The Analysis of the Impact of 5-minute Massage Session on the Muscle Stiffness and Tone
Study Details
Study Description
Brief Summary
The study design was a randomised, controlled, parallel, two-arm trial. The subjects were randomly assigned to one of the study groups: the intervention group or the control group. The passive mechanical properties, i.e. the stiffness and tone of the medial and lateral gastrocnemius muscle (dominant leg) were assessed. Measures were taken twice: in the intervention group before and after the 5-minute massage session, and in the control group at the beginning of the meeting and again after 5 minutes.

Detailed Description
The purpose of this study was to determine whether a 5-minute massage, applied to healthy individuals, may change the passive mechanical muscle properties, which supposedly may prevent MSDs. We decided to carry out our experiment on the medial and lateral gastrocnemius muscle because of its accessibility and crucial role in locomotion. MyotonPRO and TMG S2 devices were used to assess the stiffness and radial muscle displacement of the gastrocnemius muscle respectively.

Outcome Measures
Primary Outcome Measures
- Changes in maximal displacement of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
The maximal radial displacement is produced in the muscle belly after the electrical stimulation. Measuring device: TMG S2
- Changes in delay time of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Delay time is the time in which the muscle displacement increases to 10% after the electrical stimulation. Measuring device: TMG S2
- Changes in contraction time of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Contraction time is the time between 10% and 90% of the muscle displacement after the electrical stimulation. Measuring device: TMG S2
- Changes in sustain time of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Sustain time is the time between 50% of maximum contraction to 50% of maximum relaxation of a muscle after the electrical stimulation. Measuring device: TMG S2
- Changes in relaxation time of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Relaxation time is the time between 90% of maximum contraction and 50% of maximum relaxation of a muscle after the electrical stimulation. Measuring device: TMG S2
- Changes in oscillation frequency of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
The oscillation frequency characterizes the tension of muscle tissue. Measuring device: MyotonPRO
- Changes in dynamic stiffness of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
The dynamic stiffness corresponds to the soft tissues' capacity to resist external forces. Measuring device: MyotonPRO
- Changes in logarithmic decrement of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Logarithmic decrement is the dissipation of the tissue oscillation. Measuring device: MyotonPRO
- Changes in mechanical stress relaxation time of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Mechanical stress relaxation time is the time needed for the muscle to recover to its initial shape. Measuring device: MyotonPRO
- Changes in creep of the medial and lateral gastrocnemius muscle [1) baseline, 2) immediately after the massage session]
Creep is the ratio of relaxation (R) and time between the beginning of the mechanical impulse and the time point of maximal displacement Measuring device: MyotonPRO
