Does the use of the medical device in the treatment of musculoskeletal disorders lead to an improvement ? Participants will use the medical device, which provides electrical stimulation, biofeedback and pressure biofeedback to re-educate the muscles of the knee and spine area and

Description:

Rational : Today, musculoskeletal disorders (MSDs) are considered to be one of the world's leading pathologies. They are also the most widespread occupational pathology in Europe. MSDs include a variety of conditions affecting bones, joints, muscles and connective tissues. To treat these disorders, the guidelines recommend non-drug therapies as first-line treatments for chronic low-back pain and osteoarthritis pain, such as electrostimulation and biofeedback therapy. In this context, the promoter wishes to carry out this study in order to reinforce the data currently available on the medical device PHENIX LIBERTY. Design: Prospective, interventional with non invasive and non burdensome procedure, non-comparative, multicenter, open-label study of a CE-marked medical device Intervention : As part of this clinical investigation, the medical device under investigation is used in accordance with its usual use, and the patient's therapeutic procedure includes additional, non-invasive procedures. These additional procedures relate to the addition of an end-of-life visit and validated questionnaires assessing functional deficiencies and impact on daily life. The care will be conduct as follow: - 1 inclusion visit (V0) (from 1 say to 15 days prior the the first functionnal therapeutic re-education session) - 12 sessions of functional therapeutic re-education, during which the PHENIX LIBERTY device may be used. Sessions performed at regular intervals according to a schedule drawn up by the physiotherapist (between 6 and 8 weeks); - 1 end visit (V13), 1 week after the 12th session to complet questionnaires In total, the patient will be followed 11 weeks maximum

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean change in Lower Extremity Functional Scale (LEFS) score on the impact of locomotor disorders of the knee	The Lower Extremity Functional Scale (LEFS) is used by physiotherapists and occupational therapists in many clinical settings. It is an English-language measurement tool that collects psychometric data and assesses the functional status of the lower limbs. It consists of 20 questions on the level of difficulty experienced during everyday activities.	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Primary	Mean change in the Oswestry Disability Index (ODI) score for the impact of locomotor disorders of the spine.	The ODI will be used to assess the disability caused by Lower Back Pain (LBP); The Oswestry Disability Index (ODI), a patient-completed questionnaire that gives a subjective percentage score of the level of function (disability) in activities of daily living in people undergoing rehabilitation after low back pain. The questionnaire examines the level of disability in 10 activities of daily living. Each item consists of 6 statements rated from 0 to 5. With 0 indicating the lowest level of disability and 5 the highest, the total score is calculated as a percentage, with 0% indicating no disability and 100% indicating the highest level of disability.	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Change in patients' visual analog scale (VAS) pain scores for knee pain and/or spine pain at rest and on palpation	The pain caused by the TMS of the knee and/or the spine will be assessed by the Visual Analogue Scale (VAS).; The VAS is made up of a 10-centimeter line anchored by two ends of the pain. 10 is the first end being the "maximum pain imaginable" and 0 is the other end being "no pain"	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Trends in consumption of painkillers and anti-inflammatories	Rate of consuption of painkillers and anti-inflammatories	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes in the rate of improvement of hypertonia of the concerned area (knee or spine) through measurement of myoelectric activity	A surface Electromyography (EMG) will be used. Muscle electrical activity provides a "map" of muscle recruitment according to exercise conditions (position, relative load, type of resistance, type of support, etc.).	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes in the rate of improvement of hypertonia of the concerned area (knee or spine) through Oxford Grading Scale	The Oxford scale is commonly used to manually assess muscle strength, and can help diagnose problems in which weakness plays a role. According to the Oxford scale, muscle strength is rated from 0 to 5 (0 being no muscle contraction > 5 being movement through a full range against full resistance). Scoring is as follows: 0 ? No visible or palpable contraction, 1 ? Visible/palpable muscle contraction but no movement, 2 ? Movement across full range with gravity eliminated (low strength), 3 ? Movement across full range against gravity only (fair strength), 4 ? Movement across full range against gravity with some resistance (good strength), 5 ? Movement across full range against gravity with full resistance (normal strength).	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes in the rate of improvement in awakening and muscle strengthening through Oxford grading scale	The Oxford scale is commonly used to manually assess muscle strength, and can help diagnose problems in which weakness plays a role. According to the Oxford scale, muscle strength is rated from 0 to 5 (0 being no muscle contraction > 5 being movement through a full range against full resistance). Scoring is as follows: 0 ? No visible or palpable contraction, 1 ? Visible/palpable muscle contraction but no movement, 2 ? Movement across full range with gravity eliminated (low strength), 3 ? Movement across full range against gravity only (fair strength), 4 ? Movement across full range against gravity with some resistance (good strength), 5 ? Movement across full range against gravity with full resistance (normal strength).	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes in the rate of improvement in awakening and muscle strengthening through measurement of myoelectric activity	A surface Electromyography (EMG) will be used. Muscle electrical activity provides a "map" of muscle recruitment according to exercise conditions (position, relative load, type of resistance, type of support, etc.).	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes of microcirculation of the concerned spine area	Assessment on the basis of clinical palpation examination done by the practitioner	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes of the microcirculation of the concerned knee area	The measurement of the muscular perimeter around the concerned knee will be assessed by a tape measure	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Changes of the improvement of the motor control through the measurement of myoelectrical activity	A surface Electromyography (EMG) will be used. Muscle electrical activity provides a "map" of muscle recruitment according to exercise conditions (position, relative load, type of resistance, type of support, etc.).	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Change in patient's quality of life	The SF-36 will be used to assess the quality of life score.; The SF-36, as described in the name, is a 36-item patient-reported questionnaire that covers eight health domains: physical functioning (10 items), bodily pain (2 items), role limitations due to physical health problems (4 items), role limitations due to personal or emotional problems (4 items), emotional well-being (5 items), social functioning (2 items), energy/fatigue (4 items), and general health perceptions (5 items). Scores for each domain range from 0 to 100, with a higher score defining a more favorable health state.	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Pecentage of patients with an improvement in locomotor disorders	This outcome will be assessed according to the practitioner's opinion. Does the practitioner think that an improvement has been observed --> Yes / No ?	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Incidence of adverse events	Rate of the incidence of adverse events related to the medical device	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
Secondary	Evaluation of responses to the patient satisfaction questionnaire on the use of the PHENIX LIBERTY device after therapeutic management	The satisfaction questionnaire is constructed on the basis of the Likert Scale. The sponsor has written an questionnaire regarding the use of the Phenix Liberty for the patient. The Likert scale (or attitude scale) is a semantic rating system, generally consisting of 5 or 7 items, used in surveys to measure and evaluate perceptions, attitudes and opinions. The evaluation will be based on the following responses: Strongly agree (=5) ; Agree (=4) ; Rather agree (=3) ; Rather disagree (=2) ; Disagree (=1= ; Strongly disagree (=0). The minimum score 0 means a worse outcome and the maximum score 5 means a better outcome.	At Day 0 and Week 11 (at the end visit within the week after the 12th seance)
