Study summary

  • see if there is significant difference between subjects with forward head rounded shoulder posture and subjects with normal posture in hand grip strength in asymptomatic young adults
  • see if there is significant difference between subjects with rounded shoulder posture and subjects with normal posture in hand grip strength in asymptomatic young adults
Read the detailed description
  • in forward head posture there is flexion in lower cervical vertebrae that causes tension on lower cervical nerve roots according to Harrison systemic review and these lower cervical nerve roots supply hand muscles
  • also in rounded shoulder posture there is weakness in scapular stabilizers and retractors which affect proximal stability of the arm
  • proximal stability is important for distal mobility
  • so from this biomechanical point of veiw we conduct this study to see if forward head and rounded shoulder posture can affect hand grip strength in asymptomatic young adults.
