Hemiparesis is a neurological motor impairment where the muscles on one side of the body are weaker than on the other. It is triggered by disruptions in the brain, spinal cord, or nerves connecting the affected muscles. It is a common symptom post-stroke. A 2016 study found that 65% of stroke victims experience hemiparesis.
Experiencing hemiparesis can be scary, but there are many treatments available to address its symptoms and underlying conditions. However, sudden onset of hemiparesis requires urgent medical attention and may be an early sign of stroke. Follow along with our series as we share info and resources all about hemiparesis!

What are the symptoms of hemiparesis?
Hemiparesis, a neurological condition, manifests as weakness or paralysis on one side of the body. It stems from disruptions in the brain, spinal cord, or connecting nerves, often triggered by stroke, brain injury, or other neurological disorders. Symptoms vary but commonly include difficulty walking, maintaining balance, grasping objects, or speaking, as well as muscle fatigue. People with hemiparesis may also experience a tingling or numbed sensation on the affected side of their body.
How is hemiparesis treated?
Recovery from hemiparesis resulting from a stroke is possible. With the right treatment plan, patients can make strides towards their pre-stroke strength and abilities. Here are a few examples of treatments and therapies used to help people with hemiparesis. Electrical stimulation involves placing small electrical pads on the weakened muscles of the affected, hemiparetic side. These pads deliver an electrical charge, prompting muscle contraction. Certain devices are suitable for home use after some practice. Cortical stimulation resembles electrical stimulation, but it targets the brain’s tough membrane (dura mater) with electric currents. During this process, individuals engage in rehabilitation exercises. Modified Constraint-Induced Therapy (mCIT) compels the use of the weakened side, potentially enhancing nerve function with consistent practice. It is an effective option to integrate into a wider treatment plan.
What conditions cause hemiparesis?
Hemiparesis, characterized by weakness or partial paralysis on one side of the body, can stem from various underlying conditions affecting the nervous system. One of the leading causes is stroke. Hemiparesis can be both a side effect of stroke and an early sign of an active stroke. Other triggers include traumatic brain injury, brain tumors, multiple sclerosis, cerebral palsy, and spinal cord injuries. Understanding the diverse range of conditions that can lead to hemiparesis is essential for accurate diagnosis and tailored treatment plans. Each condition presents unique challenges and requires specialized approaches to management. Stay informed about the causes of hemiparesis to advocate for proper care and support.
How does hemiparesis affect gait?
Hemiparesis presents various mobility and strength challenges, including with walking. Hemiparetic gait (walking pattern associated with hemiparesis) typically presents with hip abduction (swinging the leg to the side to compensate for the knee not flexing enough during swing), asymmetric step lengths, decreased speed, stiffness, and an extra-long stance phase on the nonparetic side. Patients with hemiparesis require specific supports to address the affected part of their body to help them get to a similar level of function and control as the other side. This gait is extra tiring and one that is specifically helped by the Agilik boosting the flex and extension of the affected side.
Hemiplegia vs hemiparesis
Understanding these terms is crucial. Both conditions affect only one half of the body, but the degree of impact varies. Hemiparesis involves partial weakness or paralysis on one side, while hemiplegia is complete paralysis. Both stem from disruptions in the nervous system but present differently. Hemiparesis commonly occurs post-stroke, affecting muscle strength but not fully paralyzing. Recognizing these nuances aids in accurate diagnosis and tailored treatment. The Agilik, for example, can help with hemiparetic gait but not with hemiplegia.
