Background: Persons with stroke commonly have impairments associated with a reduction in functionality. Motor impairments are the most prevalent, causing an impact on activities of daily life. Objective: The aim of this study was to evaluate the effect of a session of dry needling (DN) applied to the upper extremity muscles on the sensorimotor function, hypertonia, and quality of life of persons with chronic stroke. Methods: A randomized, sham-controlled clinical trial was performed. Participants were randomly assigned into an intervention group that received a single session DN in the biceps brachii, brachialis, flexor digitorum superficialis and profundus, extensor digitorum, adductor pollicis and triceps brachii muscles, or into a control group that received the same treatment but with a sham DN intervention. Treatment outcomes included the Fugl–Meyer Assessment Scale for the upper extremity, the Modified Modified Ashworth Scale, and the EuroQol-5D questionnaire. Measurements were carried out before, immediately after, and 14 days after intervention. Results: Twenty-three persons participated in the study. Significant differences between groups were observed after the intervention in the total wrist–hand motor score (p = 0.023) and sensorimotor score (p = 0.022), for hypertonia in the elbow extensors both after treatment (p = 0.002) and at follow-up (p = 0.018), and in quality of life at follow-up (p = 0.030). Conclusions: A single session of DN improved total wrist–hand motor function and total sensorimotor function in persons with chronic stroke immediately after treatment, as well as quality of life 2 weeks after treatment.

Background and purpose: Brain function can be networked, and these networks typically present drastic changes after having suffered a stroke. The objective of this systematic review was to compare EEG-related outcomes in adults with stroke and healthy individuals with a complex network approach. Methods: The literature search was performed in the electronic databases PubMed, Cochrane and ScienceDirect from their inception until October 2021. Results: Ten studies were selected, nine of which were cohort studies. Five of them were of good quality, whereas four were of fair quality. Six studies showed a low risk of bias, whereas the other three studies presented a moderate risk of bias. In the network analysis, different parameters such as the path length, cluster coefficient, small-world index, cohesion and functional connection were used. The effect size was small and not significant in favor of the group of healthy subjects (Hedges’g = 0.189 [−0.714, 1.093], Z = 0.582, p = 0.592). Conclusions: The systematic review found that there are structural differences between the brain network of post-stroke patients and healthy individuals as well as similarities. However, there was no specific distribution network to allows us to differentiate them and, therefore, more specialized and integrated studies are needed.

Chronic non-specific low back pain (CNSLBP) is a highly prevalent musculoskeletal condition that has a great socioeconomic impact on health systems. Instead of focusing on mechanical causes and direct workload in the development of CNSLBP, genetics, psychosocial environment, lifestyle and quality of life are coming to the forefront in its approach. The main objective was to analyze whether interventions aimed at modifying lifestyle can be effective in improving pain intensity and functional disability in CNSLBP. A search in PubMed, Web of Science, Scopus and SportDiscus databases was performed. Both a univariate and a multivariate network meta-analysis were applied with the difference pre/post-treatment. A total of 20 studies were included for qualitative analysis, of which 16 were randomized clinical trials with a moderate–high methodological quality and were part of the quantitative analysis. The interventions that had the greatest effect in reducing pain intensity were cognitive therapy combined with functional exercise programs, lumbar stabilization exercise and resistance exercise; meanwhile, for functional disability, they were functional exercise programs, aerobic exercise and standard care. In conclusion, a multimodal intervention aimed at changing one’s lifestyle that encompasses cognitive, behavioral, and physical aspects seems to be highly effective in improving pain intensity and functional disability caused by CNSLBP; however, it is not yet known if these improvements are maintained in the long term.

Background: About 40% of patients who have had COVID-19 still have symptoms three months later whereas a 10% may experience physical and/or psychological consequences two years later. Therefore, it is necessary to perform preventive interventions when patients are discharged from the hospital to decrease the aforementioned sequelae. The purpose of this pilot-controlled trial will be to determine the efficacy of a rehabilitation program on functional status and psychosocial factors for post-COVID-19 patients when it is delivered through a tele-care platform versus a booklet-based rehabilitation. Methods: The estimated sample size will be of 50 participants who have been discharged after COVID-19 and have a level of fatigue equal or greater than 4 on the Fatigue Severity Scale. The primary outcome will be the severity of fatigue. Participants will be randomly allocated to an “asynchronous telerehabilitation group” or to a “booklet-based rehabilitation group”. Treatment in both groups will be the same and will consist of a combination of therapeutic exercise and an educative program. Treatment outcomes will be evaluated the last day of the intervention and at three- and six-months follow-up. Discussion: The telerehabilitation intervention appears to be a viable and efficacy option in decreasing severe fatigue and other fitness variables such as strength and aerobic capacity, similar to other traditional rehabilitation formats such as through an explanatory booklet. Clinical trial registration: This trial has been prospectively registered at clinialtrials.gov identifier: NCT04794036.

Background: Alterations in gait and muscular rigidity are common and disabling in persons with Parkinson’s disease (PD). Objective: The aim of this study was to determine whether a single dry needling (DN) session can promote changes in gait and muscle tone in the lower extremities as well as in the evolution of the disease in persons with PD. Methods: A randomized double-blind clinical trial was designed. Participants were randomly assigned to an intervention group (IG) that received a session of DN over the semitendinosus, medial gastrocnemius, soleus and rectus femoris muscles, or to a control group (CG) that received a session of sham DN in the same muscles. The effects of DN were assessed using the timed up and go test (TUG), 10 meter walk test (10MWT), 6 minute walk test (6MWT) and myotonometry before, immediately after, and 7 days after the intervention. Results: Thirty-three participants were analyzed aged 69.9 ± 7.2 years (mean ± SD; 39% female). There were no significant differences between the IG and CG for any outcomes. Significant differences were observed when comparing the Pre and Follow-up values in the IG for functional mobility of gait in the TUG (p = 0.049), gait speed in the 10MWT (p = 0.041) and muscle tone in the lower extremities by myotonometry (frequency (p = 0.027) and stiffness (p = 0.013)). By comparison, there were no significant within-group differences in the CG. Conclusion: A single session of DN had no measurable benefit compared to a single session of sham DN. Within-group changes in the IG suggested improvements in functional mobility of gait and gait speed, as well as changes in the muscle tone in the lower extremities of PD patients, which could be worthy of further exploration by future research.

Introduction: Dry needling (DN) has been shown to be effective for the treatment of upper extremity hypertonia in patients with stroke. Purpose: To evaluate the cost-effectiveness of DN in patients with stroke. Methods: A cost-effectiveness analysis was performed in a research study conducted at a Spanish public hospital where patients were classified into two groups with or without DN. Hypertonia was measured using the Modified Modified Ashworth Scale (MMAS), and quality of life (QOL) was assessed using the EuroQoL 5-dimension questionnaire. Data regarding the effects and costs of physiotherapy were presented by calculating the mean and 95% confidence interval. The health outcomes were evaluated considering the rate of responders to the treatment based on the MMAS. Spanish preference weights were used to estimate quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were calculated to determine the economic value of DN. Results: Eighty patients with stroke in the subacute stage of recovery were selected to participate in this study. Based on the rate of responders, the ICER of the DN group was very low. Despite the sensitivity analysis performed, the results of the ICUR were not encouraging. Discussion: Cost-effectiveness with responder rate results were favourable for the DN group and were confirmed by the sensitivity analysis according to levels of care. In addition, our findings revealed that 4 weeks of treatment could be more cost-effective than 8 weeks. DN treatment of the upper extremity appears to be cost-effective based on the rate of responders measured using the MMAS scale.
