Inclusion criteria
Inclusion criteria: General study inclusion criteria: ? 18 years of age and older ? Individuals where their current predominant sport / physical activity is cycling (indoor, road or MTB) ? Cyclists with at least 12 months experience of regular cycling ? Cycling at least an average of 30km/week over the past 12 months. ? No current pain (in any anatomical area other than the knee) during cycling, that is severe enough to interfere with the cyclist’s ability to cycle, or stop them from training or competing (=5/10 on VAS) Specific inclusion criteria for the PFP group: ? Pain around the anterior aspect of the knee, insidious onset and no evidence of trauma ? Minimum of four weeks history of anterior knee pain (pain, 3/> of 10) ? Present with at least one of the following: o Pain around or behind the patella, which is aggravated by at least one activity that loads the patellofemoral joint during weight bearing on a flexed knee (e.g. squatting, stair ambulation, jogging / running, hopping / jumping, cycling). o Crepitus or grinding sensation emanating from the patellofemoral joint during knee flexion movements o Tenderness on patellar facet palpation o Small effusion ? Pain on sitting, rising on sitting, or straightening the knee following sitting Pain present on at least 1 clinical test (vastus medialis coordination test, patellar apprehension test, eccentric step test, Waldron’s test (Phases I and II), Clarke’s test, standard step-down test, lateral step down test, single-leg squat)
Exclusion criteria
Exclusion criteria: ? Current pain (=5/10 on VAS), in any anatomical area other than the knee, during cycling that is severe enough to interfere with the cyclists ability to, and even stop them from, training or competing. ? Clinical, radiographic, or MRI findings indicative of other specific knee pathology other than PFP in the last 12 month: including meniscal, ligament, or cartilage injury, as well as osteoarthritis (stage 3 and 4), epiphysitis, significant knee joint effusion, or recurrent patellar subluxation or dislocation in the last 12 months. ? Previous surgery to the knee joint within the past 3 months. ? Previous acute trauma to the knee joint with an effect on the presenting clinical condition within the previous 3 months
