PHYSICAL THERAPY IN THE
TREATMENT OF LOW BACK PAIN
There is significant evidence in the literature to support the
utilization of physical therapy for the treatment and management
of the patient with low back pain, regardless of the duration of
the pain. The following summary relies in part on an evidence-based
review of the literature by Mark Bishop PT, PhD, CSCS.
The treatment protocols followed by The Jackson Clinics parallel
the management guidelines as described in the current medical literature.
There is ample evidence that physical therapy can be an effective
intervention if the intervention is proactive and delivered by licensed
physical therapists and assistants following evidence based treatment
guidelines. The management guidelines are as follows:
I. Acute Nonspecific Low Back Pain: Less than 7 Weeks.
1) Education:
Accurate education should be the primary focus of treatment
1,2 including expectations of a favorable prognosis, safe and effective
methods of symptom control, safe and reasonable activity modifications,
and prevention. 1,3 The physical therapist, after patient examination,
is best suited for this form of education.
2) Safe and effective symptom control
For non specific complaints, manipulation should be considered
for pain relief. 3
Modalities should not be used as primary interventions.1,4
3) Prevention
Remaining active and continuing a minimum of 30 minutes
of aerobic conditioning on 3 to 5 days a week is recommended.1
There is growing evidence that strengthening the trunk muscles,
particularly the erector spinae, is important and simple exercises
should be advocated5
4) Activation and exercise. Beside educating the patient and managing
symptoms, the therapist must ensure that the patient does not begin
the physiological cascade known as deconditioning syndrome. 6 The
deleterious effects of inactivity on bodily systems have been well
documented, and the ameliorative effects of exercise should be equally
well known. 7 The AHCPR guidelines 1 recommend the following:
Low stress aerobic exercise can prevent debilitation caused
by inactivity during the first month of symptoms, and thereafter
may help to return patients to the highest level of functioning
appropriate to their circumstances.
Conditioning exercises for the trunk (especially the back
extensors) that are gradually increased are helpful for patients
with acute low back problems, especially if symptoms persist.
Exercise quotas that are gradually increased result in better
outcomes than symptom-limited exercises.
It should be realized that there is a paradigm shift from
focusing solely on symptomatic relief to the prevention of activity
intolerance.
II. Subacute Low Back Pain: 7 weeks to 3 Months: Due to the decreased
likelihood of return to work after six months of back pain it is
imperative to treat this group of patients with aggressive intervention8
1) Education
Education continues to be of paramount importance9
The goal of treatment should be to improve activity tolerance,
and the patient should be educated that activity or exercise, not
rest, leads to comfortable performance.10
2) Activity recommendations
A graded return to sitting and lifting is recommended regardless
of symptoms. 1
A proactive disability prevention plan that emphasizes early
return to work needs to be followed. 11
3) Activation and exercise
Lindstrom et al 12 used a simple graded activation protocol
for nonspecific LBP and reported positive results concerning return
to work (5weeks earlier return to work), sick leave (8 weeks fewer
sickness absences during first and second follow-up year), back
mobility, and fitness during the follow-up period. This rehabilitation
program with operant conditioning may decrease the percentage of
persons disabled by benign LBP.
The Philadelphia Panel evidence-based guidelines recommend
that flexion, extension, and general strengthening exercises are
of clinical benefit to the patient after four weeks. 13
III. Chronic Low Back Pain: Longer than three months
1) Education: The education process again is extremely important
and should include the following:
Nature of the problem
Natural history of LBP including regression toward a mean
Importance of self-management
Non-addictive, safe and effective methods of symptom control
used in a time-contingent manner.
Importance of weight reduction, smoking cessation, and graded
exercise.
2) Safe and effective symptom control
At least nine randomized trials have evaluated the efficacy
of manipulation in the treatment of chronic LBP. The two studies
with the highest methodological quality show benefits.14,15
2) Activation and exercise
There is strong evidence that exercise therapy is effective
for chronic LBP.3,4,13
The multifidus has been shown to suffer from reflex inhibition
after an episode of LBP.16
Strengthening of multifidus has been shown to reduce recurrence
of LBP from 85% to 32% one to three years following injury.17
Strengthening of the erector spinae as demonstrated by Manniche
et al 18,19 was extremely effective in rehabilitation of patients
with low back pain.
However, telling patients who are in pain to exercise is
an ineffective strategy.20 Supervised exercise therapy programs
have been shown to be beneficial for LBP and appear to improve compliance.21,22,20
