Effects of Exergames in Women with Fibromyalgia: A Randomized Controlled Study

Effects of Virtual Reality-Based Rehabilitation in the Treatment of Patients with Fibromyalgia Syndrome: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

The aim was to analyze the effects of virtual reality-based rehabilitation (VRBR) in patients with fibromyalgia syndrome (FMS). This systematic review and meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search was conducted in CINAHL, Medline (via PubMed), Scopus, and Web of Science up to January 2023. Eligibility criteria were defined with Participants, Interventions, Comparisons, Outcomes, and Study design. To assess the methodological quality, the modified Downs and Black scale was used. The risk of bias was assessed through The Cochrane Collaboration's tool. Meta-analysis was performed using RevMan software. Seventeen studies were included in the systematic review and 11 in the meta-analysis. We obtained significant differences in favor of VRBR for FMS impact (standardized mean difference or SMD: -0.49; 95% confidence interval or CI: -0.72 to -0.26), pain intensity (SMD: -0.50; 95% CI: -0.87 to -0.12), fatigue (SMD: -0.55, 95% CI: -0.89 to -0.22), depression (SMD: -0.39; 95% CI: -0.55 to -0.23), anxiety (SMD: -0.36; 95% CI: -0.57 to -0.14), health-related quality of life (SMD: 0.56; 95% CI: 0.29 to 0.83), health perception (mean difference or MD:10.56; 95% CI: 6.23 to 14.88), functional exercise capacity (SMD: 0.60; 95% CI: 0.33 to 0.87), and physical function (MD: 10.90; 95% CI: 7.04 to 14.77). No significant differences were found for kinesiophobia. VRBR significantly improves FMS symptoms, quality of life, and physical condition. VRBR applied alone or combined with other interventions shows good results. VRBR was superior to treatment as usual. Better results were obtained when specialized VRBR was used. More research is needed to determine how to implement this treatment and to study VRBR effects on follow-up.

An immersive virtual reality exergame as a patient education approach in fibromyalgia: Pilot study

Background

Immersive Virtual Reality (VR) has been applied in pain management for various conditions, but its use in fibromyalgia (FM) remains underexplored. While physical activity plays a role in treating FM, patients' low tolerance often limits its effectiveness. After reviewing the literature on VR and games for FM, we designed a novel VR exergame to assist FM patients in performing physical activity, and evaluate its feasibility.

Materials and Methods

This pilot study involved three female subjects with FM and four healthy female volunteers. The main outcomes included qualitative assessments of exertion, pain levels, psychological states experienced during the VR session, but also device comfort.

Results

Improvements in perceived exertion and pain intensity were observed during the VR exergame session in comparison to pre-exergame levels, along with a reduction in depression, stress and anxiety levels while using the VR immersive system. Most participants experienced also increase of relaxation and positive emotions during the exergame. Only one participant was not able to complete all levels of the exergame due to musculoskeletal pain exacerbation; nevertheless, this patient reported an improvement in motivation and enjoyment during the gameplay. Many participants expressed a greater motivation to perform the exercises in the VR environment compared to traditional training methods.

Conclusion

The proposed VR exergame is a feasible system that might reduce depression, stress and anxiety, while boosting motivation and relaxation in both healthy and FM subjects. A calibration protocol is required to tailor the system to each user's pain levels and physical abilities.

Effects of Traditional Chinese Martial Arts and Stretching Exercises on Symptoms of Fibromyalgia: A Systematic Review and Meta-Analysis

Fibromyalgia syndrome (FMS) is a chronic condition characterized by widespread musculoskeletal pain and various associated symptoms. Non-pharmacological interventions have gained attention for managing FMS and improving patient outcomes. We reviewed past research to investigate the effects of traditional Chinese martial arts (TCMA) and stretching training (ST) on symptoms of patients with FMS. We searched Web of Science, Medline via PubMed, the Cochrane Library, and EMBASE from their inceptions to June 1, 2023. Across selected studies, we evaluated TCMA and ST using Fibromyalgia Impact Questionnaire (FIQ) scores, pain symptoms, fatigue levels, and sleep quality as outcome measures. Compared with control groups, participants receiving TCMA and ST interventions showed significantly lower FIQ scores (Standard Mean Difference (SMD) = -3.01, 95% Confidence Interval (CI) [-4.83,-1.19]), improved pain symptoms (SMD = -0.77, 95% CI [-1.07,-0.47]), less fatigue (SMD = 1.31, 95% CI [0.50,2.11]), and enhanced sleep quality (SMD = -0.55, 95% CI [-0.97,-0.12]). Subgroup analyses revealed that, irrespective of intervention duration, both TCMA and ST interventions were effective in relieving pain symptoms in these patients. ST interventions showed significant improvement in fatigue symptoms, while TCMA interventions positively influenced sleep quality. These findings highlight potential non-pharmalogical benefits of TCMA and ST interventions in managing FMS. However, future research should explore the optimal duration, frequency, intensity, and types of interventions for TCMA and ST and design targeted exercise intervention programs to study the effects of these interventions on different characteristics of FMS patients. Attention should be given to the effects of short-term interventions on improving fatigue symptoms, sleep quality, and pain relief, to provide more personalized and effective FMS treatment plans.

The effectiveness of stretching exercises in patients with fibromyalgia: A systematic review

Fibromyalgia is one of the most prevalent chronic pain disorders. Fibromyalgia is characterised by generalised pain. In addition, patients with fibromyalgia often have co-morbidity. Since no cure is available, the treatment is based on symptom management, with physical exercise being the recommended first-line treatment. Different exercise modalities have been examined, including the practice of stretching exercises. The aim of the systematic review is to summarise the efficacy of stretching exercises on fibromyalgia symptoms and to study the content and the quality of the current evidence. The review followed the recommendations of the PRISMA statement. The search for articles was performed in April 2023. We searched on MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, AMED, PEDro, ClinicalTrials.gov and the Cochrane Collaboration Trials Register. The search was updated in March 2024. The protocol was registered in PROSPERO. Risk of Bias was assessed using the Cochrane Risk of Bias tool, and quality assessment was performed using the GRADE approach. In total, 2586 studies were found in the database searches, of which nine were included in the analysis. The primary outcome was pain. Secondary outcomes were self-reported quality of life, fatigue and physical and mental functioning. The available evidence shows that stretching exercises may improve pain, health-related quality of life and physical and mental functioning, but the level of evidence is low. The main limitation is due to issues with the heterogeneity of the interventions and small sample sizes. Trial registration: PROSPERO registration number CRD42023399614. Key Points • Stretching exercises show promise in the treatment of fibromyalgia. They may improve pain, health-related quality of life, physical functioning and mental health, but the level of evidence is low. • This study goes beyond previous research by presenting a more comprehensive and detailed analysis of the content and methodological quality of the current evidence. • Further research with clearly outlined protocols must be carried out to advance our understanding of the benefits of stretching exercises on fibromyalgia symptoms.

Effectiveness of manual lymphatic drainage in women with fibromyalgia: A pilot study

BACKGROUND

Currently there is no treatment capable of significantly alleviating all the symptoms of fibromyalgia (FM), even though it is a complex syndrome with a high prevalence in the population.

DESIGN

Experimental study using a single-blind, randomised, clinical trial.

OBJECTIVE

To analyse the efficacy of manual lymphatic drainage (MLD) as an alternative to traditional treatment of fibromyalgia (FM) in women.

METHODS

This was an experimental study using a single-blind, randomised, clinical trial of 20 women between 30 and 55 years old with FM. Patients were divided into an experimental group (n = 10) and a control group (n = 10). During the study, 3 measurements of pain (visual analogue scale and algometry), FM impact (Fibromyalgia Impact Questionnaire), sleep quality (Index Pittsburgh), anxiety and depression (Hospital Anxiety and Depression Scale) were recorded. Treatment of the experimental group consisted of 2 weekly MLD sessions for 6 weeks.

RESULTS

The effect of the interaction of MLD showed statistically significant results in Right intercostal space (F2,36 = 3.54; p = 0.04; n2p = 0.16). The sleep quality was significantly better favour of the treatment (F2,36 = 4.16; p = 0.01; n2p = 0.20).

CONCLUSIONS

MLD therapy demonstrated effects in the experimental group in contrast to the control group across the intervention period concerning the right intercostal space and sleep-related factors. However, MLD did not result in observable alterations in pain perception.

Effect of Exercise Interventions on Health-Related Quality of Life in Patients with Fibromyalgia Syndrome: A Systematic Review and Network Meta-Analysis

OBJECTIVE

Several guidelines highlight the beneficial impact of exercise on the management of symptoms and health-related quality of life (HRQOL) in patients with fibromyalgia syndrome (FMS). However, few analyses have compared different types of exercise. We, therefore, intent to compare the effects of different exercise types on improving the overall HRQOL and typical symptoms in patients with FMS.

METHODS

Medline, Embase, the Cochrane Register of Clinical Trials, and NIH ClinicalTrials.gov were searched from inception to April 21, 2022. Randomized clinical trials (RCTs) were included to assess the impact of exercise intervention on health parameters in adult FMS patients. Data were extracted independently and a frequentist network meta-analyses (NMA) was performed to rank the effects of interventions according to P-scores. The NMA evidence certainty was assessed using the method recommended by Grading of Recommendations Assessment, Development, and Evaluation Working Group.

RESULTS

A total of 57 RCTs were identified, including 3319 participants, involving 9 interventions (7 types of exercise, 2 controls). Of all treatments compared with usual care in efficacy outcomes, Mind-body exercise was associated with the best HRQOL (SMD, -12.12; 95% CI, -15.79 to -8.45). On the other characteristic symptom dimensions, based on moderate quality evidence, sensorimotor training was associated with minimal pain scores compared with usual care (SMD, -1.81; 95% CI, -2.81 to -0.82), whole body vibration therapy was most promising for improving sleep quality (SMD, -6.95; 95% CI, -10.03 to -3.87), pool-based aerobic exercise was most likely to ease anxiety (SMD, -4.83; 95% CI, -7.47 to -2.19), and whole body vibration was most likely to improve depression (SMD, -10.44; 95% CI, -22.00 to 1.12).

CONCLUSION

Mind-body exercise seems to be the most effective exercise to improve the overall HRQOL of patients with FMS. But at the same time, clinicians still need to develop individualized exercise plans for patients according to their symptoms and accessibility.

Gamification in Musculoskeletal Rehabilitation

PURPOSE OF REVIEW

This study is a narrative review aiming at evaluating the current literature of the last 5 years on gamification and musculoskeletal rehabilitation. The article search involved the following MeSH terms at PubMed: "gamification," "exergaming," and "rehabilitation." Original studies in English language were included.

RECENT FINDINGS

After careful analysis of the search results, 17 articles were included in this review. The use of games for rehabilitation was investigated in musculoskeletal rehabilitation conditions such as shoulder surgery, impingement syndrome, rheumatoid arthritis, osteoarthritis, low back pain, fibromyalgia, fracture, and ligament reconstruction. Results were similar or superior to conventional physical therapy or home-based exercises, with the additional benefit of improving motivation to the exercise program. Improvements in quality of life and perceived health status were also observed. The cost-effectiveness of this type of technology was also mentioned as an advantage of exergames in musculoskeletal rehabilitation. Studies involving gamification in musculoskeletal rehabilitation stress the potential of this resource in several aspects of physical fitness, health, and quality of life, also improving motivation and adherence to the exercise treatment.

Training-induced hypoalgesia and its potential underlying mechanisms

It is well-established that a single bout of exercise can reduce pain sensitivity (i.e., exercise-induced hypoalgesia) in healthy individuals. However, exercise-induced hypoalgesia is often impaired in individuals with chronic pain. This might suggest that repeated bouts of exercise (i.e., exercise training) are needed in order to induce a reduction in pain sensitivity (i.e., training-induced hypoalgesia) among individuals with chronic pain, given that a single bout of exercise seems to be insufficient to alter pain. However, the effect of repeated bouts of exercise on pain sensitivity and its underlying mechanisms remain poorly understood. Therefore, the purpose of this review was to provide an overview of the existing literature on training-induced hypoalgesia, as well as discuss potential mechanisms of training-induced hypoalgesia and offer considerations for future research. Existing literature suggests that training interventions may induce hypoalgesic adaptations potentially driven by central nervous system and immune system factors. However, the limited number of randomized controlled trials available, along with the lack of understanding of underlying mechanisms, provides a rationale for future research.

Benefits of Exergame Training for Female Patients With Fibromyalgia: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

OBJECTIVE

The objective of this systematic review and meta-analysis was to evaluate the effects of exergame training on female patients with fibromyalgia syndrome (FMS). Outcome measurements mainly include overall functioning, pain perception, quality of life, exercise capacity, health perception, kinesiophobia, and fatigue severity.

DATA SOURCES

Five electronic databases (PubMed, Web of Science, PsycInfo, Scopus, and Cochrane Library) were searched from inception until June 24, 2021. In addition to searches, review the reference lists of relevant papers by hand was also conducted. Cochrane Collaboration's tool for assessing risk of bias was used to evaluate the risk of bias in the included studies.

STUDY SELECTION

Articles were collected with the following study inclusion criteria: (1) randomized controlled trial (RCT) design; (2) participants were female patients with FMS aged older than 18 years; (3) participants in experimental groups received exergame training using any modality; and (4) outcome measures included overall functioning, quality of life, exercise capacity, health perception, kinesiophobia, and fatigue severity.

DATA EXTRACTION

The data were independently extracted by 2 researchers. The extracted data related to the document characteristics (first author, publication year, and country) participant characteristics (number and age of participants in the experimental and control groups), and interventions (intervention content, frequency, and duration, and measurement tools).

DATA SYNTHESIS

Nine RCTs including 466 female patients with FMS were included in the analysis. Exergame training had significant positive effects on overall functioning (standardized mean difference [SMD], -0.52; 95% confidence interval [CI], -0.77 to 0.27; P<.0001), pain perception (SMD, -0.49; 95% CI, -0.97 to -0.02; P=.04), quality of life (SMD, 0.77; 95% CI, 0.44-1.10; P<.00001), exercise capacity (SMD, 0.58; 95% CI, 0.32-0.84; P<.0001), health perception (SMD, 0.69; 95% CI, 0.38-1.01; P<.0001), and fatigue severity (SMD, -0.97; 95% CI, -1.55 to -0.38; P=.001). However, exergame training did not have significant effects on kinesiophobia (SMD, -1.13; 95% CI, -2.88 to 0.62; P=.21).

CONCLUSIONS

Exergame training has beneficial effects on the overall functioning, pain perception, quality of life, exercise capacity, health perception and fatigue severity of female patients with FMS. Exergame training is a potential non-drug therapy for the treatment of patients with FMS.

Effects of Gaming on Pain-Related Fear, Pain Catastrophizing, Anxiety, and Depression in Patients with Chronic Musculoskeletal Pain: A Systematic Review and Meta-Analysis

The aim was to systematically review the effects of gaming on pain-related fear, pain catastrophizing, anxiety, and depression in patients with chronic musculoskeletal pain. Databases (Medline, EMBASE, PsycInfo, CINAHL, Cochrane Central Register for Controlled Trials [CENTRAL], Web of Science, and SCOPUS) were searched from inception up to October 2021. Two reviewers independently selected randomized controlled trials that compared the effects of any gaming modality with other interventions or no treatment on pain-related fear, pain catastrophizing, anxiety, and depression. For data synthesis, Standardized Mean Differences (SMDs) and 95% confidence interval (CI) were calculated using a random-effects inverse variance model for meta-analysis according to the outcome of interest, comparison group, and follow-up period. The level of evidence was synthesized using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). Thirteen studies were included with a total sample of 680 patients. Gaming was superior to other treatments and no treatment on reducing pain-related fear (SMD: -1.23; 95% CI: -2.02 to -0.44) and anxiety (SMD: -0.55; 95% CI: -1.01 to -0.09), respectively. Gaming was not superior to other treatments on reducing pain catastrophizing, anxiety, and depression, and it was not superior to no treatment on reducing pain-related fear, pain catastrophizing, and depression. Those findings were based on very low or low-quality evidence. In a conclusion, gaming modalities may have positive effects on some mental health outcomes. However, there were conflicting results with low-quality evidence, which indicates that more high-quality randomized controlled trials are needed.

The Effectiveness of Serious Games in Alleviating Anxiety: Systematic Review and Meta-analysis

BACKGROUND

Anxiety is a mental disorder characterized by apprehension, tension, uneasiness, and other related behavioral disturbances. One of the nonpharmacological treatments used for reducing anxiety is serious games, which are games that have a purpose other than entertainment. The effectiveness of serious games in alleviating anxiety has been investigated by several systematic reviews; however, they were limited by design and methodological weaknesses.

OBJECTIVE

This study aims to assess the effectiveness of serious games in alleviating anxiety by summarizing the results of previous studies and providing an up-to-date review.

METHODS

We conducted a systematic review of randomized controlled trials (RCTs). The following seven databases were searched: MEDLINE, CINAHL, PsycINFO, ACM Digital Library, IEEE Xplore, Scopus, and Google Scholar. We also conducted backward and forward reference list checking for the included studies and relevant reviews. Two reviewers independently carried out the study selection, data extraction, risk of bias assessment, and quality of evidence appraisal. We used a narrative and statistical approach, as appropriate, to synthesize the results of the included studies.

RESULTS

Of the 935 citations retrieved, 33 studies were included in this review. Of these, 22 RCTs were eventually included in the meta-analysis. Very low-quality evidence from 9 RCTs and 5 RCTs showed no statistically significant effect of exergames (games entailing physical exercises) on anxiety levels when compared with conventional exercises (P=.70) and no intervention (P=.27), respectively. Although 6 RCTs demonstrated a statistically and clinically significant effect of computerized cognitive behavioral therapy games on anxiety levels when compared with no intervention (P=.01), the quality of the evidence reported was low. Similarly, low-quality evidence from 3 RCTs showed a statistically and clinically significant effect of biofeedback games on anxiety levels when compared with conventional video games (P=.03).

CONCLUSIONS

This review shows that exergames can be as effective as conventional exercises in alleviating anxiety; computerized cognitive behavioral therapy games and exergames can be more effective than no intervention, and biofeedback games can be more effective than conventional video games. However, our findings remain inconclusive, mainly because there was a high risk of bias in the individual studies included, the quality of meta-analyzed evidence was low, few studies were included in some meta-analyses, patients without anxiety were recruited in most studies, and purpose-shifted serious games were used in most studies. Therefore, serious games should be considered complementary to existing interventions. Researchers should use serious games that are designed specifically to alleviate depression, deliver other therapeutic modalities, and recruit a diverse population of patients with anxiety.

A Game-Based Approach to Lower Blood Pressure? Comparing Acute Hemodynamic Responses to Endurance Exercise and Exergaming: A Randomized Crossover Trial

The present randomized crossover study aimed to determine whether an exergaming session in an innovative, functional fitness game could be an effective exercise approach that elicits favorable blood pressure (BP) responses, such as a typical moderate endurance exercise (ET). Therefore, acute hemodynamic responses after a training session in the ExerCube and an ET on a treadmill were assessed and compared. Twenty-eight healthy recreational active participants (13 women; aged 24.8 ± 3.9 years) completed an exergaming session (EX) and an ET in a randomized and counterbalanced order. Before and throughout the 45 min after the training, the peripheral and central BP were measured. After the ET, there was a moderate decrease in both peripheral systolic (-1.8 mmHg; p = 0.14) and diastolic (-0.8 mmHg; p = 0.003), as well as central diastolic (-1.5 mmHg; p = 0.006) pressure compared to the resting value before the exercise. After the EX, there was a significant decrease in peripheral systolic (-6.3 mmHg; p < 0.001) and diastolic (-4.8 mmHg; p < 0.001), as well as central systolic (-5.8 mmHg; p < 0.001) and diastolic (-5.3 mmHg; p < 0.001) pressure compared to baseline. The interaction effects showed significant differences in peripheral and central systolic BP as well as in peripheral diastolic BP (p = 0.05). The EX seems to be an effective training approach that triggers relevant peripheral and central BP-responses, which are more pronounced than after a typical ET. Therefore, the ExerCube can be a time-efficient training tool to improve cardiovascular health.

Acute Effects of Heart Rate-Controlled Exergaming on Vascular Function in Young Adults

Objective: Acute and regular moderate-intensity endurance exercise (MIEE) is known to positively affect vascular function. The present study assessed if an exercise session in an innovative exergame called the ExerCube can induce similar vascular reactions as an MIEE session. Materials and Methods: Twenty-eight healthy recreationally active participants (13 females and 15 males; aged 24.8 ± 3.9 years; with body mass index 23.2 ± 2.3 kg/m²) completed an exergaming session (EGS) in the ExerCube (25 minutes) and an MIEE session on a treadmill (35 minutes, 65%-70% of maximal heart rate [HR]) in a randomized order. Both before and throughout the 45 minutes after the training sessions, pulse wave velocity (PWV), total peripheral resistance (TPR), stroke volume (SV), and HR were recorded. The study was approved by the Research Ethics Board of the Martin-Luther-Universität Halle-Wittenberg (Medical Faculty of the Martin-Luther-Universität 2019-177). Results: There were different hemodynamic responses to both types of exercises. PWV was significantly decreased 45 minutes after the EGS (P < 0.001). No significant changes were detected after MIEE (P = 0.109). TPR was significantly lower after both exercise sessions (P < 0.01). Only the EGS resulted in a significant decrease in SV 15 minutes after exercise (P < 0.001). The HR was significantly (P < 0.05) higher after both exercise sessions. After the EGS, the increase in HR was still significantly higher (P = 0.011) 45 minutes after the session. The interaction effects revealed significant differences in PWV (15 minutes, P = 0.035; 30 minutes, P = 0.004; and 45 minutes, P < 0.001), favoring the EGS. Conclusion: The EGS seems to induce a relevant exercise stimulus that can modulate vascular function. Therefore, this exergame may present an effective tool for prevention of cardiovascular diseases.

Virtual Reality-Based Therapy Reduces the Disabling Impact of Fibromyalgia Syndrome in Women: Systematic Review with Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Virtual reality-based therapy (VRBT) is a novel therapeutic approach to be used in women with fibromyalgia syndrome (FMS). The aim of our study is to assess the effect of VRBT to reduce the impact of FMS in outcomes such as pain, dynamic balance, aerobic capacity, fatigue, quality of life (QoL), anxiety and depression.

METHODS

Systematic review with meta-analysis was conducted from a bibliographic search in PubMed, Scopus, PEDro, Web of Science and CINAHL until April 2021 in accordance with PRISMA guidelines. We included randomized controlled trials (RCTs) that compare VRBT versus others to assess the mentioned outcomes in women with FMS. Effect size was calculated with standardized mean difference (SMD) and its 95% confidence interval (95% CI).

RESULTS

Eleven RCTs involving 535 women with FMS were included. Using the PEDro scale, the mean methodological quality of the included studies was moderate (6.63 ± 0.51). Our findings showed an effect of VRBT on the impact of FMS (SMD -0.62, 95% CI -0.93 to -0.31); pain (SMD -0.45, 95% CI -0.69 to -0.21); dynamic balance (SMD -0.76, 95% CI -1.12 to -0.39); aerobic capacity (SMD 0.32, 95% CI 0.004 to 0.63); fatigue (SMD -0.58, 95% CI -1.02 to -0.14); QoL (SMD 0.55, 95% CI 0.3 to 0.81); anxiety (SMD -0.47, 95% CI -0.91 to -0.03) and depression (SMD -0.46, 95% CI -0.76 to -0.16).

CONCLUSIONS

VRBT is an effective therapy that reduces the impact of FMS, pain, fatigue, anxiety and depression and increases dynamic balance, aerobic capacity and quality of life in women with FMS. In addition, VRBT in combination with CTBTE showed a large effect in reducing the impact of FMS and fatigue and increasing QoL in these women.

Analysis of the Muscular Activity, Peak Torque in the Lower Limbs, and Static Balance after Virtual Rehabilitation in Women with Fibromyalgia: A Randomized Controlled Study

Objective: To analyze the effect of the exergaming on muscular activity at rest and on maximum voluntary isometric contraction by electromyography (EMG) at peak torque, widespread pressure hyperalgesia identified using a tender point count, and static balance in fibromyalgia. Materials and Methods: Thirty-five women were divided into two groups: Wii™ (virtual rehabilitation, n = 16) and control (stretching exercises, n = 19), through simple randomization. The volunteers were evaluated by means of EMG, dynamometry by load cell, baropodometry, and algometry before interventions and reevaluated after the 10th and 20th sessions. The subjects participated fully in three 1-hour treatment sessions per week of 20 sessions. Results: The Wii group showed significant benefits for the peak torque of dorsiflexion movement after 20 sessions and for movement plantarflexion after 10 sessions. The control group showed bilateral improvement in muscular activity in the tibialis anterior muscle after 20 sessions. Both groups showed a significant decrease in tender point count, suggesting improved hyperalgesia after 10 sessions and 20 sessions. No significant improvement was found in static baropodometry in the two evaluated groups. Conclusion: Exergaming have the potential to increase the peak torque for dorsiflexion and plantarflexion movement in women with fibromyalgia. It also produces a decrease in tender point count equal to that with flexibility exercises and does not produce changes in the static balance.

The Effect of Virtual Reality Exercises on Pain, Functionality, Cardiopulmonary Capacity, and Quality of Life in Fibromyalgia Syndrome: A Randomized Controlled Study

Objective: To investigate the effect of motion-controlled videogames on pain, functionality, cardiopulmonary capacity, and quality of life in women with fibromyalgia. Materials and Methods: Forty women with fibromyalgia were randomized into virtual reality group (VRG) and conventional training group (CTG). The CTG performed aerobic exercise (cycling, 3 days per week, 20 minutes per day) and conventional exercises (muscle strengthening, balance, and flexibility, 3 days per week, 15 minutes per day) for 4 weeks. The VRG performed virtual reality exercise (volleyball, Microsoft Xbox Kinect^®, 3 days per week, 15 minutes per day) together with cycling exercise for 4 weeks. After the exercise program, both groups received the same home exercise program for 4 weeks. All patients were evaluated at baseline, fourth, and eighth weeks. Primary outcome measure was Fibromyalgia Impact Questionnaire. Visual Analogue Scale (VAS), Hospital Anxiety and Depression Scale, Fatigue Severity Scale (FSS), Symptom Severity Scale, EuroQol-Five Dimensions İndex Scale/Visual Analogue Scale (EQ-5D-index/VAS) and Six Minute Walk Test (6MWT) were used as secondary outcome measures. Results: Thirty-four patients (17 VRG, 17 CTG) were evaluated at the eighth week. After 4 weeks, all outcome measures improved significantly in both groups (P < 0.05). However, there was no statistically significant difference in all outcome measures between fourth and eighth weeks. Group and time interactions for 6MWT (P = 0.043), FSS (P = 0.026), EQ-5D-İndex Scale (P = 0.014), and EQ-5D-VAS (P = 0.049) were significant only for the VRG. In addition, median individual's satisfaction was significantly higher in the VRG (P < 0.001). Conclusion: Virtual reality exercises along with aerobic exercise increase cardiopulmonary capacity and quality of life in fibromyalgia syndrome. In addition, they increase patient satisfaction and may improve patient compliance to exercise.
