About
Subjects between 14 and 40 years of age referred to physical therapy with a diagnosis of PFPS will be randomly assigned to one of two groups. The first group (PFPS) will be treated pragmatically. The second group (PFPS+DN) will receive the same pragmatic approach with the addition of dry needling intervention. The dry needling intervention will be delivered based on the treating physical therapist's examination of the patient's soft tissue mobility deficits, muscle activation deficits, or referred pain patterns.
Full description
All interventions delivered to both study groups will be provided by licensed physical therapists at Duke Sports Medicine. The frequency of visits and duration of physical therapy care will be determined on an individual basis. Both groups will be expected to perform an individualized home exercise program to supplement formal therapy visits. The PFPS group will receive a pragmatic treatment approach reflective of currently accepted interventions. The clinician will have the ability to select appropriate interventions based on the presentation/need of each patient. These interventions may include: stretching (iliotibial band, hip flexor, lateral retinaculum); patellar taping; kinesiology taping; bracing; joint mobilization (patella, ankle, hip); orthotics/footwear recommendations; pain modalities such as Ice, electric stimulation, laser; soft tissue mobilization (manual or instrument assisted) for restricted tissues such as peri-patellar tissues, iliotibial band, tensor fasciae latae, hamstrings, calf, quadriceps, hip flexors, and gluteals. The PFPS+DN group will be treated in the same manner described above with the addition of the dry needling intervention. The dry needling intervention will be prescriptive in that each provider will assess patient for the presence of a trigger point that may be contributing either directly or indirectly to the patient's symptoms and perform the intervention per the following guidelines. First, the presence of a trigger point must be verified by locating a palpable taught band, a hypersensitive tender area, referred pain of the MTrP in response to compression, a Jump Sign - response from patient who winces, may cry out, or withdraw, or a local twitch response provoked by manually snapping the taut band. Second, a muscle may be selected for dry needling if that muscle is assumed to be contributing to tissue extensibility restriction, motor control dysfunction, or hyperactivity.
