Exploring Psychometric Properties of a New Version of the 6MWT in the Acute Stroke Population

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess inter- and intra-rater reliability of the 6MWT in people with acute stroke who require various levels of assistance with walking.

Official Title

Exploring Psychometric Properties of a New Version of the 6MWT in the Acute Stroke Population

Conditions
-----------------
Acute Stroke

Intervention / Treatment
-----------------
* Other: 6 Minutes Walking Test


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: At least 18 years old Primary diagnosis of an acute or hemorrhagic stroke Admitted into the acute or acute rehab setting and is appropriate for physical therapy services. Can ambulate with 1 person assistance and a device as needed, with no more than maximal assistance required. The patient must be able to independently advance the lower extremity forward, but can receive maximal assistance for blocking, bracing or postural control during ambulation. Can stand and/or ambulate for at least 6 minutes Exclusion Criteria: Hemodynamically unstable Unstable medical co-morbidities such as: active bleeding, recurring seizures, uncontrolled hypertension (permissive HTN orders ok) Patients with bilateral acute stroke Patients who are unable to follow 1 step commands as determined by the screening physiatrist Orthopedic co-morbidities that place a weight-bearing restriction on the lower extremities such as acute fracture, joint replacement, or other musculoskeletal injury Any other condition that would limit a patient's ability to remain in a standing position with assistance for 6 minutes at a time.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Maximal Assist group<br>Subjects with acute stroke who ambulate with Maximal assistance of 1. | Other: 6 Minutes Walking Test<br>* A walkway of 12 meters will be marked with one cone at each end. The patient will be instructed to walk back and forth as many times as possible in six minutes.<br>|
| Experimental: Moderate Assist group<br>Subjects with acute stroke who ambulate with Moderate assistance of 1. | Other: 6 Minutes Walking Test<br>* A walkway of 12 meters will be marked with one cone at each end. The patient will be instructed to walk back and forth as many times as possible in six minutes.<br>|
| Experimental: Minimal Assist group<br>Subjects with acute stroke who ambulate with Minimal assistance of 1. | Other: 6 Minutes Walking Test<br>* A walkway of 12 meters will be marked with one cone at each end. The patient will be instructed to walk back and forth as many times as possible in six minutes.<br>|
| Experimental: Supervision/Modified Independence/Independence<br>Subjects who walk without physical assistance of a helper. | Other: 6 Minutes Walking Test<br>* A walkway of 12 meters will be marked with one cone at each end. The patient will be instructed to walk back and forth as many times as possible in six minutes.<br>|
