Summary
Motor recovery after intracerebral hemorrhage (ICH) can continue for years. About 10% of patients achieve delayed motor recovery, highlighting the importance of long-term monitoring for stroke survivors.
Area of Science:
- Neurology
- Neurosurgery
- Rehabilitation Medicine
Background:
- Spontaneous intracerebral hemorrhage (ICH) recovery data beyond one year is limited.
- Understanding long-term motor recovery profiles is crucial for patient management and rehabilitation strategies.
Purpose of the Study:
- To describe the temporal profile of long-term motor recovery up to one year after spontaneous intracerebral hemorrhage (ICH).
- To identify factors associated with motor recovery and analyze recovery rates in a large cohort.
Main Methods:
- A multicenter cohort study included non-herniated supratentorial ICH patients.
- Follow-ups were conducted at 3 months, 6 months, 1 year, and annually thereafter.
- Motor recovery was assessed by independent standing ability.
Main Results:
- 6.5% of patients regained motor recovery beyond one year, with recovery continuing up to 44 months.
- One-year and long-term cumulative recovery rates were 71.3% and 80.2%, respectively.
- Age, ICH location, hematoma volume, intraventricular extension, GCS score, and hospital tier independently influenced motor outcomes. Older age was a hazard factor for delayed recovery.
Conclusions:
- Motor recovery after ICH can extend beyond one year, continuing for approximately three years.
- Delayed motor recovery constitutes about 10% of all achieved recoveries, emphasizing the need for extended rehabilitation observation.

01:24Muscle Recovery and Fatigue
4.5K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:17Exercise and Cardiac Output
4.0K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

01:15Ischemic Stroke ll: Pathophysiology
68
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

01:29Hemorrhagic Stroke ll: Pathophysiology
52
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

01:25Secondary Spinal Cord Injury llI: Pathophysiology
68
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
