Study type | Interventional |
To date, no studies seems to compare conventional gait rehabilitation program with end-effector RAGT in subacute stroke patients by analysing the variations of gait kinematics beyond clinical multi prospective outcomes. The aim of this pilot study is to evaluate the efficacy of end-effector RAGT in subacute stroke patients in terms of clinical outcomes and gait kinematics, comparing them with conventional gait rehabilitation program.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Gait Analysis | Kinematic and kinetic gait parameters will be calculated from data acquired with a motion capture system (SMART-DX; BTSBioengneering, Italy). | Session 1 (baseline), and Session 20 (week 7) | |
Other | Postural Analysis | Posturographic parameters will be obtained from the analysis of the center of pressure (COP) trajectories measured by force platforms during standing in both open and closed eyes conditions. | Session 1 (baseline), and Session 20 (week 7) | |
Primary | Change in Six-Minute Walking Test (6MWT) | The 6MWT measures the distance a subject covers during an indoor gait on a flat, hard surface in 6 minutes, using assistive devices, as necessary. The test is a reliable and valid evaluation of functional exercise capacity and is used as a sub-maximal test of aerobic capacity and endurance. The minimal detectable change in distance for people with sub-acute stroke is 60.98 meters. The 6MWT is a patient self-paced walk test and assesses the level of functional capacity. Patients are allowed to stop and rest during the test. However, the timer does not stop. If the patient is unable to complete the test, the time is stopped at that moment. The missing time and the reason of the stop are recorded. This test will be administered while wearing a pulse oximeter to monitor heart rate and oxygen saturation, also integrated with Borg scale to assess dyspnea. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Fugl-Meyer Assessment (FMA) scale | The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment. The scale is comprised of five domains and there are 155 items in total:
Motor functioning (the score ranges from 0 (hemiplegia) to 100 points (normal motor performance). Divided into 66 points for upper extremity and 34 points for the lower extremity. Sensory functioning (from 0 to 24 points) Balance (from 0 to 14) Joint range of motion (from 0 to 44) Joint pain (from 0 to 44 ) Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226. |
Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Motricity Index (MI) | The MI aims to evaluate lower limb motor impairment after stroke, administrated on both sides.
Items to assess the lower limbs are 3, scoring from 0 to 33 each: (1) ankle dorsiflexion with foot in a plantar flexed position (2) knee extension with the foot unsupported and the knee at 90° (3) hip flexion with the hip at 90° moving the knee as close as possible to the chin. (no movement: 0, palpable flicker but no movement: 9, movement but not against gravity :14, movement against gravity movement against gravity: 19, movement against resistance: 25, normal:33) |
Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Modified Ashworth Scale (MAS) | The MAS is a 6 point ordinal scale used for grading hypertonia in individuals with neurological diagnoses. A score of 0 on the scale indicates no increase in tone while a score of 4 indicates rigidity. Tone is scored by passively moving the individual's limb and assessing the amount of resistance to movement felt by the examiner. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Tinetti Scale Balance (TIN-B) | Scales to measure activity ICF domain. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Tinetti Walking (TIN-W) | Scales to measure activity ICF domain. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Functional Ambulation Classification (FAC) | Functional Ambulation Classification is a functional walking test that evaluates ambulation ability. This 6-point scale assesses ambulation status by determining how much human support the patient requires when walking, regardless of whether or not they use a personal assistive device. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Trunk Control Test (TCT) | The TCT assesses the motor impairment in stroke patients and it's correlated with eventual walking ability. Testing is done with the patient lying on a bed: (1) roll to weak side. (2) roll to strong side. (3) balance in sitting position on the edge of the bed with the feet off the ground for at least 30. (4) sit up from lying down. Total score: 0-100 | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in 10 Meter Walk Test (10MWT) | This test will assess the patient's speed during gait. Patients will be asked to walk at their preferred maximum and safe speed. Patients will be positioned 1 meter before the start line and instructed to walk 10 meters, and pass the end line approximately 1 meter after. The distance before and after the course are meant to minimize the effect of acceleration and deceleration. Time will be measured using a stopwatch and recorded to the one hundredth of a second (ex: 2.15 s). The test will be recorded 3 times, with adequate rests between them. The average of the 3 times should be recorded. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Time Up And Go (TUG) | The Time Up And Go is a test used to assess mobility, balance, and walking in people with balance impairments. The subject must stand up from a chair (which should not be leant against a wall), walk a distance of 3 meters, turn around, walk back to the chair and sit down - all performed as quickly and as safely as possible. Time will be measured using a chronometer. | Session 1 (baseline), and Session 20 (week 7) | |
Secondary | Change in Walking Handicap Scale (WHS) | The Walking Handicap Scale is a classification of 6 functional walking categories, considered as a participation category of the ICF because of its 3 items referred to community ambulation. The score ranges from 1 to 6, and do higher values represent a better outcome. | Session 1 (baseline), and Session 20 (week 7) |
