Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Overall aim is to evaluate HAL for gait training early after stroke and the effect of HAL on short- and long-term functioning, disability and health compared to conventional gait training as part of an inpatient rehabilitation program early after stroke.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To compare outcome after 4 weeks of gait training with HAL vs. 4 weeks of conventional gait training as part of a regular inpatient rehabilitation program for hemiparetic patients with severely limited mobility early after stroke.

Study design: Randomized, controlled study with blinded outcome assessment.

Conventional gait training is individualized and performed according to current practice (approximately 30-60 minutes/session, 5 days a week) and may include standing, weight shifting, stepping, over ground walking with assistance and/or assistant devices as well as the use of a treadmill and body weight support. Conventional gait training is offered to both study groups.

Training with HAL is performed in 1 session per day, 4 days per week during 4 weeks. Time for each session is individualised but does not exceed 60 minutes/session (effective time). Training with HAL is performed in combination with body-weight support system and on a treadmill. The training program is performed by 2 physiotherapists, who have been trained in the HAL method.

Study Group

Intervention: Hybrid Assistive Limb (HAL); gait training in combination with conventional training. Training with the exosceleton Hybrid Assistive Limb (HAL) is performed in 1 session per day, 4 days per week during 4 weeks. Time for each session is individualised but does not exceed 60 minutes/session (effective time). Training with HAL is performed in combination with body-weight support system and on a treadmill. The training program is performed by 2 physiotherapists, who have been trained in the HAL method.
