An Innovative Proprioceptive Instrument for Upper Extremities

18. August 2026 aktualisiert von: National Cheng-Kung University Hospital

Development, Validation, and Clinical Application of an Innovative Proprioceptive Instrument for Upper Extremities: PropArm-PosiMoF (PropArm)

This study aimed to develop and validate an innovative proprioceptive assessment instrument for the upper extremities, the PropArm-PosiMoF (PropArm). This observational study was conducted in three stages. The first stage focused on the development and validation of PropArm, including test-retest reliability, concurrent validity, and convergent validity. The second stage established age norms and cut-off points in healthy adults. In the final stage, PropArm was applied to patients with proprioceptive impairments (stroke, shoulder impingement syndrome, and diabetes mellitus patients) to examine its diagnostic accuracy and clinical applicability.

Studienpopulation

The study population includes healthy young adults (20-29 yr), healthy adults (30-39, 40-49, and 50-59 yr), healthy older adults (60-69, 70-79, and 80-89 yr) across different age groups, and patients with stroke, shoulder impingement syndrome, or diabetes mellitus. Participants are right-hand dominant and able to follow verbal instructions without cognitive impairments.

  6. Diabetes (DM):

Inclusion Criteria:

  • (1) Age between 20 and 89 years,
  • (2) Diagnosis of diabetes mellitus by a specialist physician, based on one of the following:

    1. Fasting plasma glucose (FPG) ≥ 126 mg/dL or 7.0 mmol/L;
    2. Hemoglobin A1C (HbA1c) ≥ 6.5%;
    3. Plasma glucose ≥ 200 mg/dL or 11.1 mmol/L at 2 hours during an oral glucose tolerance test (OGTT);
    4. Presence of hyperglycemia symptoms (polyphagia, polyuria, polydipsia, and unexplained weight loss) with a random plasma glucose ≥ 200 mg/dL.

Diagnosis of diabetes is confirmed if any two of items (a-c) are met, or if any one of them remains positive on repeat testing; fulfillment of item (d) alone is also sufficient for diagnosis.
