Feasibility of a rhythmic auditory stimulation gait training program in community-dwelling adults after TBI: A case report.

BACKGROUND: Traumatic brain injury has multiple impacts on gait including decreased speed and increased gait variability. Rhythmic auditory stimulation (RAS) gait training uses the rhythm and timing structure of music to train and ultimately improve slow and variable walking patterns. OBJECTIVE: To describe the feasibility of RAS gait training in community-dwelling adults with traumatic brain injury (TBI). A secondary objective is to report changes in spatiotemporal gait parameters and clinical measures of balance and walking endurance. METHODS: Two individuals with a TBI participated in nine sessions of gait training with RAS over a 3-week period. At baseline, post-training and 3-week follow-up, spatiotemporal parameters of walking were analyzed at preferred pace, maximum pace and dual-task walking conditions. Secondary outcomes included the Community Balance and Mobility Scale and the 6-Minute Walk Test. Feasibility was assessed using reports of physical fatigue, adverse event reporting, and perceived satisfaction. RESULTS: Both participants completed all 9 planned intervention sessions. The sessions were well tolerated with no adverse events. Participant 1 and 2 exhibited different responses to the intervention in line with the therapeutic goals set with the therapist. Participant 1 exhibited improved speed and decreased gait variability. Participant 2 exhibited reduced gait speed but less fatigue during the 6MWT. CONCLUSIONS: RAS was found to be a safe and feasible gait intervention with the potential to improve some aspects of gait impairments related to gait speed, gait variability, dynamic balance and walking endurance. Further investigation including a pilot randomized controlled trial is warranted.

Electrophysiological and Clinical Improvement in Non-Invasive Treatment of Carpal Tunnel Syndrome.

BACKGROUND AND OBJECTIVE: Carpal tunnel syndrome (CTS) is the most common form of nerve entrapment. Clinically, various signs and symptoms compare due to overexposure to mechanical vibrations transmitted to the wrist bones and cartilage, resulting in compression of the sensory and motor nerve fibers of the median nerve. Early symptoms include nocturnal paresthesia and electromyography reveals reduced sensory nerve conduction velocity. Aim of this study was to evaluate the efficacy of a dietary integrator composed of acetyl-L-carnitine, α-lipoic acid, quercetin, bromelain, pantothenic acid, C and B1 and B2 and B6 and B12 vitamins in patients with early (minimal) carpal tunnel syndrome. METHODS: 36 patients (28 female and 8 male) with early CTS characterized by sensory nerve demyelination and inflammation of the transverse carpal ligament. Patients were divided into two groups, group A (18 patients received physical therapy) and group B (18 patients received physical therapy and an oral integrator). Clinical (sleep quality questionnaire to measure severity of paresthesia) and neurophysiological assessment (Sensory Nerve Conduction Velocity) performed at baseline, and then at 30 and 60 days after treatment. RESULTS: Sleep quality and Sensory Nerve Conduction Velocity data analysis show improvement in both groups at 30 and 60 days, with statistical difference between them in both time of analysis. CONCLUSION: In the early CTS, with sensory fibers damage, use of dietary integrator, such as Micronil Dol®, composed of acetyl-L-carnitine, α-lipoic acid, quercetin, bromelain, pantothenic acid, C and B1 and B2 and B6 and B12 vitamins can be effective in quick recovery of median nerve sensory.

Effects of concomitant neuromuscular electrical stimulation during repetitive transcranial magnetic stimulation before repetitive facilitation exercise on the hemiparetic hand.

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) and Repetitive facilitative exercise (RFE) improves motor impairment after stroke. OBJECTIVE: To investigate whether neuromuscular electrical stimulation (NMES) can facilitate the effects of rTMS and RFE on the function of the hemiparetic hand in stroke patients. METHODS: This randomized double-blinded crossover study divided 20 patients with hemiparesis into two groups and provided treatment for 4 weeks at 5 days/week. NMES-before-sham group and NMES-following-sham group performed NMES sessions and sham NMES sessions for each 2 weeks. Patients received NMES or sham NMES for the affected extensor muscle concurrently with 1 Hz rTMS for the unaffected motor cortex for 10 min and performed RFE for 60 min. The Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), Box and Block Test (BBT) and Modified Ashworth Scale (MAS) were used for evaluation. RESULTS: FMA and ARAT improved significantly during both sessions. The gains in the BBT during an NMES session were significantly greater than those during a sham NMES session. MAS for the wrist and finger significantly decreased only during an NMES session. CONCLUSIONS: NMES combined with rTMS might facilitate, at least in part, the beneficial effects of RFE on motor function and spasticity of the affected upper limb.

Efficacy of Biofeedback for Medical Conditions: an Evidence Map.

BACKGROUND: Biofeedback is increasingly used to treat clinical conditions in a wide range of settings; however, evidence supporting its use remains unclear. The purpose of this evidence map is to illustrate the conditions supported by controlled trials, those that are not, and those in need of more research. METHODS: We searched multiple data sources (MEDLINE, PsycINFO, CINAHL, Epistemonikos, and EBM Reviews through September 2018) for good-quality systematic reviews examining biofeedback for clinical conditions. We included the highest quality, most recent review representing each condition and included only controlled trials from those reviews. We relied on quality ratings reported in included reviews. Outcomes of interest were condition-specific, secondary, and global health outcomes, and harms. For each review, we computed confidence ratings and categorized reported findings as no effect, unclear, or insufficient; evidence of a potential positive effect; or evidence of a positive effect. We present our findings in the form of evidence maps. RESULTS: We included 16 good-quality systematic reviews examining biofeedback alone or as an adjunctive intervention. We found clear, consistent evidence across a large number of trials that biofeedback can reduce headache pain and can provide benefit as adjunctive therapy to men experiencing urinary incontinence after a prostatectomy. Consistent evidence across fewer trials suggests biofeedback may improve fecal incontinence and stroke recovery. There is insufficient evidence to draw conclusions about effects for most conditions including bruxism, labor pain, and Raynaud's. Biofeedback was not beneficial for urinary incontinence in women, nor for hypertension management, but these conclusions are limited by small sample sizes and methodologic limitations of these studies. DISCUSSION: Available evidence suggests that biofeedback is effective for improving urinary incontinence after prostatectomy and headache, and may provide benefit for fecal incontinence and balance and stroke recovery. Further controlled trials across a wide range of conditions are indicated.

Aquatic Exercise Program for Individuals With Osteoarthritis: Pain, Stiffness, Physical Function, Self-Efficacy.

PURPOSE: This research was conducted to determine the effects of an aquatic exercise program on pain, stiffness, physical function, and self-efficacy in individuals with osteoarthritis. DESIGN: A randomized controlled trial. METHODS: Participants in the experimental group participated in the aquatic exercise program three times a week for 8 weeks; participants in the control group did not. FINDINGS: The mean scores of the experimental group on the pain, stiffness, and difficulty in carrying out physical functions subscales of the Western Ontario and McMaster Universities Osteoarthritis Index decreased significantly, whereas those of the control group decreased very little. The mean scores of the experimental group on the Arthritis Self-Efficacy Scale and the isokinetic muscle strength measurements increased, but those of the control group did not change in the final measurements. The difference between the groups was statistically significant. CONCLUSIONS: Through the study, it was determined that the aquatic exercise program decreased pain, stiffness, and difficulty in carrying out physical functions and increased self-efficacy and muscle strength of individuals with osteoarthritis. CLINICAL RELEVANCE: The aquatic exercise program can be used by nurses as a reference in the management of osteoarthritic patients' health status.

Effectiveness of Kinesio Taping in Patients With Chronic Nonspecific Low Back Pain: A Systematic Review With Meta-analysis.

STUDY DESIGN: Systematic review. OBJECTIVE: To investigate the effects of Kinesio Taping (KT) in patients with nonspecific low back pain. SUMMARY OF BACKGROUND DATA: KT is widely used in patients with low back pain. METHODS: We conducted searches on PubMed, EMBASE, PEDro, SciELO, and LILACS up to February 26, 2018. We included only randomized controlled trials (RCTs) in adults with chronic nonspecific low back pain that compared KT to no intervention or placebo as well as RCTs that compared KT combined with exercise against exercise alone. The methodological quality and statistical reporting of the eligible trials were measured by the 11-item PEDro scale. The quality of the evidence was assessed using the GRADE classification. We considered pain intensity and disability as the primary outcomes. Whenever possible, the data were pooled through meta-analysis. RESULTS: We identified 11 RCTs for this systematic review (pooled n = 743). Two clinical trials (pooled n = 100) compared KT to no intervention at the short-term follow-up. Four studies compared KT to placebo (pooled n = 287) at short-term follow-up and two trials (pooled n = 100) compared KT to placebo at intermediate-term follow-up. Five trials (pooled n = 296) compared KT combined with exercises or electrotherapy to exercises or spinal manipulation alone. No statistically significant difference was found for most comparisons. CONCLUSION: Very low to moderate quality evidence shows that KT was no better than any other intervention for most the outcomes assessed in patients with chronic nonspecific low back pain. We found no evidence to support the use of KT in clinical practice for patients with chronic nonspecific low back pain. LEVEL OF EVIDENCE: 1.

Pulmonary Rehabilitation and Exercise Training in Chronic Obstructive Pulmonary Disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common condition that is becoming increasingly prevalent. It affects 13.2% of the population over age 40 in Germany. In 2020, it will be the third most common cause of morbidity and mortality around the world. It markedly impairs the quality of life of those who suffer from it and presents a major economic challenge to the health-care system. METHODS: This review is based on pertinent publications retrieved by a selective literature search and on the authors' clinical experience. RESULTS: Pulmonary rehabilitation (PR) for patients with COPD is supported by evidence on the highest level. It is associated with statistically significant (p <0.001) and clinically relevant improvement in physical performance (6-minute walk distance: + 44 m; 95% confidence interval [33; 55]), shortness of breath (Chronic Respiratory Disease Questionnaire: +0.79 points [0.56; 1.03]), and the quality of life (Saint George´s Respiratory Questionnaire: -6.9 points [-9.3; -4.5]). The benefits of PR are especially evident after an acute exacerbation of COPD: it significantly lowers the rate of readmission to the hospital (odds ratio 0.22 [0.08; 0.58], p = 0.002) and improves physical performance ability (6-minute walk distance: + 62 m [38; 86] and the quality of life (Saint George´s Respiratory Questionnaire: -7.8 points [-12.1; -3.5]; p <0.001 for both). CONCLUSION: PR is an effective and cost-effective therapeutic intervention that improves physical performance ability, shortness of breath, and the quality of life in patients with COPD, but it has not yet been fully implemented as recommended in the relevant guidelines. There is a need for targeted, problem-oriented referral to a range of PR programs with problem-specific content. The necessary outpatient PR structures still need to be established in Germany.

[Are Visual Field Defects Reversible? - Visual Rehabilitation with Brains]. / Sind Gesichtsfelddefekte doch reversibel? ­ Visuelle Rehabilitation mit Gehirn.

Visual field defects are considered irreversible because the retina and optic nerve do not regenerate. Nevertheless, there is some potential for recovery of the visual fields. This can be accomplished by the brain, which analyses and interprets visual information and is able to amplify residual signals through neuroplasticity. Neuroplasticity refers to the ability of the brain to change its own functional architecture by modulating synaptic efficacy. This is actually the neurobiological basis of normal learning. Plasticity is maintained throughout life and can be induced by repetitively stimulating (training) brain circuits. The question now arises as to how plasticity can be utilised to activate residual vision for the treatment of visual field loss. Just as in neurorehabilitation, visual field defects can be modulated by post-lesion plasticity to improve vision in glaucoma, diabetic retinopathy or optic neuropathy. Because almost all patients have some residual vision, the goal is to strengthen residual capacities by enhancing synaptic efficacy. New treatment paradigms have been tested in clinical studies, including vision restoration training and non-invasive alternating current stimulation. While vision training is a behavioural task to selectively stimulate "relative defects" with daily vision exercises for the duration of 6 months, treatment with alternating current stimulation (30 min. daily for 10 days) activates and synchronises the entire retina and brain. Though full restoration of vision is not possible, such treatments improve vision, both subjectively and objectively. This includes visual field enlargements, improved acuity and reaction time, improved orientation and vision related quality of life. About 70 % of the patients respond to the therapies and there are no serious adverse events. Physiological studies of the effect of alternating current stimulation using EEG and fMRI reveal massive local and global changes in the brain. These include local activation of the visual cortex and global reorganisation of neuronal brain networks. Because modulation of neuroplasticity can strengthen residual vision, the brain deserves a better reputation in ophthalmology for its role in visual rehabilitation. For patients, there is now more light at the end of the tunnel, because vision loss in some areas of the visual field defect is indeed reversible.

Discord Between Approaches to Spinal and Extremity Disorders: Is It Logical?

Rapid advances in the basic, clinical, and behavioral sciences are molding developments in conservative management of musculoskeletal disorders. Curiously, there seems to be discord developing between approaches to the assessment and management of patients, depending on whether they present with an extremity or spinal disorder. This viewpoint will comment on examples of differences emerging in some current practices. The aim is not to present a scientific treatise about underpinning sciences and evidence-based practice or to comment on what is correct or incorrect. Rather, the aim is to stimulate thought on the seeming discord in clinical practice, with respect to both the clinical evaluation of, as well as management approaches to, extremity and spinal disorders.

Complementary and alternative healthcare use by participants in the PACE trial of treatments for chronic fatigue syndrome.

BACKGROUND: Chronic Fatigue Syndrome (CFS) is characterised by persistent fatigue, disability and a range of other symptoms. The PACE trial was randomised to compare four non-pharmacological treatments for patients with CFS in secondary care clinics. The aims of this sub study were to describe the use of complementary and alternative medicine (CAM) in the trial sample and to test whether CAM use correlated with an improved outcome. METHOD: CAM use was recorded at baseline and 52weeks. Logistic and multiple regression models explored relationships between CAM use and both patient characteristics and trial outcomes. RESULTS: At baseline, 450/640 (70%) of participants used any sort of CAM; 199/640 (31%) participants were seeing a CAM practitioner and 410/640 (64%) were taking a CAM medication. At 52weeks, those using any CAM fell to 379/589 (64%). Independent predictors of CAM use at baseline were female gender, local ME group membership, prior duration of CFS and treatment preference. At 52weeks, the associated variables were being female, local ME group membership, and not being randomised to the preferred trial arm. There were no significant associations between any CAM use and fatigue at either baseline or 52weeks. CAM use at baseline was associated with a mean (CI) difference of 4.10 (1.28, 6.91; p=0.024) increased SF36 physical function score at 52weeks, which did not reach the threshold for a clinically important difference. CONCLUSION: CAM use is common in patients with CFS. It was not associated with any clinically important trial outcomes.

[Current Conservative Treatment and Management Strategies of Skeletal Muscle Injuries]. / Konservative Therapie von Muskelverletzungen - Beurteilung aktueller Behandlungskonzepte.

Muscle injuries frequently occur during sport and are one of the commonest injuries. The diagnosis and treatment of muscle injuries impose high demands on medical treatment, in order to ensure successful regeneration and a rapid return to sport. Most of the injuries can be treated conservatively, as skeletal muscles have a high endogenous capacity for repair and regeneration. Conservative treatment includes initial on-field therapy. This is known as the "RICE" principle and is common and recommended for initial treatment for most sports injuries. The primary therapy target is to reduce pain, swelling and bleeding and thus to limit the initial inflammatory process and prevent further damage. During the first days after injury, brief immobilization helps to reduce the re-injury rate and accelerates the formation of granulation tissue. There are many possible additional treatments, including intramuscular injections, manipulation of the sacroiliac joint or rehabilitation programs, including stretching and strengthening. If the acute treatment phase is complete after 3 to 5 days, more active treatment, including trunk stabilisation, stretching and strengthening, can be started gradually. Despite their high prevalence, there have only been a few studies on the treatment and management of these injuries. The aim of this manuscript is to review the literature on the classification, pathobiology and treatment strategies for muscle injuries.

Can new technologies improve upper limb performance in grown-up diplegic children?

BACKGROUND: Few systematic studies describe rehabilitation trainings for upper limb in diplegic children with cerebral palsy (CP), who - especially once grown up - are often not considered as a target for rehabilitation interventions. AIM: In this pilot study, we describe the details and the effectiveness of an intensive, technology assisted intervention for upper limb. SETTING: The treatment combines the utilization of Armeo® Spring with a training focused on hand/finger fluency and dexterity in a pre-post treatment experimental design. POPULATION: Participants were ten school-aged children (mean age 11.2) with bilateral CP and diplegia, attending mainstream schools. METHODS: Participants underwent 40 therapy sessions in four weeks. Armeo® Spring measures, standardized motor and perceptual outcome indexes, as well as everyday life indicators were utilized to assess the effect of the intervention. RESULTS: Upper limb coordination, fluency and quality of movements mainly of hands and fingers significantly improved, with a good transferability to everyday life also in areas not specifically trained, such as self-care abilities and mobility. Probably due to the visual feedback provided by the virtual reality setting (which was all in one the context, the incentive and the product of activities), perceptual abilities significantly improved, too. CONCLUSIONS: Our study suggests the importance of intervention on upper limb even in milder CP diplegic forms and in relatively grown-up children. The possibility of modification at least partially relies on learning processes that are active all along development and benefit from stimulation. CLINICAL REHABILITATION IMPACT: Though further studies with control groups and follow-up perspective are needed to confirm, new technologies offer interesting possibilities to be integrated into new evidence-based rehabilitation models.

Managing urinary incontinence: what works?

Urinary incontinence is a common condition, which, although not life-threatening, impairs the health-related quality of life of affected individuals. All women complaining of incontinence require a basic assessment and those with complex or refractory symptoms may benefit from urodynamic studies. Initial treatment includes lifestyle advice, behavioral modifications, bladder retraining and pelvic floor muscle training. For those women with persistent stress urinary incontinence following conservative therapy, surgical management might be considered. The development of the minimally invasive, retropubic, synthetic, mid-urethral sling procedures has revolutionized stress incontinence surgery and reduced the popularity of 'traditional' procedures, such as colposuspension and autologous fascial sling. In an attempt to reduce further the morbidity, transobturator and single-incision slings have been introduced. While antimuscarinic agents are the mainstay of the current medical management of urgency urinary incontinence, a recently developed selective ß3-adrenergic receptor agonist (mirabegron) offers an alternative pharmacological option. Modalities such as intravesical botulinum toxin and neuromodulation (peripheral or sacral) are available to women with refractory urgency incontinence. Finally, when all other options have been explored and proven unsuccessful, inappropriate or not feasible, reconstructive surgery or catheter insertion might be considered as a last resort. The aim of this paper is to review conservative, medical and surgical management for urinary incontinence by using the best available evidence in the literature.

Update on interventions focused on symptom clusters: what has been tried and what have we learned?

PURPOSE OF REVIEW: Although clinicians and researchers acknowledge symptom clusters, the focus has been on relieving a single symptom. This review summarizes the recent literature on interventions that focus on relief of symptom clusters in patients with cancer. RECENT FINDINGS: Twelve intervention studies meeting inclusion criteria were published in 2011-2012. The timeframe was expanded to 2009-2012 and 24 studies met the criteria: 18 in early stage and 6 in advanced-stage cancer patients. Several cognitive behavioral therapy, complementary therapy, and exercise interventions demonstrated positive outcomes in relieving a variety of symptom clusters in several cancer types. Most psychoeducational interventions using traditional formats or those combined with automated clinician alerts demonstrated effectiveness in reducing a variety of clusters. Clusters that included fatigue and anxiety or depression were reduced by exercise in early stage patients and by methylphenidate in advanced-stage patients. Current NIH R01 funded studies verified the trends in the types of interventions being tested. SUMMARY: Few interventions have been tested and found to be effective in relieving the specific symptom clusters in early and advanced-stage cancer patients. Future research needs to expand our understanding of the mechanisms that initiate co-occurring symptoms. Mechanism-targeted interventions need to be identified and tested in homogeneous samples with specific symptom clusters. Interventions need to be replicated before guidelines can be established.

Exercise therapy for fibromyalgia.

Fibromyalgia syndrome, a chronic condition typically characterized by widespread pain, nonrestorative sleep, fatigue, cognitive dysfunction, and other somatic symptoms, negatively impacts physical and emotional function and reduces quality of life. Exercise is commonly recommended in the management of people with fibromyalgia, and interest in examining exercise benefits for those with the syndrome has grown substantially over the past 25 years. Research supports aerobic and strength training to improve physical fitness and function, reduce fibromyalgia symptoms, and improve quality of life. However, other forms of exercise (e.g., tai chi, yoga, Nordic walking, vibration techniques) and lifestyle physical activity also have been investigated to determine their effects. This paper highlights findings from recent randomized controlled trials and reviews of exercise for people with fibromyalgia, and includes information regarding factors that influence response and adherence to exercise to assist clinicians with exercise and physical activity prescription decision-making to optimize health and well-being.

El dolor lumbar en el año 2009 / Lumbar pain in 2009

Todo el mundo reconoce la frecuencia tan elevada de las lumbalgias y su importante repercusión socioprofesional. El dolor lumbar es una de las patologías más frecuentes en las consultas de medicina general y de los especialistas del aparato locomotor (traumatólogos, reumatólogos y rehabilitadores). Tiene características de epidemia en las sociedades más desarrolladas y ha sido denominado por algunos autores como la “enfermedad del siglo”. Entre las consultas médicas, después de los síntomas del resfriado le siguen inmediatamente los dolores de espalda.El mantenimiento en el empleo de los trabajadores que sufren de la espalda y la prevención de la lumbalgia crónica constituyen preocupaciones crecientes de los responsables de la salud pública en razón de los costes elevados que esta problemática de salud genera en la colectividad. Para hacer frente a este problema mayor de salud pública, la literatura científica, apoyándose principalmente en estudios escandinavos y norteamericanos, propone y considera muy importante la actuación médica precoz y adecuada de la lumbalgia en la fase aguda (AU)

Almost everyone will experience low back pain at some point in their lives and recognizes the very high frequency of lower back pain and its significant social and occupational impact. Low back pain is one of the most common conditions in general practice consultations and musculoskeletal specialists (orthopedists, rheumatologists and rehabilitation). It has characteristics of an epidemic in most developed societies, and has been dubbed by some as "disease of the century". Between doctor visits, after cold symptoms followed immediately back pain.The job retention of workers suffering from back and preventing chronic back pain are growing concerns of those responsible for public health because of the high costs this creates health problems in the community. To address this major public health problem, the scientific literature, relying mainly on studies Scandinavian and North American, proposes and attaches great importance to early and appropriate medical intervention in low back pain in the acute phase (AU)
