This is a multicenter observational study aimed to characterize multi-muscle synergy organization in relation to postural stability in individuals with Peripheral Neuropathies (PN) compared to healthy age-matched subjects and to assess the effectiveness of a rehabilitation program driven by multi-muscle synergy organization.
This is a multicenter observational study of peripheral neuropathies patients aiming at characterizing multi-muscle synergy and at assessing the effectiveness of a rehabilitation program driven by multi-muscle synergy organization. The study can be divided in two phases: Phase 1 will included peripheral neuropathies patients and healthy age-matched subjects. Peripheral neuropathies patients will be assessed with: * Neurological assessment formalized via Total Neuropathy Score-clinical version (TNSc©) * Nerve conduction studies * Impact of PN on patients' quality of life using Short Form Health Survey 36 (SF-36) * Functional status using Functional Independence Measure (FIM) Peripheral neuropathies patients and healthy age-matched subjects will receive a postural evaluation recording during three different postural tasks (quiet standing, voluntary sway and shoulder flexion): * centre of pressure (COP) displacement of force platform; * surface muscle activation using electromyography (EMG) of 13 muscle on the right side of the body (tibialis anterior, soleus,gastrocnemius lateralis-medialis, biceps femoris, semitendinosus, rectus femoris, vastus lateralis and medialis, tensor fasciae latae, lumbar and thoracic erector spinae and rectus abdominis). Phase 2 will included only peripheral neuropathies patients. Participants will be assessed at baseline, after a 20 session 2-3/w program of physical therapy and at a follow up of 3 months. The evaluations of the first phase will be implemented with evaluation of mobility and balance using Six Minute Walking Test (6MWT), Mini Balance Evaluation System Test (MiniBESTest) and Timed Up and Go test (TUG).

RECRUITINGEvaluation of multi-muscle synergy organization using Synergy Index (SI)
Multi-muscle Synergy Index (SI) are new measurements of postural stability and a proxy of multi-muscle coordination. Synergy has been defined as a neural organization of a large set of effectors (e.g., muscles) providing stability of salient performance variables (e.g., center of pressure, COP). Within this framework, SI has been introduced, reflecting the relative amount of inter-trial variance that does not affect a performance variable.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of change in Anticipatory Synergy Adjustments (ASA)
ASAs represent changes in an index of a multi-muscle synergy stabilizing the coordinate of the center of pressure (COP). Such changes may be seen in young, healthy persons about 200-300 ms prior to the action initiation.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of balance
Evaluation of balance using Mini Balance Evaluation System Test (MiniBESTest). Each item is scored on a 0-4 scale; the scores are summed to obtain a total score of 28. The item are divided in four sessions: anticipatory, reactive postural control, sensory orientation, dynamic gait.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of balance
Evaluation of balance using Timed Up and Go test (TUG). It is a measure of the time taken by the patient for rising from a chair, walking three meters, turning and walking back to the chair to sit down.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of mobility
Evaluation of mobility using Six Minute Walking Test (6MWT). The 6MWT assesses distance walked over six minutes as a sub-maximal test of endurance/aerobic capacity.

Severity of chemotherapy induced-peripheral neuropathy
Total Neuropathy Score-clinical version (TNSc©)

Evaluation of change in electromyography (EMG) parameters
Evaluation of sensory conduction velocity of ulnar, radial and sural nerves.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of change in electromyography (EMG) parameters
Evaluation of motory conduction velocity of ulnar, radial and peroneal nerves.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Impact of PN on patients' quality of life
Evaluation of quality of life using the Short Form Health Survey 36 (SF-36). It is a self-report measure of functional health and well-being. The SF-36 questionnaire consists of eight scales yielding two summary measures: physical and mental health. The physical health measure includes four scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items).
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
Evaluation of change in level of disability
Evaluation of level of disability using Functional Independence Measure (FIM). It is an 18-item, seven-level, ordinal scale intended to be sensitive to changes over the course of a comprehensive inpatient medical rehabilitation program.It includes measures of independence for self-care, including sphincter control, transfers, locomotion, communication, and social cognition.
Time frame: At baseline, after the 20th session of the rehabilitation program, follow up at 3 months
