Generally, a patient’s exercise program
(for active physical therapy) should encompass a combination of the
following:
Stretching
Most patients who have suffered from low back pain should
stretch their hamstring muscles (in the back of the
thigh) once or twice daily. Patients who have low back pain tend
to have tight hamstrings, and patients with tight
hamstrings tend to have low back pain. It is not known which comes
first, but it is clear that hamstring tightness
limits motion in the pelvis and can place it in a position that
increases stress across the low back. Therefore, it
follows that stretching the hamstring muscles typically helps decrease
the intensity of a patient’s back pain and
the frequency of recurrences.
Simple hamstring stretching does not
take much time, although it can be difficult to remember, especially
if there is little or no pain. Therefore, hamstring stretching
is best done at the same time every day so it becomes part of
a person’s daily routine. A hamstring stretching routine
should include applying pressure to lengthen the hamstring
muscle for 30-45 seconds at a time twice daily. The pressure on
the muscle should be applied evenly and
bouncing should be avoided, since a bouncing motion will trigger
a spasm response in the muscle being stretched.
Strengthening/pain
relief exercises
There are two primary forms of exercise for strengthening
and/or pain relief that tend to be used for specific
conditions: McKenzie exercises and dynamic lumbar stabilization
exercises. When appropriate, these two forms
of physical therapy may be combined.
McKenzie exercises are
named after a physical therapist in New Zealand who noted that
extending the spine could reduce pain generated from the disc space.
With the McKenzie approach, physical therapy to extend the
spine can help “centralize” the patient’s pain
by moving it away from the extremities (leg or arm) to the back.
Back pain is usually better tolerated than leg pain or arm pain,
and the theory of the approach is that centralizing
the pain allows the source of the pain to be treated rather than
the symptoms.
For the dynamic lumbar stabilization exercises, the
physical therapist first tries to find the patient’s “neutral”
spine, or the position that allows the patient to feel most comfortable.
The back muscles are then exercised to
teach the spine how to stay in this position. This technique relies
on proprioception, or the awareness of where
one’s joints are positioned. Performed on an ongoing basis,
these exercises can help keep the back strong and
well positioned.
Low-impact aerobic conditioning
Reconditioning through low-impact
aerobic exercise is very useful for both rehabilitation and maintenance
of the lower back. The following types of aerobic exercise are gentle
on the back and, when done on a regular basis,
highly effective in providing conditioning:
-
Walking. In
general, walking is very gentle on the back, and walking
two to three miles three times per week is very helpful for patients.
-
Stationary bicycling. If walking is painful, stationary
bicycling is also effective.
-
Water therapy. Exercise in the water provides effective
conditioning while minimizing stress on the back.
Even patients with a very busy
schedule should be able to maintain a moderate exercise regimen
that encompasses stretching, strengthening, and aerobic conditioning. |
