Efficacy of extracorporeal shockwave therapy, compared to corticosteroid injections, on pain, plantar fascia thickness and foot function in patients with plantar fasciitis: A systematic review and meta-analysis

OBJECTIVE

To compare the efficacy of extracorporeal shock waves versus corticosteroids injections on pain, thickness of plantar fascia and foot function in patients with plantar fasciitis. Secondarily, to assess the efficacy of radial and focused extracorporeal shock waves and the most appropriated intensity (high, medium or low).

DATA SOURCES

PubMed, SCOPUS, CINAHL and PEDro, until April 2024, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

REVIEW METHODS

Randomized controlled trials comparing the efficacy of extracorporeal shock waves versus corticosteroids injections on pain intensity and sensitivity, thickness of plantar fascia and foot function in patients with plantar fasciitis. Methodological quality and risk of bias were assessed using PEDro Scale and Cochrane Risk of Bias Tool. Pooled effect was calculated using the standardized mean difference (SMD) and its 95% confidence interval (95%CI).

RESULTS

Sixteen studies involving 1121 patients, showing a mean of 6 points in PEDro scale, were included. At three months, extracorporeal shock waves were better than corticosteroids injections in reducing pain (SMD -0.6; 95%CI -1.1 to -0.11) and thickness of the plantar fascia (SMD -0.4; 95%CI -0.8 to -0.01) and increasing foot function (SMD 0.27; 95%CI 0.12-0.44). At six months, extracorporeal shock waves are more effective in reducing pain (SMD -0.81; 95%CI -1.6 to -0.06) and increasing foot function (SMD 0.67; 95%CI 0.45-0.89). Local pain and slight erythema were the most frequent adverse events.

CONCLUSIONS

Extracorporeal shock waves are a safe therapy, presenting more efficacy than corticosteroids injections in improving pain, thickness of plantar fascia and foot function at mid-term.

Effectiveness of virtual reality-based therapy in pulmonary rehabilitation of chronic obstructive pulmonary disease. A systematic review with meta-analysis

BACKGROUND

In addition to conventional pulmonary rehabilitation (PR) programs for the treatment of chronic obstructive pulmonary disease (COPD), the use of virtual reality-based therapy (VRBT) has been proposed as an effective complementary tool to be included in PR programs for COPD.

OBJECTIVES

To analyze the effectiveness of VRBT on functional capacity, pulmonary function, and functional mobility in patients with COPD.

METHODS

A meta-analysis was carried out through a bibliographic search in PubMed (Medline), WOS, PEDro, CINAHL, CENTRAL, and Scopus since inception up to June 2023. The risk of bias was assessed using the PEDro scale, and the effect was determined using the standardized mean difference (SMD) and its 95 % confidence interval (95 % CI) in a random effects model.

RESULTS

Five RCTs, providing data from 344 participants with a mean age 65.7 ± 5.3 years old, were included. The mean methodological quality of the studies included was good (6.8 ± 1.6 points). The meta-analysis showed that VRBT was effective in increasing functional capacity, assessed with the 6 Min Walking Test, (SMD=0.4, 95 % CI 0.07 to 0.71, p = 0.017); pulmonary function, assessed with FEV1 (SMD=0.33, 95 %CI 0.01 to 0.65, p = 0.048); and functional mobility, assessed with the Get Up and Go Test (SMD=0.77, 95 % CI 0.5 to 1.1, p<0.001) in patients with COPD.

CONCLUSION

VRBT is suggested to be effective in increasing functional capacity, pulmonary function, and functional mobility in patients with COPD. Non-immersive VRBT is the most used modality of VRBT in PR.

Optokinetic stimulation for the treatment of vestibular and balance disorders: a systematic review with meta-analysis

OBJECTIVES

To analyse the effectiveness of optokinetic stimulation (OKS) for improving symptoms and function in patients with vestibular and balance disorders.

METHODS

PubMed (MEDLINE), SCOPUS, Web of Science (WOS), CINAHL Complete, and PEDro databases were searched to identify randomized controlled trials (RCTs) that included patients with vestibular and balance disorders and compared the effects of OKS versus other interventions or no intervention on subjective or objective functional outcomes. Data were analysed by the standardized mean difference (SMD) and its 95% confidence interval.

RESULTS

A total of 10 studies were selected including 468 patients, 177 of whom received OKS. There were no significant differences in scores on the Dizziness Handicap Inventory (DHI) (SMD = 0.02; 95% CI - 0.18 to 0.23; p = 0.83) or the visual analogue scale (VAS) for vertigo (SMD = 0.16; 95% CI - 1.25 to 1.58; p = 0.82). However, there were statistically significant differences in the timed up and go (TUG) test, with a large effect (SMD = - 1.13; 95% CI -2 to - 0.28; p = 0.009), and in the sensory organization test (SOT), with a medium effect (SMD = - 0.7; 95% CI - 1.21 to - 0.19; p = 0.007). Subgroup analysis showed significant effects of OKS on VAS (p = 0.017), TUG (p = 0.009) and SOT (p = 0.001) only in patients with balance disorders without vestibular disease (p > 0.05).

CONCLUSIONS

OKS may improve dizziness intensity measured with VAS or dynamic balance measured whit TUG and SOT in patients with balance disorders not due to vestibular disease. The quality of the evidence was low or very low due to the small number of included studies.

Idiopathic scoliosis in subjects with eye diseases: A systematic review with meta-analysis

Our aim was to find the best evidence on the prevalence of idiopathic scoliosis (IS) in subjects with eye diseases (EDs) and to determine the most common visual alterations that are present. Following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), a bibliographic search up to June 2023 in the PubMed, PsycINFO, SCOPUS, and CINAHL Complete databases was performed. Observational studies were selected and the results were analyzed with prevalence odds ratio (OR). A total of six studies, including 18,396 subjects, were selected. The group of subjects with EDs was made up of 6048 individuals, of whom 655 (10.83%) had IS. The group of subjects without EDs was made up of 12,348 individuals of whom 444 (3.60%) presented with IS with an OR = 2.91, CI (95%) = [1.75, 4.83]. Blindness was assessed in a single study with an OR = 7.83, CI (95%) = [1.66, 36.90]; all three studies in the refractive error subgroup yielded an OR = 2.24, CI (95%) = [1.10, 4.58]; and the two studies that included subjects with strabismus showed an OR = 3.09, CI (95%) = [1.38, 7.00]. EDs were associated with an almost three times greater odds of having IS. We recommend the inclusion of vision testing in children with IS.

Validity and reliability of the Niigata PPPD Questionnaire in a Western population

PURPOSE

To analyze the psychometric properties of the Niigata Questionnaire (NPQ) for use in a European population with persistent postural-perceptual dizziness (PPPD).

METHODS

Observational study included 140 patients with different vestibular conditions. Construct validity, internal consistency and concurrent validity were analyzed. Intra-class correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) were calculated. Receiver operating characteristic (ROC) curve was used to test diagnostic values.

RESULTS

Of the 140 patients, 47 had a diagnosis of PPPD. Factorial analysis showed a single-factor structure and concurrent validity analysis showed strong correlations with other instruments. Cronbach alpha coefficients of 0.938 for the total score, 0.869 for the standing and gait subscale, 0.803 for the subscale of movements and 0.852 for the visual stimulation subscale were obtained. The reproducibility was substantial except for the standing subscale, which could be considered moderate. For the standing, movement and visual stimulation subscales and for the total score, the SEM was 3.27, 2.41, 2.50 and 6.63, respectively, and the MDC was 6.40, 4.72, 4.91 and 12.99, respectively. The NPQ total score showed an area under the curve (AUC) of 0.661, a sensitivity of 72.34 and a specificity of 55.91 for discriminating between PPPD and other vestibular disorders.

CONCLUSIONS

The NPQ is feasible for use in a Western population and presents a uni-factorial structure, high internal consistency and strong correlation with other instruments. The reliability can be considered substantial. The NPQ has low accuracy in discriminating between subjects with or without PPPD.

Relationship between stomatognathic alterations and idiopathic scoliosis: a systematic review with meta-analysis of observational studies

Purpose

The objective of this systematic review was to assess a possible relationship between stomatognathic alterations and idiopathic scoliosis (IS).

Design

This study is a systematic review with meta-analysis of observational studies.

Methods

The protocol of this systematic review with meta-analysis was registered in PROSPERO (CRD42022370593). A bibliographic search was carried out in the Pubmed (MEDLINE), Scopus, Web of Science and CINAHL databases using the MeSH terms 'Scoliosis' and 'Stomatognathic Disease'. The odds ratio (OR) of prevalence and standardized mean difference (SMD) were used to synthesize the results.

Results

Of 1592 studies located, 14 studies were selected with 3018 subjects (age: 13.9 years). IS was related to Angle's class II (OR = 2.052, 95% CI = 1.236-3.406) and crossbite (OR = 2.234, 95% CI = 1.639-3.045). Patients with malocclusion showed a higher prevalence of IS than controls (OR = 4.633, 95% CI = 1.467-14.628), and subjects with IS showed high overjet (SMD = 0.405, 95% CI = 0.149-0.661) and greater dysfunction due to temporomandibular disorders (SMD = 1.153, 95% CI = 0.780-1.527).

Conclusion

Compared with healthy controls, subjects with IS have twice the risk of suffering from occlusion disorders, present greater temporomandibular dysfunction and have a greater overjet in the incisors. Moreover, subjects with malocclusion have an IS prevalence up to four times higher. The systematic orofacial examination of patients with IS should be recommended.

Transcultural Adaptation and Psychometric Validation of the Spanish Version of the Pain Attitudes and Beliefs Scale for Physiotherapists

Low back pain (LBP) is one of the main musculoskeletal pain conditions, and it affects 23-28% of the global population. Strong evidence supports the absence of a direct relationship between the intensity of pain and tissue damage, with psychosocial factors also playing a crucial role. In this context, the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) is a useful tool for evaluating physiotherapists' treatment orientations and beliefs regarding the management of low back pain (LBP). It helps identify practitioners who may benefit from additional education in modern pain neuroscience. However, there is not a Spanish validation of this scale for physiotherapists. Thus, the aims of this study were to translate and culturally adapt the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT) into Spanish and to evaluate its psychometric properties. This validation study used three convenience samples of physiotherapists (PTs) (n = 22 for the pilot study, n = 529 for the validity study and n = 53 for assessing the instrument's responsiveness). The process of translating and adapting the PABS-PT into Spanish followed international guidelines and produced a satisfactory pre-final version of the questionnaire. Factor analysis confirmed the two-factor structure of the original version, with the biomedical (BM) factor explaining 39.4% of the variance and the biopsychosocial (BPS) factor explaining 13.8% of the variance. Cronbach's alpha values were excellent for the BM factor (0.86) and good for the BPS factor (0.77), indicating good internal consistency. Test-retest reliability was excellent for both factors, with intraclass correlation coefficients (ICCs) of 0.84 for BM and 0.82 for BPS. The standard error of measurement (SEM) was acceptable for both factors (3.9 points for BM and 2.4 points for BPS). Concurrent validity was moderate and in the expected direction and had significant correlations with the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) and Revised Neurophysiology Pain Questionnaire (R-NPQ). Sensitivity to change was demonstrated by significant improvements in both factors after an educational intervention, with medium-to-large effect sizes. The PABS-PT also showed good discriminative ability, as it was able to distinguish between physiotherapists with and without pain education. Cut-off values for the BM and BPS factors were determined. In conclusion, the translated and adapted Spanish version of the PABS-PT demonstrated good psychometric properties and can be reliably used to assess the attitudes and beliefs of Spanish-speaking physiotherapists regarding LBP. The questionnaire is recommended for use in clinical and educational research in the Spanish language context.

Effectiveness of Vestibular Rehabilitation in Improving Health Status and Balance in Patients with Fibromyalgia Syndrome: A Single-Blind Randomized Controlled Trial

BACKGROUND

Fibromyalgia Syndrome (FMS) is a highly prevalent health problem whose main symptom is widespread pain, although it presents as other manifestations, such as loss of balance, that seem to mainly affect visuo-vestibular information.

OBJECTIVE

to compare the effects of a Vestibular Rehabilitation (VR) program versus those of a Conventional Physical Exercise (CPE) program on the health status of patients with FMS.

METHODS

A single-blind randomized controlled trial was performed. Patients with FMS were randomly assigned to VR or CPE programs. The protocols were performed in 40 min group sessions, twice weekly, for 16 sessions. Perceived health status, static and dynamic balance, verticality perception, confidence in balance, sensitization and kinesiophobia were measured at baseline, post-treatment and at the three-month follow-up and analyzed using an intention-to-treat approach.

RESULTS

Forty-eight subjects were randomly assigned, of whom thirty-five completed the planned VR (n = 19) or CPE (n = 16) program. At the three-month follow-up, there were differences in physical health status measured with the SF-12 (mean = -4.36, SE = 1.88, p = 0.027), balance during walking (mean = 1.90, SE = 0.57, p = 0.002), the perception of verticality in degrees (mean = 3.61, SE = 1.51, p = 0.024) and the anteroposterior position of the center of pressure (mean = -7.88, SE = 2.80, p = 0.009), as well as a decrease in the number of falls (mean = 0.98, SE = 0.44, p = 0.033), favoring the VR group.

CONCLUSIONS

Vestibular Rehabilitation can be as beneficial as conventional exercise in improving the state of health in patients with Fibromyalgia Syndrome, providing additional improvements in physical health status, body balance, the perception of verticality and the number of falls.

Virtual reality-based therapy improves balance and reduces fear of falling in patients with multiple sclerosis. a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

This study aims to conduct a meta-analysis to assess the effect of virtual reality-based therapy (VRBT) on balance dimensions and fear of falling in patients with multiple sclerosis (PwMS). Secondarily, to determine the most recommendable dose of VRBT to improve balance.

METHODS

PubMed Medline, Web of Science, Scopus, CINAHL and PEDro were screened, without publication date restrictions, until September 30th, 2021. Randomized controlled trials (RCTs) comparing the effectiveness of VRBT against other interventions in PwMS were included. Functional and dynamic balance, confidence of balance, postural control in posturography, fear of falling and gait speed were the variables assessed. A meta-analysis was performed by pooling the Cohen's standardized mean difference (SMD) with 95% confidence interval (95% CI) using Comprehensive Meta-Analysis 3.0.

RESULTS

Nineteen RCTs, reporting 858 PwMS, were included. Our findings reported that VRBT is effective in improving functional balance (SMD = 0.8; 95%CI 0.47 to 1.14; p < 0.001); dynamic balance (SMD = - 0.3; 95%CI - 0.48 to - 0.11; p = 0.002); postural control with posturography (SMD = - 0.54; 95%CI - 0.99 to - 0.1; p = 0.017); confidence of balance (SMD = 0.43; 95%CI 0.15 to 0.71; p = 0.003); and in reducing fear of falling (SMD = - 1.04; 95%CI - 2 to - 0.07; p = 0.035); but not on gait speed (SMD = - 0.11; 95%CI: - 0.35 to 0.14; p = 0.4). Besides, the most adequate dose of VRBT to achieve the greatest improvement in functional balance was at least 40 sessions, five sessions per week and 40-45 min per sessions; and for dynamic balance, it would be between 8 and 19 weeks, twice a week and 20-30 min per session.

CONCLUSION

VRBT may have a short-term beneficial role in improving balance and reducing fear of falling in PwMS.

Exercise therapy improves pain and mouth opening in temporomandibular disorders: A systematic review with meta-analysis

OBJECTIVE

To analyse the effectiveness of exercise therapy in improving pain and active or passive maximum mouth opening in patients with temporomandibular disorders.

DATA SOURCES

PubMed Medline, Web of Science, Scopus, CINAHL Complete and Physiotherapy Evidence Database, until April 2022, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

REVIEW METHODS

We included randomized controlled trials evaluating the effect of exercise therapy on pain and on active and passive maximum mouth opening in patients with temporomandibular disorders. Effect size was calculated using Cohen's standardized mean difference (SMD) and their 95% confidence interval (95% CI) in a random-effects model.

RESULTS

A total of 16 studies with 812 participants were included. Exercise therapy is effective in reducing pain (SMD: -0.58; 95% CI: -1.01 to -0.12) and increasing the pain pressure threshold (SMD: 0.45; 95% CI: 0.14-0.76), active and passive maximum mouth opening (SMD: 0.43; 95% CI: 0.14-0.71 and SMD: 0.4; 95% CI: 0.06-0.75, respectively). Subgroup analyses showed more effect of exercise therapy more splints versus splints on pain (SMD: -0.5; 95% CI: -0.73 to -0.26), active and passive maximum mouth opening (SMD: 1.14; 95% CI: 0.22-2.07 and SMD: 0.56; 95% CI: 0.06-1.06, respectively). On pain pressure threshold, exercise therapy was better than physiotherapy approach (manual therapy and electrotherapy) (SMD: 0.48; 95% CI: 0.09-0.87).

CONCLUSIONS

Therapeutic exercise is an effective therapy to reduce pain and increase pain pressure threshold and active and passive maximum mouth opening in patients with temporomandibular disorders.

Psychometric Properties of the Short Version of the Activities-Specific Balance Confidence Scale in Vestibular Patients

BACKGROUND

This study aimed to analyze the psychometric properties of the Activities-specific Balance Confidence Scale Short Version (ABC-6) in vestibular patients.

METHODS

The sample consisted of 87 subjects aged over 18 years with vestibular pathology. Construct validity, internal consistency, test-retest reliability, concurrent validity, and capacity to discriminate between subjects with or without risk of falling as measured with the ABC-16 standard version were analyzed.

RESULTS

The ABC-6 showed a unifactorial structure. Cronbach's alpha was 0.873. The reliability was moderate for each of the items and substantial for the total score (intraclass correlation coefficient = 0.778). The standard error of measurement was 10.24, with a minimum detectable change of 20.07. The ABC-6 version showed a strong correlation with physical and functional measures, moderate correlation with emotional measures, and poor correlation with the Physical Component Summary of SF-12 and retrospective 12-month falls. A cutoff point ≤55 showed a sensitivity = 94.44% and a specificity = 92.75% in differentiating between patients with or without risk of falling measured with the ABC-16 standard version, with an area under the curve = 0.975.

CONCLUSIONS

The ABC-6 showed acceptable psychometric properties for measuring balance confidence and risk of falling in vestibular patients.

Optimal dose and type of exercise to reduce pain, anxiety and increase quality of life in patients with fibromyalgia. A systematic review with meta-analysis

The aim of our meta-analysis was to compile the available evidence to evaluate the effect of physical exercise-based therapy (PEBT) on pain, impact of the disease, quality of life (QoL) and anxiety in patients with fibromyalgia syndrome (FMS), to determine the effect of different modes of physical exercise-based therapy, and the most effective dose of physical exercise-based therapy for improving each outcome. A systematic review and meta-analysis was carried out. The PubMed (MEDLINE), SCOPUS, Web of Science, CINAHL Complete and Physiotherapy Evidence Database (PEDro) databases were searched up to November 2022. Randomized controlled trials (RCTs) comparing the effects of physical exercise-based therapy and other treatments on pain, the impact of the disease, QoL and/or anxiety in patients with FMS were included. The standardized mean difference (SMD) and a 95% CI were estimated for all the outcome measures using random effect models. Three reviewers independently extracted data and assessed the risk of bias using the PEDro scale. Sixty-eight RCTs involving 5,474 participants were included. Selection, detection and performance biases were the most identified. In comparison to other therapies, at immediate assessment, physical exercise-based therapy was effective at improving pain [SMD-0.62 (95%CI, -0.78 to -0.46)], the impact of the disease [SMD-0.52 (95%CI, -0.67 to -0.36)], the physical [SMD 0.51 (95%CI, 0.33 to 0.69)] and mental dimensions of QoL [SMD 0.48 (95%CI, 0.29 to 0.67)], and the anxiety [SMD-0.36 (95%CI, -0.49 to -0.25)]. The most effective dose of physical exercise-based therapy for reducing pain was 21-40 sessions [SMD-0.83 (95%CI, 1.1--0.56)], 3 sessions/week [SMD-0.82 (95%CI, -1.2--0.48)] and 61-90 min per session [SMD-1.08 (95%CI, -1.55--0.62)]. The effect of PEBT on pain reduction was maintained up to 12 weeks [SMD-0.74 (95%CI, -1.03--0.45)]. Among patients with FMS, PEBT (including circuit-based exercises or exercise movement techniques) is effective at reducing pain, the impact of the disease and anxiety as well as increasing QoL.

Corrective exercise-based therapy for adolescent idiopathic scoliosis: Systematic review and meta-analysis

OBJECTIVE

to analyze the efficacy of Corrective exercise-based therapy in the improvement of deformity and quality of life in adolescent idiopathic scoliosis.

DATA SOURCES

PubMed Medline, Scopus, Web of Science (WOS), Physiotherapy Evidence Database, CINAHL Complete and SciELO, until June 2021.

REVIEW METHODS

Randomized controlled trials was selected, including participants diagnosed with adolescent idiopathic scoliosis, in which the experimental group received Corrective exercise-based therapy. Two authors independently searched the scientific literature in the data sources, extracted the data and assessed the risk of bias. A pairwise meta-analysis using the random-effects model was performed.

RESULTS

Eight randomized controlled trials providing data from 279 adolescent idiopathic scoliosis patients were included. Seven randomized controlled trials including 236 patients showed moderate-quality evidence for a medium effect (SMD = -0.52, 95% CI -0.96 to -0.1), favoring corrective exercise-based therapy for spinal deformity reduction. Corrective exercise-based therapy was better than no intervention (SMD = -0.59, 95% CI -1.18 to -0.01) but similar to other intervention (SMD = -0.2, 95% CI -0.67 to 0.27), and a medium effect was found (SMD = -0.51, 95% CI -0.89 to -0.13) when corrective exercise-based therapy was used with other therapies. Four studies including 151 patients showed low-quality evidence of a large effect of Corrective exercise-based therapy on Scoliosis Research Society measurement (SRS-22) total score improvement (SMD = 1.16, 95% CI 0.36 to 1.95).

CONCLUSION

In mild and moderate adolescent idiopathic scoliosis patients, corrective exercise-based therapy could be used to reduce spinal deformity and to improve quality of life as isolated treatment or as coadjuvant treatment combined with other therapeutic resources.

The Short Form of the Fonseca Anamnestic Index for the Screening of Temporomandibular Disorders: Validity and Reliability in a Spanish-Speaking Population

The Short Form of the Fonseca Anamnestic Index (SFAI) is a simple and quick questionnaire used for screening temporomandibular disorders (TMDs). The present study aimed to validate the Spanish version of the SFAI in patients with TMDs. The study sample comprised 112 subjects (50 TMDs and 52 controls). Test–retest reliability, factorial validity, internal consistency, concurrent validity, and the SFAI’s ability to discriminate between TMDs subjects and healthy controls were analyzed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD protocol) as the reference. Factor analysis showed a single factor that explained 63% of the total variance. Cronbach’s alpha was 0.849. The reliability of the items measured with the Kappa index showed values from 0.767 to 0.888. Test–retest reliability was substantial (intraclass correlation coefficient = 0.837). The total SFAI score showed a significant correlation with orofacial pain, vertigo, and neck disability measurements. For a cut-off point of >10 points, the SFAI showed a sensitivity of 78% and specificity of 78.85% at differentiating between TMDs patients and healthy subjects, with an area under the curve (AUC) of 0.852. The Spanish version of the SFAI is a valid and reliable instrument for diagnosing people with TMDs and shows generally good psychometric properties.

Spanish Questionnaires for the Assessment of Pelvic Floor Dysfunctions in Women: A Systematic Review of the Structural Characteristics and Psychometric Properties

BACKGROUND

Pelvic floor dysfunctions affect a third of the adult female population, including a large number of clinical conditions, which can be evaluated through validated questionnaires that inform us of the status and perception of women both objectively and subjectively. The main objective of this study was to review and explain the topics of the validated questionnaires in Spanish on pelvic floor dysfunctions and to review their psychometric properties.

METHODS

A systematic review was carried out in the PUBMED and WOS databases. The keywords used were in PUBMED: (((((((("Fecal Incontinence" [Mesh]) OR "Urinary Incontinence" [Mesh]) OR "Pelvic Organ Prolapse" [Mesh]) OR "Pelvic Floor Disorders" [Mesh]) OR "Sexual Dysfunction, Physiological" [Mesh]) OR "Pelvic Girdle Pain" [Mesh]) OR "sexual function" [Title/Abstract]) OR "Prolapse" [Title/Abstract]) AND "Surveys and Questionnaires" [Mesh] AND "Validation" [Title/Abstract] combined with the Boolean operators "AND"/"OR". In contrast, in WOS, a segregated search was carried out with each of the terms of pelvic floor dysfunction together with "Validation" and "Surveys and Questionnaires". All articles published up to 19 November 2021 were considered. Methodological quality was assessed with the COSMIN scale.

RESULTS

A total of 687 articles were identified, of which 13 were included. The evaluated questionnaires and the structural characteristics and psychometric properties of each of them were collected.

CONCLUSION

The Spanish versions of the questionnaires show good basic structural and psychometric characteristics for the evaluation of patients with pelvic floor dysfunctions and that they resemble other versions of the same questionnaire published in other languages.

The Type of Conservative Management Could Be Related to the Strength of the Inspiratory Muscles of Adolescents with Idiopathic Scoliosis—A Case Series

Adolescent idiopathic scoliosis (AIS) is a lateral curvature of the spine with a Cobb angle of at least 10° with an unknown etiology. It is recognized that AIS may affect respiratory function. This study aims to describe and compare respiratory function in a case series of patients with scoliosis who underwent different types of therapeutic management: no intervention, orthotic brace, and global postural reeducation (GPR). Fifteen AIS patients were included in this study (seven no intervention, four orthotic brace and four GPR). Lung function and inspiratory muscle strength were measured and analyzed, as well as sociodemographic, clinical, and anthropometric variables. Significant correlations were observed between height (cm) and maximum inspiratory pressure (MIP) reference (cmH2O) and forced vital capacity (FVC) (liters) (r = 0.650 and r = 0.673, respectively; p < 0.01); weight (Kg) and MIP reference (cmH2O) (r = 0.727; p < 0.01); and Main curve degrees (Cobb angle) and FVC% (r = −0.648; p < 0.01). The AIS cases that underwent GPR treatment presented a greater MIP (% predictive) compared to the no intervention and brace cases (201.1% versus 126.1% and 78.4%, respectively; p < 0.05). The results of this case series show a possible relation whereby patients undergoing treatment with the GPR method have greater inspiratory muscle strength compared to the no intervention and brace cases. Studies with larger samples and prospective designs must be performed to corroborate these results.

Nintendo Wii Balance Board therapy for postural control in children with cerebral palsy: a systematic review and meta-analysis

AIM

To analyse the efficacy of Nintendo Wii therapy (NWT) on functional balance in children with cerebral palsy (CP).

METHOD

A systematic review with meta-analysis (PROSPERO identification number CRD42020169510) was performed using randomized controlled trials (RCTs) that examined the effect of NWT on functional, dynamic, and static balance in children with CP, assessed with the Pediatric Balance Scale, the Timed Get Up and Go Test, and the One Leg Stance Test respectively. The pooled effect was calculated using the Cohen's standardized mean difference (SMD).

RESULTS

Eleven RCTs with 270 children (when sex was reported: 43% females, 57% males) with CP (mean age [SD] 10y 1mo [1y 1mo], range 5-16y) were included. On functional balance, we found very low-quality evidence with a large effect of NWT compared with no intervention (SMD 0.95, 95% confidence interval [CI] 0.02-1.89) and moderate-quality evidence for using NWT plus conventional physical therapy (CPT) versus CPT (SMD 0.78, 95% CI 0.20-1.35) in sessions of approximately 30 minutes (SMD 0.86, 95% CI 0.20-1.52) and interventions lasting longer than 3 weeks (SMD 1.03, 95% CI 0.58-1.47). For dynamic balance, very low-quality evidence for a medium effect for using NWT plus CPT versus CPT (SMD 0.70, 95% CI 0.12-1.29) was found.

INTERPRETATION

NWT can be considered an effective treatment for improving functional and dynamic balance in children with CP, especially when combined with CPT in 30-minute sessions with interventions lasting longer than 3 weeks. What this paper adds Moderate-quality evidence with a large effect of Nintendo Wii therapy (NWT) on functional balance, compared with conventional physical therapy (CPT). Moderate-quality evidence with medium effect of NWT plus CPT on functional and dynamic balance, compared with CPT. Appropriate NWT sessions should be equal to or slightly less than 30 minutes. NWT interventions must be longer than 3 weeks.

Psychometric Evaluation of the Krogh-Poulsen Test for the Diagnosis of the Temporomandibular Disorders

The Krogh-Poulsen Test is a classic instrument to measure dysfunction of the stomatognathic system whose psychometric properties are unknown. This study aimed to evaluate the psychometric properties of the Krogh-Poulsen Test for the diagnosis of temporomandibular disorders (TMDs). A cross-sectional study was designed, including 119 patients (63 patients with TMD and 56 healthy controls). Factorial validity, inter-rater reliability, error of measurement, diagnostic validity of the Krogh-Poulsen Test, and concurrent validity were analyzed. The Krogh-Poulsen Test showed a three-factor structure. The inter-rater agreement could be considered very good with a kappa index of 0.87 (95% CI 0.83-0.90) and Standard Error of Measurement of 0.79. Correlations were strong with other orofacial instruments, moderate with instruments measuring TMD-related disorders such as neck pain, headache, or dizziness, and poor with generic quality of life instruments. The Area Under the Curve ROC was 0.928 showing, for a cut-off point >1, a sensitivity of 90.48 (95% CI 80.4-96.4) and a specificity of 85.71 (95% CI 73.8-93.6) for the diagnosis of TMD disorders. The Krogh-Poulsen Test showed a three-factor structure, very good inter-rater reliability, a strong correlation with other orofacial instruments, and an excellent capacity to discriminate between patients with or without TMD.

Leap Motion Controller Video Game-Based Therapy for Upper Extremity Motor Recovery in Patients with Central Nervous System Diseases. A Systematic Review with Meta-Analysis

Leap Motion Controller (LMC) is a virtual reality device that can be used in the rehabilitation of central nervous system disease (CNSD) motor impairments. This review aimed to evaluate the effect of video game-based therapy with LMC on the recovery of upper extremity (UE) motor function in patients with CNSD. A systematic review with meta-analysis was performed in PubMed Medline, Web of Science, Scopus, CINAHL, and PEDro. We included five randomized controlled trials (RCTs) of patients with CNSD in which LMC was used as experimental therapy compared to conventional therapy (CT) to restore UE motor function. Pooled effects were estimated with Cohen's standardized mean difference (SMD) and its 95% confidence interval (95% CI). At first, in patients with stroke, LMC showed low-quality evidence of a large effect on UE mobility (SMD = 0.96; 95% CI = 0.47, 1.45). In combination with CT, LMC showed very low-quality evidence of a large effect on UE mobility (SMD = 1.34; 95% CI = 0.49, 2.19) and the UE mobility-oriented task (SMD = 1.26; 95% CI = 0.42, 2.10). Second, in patients with non-acute CNSD (cerebral palsy, multiple sclerosis, and Parkinson's disease), LMC showed low-quality evidence of a medium effect on grip strength (GS) (SMD = 0.47; 95% CI = 0.03, 0.90) and on gross motor dexterity (GMD) (SMD = 0.73; 95% CI = 0.28, 1.17) in the most affected UE. In combination with CT, LMC showed very low-quality evidence of a high effect in the most affected UE on GMD (SMD = 0.80; 95% CI = 0.06, 1.15) and fine motor dexterity (FMD) (SMD = 0.82; 95% CI = 0.07, 1.57). In stroke, LMC improved UE mobility and UE mobility-oriented tasks, and in non-acute CNSD, LMC improved the GS and GMD of the most affected UE and FMD when it was used with CT.

Joint Assessment of Equilibrium and Neuromotor Function: A Validation Study in Patients with Fibromyalgia

OBJECTIVE

To develop and validate a tool for evaluating balance and neuromotor function in patients with fibromyalgia (FMS).

METHODS

Brainstorming, the nominal group technique, and pilot-testing were used to select a battery of 20 functional balance tests that were included in a screening tool. A total of 108 subjects (62 with fibromyalgia syndrome, 22 aged over 65 years, and 24 healthy subjects) participated in this validation study. Factor validity, internal consistency, the ability to discriminate between patients and healthy subjects, and concurrent validity with the Fibromyalgia Impact Questionnaire (FIQ), the Central Sensitization Inventory (CSI), the 12-Item Short-Form Health Survey (SF-12), and other tools for measuring balance, such as the Dizziness Handicap Inventory (DHI), the Activities-Specific Balance Confidence Scale (ABC-16), the Falls Efficacy Scale-International (FES-I), and posturographic parameters, were evaluated.

RESULTS

The factorial analysis extracted four factors that explained 70% of the variance. The Alpha Cronbach value was 0.928. Concurrent validity of the screening tool with respect to other tools was high, and the receiver operating characteristic (ROC) curve analysis showed an AUC value of 0.932 for discriminating between healthy and FMS subjects. Severe balance disorder related to head movements in FMS patients was found.

CONCLUSION

The 20-item JAEN (Joint Assessment of Equilibrium and Neuro-motor Function) screening tool is a valid and reliable tool for assessing balance in patients with FMS.

New Mobile Device to Measure Verticality Perception: Results in Young Subjects with Headaches

The subjective visual vertical (SVV) test has been frequently used to measure vestibular contribution to the perception of verticality. Recently, mobile devices have been used to efficiently perform this measurement. The aim of this study was to analyze the perception of verticality in subjects with migraines and headaches. A cross-sectional study was conducted that included 28 patients with migraine, 74 with tension-type headache (TTH), and 93 healthy subjects. The SVV test was used through a new virtual reality system. The mean absolute error (MAE) of degrees deviation was also measured to qualify subjects as positive when it was greater than 2.5°. No differences in the prevalence of misperception in verticality was found among healthy subjects (31.18%), migraineurs (21.43%), or those with TTH (33.78%) (p = 0.480). The MAE was not significantly different between the three groups (migraine = 1.36°, TTH = 1.61°, and healthy = 1.68°) (F = 1.097, p = 0.336, and η2 = 0.011). The perception of verticality could not be explained by any variable usually related to headaches. No significant differences exist in the vestibular contribution to the perception of verticality between patients with headaches and healthy subjects. New tests measuring visual and somatosensory contribution should be used to analyze the link between the perception of verticality and headaches.

Misperception of Visual Verticality in Patients with Primary Headache Disorders: A Systematic Review with Meta-Analysis

Migraine and tension-type headache (TTH) are the two most prevalent primary headache disorders (PHDs) that may involve visual and vestibular impairments, neck pain, and postural unsteadiness. The perception of visual verticality (VV) has been studied in patients diagnosed with PHD to assess balance disorders showing varying findings. Our study aimed to assess the VV perception in patients diagnosed with PHD in comparison to healthy controls. A systematic review with meta-analysis was carried out in PubMed MEDLINE, Scopus, WOS, CINAHL, and SciELO. The Cohen standardized mean difference (SMD) was used to estimate the differences between exposed and healthy controls. Seven studies with 816 participants were included. The quality of included studies, according to the Newcastle–Ottawa Scale (NOS), was moderate (mean score of 5.2). Patients diagnosed with PHD showed a moderate misperception of VV as assessed with the subjective visual vertical (SVV) test (SMD = 0.530; 95% CI = 0.225, 0.836; p < 0.001). Specifically, a misperception of the SVV was found in patients with migraine (SMD = 0.369; 95% CI = 0.1, 0.638; p = 0.007) and with TTH (SMD = 1.122; 95% CI = 0.540, 1.704; p < 0.001). This review shows a misperception of VV in patients with migraine and TTH when assessed with the SVV test, being higher in patients with TTH, although the THH sample size was low.

Misperception of Visual Vertical in Peripheral Vestibular Disorders. A Systematic Review With Meta-Analysis

OBJECTIVE

The main aim was to assess the misperception of visual verticality (VV) in patients with peripheral vestibular disorders (PVD) in comparison with healthy controls. As secondary objectives, we checked if vestibular, visual, and somatosensory postural pathways can be affected in patients with PVD as well as the characteristics of PVD that could influence on the VV perception.

METHODS

A systematic review with meta-analysis was carried out. The bibliographic search was performed in January, 2020 in PubMed, Scopus, Web of Science (WOS), CINAHL, SciELO. Two reviewers selected the studies that met the inclusion criteria, extracted data, and assessed the methodological quality using the Newcastle-Ottawa Scale (NOS). The VV perception was assessed in two meta-analysis according the used test: The Subjective Visual Vertical test (SVV) or the Rod and Frame Test (RFT) in comparison with healthy subjects. The Standardized Mean Difference (SMD) and its 95% Confidence Interval (95% CI) was used to estimate the pooled effect. Publication bias was assessed using the Egger's test and Trim and Fill Method.

RESULTS

Thirty-four studies were included reporting 3,524 participants. PVD patients showed a misperception of the VV with SVV (SMD = 1.510; 95%CI: 1.190-1.830) and the RFT (SMD = 0.816; 95% CI: 0.234-1.398) respect healthy controls. A subgroup of patients in the acute phase (SMD = 2.5; 95%CI: 2.022-2.978) and who underwent a vestibular surgery (SMD = 2.241; 95%CI: 1.471-3.011) had the greater misperception of VV.

CONCLUSION

Patients with PVD show an alteration in the perception of VV, being greater in the acute phase and after a vestibular surgery. Laryngoscope, 131:1110-1121, 2021.

Neck Pain- and Unsteadiness-Inducing Activities and their Relationship to the Presence, Intensity, Frequency, and Disability of Headaches

(1) Background: Headache is a significant public health problem. Despite the association between headache and neck pain, little is known about the relationships among specific activities that generate neck pain and headache. The aim of this study was to identify the specific activities that result in neck pain and unsteadiness, and determine how they are linked to headache in university students. (2) Methods: One hundred and six patients with physician-diagnosed headache and 92 healthy university students completed surveys assessing demographics; the presence, frequency, intensity, and disability of headaches; and activities generating neck pain and unsteadiness. (3) Results: The presence of headache was related to female gender (p = 0.001), neck pain when reading or watching television (p = 0.024), and unsteadiness when moving the head (p = 0.005). Headache-related disability was associated with intensity of neck pain (p < 0.001), neck pain when reading or watching television (p = 0.033), and stumbling (p < 0.001). Headache frequency was related to smoking (p = 0.004), the duration of neck pain-associated symptoms (p = 0.047), and neck pain when driving (p = 0.039). Intensity of headache was associated with female gender (p = 0.002), smoking (p = 0.013), and neck pain-related sleep alterations (p = 0.024). (4) Conclusions: Female gender, smoking, neck pain, and unsteadiness when moving the head are factors related to headache in university students.

Percutaneous Electrolysis in the Treatment of Lateral Epicondylalgia: A Single-Blind Randomized Controlled Trial

Few studies have considered the effects of percutaneous electrolysis (PE) in the treatment of lateral epicondylalgia (LE). For this reason, the objective of this study was to compare the effects of PE with an evidence-based approach—trigger point dry needling (TDN)—in patients with LE. A randomized controlled trial was conducted in which 32 participants with LE were randomly assigned to two treatment groups, the PE group (n = 16) and the TDN group (n = 16). Both groups received four therapy sessions and an eccentric exercise program to be performed daily. The numerical pain rating scale (NPRS), pressure pain thresholds (PPT), quality of life, and range of motion were measured before treatment, at the end of treatment, and at one- and three-month follow-ups. Significant between-group mean differences were found after treatment for NPRS (p < 0.001) and flexion movement (p = 0.006). At one-month follow-up, significant mean differences between groups were found for NPRS (p < 0.001), PPT (p = 0.021), and flexion (p = 0.036). At three-months follow-up, significant mean differences between groups were found for NPRS (p < 0.001), PPT (p = 0.004), and flexion (p = 0.003). This study provides evidence that PE could be more effective than TDN for short- and medium-term improvement of pain and PPTs in LE when added to an eccentric exercise program.

Effectiveness of Percutaneous Electrolysis in Supraspinatus Tendinopathy: A Single-Blinded Randomized Controlled Trial

Supraspinatus tendinopathy is one of the most common causes of shoulder pain. Many studies support conservative treatments such as exercise, trigger point dry needling or corticosteroid injections. Otherwise, a minimally invasive approach with percutaneous electrolysis (PE) has also been used successfully in shoulder pain, although evidence about its long-term effects is scarce. The aim of this trial was to determine the effects of PE on supraspinatus tendinopathy compared with trigger point dry needling (TDN). Thirty-six patients with supraspinatus tendinopathy were randomly assigned to either a PE group (n = 18) or a TDN group (n = 18). Both groups also performed eccentric exercises. The main outcome to be measured was the Numerical Pain Rating Scale (NPRS), but the shoulder range of motion (ROM) and trigger point pressure pain threshold (PPT) were also considered. A one-year follow-up was conducted. Significant differences favoring the PE group were found regarding pain at one-year follow-up (p = 0.002). The improvement achieved in the PE group was greater in the NPRS (p < 0.001), proximal PPT, middle PPT, distal PPT (all p < 0.001) and ranges of movement. PE seems to be more effective than TDN in relieving pain and improving ROM and PPT supraspinatus values in patients with supraspinatus tendinopathy, both right after treatment and at one-year follow-up.

Visual Verticality Perception in Spinal Diseases: A Systematic Review and Meta-Analysis

Patients diagnosed with traumatic or non-traumatic spinal pain and idiopathic scoliosis frequently suffer from imbalance. The evaluation of the perception of verticality by means of visual tests emerges as a quick and easy tool for clinical management of the balance disorders. Several studies have assessed the visual perception of verticality in spinal diseases obtaining controversial results. The aim of our study is to analyze the perception of visual verticality in subjects with several spinal diseases in comparison with healthy subjects. A meta-analysis was carried out. PubMed MEDLINE, Scopus, WoS, CINAHL, and SciELO databases were searched until January 2020. The standardized mean difference (SMD) was calculated to analyze differences between patients and healthy controls. Fifteen studies with a total of 2052 patients were included. In comparison with healthy subjects, a misperception of verticality was found in patients with spinal pain when the perception of the verticality was assessed with the rod and frame test (SMD = 0.339; 95% confidence interval (CI) = 0.181, 0.497; p < 0.001). It seems that the perception of visual verticality is not altered in patients with idiopathic scoliosis (p = 0.294). The present meta-analysis shows a misperception of visual verticality only in patients with spinal pain.

Vacuum myofascial therapy device for non-specific neck pain. A single blind randomized clinical trial

OBJECTIVES

This study aimed to investigate the efficacy of a vacuum myofascial therapy device (VT) for improving pressure pain thresholds (PPTs), range of motion (ROM), neck pain-related disability, pain, and quality of life in patients with non-specific neck pain.

METHODS

A randomized controlled trial in which thirty-eight participants with non-specific neck pain (NP) were randomly assigned to either an experimental (VT) or a comparison physical therapy program (PTP) group. The VT group (n = 19) received five sessions of treatment with a vacuum myofascial therapy device while the PTP group (n = 19) received five sessions of massage, ultrasound therapy (US), and transcutaneous electric nerve stimulation (TENS) over two weeks. The outcome measures were the numerical pain rating scale (NPRS), range of motion, quality of life (SF-12), neck disability Index (NDI), and PPTs at the end of treatment and at one-month follow-up.

RESULTS

Although both groups experienced improvements in pain, neck disability, range of motion, and pressure pain, these only were statistically significant in the VT group. At one-month follow-up, the VT group still showed improvements in pain, neck disability, and range of motion.

DISCUSSION

Vacuum myofascial therapy applied with a device offers similar results to other vacuum-based techniques such as cupping therapy. Moreover, in this device the parameters are digitally controlled, which allows for the precise reproduction of treatment.

Validation of the Spanish version of the migraine disability assessment questionnaire (MIDAS) in university students with migraine

BACKGROUND

The Migraine Disability Assessment (MIDAS) questionnaire is widely used to determine the degree of migraine-related disability of subjects. So far, and to the best of our knowledge, no Spanish version of this tool has been validated. The questionnaire comprises seven items, with the first five constituting the main scale while the sixth and seventh items referring, respectively, to the frequency and intensity of headache. The present study aims to analyze the clinimetric properties of the Spanish version of the MIDAS questionnaire in a population of university students.

METHODS

We performed a cross-sectional study of validation for this measuring instrument. A total of 153 subjects participated in the study. We analyzed construct validity using factor analysis, test-retest reliability by the Intraclass Correlation Coeficient (ICC), internal consistency, and concurrent validity with respect to the 12-Item Short Form Health Survey (SF-12).

RESULTS

Factor analysis revealed a two-factor structure. The questionnaire has good reliability for the MIDAS main-scale score ([ICC = 0.81; 95% CI: 0.63-0.90]), excellent reliability for headache frequency (ICC = 0.90; 95%; CI: [0.79-0.95]), and moderately good reliability for headache intensity (ICC = 0.63; 95% CI: [0.34-0.80]). The analysis also yielded good internal consistency results (α Cronbach = 0.797) and a moderate correlation between MIDAS-main scale and the physical component summary of SF-12 (Rho = - 0.326; p <  0.001).

CONCLUSIONS

The Spanish version of the MIDAS questionnaire is a valid and reliable tool to measure migraine-related disability in university subjects. The two additional items provide information that could help clinicians in making decisions.

Case Report: Conservative Treatment of Adolescent Idiopathic Scoliosis Can Alter the Perception of Verticality. A Preliminary Study

Adolescent idiopathic scoliosis (AIS) is a lateral curvature of the spine of at least 10° Cobb's angle of unknown etiology. Some studies have found that patients with AIS have a Visual Verticality (VV) perception similar to healthy controls. This study aimed to analyze VV perception and postural balance differences in patients with AIS depending on the management, either based on observation or conservative treatment. Eighteen patients with AIS were included in this study. Nine patients were managed based on observation. The other nine underwent conservative treatment, such as bracing or exercise. Subjective Visual Vertical (SVV) and posturographic parameters were measured and analyzed. In the SVV test, patients who underwent treatment showed poor constant error in absolute values and mean absolute error, with statistically significant differences (p < 0.05). Only the Romberg Quotient for sway area was within the limits of statistical significance for posturographic parameters, with a lower value for patients under observation. This study found worse perception of verticality in patients receiving some type of conservative treatment than patients receiving only observation; whereas posturography showed similar values in both observation and treatment groups. Our results can be interpreted as the effect of treatment on the previous verticality perception adapted to the curvature.

Misperception of the subjective visual vertical in neurological patients with or without stroke: A meta-analysis

BACKGROUND

The interpretation of the verticality of the environment is crucial for a proper body balance. The subjective visual vertical test (SVV) is a widely used method to determine the visual perception of the verticality, whose alteration has been related with poor functional status.

OBJECTIVE

To analyze the visual perception of the verticality in neurological patients in comparison with healthy controls.

METHODS

We searched PubMed, Scopus, and Scielo from the start of the databases until October 2017 and manually searched the reference lists of studies comparing SVV values between neurological patients and controls. Standardized mean difference (SMD) and subgroup analysis were used to analyze differences between neurological patients and healthy subjects and between stroke and non-stroke patients, respectively.

RESULTS

A total of 1,916 subjects from 31 studies were included. Neurological patients misestimate the true vertical in comparison with controls (SMD = 1.05; 95% CI: 0.81, 1.28). The misperception of the verticality was higher in stroke patients (SMD = 1.35; 95% CI: 1.02, 1.68) than in patients with other neurological conditions (SMD = 0.48; 95% CI: 0.29, 0.68).

CONCLUSIONS

Neurological patients showed a misperception of the verticality, estimated using the SVV. The neurological pathology that most alters the SVV is stroke.

The associations between menopausal symptoms and sleep quality in Spanish postmenopausal women

Objectives: Around the menopause, sleep disturbances frequently occur or worsen and are associated with decreased health quality and physical and psychological problems. The aim of this study was to analyze sleep quality and its association with the impact of menopausal symptoms in Spanish postmenopausal women. Methods: A total of 278 postmenopausal women (age 60.95 ± 8.01 years) participated in this cross-sectional study. The Medical Outcomes Study Sleep Scale (MOS-SS) and the Menopause Rating Scale (MRS) were used to analyze sleep quality and severity of menopausal symptoms, respectively. Anxiety and depression were measured using the Hospital Anxiety and Depression Scale. Results: The linear regression showed that a greater impact of menopausal symptoms (MRS total score) was associated with worse scores regarding sleep adequacy (p < 0.001, R² = 0.056), snoring (p = 0.020, R² = 0.036), awaken short of breath (p < 0.001, R² = 0.089), and quantity of sleep (p < 0.001, R² = 0.075) domains. Anxiety (p < 0.001) and worse somatic symptoms (p = 0.001) were related to greater sleep disturbances (R² = 0.164). We also found relationships of heightened psychological symptoms (p < 0.001) and low physical activity level (p = 0.003) with increased daytime somnolence (R² = 0.064). Finally, higher MRS total score and anxiety levels were associated with worse sleep quality assessed by MOS-SS Sleep Problems Index I (R² = 0.179, p < 0.001 and p = 0.001, respectively) and Sleep Problems Index II (R² = 0.146, p < 0.001 and p = 0.011, respectively). Conclusions: Anxiety and severity of menopausal symptoms were associated with poorer sleep quality. Furthermore, low physical activity level and worse psychological symptoms in menopause were predictors for increased somnolence. Therefore, screening for these factors in postmenopausal women is important, since they may be susceptible for intervention.

Tai Chi for Risk of Falls. A Meta-analysis

OBJECTIVES

To analyze the effectiveness of tai chi for falls prevention.

DESIGN

Systematic review and meta-analysis.

SETTING

Pubmed, Scopus, CINHAL, and Physiotherapy Evidence Database (PEDro) were searched to May 26, 2016.

PARTICIPANTS

Older adult population and at-risk adults.

INTERVENTION

Randomized controlled trials analyzing the effect of tai chi versus other treatments on risk of falls.

MEASUREMENTS

The incidence rate ratio (IRR) for falls incidence and hazard ratio (HR) for time to first fall.

RESULTS

The search strategy identified 891 potentially eligible studies, of which 10 met the inclusion criteria. There was high-quality evidence of a medium protective effect for fall incidence over the short term (IRR = 0.57; 95% CI = 0.46, 0.70) and a small protective effect over the long term (IRR = 0.87; 95% CI = 0.77, 0.98). Regarding injurious falls, we found very low-quality evidence of a medium protective effect over the short term (IRR = 0.50; 95% CI = 0.33, 0.74) and a small effect over the long term (IRR = 0.72; 95% CI = 0.54, 0.95). There was no effect on time to first fall, with moderate quality of evidence (HR = 0.98; 95% CI = 0.69, 1.37).

CONCLUSION

In at-risk adults and older adults, tai chi practice may reduce the rate of falls and injury-related falls over the short term (<12 months) by approximately 43% and 50%, respectively. Tai chi practice may not influence time to first fall in these populations. Due to the low quality of evidence, more studies investigating the effects of tai chi on injurious falls and time to first fall are required.

The Effect of Tai Chi on Reducing the Risk of Falling: A Systematic Review and Meta-Analysis

Tai Chi has frequently been used as a preventive measure against falling in at-risk populations. However, studies have yielded contradictory results, and literature reviews have considered only a small number of trials and have not addressed some key aspects, such as sources of heterogeneity and publication bias. This study includes 13 controlled trials published before June 2015 that analyzed the effectiveness of Tai Chi in fall prevention in populations of frail and at-risk adults. The effect measure used in this meta-analysis was absolute risk reduction (ARR) with a 95% confidence interval (CI). According to our findings, practice of Tai Chi significantly prevents the risk of falling (ARR, [Formula: see text]; 95% CI: [Formula: see text], [Formula: see text]). The heterogeneity of results across the trials was low, with a reduced risk of publication bias, and no significant effect differences were observed between studies comparing Tai Chi with other interventions or non-treatment. We therefore conclude that Tai Chi is more effective than other measures, or no intervention, for fall prevention in at-risk populations. Further research is warranted to analyze the consequences of falls and to study the episodes rather than the cases of falls.

Effects of an anaerobic lactic training session on the postural stability of athletes

AIM

The aim of this study was to analyze the short-term effects of a lactate-accumulation training session on postural stability.

METHODS

Fifteen athletes performed two trainings sessions (warm-up and lactic-training session). Before training (Pre), immediately after (Post(0min)), thirty minutes later (Post(30min)) and after 24 hours (Post(24h)), athletes were subject to a bipodal and a monopodal stabilometries and a lactate blood analysis to ensure a high stress level.

RESULTS

Variance analysis (α=0.05) showed that, in lactic training, athletes experienced an increase of length and velocity in post(0min), a decrease at post(30min) and a new decrease at post(24h), which was lower than basal values. In monopodal stability, left-leg support showed a decrease at post(0min) in anteroposterior plane of athletes after lactic training. Also, in both monopodal supports, athletes displayed higher values of length and velocity in post(0min) after lactic training, with a progressive decrease which was significant at Post(24h), when they reached baseline.

CONCLUSION

Right after anaerobic lactic training, center-of-pressure dispersion variables in bipodal stabilometry are worsened. Thirty minutes later, stabilometric variables are still deteriorated. At 24 hours, stabilometry is better than baseline. In monopodal support, dispersion values are worsened after lactic training and anteroposterior stability is impaired in left monopodal support, although the deterioration is less evident as time passes.

Effects of 6 Weeks of Balance Training on Chronic Ankle Instability in Athletes: A Randomized Controlled Trial

The objective of the present study was to determine the effectiveness of a 6-week balance training program on patients with Chronic Ankle Instability (CAI) in relation to the results obtained in Dynamic Balance, subjective feeling of instability and pain using a single-blind randomized controlled trial. 70 athletes were randomly assigned to control or intervention group. The control group performed their usual training, and the intervention group was administered the same usual activity in addition to a balance program. The paired t-test was performed to evaluate the change scores in each group. The t-test for independent samples was performed to evaluate between-group differences in change scores. Significance level was assigned for p-values less than 0.05 for all analyses. There were significant differences between groups in change scores in CAIT and all of the SEBTs reach distances (p<0.001) but not in Pain (p=0.586). The effect sizes were larger for the outcomes measures that showed significant differences. In the within-group change, the experimental groups showed larger effect sizes in CAIT, SEBT posteromedial and SEBT posterolateral, and moderate effect sizes in SEBT anterior. Exercise therapy training based on multi-station balance tasks led to significant improvements in dynamic balance and self-reported sensation of instability in patients with CAI.

Cross-cultural adaptation and validation of the Spanish version of the Cumberland Ankle Instability Tool (CAIT): an instrument to assess unilateral chronic ankle instability

The Cumberland Ankle Instability Tool (CAIT) is a valid instrument to determine the presence of chronic ankle instability (CAI) and to assess its severity. Self-report test is very useful for researchers and clinical practice, and CAI is a widespread tool. Nevertheless, there is lack of measurement instruments validated into Spanish, which represents a major difficulty for research dealing with a Spanish-speaking population. The questionnaire was cross-culturally adapted into Spanish. The psychometric properties tested in the Spanish version of the CAIT were measured for internal consistency, test-retest reliability, construct validity, criterion validity, and responsiveness in 108 participants who were recruited from several fitness centers. The Spanish version of the CAIT had high internal consistency (Cronbach's α = 0.766) and reliability (intraclass correlation coefficient = 0.979, 95 % confidence interval (CI) = 0.958-0.990). Correlation with the 36-item Short-Form Health Survey (SF-36) physical component summary score (rho = 0.241, p = 0.012) was greater than the SF-36 mental component summary score (rho = -0.162, p = 0.094). The construct validity shows three different factors in the questionnaire and good responsiveness with a mean change of -2.43 (95 % CI = -3.12 to 1.73, p < 0.0001) and a size effect of Cohen's d = 1.07. The Spanish version of the CAIT has been shown to be a valid and reliable instrument for measuring chronic ankle instability and constitutes a useful instrument for the measurement of CAI in the clinical setting in Spain.

Outpatients' perceptions of their experiences in musculoskeletal rehabilitation care

BACKGROUND

While patients' satisfaction with rehabilitation care is often measured, the knowledge of their experiences during delivery of care and of which characteristics may lead them to experience problems remains largely undocumented.

AIM

To assess the quality of patients' experiences receiving post-acute care for musculoskeletal disorders in outpatient rehabilitation settings. To describe the extent to which variations in reported quality of patients' experiences were related to their characteristics.

DESIGN

A cross sectional, self-reported survey.

SETTING

3 outpatient rehabilitation units.

POPULATION

Four hundred sixty-five outpatients. Mean age 39.4 (SD=11.9).

METHODS

A problem score (from 0 to 100%) of self-reported experiences was calculated on 7 specific aspects of care (belonging to organizational environment and professionals' attitudes and behaviors) and compared among participants' subgroups.

RESULTS

Mean scores of the organizational environment area showed higher amount of problems (43.3%) than the professionals' attitudes and behaviours area (34.7%). Two multivariate linear regression models (with adjusted R(2) 9.3% and 4.9%) indicated that older patients and those with high global rating change were less likely to experience problems in the two areas.

CONCLUSION

Problems on aspects of care were commonly experienced by patients with musculoskeletal disorders in outpatient rehabilitation settings. The age and health of patients were associated to these problems, but explained only a small variation in them.

CLINICAL REHABILITATION IMPACT

Surveys measuring patients' experiences can be used to monitor the actual performance of rehabilitation settings and to pinpoint the exact issues needing to be addressed to improve quality as well as to make comparison among centres.
