About this study

Official title: Robot-assisted Gait Training in Patients Affected by Multiple Sclerosis: Rehabilitative Efficacy Evaluation and Comparison With Traditional Methods

In Multiple Sclerosis (MS) gait disorders represent one of the most disabling aspect that strongly influence patient quality of life. The improvement of walking ability is a primary goal for rehabilitation treatment. Current promising rehabilitative approaches for neurological disorders are based on the concept of the task-specific repetitive training. Hence, the interest in automated robotic devices that allow this typology of treatment for gait training. However, studies on the effectiveness of such methodologies are still poorly numerous in terms of functional improvement in MS patients. The aim of this controlled cross-over study is to evaluate the effectiveness of a Lokomat gait training in patients affected by Multiple Sclerosis in comparison to a ground conventional gait training.

Read the detailed description

In Multiple Sclerosis (MS), the highly variable distribution of demyelinization areas and axonal loss in the Central Nervous System can lead to very complex and unpredictable neurological deficits and clinical patterns. Gait disorders as reduced speed and stride length, gait asymmetry, increased muscular energy expenditure, balance deficit and increased risk of falling, represent one of the most disabling aspect. These motor problems strongly influence the level of independence that a person affected by MS is able to achieve, resulting in severe negative impact on quality of life. Therefore, the improvement of walking ability is a primary goal for rehabilitation treatment. Many studies demonstrated that a conventional rehabilitation treatment based on physiotherapy could be effective in increasing muscle strength and motor function, improving gait and mobility abilities, reducing fatigue and risk of falls, leading finally to an overall increase of patient autonomy. According to the most recent neurophysiological concepts based on neural plasticity, in recent years the rehabilitative approaches that seem to be more effective in improving functional performance are based on the concept of the task-specific repetitive training. As in the case of the constraint induced movement therapy (CIMT) for upper limb rehabilitation and the body weight support treadmill training (BWSTT) for the lower, the factors that appear to positively affect patient outcome are the intensity, precocity, repeatability, specificity in a training that incorporates high numbers of repetitions of task-oriented practice. Hence, the interest in automated robotic devices for gait training for MS patients has grown. With their consistent, symmetrical lower-limb trajectories, robotic devices provide many of the proprioceptive inputs that may increase cortical activation and stimulation of Central Pattern Generator (CGPs) in order to improve motor function. The use of robot-assisted-gait-training (RAGT) allows: repetition of specific and stereotyped movements in order to acquire a correct and reproducible gait pattern in conditions of balance and symmetry, early start of treatment using the activity with body weight support, safeguard of the patient with reduction of fear of falling, in order to increase the quantity and quality of the performed exercise while minimizing the intervention of a therapist. However, studies on the effectiveness of such methodologies are still poorly numerous in terms of functional improvement in patients with MS. The aim of this controlled cross-over study is to evaluate the effectiveness of a robot-driven gait orthosis (Lokomat - Hocoma, Inc., Zurich, Switzerland) gait training in patients affected by Multiple Sclerosis in comparison to a ground conventional gait training. The improvement in gait pattern, motor ability and autonomy in the functional activities of daily living will be assessed by using validated clinical and functional scales and quantitative instrumental analysis of gait kinematic parameters

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lokomat (Hocoma, Zurich, Switzerland)Device

    Patients allocated to the Experimental group performed a Robotic Assisted Gait Training by means of the Lokomat. The Lokomat is robotic device set up as an exoskeleton on the lower limbs of the patient. The system uses a dynamic body weight-support system to support he participant above a motorized treadmill synchronized with the Lokomat.

  • Conventional PhysiotherapyOther

    Patients allocated to the Control Group performed a general exercise program and a conventional gait training. The same trained therapist treated all the patients in this group and standardized the duration of each part of the treatment.

Study groups in NCT02291107
Study groupRoleWhat they receive
Experimental groupExperimentalParticipants received 25 sessions of robotically driven gait orthosis training on the Lokomat. Training occurred approximately 5 days/ week for 5 weeks, and each training session on the Lokomat lasted 30 minutes. All sessions were supervised by a trained research therapist. All participants started with 40% body weight-support and an initial treadmill speed of 1.5 km/h. Body weight-support was used primarily to facilitate an increase in walking speed; therefore, progression of training across subsequent sessions was standardized by preferentially increasing speed and then unloading body weight-support. Speed was increased to a range of 2.2 to 2.5 km/h before body weight-support was decreased. There was an active attempt to enhance the level of training at each session. After every Lokomat session, participants performed also 60 minutes of physiotherapy including general exercise program and a conventional gait training
Receives: Device: Lokomat (Hocoma, Zurich, Switzerland)
Control groupActive comparatorParticipants received 25 sessions of conventional physiotherapy. Training occurred approximately 5 days/week for 5 weeks, and each training session lasted 1 hour and half. Patients allocated to the Control Group performed the same conventional physiotherapy training of the other group: a general exercise program and a conventional gait training. The general exercise program consisted in cardiovascular warm-up exercises, muscle stretching exercises, active-assisted or active isometric and isotonic exercises for the main muscles of the trunk and limbs, relaxation exercises, coordination and static/dynamic balance exercises. The conventional gait therapy was based on the proprioceptive neuromuscular facilitation concept, training in walking on different surfaces with or without appropriate walking aids, exercises for the restoration of a correct gait pattern, implementation of residual compensatory strategies and progressive increase of walking resistance
Receives: Other: Conventional Physiotherapy
