Summary

This summary is machine-generated.

Stroke patients have more difficulty turning toward their paretic side, linked to trunk control. Improving trunk flexibility, strength, and control is key for rehabilitation to reduce falls.

Background:

Turning difficulties are common in stroke survivors, yet the relationship between turning direction and trunk control remains unclear.
Trunk flexibility and strength are vital for trunk control, but their impact on turning performance is not well-understood.

Purpose of the Study:

To investigate turning direction differences in stroke patients concerning turn duration and angular velocity.
To examine the association between turning performance and trunk function in chronic stroke survivors.

Main Methods:

A cross-sectional study involving 28 chronic stroke patients.
Wearable sensors assessed 360° turning in place for turn duration and angular velocity.
Trunk flexibility, strength, and control were measured using standard clinical tools.

Main Results:

Stroke patients exhibited significantly longer turn durations and lower angular velocity when turning towards the paretic side compared to the nonparetic side.
Turning performance towards the paretic side correlated with trunk flexion, rotation, flexor strength, dynamic sitting balance, and coordination.
No significant relationship was found between trunk function and turning performance towards the nonparetic side.

Conclusions:

Stroke patients face greater turning challenges when turning towards their paretic side.
Impaired trunk flexibility, strength, and control are linked to turning dysfunction in stroke survivors, potentially increasing fall risk.
Clinical interventions should focus on enhancing trunk function to improve turning ability and reduce falls in stroke rehabilitation.
