Brief Summary

Chronic low back pain is a common musculoskeletal condition affects the general population. Low back pain constitutes a major burden to health care system and society. Several authors have found that the deep abdominal muscles and multifidus are affected in low back pain. Dry needling has shown improve the cross-sectional area of the multifidus. Percutaneous electrical nerve stimulation has shown reduce pain in several conditions. There are not studies that had investigated the impact of percutaneous neuromuscular electrical stimulation (PNMES) in the deep muscles in patients with chronic low back pain. Hypothesis: PNMES in the multifidus muscle plus motor control exercise program in patients with chronic low back pain is better than sham PNMES plus exercise and transcutaneous electrical nerve stimulation (TENS) plus exercise

Outcome Measures

Primary Outcomes (2)

  • Increased cross-sectional area in activation

    The increase in height from the resting position to the submaximal contraction in the lumbar multifidus will be measured

    Baseline, one hour from baseline after PNMES treatment 1, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • Changes in the measurements of the multifidus and tranverse of the abdomen at rest.

    Changes in the height of the multifidus at rest

    Baseline, one hour from baseline after PNMES treatment 1, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

Secondary Outcomes (14)

  • Intensity of Pain

    (Baseline, one hour from baseline after PNMES treatment 1 (only at rest), 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • Pressure pain threshold using an algometer

    Baseline, one hour from baseline after PNMES treatment 1, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • Temporal summation

    Baseline, one hour from baseline after PNMES treatment 1, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • Conditioned pain modulation

    Baseline, one hour from baseline after PNMES treatment 1, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • Pain Grade Questionnaire

    Baseline, 6 weeks from baseline, 18 weeks from baseline and 30 weeks from baseline

  • +9 more secondary outcomes

Study Arms (4)

PNMES plus exercise

EXPERIMENTAL

6-week intervention program with 3 treatment sessions of PNMES and motor control exercise program.

Other: Percutaneous neuromuscular electrical stimulation (PNMES) plus motor control exercise program

Sham PNMES (introducing the needle) plus exercise

SHAM COMPARATOR

Sham PNMES (introducing the needle) plus motor control exercise program

Other: Sham PNMES (introducing the needle) plus motor control exercise program

TENS plus exercise

ACTIVE COMPARATOR

6-week intervention program with 3 treatment sessions of TENS plus motor control exercise program.

Other: TENS plus motor control exercise program

Placebo PNMES (without inserting the needle) plus exercise

PLACEBO COMPARATOR

6-week intervention program with 3 treatment sessions of placebo PNMES (without inserting the needle) and exercise

Other: Sham PNMES (without inserting the needle) plus motor control exercise program

Interventions

The technique consists of a muscular stimulation of the deep lumbar multifidus by means of a TENS current applied through four dry needling or acupuncture needles introduced by ultrasound guidance in said muscle 30 minutes. This will add to a protocol of motor control exercises for deep abdominal and lumbar muscles.

Also known as: Percutaneous electric nerve stimulation (PENS)
PNMES plus exercise

The same procedure will be performed as in the experimental treatment, but in this case, the electric current will be placebo and only the first 15 seconds will slightly notice it. This will add to a protocol of motor control exercises for deep abdominal and lumbar muscles.

Also known as: Sham PENS
Sham PNMES (introducing the needle) plus exercise

Transcutaneous electrical nerve stimulation will be applied through 4 patches / adhesives placed in your lower back for 30 minutes. This will add to a protocol of motor control exercises for deep abdominal and lumbar muscles.

Also known as: TENS
TENS plus exercise

The same procedure will be performed as in the experimental treatment, but in this case, the needle will not be inserted and the electric current will be placebo and only the first 15 seconds will slightly notice it. This will add to a protocol of motor control exercises for deep abdominal and lumbar muscles.

Also known as: Sham PENS
Placebo PNMES (without inserting the needle) plus exercise
