Filter by:Alzheimer's disease (AD) is a common neurodegenerative disease characterized by progressive cognitive impairment and memory impairment, and is also a major cause of global dementia, characterized by progressive decline in memory and daily living behavior. The incidence rate of AD increases with age. The prevalence rate of AD among men over 65 years old in China is 3.4%, and that of women is 7.7%, with a total prevalence rate of 5.9%. Among them, people over 65 years old can live for an average of 4 to 8 years after being diagnosed with Alzheimer's disease. According to statistics, there were approximately 5.98 million AD patients in China in 2005, reaching 10.2 million in 2020 and 22.5 million by 2040, making it the largest country with AD. At present, the treatment of AD is mostly limited to drug therapy, including Acetylcholine enzyme inhibitor, N-methyl-D-aspartate receptor antagonist and brain cell metabolism promoter. Although there are many types of drugs, their efficacy is not satisfactory, as they not only cannot effectively prevent and cure AD, but also cannot slow down the progression of AD. Regarding the surgical treatment of AD, neuromodulatory surgery, especially DBS (Deep Brain Electrical Stimulation), involves implanting stimulation electrodes into deep neural nuclei in the brain and performing electrical stimulation to change the excitability of the corresponding nuclei or neural circuits, and has been included in alternative treatment plans. In the past 20 years, DBS technology has been continuously explored for the treatment of AD, but an increasing number of clinical trials have shown that there is no effective target for AD-DBS. Therefore, there is an urgent need for new treatment methods to improve the current treatment status.
This post-marketing monocentric double-blind sham controlled crossover study will assess the efficacy of Rebox electrotherapy in the treatment of pain. Totally 72 patients will be treated with both real and sham Rebox device in a crossover design with a 1:1 ratio over a 6-week period. The degree of pain intensity reduction after the real Rebox stimulation will be evaluated in comparison with the sham stimulation. Moreover, differences in multidimensional aspects of pain will be compared between the real and sham stimulation.
It has been reported that 62% of all people with Spinal Cord Injury (SCI) have experienced faecal incontinence and that neurogenic bowel dysfunction (NBD) is a major sequela. As an alternative to abdominal massage or the use of suppositories, the electrical stimulation (ES) of the abdominal wall has been shown to be effective in decreasing the bowel transit time as well as decreasing constipation in children with slow-transit constipation. Due to the intrinsic nature of the guts' innervation, we expect to reproduce these positive effects in people with SCI through administration of neuromuscular electrical stimulation (NMES).
The aim of this study will be to determine the effects of different electrical muscle stimulation protocols on muscle stiffness and functional capacity in post-menopausal women. A randomized controlled clinical trial will be carried out. A total sample of 27 post-menopausal women will be recruited and divided into 3 groups which received high-frequency electrical muscle stimulation during 8 weeks, low-frequency electrical muscle stimulation during 8 weeks or no-intervention (control group). Outcome measurements will be stiffness assessed by sonoelastography and functional capacity assessed by the 30 seconds Chair-Stand Test before and after 8 weeks interventions.
In Canada, approximately 20% of patients with Major Depressive Disorder (MDD) have treatment-resistance and fail to respond to trials of pharmacotherapy or psychotherapy. Although the treatment of choice has historically consisted of electroconvulsive therapy (ECT), this is not always feasible or practical, and carries a risk of side-effects that may be unacceptable to certain patients. In this pragmatic, multi-site, placebo-controlled and double-blinded clinical trial, participants with ultra treatment-resistant MDD will be randomized to receive either active or sham transcranial direct current stimulation in addition to their usual treatment. Ultra treatment-resistant depression will be operationally defined as MDD that has failed to respond to at least five previous trials of antidepressants at sufficient doses, or ECT, or ketamine. Patients will receive a total of 30 active or sham treatment sessions (5 per week), for 30 minutes per session. In both groups, the anode will be placed over the left dorsolateral prefrontal cortex (position F3), and the cathode over the right dorsolateral prefrontal cortex (position F4). Patients in the sham group will receive electrical stimulation at 2 mA for less than 30 seconds, whereas patients in the active group will receive that level of stimulation for the entire duration of treatment. The study's primary outcome is the change in score on a clinician-graded depression inventory (the Montgomery-Asberg Depression Rating Scales). Secondary outcomes include change in scores on a self-administered depression rating scale and measurement of function scale. Information on language ability will also be collected, as will data on side-effects of treatment. Scores will be collected before the trial start, after every 10 sessions, and one month after trial completion.
Spasticity is a common manifestation of lesions of central motor pathways, such as after stroke, traumatic brain or spinal cord injury and in cerebral palsy and is associated with increased impairments and disabilities. Spasticity may be associated with pain and contractures, caused by muscle weakness, reduced muscle length and volume that add to the disability.Treatments of spasticity comprise physical therapy, pharmacological agents and surgical treatment. Recently, a systematic review concluded that transcutaneous, electric nerve stimulation may have beneficial effects on spasticity and activity performance after stroke, which lends support to the new treatment method Mollii, which will be evaluated in this study.The Mollii suit provides electric stimulation through multiple electrodes places in a tight fitting suit. This study relates to the clinical trials performed at the University department of rehabilitation medicine at Danderyd Hospital in Stockholm and comprises an initial study of effects on spasticity ("Mechanical substudy") and a following, exploratory treatment trial ("Clinical substudy") in patients with spasticity after stroke.
This study contributes to fundamental research investigating the role of the articulatory-motor integration and cerebro-acoustic coherence in speech comprehension. In a series of experiments non-invasive brain stimulation (NIBS) techniques including transcranial electric stimulation with alternating current waveforms (tACS) and transcranial magnetic stimulation (TMS) will be applied to the left ventral motor cortex (vMC) to test the contribution of this area to speech comprehension under challenging listening situations. As long as the exclusion criteria for TMS and tACS are strictly considered, only very minimal risks and no long-term effects are expected. There are no known risks associated with NIBS and pregnancy; however, since risks cannot be completely excluded, pregnant women will be excluded from participation. If a female participant is uncertain whether she is pregnant, she will be provided with a pregnancy test at no cost.
Low frequency pulsed current (PC) and medium frequency alternating current (Russian current - RC, 2.5 kHz) have been largely studied due to their clinical use. However, it is not clear which current is the most efficient due to the existente literature conflicts.Therefore, the purpose of this study is to compare the neuromuscular efficiency, evoked torque, current intensity, fatigability and level of discomfort between the PC and the RC in healthy young. The current types will be tested in the same participant by the intervention sequences randomization. On the first, second, third and fourth days, the maximum voluntary isometric contraction (MVIC), the current intensity level, discomfort level, evoked torque, and clinical and neuromuscular efficiency of each current will be evaluated. Anthropometric measurements will also be assessed on the first day. In addition, the current intensity required to produce a torque level of 20% of the MVIC, the current intensity required to generate a torque of 40 Nm and the maximum intensity tolerated by the participant will be evaluated. Three contractions will be recorded in each condition, and the level of discomfort will be assessed during the evoked contractions. Evoked torque will be evaluated at the maximum tolerated intensity level using the isokinetic dynamometer. Clinical and neuromuscular efficiency will be evaluated (1) at the current intensity necessary to evoke 20% MVIC, (2) at the current intensity necessary to generate 40 Nm, and (3) at the maximum tolerated current intensity. On the fifth and sixth days, muscle fatigue induced by the diferente current types will be evaluated. Fatigue will be evaluated with sufficient current intensity to generate 20% of the MVIC. MVIC will be performed before and after the fatigue protocol, and the fatigue will be determined by the relative variation of the MVIC before and after the fatigue protocol. Fatigue will also be evaluated through the evoked torque variation between the first and the last minute of the fatigue protocol, as well as by the total work generated in each protocol. Neuromuscular efficiency will be evaluated before and immediately after the protocol through (1) the ratio between input NMES current intensity and output evoked torque, (2) total work (area under the evoked force by time curves) generated during the fatigue protocol, and (3) by the changes in muscle architecture from rest to evoked contraction at the maximal current intensity.
The purpose of this study is to investigate the effect on the healing of pressure ulcers in elderly people using a care protocol plus the application of microcurrent patches during 12 hours per day compared to the effect of the same protocol plus placebo electric stimulation.
Intensive chemotherapy, with or without following autologous or allogeneic stem cell transplantation (HSCT), is often the only curative treatment option for patients with haematological malignancies, leave many survivors physically and psychologically impaired because of side effects, many caused by weeks of immobilisation. Electrical muscle stimulation (EMS) is a proven training tool to improve physical performance in seniors and patients with chronic disease. The investigators therefore intend to evaluate the safety and feasibility of EMS in patients undergoing autologous HSCT, allogeneic HSCT and intensive chemotherapy. To assess feasibility all patients are asked to document training time during hospitalization in an EMS diary. Furthermore, physical Performance will be measured using the 6-minute-walking distance (6MWD) and Short Physical Performance Battery (SPPB) as well as psychological performance using the Multidimensional Fatigue Inventory (MFI) and EORTC QLQ-C30 at the start of chemotherapy (T1) and when patients are discharged from hospital (T2). At the time intensive chemotherapy is started and all inclusion and no exclusion criteria are met, patients will receive an EMS device with electrodes and will be instructed on how to use the device. After that, baseline tests using the above mentioned tools will be performed. EMS will be conducted with a "Myopuls 2000" (Curatec Services GmbH, Moers, Germany) device using 13 cm x 5 cm electrodes. Electrodes are placed subsequently on both thighs and upper arms with instructions to stimulate each limb for at least 15 minutes on at least 5 days per week. Stimulation settings were as follows: 300 µs pulse width, 60 Hz frequency, 5 seconds on, 5 seconds off. The amplitude is initially set to elicit a visible muscle contraction and patients are encouraged to increase the amplitude as much as tolerated. After an initial training session, patients are to use the devices on their own and document their activities in an EMS diary. Patients are then asked to use EMS throughout their therapy in addition to physical therapy until the day of their discharge when the initially performed tests are repeated. The investigators hypothesis is, that EMS can be safely applied in patients undergoing intensive chemotherapy regimens and that patients are able to administer EMS by themselfs.
