Studies Tong et al. 2006 and Ng et al. 2008, Morone et al. 2011 and Morone et al. 2012, and Ada et al. 2010 and Dean 2010 et al. are dependent as they investigated the same dataset. MQ: methodological quality as assessed with the PEDro scale (…/10); SD: standard deviation; MI: Motricity Index subscale for the lower limb; RAGT: robot-assisted gait training; BWSTT: body-weight supported treadmill training; EE: end-effector device; Exo: exoskeleton device; n/r, not reported. Descriptive analysis of the intervention 81 All participants were provided with repetitive gait training or conventional therapy as an add-on to usual care, depending on the group to which they were al- located. Usual care included 25–60 min of physioth- erapy daily. To allow non-ambulant patients in the experimental group to repetitively practice gait, various forms of manual and (electro-) mechanical assistance were pro- vided. In all but 1 (46) included studies, participants’ body weight and trunk was (partly) supported by an overhead harness system, while stationary practicing walking on a moving treadmill or footplates. In a single study, the trunk is not suspended in a harness, but a robot device supports the legs and trunk for stance stability to allow full weight-bearing by the patient (46). Body weight supported training can be divided into BWSTT and RAGT depending on the kind of assistance in locomotion provided. During BWSTT, patients train on a treadmill while therapists manually assist stance stability, swing initiation and forward progression of the paretic leg in a cyclical motion (36, 37, 41, 47). RAGT involves a similar stationary set-up while patients are not manually assisted by the therapist(s), but with an electromecha- nical device, i.e. a robot. Two different kinds of robots can be classified based on the motion they apply to the patient (see Fig. 2): • The Gait Trainer (35, 39, 40, 42–44, 48) is an end- effector device, meaning that motion is applied to the feet of the patient only by 2 footplates whose driven movement simulates stance- and swing-phase of a symmetrical gait pattern. This kind of assistance differs from treadmill-based training, as during the whole gait-cycle the feet are in contact with the Repetitive Gait Training Manual assistance Electromechanical assistance Robot-assisted Gait Training Body-Weight Supported Treadmill Training Body-weight support Body-weight support Body-weight support Exoskeleton End-effector Hip drive Knee drive Footplate Treadmill Drive Treadmill Fig. 2.
