Brief summary
The aim of this study is to determine and compare the effects of static and PNF hamstring stretching exercises on joint pain, hamstring flexibility and functional status in patients with knee osteoarthritis.
Detailed description
A total of 36 patients between the ages of 40 and 75 who were diagnosed with Kellgren-Lawrence Stage II and III knee OA by the physician were included in the study. Participants were divided into two groups as static stretching group or PNF stretching group. Patients' demographic and clinical information was recorded. Pain intensity was evaluated with visual pain scale, hamstring flexibility with Active Knee Extension Test, functional status with Western Ontario and McMasters University Osteoarthritis Index and Timed Get Up and Go Test. In addition to the standard physiotherapy program, the subjects practiced stretching exercises according to the groups that they've been separated. Evaluations were repeated in the end of the treatment and in the follow-up.
Interventions
OTHERStatic Stretching
Static hamstring stretching exercise lasting 30 seconds and 10 repetitions under the supervision of the physiotherapist
OTHERPNF Stretching
PNF hold-relax stretching technique that consists of 10 seconds isometric contraction, 30 seconds hamstring stretching and 10 repetitions under the supervision of the physiotherapist

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Active Knee Extension Test for Hamstring Flexibility | Baseline and post-intervention | Higher values represent better outcomes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analogue Scale for Pain | Baseline and post-intervention | The scale varies from 0 to 10. Higher values represent worse outcomes. |
| Western Ontario and McMaster Universities Osteoarthritis Index | Baseline and post-intervention | The scale varies from 0 to 96. Higher values represent worse outcomes. |
| The Timed Up & Go Test | Baseline and post-intervention | Higher values represent worse outcomes. |
