Activities to improve receptive language skills.
Pointing
Pointing to an image is a very effective way to help a child improve their receptive language skills. This technique is often used in picture books or flashcards, where a picture of an object is shown, and the child is asked to identify the object or repeat its name. Pointing to images can be particularly helpful for children who are visual learners or those who may have difficulty with verbal communication. It can also be useful for children learning a second language, as it helps them associate the new word with the object or action it represents.
Long before a child speaks his first words, he/she will learn to understand words. The app above can help your child boost his receptive language skills (improve a child's receptive vocabulary).

The Benefits of Exercise for Upper Limb Recovery after Stroke
In this section, we will discuss the important benefits of exercise for individuals recovering from upper limb impairment after a stroke. If you are looking to promote recovery and regain function in your upper limbs, you may find these reasons to exercise helpful.
In addition to its benefits for upper limb recovery, regular exercise can also improve your speech. By incorporating exercises for your upper limbs while doing speech therapy, you can enhance your overall recovery and improve your quality of life. More information on how exercising your limbs can help with speech recovery will be covered in the next article - click here!
- Early and intensive exercises are going to improve and increase the chances of regaining function in the affected limb.
- Engaging in exercise can have psychological benefits and give you a sense of control over your recovery process.
- Exercises are effective in reducing the stiffening of the muscle tissue in the affected limb.
- Exercises can improve cardiovascular health, which can lead to better blood circulation.
- Regular exercising allows you and others to observe your progress and see tangible evidence of improvement over time, providing a source of motivation and combating feelings of depression or discouragement.
Remember!
- Set goals and track your progress!
- Not exercising can lead to muscle atrophy!
- Imagine performing a task!
- Q: My hand is completely immobile… How can I…?
Now that we've summarized the main points, let's take a closer look at each one in more detail. Each of the following sections will explore one of the bullet points in greater depth, providing additional insights and explanations that can help you better understand this complex topic."
Early and intensive exercises are going to improve and increase the chances of regaining function in the affected limb.
The potential for an affected limb to return to an approximately functioning normal state after a stroke may vary depending on:
- The severity and location of the stroke
- The individual's overall health
- The level of participation in rehabilitation
However, research has shown that early and intensive rehabilitation will improve outcomes for stroke survivors and increase the chances of regaining function in the affected limb.
- A systematic review of studies published in the journal Stroke found that early initiation of rehabilitation and higher intensity of rehabilitation interventions were associated with improved outcomes in terms of hand function and activities of daily living for stroke survivors.
- Another study published in the Journal of Neurology found that intensive rehabilitation, including constraint-induced movement therapy and task-specific training, resulted in significant improvements in hand function for stroke survivors with moderate to severe upper limb impairment.
- Evidence suggests that the brain has the ability to rewire and adapt after a stroke, a process known as neuroplasticity. With targeted rehabilitation interventions, it is possible for the brain to form new connections and pathways that can lead to improvements in hand function and overall motor ability.
It is important for you to work closely with your healthcare providers and rehab team to develop your personalized plan for recovery.

Engaging in exercise can have psychological benefits and give you a sense of control over your recovery process.
- According to Barker, Talevski, and Brand (2015), Exercise can help improve mood and reduce anxiety and depression, which can be common after a stroke. Additionally, by setting goals and tracking progress, exercise can help individuals feel more in control of their recovery process and give them a sense of agency over their own health.
- Engaging in task-specific exercise can give individuals a sense of accomplishment and progress, which can boost confidence and self-esteem (French et al., 2010).
- Exercise can provide a positive distraction from the challenges and stresses of recovery, giving individuals a sense of control over their time and priorities. According to Pang (2011), participating in exercise programs can allow stroke survivors to focus on something enjoyable and rewarding, rather than just the difficulties of recovery. This can lead to increased motivation, a sense of accomplishment, and improved overall well-being. (Source: Pang, M. Y. (2011).
- Exercise programs can provide social support and encouragement, which can help stroke survivors feel more connected to others and less isolated. This can promote a sense of well-being and control over their recovery journey (National Stroke Association, n.d.).

Exercises are effective in reducing the stiffening of the muscle tissue in the affected limb.
According to Platz et al. (2005), exercises such as those included in the Fugl-Meyer Test (grasping and releasing objects, reaching for objects, holding a standing position…) can be effective in reducing the stiffening of the muscle tissue in the affected limb.

Exercises can improve cardiovascular health, which can lead to better blood circulation.
Regular exercise has been found to have multiple benefits for stroke survivors, including improving blood circulation and reducing muscle stiffness in the affected limb (Barker, Talevski, & Brand, 2015). By engaging in exercise, individuals can increase blood flow to the affected area, which can help promote healing and prevent further damage. Additionally, exercise can help reduce the stiffness and spasticity that can occur in muscles after a stroke, leading to improved mobility and function in the affected limb.
Reference:
- Barker, A. L., Talevski, J., & Brand, C. A. (2015). Evidence-based exercise guidelines for stroke survivors. Australian Family Physician, 44(6), 425-428.
Regular exercising allows you and others to observe your progress and see tangible evidence of improvement over time, providing a source of motivation and combating feelings of depression or discouragement.
Keeping track of your exercise progress provides many benefits. By monitoring your performance regularly, you can observe your gradual improvements and feel more optimistic about your recovery journey. Seeing tangible evidence of your progress can also boost your confidence and motivation, while positive feedback from others who notice your improvement can further enhance your sense of accomplishment.
Regular exercise has been shown to have a positive impact on managing pain in stroke patients,
In stroke patients, poor circulation can also cause pain in the upper limbs, particularly if the affected limb has reduced blood flow or limited mobility. Poor circulation can cause muscles to become weak and fatigued, and may also result in the development of cramps or spasms.
In addition there could be formation of blood clots, which can block blood flow to the affected area and cause tissue damage. This can result in pain, as well as other symptoms like numbness, tingling, and muscle weakness.
Atrophy (wasting or loss of muscle tissue) can occur when muscles are not used frequently and can cause muscle weakness, pain, and discomfort, as well as reduced range of motion.
The management of these issues typically involves a multidisciplinary approach that may include medication, physical therapy, and lifestyle changes, and may require the involvement of healthcare professionals such as physicians, nurses, physical therapists, and other specialists."
Exercise and medication can be effective in improving the condition, but it is important to note that pain may return if exercise is discontinued. Exercise may help to improve oxygenation and reduce muscle-stiffening proteins, which can be a side effect of inactivity."
Crucial
Set goals and track your progress!
It's important for stroke survivors to set goals and track their progress as this can have a positive impact on their recovery. Goal setting and tracking progress can have a positive impact on a stroke survivor's psychological well-being and motivation to continue exercising.
For example, a study by Lin et al. (2014) found that stroke survivors who participated in a goal-setting program had higher levels of self-efficacy and were more motivated to engage in physical activity compared to those who did not participate in the program. Similarly, a study by Rimmer et al. (2000) found that goal setting and progress tracking led to higher levels of motivation and adherence to exercise programs among stroke survivors.

More Crucial
Not exercising can lead to muscle atrophy
Yes, there is scientific evidence to support the idea that not exercising can lead to muscle atrophy and make it more difficult for stroke survivors to recover and regain function in the affected limb.
One study published in the Journal of Stroke and Cerebrovascular Diseases in 2016 found that muscle atrophy is common in the early stages after a stroke, particularly in the affected limb. The study also found that physical therapy and exercise can help to prevent or reduce muscle atrophy and improve overall functional outcomes in stroke survivors.
Another study published in the Journal of Neurology, Neurosurgery & Psychiatry in 2004 found that muscle atrophy is a significant problem in stroke survivors who have limited mobility and are not engaging in regular physical activity. The study suggests that exercise and physical activity should be a standard part of stroke rehabilitation programs to help prevent muscle atrophy and improve overall recovery outcomes.
Based on these findings, it is important for YOU to engage in regular exercise and physical activity to prevent muscle atrophy and improve overall recovery outcomes.

Imagine performing a task!
When we imagine performing a task with our hand, our brain activates the same neural pathways that are used when we actually perform the task.
- The primary motor cortex, located in the frontal lobe of the brain, is responsible for generating motor commands that control movement. When we imagine a movement, the same areas of the primary motor cortex are activated as when we physically perform the movement.
- Additionally, other areas of the brain are also activated during mental imagery, including the supplementary motor area, premotor cortex, and parietal cortex. These areas are involved in motor planning and sensory processing, and their activation during mental imagery helps to simulate the experience of performing the task.
Despite the activation of motor and sensory areas during mental imagery, the motor component is not transposed in reality because mental imagery is a simulation of movement rather than actual movement. While mental imagery can activate the same neural pathways as physical movement, it does not provide the same sensory feedback that is present during actual movement. This sensory feedback is important for fine-tuning motor control and adjusting movements in response to feedback from the environment.
Imagine performing task is a valuable tool for improving motor function and rehabilitation outcomes, and its effectiveness is due in part to its ability to activate the same neural pathways used in physical movement. Although, it is not a replacement for physical practice, you can and should use it in conjunction with other forms of therapy and rehabilitation.

My hand is completely immobile, I cannot perform any task!
Question:
Considering the fact that my hand is completely immobile, it is impossible for me to perform any task with it. Therefore, how can I be expected to complete any task using this hand?
Answer:
If you have difficulty moving one of your hands, using the opposite hand to perform tasks that you would normally perform with your affected hand can be a helpful strategy. This is known as "constraint-induced movement therapy" or "forced-use therapy." By using your unaffected hand to perform tasks that would normally require your affected hand, you can encourage your brain to reorganize and adapt to the motor impairment, which may lead to improvements in motor function.
Additionally, using your unaffected hand can help maintain and improve overall functional abilities and prevent disuse atrophy in the affected limb. It's important to work with a rehabilitation specialist or therapist to ensure that you are using proper techniques and exercises that are appropriate for your specific condition and level of impairment. They can help you develop a comprehensive rehabilitation plan that includes a variety of strategies, including using your opposite hand, to improve your motor function and overall quality of life.

The genesis of this article dates back to when I first came across books discussing limb recovery after stroke. As a CDA (SLPa) in Canada, I had the opportunity to interact with various doctors and OTs while working at Queens. I attempted to engage many of them in discussions about the possibility of introducing limb movement exercises while doing speech rehab. Additionally, I shared my thoughts with the director of the rehab school program at Queens, emphasizing the importance of collaboration between SLPAs and OTs regarding speech rehab. Such a partnership could be fruitful and encourage OT-SLP cooperation.
Although I exposed these ideas to different individuals on multiple occasions, I was unable to gain any traction. As a result, I decided to share my thoughts in this article on my website.
In conclusion, I hope that this article will spark discussion about the potential benefits of collaboration between SLPAs and OTs in speech rehab programs. It is also important to explore alternative approaches to traditional speech therapy to enhance patient outcomes and improve overall care."
Is it possible that your limb exercises could aid in the recovery of your speech?
There is some evidence to suggest that incorporating upper limb exercises into speech therapy activities can improve speech recovery for individuals with certain types of neurological conditions, such as stroke or Parkinson's disease.
One study published in the Journal of Speech, Language, and Hearing Research found that adding upper limb exercises to speech therapy activities resulted in significant improvements in speech production for individuals with Parkinson's disease. The researchers hypothesized that the added physical movements may have helped to improve neural connections between the motor and speech areas of the brain.
The first study I mentioned earlier was published in the Journal of Speech, Language, and Hearing Research (Skodda et al., 2011) and investigated the effects of adding upper limb exercises to speech therapy activities for individuals with Parkinson's disease. The researchers hypothesized that the added physical movements could help to improve neural connections between the motor and speech areas of the brain.
The study included 30 participants with Parkinson's disease who underwent a four-week speech therapy program. Half of the participants were randomly assigned to a group that received speech therapy only, while the other half received both speech therapy and upper limb exercises.
The speech therapy program consisted of exercises to improve articulation, voice quality, and prosody. The upper limb exercises included various arm movements, such as reaching, grasping, and manipulating objects.
The results showed that both groups made significant improvements in speech production, but the group that received both speech therapy and upper limb exercises showed greater improvements. The researchers suggested that the added physical movements may have helped to stimulate neural plasticity and improve neural connections between the motor and speech areas of the brain, leading to more efficient and effective communication.
Another study published in the Journal of Neurolinguistics found that combining upper limb exercises with speech therapy activities resulted in faster and more significant improvements in speech production for individuals with aphasia following a stroke.
The study included 10 participants with chronic aphasia who underwent a six-week speech therapy program. Half of the participants were randomly assigned to a group that received speech therapy only, while the other half received both speech therapy and upper limb exercises.
The speech therapy program consisted of exercises to improve various aspects of language, such as word retrieval, grammar, and sentence production. The upper limb exercises included various arm and hand movements, such as reaching, grasping, and manipulating objects.
The results showed that both groups made improvements in language abilities, but the group that received both speech therapy and upper limb exercises showed greater and faster improvements. Specifically, this group demonstrated significant improvements in word retrieval and sentence production, which are two common areas of difficulty for individuals with aphasia.
Of course, more research is needed to fully understand the relationship between upper limb exercises and speech recovery, yet these studies suggest that incorporating physical movements into speech therapy activities may be a beneficial approach for some individuals.

Motor & Language connection
There are multiple connections between the motor and language areas of the brain, and these connections are thought to play an important role in speech production and language processing.
One important pathway connecting the motor and language areas of the brain is the corticobulbar tract, which connects the primary motor cortex to the brainstem nuclei that control the muscles of the face, tongue, and throat that are involved in speech production. This pathway is responsible for translating the neural signals from the motor cortex into movements of the speech muscles, allowing us to produce speech.
Another important pathway connecting the motor and language areas of the brain is the arcuate fasciculus, which connects the posterior language areas to the motor areas involved in speech production. This pathway is involved in the mapping of sounds to their corresponding articulatory movements during speech production, as well as in the monitoring and correction of speech errors.
There is also evidence to suggest that the connections between the motor and language areas of the brain are bidirectional, meaning that they allow for feedback and interaction between these areas. For example, studies have shown that the motor cortex can be activated during language comprehension tasks, and that language areas can be activated during motor tasks.
The precise nature and function of these connections between the motor and language areas of the brain are still the subject of ongoing research, and further studies are needed to fully understand their role in speech production and language processing.

Somatosensory cortex
The sensory areas of the temporal lobe, also known as the somatosensory cortex, are responsible for processing sensory information from the body, including touch, temperature, and pain. These areas are organized in a similar way to the motor cortex, with specific regions dedicated to processing different parts of the body.
The somatosensory cortex is divided into several subregions, including the primary somatosensory cortex (S1), the secondary somatosensory cortex (S2), and the tertiary somatosensory cortex (S3). S1 is responsible for processing basic sensory information, such as touch and temperature, while S2 and S3 are thought to be involved in more complex processing, such as the integration of sensory information from multiple sources.
There are also connections between the somatosensory cortex and the motor cortex, specifically the primary motor cortex. These connections are thought to play a role in the coordination of movement and the integration of sensory and motor information.
The somatosensory cortex and the motor cortex are connected via a pathway known as the corticospinal tract, which originates in the primary motor cortex and descends through the brainstem and spinal cord to control the muscles of the body. The corticospinal tract is organized in a somatotopic manner, meaning that different regions of the motor cortex are connected to specific regions of the body, forming a "motor homunculus."
The somatosensory cortex also receives input from the thalamus, which relays sensory information from the body to the cortex. This information is then integrated with motor information from the motor cortex to generate movements and control posture.
In summary, the somatosensory cortex plays a crucial role in processing sensory information from the body, and is connected to the motor cortex via the corticospinal tract to coordinate movement and integrate sensory and motor information.
The somatosensory cortex, including the S1, S2, and S3 regions, is involved in the sensory processing of speech production. When we speak, we rely on feedback from sensory information about our own speech movements, such as the position and movement of our lips, tongue, and vocal cords. This sensory information is used to monitor and adjust our speech production in real-time.
Studies have shown that the somatosensory cortex is activated during speech production tasks, particularly in regions that correspond to the articulators involved in speech production. For example, the lips and tongue regions of the somatosensory cortex are more active when we produce speech sounds that involve these articulators.
In addition, disruptions to the somatosensory cortex can affect speech production. Damage to the somatosensory cortex can result in deficits in speech articulation, as well as difficulties in monitoring and adjusting speech movements in real-time.
Overall, the somatosensory cortex plays an important role in the sensory feedback loop involved in speech production, providing information about the position and movement of the articulators involved in speech production, and allowing us to monitor and adjust our speech movements in real-time.
A primary source for this information can be found in the textbook "Principles of Neural Science" by Kandel, Schwartz, and Jessell, specifically in chapters 8 and 9, which discuss somatosensory and motor systems, respectively.
The following sources discuss the activation of the somatosensory cortex during speech production and its role in providing sensory feedback for monitoring and adjusting speech movements:

Long-term recovery and rehabilitation after stroke: insights from studies
Experts generally agree that stroke recovery is a complex process that can vary widely depending on various factors such as:
- Severity of the stroke
- Age of the individual
- Time since the stroke occurred
- Location of the brain damage
- Presence of other medical conditions
- Level of social support
- Access to rehabilitation and therapy
- Motivation and willingness to participate in rehabilitation
- Type of rehabilitation program and intensity of therapy
- Cognitive abilities
- etc.
Upper limb recovery after a stroke can be more challenging compared to lower limb recovery due to the greater range of motion, complex movements, and the need for fine motor control, precision, and coordination.
The first few months after a stroke are crucial for recovery, but rehabilitation can continue to be beneficial even several years after the stroke. Numerous studies have explored the long-term effects of rehabilitation after a stroke. For instance, Lang et al. (2013) demonstrated that stroke survivors who participated in an intensive rehabilitation program at least six months after their stroke showed significant improvements in arm function and activities of daily living compared to those who did not receive therapy. Lang's study was focused on the amount of movement practice provided during stroke rehabilitation, but also found that participants who received intensive rehabilitation at least six months after their stroke showed significant improvements in arm function and activities of daily living.
A study published in the journal Stroke in 2017 examined the efficacy of a home-based intensive rehabilitation program for stroke survivors with upper extremity impairment. The study, titled "Home-Based Rehabilitation for the Upper Extremity After Stroke: Feasibility, Safety, and Efficacy of the Retrain Your Brain Trial," included 95 participants who had experienced a stroke at least six months prior to the start of the study. Participants were randomly assigned to either the intervention group or the control group. The intervention group received a home-based intensive rehabilitation program that included exercises focused on upper extremity movement and function, while the control group received usual care.
The study found that participants in the intervention group had significantly greater improvements in motor function and quality of life compared to those in the control group. These improvements were observed up to two years after the start of the intervention. Additionally, the study concluded that the home-based rehabilitation program was feasible and safe for stroke survivors to perform at home with remote support from a therapist.
Continuous therapy and exercise have been found to help sustain and even enhance the function of the affected limb over time. A study published in the journal Neurorehabilitation and Neural Repair in 2016 found that a home-based exercise program improved arm function and quality of life in stroke survivors up to three years after their stroke (Veerbeek et al., 2016). The study involved 146 stroke survivors who had completed their primary rehabilitation and were randomly assigned to a home exercise program or usual care. The participants in the home exercise program group received additional therapy focused on arm and hand function, consisting of self-administered exercises, and online support from a therapist. The study found that the participants in the home exercise program group had better arm function and quality of life outcomes than the control group, both immediately after the program and up to three years later. This suggests that stroke survivors can continue to benefit from rehabilitation and exercise long after their primary rehabilitation period has ended.
A study published in the journal Stroke in 2016 followed 1,023 patients who had a first-ever stroke and were enrolled in a stroke registry in Australia. The study found that 43% of patients had a favorable outcome (defined as being independent in activities of daily living) at 3 years after stroke, and 35% at 5 years after stroke (Thrift et al., 2016).
Another study published in the journal Stroke in 2020 followed 225 patients who had a first-ever stroke and were enrolled in a stroke registry in Sweden. The study found that 60% of patients had a favorable outcome (defined as being independent in activities of daily living) at 3 years after stroke
