Balance, Gait and Foot Pressure Distribution in Neuropathic Pain Associated with Lumbar Disc Degeneration.

Background

This study aimed to evaluate the effects of NP associated with LDD on balance, gait and foot pressure distribution.

Methods

This prospective controlled study was conducted on 42 individuals aged between 40-70 years. There were 3 groups in the study: individuals diagnosed with NP associated with LDD (n=14), individuals with LDD without NP(n=14), and the control group (n=14). The Force Plate system and Core Balance System measured static and dynamic postural balance and stability limits. Gait and dynamic plantar pressure distribution analyses were performed with a computerized gait evaluation system.

Results

The Leeds Assessment of Neuropathic Signs and Symptoms (LANSS), VAS during gait, and Oswestry Disability Index (ODI)scores were higher in LDD with NP group than in LDD without NP group (p<0. 05). It was found that LDD with NP group had backward dynamic balance control (p<0. 05). There was no significant difference in balance control, dynamic plantar pressure distribution, and spatiotemporal gait parameters between the groups (p>0. 05).

Conclusion

Although participants with NP had higher levels of pain severity in gait and disability, there was no difference in postural balance, dynamic plantar pressure distribution, and spatiotemporal gait parameters compared to participants with LDD without NP and healthy individuals. All participants with LDD were unilaterally affected. Therefore, postural balance and gait tasks would be able to compensate for the unaffected limb.
