“…The speed of the treadmill can be adjusted from 0 km/h to approximately 3 km/h and body weight support from 0% to 100%. 6,7,12 At the beginning of the treatment period, 30% of the body weight of each subject was supported.…”

“…5 The Lokomat is adjustable in force, body weight support, and speed so that even severely handicapped patients can exercise in an environment delivering as much challenge as can be handled. 6,7 Although the Lokomat provides a simplified environment for postural control, propulsion, coordination, and stepping, walking speed can be exercised in a way that is much closer to the principles of motor learning concepts that progress from the simple to the complex, from the easy to the difficult, while all movements remain as close as possible to the final desired movement. Besides task specificity, the number of repetitions of tasks and training intensity are basic aspects of established principles in locomotor training.…”

Background and Purpose-The success of gait rehabilitation after stroke depends on active walking exercises. However, the disabling after-effects of stroke often make such exercises impossible at the onset of therapy. To facilitate treadmill training of paraparetic patients, a robot-driven gait orthosis (Lokomat) was developed. We investigated the effects of the Lokomat when used with hemiparetic patients. Methods-The authors conducted a randomized, controlled pilot study of 30 acute stroke survivors. The treatment group received 30 minutes of robotic training daily and the control group 30 minutes of conventional physiotherapy daily in addition to 30 minutes of conventional physiotherapy for each group. Outcome measures were independence of gait, gait speed, gait parameters, and body tissue composition. Results-After 4 weeks of therapy, the walking ability of the Lokomat group and the control group expressed as the functional ambulation classification was significantly improved. The functional ambulation category (medianϮ interquartile range) was at baseline 0Ϯ0 in control and 0Ϯ1 in the therapy group and increased after therapy to 1Ϯ3 in both groups significantly (Pϭ0.01). There was no significant difference in gain of these parameters between the groups. The Lokomat group had a significantly longer single stance phase (sec; meanϮSEM) on the paretic leg when walking on the floor. At baseline, it was 0.19Ϯ0.17 and after therapy 0.49Ϯ0.07 (Pϭ0.014). The control group had increased their body weight approximately 1.33Ϯ1.40 kg (meanϮSEM; Pϭ0.046), mostly as fat mass, whereas the Lokomat group had lost fat mass approximately Ϫ2.9Ϯ1.0 kg (meanϮSEM; Pϭ0.016) and increased their muscle mass approximately 3.36Ϯ1.4 kg (meanϮ SEM; Pϭ0.031). Conclusions-This pilot study indicates that Lokomat therapy is a promising intervention for gait rehabilitation. Although there was no difference between groups in gain of functional scores, the Lokomat group showed an advantage of robotic training over conventional physiotherapy in improvement of gait abnormality and body tissue composition.

Context: Spinal cord injury (SCI) affects more than 2.5 million people worldwide, often leading to severe disability. Thus, a proper management of individuals with SCI is required either in the acute or in the postacute rehabilitative phase. Findings: A 31-year-old man, affected by chronic SCI, underwent two different intensive rehabilitation treatments, including either LokomatPro or a paired LokomatPro-rTMS training. We evaluated the clinical, kinetic, and electrophysiological parameters before and after each training session. In particular, the intensive robotic training was articulated in a total of 40 one-hour training sessions (i.e. 5 times a week for 8 weeks), whereas the rTMS sessions were delivered 3 days per week for 3 consecutive weeks, just before the LokomatPro session. Only at the end of the experimental treatment, we observed an important improvement in nearly all parameters we investigated. Clinical relevance: The combined LokomatPro-rTMS rehabilitation may be a valuable approach in improving the motor function in patients affected by SCI, even in the chronic phase.

“…This finding was promising, but no significant group difference was found for any other measure [11]. One gait robot [12] (Lokomat, Hocoma Inc; Chicago, Illinois) could provide assisted or passively induced swing-phase gait movements that were close to normal early after injury or stroke. One disadvantage of a gait robot is that passive movement practice is not optimal for motor learning.…”

Abstract-After stroke rehabilitation, many survivors of stroke exhibit persistent gait deficits. In previous work, we demonstrated significant gains in gait kinematics for survivors of chronic stroke using multichannel functional electrical stimulation with intramuscular electrodes (FES-IM). For this study, we tested the feasibility of combining FES-IM and gait robot technologies for treating persistent gait deficits after stroke. Six subjects, >/= 6 months after stroke, received 30-minute intervention sessions of combined FES-IM and gait robotics 4 days a week for 12 weeks. Feasibility was assessed according to three factors: (1) performance of the interface of the two technologies during intervention sessions, (2) clinicians' success in using two technologies simultaneously, and (3) subject satisfaction. FES-IM system hardware and software design features combined with the gait robot technology proved feasible to use. Each technology alone provided unique advantages and disadvantages of gait practice characteristics. Because of the unique advantages and disadvantages of each technology, gait deficits need to be accurately identified and a judicious treatment plan properly targeted before FES-IM, a gait robot, or both combined are selected.
