Impact of Mechanical Cervical Traction on Upper Limb Spasticity and Function Post-Stroke: A Case Series

The study aimed to address these gaps by examining the effects of mechanical cervical traction at two different forces (18.5 kgf and 2.2 kgf) on upper extremity spasticity and functional ability in stroke survivors. By utilizing validated outcome measures such as the Modified Ashworth Scale (MAS), Fugl-Meyer Assessment for Upper Extremity (FMA-UE), and the Motor Activity Log (MAL)

This study used a case series design to investigate the effects of mechanical cervical traction on upper extremity spasticity and motor function in stroke survivors. Six participants with post-stroke upper extremity spasticity were recruited and underwent cervical traction sessions under two different force conditions over four weeks. The study assessed spasticity, motor function, and daily functional activity using the Modified Ashworth Scale, FMA-UE, and Motor Activity Log. Data analysis included descriptive statistics and a qualitative analysis due to the small sample size.

This study demonstrates that mechanical cervical traction, particularly at a higher force of 18.5 kgf, can significantly reduce spasticity and enhance motor function in the upper extremities of stroke survivors. The findings indicate that higher traction forces not only decrease muscle tone more effectively but also contribute to meaningful improvements in the quality and amount of functional use of the affected limb in daily activities. The results suggest that mechanical cervical traction could be a valuable addition to the existing repertoire of rehabilitation strategies for stroke survivors, offering a non-invasive, targeted approach to managing spasticity and facilitating motor recovery. However, the variability in response observed at the lower traction force underscores the need for careful consideration of individual patient characteristics when determining the appropriate intervention parameters.

While this study provides promising evidence for the use of mechanical cervical traction in stroke rehabilitation, the limitations related to sample size and study design necessitate further research. Future studies should aim to confirm these findings in larger, more diverse populations and explore the long-term effects and optimal application protocols of cervical traction.

Mechanical cervical traction presents a promising therapeutic option that could significantly enhance the rehabilitation outcomes for stroke survivors, particularly those struggling with upper limb spasticity. Its integration into standard rehabilitation practices could improve patient independence, quality of life, and overall recovery.
