Abstract
Objective
This study aimed to assess reachable workspace (RWS) in patients post-osteosynthesis of shoulder, elbow, or wrist fractures and explore correlations with self-reported function and kinesiophobia.
Design
An observational case-control study compared patients with fractures to a control group, utilizing questionnaires and 3D kinematic data.
Participants
The sample included 66 individuals who had undergone osteosynthesis: 21 with shoulder fractures, 10 with elbow fractures, and 22 with wrist fractures. A control group of 23 participants without upper limb pathologies was also established. Inclusion criteria were ages 18–80 and recent surgery; exclusions were previous upper limb surgeries, cervical pathologies, systemic diseases or nerve injuries.
Main outcome measure
RWS, the three-dimensional volume the hand can reach, was measured with participants standing. Kinesiophobia was assessed using the Tampa Scale of Kinesiophobia (TKS), and physical disability and pain were measured using the DASH questionnaire and the Numeric Pain Rating Scale (NPRS).
Results
Fracture groups exhibited significant RWS reductions (62–85%) compared to the control group, with no significant differences among the fracture types. RWS showed a high correlation with TKS (R = 0.77) and a moderate correlation with DASH (R = 0.52).
Conclusion
RWS is a promising biomechanical parameter for assessing upper limb function post-fracture, aiding in refining rehabilitation protocols.
