The Stroke Foundation’s clinical guidelines for rehabilitation contain a guideline for improving walking after stroke that is a STRONG recommendation:
Stroke survivors with difficulty walking should be given the opportunity to undertake tailored repetitive practice of walking (or components of walking) as much as possible. (French et al. 2016 [173])
This StrokeEd Blog will share our interpretation of this guideline recommendation. Three points will be discussed:
- “Tailored” repetitive practice of walking
- “Components” of walking
- “As much as possible”
Repetitive practice of walking is evident – but what is meant by the term “tailored”? We interpret this to mean practice of walking that is tailored to eac h stroke survivor’s specific problems. Some examples of common problems, and training strategies to address those problems, could include:
Problem = decreased stance time on affected leg
Training strategies=
- Walking with auditory cueing of cadence (Nascimento et al 2015)
- Note- see StrokeEd Blog on cueing of cadence
- Visual cueing of cadence
- Walking with visual cues for increased step length/symmetrical steps
Problem = decreased hip/knee/ankle flexion to clear the ground in swing
Training strategies =
- Walking with an obstacle course
- Walking on treadmill with increasing speeds and inclines
Problem = walking with knee hyperextension
Training strategies =
- If stroke survivor can prevent knee hyperextension, walking with feedback device to indicate knee hyperextension
- If stroke survivor cannot prevent knee hyperextension – strategies to reduce hyperextension (Note: I don’t know of any evidence for these) can include;
- applying rigid tape to back of knee while the knee is flexed
- applying a firm bandage in figure of 8 while knee is in 90 degrees flexion
Problem = slow walking with decreased stance time on affected leg
Training strategies that target a component:
- Stepping intact leg forward and back with visual cues for distance and base of support and for hip extension if necessary
- Stepping intact leg on/off a block with cues to maintain extension of affected leg if necessary ie standing with back to wall
Problem = decreased hip/knee/ankle flexion to clear the ground in swing
Training strategies that target a component:
- Stepping affected leg forward and backward with visual cues for distance
- To encourage more ankle dorsiflexion
- verbal cueing to achieve heel strike will focus attention on ankle dorsiflexion
- To decrease hip circumduction
- place block to side of affected leg, stroke survivor needs to try to avoid the block
- Stepping affected leg on and off a block
- To encourage more ankle dorsiflexion
- place the block immediately in front of affected foot as foot will catch edge of block if no dorsiflexion
- To encourage more hip/knee flexion
- place a higher block in front of affected leg
- To encourage more ankle dorsiflexion
- To encourage more ankle dorsiflexion
Problem = walking with knee hyperextension
Training strategies that target a component:
- Stepping intact leg forward and back with visual cues for distance
- To encourage shank to move forward over foot (this will reduce knee hyperextension)
- use verbal instruction “bring knee forward over your foot”
- use tactile cue, knee needs to move forward to touch cue
- To encourage shank to move forward over foot (this will reduce knee hyperextension)
While we do not know the dosages of practice needed to change a person’s performance, there is a dose-response relationship (ie more practice = better outcomes). To provide opportunities for people to do as much practice as possible, the following strategies can be used:
- Semi-supervised practice (ie circuit classes, workstations set-up in gym environment for safe practice)
- Independent practice
