Brief Summary
The purpose of this study is to determine differences in lower extremity landing biomechanics and real-world physical activity between individuals with patellar tendinopathy compared to individuals wi...
Eligibility Criteria
Inclusion
- The investigators will recruit a convenience sample of participants who meet the following overall criteria:
- Age 15 and post-pubertal (confirmed by Pubertal Development Scale Questionnaire) - 28 years
- Actively participating within an organized sport setting (high school, collegiate, club, competitive intramural sports) in their respective team's weekly training and competitions, quantified by a Tegner Activity Level Scale of at least 5.
Exclusion
- The following exclusion criteria will be applied to all participants:
- Any anterior knee pain with no patellar tendon abnormality on ultrasound assessment.
- History of any knee joint surgery ever.
- History of other (non-knee) lower extremity surgery in the last 1 year.
- History of lower extremity injury in last 6 months (other than patellar tendinopathy).
- An injection (corticosteroids, plasma-rich-protein, etc.) to the patellar tendon in the last 3 months.
- Known history of osteoarthritis or current symptoms related to osteoarthritis (i.e. stiffness, swelling).
- Participation in formal rehabilitation for patellar tendinopathy in prior 3 months
- Known neurological disorders, including: stroke, multiple sclerosis, ALS, diabetic neuropathy, epilepsy, traumatic brain injury resulting in loss of consciousness, concussion within the last 6 months, cranial neural surgery, balance disorders.
- Use of pacemaker or another implantable electronic device.
- History of cardiac arrhythmia or any cardiac condition.
- History of psychiatric disorder. \*
- History of cancer in the brain or thigh musculature.
- Pubertal Development Scale Score \< 12 (Stages 1-4)
- Note: Rationale for exclusion of individuals with a history of psychiatric disorders is that these individuals may have taken or be taking pharmacological agents that could affect pain or neuromuscular control.
