3D Printers for Autonomy in the Care of Inpatients in Continuing and Rehabilitation Care

Patients hospitalized in CRCU will be informed of the research. Those who do not object to participating in the research and who meet the eligibility criteria will be included.

Their participation will begin with an initial functional and joint assessment of the patient's hand by an occupational therapist to determine the diameter of cutlery handles best suited to the patient's grip (25, 30, 35 or 40 mm).

The patient's autonomy ("Eating" criterion on the Katz scale) will be assessed by the same ergotherapist, and the quantity of food ingested will be measured by a dietician at 3 points:

• During a lunch before using the adapted cutlery handles (Day0);
• At lunch when the adapted cutlery handles are used for the first time (Day1);
• At lunch after 3 days' use of the adapted cutlery handles (Day3), corresponding to the learning phase in the use of the technical aid.

Lunches will be similar over the 3 days. These are standard lunches predefined by the unit's dietician.

On Day0 and Day3, the ergotherapist will carry out an ecological assessment of meals. Ecological assessment is used in ergotherapy to observe and analyze the patient's interactions with his environment and their repercussions on his ability to perform a task. The aim here is to assess whether the patient exhibits compensation of the upper limb (such as shoulder elevation or trunk inclination) during the meal performed without technical aids (Day0) and that performed after the learning phase of using the adapted handle (Day3).

The patient's participation will end at the end of the Day3 assessments.

Inclusion criteria

• Patient hospitalized in a Continuing Care and Rehabilitation department ;
• Patient suffering from a neurodegenerative disease (Mini Mental Test score > 15);
• Age ≥ 18 years;
• Patient with a score ≥ 3 on the "Eating" criterion of the Katz scale (corresponding to the need for at least partial assistance with meals).

Exclusion criteria

• Opposition of the patient or his relatives to participating in the research ;
• Patient unable to use hands to eat (amputation, paralysis, etc.);
• Patient under court protection;
• Pregnant, parturient or breast-feeding woman;
• Any other reason which, in the opinion of the investigator, could interfere with the evaluation of the study objectives.
