Descrizione dettagliata
Foot drop is a symptom observed in various pathologies including neuro-muscular pathologies of peripheral or central origin. It is a walking disability, causing a deterioration in the patients autonomy and quality of life.
The current medical strategy focuses on various off-the-shelf or custom made devices, depending on the walking functional impairment and the characteristics of foot deformities.
The objective of this study is to assess the superiority in achieving personal goals (set by the patient and the medical team) according to the GAS scale (Goal Attainment Scaling) while wearing the carbon medical device ankle foot orthosis compared to a standard plastic ankle foot orthosis.

Sperimentale: Self-comparison
Patients will be fitted with 2 types of ankle foot orthoses, alternately, divided into 4 phases, in the following order: Phase A1: Standard Plastic ankle foot orthosis Phase B1: carbon medical device ankle foot orthosis Phase A2: Standard Plastic ankle foot orthosis Phase B2: carbon medical device ankle foot orthosis Each patient is his own comparator. For all patients, the total duration of the study will be the same, and will correspond to 12 weeks. |

Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Comparison of the ability to achieve personal goals while wearing carbon or standard plastic ankle foot orthosis
Lasso di tempo: 3 times a week during 12 weeks
|
Personal goals achievement is evaluated via the Goal attainment scaling (GAS). Before starting the study, three personal objectives are defined according to patients needs and investigator review. Raw scores ranging from -3 (degradation) to +2 (maximum achievement of the objective) are defined: "-3" corresponding to degradation "-2" corresponding to the initial state "-1" corresponding to a partial objective achievement "0" corresponding to the total objective achievement "+1" corresponding to a better objective achievement "+2" corresponding to the maximum objective achievement. The GAS is filled 3 times a week during 12 weeks. |

Comparison of patients mobility while wearing carbon or standard plastic ankle foot orthosis
Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12).
|
Mobility is evaluated via staircase tests: Time (in minutes) to go up and down 10 steps
|
Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12).

Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Walking perimeter is evaluated via the Six-minute walk test (6MWT), that measures the distance (in meters) during a 6 minutes walk.
|
Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|

|
Patient's fatigue perception is assessed by the patient via the Borg Rating of Perceived Exertion (RPE) scale following mobility and walking perimeter tests The effort rating is based on a scale of 6 to 20 (6, which is "no effort", to 20, which is "maximum effort").
|
Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Comparison of patients stability while wearing carbon or standard plastic ankle foot orthosis
Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Patient's stability is assessed by 2 means:
|
Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Comparison of patients disability evolution according to the investigator while wearing carbon or standard plastic ankle foot orthosis
Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Doctors' opinion on the Patients disability evolution is measured by the Clinical Global Impression - Improvement (CGI-I) questionnaire. The scale has 7 levels of answer from "very strongly improved" which is the better outcome (= 1 point) to "very strongly aggravated" which is the worst outcome (= 7 points) .Intermediate levels are: " Significantly improved "(= 2 points) ; " Slightly improved " (= 3 points) ; " No improvement " (=4 points) ; " Slightly worsen " (=5 points) ; " Seriously worsen" ( = 6 points). The highest score corresponds to the most impairment in quality of life. |

Comparison of patients disability evolution according to the patient while wearing carbon or standard plastic ankle foot orthosis
Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Patient's opinion on his disability evolution is measured by the Global Impression of Change (PCI-C). The scale has 7 levels from "no change or condition has got worsed"(worse outcome) to "a great deal better, and a considerable improvement that has made all the difference ( better outcome)". Intermediate levels are: "almost the same, hardly any change at all"; "a little better, but no noticeable change", "somewhat better, but the change has not made any real difference"; "moderately better, and a slight but noticeable change"; "better, and a definite improvement that has made a real and worthwhile difference. |

Lasso di tempo: Visits V0 (Day 0), V1 (between week 2 and 3), V2 (between week 5 and 6), V3 (between week 8 and 9) and V4 (Week 12)
|
Pain level is measured by Visual Analogic Scale (VAS) completed by the patient : 0 corresponds to no pain (better outcome) and 10 to maximum pain (worst outcome). Natural gait and confidence in walking are measured by Visual Analogic Scale (VAS) completed by the patient : 0 corresponds to no natural gait or no confidence (worst outcome) and 10 to better natural gait and better confidence (better outcome). Balance is measured by Visual Analogic Scale (VAS) completed by the patient : 0 corresponds to no balance (worst outcome) and 10 to maximum balance (better outcome). |
