Effectiveness of Two Exercise Protocols in the Treatment of Patients With Patellar Tendinopathy
- Conditions
- Patellar Tendinopathy
- Registration Number
- NCT03196063
- Lead Sponsor
- Universidade Cidade de Sao Paulo
- Brief Summary
Patellar tendinopathy is characterized by anterior pain in the knee, due to the great demand imposed on the extensor mechanism of the knee. Evidence shows that the most appropriate treatment for this condition is the conservative treatment, through strengthening with eccentric exercises. However, a recent editorial proposes a new treatment protocol based on concentric and eccentric exercises, with the initial prescription of isometric exercises. The hypothesis of this study is that the protocol is as good as the eccentric exercises, generating less pain.

- Primary Outcome Measures
Name Time Method Pain intensity during rest 8 weeks after randomization This outcome will be evaluated by an 11-point scale ranging from 0 to 10, in which 0 represents "no pain" and 10 represents "pain as bad as it could be." The participant will classify his average pain in the last 7 days.
Functional capacity 8 weeks after randomization VISA-P questionnaire assesses the symptoms and disability of patients with patellar tendinopathy. It is a questionnaire with eight questions, six of them on a Likert scale, ranging from 0 to 10 points, where 0 represents the maximum severity of the disease and 10 represents no pain or limitation. Question 7 has four possible answers (0, 4, 7 and 10 points). Question 8 has a subdivision (8A, 8B and 8C), in which only one can be answered, depending on the perception of pain during sport activities, varying up to 30 points. The total score of the questionnaire varies between 0 and 100 points, with 100 points corresponding to the absence of pain or disability.
- Secondary Outcome Measures
Name Time Method Muscular strength 8 weeks after randomization The hand dynamometer will be used to measure the strength of the quadriceps femoris, hamstring, gluteus maximus, gluteus medius and lateral hip rotators.
Pain intensity during rest 12 weeks and 6 months after randomization This outcome will be evaluated by an 11-point scale ranging from 0 to 10, in which 0 represents "no pain" and 10 represents "pain as bad as it could be." The participant will classify his average pain in the last 7 days.
Triple hop test 8 weeks after randomization The patient will perform a test composed of three consecutive jumps, as far as possible, always landing on the same foot.
Pressure pain threshold 8 weeks after randomization The patient will perform 10 repetitions of the complete unipodal squat on an inclined plane and sequentially will be placed on a stretcher lying comfortably with the knee flexed at 20 degrees. The patient should indicate the point of greatest pain in the tendon, which will be marked to be the location of the tip of the algometer, and the distance to the apex of the patella will be measured to use the same point in the assessment after treatment. If the patient does not present pain in the assessment after treatment, the point standardized in the initial evaluation will be used. If the patient still presents pain, the point of greatest pain will be evaluated. For measurement, pressure will be applied until the patient experiences a mild pain sensation (pain level 1), when he will be instructed to press the algometer button to stop the test.
Pain intensity during squat 8 weeks after randomization This outcome will be evaluated by an 11-point scale ranging from 0 to 10, in which 0 represents "no pain" and 10 represents "pain as bad as it could be". The patient will classify his pain during a complete isotonic unipodal squat on an inclined plane.
Functional capacity 12 weeks and 6 months after randomization VISA-P questionnaire assesses the symptoms and disability of patients with patellar tendinopathy. It is a questionnaire with eight questions, six of them on a Likert scale, ranging from 0 to 10 points, where 0 represents the maximum severity of the disease and 10 represents no pain or limitation. Question 7 has four possible answers (0, 4, 7 and 10 points). Question 8 has a subdivision (8A, 8B and 8C), in which only one can be answered, depending on the perception of pain during sport activities, varying up to 30 points. The total score of the questionnaire varies between 0 and 100 points, with 100 points corresponding to the absence of pain or disability.
Pain intensity Eigth weeks, before and after each intervention session This outcome will be evaluated by an 11-point scale ranging from 0 to 10, in which 0 represents "no pain" and 10 represents "pain as bad as it could be". The patient will rate the pain during rest before and after each intervention session.
