Please assess the completion status of the following clinical trial:

Trial Title: Contribution of Near-InfraRed Spectroscopy (NIRS) to the Evaluation of Healing After Amputation of the Leg

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: OTHER
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~All groups:~* Patients who have agreed to take part in the study~* Patients with National Health Insurance cover,~* Patients (men or women aged between 18 and 85 years, presenting unilateral transtibial amputation for PAD.~* Able to understand simple instructions~Procedure 1:~* Stabilized patients with their definitive prosthesis, with no modification of the prosthesis in the previous 3 months and at least 6 months after the amputation.~* Definitive prosthesis with a contact socket.~* Patients able to do a 2-minute walk test.~Procedure 2:~- Patients in the initial phase of post-amputation (temporary prosthesis, rehabilitation) following unilateral transtibial amputation.~Exclusion Criteria:~* Patients without national health insurance cover.~* Patients under guardianship.~* Patients with associated chronic motor deficiency, of a neurological origin (examples: sequelae of stroke, balance and coordination disorders), or osteo-articular disease (examples: knee or hip osteoarthritis), given their secondary functional impact, making it impossible for amputees to walk with a prosthesis.~* Severe medical disorder that significantly impairs functional abilities (severe heart failure, respiratory failure, non-stabilized metabolic disorders, such as progressive kidney failure) and diseases with an impact on short or medium-term survival (progressive neoplastic disease, non-stabilized systemic disease).~* Complications, other than microcirculatory, with the stump, able to affect the use of a contact socket: hematoma, formation of cysts, fluid build-up, calcifications of soft tissues, bone spur, infection (skin, abscess), neurinoma, deterioration of the knee joint of the amputated limb, angle of the tibial cut leading to specifically painful osteo-cutaneous impingement, venous thrombosis, abnormal shape of the stump making it unsuitable for a socket (flexum of the knee, pear shaped stumps or stumps with severe invaginations )...~* Local skin disorders in the measurement zone (summit of the antero-external area) of the stump compromising the quality of the signals picked up by the electrode (NIRS and TcPO2) : severe edema, hyperkeratosis, ulceration, inflammatory and infectious phenomena.
