Title: Gait Pattern Analysis and Feasibility of Gait Training With a Newly Developed Walking Assist Robot in Stroke Patients and Elderly Adults
Brief Summary: The purpose of this study was to investigate the effects of the new wearable hip assist robot developed by Samsung Advanced Institute of Technology (Samsung Electronics Co, Ltd., Korea) to gait rehabilitation in elderly adults and stroke patients.


Options:
A: Inclusion Criteria:

* Patients with infratentorial stroke
* Cognitively intact enough to understand and follow the instructions from the investigator

Exclusion Criteria:

* chronic neurological pathology
* orthopedic injuries
* femur lengths of less than 34cm
* severely limited range of lower extremity joint motion
* medical instability
B: Inclusion Criteria:

* Elderly adults

  1. Age: between 65 and 84 years
  2. elderly adults who had no neurological or musculoskeletal abnormalities affecting gait
  3. Ability to walk at least 10m regardless of assist devices
  4. High levels of physical performance (SPPB \> 7)
  5. Subject is willing to be randomized to the control group or the treatment group
* Stroke

  1. Age: between 50 and 84 years
  2. ≥ 3 months post stroke
  3. Ability to walk at least 10m regardless of assist devices
  4. Adequate gait function (FAC \> 3)
  5. Physician approval for patient participation
  6. Subject is willing to be randomized to the control group or the treatment group

Exclusion Criteria:

* Elderly adults

  1. History of any diseases (eg. lower extremity orthopedic diseases, neurologic disorders, cardiovascular disease, heart failure, uncontrolled hypertension that affect walking capacity, efficiency, and endurance)
  2. Severe visual impairment or dizziness that increases the risk of falls
* Stroke

  1. Serious cardiac conditions (hospitalization for myocardial infarction or heart surgery within 3 months, history of congestive heart failure, documented serious and unstable cardiac arrhythmias, hypertrophic cardiomyopathy, severe aortic stenosis, angina or dyspnea at rest or during activities of daily living)
  2. Advanced liver, kidney, cardiac, or pulmonary disease
  3. History of concussion in last 6 months
  4. History of unexplained, recurring headaches, epilepsy/seizures/skull fractures or skull deficits
  5. Preexisting neurological disorders such as Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), dementia
C: Inclusion Criteria:

(i) age ≥55 years; (ii) a first-ever ischemic supra-tentorial stroke (confirmed by MRI scan) at least 6 months before their enrollment; (iii) an unilateral hemiparesis, with a Muscle Research Council -MCR- score ≤3; (iv) ability to follow verbal instructions, with a Mini-Mental State Examination (MMSE) \>24; (v) a Modified Ashworth Scale (MAS) score ≤2; (vi) no severe bone or joint disease; and (vii) no history of concomitant neurodegenerative diseases or brain surgery.

Exclusion Criteria:

-
D: Inclusion Criteria:

* Have been admitted to a hospital unit for stroke treatment
* Stroke within last 3 months
* One-sided hemiparesis
* 19 years or older
* Requires 2-person assist to walk
* Able to communicate and follow instructions

Exclusion Criteria:

* Stroke of non-vascular origin (e.g. tumour, infection)
* Significant musculoskeletal or other neurological condition
* Co-morbidities that would preclude activity
* Pregnant
* Unable to walk prior to stroke
* \<60 inches or \>74 inches in height
* \>220 pounds in weight
* Joint contractures or spasticity that would limit safe use of the Ekso exoskeleton
