Clinically Informed Framework for Forearm, Wrist, and Grip Strengthening
Presented by: Nicholas Maroldi, DPT, OCS, CHT
Wrist and grip strengthening is among the most under-systematized domains in hand therapy, often defaulting to putty progressions and generic home exercise programs. This session establishes a biomechanically grounded framework for loading the wrist across the rehabilitation continuum: from acute ligamentous and TFCC injuries through return to sport and occupational demand. Using the intercalated segment model as a conceptual foundation, attendees will examine the mechanical rationale for neutral wrist loading, staged isometric stabilization, and functional grip progression, with specific application to SLIL reconstruction, TFCC repair, DRUJ instability, and post-distal radius fracture rehabilitation.
Learning Objectives
Upon completion of this session, attendees will be able to:
- Explain the biomechanical significance of the intercalated segment and articulate why the absence of direct muscular attachments to the proximal carpal row requires a fundamentally different approach to strengthening than is applied at any other major joint.
- Identify the mechanical risk factors and injury patterns associated with commonly prescribed forearm and grip strengthening exercises — including wrist curls, hammer rotations, and repetitive grip loading — and apply this knowledge to patient screening and exercise modification.
- Apply a staged isometric wrist stabilization progression across the rehabilitation continuum, from early post-operative protected loading through advanced dynamic stabilization, with specific application to SLIL reconstruction, TFCC repair, DRUJ instability, and post-distal radius fracture rehabilitation.
- Design evidence-informed forearm, wrist, and grip strengthening programs utilizing neutral wrist mechanics, functional grip patterns with extended time under tension, and load parameters appropriate to tissue healing stage and patient demand level.
- Differentiate strengthening program design across high-risk clinical populations — including patients with positive ulnar variance, ligamentous laxity, active carpal instability, and post-operative wrist pathology — and justify exercise selection, modification, and progression criteria for each.
