Comparison of peak shoulder and elbow mechanical loads during weight-relief lifts and sitting pivot transfers among manual wheelchair users with spinal cord injury

Figure. Overview of laboratory assessment of (a) sitting pivot transfers and (b) weight-relief lifts.

This study compared shoulder and elbow mechanical loads when the dominant upper limb (UL) played three distinct roles among a group of 13 individuals with paraplegia: leading UL when transferring from one seat to another of even height; trailing UL when transferring from one seat to another of even height; and lifting UL during weight-relief lifts when hands were placed in a similar position. The results confirmed that when transferring, individuals require more effort than when performing weight-relief lifts, particularly at the shoulder. The development of optimal shoulder strength is suggested before transfer training is initiated. Transfer aids may be useful to reduce UL mechanical load during transfers.
