Interactive Exoskeleton Robot for Walking - Knee Joint

15. september 2017 opdateret af: Raymond KY Tong, Chinese University of Hong Kong
An exoskeleton robotic knee system for stroke rehabilitation is proposed in this study. This robotic system has been developed to facilitate functional motor recovery by practices walking with a one joint motor powered exoskeleton to reduce the muscle weakness in the shank and reduce the hyperextension in the knee joint. The robotic knee system is able to sense the gait pattern from the stroke patients and assist the walking and control the knee angle. The clinical trial will use repeated measurements to evaluate the effectiveness of the robotic knee system in gait rehabilitation post stroke.

Beskrivelse

Inclusion Criteria:

  1. Ischemic or hemorrphagic stroke with drop foot problem.
  2. Sufficient cognition to follow simple instructions and to understand the content and purpose of the study. (Mini-Mental State Examination > 20)
  3. Capable of standing and walking independently for an extended period of time. (Functional Ambulation Category > 3, Berg Balance Scale > 40)

Exclusion Criteria:

  1. Any medical or psychological dysfunctions that would affect their ability to comply with test study protocol, such as lower back pain, neuralgia, rotational vertigo, muscloskeletal disorders, injuries, and pregnancy.
  2. Any severe contractures in hip, knee, or ankle joint that would preclude passive range of motion in the lower extremity.
  3. Participation in any therapeutic treatment ("outside therapy") performed with the lower extremity during the planned study, including the baseline and the followup.

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Functional Ambulation Category
Tidsramme: 3-month followup

Patients can be rated on the following categories:

0: Patient cannot walk, or needs help from 2 or more persons

  1. Patients needs firm continuous support from 1 person who helps carrying weight and with balance
  2. Patient needs continuous or intermittent support of one person to help with balance and coordination.
  3. Patient requires verbal supervision or stand-by help from one person without physical contact
  4. Patient can walk independently on level ground, but requires help on stairs, slopes or uneven surfaces
  5. Patient can walk independently anywhere
3-month followup
6-minute Walk Test
Tidsramme: 3-month followup
Walk as far a distance as possible over 6 minutes with their preferred speed; assistive devices can be used but kept consistent from test to test Individual should be able to ambulate without physical assistance.
3-month followup

Timed 10-meter Walk Test
Tidsramme: 3-month followup
The individual is instructed to walk a set distance (10 meters). Time is measured while the individual walks the set distance (often the individual is given space to accelerate to his/her preferred walking speed (this distance is not included when determining speed). The distance covered is divided by the time it took the individual to walk that distance.
3-month followup
Modified Ashworth Scale
Tidsramme: 3-month followup
Tests resistance to passive movement about a joint with varying degrees of velocity; scores range from 0-4, with 6 choices
3-month followup
Berg Balance Scale
Tidsramme: 3-month followup
Static and dynamic activities of varying difficulty are performed Item-level scores range from 0-4, determined by ability to perform the assessed activity Item scores are summed Maximum score = 56
