3. The Subtlety of Grip Weakness: An Underestimated Marker of HIBM
Grip weakness presents another cornerstone symptom of HIBM. This symptom typically manifests as an increasing difficulty in grasping or holding onto objects. It may start innocuously with challenges in opening jars or gripping pens and progress to struggles with holding heavier objects or performing fine motor tasks.
The impact of grip weakness extends beyond physical difficulties; it often serves as an emotional reminder of the ongoing changes in the body, potentially leading to feelings of frustration and helplessness. Recognizing grip weakness as a symptom of HIBM can pave the way for early interventions, providing support and strategies to help maintain hand function and independence in daily tasks.
Grip weakness in HIBM arises from the involvement of the distal muscles, specifically those in the hands. This focus on distal muscle groups aligns with the overall pattern of muscle involvement in HIBM, providing another piece in the diagnostic puzzle. (3)
