overall_neuropathy_limitations_scale: Overall Neuropathy Limitations Scale (ONLS)

Description

Calculates the ONLS score to assess disability in patients with immune-mediated peripheral neuropathies (e.g., GBS, CIDP). The scale consists of an Arm Scale (0-5) and a Leg Scale (0-7), summed for a total score of 0-12.

Usage

overall_neuropathy_limitations_scale(arm_symptoms, wash_hair, turn_key,
                                     use_knife, fasten_buttons, leg_symptoms,
                                     walking_status)

Value

A list containing:

ONLS_Total_Score

The calculated total score (Range 0-12).

Arm_Scale_Score

The arm subscore (0-5).

Leg_Scale_Score

The leg subscore (0-7).

Arguments

arm_symptoms

Numeric (0 or 1). Does the patient have symptoms in hands or arms (e.g., tingling, numbness, weakness)? (1 = Yes).

wash_hair

Numeric (0, 1, or 2). Ability to wash and brush hair. 0: Normal, 1: Difficulty, 2: Impossible.

turn_key

Numeric (0, 1, or 2). Ability to turn a key in a lock. 0: Normal, 1: Difficulty, 2: Impossible.

use_knife

Numeric (0, 1, or 2). Ability to use a knife and fork together. 0: Normal, 1: Difficulty, 2: Impossible.

fasten_buttons

Numeric (0, 1, or 2). Ability to fasten buttons or zips. 0: Normal, 1: Difficulty, 2: Impossible.

leg_symptoms

Numeric (0 or 1). Does the patient have symptoms in legs or feet? (1 = Yes).

walking_status

String. Functional status of walking/running. "normal": No problems (Score 0 if no symptoms, 1 if symptoms). "symptoms_only": Symptoms present but walks/runs normally (Score 1). "difficulty_running": Difficulty running or abnormal gait but does not require support (Score 2). "difficulty_walking": Difficulty walking (gait abnormalities/reduced distance) but independent (Score 3). "unilateral_support": Uses 1 stick/cane/crutch (Score 4). "bilateral_support": Uses 2 sticks/crutches or a frame (Score 5). "wheelchair": Uses a wheelchair (Score 6). "bedbound": Restricted to bed (Score 7).
