Abstract
PURPOSE The aim of this study was to validate the Ethos Brief Index (EBI) in patients with Restless Legs Syndrome (RLS). METHODS A cross-sectional design, including 788 subjects with RLS (65% women, 70.8 years, SD 11.3) from the Swedish RLS Association, was used. A postal survey was sent out to collect data regarding socio demographics, comorbidities, and RLS-related treatment data. Questionnaires included were EBI, the Restless Legs Syndrome-6 Scale (RLS-6), Restless Legs Syndrome-Quality of Life questionnaire (RLSQoL), the Insomnia Severity Index (ISI), and the Epworth Sleepiness Scale (ESS). The validity and reliability of the EBI were investigated using Rasch and confirmatory factor analysis (CFA) models. Measurement invariance, unidimensionality, and differential item functioning (DIF) across age and gender groups, as well as insomnia, daytime sleepiness, RLS-related QoL and RLS severity were assessed. RESULTS The results supported the unidimensionality of the EBI in the CFA (i.e., explaining 61.5% of the variance) and the Rasch model. The reliability of the EBI was confirmed using composite reliability and Cronbach's alpha. No DIF was identified for gender, age, insomnia, daytime sleepiness, RLS severity or RLS-related QoL. CONCLUSION The EBI showed good validity and reliability and operated equivalently for male and female patients with RLS. Accordingly, healthcare professionals can use the EBI as a psychometrically sound tool to explore and identify patient-centered problems related to the whole life situation.

J Clin Neurosci 2024; 122:80-91. [PMID: 38489955 DOI: 10.1016/j.jocn.2024.02.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 02/02/2024] [Accepted: 02/27/2024] [Indexed: 03/17/2024]
Abstract
OBJECTIVE The primary aim was to estimate the pooled mean score of quality of life (QoL) (total, mental and physical health components) among patients with Restless Legs Syndrome (RLS). Secondary aims were to assess: (I) QoL differences for RLS vs. control groups, (II) heterogeneity and possible sources; and (III) moderating variables. METHODS Studies identified in PubMed, Scopus, Web of Science, and ProQuest between January 2000 and December 2022 were included. Methodological quality was assessed with Newcastle Ottawa Scale. The protocol was pre-registered (PROSPERO, CRD42023387318). RESULTS Twenty-seven studies (20121 participants, 12 countries) were included. The corrected pooled estimated mean score of QoL was 47.92 (27 studies, CI 95 %: 43.11 to 52.72, range 0-100, i.e., low-high QoL) and was marginally affected by publication year (increased 0.89 by each year, p = 0.12). The corrected pooled estimated mean score of the mental health component was 47.32 (17 studies, 95 % CI: 43.12 to 51.51, range 0-100) and influenced by RLS instrument (decreased with recent versions, p = 0.05). The corrected pooled estimated mean score of the physical health component was 39.08 (17 studies, 95 % CI: 33.05 to 45.10, range 0-100), with no statistically significant moderator. The pooled estimated QoL scores were statistically significantly lower in RLS patients compared to control groups with standardized mean difference (SMD) of -0.78, -0.57 and -0.50 respectively for overall QoL (24 studies), physical and mental health components (14 studies). Total QoL SMD was affected by proportion of women. CONCLUSION Low QoL was revealed among RLS patients, which was statistically significantly reduced compared to control groups.

Validation of two brief instruments (the SURE and CollaboRATE) to measure shared decision-making in patients with restless legs syndrome. J Sleep Res 2023:e14071. [PMID: 37909257 DOI: 10.1111/jsr.14071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/20/2023] [Accepted: 10/02/2023] [Indexed: 11/02/2023]
Abstract
Restless legs syndrome (RLS) is a common neurological disorder characterised by an urge to move arms and legs, usually associated with discomfort, pain, motor restlessness, and sleep disturbance. An individually adapted treatment is needed but difficult to optimise, which makes shared decision-making (SDM) important. However, brief validated instruments on how patients with RLS perceive their involvement in treatment decisions are lacking. Therefore, the aim was to validate two instruments, SURE (Sure of myself, Understand information, Risk-benefit ratio, Encouragement, i.e., to assess decisional conflict) and CollaboRATE (brief patient survey focused on SDM, i.e., to assess SDM), in patients with RLS. A cross-sectional design, including 788 participants with RLS (65% females, mean [SD] age 70.8 [11.4] years) from a national patient organisation for RLS, was used. A postal survey was sent out to collect data regarding weight, height, comorbidities, demographics, and RLS-related treatment data. The following instruments were included: the SURE, CollaboRATE, Restless Legs Syndrome-6 Scale, and eHealth Literacy Scale. Confirmatory factor analysis and Rasch models were used to assess the validity and reliability of the SURE and CollaboRATE. Measurement invariance, unidimensionality, and differential item functioning (DIF) across age, gender, and medication groups were assessed. The SURE and CollaboRATE were both identified as unidimensional instruments with satisfactory internal consistency. No DIF across age and gender was identified, while significant DIF was observed for both the SURE and CollaboRATE regarding medication use categories. However, both the SURE and CollaboRATE are potential instruments to be used in research, but also as reflection tools by healthcare professionals, patients, and students to explore and assess SDM, and support its development in clinical care.

Hydrotherapy and acupressure in restless legs syndrome: A randomized, controlled, 3-armed, explorative clinical trial. Medicine (Baltimore) 2023; 102:e34046. [PMID: 37390284 PMCID: PMC10313283 DOI: 10.1097/md.0000000000034046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 05/30/2023] [Indexed: 07/02/2023] Open
Abstract
BACKGROUND Restless legs syndrome (RLS) is a common neurological disease that has a significant impact on daily activities and quality of life, for which there is often no satisfactory therapy. Complementary medicine, such as acupressure and hydrotherapy, is used to treat patients with RLS; however, the clinical evidence is unclear. This study aims to investigate the effects and feasibility of self-administered hydrotherapy and acupressure in patients with RLS. METHODS This is a randomized, controlled, open-label, exploratory, clinical study with 3 parallel arms, comparing both self-applied hydrotherapy (according to the German non-medical naturopath Sebastian Kneipp) and acupressure in addition to routine care in comparison to routine care alone (waiting list control) in patients with RLS. Fifty-one patients with at least moderate restless-legs syndrome will be randomized. Patients in the hydrotherapy group will be trained in the self-application of cold knee/lower leg affusions twice daily for 6 weeks. The acupressure group will be trained in the self-application of 6-point-acupressure therapy once daily for 6 weeks. Both interventions take approximately 20 minutes daily. The 6-week mandatory study intervention phase, which is in addition to the patient preexisting routine care treatment, is followed by a 6-week follow-up phase with optional interventions. The waitlist group will not receive any study intervention in addition to their routine care before the end of week 12. Outcome parameters including RLS-severity, disease and health-related quality of life (RLS-QoL, SF-12), Hospital Anxiety and Depression Score in German version, general self-efficacy scale, and study intervention safety will be measured at baseline and after 6 and 12 weeks. The statistical analyses will be descriptive and exploratory. CONCLUSION In the case of clinically relevant therapeutic effects, feasibility, and therapeutic safety, the results will be the basis for planning a future confirmatory randomized trial and for helping to develop further RLS self-treatment concepts.

J Sleep Res 2023; 32:e13783. [PMID: 36600470 DOI: 10.1111/jsr.13783] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 10/24/2022] [Accepted: 10/24/2022] [Indexed: 01/06/2023]
Abstract
This systematic review, meta-analysis and meta-regression assessed the prevalence of restless legs syndrome (RLS) in the general adult population. Studies identified in Scopus, PubMed, Web of Science, and PsycInfo between January 2000 and February 2022 were included if they used a case-control or cross-sectional design and reported data regarding the prevalence of RLS. The protocol was pre-registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42022300709). A total of 97 studies including 483,079 participants from 33 different countries met the eligibility criteria. The Newcastle Ottawa Scale was used to evaluate the methodological quality, and the fill-and-trim method was used to correct probable publication bias, while the jack-knife method was performed to assess small study effect. The corrected overall pooled prevalence of RLS was 3% (95% confidence interval [CI] 1.4%-3.8%). The pooled prevalence of RLS syndrome was affected by methodological quality (no data from non-respondents in the included studies), gender (higher among women), study design (lower prevalence in case-control versus cohort and cross-sectional studies). The figures for corrected pooled prevalence among men, women, alcohol consumers and smokers were 2.8% (95% CI 2%-3.7%); 4.7% (95% CI 3.2%-6.3%); 1.4% (95% CI 0%-4.2%); and 2.7% (95% CI 0%-5.3%), respectively. The prevalence among male and female participants was lower in community-based versus non-community-based studies. Moreover, the prevalence was higher in developed versus developing countries and among elders versus adults. In conclusion, RLS is a common disorder in the general adult population, with a higher prevalence in women; however, prevalence data are affected by study design and quality.

A Narrative Review of the Lesser Known Medications for Treatment of Restless Legs Syndrome and Pathogenetic Implications for Their Use. Tremor Other Hyperkinet Mov (N Y) 2023; 13:7. [PMID: 36873914 PMCID: PMC9983500 DOI: 10.5334/tohm.739] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 02/11/2023] [Indexed: 03/06/2023] Open
Abstract
Background There are several well-known treatments for Restless Legs Syndrome (RLS), including dopamine agonists (pramipexole, ropinirole, rotigotine), anticonvulsants (gabapentin and its analogs, pregabalin), oral or intravenous iron, opioids and benzodiazepines. However, in clinical practice, treatment is sometimes limited due to incomplete response or side effects and it is necessary to be aware of other treatment options for RLS, which is the purpose of this review. Methods We performed a narrative review detailing all of the lesser known pharmacological treatment literature on RLS. The review purposefully excludes well-established, well-known treatments for RLS which are widely accepted as treatments for RLS in evidence-based reviews. We also have emphasized the pathogenetic implications for RLS of the successful use of these lesser known agents. Results Alternative pharmacological agents include clonidine which reduces adrenergic transmission, adenosinergic agents such as dipyridamole, glutamate AMPA receptor blocking agents such as perampanel, glutamate NMDA receptor blocking agents such as amantadine and ketamine, various anticonvulsants (carbamazepine/oxcarbazepine, lamotrigine, topiramate, valproic acid, levetiracetam), anti-inflammatory agents such as steroids, as well as cannabis. Bupropion is also a good choice for the treatment of co-existent depression in RLS because of its pro-dopaminergic properties. Discussion Clinicians should first follow evidence-based review recommendations for the treatment of RLS but when the clinical response is either incomplete or side effects are intolerable other options can be considered. We neither recommend nor discourage the use of these options, but leave it up to the clinician to make their own choices based upon the benefit and side effect profiles of each medication. Summary Clinicians should first follow evidence-based reviews for RLS but when response is incomplete and side effects intolerable, other medications can be considered. We do not make a recommendation on these options but leave it up to the clinician to make their own choice based upon the benefit and side effect profiles of each medication.

Abstract
Background: There is currently no definitive cure for restless legs syndrome (RLS), and the common treatments are only used to reduce symptoms. Mindfulness-based stress reduction (MBSR) is an intervention that has shown beneficial effects in many mental and physical disorders.Purpose: This study aimed to determine the effect of MBSR on RLS in hemodialysis patients.Methods: This study was a randomized clinical trial involving 60 hemodialysis patients with RLS recruited by convenience sampling each group. Inclusion criteria were patients with RLS diagnosis, age 18-65, Hb>10, no cognitive disorders, ability to read and write, no vision or hearing problems, and history of hemodialysis ≥6 months. The intervention group received eight sessions of the MBSR program, and the control group received routine care in a government dialysis center. International Restless Legs Syndrome Scale and Restless Legs Syndrome Severity Scale were used to measure RLS. Statistical analyses were conducted using independent and pair t-test and ANCOVA.Results: Significant difference was found in the severity the RLS (Mean(SD) score) between the intervention group (12.90(4.58)) and the control group (22.27(4.19)) (95% CI:-11.66 to -7.08, p<0.0001). The effect size between groups was obtained based on Cohen’s d of 2.13.Conclusion: MBSR showed a significant reduction in the severity of RLS in hemodialysis patients. This preliminary study suggests that MBSR can be a promising treatment option in the management of RLS patients.

Abstract
BACKGROUND Rapid effects of acupoint injection (acuinjection) at 4 acupoints (4P) (ST36, GB41, SP6, and BL60) on legs presenting sensory symptoms and motor signs in restless legs syndrome (RLS) were first described in a case report. This study aimed to confirm the beneficial effects of acuinjection. METHODS A randomized, controlled, single-blinded, prospective crossover study was conducted during 2018 to 2021. Adult volunteers (age ≥ 20 years) with RLS symptoms for > 2 weeks were included. Eight adults were enrolled and randomized to receive acuinjection (Verum group) or sham injection (Sham group). The effects of acuinjection on discomfort and periodic leg movement (PLM) were evaluated using the suggested immobilization test in a crossover design. The acupoint used was 4P, and normal saline solution (0.1-0.25 mL) was injected in both groups. Leg discomfort was measured using the visual analog scale (VAS), and PLM was measured using an electromyogram. To compare the VAS scores between the groups, repeated measures analysis of variance was used, and the Student t test was used to assess the mean discomfort score (MLDS: average of the 6 VAS scores) and PLM index (PLMI) (defined as the degree of PLM/hour). RESULTS A significant difference in the VAS score was observed; however, no significant difference was noted in the PLMI between the groups. The MLDS was significantly lower in the Verum group than in the Sham group. CONCLUSION Acuinjection at 4P remarkably inhibited leg discomfort in patients with RLS. Despite the drastic PLM suppression in 1 patient by acuinjection, a statistically significant inhibition of PLM was not confirmed. The results of our study can be applied easily and safely in clinical situations where it is necessary to temporarily reduce or eliminate RLS symptoms.

Abstract
OBJECTIVES Restless legs syndrome (RLS) has a significant effect on sleep and quality of life. Delays in diagnosis and treatment are frequent due to a lack of awareness. In this study, a clinical analysis was performed to examine the relationship between sleep, mood, and cognitive function in RLS. METHODS According to the Pittsburgh Sleep Quality Index score (PSQI), patients with RLS were divided into a sleep disorders group (SD, PSQI > 7) and non-sleep disorders group (NSD, PSQI ≤ 7). Healthy controls were selected as a control group matched for age, cultural background, and marital status. We compared differences between the three groups using the Hamilton Anxiety Scale (HAMA), Hamilton Depression (HAMD), Mini-Mental State Examination (MMSE), and Montreal Cognitive Assessment (MoCA). The SD and NSD groups were also assessed with the Restless Leg Syndrome Rating Scale (RLSRS) and the severity of RLS between the two groups was compared. The analysis used t-test, ANOVA, and Pearson correlation. RESULTS (1) Among the 54 RLS patients, 30 people in the control group, 35 patients with sleep disorders (SD, 65%), and 19 patients without sleep disorders (NSD, 35%), there were no significant differences in age, educational level, marital status, or trauma history. (2) The comparison results of the case group (SD and NSD) and the control group showed highly significant differences (P < 0.01) in the PSQI-HAMA-HAMD score but no significant differences between the NSD group, the SD group, and the control group in MMSE score. There was no difference between the NSD group and the control group in the MoCA, but a significant difference (P < 0.05) between the SD group and the control group was found. (3) The comparison between the NSD and the SD groups revealed significant differences in the RLSRS, HAMA, and HAMD scores (P < 0.05), but there were no statistical differences (P > 0.05) between two groups on MMSE and MoCA score. (4) Correlation and regression showed that there was a linear correlation between PSQI scores and RLSRS and HAMD scores in patients with RLS (P < 0.05). The regression equation was PSQI = - 2.393 + 0.494 RLSRS + 0.170 HAMD. CONCLUSIONS RLS patients were prone to sleep disorders, anxiety, and depression. Sleep disorders increased with the severity of the RLS and had some influence on the patient's cognitive function. Sleep disorders were closely related to RLSRS and HAMD.
