In this last part of the stroke article series, management towards continuous recovery will be explored specifically the post-stroke rehabilitation. Click here if you would like to reference Part 1 of the stroke rehabilitation series, or Part 2 of the series.
Continuous Interventions for Recovery
The role of exercises and rehabilitation strategies is to regain control of movement, work on impairments, and promote independence for survivors of stroke. Improving the function of the limbs and regaining control with movement is with an emphasis on the more involved side is achieved not only through exercises alone, but by adding specific re-education and motor learning strategies to train the body once again to move. To make the exercises for meaningful, functional, task-specific activities are incorporated into the exercise plan.
Additionally, progressive exercises are also included in the recovery plan to further address weakness, decreased flexibility, decreased mobility, decreased endurance, and other bodily functions.
Even if functional, task-specific exercises are the mainstay of rehabilitation, management for other impairments is also incorporated in the treatment plan, especially with stroke syndromes demonstrating other manifestations hindering recovery.
Below we have shared some examples of tasks and exercises that are recommended to help in latter stage recovery from stroke.
Exercises for Joint Mobility and Flexibility of Post-stroke Rehabilitation
A. Upper Body
1. Arm Cradling
Your stronger arm cradles and lifts the weak arm to 90-degree shoulder flexion. Then, assist the weak arm into moving up, then side to side. Active trunk rotation is combined with arm movement. Start post-this post-stroke rehabilitation exercise with 1 set of 10 repetitions in each direction (shoulder flexion and side-to-side).
2. Table-Top Polishing
Place your arms on the top of the table, with your shoulders protracted and elbows extended. Place a towel under your both hands. Your less affected hand moves the affected hand by pushing the towel forward, side-to-side, and in circles. Trunk movements and range of motion are optimized by placing the chair slightly back from the table. Start with 5 repetitions of each movement pattern (forward, side-to-side, circles).
3. Crawling Stretch
Start in a crawling position on your hands and knees. Gently shift your hips back until you feel a stretch in your inner arms and hold this position for 15-30 seconds. Start with 1 set of 5 repetitions.
4. Wrist Stretching
While keeping your affected elbow, use your strong hand to flex your affected wrist back and forth until you feel a stretch. Hold each stretch for 15-30 seconds. Start with 1 set of 5 repetitions in each direction.
B. Lower Leg
1. Seated Hip Flexor Stretch
Sit on a sturdy chair with a backrest. Hold onto the back of the chair and carefully turn your body so that only one half of your seat is on the chair. While sitting tall, extend one leg back as far as you can comfortably. You want to feel a stretch in the front of your back leg. Hold this position for 15-30 seconds. Carefully return to the starting position and repeat the exercise on the opposite side. Start this with 1 set of 5 repetitions on each side to improve your post-stroke rehabilitation.
If you find this exercise too challenging, ask a caregiver to assist you.
Alternative Exercise: Supine Hip Flexor Stretch
Using a high bench or bed, lay on your back with your affected hip’s side along the edge. Let your target leg drop off the edge of the bed with your knee bent. Meanwhile, pull your knee towards your chest. You should feel this stretch along the front of your hip and through the quadriceps. Hold this stretch for 15-30 seconds. Start with 1 set of 5 repetitions on each side.
2. Seated Hamstring Stretch
Sit on the bed with one leg extended. Sit up tall and pivot at the hips as you reach towards your foot (don’t bend your back) and hold this position for 15-30 seconds. Start with 1 set of 5 repetitions on each side.
Alternative Exercise: Seated Hamstring Stretch on a Chair
You can also do this exercise while seated on a sturdy chair. Be sure to bend through the hips and not the low back.
3. Calf Stretch
While seated on a sturdy chair, place the ball of your foot on a step or a raised surface and let your heel drop to the floor. Keep your knee bent and lean slightly on your knee to provide some pressure on the leg to stretch the calf. Hold this stretch for 15-30 seconds. Start with 1 set of 5 repetitions on each side.
4. Seated Piriformis Stretch
While sitting in a chair, cross your affected ankle over your opposite knee. Gently lean forward until a stretch is felt along the crossed leg. Throughout the stretch, try to keep your back as flat as possible and lean forward from the hips. Hold this stretch for 15-30 seconds, then relax. Start with 1 set of 5 repetitions on each side.
Exercises for Strength of a Post-stroke Rehabilitation
A. Upper Body
1. Shoulder Flexion
Clasp your hands together. If you can, hold a weight between your clasped hands (food cans and water bottles can be used as well). Keeping your arms straight. Raise your arms overhead, then lower your arms back down to the starting position. Start with 1 set of 10 repetitions on each side.
2. Lateral Arm Raise
While seated, hold the weight in your affected hand. Keeping your arm straight, lift your arm out to the side to shoulder-height, then lower your arm to the starting position. Start with 1 set of 10 repetitions on each side.
Alternative Exercise: Wand Exercise in Shoulder Abduction
Use a cane, an umbrella, a ski pole, or a broom for this exercise. Hold each end of the stick, then push your affected arm upwards until you reach shoulder level. Lower your arm to the starting position and repeat the movement. Start with 1 set of 10 repetitions on each side.
3. Shoulder External Rotation Exercise
Use resistant tubing or light dumbbells for this exercise. Start with your elbows bent at 90-degree angles with your upper arms aligned with your upper body.

3 Side to Side Reaching in Sitting
Sit on the edge of your bed or on a chair. Place your hands at your sides for support. Reach across your body at shoulder height with one arm. Return to the starting position and repeat the movement on the opposite side. If your weak arm buckles or the hand slides, have helper support your weak arm at the wrist and just above the elbow. Start with 1 set of 10 repetitions on each side.
4. Weight Shifting in Standing
Place both hands on the surface of a counter or table as postural support. Place most of your weight on your hands with your arms extended. Shift your weight to your weak arm and hold this position for 6-10 seconds. Relax and repeat the movement. Start with 1 set of 10 repetitions.
5. Supported Single-Leg Standing
Place both hands on the back of a chair or countertop for balance. Slowly lift your strong leg until you are balanced on your weak leg and hold this position for 6 seconds. Slowly lower your leg back down to the starting position and repeat the movement on the opposite side. Start with 1 set of 5 repetitions on each side.
If you find your weak leg buckles, have a caregiver assist you by stabilizing the knee of your weak leg as you do the exercise.
Functional Exercises of Post-stroke Rehabilitation
1. Ball Squeeze/Towel Grip Exercise
Hold a small ball or a rolled towel in your palm. Squeeze it as hard as you can without causing your hand pain and hold this position for 3-5 seconds. Release the pressure and repeat the movement. Work up to 10 – 12 repetitions on each hand.
2. Seated Woodchops
Start in a seated position on a sturdy chair with your hands clasped together. Raise your arms over one shoulder, then diagonally lower your arms to your opposite foot. Repeat the movement. Start with 5-10 repetitions on each side.
3. Sit to Stand
Begin in a seated position on a firm, stable surface, such as a chair or your bed. Keep your feet hip-width distance apart. Focus on maintaining equal weight across your affected and unaffected leg. Clasp your hands together and raise to a standing position. Keep your head looking forward and your chest out. Slowly lower your seat down to the chair and repeat the movement. Start with 1 set of 15 – 20 repetitions.
4. Stepping Exercise: Forward and Backward
Stand with one hand on the back of a chair or table for support. Stand with your feet about hip distance apart with your toes pointing forward. Shift your weight onto your affected leg, then step forward with your strong leg. Step back to the starting position. This time, shift your weight again to your affected leg and step back with your unaffected leg. Step back to the starting position and repeat the sequence of movements. Start with 10 repetitions on each side.
5. Side Stepping
Stand facing a table or countertop. Place your hands on the countertop for balance. Step to one side. Repeat the movement. Start with 1 set of 10 repetitions on each side.
6. Step Taps Exercise
Stand in front of a step or elevated surface with one hand against the wall or on a railing for balance. Stand with your feet about hip-distance apart and your toes pointing forward. Shift your weight onto your strong leg, step up with your weak foot and tap your toes on the step. Lower your weak foot slowly off the step and onto the floor and repeat the movement. Start with 1 set of 10 repetitions.
Walking exercises are important to relearn this associated movement pattern. Depending on your assessment, walking exercises can start by training in the movement pattern, or simply walking itself. Remember to walk with your back straight. When stepping forward with your weak leg, move the pelvis forward on that side. Try not to let your weak knee snap back. Furthermore, make sure you are supporting as much weight as possible through your weak side.
You may need an assistive device, brace, or helper. If using a cane, hold it in your strong hand. Move the cane, step with your weak leg, and then with your strong leg. Try to make your steps the same length to improve endurance and lessen fatigue.
Additional Management of Post-stroke Rehabilitation
Re-learning patterns of function are achieved by adding treatment strategies such as feedback and practice. Firstly, feedback is done through verbal and tactile cues and guidance. Meanwhile, the practice involves repetitive execution of the movement or task to facilitate neuroplasticity. This practice can be done in a constant repetition of a single task initially, then will distribute the task, then lastly will vary the movement for the challenge.
For strokes affecting sensory function, sensory stimulation is also included in the exercise plan. Examples of sensory stimulation include repetitive sensory activities introducing varying surfaces, mirror therapy, thermal stimulation, compression techniques such as weight-bearing exercises, and intermittent pneumatic compression.
Muscle Tone Management
Changes in muscle tone, such as increased muscle stiffness (spasticity) and decreased muscle tone (flaccidity), can affect the execution of exercises. Thus, additional management for muscle tone is also included in the exercise plan.
Sensory stimulation such as icing, warm compresses, or exercises such as prolonged or quick stretches can help facilitate flaccid muscles or decrease spasticity. Other modalities such as electrical stimulation are used to facilitate muscle contractions or fatigue the muscles to decrease spasticity.
Techniques to Address Visual-Spatial Deficits
Some stroke survivors can demonstrate a lack of awareness of the body on the weak side of the space and environment on the affected side. Some people even develop total unawareness of their disability after a stroke. This can be a challenge to their safety, especially when doing their daily activities. Therefore, these people can benefit from training strategies that encourage awareness and use of the environment on the affected side and the use of the weak extremities.
Cueing in any form (visual, verbal, or movement form) can help direct their attention towards the neglected side. Some examples are a red anchor line that can be taped on the floor so they can visually follow the line from one side to the other, or a red ribbon can be attached to the person’s affected wrist, and they can be directed to keep the red ribbon insight. Another example is a red line drawn in the center of the mirror so stroke survivors can have visual input to realign their body in the midline.
Orthosis and Assistive Devices
An orthosis and assistive devices may be required when problems affect safety. The lack of movement can hinder activities, and on some occasions, increase the risk for falls and incidents. The prescription of orthoses and assistive devices depends on the unique problems each patient presents and how severe their impairments are. The duration of use of orthosis or assistive devices are also considered. Consultation with the doctor, a physical therapist, and a certified orthotist is initiated, especially if a permanent orthosis is needed.
As exercise management is initiated, there are considerations in mind to promote safety. Here are some guidelines to consider:
- Many patients with stroke demonstrate poor hand function, with no effective grasp. Ensure maintained contact with exercise equipment through specialized gloves such as leather mitts with Velcro or wrist cuffs).
- Stroke survivors with impaired sensation are at increased risk for injury and should be monitored closely.
- People with balance and postural deficits should be safely positioned to prevent falls. A stable seat, corner standing while lifting free weights are sample alternatives for ensuring safety.
- Monitoring vital signs (blood pressure, heart rate, breathing rate) is important as there is a high incidence of hypertension and cardiac disease in patients with stroke.
- High-intensity strengthening exercises are generally contraindicated in patients with recent stroke and unstable blood pressure. Isometric exercise that is accompanied by holding breaths, such as the Valsalva maneuver and dangerous elevations in the blood pressure is also contraindicated.
- Dynamic exercises performed in an upright position such as sitting produce fewer elevations in blood pressure than lying down exercises. For patients at risk of intense blood pressure changes, low-intensity exercises are appropriate for initial exercise. Varying the exercises is also an effective strategy to reduce cardiovascular risk.
- Ensure that warm-ups and cooldowns are adequate, and the overall exercise progression is gradual.
Outcomes and Prognosis for Stroke Rehab
After receiving medical treatment for stroke, the golden period for post-stroke rehabilitation is within 3-6 months. This post-stroke rehabilitation period is very crucial because most of the neurological recovery happens during this time. Recovery from stroke is overall fastest in the first weeks and months after its onset. Patients can still make measurable gains for months or years after it occurred, although it is at a reduced rate. Despite the fact that recovery happens early in the time period, late recovery of function is still evident for people with chronic stroke (greater than 1-year post-stroke) who undergo extensive task-specific functional training heavily focused on the affected side.
To explore further the post-stroke rehabilitation, here are the factors considered during recovery from stroke:
- Severity of the stroke: People suffering minor strokes can recover rapidly with few or no residual deficits whereas severely impaired individuals demonstrate more limited and prolonged recovery.
- Initial grade of paralysis: Paralysis is measured upon the initial hospital admission. Complete paralysis upon admission has decreased the chance of complete motor recovery later in rehabilitation.
- Impairments present: Motor and perceptual impairments have the greatest impact on functional performance, but other limiting factors include sensory loss, disorientation, communication disorders, and decreased cardiorespiratory endurance.
- Enablement factors: high motivation, stable supportive family, financial resources, and intensive training with repetitive practice.
- How early the person underwent stroke rehabilitation: Patients who receive inpatient stroke rehabilitation, (skilled occupational, physical, and speech therapy), demonstrate improved motor recovery, functional status, and quality of life at discharge.
- Type of Training: Strong evidence is in support of task-oriented exercise and intensive training as an effective training type for recovery.
Patients who demonstrate less successful rehabilitation outcomes tended to include those with:
- Advanced age
- Severe motor impairments (prolonged paralysis, apraxia)
- Persistent medical problems (incontinence)
- Impaired cognitive function (decreased alertness, poor attention span, judgment, memory, learning difficulty)
- Severe language disturbances
- Severe visuospatial hemineglect
- Other less well-defined social and economic problems.
Stroke recovery requires a steady, repetitive intervention to be successful. Although embarking on the rehabilitation process can be challenging for anyone, making the first step is the hardest part. When you are recovering from a stroke and unable to participate in the activities you enjoyed before, it can be discouraging and difficult to get up and start moving. However, with the right plan, along with coordination of your healthcare provider and adding activities that are meaningful, significant, and fun, continuous recovery can be possible.
