The Relationship between Independent Transfer Skills and Upper Limb Kinetics in Wheelchair Users

This study investigates how well wheelchair users perform transfers and how that affects the forces on their arms. Researchers looked at the connection between transfer skills, as measured by a special tool, and the loads on the upper body. The study found that using the right transfer techniques can lower the stress on the shoulders and elbows. However, some techniques might increase the load on the leading arm. Understanding these effects can help wheelchair users protect their upper limbs. By understanding the kinetic outcomes associated with each skill, wheelchair users can achieve the best load-relieving effects for their upper extremities, ultimately preventing injuries and preserving upper limb function for long-term use.

• 1
  Proper transfer skills are linked to the magnitude and timing of joint moments in the upper limbs, with specific skills targeting the trailing arm associated with lower moments at the shoulder and elbow.
• 2
  Certain transfer skills involving the leading arm can increase the magnitude or rate of loading on that side, indicating a potential trade-off in load distribution depending on the technique used.
• 3
  Wheelchair users with better overall transfer skills, as indicated by higher TAI part 1 scores, tend to experience lower moments on the trailing elbow and a lower rate of rise of resultant moment on the leading elbow, but increased extension shoulder moment on the leading side.
