Pulse Assessment Sites01:11

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Summary

Percutaneous Achilles tendon repair may lead to impaired ankle proprioception, particularly at plantar flexion. Further research is needed to develop interventions for improving ankle joint position sense after surgery.

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Biomechanics

Background:

  • Achilles tendon injuries are common, often requiring surgical repair.
  • Percutaneous repair techniques aim for minimally invasive treatment.
  • Assessing functional recovery, especially proprioception, is crucial for patient outcomes.

Purpose of the Study:

  • To evaluate ankle function and proprioception after endoscopic percutaneous Achilles tendon repair.
  • To test the hypothesis that patients exhibit impaired ankle proprioception on the operated side.

Main Methods:

  • Nineteen male patients underwent percutaneous Achilles tendon repair.
  • Evaluated bilateral ankle active angle reproduction, isokinetic torque, hop distance, and jump height.
  • Compared patient outcomes to age- and sex-matched healthy controls.

Main Results:

  • No significant differences were found in peak torque, hop distance, jump height, or ankle position sense at 10° dorsiflexion between operated and unoperated sides.
  • A significant deficit in ankle joint position sense at 15° plantar flexion was observed in patients compared to controls.
  • Patients showed poorer joint position sense at both 10° dorsiflexion and 15° plantar flexion on the affected side compared to controls.

Conclusions:

  • Patients exhibit impaired ankle proprioception at 15° plantar flexion at least one year post-percutaneous Achilles tendon repair.
  • The unaffected limb's proprioception remained comparable to controls.
  • Further longitudinal studies are required to investigate therapeutic strategies for enhancing proprioception.
