Filter by:Hemiparetic gait is characterized by strong asymmetries that could severely affect the quality of life of stroke survivors. This asymmetry is due to motor deficits in the paretic leg and the resulting compensations in the non-paretic limb. In this study, the investigators aim to evaluate the effect of actively promoting gait symmetry in hemiparetic patients by assessing the motion and muscular activity of both paretic and non-paretic lower limbs. To this end, the investigators use a unilateral active Knee-Ankle-Foot Orthosis able to assist the paretic limb of hemiparetic patients during gait. The system is able to synchronize its action with the movement of the unassisted joints, promoting a natural and intuitive interaction. The device generates assistance to induce a healthy gait pattern on the paretic leg. The hypothesis is that a proper and natural interaction between the user and the exoskeleton would enable the patients to consider the robot action as a part of their own gait capability, improving their gait quality as consequence. Hemiparetic asymmetry is not only due to impairments in the affected limb, but also it is the consequence of biomechanical compensatory mechanisms that might arose in the non-paretic leg. The aim of this study is to assess the adaptation process of the subject to the exoskeleton assistance, and to evaluate the effects of such human-robot interaction in both paretic and non-paretic legs.

To this end, the investigators use a unilateral active Knee-Ankle-Foot Orthosis able to assist the paretic limb of hemiparetic patients during gait. The system is able to synchronize its action with the movement of the unassisted joints, promoting a natural and intuitive interaction. The device generate the assistance according to two differents strategies: (1) Replicating the movement of the helathy leg or (2) Inducing a healthy gait pattern on the paretic leg. The hypothesis is that a proper and natural interaction between the user and the exoskeleton would enable the patients to consider the robot action as a part of their own gait capability, improving their gait quality as consequence. Hemiparetic asymmetry is not only due to impairments in the affected limb, but also it is the consequence of biomechanical compensatory mechanisms that might arose in the non-paretic leg. We aim to assess the adaptation process of the subject to the exoskeleton assistance, and to evaluate the effects of such human-robot interaction in both paretic and non-paretic legs.
For several years now, it has been demonstrated that the upper limb plays an important role in the function of an efficient and balanced gait pattern in healthy adults. After a stroke, the reduced muscle strength has a clear influence on the gait pattern, but also on the active movement possibilities of the upper limb. However, the role of the upper limb during gait is not sufficiently explored in the literature. The gold standard for motion analysis is a 3D analysis performed with infrared cameras capturing reflective markers during gait. Unfortunately, it is not possible for all people after a stroke to undergo this examination. On the one hand, patients must already have a certain degree of independence with regard to gait. On the other hand, not all centers have access to this expensive accommodation. There are some validated observation scales for people after stroke to describe the gait based on a 2D video image. This method is much more accessible and can be applied by any therapist. However, to date there has been little attention paid to the upper limb in these observation scales. Therefore, analogous to the observation scales for gait, an observation scale for the upper limb during gait was set up. The use of this scale can add value to the rehabilitation of people after a stroke. - The treatment team will receive information about the patient's complete movement pattern. - The arm will be more prominent when setting rehabilitation goals related to gait. This can lead to a positive effect on the gait pattern itself, but also to more attention being paid to the arm, which has a more difficult recovery than the leg after a stroke. The aim of the current study will be - to determine the inter and intra tester reliability of this visual observation scale - to investigate if the results of the visual observation scale correlate to a 3D assessment performed in a subgroup of participants
Ventilator-induced diaphragmatic dysfunction is a common issue in critically ill patients. Muscle stimulation has shown to have beneficial effects in muscle groups on the extremities. A non-invasive way to stimulate the diaphragm would be the electromagnetic stimulation but it is currently unclear if that is feasible. In this proof-of-concept trial the primary aim is to show that it is possible to induce a diaphragmatic contraction leading to an inspiration with a sufficient tidal volume via an external electromagnetic stimulation of the phrenic nerve in obese patients.
Recent studies have shown that completing bilateral simultaneous movements during upper extremity practice may result in facilitation of coactivation and interhemispheric activation of both the ipsilesional and contralesional brain areas, with one limb entraining the other and enabling the limbs to function as a unit. Other research has proposed that the use of virtual-reality (VR) activities during treatment sessions can improve upper extremity function following stroke as it is motivating, challenging, offers external feedback that may facilitate motor learning, and allows for the "high-intensity, repetitious practice necessary to drive recovery". Coupling bilateral simultaneous upper extremity movement and virtual-reality activities is the Bimanual Arm Trainer (BAT), a non-powered mechanical device by which the non-paretic upper extremity moves the paretic arm. The purpose of this study is to determine the effectiveness of the Bimanual Arm Trainer (BAT) compared to traditional occupational therapy treatment sessions as these relate to upper extremity functional return following stroke, as measured by scores on the Action Research Arm Test (ARAT) and Upper Extremity Fugl-Meyer Assessment (UE-FMA) measures. The investigators plan to use retrospective data for a pre-implementation group, comparing this data to prospectively collected post-implementation data. ARAT scores are routinely collected and will be used for comparison between groups. UE-FMA measures are commonly used in this area of research, and will be taken to provide additional context for the post-implementation group.
Post-stroke gait deviations contribute to significant functional disability, impaired walking ability and poor quality of life. Prior studies suggest that gait training with paretic lower limb loading may improve gait parameters and walking ability in post-stroke. However, most gait training methods used in these studies are not readily available, and studies using cheaper methods are limited.
To assess the incidence of hemi-diaphragmatic paresis following ultrasound-guided erector spinae plane (ESP) block
Postoperative respiratory complications are common complications of patients after cardiac surgery and increase morbidity and mortality and hospital length of stay. Diaphragmatic dysfunction accounts for between 2 and 15% of these complications. Diaphragmatic paresis is one of these dysfunctions and could be due to an intra-operative phrenic nerve injury or harvesting of a mammary artery responsible for diaphragmatic devascularization. It alters the ventilatory mechanics and causes acute respiratory distress often requiring the use of mechanical ventilation. The diagnosis of this dysfunction can be made by thoracic ultrasound with assessment of diaphragmatic excursion. For patient with paresis, ultrasound criteria is an excursion < 25 mm after deep inspiration for at least one of the two hemidiaphragms. This dysfunction is most often transient in the postoperative period, but it can also become persistent. Contract-Relax (CR) physical therapy technique can be applied to any muscle, providing muscle strengthening, neuromotor stimulation, and a gain in joint amplitude. Currently, post-cardiac surgery management of respiratory physiotherapy is the same for a patient with or without paresis. Moreover, the CR technique of the diaphragm is not part of this "standard" rehabilitation. The objective of this study is to determine if the CR technique associated with the current respiratory management allows an early rehabilitation of patients with diaphragmatic paresis after cardiac surgery.
Immediate effect of one-session Matrix Rhythm Therapy on the functional status and treatment satisfaction of hemiparetic patients will be investigated.
The aim of this study is to examine whether the administration of the TQL block cause motor block of the lumbar plexus and thereby quadriceps muscle weakness. The investigators hypothesise that the administration of a unilateral TQL block does not cause quadriceps muscle weakness compared to a placebo block.
