Video-game based exercises for older people with chronic low back pain: a protocol for a feasibility randomised controlled trial (the GAMEBACK trial)

Effects of an 8-Week Virtual Reality Training Program on Pain, Fall Risk, and Quality of Life in Elderly Women with Chronic Low Back Pain: Double-Blind Randomized Clinical Trial

Objective: Low back pain (LBP) and falls are among the major problems experienced by the elderly population. The present study investigated the effectiveness of an 8-week virtual reality training (VRT) program in helping relieve pain, minimize fall risk, and improve quality of life (QoL) in elderly women suffering from chronic LBP (CLBP). Materials and Methods: Twenty-five elderly women (VRT/intervention group = 13, control group = 12) with CLBP and aged 65 to 75 years were recruited. The VRT involved three 30-minute weekly sessions of exercises that were carried out using the Xbox Kinect headset. Pain intensity, fall risk, and QoL were assessed via the Visual Analog Scale, the Biodex Balance System, and the 36-Item Short Form Health Survey, respectively. Results: The outcomes of a one-way analysis of covariance indicated that the pain intensity score of the intervention group significantly decreased after participation in the VRT program (P = 0.001). The intervention group also showed reduced fall risk (P = 0.001) and elevated QoL (P = 0.001). Conclusion: The results confirmed that the VRT program can be regarded as a valid therapeutic intervention that helps reduce patients' symptoms and increase the effectiveness of exercises in the elderly by teaching pain-related insight as well as enhancing QoL and reduce fall risk through various movements.

The Use of Virtual Reality in Back Pain Rehabilitation: A Systematic Review and Meta-Analysis

This systematic review aimed to synthesize the existing evidence of extended reality (XR) on pain and motor function outcomes in patients with back pain. Following the Cochrane guidelines, relevant articles of any language were selected by 2 independent reviewers from CINAHL, Cochrane, Embase, Medline and Web of Knowledge databases. Of 2,050 unique citations, 24 articles were included in our review. These studies included a total of 900 back pain patients. Despite broader XR search, all interventions were virtual reality (VR) based and involved physical exercises (n = 17, 71%), hippotherapy (n = 4, 17%), motor imagery (n = 1, 4%), distraction (n = 1, 4%), and cognitive-behavior therapy (n = 1, 4%). Sixteen controlled studies were included in a meta-analysis which suggested that VR provides a significant improvement in terms of back pain intensity over control interventions (Mean Difference: -0.67; 95% CI: -1.12 to -0.23; I² = 85%). Almost all included studies presented high risk of bias, highlighting the need to improve methodology in the examination of VR interventions. While the specific set of studies showed high heterogeneity across several methodological factors, a tentative conclusion could be drawn that VR was effective improving back pain intensity and tends to have a positive effect on improving other pain outcomes and motion function. PERSPECTIVE: Extended reality technologies have appeared as interesting nonpharmacological options for the treatment of back pain, with the potential to minimise the need for opioid medications. Our systematic review summarised existing applications of extended reality for back pain and proposed a few recommendations to direct further studies in the field.

Advanced rehabilitation technology in orthopaedics-a narrative review

INTRODUCTION

As the demand for rehabilitation in orthopaedics increases, so too has the development in advanced rehabilitation technology. However, to date, there are no review papers outlining the broad scope of advanced rehabilitation technology used within the orthopaedic population. The aim of this study is to identify, describe and summarise the evidence for efficacy for all advanced rehabilitation technologies applicable to orthopaedic practice.

METHODS

The relevant literature describing the use of advanced rehabilitation technology in orthopaedics was identified from appropriate electronic databases (PubMed and EMBASE) and a narrative review undertaken.

RESULTS

Advanced rehabilitation technologies were classified into two groups: hospital-based and home-based rehabilitation. In the hospital-based technology group, we describe the use of continuous passive motion and robotic devices (after spinal cord injury) and their effect on improving clinical outcomes. We also report on the use of electromagnetic sensor technology for measuring kinematics of upper and lower limbs during rehabilitation. In the home-based technology group, we describe the use of inertial sensors, smartphones, software applications and commercial game hardware that are relatively inexpensive, user-friendly and widely available. We outline the evidence for videoconferencing for promoting knowledge and motivation for rehabilitation as well as the emerging role of virtual reality.

CONCLUSIONS

The use of advanced rehabilitation technology in orthopaedics is promising and evidence for its efficacy is generally supportive.

Family History Influences the Effectiveness of Home Exercise in Older People With Chronic Low Back Pain: A Secondary Analysis of a Randomized Controlled Trial

OBJECTIVE

To investigate whether a family history of low back pain (LBP) influences patient outcomes and treatment effects following home exercises in older people with chronic LBP.

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Local community.

PARTICIPANTS

People older than 55 years with chronic LBP (N=60).

INTERVENTIONS

Participants in the intervention group completed video game exercises for 60 minutes 3 times per week for 8 weeks. Participants in the control group were instructed to maintain their usual levels of activity and care seeking behaviors.

MAIN OUTCOMES MEASURES

Participants indicated whether any of their immediate family members had a history of "any" LBP or "activity-limiting" LBP at baseline. We collected self-reported measures of pain, function, pain self-efficacy, care seeking, physical activity, disability, fear of movement and/or reinjury, and falls efficacy at baseline, 8 weeks, 3 months, and 6 months. We performed regression analyses to determine whether a family history of LBP predicted patient outcomes and moderated the effects of home exercise.

RESULTS

Participants with a family history of any LBP were less likely to be highly active than those without a family history (odds ratio, 0.08; 95% CI, 0.01-0.42; P=.003). Home-based video game exercises led to improvements in function in those without a family history of activity-limiting LBP (β=1.78; 95% CI, 0.56-3.00; P=.006) but not in those with a family history (β=-0.17; 95% CI, -2.56 to 2.21; P=.880) (interaction P=.049). A family history of LBP did not influence the remaining patient outcomes or treatment effects.

CONCLUSIONS

A family history of LBP appears to negatively influence physical activity levels in older people with chronic LBP. Further, home-based video game exercises appear to be beneficial for older people with chronic LBP that do not have a family history of LBP.

Video-Game-Based Exercises for Older People With Chronic Low Back Pain: A Randomized Controlledtable Trial (GAMEBACK)

Background

Video game technology increases adherence to home exercise and could support self-management for older people with chronic low back pain (LBP).

Objective

The objective was to investigate the effects of home-based video game exercises on pain self-efficacy and care-seeking in older people with chronic LBP.

Design

The study was a randomized controlled trial.

Setting

The setting was a community and waiting list.

Participants

Sixty participants, aged > 55 years with chronic LBP, were randomized (1:1) to Wii Fit U exercises or to continue their usual activities for 8 weeks.

Intervention

The intervention was home-based Wii Fit U flexibility, strengthening, and aerobic exercises for 60 minutes, 3 times per week, with fortnightly calls from a physical therapist.

Measurements

Measurements included pain self-efficacy and care-seeking (primary outcomes), and physical activity, pain, function, disability, fear of movement/reinjury, falls efficacy, recruitment and response rates, adherence, experience with the intervention, and adverse events (secondary outcomes).

Results

The mean age of participants was 67.8 (standard deviation = 6.0) years. Adherence to the total recommended exercise time was 70.8%, and no adverse events were reported. Participants completing Wii Fit U exercises had significantly higher pain self-efficacy at 6 months, but not immediately postintervention or at 3 months; there were no between-group differences in care-seeking. Compared with the control group, participants completing Wii Fit U exercises demonstrated significantly greater improvements in pain and function at 8 weeks and were more likely to engage in flexibility exercises at 6 months. There were no significant between-group differences for the remaining outcomes.

Limitations

Participants and therapists were not blinded.

Conclusions

Wii Fit U exercises improved pain self-efficacy at 6 months, and pain and function immediately postintervention in older people with chronic LBP, but the clinical importance of these changes is questionable. Wii Fit U exercises had no effect on care-seeking, physical activity, disability, fear of movement/reinjury, or falls efficacy.
