Plain English summary of protocol
Background and study aims:
Increased resistance when a joint is moved slowly (passive ankle joint stiffness), increased resistance with exaggerated muscle activity when the muscle is stretched at high velocity (spasticity) and decreased joint mobility (contractures) are common symptoms in patients with a brain injury. These symptoms may lead to increased joint stiffness, abnormal joint positions, reduced physical performance and pain. Currently, these symptoms are treated with physiotherapy and antispastic medication. Some challenges, however, exist for the correct diagnosis, choice of treatment strategies, and measurement of the outcome of such strategies. Current scoring scales are, however, unable to adequately measure and discriminate between the different components of reduced joint mobility. Furthermore, it is not clear whether current treatment strategies prevent stiffness, spasticity or contractures. The aim of this study is to make a biomechanical evaluation of the occurrence of spasticity, stiffness and contractures in patients with severe acquired brain injuries.
Who can participate?
Adults (age 18 or older) with severe acquired brain injuries and paresis or paralysis in the lower extremities.
Healthy adults (age 18 or older) with no history of neurological disease or fractures of the lower extremities.
What does the study involve?
Participants are recruited after admission to the department. Participants are tested for their muscle tone and spasticity and provide a blood sample. Participants are also given a portable device to wear on their foot and are asked to performed stretches in both of their left and right ankles. This assesses their ankle joint function. Participants are monitored throughout their hospitalisation and have a follow-up measurement one year after the injury date.
What are the possible benefits and risks of participating?
There are no notable benefits or risks of participating.
Where is the study run from?
Department of Neurorehabilitation, Traumatic Brain Injury, Rigshospitalet (Denmark)

| Scientific title | Occurrence of passive ankle joint stiffness, spasticity and contractures in patients with severe aquired brain injury |
| Study objectives | With biomechanical measurements of muscle function it is possible to evaluate muscle function objectively and distinguish the different components of muscle tonus. |
| Ethics approval(s) | Ethics Committee of Copenhagen Denmark, 07/01/2014, ref: H-2-2014-058 |
| Health condition(s) or problem(s) studied | Severe aquired brain injury |
| Intervention | Both healthy adults and adults with severe acquired brain injury are included in this study. Participants are allocated to either the group of patients, if they were diagnosed with a severe acquired brain injury and admitted to the neurorehabilitation ward, or to the group of healthy controls. The group of healthy controls are recruited. Group 1 Patients with severe acquired brain injury: Participants in this group attend one test session every week during hospitalization after admission to the neurorehabilitation ward. Furthermore they attend one test session one year after injury date. The total duration of each session is approximately one hour. The test session consists of a subjective, clinical tool to measure spasticity, the Modified Ashworth Scale (MAS) and an objective evalutation of passive and reflex mediated stiffness in the ankle joint plantar flexors by a hand-held device attached under the foot. The device contains a dynamometer, electromyography, accelerometer and a gyroscope. The patient is lying supine in bed. An experienced clinician performs slow stretches of the ankle joint from a plantar flexed position. Afterwards, fast stretches above the stretch reflex threshold are applied. One test session consists of five slow stretches and five fast stretches of each ankle joint. The purpose of this study is to evaluate the development of contractures, spasticity and ankle joint stiffness in patients admitted to neurorehabilitation. Patients that are included in the study receive the same physiotherapy and medical treatment as other patients at the department. Group 2 Healthy participants: Each participant undergo one test session with a duration of approximately one hour. The test procedure is the same as for patients except that healthy participants are not having a subjective clinical evalutation of their muscle tonus (The MAS test). The group of patients with severe acquired brain injury attended a follow-up test session one year after their injury date. |

| Primary outcome measure | 1. Passive ankle joint stiffness during both slow and fast dorsiflexions is measured using a biomechanical, hand-held device. Patients with severe acquired brain injuries are measured once every week during hospitalization. One year after their injury date, patients will attend one test session. Healthy controls are measured once. 2. Quantification of the occurrence of muscle contractures from measurements of range of motion is measured using “a hand-held device containing a gyroscope”. Measurements are taken once every week during hospitalization and 1 year after the injury. Healthy controls are measured once during one test session. 3. Quantification of the occurrence of spasticity during hospitalization and one year after the injury is measured using the hand-held device and is compared to the clinical measure of spasticity using the MAS test |
| Secondary outcome measures | 1. Changes in collagen types, actin and myosin involved in construction of muscle tissue “are” measured from a blood sample taken from the patients at the first test session during hospitalization and in the beginning of the test session for the healthy controls. Blood samples are analyzed with the Next Generation Sequencing method. 2. Clinical data is measured during hospitalization: 2.1. Functional independence measure (FIM™) 2.2. Early Functional Abilities (EFA) 2.3. Glasgow Come Scale (GCS) 2.4. Glasgow Outcome Scale-Extended (GOS-E) 3. The amount of physiotherapy and any use spasticity reducing medication “are registered in a database by the clinicians with information on date, type and amount of treatment. Information relevant to the study will then be extracted from the database. |
