2 = .105.

CONCLUSIONS

This study showed that multimedia instructions for MCE have similar effects to standard (face-to-face) instructions on pain, disability, and exercise adherence in patients with NSLBP. To our knowledge, with these results, the developed multimedia instructions became the first free, evidence-based instructions that have objective progression criteria and a Creative Commons license.

Sensor-based intervention to enhance movement control of the spine in low back pain: Protocol for a quasi-randomized controlled trial

Introduction

Chronic low back pain is a common condition that imposes an enormous burden on individuals and society. Physical exercise with education is the most effective treatment, but generally results in small, albeit significant improvements. However, which type of exercise is most effective remains unknown. Core stability training is often used to improve muscle strength and spinal stability in these patients. The majority of the core stability exercises mentioned in intervention studies involve no spinal movements (static motor control exercises). It is questionable if these exercises would improve controlled movements of the spine. Sensor-based exergames controlled with spinal movements could help improve movement control of the spine. The primary aim of this study is to compare the effects of such sensor-based exergames to static motor control exercises on spinal movement control.

Methods and analysis

In this quasi-randomized controlled trial, 60 patients with chronic low back pain who are already enrolled in a multidisciplinary rehabilitation programme will be recruited. Patients will be randomly allocated into one of two groups: the Sensor-Based Movement Control group (n = 30) or the Static Motor Control group (n = 30). Both groups will receive 8 weeks of two supervised therapy sessions and four home exercises per week in addition to the rehabilitation programme. At baseline (week 1) and after the intervention (week 10), movement control of the spine will be assessed using a tracking task and clinical movement control test battery. Questionnaires on pain, disability, fear avoidance and quality of life will be taken at baseline, after intervention and at 6- and 12 months follow-up. Repeated measures ANOVAs will be used to evaluate if a significant Group x Time interaction effect exists for the movement control evaluations.

Discussion

Sensor-based spinal controlled exergames are a novel way to train spinal movement control using meaningful and engaging feedback. The results of this study will inform clinicians and researchers on the efficacy of movement control training for patients with low back pain.

Ethics and dissemination

Ethical approval for this study protocol was obtained from the METC Brabant (protocol number NL76811.028.21).

Feedback on Trunk Movements From an Electronic Game to Improve Postural Balance in People With Nonspecific Low Back Pain: Pilot Randomized Controlled Trial

Background

Postural balance is compromised in people with low back pain, possibly by changes in motor control of the trunk. Augmenting exercising interventions with sensor-based feedback on trunk posture and movements might improve postural balance in people with low back pain.

Objective

We hypothesized that exercising with feedback on trunk movements reduces sway in anterior-posterior direction during quiet standing in people with low back pain. Secondary outcomes were lumbar spine and hip movement assessed during box lift and waiter bow tasks, as well as participant-reported outcomes. Adherence to the exercising intervention was also examined.

Methods

A randomized controlled trial was conducted with the intervention group receiving unsupervised home exercises with visual feedback using the Valedo Home, an exergame based on 2 inertial measurement units. The control group received no intervention. Outcomes were recorded by blinded staff during 4 visits (T1-T4) at University Hospital Zurich. The intervention group performed 9 sessions of 20 minutes in the 3 weeks between T2 and T3 and were instructed to exercise at their own convenience between T3 and T4. Postural balance was assessed on a force platform. Lumbar spine and hip angles were obtained from 3 inertial measurement units. The assessments included pain intensity, disability, quality of life, and fear of movement questionnaires.

Results

A total of 32 participants with nonspecific low back pain completed the first assessment T1, and 27 (84%) participants were randomized at T2 (n=14, 52% control and n=13, 48% intervention). Intention-to-treat analysis revealed no significant difference in change in anterior-posterior sway direction during the intervention period with a specified schedule (T2-T3) between the groups (W=99; P=.36; r=0.07). None of the outcomes showed significant change in accordance with our hypotheses. The intervention group completed a median of 61% (55/90; range 2%-99%) of the exercises in the predefined training program. Adherence was higher in the first intervention period with a specified schedule.

Conclusions

The intervention had no significant effect on postural balance or other outcomes, but the wide range of adherence and a limited sample size challenged the robustness of these conclusions. Future work should increase focus on improving adherence to digital interventions.

A vision for the future of wearable sensors in spine care and its challenges: narrative review

OBJECTIVE

This review aimed to: (I) provide a brief overview of some topical areas of current literature regarding applications of wearable sensors in the management of low back pain (LBP); (II) present a vision for a future comprehensive system that integrates wearable sensors to measure multiple parameters in the real world that contributes data to guide treatment selection (aided by artificial intelligence), uses wearables to aid treatment support, adherence and outcome monitoring, and interrogates the response of the individual patient to the prescribed treatment to guide future decision support for other individuals who present with LBP; and (III) consider the challenges that will need to be overcome to make such a system a reality.

BACKGROUND

Advances in wearable sensor technologies are opening new opportunities for the assessment and management of spinal conditions. Although evidence of improvements in outcomes for individuals with LBP from the use of sensors is limited, there is enormous future potential.

METHODS

Narrative review and literature synthesis.

CONCLUSIONS

Substantial research is underway by groups internationally to develop and test elements of this system, to design innovative new sensors that enable recording of new data in new ways, and to fuse data from multiple sources to provide rich information about an individual's experience of LBP. Together this system, incorporating data from wearable sensors has potential to personalise care in ways that were hitherto thought impossible. The potential is high but will require concerted effort to develop and ultimately will need to be feasible and more effective than existing management.

SOME ASPECTS OF THE POTENTIAL ADHERENCE TO REHABILITATION OF PATIENTS WITH MUSCULOSKELETAL INJURIES

OBJECTIVE

The aim: To investigate and analyse certain aspects of potential adherence to rehabilitation treatment of patients with musculoskeletal injuries.

PATIENTS AND METHODS

Materials and methods: The study was conducted among 108 patients with musculoskeletal injuries. A questionnaire, containing 25 questions, was used to determine the importance for patients of rehabilitation treatment and their readiness to perform its measures.

RESULTS

Results: It was found that for 98.0 ± 2.6% of surveyed patients with injuries it is important not to experience limitations in the future functioning of their bodies. 97.2 ± 3.1% of the surveyed patients with injuries indicated their readiness to do exercises prescribed by a rehabilitation specialist at home, and 87.0 ± 6.3% were ready to perform physical exercises even in case of unpleasant sensations or discomfort. It was determined that 67.6 ± 8.8% of the surveyed patients with injuries are ready to attend rehabilitation classes with specialists, 69.5 ± 8.7% are ready to record their own achievements at home and 73.1 ± 8.4% of the patients consent to maintain regular contact with rehabilitation specialists via the Internet.

CONCLUSION

Conclusions: Patients with musculoskeletal injuries have a high level of understanding of the importance of rehabilitation. The vast majority of them are ready to perform most of the components of rehabilitation, but without significant changes in normal life and with a predominant stay at home. All this requires the development of organizational measures to form the adherence to particular components of rehabilitation.

Exergaming Using Postural Feedback From Wearable Sensors and Exercise Therapy to Improve Postural Balance in People With Nonspecific Low Back Pain: Protocol for a Factorial Pilot Randomized Controlled Trial

Background

Physical exercise is a common treatment for people with low back pain (LBP). Wearable sensors that provide feedback on body movements and posture during exercise may enhance postural balance and motor control in people with LBP.

Objective

This study aims to investigate whether physical exercising with postural feedback (EPF) improves postural balance, motor control, and patient-reported outcomes in people with LBP.

Methods

The study was an assessor-blinded 2×2 factorial trial. We planned to recruit 80 participants with nonspecific LBP who did not receive treatment for LBP. In addition, we aimed to recruit 40 patients with chronic, nonspecific LBP who were receiving exercise therapy (ET) at the University Hospital Zurich. Both ET patients and participants without treatment were randomized to receive either an additional EPF intervention or no additional intervention. This resulted in four different combinations of interventions: ET+EPF, ET, EPF, and no intervention. The participants underwent outcome assessments at inclusion (T1); 3 weeks later, at randomization (T2); after an intervention period of 3 weeks with a predefined exercise schedule for participants receiving EPF (T3); and after an additional 6 weeks, during which participants assigned to the EPF groups could exercise as much as they wished (T4). Patients receiving ET completed their regularly prescribed therapies during the study period. Balance was assessed during quiet standing on a force platform, and motor control was assessed during a lifting task and a waiter’s bow task. Physical activity was recorded using an activity tracker and the participants’ mobile phones during the study. The predefined EPF schedule consisted of nine sessions of 20 minutes of exercise with a tablet and inertial measurement unit sensors at home. Participants performed a series of trunk and hip movements and received feedback on their movements in a gamified environment displayed on the tablet.

Results

The first participant was recruited in May 2019. Data collection was completed in October 2020, with 3 patients and 32 eligible people without therapy who passed the eligibility check.

Conclusions

Although it will not be possible to investigate differences in patients and people without other therapies, we expect this pilot study to provide insights into the potential of EPF to improve balance in people with LBP and adherence to such interventions.

Factors associated with exercise adherence to prevent or treat neck and low back pain: A systematic review

BACKGROUND

Much attention has been paid to the evaluation of the efficacy of exercise therapy or increasing physical activity with the aim to prevent or alleviate neck and low back pain. However, exercise adherence is necessary for the effective management of neck and low back pain.

OBJECTIVE

We aimed to systematically review randomized controlled trials and cohort studies to gain insights into the factors associated with adherence to exercise or physical activity programs to prevent or treat neck pain and low back pain.

METHOD

Publications were systematically searched from 1980-December 2019 in several databases. The following key words were used: neck pain or low back pain paired with exercise or physical activity and adherence or compliance. Relevant studies were retrieved and assessed for methodological quality by two independent reviewers. Quality of evidence was assessed and rated according to GRADE guidelines.

RESULTS

Nine randomized controlled trials and eight cohort studies were included in this review. Randomized controlled trials indicated moderate-quality evidence for the association between exercise adherence and self-efficacy. Cohort studies showed moderate-quality evidence for the association between exercise adherence and education level.

CONCLUSIONS

Literature investigating factors associated with exercise adherence to prevent or treat neck and low back pain was heterogeneous. Few factors were found to be associated with exercise adherence. More studies are needed before any firm conclusions can be reached.

Instrumented trunk impairment scale (iTIS): A reliable measure of trunk impairment in the stroke population

BACKGROUND

The Trunk Impairment Scale (TIS) is recommended for use in clinical research to assess trunk impairment post-stroke. However, it is observer dependent and does not consider the quality of trunk movement. To address these challenges, this study proposes an instrumented TIS (iTIS).

OBJECTIVE

This study aims to investigate the intra-rater and inter-rater reliability of the iTIS in chronic stroke patients.

METHOD

Trunk impairment was assessed in 20 patients with stroke using the iTIS Valedo system; three sensors were fixed to the skin on the sternum, L1 and S1 levels. Interclass correlation coefficients were used to assess the inter-rater and intra-rater reliability (between days) with 95% CI.

RESULTS

Reliability for the dynamic subscale parameters was good to excellent (intra-rater ICC = 0.60-0.95; inter-rater ICC = 0.59-0.93); however, reliability for the coordination parameters was poor to good (intra-rater ICC = 0.05-0.72) and poor to excellent (inter-rater ICC = 0.04-0.78).

CONCLUSION

The iTIS demonstrates an acceptable level of reliability for dynamic subscale measurement in research and clinical practice. Further studies could use larger sample sizes and improve the iTIS methodology by employing additional sensors on the limbs to detect compensatory movements.

Concurrent Validity of a Novel Wireless Inertial Measurement System for Assessing Trunk Impairment in People with Stroke

Background: The Trunk Impairment Scale (TIS) is recommended for clinical research use to assess trunk impairment post-stroke. However, it is observer-dependent and neglects the quality of trunk movements. This study proposes an instrumented TIS (iTIS) using the Valedo system, comprising portable inertial sensors, as an objective measure of trunk impairment post-stroke. Objective: This study investigates the concurrent and discriminant ability of the iTIS in chronic stroke participants. Method: Forty participants (20 with chronic stroke, 20 healthy, age-matched) were assessed using the TIS and iTIS simultaneously. A Spearman rank correlation coefficient was used to examine concurrent validity. A ROC curve was used to determine whether the iTIS could distinguish between stroke participants with and without trunk impairment. Results: A moderate relationship was found between the observed iTIS parameters and the clinical scores, supporting the concurrent validity of the iTIS. The small sample size meant definitive conclusions could not be drawn about the parameter differences between stroke groups (participants scoring zero and one on the clinical TIS) and the parameter cut-off points. Conclusion: The iTIS can detect small changes in trunk ROM that cannot be observed clinically. The iTIS has important implications for objective assessments of trunk impairment in clinical practice.

Abstracts of low back pain trials are poorly reported, contain spin of information and are inconsistent with the full text: An overview study

OBJECTIVE

To investigate trials abstracts evaluating treatments for low back pain with regards to completeness of reporting, spin (i.e., interpretation of study results that overemphasizes the beneficial effects of the intervention), and inconsistencies in data with the full text.

DATA SOURCES

The search was performed on Physiotherapy Evidence Database (PEDro) in February 2016.

STUDY SELECTION

This is an overview study of a random sample of 200 low back pain trials published between 2010 and 2015. The languages of publication were restricted to English, Spanish and Portuguese.

DATA EXTRACTION

Completeness of reporting was assessed using the CONSORT for Abstracts checklist (CONSORT-A). Spin was assessed using a SPIN-checklist. Consistency between abstract and full text were assessed by applying the assessment tools to both the abstract and full text of each trial and calculating inconsistencies in the summary score (paired t test) and agreement in the classification of each item (Kappa statistics). Methodological quality was analyzed using the total PEDro score.

DATA SYNTHESIS

The mean number of fully reported items for abstracts using the CONSORT-A was 5.1 (SD 2.4) out of 15 points and the mean number of items with spin was 4.9 (SD 2.6) out of 7 points. Abstract and full text scores were statistically inconsistent (P=0.01). There was slight to moderate agreement between items of the CONSORT-A in the abstracts and full text (mean Kappa 0.20 SD 0.13) and fair to moderate agreement for items of the SPIN-checklist (mean Kappa 0.47 SD 0.09).

CONCLUSIONS

The abstracts were incomplete, with spin and inconsistent with the full text. We advise health care professionals to avoid making clinical decisions based solely upon abstracts. Journal editors, reviewers and authors are jointly responsible for improving abstracts, which could be guided by amended editorial policies.

Elastic Resistance Effectiveness on Increasing Strength of Shoulders and Hips

Picha, KJ, Almaddah, MR, Barker, J, Ciochetty, T, Black, WS, and Uhl, TL. Elastic resistance effectiveness on increasing strength of shoulders and hips. J Strength Cond Res 33(4): 931-943, 2019-Elastic resistance is a common training method used to gain strength. Currently, progression with elastic resistance is based on the perceived exertion of the exercise or completion of targeted repetitions; exact resistance is typically unknown. The objective of this study was to determine whether knowledge of load during elastic resistance exercise will increase strength gains during exercises. Participants were randomized into 2 strength training groups, elastic resistance only and elastic resistance using a load cell (LC) that displays force during exercise. The LC group used a Smart Handle (Patterson Medical Supply, Chicago, IL, USA) to complete all exercises. Each participant completed the same exercises 3 times weekly for 8 weeks. The LC group was provided with a set load for exercises, whereas the elastic resistance only group was not. The participant's strength was tested at baseline and program completion, measuring isometric strength for shoulder abduction (SAb), shoulder external rotation (SER), hip abduction (HAb), and hip extension (HEx). Independent t-tests were used to compare the normalized torques between groups. No significant differences were found between groups. Shoulder strength gains did not differ between groups (SAb p > 0.05; SER p > 0.05). Hip strength gains did not differ between groups (HAb p > 0.05; HEx p > 0.05). Both groups increased strength because of individual supervision, constantly evaluating degree of difficulty associated with exercise and providing feedback while using elastic resistance. Using an LC is as effective as supervised training and could provide value in a clinical setting when patients are working unsupervised.

The effectiveness of home-based exercise programs for low back pain patients

[Purpose] The purpose of this study was to investigate the effectiveness of home-based exercise programs for low back pain (LBP) patients. [Subjects and Methods] The study subjects were 49 volunteer chronic LBP patients. Home-based exercises that had been specifically modified for the individual patients were prescribed for a period of four weeks, and the volunteers were asked to return for a control evaluation at the end of this period. Exercise adherence and correct performance, pain intensity, disability, endurance, and flexibility were compared between pre- and post intervention, and correlations between exercise adherence and correct performance with, pain intensity score, endurance, disability, and flexibility were investigated. [Results] Twenty-eight patients (57.14%) did not return for the control evaluation. The mean age of the patients who participated in this control test was 43.24 ± 10.89 years. The adherence rate of the home exercise program was 54.10 ± 26.01%, and the correctly performed execises score was 2.7 ± 1.9. All of the parameters had improved at the final evaluation; however, there was no correlation among the parameters. [Conclusion] Clinicians should be aware of the patient’s adherence level when recommending home-based exercises, and should also realize that exercises might be performed inaccurately in an unsupervised environment.
