The aim of SWEAT² study is to further explore the effects of additional customized trunk exercises on clinical and biomechanical gait performance. Despite of the evidence demonstrating the importance of trunk control after stroke, studies about the effects of trunk rehabilitation on gait performance are inconsistent. The findings of this study might lead to new scientific insights in the importance of the trunk during gait rehabilitation in people suffering from stroke submitted to a rehabilitation hospital.
Objective: To examine the effects of additional trunk exercises on gait performance via clinical and biomechanical assessments in patients receiving inpatient rehabilitation after stroke.
Design: The design of this study is an assessor-blinded randomized controlled trial. Prior to evaluation, participants will be randomly allocated to either the experimental or control group by means of concealed envelopes. The number of patients required for this study was calculated a priori to ensure sufficient statistical power. Analysis showed that a sample size of 30 patients in each group was necessary to detect a difference (ES1) with 80 % using a two-tailed hypothesis (with significance of p=0.05).
Intervention: All patients will receive a multidisciplinary conventional stroke rehabilitation program provided by the rehabilitation staff. The control group will receive a series of cognitive exercises focusing on aspects of memory (visual, auditory, and working memory), attention (sustained attention and selective attention), and executive functioning (planning and problem-solving). The additional training of the trunk training group focuses on trunk muscle strength, coordination and selective movements. The training program will consist of task-specific movements of the upper and lower part of the trunk both in supine and sitting position on stable and unstable surfaces (physio balls). The following trunk exercises will be performed: bridging, reaching, lower/upper trunk rotations, lower/upper trunk lateral flexion, upper/lower trunk flexion, ...
Outcome measures:
Tinetti Test
Gait parameters recorded during 3D-Full body gait analysis:
Gait analysis was performed at the M²OCEAN movement analysis laboratory (Multidisciplinary Motor Centre Antwerp, University of Antwerp, Antwerp, Edegem). VICON analysis system (©Vicon Motion Systems Ltd., London, UK) which is the golden standard for 3D motion analysis. Eight infrared automated cameras (Vicon T10 cameras, 100 fps, 1 Megapixel) measured the 3D coordinates of reflective motion trackers. Two video cameras recorded the walking pattern of the participants in the sagittal and frontal plane. In addition, initial contact and toe off were measured based on the ankle trajectories of the reflective markers together with 3 AMTI type OR 6-7 force plates (1000 fps, 46x50x8 cm) and 1 AccuGait® (1000 fps) force plate recordings. Subsequently, the movement analysis lab is equipped with a 16 channel telemetric wireless electromyographic (EMG) system (Arion Zerowire) which measures muscle activity. Recordings where analysed using the Vicon Nexus 1.8.5. software. Step time parameters and gait kinematics were filtered (Butterworth filter) and further processed in Matlab® (The MathWorks, Inc., Natick, Massachusetts, U.S.A.).
Trunk Impairment Scale, Barthel Index
Follow-up. One month post intervention patients will be again subjected to clinical and biomechanical assessment to measure the sustainability of trunk exercises over time.

| The change in Tinetti Performance Oriented Mobility Assessment | Tinetti Test measures gait and balance on a 3-point ordinal scale ranging from 0 to 2. The maximum score of the total Tinetti is 28 points, whereby a maximum of 12 and 16 points can be obtained for gait and balance subscales. | week 0, week 5, and week 9 |

| The change in temporal gait parameters | The following temporal gait parameters will be investigated: stride length (m), step length (m), and step width (m). These parameters examine the difference in distance. | week 0, week 5, and week 9 |
| The change in kinematic parameters of the trunk, hip, knee, and ankle |
| Measure | Description | Time Frame |
|---|---|---|
| The change in Trunk Impairment Scale (TIS) | The TIS consists of 3 subscales of static, dynamic sitting balance and trunk coordination. TIS scores range from a minimum of 0 to a maximum of 23, subscales score up to 7, 10 and 6 points, respectively. A higher score indicates better truncal function. The static sitting balance subscale evaluates whether a person can sit independently and remain seated with legs crossed. The dynamic sitting balance subscale assesses the ability to actively shorten each side of the trunk, initiated from either the shoulder or pelvic girdle. The trunk coordination subscale tests the ability to rotate the shoulder girdle and the pelvic girdle. |
