简要总结
This clinical trial compares the effects of Strain Counterstrain technique versus Graston Technique on pain and range of motion in patients with patellofemoral pain syndrome.
Adults with patellofemoral pain syndrome were included in this study. A total of 60 participants were divided into two groups with 30 patients in each group.
One group received Strain Counterstrain technique and the other group received Graston Technique. Pain was assessed using the Kujala Scoring System and functional status was measured using a substructural questionnaire. Range of motion was also evaluated before and after treatment.
The main goal of this study is to determine which technique is more effective in reducing pain and improving knee function in patients with patellofemoral pain syndrome.
详细描述
Patellofemoral Pain Syndrome (PFPS) is a common musculoskeletal condition characterized by anterior knee pain, especially during activities like squatting, climbing stairs, or prolonged sitting. Conservative management through manual therapy is widely used, but comparative effectiveness of different techniques remains unclear.
This randomized clinical trial was designed to compare the effects of Strain Counterstrain (SCS) technique versus Graston Technique on pain intensity, knee range of motion, and functional status in patients diagnosed with patellofemoral pain syndrome.
A total of 60 participants diagnosed with PFPS were recruited and randomly allocated into two equal groups, with 30 patients in each group. Group A received Strain Counterstrain technique, which involves passive positioning of the affected tissue to achieve a position of comfort and reduce tender point sensitivity. Group B received Graston Technique, an instrument-assisted soft tissue mobilization (IASTM) therapy that uses specialized stainless steel instruments to detect and treat soft tissue restrictions, scar tissue, and fascial adhesions around the knee.
The intervention period lasted for 12 weeks with 3 sessions per week. Outcome measures were assessed at baseline and post-intervention. Pain was evaluated using the Kujala Anterior Knee Pain Scale, also known as the Kujala Scoring System, which is a validated tool for PFPS. Functional status was assessed using a substructural questionnaire evaluating daily activities. Knee range of motion was measured using a standard goniometer.
The primary objective of this study is to determine whether Strain Counterstrain or Graston Technique provides superior outcomes in terms of pain reduction, improved range of motion, and enhanced functional capacity in patients with patellofemoral pain syndrome. The findings will help clinicians select the most effective manual therapy approach for managing PFPS.
