The timeline for recovering from post-stroke numbness can vary widely. While some patients start to experience recovery within the first few months, others may need consistent rehabilitation to regain sensation. By leveraging targeted treatment options like sensory retraining, mirror therapy, and advanced therapies such as Hyperbaric Oxygen Therapy (HBOT), some patients may see improvements in sensation within months, though recovery timelines vary widely and can extend over several years. Here, we explore the causes of post-stroke numbness and highlight strategies that can support and potentially accelerate sensation recovery.
Why do I feel numb?
A stroke occurs when blood flow in the brain is interrupted, either through a clot blocking an artery (ischemic) or by a rupture in blood vessels (hemorrhagic). Areas deprived of blood may sustain damage due to cell death, leading to tissue damage and loss of function. The thalamus, parietal lobe, and occipital lobe are key brain regions for sensory function, and numbness is common when these areas are affected. If you experience new or sudden numbness or tingling, this could be a medical emergency. Knowing stroke warning signs and seeking immediate medical attention is essential.
What factors affect numbness recovery after stroke?
The time to regain sensation depends on factors such as stroke type, location, and rehabilitation intensity. Hemorrhagic stroke patients typically experience greater initial impairment but may recover faster than those with ischemic strokes of comparable severity. Stroke type and location do not determine progress alone. Rehabilitation efforts have a major impact on recovery. Many patients experience the most significant progress within the first few months, though improvements may continue over years with consistent rehabilitation, albeit at a slower pace. Patients who take control of their care, in partnership with providers, often see the best outcomes.
What can I do to treat numbness?
Sensory Retraining: Sensory retraining can be a valuable treatment for post-stroke numbness, using repetitive exercises to stimulate sensory pathways and support brain retraining. This approach often includes activities with items of various textures, such as sandpaper, silk, or sponges, which are used to help with sensory differentiation. Exercises might involve identifying objects by touch alone or performing body-location identification exercises with different textures, which can be accessible with everyday items.
Mirror Therapy: Mirror therapy uses a mirror to create the illusion of moving the affected limb, helping activate mirror neurons in the brain and supporting sensory recovery. Typically, this involves placing the mirror beside the unaffected limb so its reflection creates an illusion of movement in the affected limb, potentially stimulating neural pathways associated with sensory recovery.
Electrical Stimulation: Functional electrical stimulation (FES) or TENS machines may stimulate sensation in the affected limb. Electroacupuncture has also shown promise in promoting neuroplasticity for patients with sensory deficits. FES devices allow for low-intensity settings that can gradually be increased to activate sensory nerves in the targeted area.
Proper Positioning and Support: Positioning and supporting the affected limb with slings, harnesses, or pillows helps prevent further damage and supports recovery. Proper positioning can involve using pillows to support the affected limb while resting and avoiding prolonged unsupported positions. Slings, harnesses, or cushions can reduce strain on the limb during daily activities, helping prevent additional injury and supporting gradual recovery.
Physical and Occupational Therapy: Working with therapists to perform exercises that improve strength, flexibility, and range of motion addresses both numbness and other post-stroke issues. Therapies often involve range-of-motion exercises, such as gently extending and flexing joints, and may use tools to build grip strength. Occupational therapists frequently introduce tasks like dressing or grooming, targeting both functional recovery and improved mobility in the affected limb.
Constraint-Induced Movement Therapy (CIMT): CIMT involves extensive use of the affected arm while restricting the unaffected arm, increasing brain activity in the affected area. CIMT often includes focused tasks with the affected arm, such as picking up objects or stacking small items, while the unaffected arm is restricted. Practicing these tasks for short periods daily can help boost neuroplasticity and recovery in the affected limb over time.
Hyperbaric Oxygen Therapy (HBOT): HBOT involves breathing oxygen-rich air in a pressurized chamber, which may aid neuroplasticity, cell repair, and reduce inflammation, supporting sensation recovery. HBOT sessions typically last around 60–90 minutes at a pressure of 2.0 ATA, allowing oxygen to dissolve into blood plasma and other fluids.
Can hyperbaric oxygen therapy (HBOT) help with numbness?
HBOT enhances oxygen delivery by increasing atmospheric pressure, which allows oxygen to dissolve into blood plasma, cerebrospinal fluid, and lymphatic fluid. This oxygen can penetrate deeper into tissues, reaching areas that need it most. Research suggests HBOT may support angiogenesis and neuron repair, mechanisms that are still being studied for their role in sensation recovery after stroke.
Early research has explored HBOT's potential role in chronic post-stroke recovery. These are small, limited studies, and individual results vary widely:
Hadanny et al. (2020) : In a study of 162 chronic stroke patients, participants who received HBOT reported cognitive, motor, and sensory improvements. As a single observational study, these findings are preliminary and are not a prediction of individual outcomes.
Efrati et al. (2013) : A randomized trial with 74 chronic stroke patients reported increased neuronal activity and improvements in sensation, motor function, and language in the HBOT group. Larger studies are needed to confirm these early findings.
HBOT is an area of ongoing research that some patients in the chronic post-stroke stage explore as an adjunct to traditional therapy. By increasing oxygenation and blood flow in the brain, HBOT may support neuroplasticity and cell repair, though its role in sensory and functional recovery is still being studied.
Is HBOT right for you?
HBOT can be a valuable addition to post-stroke recovery plans for patients seeking to improve sensation. Discuss HBOT with your healthcare provider to see if it aligns with your recovery goals and needs.
At OxyRenew in Los Angeles, we offer a private, comfortable 2.0 ATA seated hyperbaric chamber experience for optimal recovery. We focus on evidence-based therapies, supporting patients with post-stroke numbness through scientifically supported care and guidance.
Conclusion
The journey to regain sensation post-stroke can be challenging, but with dedication and the right care plan, improvements are possible. HBOT is one adjunct some patients explore to support recovery alongside established rehabilitation.
