Study Description

Brief Summary

The project aims to investigate the validity, and reliability of outcome measures of muscle strength, functioning (gait, balance, and fine motor skills), physical activity, and patient-reported outcome measures of functioning (gait, balance, and fine motor skills), and daily living among patients with polyneuropathy. Further, the project aims to compare physical activity and patient-reported outcome measures of functioning (gait, balance, and fine motor skills), and daily living among patients with polyneuropathy with physical activity and patient-reported outcome measures of functioning (gait, balance, and fine motor skills) and daily living in healthy adults.

Condition or Disease	Intervention/Treatment	Phase
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) Vasculitic Neuropathy POEMS Syndrome Multifocal Motor Neuropathy Charcot-Marie-Tooth hATTR Amyloidosis Diabetic Polyneuropathy Idiopathic Neuropathy Polyneuropathies	Other: Validity and reliability of outcome measures in polyneuropathy Other: Healthy controls

Detailed Description

In four phases the investigators will evaluate physical activity and the validity, reliability, and responsiveness of the outcome measures in patients with polyneuropathy. During the four phases clinical outcome measures, patient-reported outcomes measures, and accelerometer data on physical activity will be evaluated. The investigators plan to include 400 adult patients with polyneuropathy (acquired, hereditary, and idiopathic) from our clinic and 120 adult healthy controls. The 400 patients with polyneuropathy include the following subtypes of polyneuropathy: Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), vasculitis polyneuropathy, Polyneuropathy-Organomegaly-Endocrinopathy-Monoclonal protein-Skin changes (POEMS syndrome), Multifocal Motor Neuropathy (MMN), Charcot Marie Tooth (CMT), hATTR amyloidosis, Diabetic Polyneuropathy (DPN), and idiopathic neuropathy.

Arms and Interventions

Arm	Intervention/Treatment
Patients with polyneuropathy Adults (> 18 years) diagnosed with polyneuropathy	Other: Validity and reliability of outcome measures in polyneuropathy Patients will be tested, answer patient reported outcome measures, and wear accelerometer at baseline after 2-4 weeks and after 1-2 years.
Healthy controls Healthy adults (>18 years)	Other: Healthy controls Healthy controls will be tested, answer patient reported outcome measures, and wear accelerometer at baseline visit. There is no follow-up in the healthy control group.

Outcome Measures

Primary Outcome Measures

10-meter Walk Test [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
The patient is asked to 10 meter as fast as possible
Six Spot Step Test [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
The patient is instructed to walk 5 meters as fast as possible, while kicking five cylinder blocks out of five circles marked on the floor.
6-minute Walk Test [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
The patient will be asked to walk back and forth along a 25 meter walkway for six minutes. They will be instructed to walk as far as possible for six minutes.
30 seconds Chair Stand Test [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
The patients will be asked to stand up and sit down as many times as possible in 30 secs with their arms across their chest
Dynamic Gait Index [At baseline, after 2-4 weeks, and after 1-2 years]
The patient will be asked to walk while performing different tasks (walking: normally, while changing speed, while turning head (vertical and horizontal), while turning around, while stepping over obstacles, and walking stairs).
Nine Hole Peg Test [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Fine motor skills
Jamar Hand-grip dynamometer (hand-grip-strength) [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Best of three values
Isometric strength measured with hand-held dynamometer [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Will be tested bilateral at ankle, knee, wrist and elbow
Isokinetic muscle strength measured with Biodex System 3 or 4 PRO, Biodex Medical Systems [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Will be tested bilateral at ankle and knee
SENS motion activity sensor (accelerometer) [At baseline (study entry), and after 1-2 years]
The SENS motion activity sensor is a wearable accelerometer. It measures physical activity by collecting raw data of accelerations. Data on active time, sedentary time, time spent walking and number of steps taken will be collected. The sensor will be attached and worn 24/7 (the sensor will be worn the week following baseline tests, and the week after tests at visit three (1-2 years after baseline).
Inflammatory Neuropathy Cause and Treatment (INCAT) [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Interview based disability scale INCAT evaluates disability of the upper and lower limb. The total INCAT score ranges from 0-10 (low scores indicating no disability and higher scores indicating higher level of disability).

Secondary Outcome Measures

Rasch-build Overall Disability Scale for Immune-mediated peripheral neuropathies (I-RODS) [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
I-RODS is a 24-item patient reported outcome measure that measures disability. The raw score ranges from 0-48, with 0 indicating severe disability and higher scores indicating lower levels of disability.

Assesses limitations related to fear of falling. FES-I is a 16-item patient reported outcome measure that measures fear of falling. The score ranges from 16-64, with higher scores indicating greater fear of falling.
Composite Autonomic Symptom Score (COMPAS-31) [At baseline (study entry), after 2-4 weeks, and after 1-2 years]
Assesses autonomic dysfunction Compass-31 is a patient reported outcome measure that measures autonomic dysfunction. Scores ranges from 0-100, with higher scores indicating more severe symptoms of autonomic dysfunction.
