Arginase deficiency — hyperargininemia (OMIM #207800), caused by biallelic pathogenic variants in ARG1 (encoding arginase 1, the cytosolic enzyme catalyzing the final step of the urea cycle — the hydrolysis of arginine to ornithine and urea in periportal hepatocytes, also expressed in erythrocytes), the rarest of the proximal urea cycle disorders with an estimated incidence of 1 in 300,000 to 1 in 1,000,000 live births — with enzymatic deficiency resulting in the failure to cleave arginine, producing progressive hyperargininemia as the primary biochemical hallmark rather than the severe neonatal hyperammonemia that characterizes the other urea cycle disorders, and presenting with a strikingly different and predominantly neurological natural history — manifests with a clinical course that is almost exclusively neurological and progressive rather than episodic and hepatic: the characteristic presentation begins in the first 2–5 years of life with progressive spastic diplegia (the most distinctive and debilitating feature — a lower extremity spasticity that progresses to a scissors gait, toe-walking, and eventually loss of independent ambulation, attributable to arginine accumulation in the CNS producing neuronal toxicity via impaired guanidinium compound metabolism and excitatory amino acid receptor activation), accompanied by progressive intellectual disability (ranging from mild to severe), seizures (particularly generalized tonic-clonic and absence seizures), microcephaly from progressive cerebral atrophy, and growth retardation, with the metabolic crises of severe acute hyperammonemia seen in other urea cycle disorders being unusual in arginase deficiency — acute crises occurring primarily during severe catabolic stress or with high-protein dietary loading — and the predominant clinical burden being the slowly progressive neurodegeneration from chronic arginine accumulation rather than episodic ammonia-driven encephalopathy. Arginase deficiency is biochemically characterized by markedly elevated plasma arginine (typically 200–1500 µmol/L, reference range 20–120 µmol/L — often 10–20 times normal), moderately elevated plasma ammonia (milder than other UCDs; typically 80–200 µmol/L rather than the severe acute elevations seen in OTC deficiency or citrullinemia), elevated cerebrospinal fluid arginine (reflecting CNS arginine accumulation that correlates with spasticity severity), elevated plasma guanidino compounds (guanidinoacetate, homoarginine, N-alpha-acetylarginine — byproducts of arginine overflow metabolism), and elevated urinary orotic acid and arginine — representing a disease where monitoring platform reliability is directly linked to the arginine accumulation neurotoxicity trajectory, the progressive spasticity and intellectual disability management obligations, the seizure monitoring demands, and the dietary and pharmacological management optimization that determine whether the progressive neurological decline can be slowed or partially reversed.
Arginase deficiency technology platforms — encompassing the plasma amino acid monitoring platforms measuring arginine (the primary therapeutic target, with plasma arginine reduction the goal of dietary protein restriction and nitrogen scavenger therapy), ornithine, glutamine, and the guanidino compound profile, the molecular genetics platforms performing ARG1 sequencing and deletion/duplication analysis (over 60 ARG1 pathogenic variants described), the arginase 1 enzyme activity assay platforms measuring enzyme activity in erythrocytes (the most accessible tissue with high arginase 1 expression — facilitating biochemical diagnosis without liver biopsy), the neurological examination and spasticity assessment platforms tracking progressive lower extremity spasticity, gait analysis, ambulation status, and the Ashworth scale for spasticity severity, the neuroimaging platforms performing brain MRI and MR spectroscopy (brain MRI typically showing cerebral atrophy, white matter signal abnormalities, and cortical thinning reflecting chronic arginine neurotoxicity), the EEG monitoring platforms for seizure surveillance and antiepileptic management, the neurodevelopmental and neuropsychological assessment platforms tracking IQ, adaptive behavior, and educational trajectory longitudinally, the dietary management platforms supporting protein restriction with essential amino acid supplementation and arginine-free amino acid formula, the nitrogen scavenger therapy monitoring platforms overseeing sodium phenylbutyrate or glycerol phenylbutyrate and sodium benzoate therapy with plasma arginine monitoring, the spasticity management platforms coordinating baclofen, tizanidine, botulinum toxin injection, and intrathecal baclofen therapy records, and the physical and occupational therapy platforms tracking motor development and adaptive function — must maintain the availability and performance standards required by the progressive neurological monitoring complexity, the arginine accumulation burden tracking demands, the multi-specialty spasticity management coordination obligations, and the neurodevelopmental surveillance that determines educational and therapeutic intervention intensity. This guide explains why arginase deficiency tech platforms need dedicated monitoring, what components to monitor, and how to build a monitoring strategy matched to the progressive neurological disease trajectory, arginine accumulation monitoring complexity, spasticity management demands, and lifelong neurodevelopmental surveillance obligations of arginase deficiency.
Why Arginase Deficiency Tech Platforms Require Specialized Monitoring Attention
Arginase deficiency management presents monitoring challenges shaped by the progressive neurological disease trajectory, the arginine accumulation neurotoxicity burden, the multi-specialty spasticity management complexity, and the seizure monitoring obligations: the progressive neurological disease trajectory — unlike the other urea cycle disorders characterized by episodic hyperammonemic crises, arginase deficiency produces a slowly progressive spastic paraplegia and intellectual disability from chronic arginine neurotoxicity; the neurological monitoring platforms tracking gait, spasticity severity, ambulation status, and cognitive trajectory provide the longitudinal data that determines whether dietary arginine restriction is achieving sufficient metabolic control to slow neurological progression; platform failures disrupting serial neurological assessment records prevent the early detection of progression that justifies escalation of arginine-lowering therapy; the arginine accumulation neurotoxicity burden — plasma arginine above 300–400 µmol/L is generally considered the threshold for neurological toxicity; the tighter the plasma arginine control (targeting below 200 µmol/L on treatment), the better the neurological outcomes; platform failures disrupting plasma amino acid monitoring allow plasma arginine to rise undetected into the neurotoxic range during dietary non-compliance or intercurrent illness; the multi-specialty spasticity management complexity — progressive lower extremity spasticity in arginase deficiency requires coordinated management across neurology (antispastic pharmacotherapy), orthopedics (hip subluxation, scoliosis monitoring), rehabilitation medicine (physical and occupational therapy, orthoses, adaptive equipment), and in severe cases neurosurgery (intrathecal baclofen pump implantation, selective dorsal rhizotomy); and the seizure monitoring obligation — approximately 40% of arginase deficiency patients develop seizures requiring antiepileptic management with regular EEG surveillance.
Plasma arginine platforms are the primary metabolic monitoring tool in arginase deficiency — the degree of plasma arginine reduction on dietary protein restriction and nitrogen scavenger therapy is the most important modifiable determinant of neurological trajectory. Plasma arginine above 300–400 µmol/L in a child with arginase deficiency represents inadequate metabolic control with ongoing neurological toxicity risk; plasma arginine reduction to below 200 µmol/L on treatment correlates with stabilization of spasticity progression and improved neurodevelopmental outcomes; a platform failure disrupting plasma amino acid monitoring for a 7-year-old with arginase deficiency on sodium phenylbutyrate and protein-restricted diet delays the detection of plasma arginine elevation from dietary non-compliance during the school year, allowing undetected metabolite accumulation that will translate into additional spasticity progression before the next clinic visit. Monitor at 1-minute intervals during laboratory hours. Alert immediately.
Neurological examination and gait analysis platforms are essential for tracking the progressive spasticity trajectory in arginase deficiency, the clinical endpoint most directly attributable to arginine neurotoxicity and most responsive to arginine-lowering therapy. The Modified Ashworth Scale for lower extremity spasticity, gait analysis (temporal-spatial parameters, step length, cadence, velocity), ambulation status (community ambulation, household ambulation, non-ambulatory), and lower extremity motor function provide the longitudinal clinical data that correlate with plasma arginine control and determine whether therapy is protecting the motor function that defines independence and quality of life in arginase deficiency; platform failures disrupting serial neurological examination records prevent the detection of spasticity progression that justifies escalation of arginine-lowering therapy or advancement of spasticity management interventions.
EEG platforms are critical for seizure monitoring in arginase deficiency, where seizures are common and antiepileptic management is guided by serial EEG surveillance. Approximately 40% of arginase deficiency patients develop seizures; EEG demonstrates interictal epileptiform discharges and ictal patterns requiring antiepileptic drug initiation and dose adjustment; poorly controlled seizures contribute to the cognitive decline trajectory and impair rehabilitation participation; platform failures disrupting EEG records delay the seizure diagnosis and antiepileptic management that prevents seizure-related cognitive injury on top of the background arginine neurotoxicity.
What to Monitor on an Arginase Deficiency Care Tech Platform
Plasma Arginine and Biochemical Monitoring
Monitor plasma amino acid profile records (plasma arginine — primary monitoring target; markedly elevated at diagnosis typically 200–1500 µmol/L; therapeutic target below 200 µmol/L on treatment; plasma arginine quantification at diagnosis, during acute crises, and at 3–6 month intervals during stable management; plasma arginine trending to detect dietary non-compliance or increased protein intake; plasma ornithine — reduced due to impaired recycling; plasma glutamine — moderately elevated as ammonia burden indicator; plasma guanidino compounds — guanidinoacetate, homoarginine, N-alpha-acetylarginine elevated; lysine and other amino acids for dietary adequacy assessment), plasma ammonia records (plasma ammonia — typically moderately elevated 80–200 µmol/L in arginase deficiency; severe acute hyperammonemia unusual but may occur during high-protein loads or severe catabolism; ammonia monitoring at each clinic visit; ammonia trending during acute illness protocols; critical value reporting above 150 µmol/L; ammonia normalization as treatment adequacy criterion), urine amino acid and orotic acid records (urine arginine markedly elevated; urine ornithine reduced; urine orotic acid elevated — the arginine overflow driving pyrimidine synthesis; urine guanidino compounds; urine creatinine for normalization), and arginase 1 enzyme activity records (erythrocyte arginase 1 activity — the most accessible assay; very low or absent enzyme activity in arginase deficiency; enzyme activity in homozygous and compound heterozygous patients; enzyme activity in heterozygous carriers — intermediate activity; enzyme activity as functional complement to molecular diagnosis; erythrocyte arginase activity monitoring on treatment to confirm assay reliability) — at a 1-minute interval during laboratory hours. Alert immediately.
Molecular Genetics — ARG1 Variant Identification and Family Cascade
Monitor ARG1 gene sequencing and deletion/duplication records (comprehensive ARG1 gene sequencing — over 60 pathogenic variants catalogued; deletion/duplication analysis by MLPA for large rearrangements; variant classification by ACMG criteria; missense variants in the conserved Mn2+-binding active site residues common; the p.Trp122Stop, p.Arg21Gln, and other recurrent variants; genotype-phenotype correlation — limited, with the same variant producing variable spasticity severity across families; pathogenic variant confirmation in a second reference laboratory when clinical presentation atypical), family cascade evaluation records (autosomal recessive inheritance with 25% sibling recurrence risk; first-degree sibling testing with plasma arginine and ARG1 molecular testing after proband variant identification; erythrocyte arginase activity as rapid biochemical screen in at-risk siblings; presymptomatic treatment with low-arginine diet and nitrogen scavengers in identified presymptomatic siblings, with evidence suggesting neurological outcome improvement when treatment begins before symptomatic spasticity; parental carrier confirmation; carrier status implications for reproductive counseling), and prenatal and preimplantation genetic testing records (prenatal molecular testing for known familial ARG1 variants; preimplantation genetic testing planning records; neonatal screening — ARG1 deficiency is detectable on expanded newborn screening by tandem mass spectrometry measuring arginine, though with imperfect sensitivity and specificity) — at a 1-minute interval during laboratory hours. Alert immediately.
Dietary Management and Nitrogen Scavenger Therapy
Monitor dietary protein restriction records (natural protein restriction as the cornerstone of arginine lowering — restricted to 0.5–1.5 g/kg/day depending on age, ARG1 residual activity, and tolerance; arginine-free essential amino acid supplement prescription providing protein equivalents without arginine; arginine-free amino acid formula for additional protein intake; dietary arginine avoidance of high-arginine foods — meat, fish, nuts, legumes, dairy; dietary compliance documentation; illness protocol records for anabolic stress prevention during intercurrent illness — reduced protein during illness to suppress catabolism), nitrogen scavenger therapy records (sodium phenylbutyrate (NaPBA) or glycerol phenylbutyrate (GPB) as adjunct nitrogen scavenging; phenylacetylglutamine urine monitoring confirming scavenger efficacy; plasma glutamine on scavenger therapy; sodium benzoate as alternative or adjunct; scavenger dose records; gastrointestinal tolerability; plasma arginine response to scavenger therapy — monitoring to confirm additional arginine lowering beyond diet alone), and nutritional monitoring records (growth anthropometrics at each visit — height, weight, head circumference; albumin and prealbumin for protein nutritional status; zinc, selenium, and essential fatty acid levels; micronutrient panel for deficiencies common on restricted diets; caloric adequacy monitoring; vitamin D status; iron status — low-protein diets can be iron-poor) — at a 1-minute interval during clinical and laboratory hours. Alert immediately.
Neurological Examination, Gait Analysis, and Spasticity Management
Monitor neurological examination records (lower extremity spasticity assessment — Modified Ashworth Scale for hip adductors, knee extensors, and ankle plantarflexors; serial Ashworth scale at each clinic visit; tone distribution mapping; lower extremity reflexes — hyperreflexia and clonus documentation; Babinski sign; upper extremity involvement assessment; bulbar function — speech and swallowing; cranial nerve assessment; sensory examination), gait analysis records (clinical gait observation — scissors gait, toe-walking, steppage; quantitative gait analysis at specialized centers — temporal-spatial parameters, kinematics, kinetics; ambulation status classification — community ambulation, household ambulation, non-ambulatory; functional mobility assessment — Gross Motor Function Classification System (GMFCS); assistive device use records — walker, crutches, wheelchair; ambulation trajectory over time), spasticity pharmacotherapy records (baclofen dose and formulation records; tizanidine dose records; dantrolene records; botulinum toxin injection records — lower extremity muscle selection, dose, injection interval, response assessment; intrathecal baclofen pump implantation records — pump fill and programming records; trial intrathecal baclofen response assessment), and orthopedic surveillance records (hip X-rays for subluxation and dislocation monitoring at annual intervals in non-ambulatory patients; scoliosis screening by spine X-ray; foot and ankle deformity — equinovarus, planovalgus — assessment; orthoses prescription records — AFO, KAFO; surgical intervention records — tendon lengthening, hip stabilization, scoliosis correction; rehabilitation records — physical therapy, occupational therapy, speech therapy) — at a 1-minute interval during clinical hours. Alert immediately.
EEG Monitoring and Seizure Management
Monitor EEG records (baseline EEG at diagnosis for epileptiform activity characterization; EEG during acute episodes for seizure monitoring; interictal EEG for background slowing and epileptiform discharge surveillance at 6–12 month intervals; video-EEG for spell characterization in patients with paroxysmal events of uncertain nature; EEG response to antiepileptic treatment — epileptiform discharge reduction as treatment adequacy surrogate; prolonged EEG monitoring for subclinical seizure detection), seizure diary and antiepileptic therapy records (seizure frequency and semiology documentation; antiepileptic drug dose and formulation records; valproate level monitoring — valproate interaction with nitrogen scavenger therapy; plasma amino acid monitoring on valproate — valproate may impair urea cycle function; levetiracetam level monitoring; adverse effect monitoring for antiepileptic drugs; seizure breakthrough monitoring and dose escalation records; ketogenic diet or modified Atkins diet records in refractory seizures — relevant in arginase deficiency due to protein restriction already in place), and neurological acute assessment records (status epilepticus management records; antiepileptic rescue medication records; acute post-ictal assessment; EEG in the acute setting for nonconvulsive status epilepticus exclusion) — at a 1-minute interval during clinical hours. Alert immediately.
Neuroimaging and Neurodevelopmental Assessment
Monitor brain MRI records (brain MRI at diagnosis for cerebral atrophy, white matter signal abnormalities, cortical thinning, and myelination delay characterization; serial brain MRI at 2–3 year intervals for atrophy progression and white matter disease trajectory; MR spectroscopy for arginine peak in the brain, guanidino compounds, and N-acetylaspartate reduction as neuronal integrity marker; diffusion tensor imaging for corticospinal tract integrity assessment — the primary spasticity-mediating white matter tract; brain MRI volumetry for global and regional atrophy quantification; functional MRI in research settings for motor cortex activation during attempted movement), neurodevelopmental assessment records (IQ and cognitive function testing at annual intervals — Bayley Scales in infants, WPPSI or WISC in children; adaptive behavior scales — Vineland Adaptive Behavior Scales; language assessment — the language development trajectory in arginase deficiency; executive function testing; the neurocognitive trajectory in arginase deficiency is characterized by initial plateau followed by gradual decline without adequate arginine control; pre-treatment cognitive baseline for outcome attribution; educational placement and IEP records; school achievement testing; neuropsychological testing for attention, working memory, and processing speed), and quality of life and functional assessment records (pediatric quality of life measures — PedsQL, CHQ; adult quality of life; activities of daily living assessment — FIM, WeeFIM; caregiver burden assessment; functional communication assessment in patients with dysarthria from spastic bulbar involvement) — at a 1-minute interval during clinical hours. Alert immediately.
Authentication and Clinical Identity
Monitor authentication at 1-minute intervals, 24/7. Arginase deficiency management coordinates across metabolic medicine (plasma arginine, ammonia, and amino acid monitoring; nitrogen scavenger therapy management; dietary protein restriction management), molecular genetics (ARG1 sequencing, erythrocyte arginase activity, family cascade), dietetics (arginine-restricted diet with essential amino acid supplementation, illness protocols), neurology (spasticity pharmacotherapy, seizure management, antiepileptic therapy, EEG monitoring), physical medicine and rehabilitation (gait analysis, GMFCS classification, physical therapy, occupational therapy, adaptive equipment), orthopedics (hip surveillance, scoliosis monitoring, tendon surgery), neurosurgery (intrathecal baclofen pump), neuropsychology (cognitive assessment, educational planning), speech-language pathology (dysarthria, swallowing), ophthalmology (optic atrophy surveillance in patients with significant cerebral atrophy), and neonatal screening programs — authentication failures block the integrated multi-platform care coordination that the progressive neurological disease trajectory, multi-specialty spasticity management complexity, seizure monitoring obligations, and lifelong neurodevelopmental surveillance demands require across this rare but distinctly progressive urea cycle disorder.
SSL Certificates
Monitor SSL certificate expiry across all plasma arginine and amino acid platforms, plasma ammonia platforms, erythrocyte arginase activity assay systems, ARG1 molecular genetics platforms, EEG monitoring systems, brain MRI platforms, gait analysis platforms, spasticity assessment systems, dietary management platforms, nitrogen scavenger therapy monitoring systems, neurodevelopmental assessment platforms, orthopedic imaging systems, and arginase deficiency registry systems. Certificate errors disrupt the integrated multi-platform care infrastructure that arginase deficiency management requires across the progressive neurological disease trajectory, arginine burden monitoring complexity, multi-specialty spasticity management obligations, and lifelong neurodevelopmental surveillance.
HIPAA and Rare Genetic Disease Patient Privacy Considerations
Arginase deficiency technology platforms handle highly sensitive PHI encompassing ARG1 molecular testing results (biallelic variants identifying both parents as obligate carriers, with 25% recurrence risk per pregnancy), erythrocyte arginase enzyme activity records (functional biochemical confirmation of the diagnosis), plasma arginine and ammonia records documenting metabolic burden and dietary compliance (with direct implications for the degree of neurological protection achieved and the prognosis for ambulation and cognitive function), brain MRI reports documenting cerebral atrophy and white matter injury (with direct prognostic implications for cognitive and motor outcomes), EEG records and seizure diary (with implications for driving capacity, employment, and safety), cognitive and adaptive behavior assessment records (IQ scores and functional assessments with implications for educational placement and long-term disability benefit eligibility), gait analysis records and GMFCS classification (documentation of progressive physical disability), spasticity management records (botulinum toxin injections, intrathecal baclofen pump, surgical records), and orthopedic surgical records.
The progressive physical disability of arginase deficiency — the spastic diplegia progression from toe-walking in early childhood to wheelchair dependence in adolescence or early adulthood — creates a unique privacy dimension because mobility status is observable, and the genetic basis of the physical disability creates implications for family members that extend beyond the affected individual. The early-childhood onset of cognitive assessment means that IQ records generated at age 3–4 years may follow individuals through educational, employment, and guardianship proceedings for decades, requiring careful access controls and minimum necessary disclosure practices in neurodevelopmental assessment platforms.
Alerting Strategy for Arginase Deficiency Tech Platforms
Immediate laboratory-hours alerting for plasma arginine and amino acid platforms: Plasma arginine is the primary metabolic monitoring tool in arginase deficiency — the degree of plasma arginine reduction below 200 µmol/L is the most important modifiable determinant of neurological trajectory; failures during monitoring visits delay the detection of dietary non-compliance or inadequate nitrogen scavenger dosing that allows arginine-mediated neurological toxicity to accumulate.
Immediate laboratory-hours alerting for plasma ammonia platforms: Plasma ammonia monitoring is required at each clinic visit and during intercurrent illness in arginase deficiency; though severe acute hyperammonemia is less common than in other urea cycle disorders, ammonia elevation above 150 µmol/L during acute illness requires immediate intervention.
Immediate clinical-hours alerting for neurological examination, gait analysis, and spasticity assessment platforms: Serial neurological examination, Ashworth scale spasticity grading, and gait analysis platforms require immediate alerting during clinical hours for progressive spasticity detection and treatment escalation decision support.
Immediate clinical-hours alerting for EEG monitoring platforms: EEG platforms require immediate alerting during clinical hours for seizure monitoring and antiepileptic management guidance — seizures complicate approximately 40% of arginase deficiency cases and contribute to the cognitive decline trajectory.
Immediate clinical-hours alerting for neuroimaging platforms: Brain MRI platforms require immediate alerting during clinical hours for cerebral atrophy and white matter disease trajectory documentation guiding treatment intensity.
Sustained-failure alert (10–15 minutes): ARG1 molecular genetics platforms, erythrocyte arginase activity platforms, dietary management records systems, nitrogen scavenger therapy monitoring platforms, neurodevelopmental assessment platforms, gait analysis systems, orthopedic imaging platforms, intrathecal baclofen pump records systems, family cascade evaluation platforms, prenatal and preimplantation genetic testing platforms, and arginase deficiency registry data transfer platforms.

Conclusion
Arginase deficiency technology platforms are embedded in clinical decisions where plasma arginine monitoring platform availability for a 5-year-old with arginase deficiency on sodium phenylbutyrate and arginine-restricted diet — when the platform required to report the plasma arginine of 380 µmol/L (above the 200 µmol/L neurological toxicity threshold) that will trigger a dietary protein review, glycerol phenylbutyrate dose increase, and discussion with the family about the arginine-rich foods that have been introduced during the school lunch program returns an error and the treating metabolic physician cannot confirm whether the arginine lowering strategy is protecting the corticospinal tracts from ongoing arginine neurotoxicity — creates a monitoring gap during which plasma arginine elevation persists at neurotoxic levels and the spasticity that will eventually progress to wheelchair dependence continues to accumulate irreversibly in the lower extremity motor pathways; where neurological examination and gait analysis platform availability for a 9-year-old with arginase deficiency — when the platform delivering the Modified Ashworth Scale documentation showing a progression from grade 2 to grade 3 hip adductor and knee extensor spasticity that will trigger a botulinum toxin injection referral and intrathecal baclofen evaluation is unavailable during the neurology clinic visit — results in a missed clinical decision point for a child whose window for ambulatory preservation is narrowing each month the spasticity goes ungraded and untreated; and where EEG monitoring platform availability for a 12-year-old with arginase deficiency and newly reported nocturnal convulsive episodes — when the platform delivering the overnight video-EEG that reveals generalized spike-wave complexes consistent with a new onset juvenile myoclonic epilepsy superimposed on the chronic epileptiform background requires immediate antiepileptic drug initiation is unavailable during the epilepsy monitoring study — delays the seizure characterization that determines whether valproate (which may impair urea cycle function in the context of arginase deficiency) or levetiracetam is the appropriate first antiepileptic agent. A plasma arginine monitoring platform unavailable when arginine is rising above the neurotoxic threshold and the neurological damage that will define the patient's motor and cognitive future is accumulating, a gait analysis platform down when the spasticity progression decision point for botulinum toxin or intrathecal baclofen is being missed, an EEG platform unavailable when a seizure disorder is newly manifesting on top of the chronic arginine neurotoxicity — these are not IT incidents. They are clinical crises in the management of a urea cycle disorder whose defining natural history is not episodic hyperammonemic coma but the slow, progressive, potentially preventable neurological destruction from chronic arginine accumulation that determines whether a child with arginase deficiency will walk independently as an adult or require a wheelchair — a determination that is made, year by year, in the quality of the plasma arginine monitoring, the consistency of the neurological assessment, and the reliability of the multi-specialty spasticity management infrastructure.
