Effect of the Cognitive Strategy During Trunk Muscle Endurance in Patients With Lumbar Hernia Surgery

Muscle endurance will be evaluated on two exercises: Biering-Sorensen Test and Prone Plank Test. Each test will be assessed in different days following a randomized order.

About this study

All patients will be encouraged to achieve the maximum time to task failure, stopped only by muscular fatigue or pain precluding to maintain the position. Each exercise will perform under two conditions.

On the control condition, the patients will perform both tests without any cognitive condition, while on the experimental condition they will be instructed to perform both tests while performing a mathematical subtracting task (starting at 300, by sevens).

The starting condition will be randomly assigned with a 5-minute rest prior to the next condition. Time to task failure and pain perception using a visual analog scale will be assessed.

Treatment and study plan

Biering-Sorensen Test and Prone Plank Test

Diagnostic Test

All patients will be encouraged to achieve the maximum time to task failure, stopped only by muscular fatigue or pain precluding to maintain the position.

Primary outcomes

  1. Time to task failure

    Time frame: through study completion, an average of 2 week

    Time in seconds from 0 to failure, where higher values represent a best muscle endurance.

  2. Pain evaluation

    Time frame: through study completion, an average of 2 week

    Pain will be measured by the Visual Analog Scale for pain (VAS) from 0 to 10, where higher values represent a worse outcome.

Secondary outcomes

  1. Pain Interference: Kinesiophobia

    Time frame: through study completion, an average of 2 week

    Kinesiophobia will be evaluated by Tampa Scale for Kinesiophobia (TSK-11SV) (Spanish adaptation. Gómez-Pérez, López-Martínez y Ruiz-Párraga, 2011). Scoring: Items are summed, with a total score from 11-44 and higher values represent a worse outcome (more pain interference in behavior).
