Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Introduction: the management of Patellofemoral Pain (PFP) is focused on therapeutic exercise (TE) to improve muscle strength and motor control. Recent studies suggest that the addition of radiofrequency diathermy (RFD) obtain greater short-term improvements in knee pain than TE alone. As there is no follow up data, the aim of this research is to assess the long-term effects of adding RFD to TE on pain, function and quality of life on PFP patients.

Methods: a single-blind randomized controlled trial will be conducted. Participants diagnosed of PFP will be allocated in either a TE group or a RFD+TE one. Sociodemographic data, knee pain, and lower limb function will be collected. Each group will performed 20 min of daily knee and hip supervised TE along three weeks with the addition of ten sessions of RFD for the RFD+TE group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental

Application of radiofrequency diathermy in addition to the exercises protocol same Exercise protocol than control group. Ten sessions of treatment were applied: daily the first week (Monday to Friday), three the second week (Monday, Wednesday, Friday) and two the last week (Monday and Thursday)

Group Type EXPERIMENTAL

Diathermy by emission of Radiofrequency

Intervention Type DEVICE

Applied only to experimental group

Therapeutic exercise

Intervention Type OTHER

Applied to both arms/groups

Control

Exercise protocol consisting of: eccentric and concentric strengthening of quadriceps (three squat series of 20 repetitions), hamstrings (three series of 20 seconds performing the bridge exercise), gluteus medius (three series of 20 seconds performing the clam exercise), gastrocnemius and soleus (three series of stretching exercises for 1 minute each). These exercises will be performed along 20 minutes approximately with a minute of rest between each exercise series, never exceeding 3mm in VAS. Participants have to assist to a local facility center to be supervised at doing the exercises daily (from Monday two Friday) along three weeks.
