Tendinopathy
Conditions
Interventions
The 66 participants of the present research will be distributed randomly in two groups: application of an exercise program plus active therapeutic ultrasound (TUS) (N = 33) or application of the same
each phase containing 2 weeks of duration.
The sessions will be performed individually and in a standard-way, with individuals in shorts that keep their knees uncovered. The sessions will be supervise

Eligibility
Age
18 Years to 40 Years
Inclusion criteria
Inclusion criteria: Volunteers of both sexes; with diagnosis of unilateral or bilateral patellar tendinopathy; aged between 18 and 40 years-old; with localized pain at the inferior patellar pole/superior aspect of patellar tendon when perform single leg decline squat, jumping, landing, running, abruptly changing direction and with a score of less than 80 on the Victorian Institute of Sports Assessment - Patella (VISA-P) questionnaire.
Exclusion criteria
Exclusion criteria: Participants will be excluded if they present a history of nervous and/or musculoskeletal injuries in the low back spine and/or lower limbs in the last 6 months, signs and/or symptoms of other diseases and/or another disorders affecting the knees, including systemic and rheumatic diseases and/or pre-existing dysfunctions (clinically evaluated and detected), previous history of knee or patellar tendon surgery, use of intra-articular medications in the knee in the last 6 months, or pregnancy.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pain intensity will be measured using the Visual Analogue Scale (VAS). This outcome will be collected at baseline evaluations (T0), post-8 sessions - 4 weeks (T1) and post-16 sessions - 8 weeks (T2) and at each treatment session. Reductions of 3.0 points in the VAS, will demonstrate possible effectiveness of the program proposed in this study. Functional impairment will be assessed with the VISA-P questionnaire. This outcome will be collected at baseline evaluations (T0), post-8 sessions - 4 weeks (T1) and post-16 sessions - 8 weeks (T2), post-3 months of protocol concluded (T3) and post-6 months of protocol concluded (T4). The effectiveness will be demonstrated if changes of 13 points will be detected. | — |
Secondary
| Measure | Time frame |
|---|---|
| Pain will also be measured with pain pressure threshold; performed in all sessions and also in the evaluations: T0, T1 and T2; increases in the amount of force applied to the patellar tendons, will show improvement. The thermography of the painful sites of the patellar tendons will be evaluated with the thermographic camera; will be performed in the evaluations (T0, T1 and T2) and at each treatment session; the detection of changes in temperature will be influenced by the application of therapeutic ultrasound. The possible tissue changes of the patellar tendons will be evaluated by magnetic resonance imaging (MRI) at two different moments: pre-participation in the study (T0; initial MR) and after the treatment program (T2; final MR). The presence of reduction of intra-tendinous involvement, extent of involvement, tendon volume, tendon cross-sectional area, maximum antero-posterior tendon diameter and signal intensity, will represent tendon tissue improvement. Furthermore, biomechanical patterns of the trunk, hips, knees and ankles will also be collected with kinematic analysis in 2 dimensions. This outcome will be collected at baseline evaluations (T0), post-8 sessions - 4 weeks (T1) and post-16 sessions - 8 weeks (T2). Increases in knee flexion during performance of the functional tests (step down, drop test and one leg single hop test), will show a improvement in the functional / biomechanical pattern. The level of physical activity will be collected with the short version of the International Physical Activity Questionnaire (IPAQ). This outcome will be collected at T0, T1, T2, T3 and T4 evaluations period. The detections of increase of the level of physical activity, will also be considered as improvement of the functional status. The muscular strength (maximal voluntary isometric contraction) of the gluteus maximus, gluteus medius, quadriceps femoris and triceps surae muscles will be evaluated with a hand dynamometer. This outcome will be collected at T0, T | — |
