G83.21

Clinical Causes: Stroke or cerebrovascular accident (most common cause): blocks blood flow to brain areas controlling movement Brain tumors or lesions: affecting motor regions of the cerebral cortex Traumatic brain injury: resulting from accidents or blows to the head Multiple sclerosis: demyelination disrupting nerve signals Infections affecting the nervous system: such as encephalitis or meningitis Congenital neurological conditions: present from birth Neurodegenerative diseases: like amyotrophic lateral sclerosis (ALS)

Key Symptoms: Weakness or paralysis in the right arm, affecting movement and strength Difficulty with tasks requiring fine motor skills, such as writing or buttoning clothes Potential muscle wasting or atrophy over time Decreased coordination and dexterity Possible numbness or sensory deficits in the affected limb Altered reflexes or muscle tone In rare cases, associated weakness in neighboring muscles or limbs

Diagnosis Path: physical examination to assess muscle strength, tone, and reflexes; neurological assessments; and imaging tests such as MRI or CT scans to identify brain or spinal cord abnormalities. Additional tests may include blood work to detect underlying infections or metabolic causes, and neurophysiological studies like electromyography (EMG) placed to evaluate nerve and muscle function.

Treatment Protocols: Physical therapy: designed to improve strength, flexibility, and mobility of the affected limb Occupational therapy: aimed at helping individuals adapt to functional limitations and regain independence in daily activities Medications: such as antispasticity drugs, pain relievers, or medications targeting underlying conditions like infections or autoimmune disorders Assistive devices: including braces, splints, or mobility aids to support movement Surgical interventions: in certain cases, to relieve pressure or repair damaged structures Alternative therapies: like acupuncture or neuromuscular electrical stimulation, as adjuncts to standard treatment
