Brief Summary

this study will be conducted to investigate the effect of trunk extensors induced fatigue on balance and lumber position sense in adolescents

Conditions

Healthy; Adolescent

Keywords

induced trunk extensor fatigue; balance; Lumbar Position Sense

Outcome Measures

Primary Outcomes (2)

• balance

  Assessment of balance will be done using the biodex balance system

  up to thirty minutes

• joint position error

  Inclinometer will be used to assess lumbar joint position error

  up to thirty minutes

Study Arms (1)

Biering-sorenson protocol

EXPERIMENTAL

Biering-Sorensen protocol will be used to induce back muscle fatigue, and a marked decrease in the maximum force in trunk extension

Other: Biering-sorenson protocol

Interventions

Biering-sorenson protocol OTHER

* Students shouldn't perform any vigorous activity a day before assessment. * Frist, therapist will request from each participant to watch videos to understand how the test should be applied. * The starting position will be a half prone lying on a plinth with the superior edge of the iliac crest horizontal at the edge of the plinth and the arms crossed over the chest. * The participant should keep the unsupported upper part of the body. * The lower limbs will strategically be stabilized with straps. * The participant will be asked to maintain the upper body in a horizontal position and the timer started. * The test ends if the participant can maintain the previous position for 4 minutes (240 seconds) or can no longer maintain the set position before 4 minutes elapses. The stop time is recorded. * There is considerable range of mean fatigue times reported for the Biering-Sørensen test in the literature ranging from 84s to 180s in healthy males.
