Patellofemoral pain syndrome (PFPS) can significantly affect an individual's ability perform to functional activities, such as walking, running, climbing stairs, and sitting for prolonged periods. PFPS is often associated with pain and discomfort in the front of the knee, which can limit an individual's range of motion and cause difficulty with weight-bearing activities. The pain may also be exacerbated by activities that involve bending the knee, such as squatting or kneeling. Whole body vibration (WBV) has been suggested as a potential intervention for patellofemoral pain syndrome (PFPS). Some studies have shown that WBV can improve muscle strength, balance, and proprioception, which are all factors that may contribute to PFPS. Additionally, WBV may help reduce pain and improve functional abilities in individuals with PFPS However, the evidence for the effectiveness of WBV as an intervention for PFPS is still limited, and more research is needed to fully understand its potential benefits and limitations. It is important to note that WBV may not be suitable for all individuals with PFPS.

HYPOTHESES: There will be no significant difference on dorsi/planter flexor ratio , functional activities and pain level after adding the whole body vibration to traditional treatment of PFPS RESEARCH QUESTION: What is the impact of whole-body vibration on dorsi/planter flexor ratio, functional activities and pain levels in individuals with PFPS?

patients will receive WBV training in addition to traditional training will be performed on a tri-planar (mostly vertical, Z axis) oscillating vibration platform (Power PlateR pro5™; Power Plate North America, Inc., Northbrook, IL,USA) for 20-30 minutes per session. WBV training will be supervised and performed in a clinic three days a week with at least one day between each session for four weeks (total of 12 sessions).
10 minutes warm-up (lower extremity stretching exercises), 20-30 minutes period of strength exercises with three sets of 10-15 repetitions (isometric quadriceps setting, knee extensions, double-legged wall squat), and 5 minutes cool-down (lower extremity stretching exercises). Lower extremity stretching exercises consisted of quadriceps, hamstring, gastrocnemius and iliotibial band stretching with 3 repetitions for 30 s each muscle.

RECRUITINGDorsi/planter torque ratio
dorsi/planter torque ratio will be measured through the Biodex System 4-Pro Isokinetic Strength Dynamometer for assessment of muscle torque
Time frame: one month
functional activities
Kujala Anterior Knee Pain Scale, which includes questions related to functional activities.
Time frame: one month
Pain intensity
10 cm Visual Analogue Scale (VAS) was used to assess pain intensity during activity in patients with patellofemoral pain (PFP). The scale ranged from 0, indicating "no pain," to 100, representing the "worst pain imaginable.
