# The Effect Of A Neurodynamic Treatment On Nerve Conduction In Clients With Low Back Pain

**NCT ID:** [NCT01402895](https://clinicaltrials.gov/study/NCT01402895)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 9
- **Lead Sponsor:** McMaster University
- **Conditions:** Low Back Pain
- **Start Date:** 2011-05
- **Completion Date:** 2011-10
- **CT.gov Last Update:** 2012-02-08

## Brief Summary

The purpose of this study is to determine if a certain treatment for low back pain can change the way nerves in the leg send messages. Specifically, the investigators will examine whether a particular type of physical therapy treatment for individuals with low back pain (neurodynamic techniques) changes the speed that nerves send/receive signals to/from the leg, as compared to a different physical therapy treatment.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Males and females aged 18 years and older
* Participants who can speak English and read, understand, and fill out the consent form and questionnaires
* Participants will have a certain level of low back pain graded numerically, with or without radiation to the leg
* Clinical decision (by same individual) as safe to participate in study based on subjective history and objective examination.

Exclusion Criteria:

* An inability to tolerate sitting for 10 minutes
* Nerve conduction disorders diagnosed by a physician such as, diabetes or MS
* Current participant in an investigational drug study (within past 3 months)
```

## Arms

- **Mobilizations** (ACTIVE_COMPARATOR) — The physiotherapist will perform mobilizations to the L-spine and SI joints with the participant in a specific position.
- **Exercise** (ACTIVE_COMPARATOR) — The physiotherapist will teach the participant how to tighten the transversus abdominus muscle. The participant will be asked to do a series of these exercises.

## Interventions

- **Exercise** (OTHER) — Transversus abdominus exercise
- **Mobilizations** (OTHER) — The physiotherapist will perform mobilizations to the L-spine and SI joints with the participant in a specific position.

## Primary Outcomes

- **Change in nerve conduction studies** _(time frame: Change from baseline after intervention, on average 1.5 hours after baseline measure)_ — Motor conduction of the tibial nerve; Sensory conduction of the sural nerve; H-reflex, H:M ratio (soleus muscle)

## Secondary Outcomes

- **Change of knee extension in sitting slump test** _(time frame: Change from baseline after intervention, on average 1.5 hours after baseline measure)_
- **Change in score of Visual Analog Scale for pain** _(time frame: Change from baseline after intervention, on average 1.5 hours after baseline measure)_
