# Hypertonia of the Big Toe Revealing Parkinson’s Disease: A Case Report

## TL;DR

This case report highlights how big toe stiffness can be an early sign of Parkinson's disease, emphasizing the need for thorough neurological exams.

## Contribution

The report presents hallux hypertonia as a distinctive and under-recognized clinical feature of Parkinson’s disease.

## Key findings

- Hallux hypertonia is a significant motor symptom in Parkinson’s disease.
- Early detection through neurological evaluation can improve diagnostic accuracy.
- The case underscores the importance of considering atypical motor signs in PD diagnosis.

## Abstract

Despite being less commonly discussed than other motor symptoms such as tremors and bradykinesia, hypertonia of the hallux holds diagnostic and prognostic significance in Parkinson’s disease (PD). This motor anomaly is dissected within the context of the broader clinical spectrum of PD symptoms, emphasizing its importance alongside its cardinal symptoms. This case report underscores the importance of accurate clinical assessment especially thorough neurological evaluation in discerning hallux hypertonia, potentially enabling early disease recognition and intervention. By synthesizing these clinical insights, we trust that this case report contributes to an enhanced understanding of hypertonia of the hallux as a distinctive clinical presentation in PD fostering improved diagnostic precision.
