Brief summary
This pilot study aims to i) represents the feasibility of the study design and ii) to point out acute effects of thoracic spine mobilization on skin-blood flow, erythema and the sympathetic nervous system.
Interventions
PROCEDUREMobilization posterior
Participant in sitting position. Central thoracic mobilization from anteriors-to-posterior.
PROCEDUREMobilization anterior
Participant in prone position. Central thoracic mobilization from posterior-to-anterior.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility: Adherence of recruited participants | Every 4 weeks up to 2 years | Defined as the number of drop-outs and presence of participants which invited. Measurement unit: number |
| Feasibility of the investigating procedure | Every 4 weeks up to 2 years | Measured the burden of testing procedure. Measurement units = number and percentage |
| Feasibility of the mobilization intervention from posterior-to-anterior on thoracic vertebrae | Every 4 weeks up to 2 years | Measured adverse effects as pain and harm results to participants. Measurement units = number and percentage |
| Feasibility of the mobilization intervention from anterior-to-posterior on thoracic vertebrae | Every 4 weeks up to 2 years | Measured as adverse effects as pain and harm results to participants. Measurement units = number and percentage. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of skin-blood flow variation | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | Laser doppler imaging is used for measuring microcirculatory changes. Measurement units: perfusion unit |
| Rate of heart rate variability (HRV) | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | HRV is measured as the variations of the time interval between two consecutive cardiac beats registered by means Polar watch RS800 is used to measures (HRV). Measurement unit: High frequency-band (HF-Band) and Low frequency-band (LF-Band) |
| Rate of erythema | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | Tristimulus surface colorimetry is used for measuring erythema. Measurement units: Erythema index |
| Rate of systolic blood pressure value (mmHg) | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | Omron MIT Elite Plus is used for measuring systolic blood flow. iMeasurement units: mmHg (millimeter of mercury) |
| Rate of diastolic blood pressure value (mmHg) changes | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | Omron MIT Elite Plus is used for measuring diastolic blood pressureMeasurement units: mmHg (millimeter of mercury) |
| Rate of heartbeat frequency | Change from baseline imediately after, 2, 4, 6, 8 and 10 minutes after the intervention | Polar watch RS800 is used for measuring heartbeat frequency. Measurement units: beat per minute (bpm) |
