Summary
This summary is machine-generated.

Better tenodesis pinch and grasp in individuals with cervical spinal cord injury (SCI) correlate with improved daily living function. These measurements can assess hand movement changes after treatment.

Area of Science:

  • Orthopedics
  • Neurosurgery
  • Rehabilitation Medicine

Background:

  • Cervical spinal cord injury (SCI) significantly impacts upper-extremity function.
  • Stiffness and spasticity can alter tenodesis function, affecting daily activities.

Purpose of the Study:

  • To examine the variability of tenodesis function before reconstructive surgery in individuals with cervical SCI.
  • To correlate tenodesis pinch and grasp measurements with activities of daily living (ADL) performance.

Main Methods:

  • Tenodesis pinch (thumb-to-index finger contact) and grasp (finger-to-palm distance) were measured with the wrist in maximal extension.
  • Activities of daily living were assessed using the Spinal Cord Independence Measure (SCIM).

Main Results:

  • Individuals with tenodesis pinch to the proximal or middle phalanx had significantly higher SCIM scores than those with absent pinch.
  • Shorter grasp distance (improved finger closing) correlated with better SCIM mobility and total scores.
  • No association was found between the International Classification for Surgery of the Hand in Tetraplegia (ICSHT) group and SCIM scores or tenodesis measures.

Conclusions:

  • Quantifying tenodesis pinch and grasp is a simple method to characterize hand function in cervical SCI.
  • Improved tenodesis pinch and grasp are associated with better ADL performance.
  • These measurements can guide treatment and assess outcomes in tetraplegia.
