Study Description
Brief Summary:

Stroke is a major cause of disability in Canadian adults. Following a stroke, many people have difficulty walking in their home and in the community. The purpose of this study is to compare the effect of two different approaches to walking retraining in people who have had a stroke.

Individuals living in the community who have had recently had a stroke will be asked to participate in this study. Participants will be randomly assigned to one of two five week walking training programs. In one program, individuals will re-learn to walk in a variety of real-life situations. Practice sessions will encourage active problem solving by the participants. The other program will have participants practice walking on a treadmill while some of their body weight is supported by a special harness system. Participants will also be assisted by a physiotherapist to walk in a more normal manner.

Participants' will be assessed at the beginning of the study, after the 5 week training program and again, eight weeks later. The research assistant will assess their ability to walk, their confidence level and the average daily walking activity.

Primary Hypothesis: Individuals assigned to the Motor Learning Walking Program will improve their walking ability from baseline to follow up assessment significantly more than individuals assigned to the Treadmill Training Program.

The results of this study will help physiotherapists plan effective treatment programs for individuals with walking difficulties following stroke. It will also give researchers direction for future studies in the areas of walking retraining and motor skill development post-stroke.

Arms and Interventions

Arm Intervention/treatment
Experimental: Motor Learning Walking Program
Motor Learning principles based Walking Program (MLWP) Participants practice variety of real life over ground walking related activities. Order of practice, instructions, guidance and feedback are provided in a manner that facilitates cognitive engagement of learner.
Behavioral: Motor Learning Walking Program
Motor Learning principles based Walking Program (MLWP) Participants practice variety of real life over ground walking related activities. Order of practice, instructions, guidance and feedback are provided in a manner that facilitates cognitive engagement of learner. Sessions 45 minutes, 3x per week over 5 weeks for a total of 15 sessions
Other Name: Task oriented walking training
Active Comparator: Body weight supported treadmill training
Body Weight Supported Treadmill Training. Participants walk on a treadmill while partially supported with an overhead harness system. Mass repetition of the normal gait cycle is encouraged through the support of the harness, the movement of the treadmill, and the assistance of one or two trainers to position limbs and trunk.
Behavioral: Body Weight Supported Treadmill Training
Participants practice walking on a treadmill while supported with an overhead harness system. Up to 40% body weight support. Target Treadmill speed 2.0 mph. 1 or 2 Trainers (at least one Physical Therapist plus another Physical Therapist or Physiotherapy Assistant) will help guide participants leg, foot and trunk during treatment. Aim is to practice high numbers of repetition of the normal gait cycle on treadmill. Duration of sessions - 20 minutes of treadmill training within a 45 minute session ( 4 sets of 5 minutes of training with 5 minute rests). 3 sessions per week for 5 weeks. Total of 15 sessions.
Other Name: Treadmill training

Outcome Measures

Primary Outcome Measures :
  1. Self selected over ground gait speed - 5 metre walk test [ Time Frame: 8 week follow up ]

Secondary Outcome Measures :
  1. Six Minute Walk Test [ Time Frame: Post Intervention and 8 week follow up ]
  2. Self selected over ground gait speed - 5 metre walk test [ Time Frame: Post Intervention ]
  3. Balance related Self Efficacy - Activities-specific Balance Confidence Scale [ Time Frame: Post intervention and 8 week follow up ]
  4. Average Daily Step Count - StepWatch 3 Step Activity Monitor [ Time Frame: Post Intervention and 8 Week Follow up ]
  5. Dynamic Balance - Functional Balance Test [ Time Frame: Baseline, Post-intervention and 8 week Follow-up ]

    Over a 9 m track - participants are required to perform 5 balance and walking related tasks. Participants are required to 1) rise from a chair, walk 3 m, 2) step up and down an 8 inch step, walk 3 m, 3) bend down to pick up and return a 2.5 kilo weight off floor, walk 3 m to marked spot on the floor, 4) turn 180 degrees and walk 9 m back to the chair, 5. sit back down in the chair.

    Each task is scored on a 4 point scale (total score of out 20) Participants are timed on how long it takes them to perform the entire circuit.

  6. Life Space Questionnaire [ Time Frame: Baseline, Post-intervention, and at 8 week follow up ]
    Self-report measure of mobility partipation.

  7. Number of trainers required per treatment session [ Time Frame: Documented at every treatment session for both experimental and active comparison interventions. ]
  8. Patient Specific Functional Scale [ Time Frame: Baseline, Post-intervention, Follow-up (8weeks) ]

    In this measure, participants are asked to identify 3 walking related functional activities that they currently have some difficulty performing and would like to improve with treatment. For each activity, the participant rates their current ability to perform the task on a numeric rating scale of 0 to 10.

    At Post-intervention and Follow-up, participants re-rate their current ability on the same activites (without seeing their previous score).

  9. Rating of Walking functional level - Modified Functional Walking Categories [ Time Frame: Baseline, Post-intervention, Follow-up (8 weeks) ]
  10. Adverse event - Self-report of a fall(s) since baseline assessment [ Time Frame: Post Intervention Assessment ]
    Participants will be asked whether or not they have had a fall since baseline assessment. Details of the fall(s) will be recorded. Fall report based on participant recall - no other tools (e.g. diary) will be used.

  11. Adverse event - Falls (yes or no) [ Time Frame: Follow - up - 8 weeks after post-intervention assessment ]

    Participant asked to report whether or not they had a fall since Post Intervention assessment. Details of the fall will be provided.

    Based on participant recall - no other tools for falls recording will be used (ie. will not be using falls diary)

  12. Serious adverse events - ie. new stroke, myocardial infarction, overnight hospital admission, death [ Time Frame: Post-intervention, Follow up (8 weeks) ]
    Serious adverse events will be based on participant or caregiver report, and confirmed with primary care physician as appropriate.
