Abstract
Introduction: Partial lobectomy is one of the surgeries chosen in the early stages
of some diseases such as lung cancer. After thoracic surgeries or some
respiratory diseases, both hard and soft structures undergo changes that lead
to stiffness, lack of mobility, changing the mechanics and the correct
respiratory pattern. Case presentation: A 75-year-old female patient entered
the pulmonary rehabilitation program of the “Hospital de la Baxada”
at Paraná, Entre Ríos, Argentina; referred to by a lower left lobectomy due to
lung cancer. Treatment and evolution plan: The patient attended the
pulmonary rehabilitation program, for 6 weeks she trained varying the load. We
observed a significant change in recovery, compared at the minute of completing
the first test the dyspnea was 4 and in the second test 3, the patient told us
that after the flexibility session she felt she was able to breathe normally. Conclusion:
In the case presented, the application of flexibility techniques increased
exercise capacity.

Resumen
Aumento de la capacidad de ejercicio tras una sesión de flexibilidad en paciente con lobectomía pulmonar parcial
Introducción: La lobectomía parcial es una de las operaciones elegida en estadios tempranos de la enfermedad como cáncer del pulmón. Frente
a determinadas situaciones como cirugías
torácicas o algunas patologías
respiratorias, tanto estructuras
duras como blandas sufren cambios que llevan a la rigidez, pérdida de movilidad, alterando la mecánica y el correcto
patrón respiratorio. Presentación de caso: Paciente femenina de 75 años ingresó al programa de rehabilitación
pulmonar del Hospital de la
Baxada de Paraná, Entre Ríos,
Argentina; derivada por una lobectomía inferior izquierda debido a un cáncer pulmonar. Plan de tratamiento y evolución: La paciente asistió
al programa de rehabilitación pulmonar y durante 6
semanas entrenó variando diversas características de la
carga. Observamos un cambio significativo en la recuperación,
comparando al minuto de haber finalizado el primer test la disnea era de 4 y en el segundo test
una de 3, esto fue acompañado por el relato de la paciente, comentando que luego
de la sesión de flexibilidad ella sentía estar con mayor capacidad para tomar aire. Conclusión: En el caso presentado, la aplicación de técnicas de flexibilidad aumentó la capacidad
de ejercicio.

Partial lobectomy is one of the surgeries chosen in the early stages of
some diseases, such as lung cancer, which involves removing the affected lung
lobe [1].
Facing certain situations such as thoracic surgeries or some respiratory
diseases, both hard and soft structures undergo changes that lead to stiffness,
lack of mobility, changing the mechanic and the correct respiratory pattern.
Among the changes mentioned we can find the retraction of myofascial chains
such as the inspiratory, the suspensory and the shoulder anterointernal chain,
among others.
Our accessory inspiratory muscles are thorax suspensors, are tonic and
have the tendency to retract [2]. This condition creates an increase in
expiratory time that ends up in air trap and hyperinflation.
This situation is increased during the exercise and produces a dynamic
hyperinflation with a transitory increase of the lung volumes that has
important mechanical repercussions. Therefore, dyspnea is increased, and
exercise capacity is limited [3,4].
Flexibility training is present in both Argentinian [5] and
International Pulmonary Rehabilitation Guidelines [6], but there is no
scientific evidence about the changes that the daily training of this one
causes in patients with respiratory diseases with exercise capacity. The
aim of this case report is to inform the influence of flexibility training into
exercise capacity.
A 75 years old female patient was admitted to the pulmonary
rehabilitation program of “Hospital de la Baxada” in
Paraná, Entre Ríos, Argentina; referred to by a lower left lobectomy due to a
lung cancer. The patient had Dyspnea grade 3 according to the modified Medical
Research Council Scale (mMRC). The spirometry
performed after the surgery showed the following values: Forced Expiratory
Volume (VEF1) 1.54 L (77%), Forced Vital Capacity (FVC) 1.91 L (79%), VEF/FVC
80.6. She performed a 6 Minutes Walking Test (6MWT) according to the American
Thoracic Society criteria. She walked 340 meters, with 95% as a lower oxygen
saturation value, and a dyspnea grade 4 according to the Borg Modified Scale.
The patient attended the pulmonary rehabilitation program for 6 weeks
and trained varying loads. During the next 6 weeks she got through a stagnation
period, without being able to increase intensities or improve the timing on her
training program due to her dyspnea.
The patient was observed having both shoulders up during the walking
march, sign of suspensory chain retraction, and because of that, it was decided
to change the treatment strategy applying new techniques previously the
training.
The first intervention was to perform a constant work
rated exercise test (CWRET) at 3.2 km/h (80% of maximum aerobic speed in
the incremental test). The result was a time limit (Tlim)
of 813 seconds, at the end, the patient perceived a dyspnea of 7 measured with
the modified Borg scale, SpO2 of 96% and a heart rate (HR) of 98bpm.
A minute after finishing, the patient reported dyspnea 4.
The
patient was summoned at 72 hrs for a new CWRET, but
after 20 minutes of flexibility work was performed, using the principles of
re-education of myofascial chains performing the frog posture to the floor,
emphasizing the work of the suspensory, inspiratory and shoulder anterointernal
chain. The CWRET was immediately performed at 3.2km / h and ended with a Tlim of 1270 seconds and a dyspnea of 7, a SpO2 of
97% and a HR of 94 bpm, at the minute of recovery the patient had dyspnea of 3
a SpO2 of 97% and a HR of 89bpm.
Graph 1 shows how the perception of dyspnea progresses much slower in
the second test than in the first, thus achieving a longer test time. If we
make a comparison at isotime (last minute elapsed
that both CWRET matches), the patient reported a dyspnea of 7 and in the second
test a dyspnea of 4. In Figure 1 we can see an improvement in the suspensory
chain and alignment of the inspiratory chain correction and shoulder
anterointernal chain.

Discussion
We observed a significant change in recovery (table I), compared at the
minute of having finished the first test the dyspnea was 4 and in the second
test was 3. There were no changes in the SpO2 that are
clinically relevant, since the patient did not present any type of alteration
in both tests.

effort during stress testing
The patient managed to walk 457 seconds more, exceeding the clinically
meaningful difference of 100 seconds [7], ending with the same dyspnea as in
the first test. A possible weakness of the study is not having a
continuous walk test CWRET at after a week to see the evolution of the patient.
The patient was given an instruction with home exercises to perform daily.
According to our knowledge this is the first report in which flexibility
training improves exercise capacity in a patient with partial lobectomy
measured by a CWRET. None of the tests were developed with adverse events, and
the patient did not have difficulty in treadmill, because she was trained in
the use of it. A blind evaluator was present at the study, and the patient was
unaware of the objective of the study.
Due to these findings, we should investigate whether these changes
continue with these home exercises and for how long. More studies are required
to specify the ideal flexibility work times to be applied routinely in
pulmonary rehabilitation programs. In addition, randomized clinical studies are
necessary so that what we observe here can be proven.
In the case presented, the application of flexibility techniques reduced
the subjective perception of effort for the same workload and increased
exercise capacity in a patient referred to by a left lower lobectomy due to
lung cancer.
