Conditions

Patellofemoral Pain Syndrome

Brief summary

The purpose of this study is to determine if a lower back treatment would change the knee pain intensity and the level of functional activities as well as the muscle activities in people with anterior knee pain. The investigators hypothesized that the lower back treatment may change the hip and knee muscle activities as well as reduce the knee pain intensity and improve the functional activities in people with anterior knee pain.

Interventions

OTHERLumbopelvic Manipulation

High-velocity low-amplitude non-specific lumbopelvic thrust manipulation

OTHERPassive lumbar spine flexion and extension

Passive lumbar spine flexion and extension without reaching the physiological end feel for 1 min from a side lying position.
