INcobotulinumtoxina in ChIldren Upper and Lower Limb sPasticITy (INCIPIT)

Spastic Cerebral Palsy

Prospective, open-label, non-randomized, single-arm, dose titration, phase II study. The study will consist of three injection cycles. In each, an injection visit is followed by an observation period of 12 to 20 weeks. During cycle 1, a total body dose of 16U/kg (maximum 400U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. During cycle 2, a total body dose of 19U/kg (maximum 475U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. If a dose of 19U/kg is not justified (i.e., for clinical or safety reasons) but BoNT-A treatment is still needed (according to the clinical condition of patients) the same dose injected in cycle 1 (16U/Kg; maximum 400U) may be administered in the cycle 2. During cycle 3, a total body dose of 22U/kg (maximum 550U) of IncobotulinumtoxinA will be injected into the spastic muscles of the affected limbs. If a dose of 22U/kg is not justified (i.e., for clinical or safety reasons) but BoNT-A treatment is still needed (according to the clinical condition of patients) the same dose injected in cycle 2 (19U/Kg; maximum 475U) may be administered in the cycle 3.

Photo Biostimulation and Spasticity in Cerebral Palsy

Calf Muscle SpasticitySpastic Cerebral Palsy

the current study will address the spasticity in calf muscle secondary to cerebral palsy in children. As the spasticity can inversely affect muscle contraction, joint function, and consequently the function and quality of life, the current study will investigate the effect of adding photobiostimulation therapy to standard physiotherapy on muscle tone, ankle range of motion, gross motor function, plantar surface of the affected foot, and quality of life in patients with spastic cerebral palsy

Neurophysiological Evaluation of Muscle Tone

Muscle Tone AbnormalitiesRigidity3 more

The primary objective of this study is to apply a biomechanical system (the NeuroFlexor) associated with the EMG recording to study the physiological mechanisms that contribute to the regulation of muscle tone in healthy subjects and in patients with increased muscle tone. A second fundamental objective of this study is to monitor over time the changes in muscle tone that can be found physiologically in healthy subjects and pathologically in patients with spasticy and/or rigidity. A further objective of this study is the quantitative evaluation of the symptomatic effects of specific therapies in improving the impaired muscle tone. Clinical evaluation In this research project the investigators will recruit 20 patients with upper limb spasticity (regardless of the underlying disease responsible for the spasticity), 20 patients with Parkinson's disease characterized by stiffness of the upper limbs and 20 healthy control subjects. Patients will be recruited from the IRCCS Neuromed Institute, Pozzilli (IS). Participants will give their written informed consent to the study, which will be approved by the institutional ethics committee of the IRCCS Neuromed Institute, in accordance with the Declaration of Helsinki. All participants will be right-handed according to the Edinburgh handedness inventory (EDI) (Oldfield, 1971). Parkinson's disease will be diagnosed in accordance with the updated diagnostic criteria of the MDS (Postuma, RB et al. Validation of the MDS clinical diagnostic criteria for Parkinson's disease. Mov. Disord. Off. J. Mov. Disord. Soc. 33, 1601 -1608 (2018)., Nd). Clinical signs and symptoms of parkinsonian patients will be evaluated using the Hoehn & Yahr scale (H&Y), UPDRS part III (Patrick et al., 2001). The diagnosis of spasticity will be made through the neurological clinical evaluation of the patients and on the basis of the specific clinical history of the various pathologies underlying the spasticity itself (e.g. multiple sclerosis, stroke, spinal injuries). Spasticity will be assessed with the Modified Ashworth Scale "(MAS) (Harb and Kishner, 2021), the Modified Tardieu scale (MTS) (Patrick and Ada, 2006). Cognitive functions and mood, in both pathological conditions, will be evaluated using the clinical Mini-Mental State Evaluation (MMSE) scale (Folstein et al., 1975) and the Hamilton Depression Rating Scale (HAM_D) ( Hamilton, 1967). No participant must report pain problems and / or functional limitations affecting the upper limbs. Exclusion criteria: - insufficient degree of passive wrist movement (<30 ° in flexion and <40 ° in extension) - tension at rest during NeuroFlexor recordings - hand pathologies (neurological or rheumatological) - upper limb fractures in the previous six months - presence of peacemakers or other stimulators - pregnancy. All patients, and the group of healthy control subjects will have comparable anthropometric and demographic characteristics. Experimental paradigm Participants will be seated comfortably, with the shoulder at 45 ° of abduction, the elbow at 90 ° in flexion, the forearm in pronation and the dominant hand placed on the platform of the Neuroflexor device. Participants will be instructed to relax during the test session, which will consist of the passive extension of the wrist at 7 speeds, one slow (5 ° / s) and 6 rapid (50 ° / s, 100 ° / s, 150 ° / s, 200 ° / s, 236 ° / s, 280 ° / s). The total range of wrist movement will be 50 °, starting from an initial angle of 20 ° in palmar flexion up to 30 ° in extension. Before the start of the experiment, participants will do practical tests in order to become familiar with the device. Two slow and five rapid movements will be made for each speed. The different angular velocities of wrist mobilization will be randomized. Slow movements will be performed before fast movements with an interval of 10 seconds between each test. For each participant, a NC, EC and VC value in Newton will be calculated by a dedicated software. The resistance profiles will also be obtained when the device was running idle (without hand) to allow the biomechanical model to isolate the forces originating from the hand from the intrinsic forces of the device. For each movement, the corresponding surface EMG trace will have been recorded, by placing the electrodes on the skin overlying the belly of the FRC and ERC muscles. An accelerometer, fixed on the back of the hand of the limb to be examined, will be used to synchronize the electromyograph with the NeuroFlexor. The EMG activity recorded by means of surface electrodes with belly-tendon type mounting, will be amplified using the Digitimer, will then be digitized at 5 kHz using the CED, and finally it will be stored on a computer dedicated to offline analysis. EMG recordings will be made at 6 speeds, 50°/ s, 100°/ s, 150°/ s, 200 °/s, 236 °/s, 280 °/s. For each trace the following parameters will be analyzed: latency, peak-to-peak amplitude and area of the EMG response.

The Muscle in Children With Cerebral Palsy - Longitudinal Exploration of Microscopic Muscle Structure....

Cerebral PalsyMuscle Contraction1 more

Cerebral palsy (CP) is a motor impairment due to a brain malformation or a brain lesion before the age of two. Spasticity, hypertonus in flexor muscles, dyscoordination and an impaired sensorimotor control are cardinal symptoms. The brain lesion is non-progressive, but the flexor muscles of the limbs will during adolescence become relatively shorter and shorter (contracted), forcing the joints into a progressively flexed position. This will worsen the positions of already paretic and malfunctioning arms and legs. Due to bending forces across the joints, bony malformations will occur, worsening the function even further. Since about 25 years a combination treatment with intramuscular botulinum toxin injections, braces and training has had a tremendous and increasing popularity, although lasting long-term clinical advantage is not yet proven. Muscle morphology of the biceps brachii and the gastrocnemius muscles: The hypothesis is that care as usual, i.e. training and splinting sessions with botulinum toxin as adjuvant treatment, will reduce (normalize) the expression of the fast fatigable myosin heavy chain MyHC IIx and increase the expression of developmental myosin, as a possible sign of growth. As the biceps in the arm is used irregularly and voluntarily, and the gastrocnemius is activated during automated gait, the adaptations of those muscles will be different. Methods: Baseline muscle biopsies: Percutaneous biopsies are taken just before the first intramuscular botulinum toxin injection is given. The doses and the intervals for the botulinum toxin treatment will follow clinical routines. Biopsies 4-6 months, 12 months and 24 months after the first botulinum toxin injection: The exact same procedure as above will be performed, but the biopsies will be taken 2 cm distant, medial or lateral, from previous biopsy sites Significance:. More knowledge is warranted regarding the actual molecular process in the muscle leading to a contracture, and its relation to the constant communication with the injured central nervous system. This study will give answers that could result in new, early prophylactic treatment of joint movement restrictions and motor impairment in children with CP.

The Effectiveness of Repetitive Transcranial Magnetic Stimulation for Spastic Diplegia Cerebral...

Cerebral PalsySpastic

Cerebral palsy describes a group of permanent disorders of the development of movement and posture, causing activity limitation that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. Nowadays, CP is not fully curable, and physiotherapy should be used in conjunction with other interventions such as oral drugs, botulinum toxin type A, continuous pump-administered intrathecal baclofen, orthopaedic surgery and selective dorsal rhizotomy. However, several systematic reviews conclude that there is low evidence that these invasive therapies are more effective than placebo. Repetitive transcranial magnetic stimulation (rTMS) is a type of neuromodulatory technique through magnetic impulses. The effect of rTMS depends on the frequency of the emitted electromagnetic field; low frequencies (≤1 Hz) lead to an inhibition of neuronal electrical activity at the stimulation site, while high frequencies (≥3 Hz) cause neuronal depolarization. The objective of the project is to evaluate the effectiveness of a repetitive Transcranial Magnetic Stimulation (rTMS) protocol, as an adjunct treatment to neurorehabilitation to improve gross motor function and quality of life in school-age children with spastic diplegia-type infantile cerebral palsy.

Reliability of Cardiac Troponins for the Diagnosis of Myocardial Infarction in the Presence of Skeletal...

MyopathyMuscle Weakness6 more

Visits to the emergency department (ED) for chest pain are extremely common and require a safe, rapid and efficacious treatment algorithm to exclude a possible AMI. These diagnostic algorithms are partly based on an important laboratory value, which showed growing utility in the diagnostic and prognostic of many cardiovascular diseases in the last years : cardiac troponin. However, some patients with muscle disease often present with unexplained elevated high-sensitive cardiac Troponin T (hs-cTnT) levels in the absence of cardiac disease. The investigators aim at the characterization of the behaviour of this biomarker and its alternative (high-sensitive cardiac Troponin I), which will have important clinical implications on patients management.

Video Based Games Exercise Training in Individuals With Cerebral Palsy

Spastic Cerebral Palsy

Cerebral palsy (CP) is a non-progressive neurological disorder characterized by a persistent decline in sensory, cognitive or especially gross and fine motor functions during infancy or early childhood. In children with spastic CP, spasticity, muscle weakness, delay in motor development, inadequacy of gross and fine motor skills, selective motor control and functional capacity may be affected. Selective motor control (SMC) is the ability to isolate a muscle or muscle group to perform a specific movement. In children with CP, spasticity directly causes impairment of SMC, as movement patterns governed by flexor or extensor synergies are affected, which inhibits functional movements. Motor dysfunction in CP causes activity limitations and can negatively affect functional capacity. In addition, falls may increase in individuals with CP due to poor balance control, resulting in pain, injury and disability, and may cause individuals to lose confidence in their ability to perform routine activities. Increased fear of falling in individuals with CP may also lead to restriction of activities.It was discussed that the interactive computer game has possible evidence of efficacy allowing to improve gross motor function in individuals with CP. It also appears to have the potential to produce gross motor improvements in terms of strength, balance, coordination and gait for individuals with CP.As a result of our literature review, studies investigating the effect of virtual reality games on gait, balance and coordination in children with CP were observed. However, the effect of virtual reality games on selective motor control has not been sufficiently investigated. The aim of our study, which is planned to eliminate this deficiency in the literature, is to investigate the effect of video game-based exercise training, which provides higher motivation than conventional physical therapy methods, on selective motor control, fear of falling and functional capacity in individuals with CP.
