Rare Disease Registry Database for Movement Disorders in Southern Anhui Province (W-MoSCA)

October 22, 2026 updated by: First Affiliated Hospital of Wannan Medical College

According to the World Health Organization (WHO) definition, a rare disease is a disease affecting fewer than 6.5 people per 10,000; in China, it generally refers to diseases with a prevalence of less than 1/10,000 (i.e., with a total of no more than 140,000 patients). Such diseases are mostly hereditary or congenital in origin. Patients with rare diseases often present with complex symptoms, most of which are neurological. Although a large number of rare diseases have been identified, the small number of patients with each disease and the diversity of symptoms make early diagnosis difficult and render large-sample clinical trials challenging. Consequently, most rare diseases lack curative treatments; available therapies are of limited efficacy or prohibitive cost, ultimately leading to severe disability or death and imposing a substantial socioeconomic burden. This study establishes a registry for motor neuron diseases (MND), spinocerebellar ataxias (SCAs), hereditary muscular dystrophy (HMD), and hereditary spastic paraplegia (HSP). Owing to the low incidence, complex clinical diagnosis, unclear pathogenic mechanisms, and strong genetic heterogeneity, epidemiological data on rare motor neuron diseases are limited, further increasing the difficulty of biomarker screening and targeted therapeutic development. Therefore, there is an urgent need to establish a comprehensive registry and to obtain reliable evidence on risk factors and early diagnosis through research. This study aims to establish a registry of rare neurological diseases in the southern Anhui Province and to build a high-quality biobank of human biological resources.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

These rare movement-related neurological diseases are all characterized primarily by gait abnormalities; although muscle weakness, ataxia, poor muscle endurance, and spastic paraplegia are their typical presentations, respectively, they share overlapping motor neurological symptoms and similar early clinical manifestations.

Description

Inclusion Criteria:

  • Adults aged 19 years or older who are capable of giving informed consent.
  • Definitive diagnosis of one of the following diseases: (1) amyotrophic lateral sclerosis (diagnosed according to the revised El Escorial criteria, Awaji criteria, or Gold Coast criteria); (2) spinocerebellar ataxia; (3) muscular dystrophy; (4) hereditary spastic paraplegia.
  • Others: primary lateral sclerosis, progressive muscular atrophy, ALS-FTD syndrome, progressive bulbar palsy, benign focal muscular atrophy, and other motor neuron diseases.

Exclusion Criteria:

  • Patients with concomitant systemic diseases;
  • Vulnerable research subjects: minors and patients with cognitive impairment;
  • Participants from whom clinical information and human biological samples cannot be collected;
  • Other patients judged by the investigators to be unsuitable for participation in the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Amyotrophic Lateral Sclerosis Functional Rating Scale (K-ALSFRS-R)
Time Frame: through study completion, an average of 3 months

Total score: 0 to 48 points 48 points: completely normal function 0 points: complete loss of function in the corresponding dimension. The lower the score, the more severe the functional disability.
through study completion, an average of 3 months
Hereditary spastic paraplegia (HSP): Spastic Paraplegia Rating Scale (SPRS)
Time Frame: through study completion, an average of one year

Including 13 items, each item is scored from 0 to 4 (0 = normal, 4 = most serious impairment) Total score: 0 to 52 points; the higher the score, the more serious the condition
through study completion, an average of one year
Scale for the Assessment and Rating of Ataxia (SARA)
Time Frame: through study completion, an average of one year

Including 8 items, each item has a different maximum score. Total score: 0 to 40 points; the higher the score, the more severe the ataxia. 0 points: no ataxia. 40 points: the most severe ataxia.
through study completion, an average of one year
6-minute walk test for hereditary muscular dystrophy
Time Frame: through study completion, an average of 1 year

The subjects walked continuously for 6 minutes as fast and safely as possible in a flat hard corridor; they can use the patient's daily walkers, crutches, and orthopedic braces; they are allowed to stop and rest in the middle (timer does not stop), and the total walking meters PMC is recorded at the end of 6 minutes.
through study completion, an average of 1 year
