The purpose of this study will be to compare the effects of instrument assisted soft tissue mobilization at different muscle lengths on pain pressure thresholds and measures of flexibility.
Instrument assisted soft tissue mobilization is a widely used manual therapy technique, which aims at reducing pain and improving range of motion. Evidence regarding acute responses to instrument assisted soft tissue mobilization at different muscle lengths is lacking. Therefore, the purpose of our study was to conduct a cross-over trial and compare the acute effects of instrument assisted soft tissue mobilization at short and long muscle lengths of the calf muscles on pain pressure thresholds and measures of flexibility.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Treated segment - stretched | Experimental | Instrument assisted soft tissue mobilization will be completed with the calf muscles in a shortened position (30° knee flexion and full ankle plantar flexion). |

| Treated segment - shortened | Experimental | Instrument assisted soft tissue mobilization will be completed with the calf muscles in a lengthened position (full knee extension and approximately 0° ankle dorsiflexion). |

| Instrument assisted soft tissue mobilization | Other | We will perform instrument assisted soft tissue mobilization on calf muscles. The intervention will last 9 min. For the first minute of treatment light pressure will be applied for tissue preparation. Afterwards, four different strokes will be applied by maintaining the tool at a 30° of inclination for one minute. This will be repeated for a second set, with a tool inclination of 45°. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain pressure threshold | Pain pressure threshold will be measured via handheld algometer on the proximal third of the distance between medial condyle of the femur and lateral malleolus. | 30 minutes |
| Passive dorsiflexion range of motion | Passive dorsiflexion will be measured via two wooden boards connected with a hinge. We will apply a standardized torque of 30,9 Nm via handheld dynamometer. Each visit, participants will be measured before and after the performed intervention. | 30 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Stand and reach test | With the help of a standardized measuring tool, participants will activelly bend as low as possible. | 30 minutes |
| Lumbar spine flexibility | Sagittal profile of the spine will be measured measured via device: Idiag M360 (MediMouse, Idiag AG, Fehraltorf, Switzerland). End range of motion of the whole lumbar spine was recorded. |
