Filter by: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.
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.
It is estimated that about 30% of women cannot voluntarily contract the pelvic floor muscles (PFM). PFM training (PFMT) represents the first therapeutic option for the treatment of female urinary incontinence (UI), however the inability to contract this muscle makes PFMT unfeasible. The primary objective of this project is to evaluate clinically the efficacy of intravaginal electrical stimulation associated with verbal instructions to provide the ability of women to contract voluntary their PFM. The secondary objective is to evaluate the UI prevalence and impact on quality of life.
Currently, cancer is a disease of high incidence, already considered a public health problem. Among the most prevalent are head and neck neoplasms, and depending on the location and extent of the lesion, the treatments are surgery, chemotherapy and / or radiotherapy that have a great impact on the quality of life. Radiation therapy is a frequently chosen treatment, and depending on the dose of radiation, causes changes such as hyposalivation. There are techniques for salivary flow stimulation, however, most of the options involve the use of medications, which limits administration to part of the patients. Transcutaneous electric nerve stimulation (TENS) is an alternative that has been used to stimulate salivary flow, however there is a limited number of studies that have tested this technique after radiotherapy. The aim of this study was to verify the effect of TENS in increasing the salivary flow of individuals receiving radiotherapy to treat tumors of the head and neck. The sample will have 80 patients randomly divided into two groups: TENS group and Control group. In both groups, a quality of life questionnaire (UW-QOL) will be applied and a speech-language assessment will be performed. The hypothesis of this research is that TENS is effective in increasing the amount of saliva. Secondary outcomes involve the evaluation of the effect of this technique on the quality of life, mainly in the questions: speech, chewing, saliva and deglutition.
This study evaluates the effect of training with neuromuscular electrical stimulation (NMES) associated with vascular occlusion of the lower limbs, for increased strength and hypertrophy of the quadriceps muscle of professional basketball athletes.
