简要总结
The overall purpose of this project is to establish the added value of training with the Hybrid Assistive Limb (HAL) exoskeleton system as part of regular rehabilitation intervention programs after stroke.
The aim of this study is to explore if HAL training when combined with conventional training in the subacute stage after stroke may accelerate the recovery of independence in walking when compared to conventional training only and if recovery is related to stroke lateralization?
详细描述
Patients will be randomized using a block randomization by a nurse, who is not otherwise involved in the study, into either 1) HAL training in addition to the conventional program or 2) evidence based conventional gait training only. The block randomization will be designed so that an even number of patients with left and right sided hemiparesis will have been included in each group at the end of the study.
Conventional training (including gait practice) will be performed according to current best practice (approximately 30-60 min per day, 5 days per week) and may include stepping, weight shifting, over ground walking as well as the use of a treadmill with/without body weight support (BWS).
HAL training will be performed 4 days a week for 4 weeks (i.e. 16 sessions) with the single-leg version of HAL, primarily by use of the voluntary HAL-mode (CVC mode), on a treadmill with BWS. The therapist(s) educated in the HAL method will optimize the HAL settings for each individual during each session, in order to obtain a symmetrical gait pattern as close to normal gait as possible.
Outcomes The primary outcome will be changes in the FAC-score during the intervention. FAC assesses activity in terms of independence in walking on a six-grade-ordinal-scale ranging from non-functional walking to independent walking outside. During the intervention assessments with the FAC will be performed weekly by the patients' physiotherapist responsible for conventional rehabilitation. This therapist will otherwise not be involved in the study.
Secondary outcomes include aspects of body functions assessed by use of the NIH Stroke Scale, Albert's test, Fugl-Meyer Assessment(FMA-LE) and the Modified Ashworth Scale for the lower extremities.

入选标准
- •Patients aged 18-67 will be recruited from 1) the University Department of Rehabilitation Medicine at Danderyd Hospital in Stockholm and 2) Sahlgrenska University Hospital in Gothenburg, where they are admitted to inpatient rehabilitation early after stroke. Inclusion criteria will be: less than 8 weeks since stroke onset; inability to walk independently due to lower extremity paresis (i.e. Functional Ambulation Categories (FAC) score 0-1), able to sit on a bench with or-without supervision at least 5 minutes; sufficient postural control to allow upright position in standing with aids and/or manual support; ability to understand training instructions as well as written and oral study information and to express informed consent; body size compatible with the HAL suit.
排除标准
- •include: contracture restricting gait movements at any lower limb joint; cardiovascular or other somatic condition incompatible with intensive gait training; and severe, contagious infections.
