简要总结
The purpose of this study is to evaluate the efficacy of a knee isometric program (KIP) as compared to the current gold standard treatment for anterior knee pain (Patellofemoral Clinical Practice Guideline [CPG] - Academy of Orthopedic Physical Therapy).
详细描述
Participants will be randomly allocated into the KIP or control intervention via spreadsheet randomization algorithm at the time of consenting. Each patient will have equivalent experiences for the duration of the study regardless of allocation. Time spent with the physical therapist, daily length of exercise program, outcome measures recorded, and home education materials will all be similar for each group. Participants will be asked to refrain from any outside forms of lower extremity strengthening or training. Usage of pain medication (including over-the-counter and prescription drugs) will be documented in the pain journal. Proper use of the pain journal will be explained during consent and again at the initial intake session.

研究组 & 干预措施
Knee Isometric Program (KIP) - Intervention
This group will incorporate the KIP protocol, which is a modified physical therapy regimen that is less time-intensive than the gold standard counterpart. Typical structured/skilled physical therapy occurs over the course of 4-8 weeks with 1-2 visits per week to establish improved lower extremity muscle strength, education, and improve gross function. Home exercise programs (HEP) are utilized in tandem with physical therapy visits so that patients are completing interventions 4-5 days per week. Long-term maintenance is generally provided via a refined comprehensive HEP on completion and discharge from formal physical therapy.
干预措施: Knee Isometric Program (KIP) (Behavioral)
Patellofemoral Clinical Practice Guideline (CPG) - Control
This group will incorporate the standard of care physical therapy regimen which includes a specific and structured combination of quadriceps and gluteal strengthening as defined in the patellofemoral pain clinical practice guideline. Typical structured/skilled physical therapy occurs over the course of 4-8 weeks with 1-2 visits per week to establish improved lower extremity muscle strength, education, and improve gross function. Home exercise programs (HEP) are utilized in tandem with physical therapy visits so that patients are completing interventions 4-5 days per week. Long-term maintenance is generally provided via a refined comprehensive HEP on completion and discharge from formal physical therapy.
结局指标
主要结局
Knee Function
时间窗: Baseline, 12 weeks
Participants will complete the lower extremity functional scale (LEFS) at session 1 and at session 5 (one month follow up visit after completing physical therapy) in order to determine any change in knee function across those time periods. The LEFS is a 20 question survey that asks about a person's ability to perform everyday tasks and each question is scored on a scale from 0 to 4 with 0 being extreme difficulty or unable to perform activity and 4 being no difficulty. These responses are then summed to get a total score out of 80 maximum points, and the lower the score, the greater the disability.
Functional Stability
时间窗: Baseline, 12 weeks
Functional stability will be assessed at sessions 1 and 5 to determine each participant's dynamic balance, and it will be used to assess anterior reach specifically. This test has the participant stand on one leg while reaching out in 3 different directions with the other lower extremity, and thus measures strength, stability, and balance in multiple directions. The composite score is calculated by summing the three reach directions. Higher scores reflect better outcomes.
Objective Muscular Strength Performance
时间窗: Baseline, 12 weeks
Participants will have their quad strength measured using a handheld dynamometer (HHD) at session 1 and session 5 of their study visits in order to determine with that data how muscular strength changes following each physical therapy regimen.
Subjective Pain
时间窗: Baseline, 2 weeks, 4 weeks, 6 weeks, 12 weeks
Participants will complete the Numerical Pain Rating Scale (NPRS) in a pain and medication journal in order to subjectively rate their pain over over 4-5 days between each session, except for after session 4 in which they will document twice a day for 20 days. The NPRS rates pain on a scale of 0 to 10 with 0 being no pain and 10 being the worst pain imaginable, and subjects will reflect pain pre and post physical therapy. Additionally, they will be asked to reflect any pain medication that they take on a given day.
