Can a device that stimulates cell activity using radio electric emissions improve recovery from traumatic joint injuries?

Time to healing, with healing assessed using the following assessments by the medical practitioner and subjective assessments of the patient at the first clinical examination, within 4 days after the trauma/accident (T0); immediately after the administration of the Neuro Postural Optimization (NPO) treatment, which is the one-session treatment delivered on the subject’s ear (T1); at the end of the 18th session of Tissue Optimization (TO) treatment (T2); at the 30 day-follow up (T3):
Medical assessments:
1. Functional dysmetria. The evaluation of dysmetria is an evaluation of neurological semiology aimed at observing the presence of a dysfunction. Evaluation of dysmetria in the lower limbs can be evidenced, by lightly and symmetrically placing the operator's hands on the femoral quadriceps of the subject being examined in supine position, taking care that the nails of the two left and right thumbs are perfectly aligned. Asking the subject to move from the supine to the sitting position, a progressive misalignment of the two thumbs is highlighted. This manoeuvre allows the operator to perceive and highlight the asymmetric activation of symmetrical muscle groups (dysmetria), such as the quadriceps muscles. In this study, we observed the presence or absence of the phenomenon before (T0) and after NPO treatment (T1).
2. Joint swelling assessment using the scale none (1), little (2), very (3), very much (4)
3. Perception of pain caused during orthopaedic assessment manoeuvres assessed using the scale none (1), little (2), very (3), very much (4)
4. Assessment of patellar ballottement. The procedure to assess patellar ballottement requires that the patient be placed in the supine position with leg straight. The examiner applies anterior to posterior pressure over the patella, and gently oscillates the patella, palpating for motion. Increased motion or spongy joint feel means intra-articular knee swelling. The scale none (1), little (2), very (3), very much (4), was used to assess the patellar ballottement.
5. Valgus Stress Test. There are two versions of this test, valgus at 0 degrees and valgus at 30 degrees. When tested at 0 degrees, the MCL, medial joint capsule, and anterior and posterior cruciate ligaments are stressed. When tested at 30 degrees, the MCL is the primary stabilizer. A positive test occurs when pain or gapping is produced. The following scale was used to assess the increased motion: none (1) = level 1: 0-5 mm of joint opening, no instability; little (2) = level 2: 5-10 mm of joint opening, mild instability; very (3) = level 3: 10-15 mm of joint opening, moderate instability; very much (4) = level 4, >15 mm of joint opening, severe instability.
6. Knee flexion angle measured in degrees with Ortho physical lite, a knee goniometer app installed in an Apple iPhone 6s

Patient's subjective assessments assessed using a questionnaire with items scored using the scale none (1), little (2), very (3), very much (4):
7. Functional impotence
8. Pain
9. Feeling of stiffness
10. Feeling of knee instability
11.Instability to monopodal load

Pain reduction in post-traumatic second and third-degree lesions of the medial collateral ligament of the knee evaluated with verbal analogue scale none (1), little (2), very (3), very much (4) at the first clinical examination, within 4 days after the trauma/accident (T0); immediately after the administration of the Neuro Postural Optimization (NPO) treatment, which is the one-session treatment delivered on the subject’s ear (T1); at the end of the 18th session of Tissue Optimization (TO) treatment (T2) and at the 30 day-follow up (T3)
