Introduction

In recent years, neoplastic diseases – and lung cancer in particular – have been the cause of around 1.1 million deaths worldwide [1, 2] and in the developed countries they have been the cause of death even two times more often [3]. Also, women die of lung neoplastic diseases three times less often than men [4].

The pathological changes occurring in the lungs lead to disorders of airflow in pulmonary alveoli with different levels of intensity [5, 6]. The consequences of such abnormalities involve a very high strain for the whole respiratory system, including respiratory muscles [7, 8]. The disorders of ventilation and gas exchange cause respiratory acidosis and are directly responsible for the decrease of the physical capability of the body.

Lung functioning disorders impact the cardiovascular system, causing the pressure level in the pulmonary artery system to rise, which consequently puts much strain on the right ventricle of the heart [9]. Blood coagulability of oncological patients is also impaired, which is an indirect cause of increase of resistance in blood vessels and of growth of pulmonary tension level [10]. Ventilation-circulatory disorders contribute substantially to the advancement of symptoms of physical effort intolerance [11].

The skeletal muscles appear to show an impaired ability of oxygen metabolism, which is manifested in lactic acidosis despite the proper functioning of lung ventilation [12].

The rehabilitation for oncological patients aims to prevent the continuous decrease in physical capability and at the same time is designed to increase the quality of immunity of the organism in the struggle with lung cancer. The conducted study aimed to determine how much physiotherapy can improve the overall fitness of the patients.

Material and methods

The study involved 70 men in the age of 63.58 ±8.09, all diagnosed with lung cancer according to WHO criteria from 1997. The patients underwent rehabilitation treatment in the Regional Specialist Hospital for Tuberculosis and Lung Diseases in Ludwikowo and a series of radiation therapy sessions in Greater Poland Cancer Centre. The observed patients did not differ much in terms of their age, height, body mass, BMI, the levels of doses of their therapeutic radiation and in terms of the length of stay in the hospital.

The groups included in the study are described in Table I, II and III.

The patients underwent the Fullerton test immediately before the commencement of rehabilitation treatment and immediately after the finish of the treatment. On the basis of the results achieved in the 6-minute walk test of the preliminary examination (a constituent of the Fullerton test), the patients were divided into three observation groups:

• group P1 – patients who covered the distance of more than 400 m,

• group P2 – patients who covered the distance of more than 300 m but less than 400 m,

• group P3 – patients who covered the distance of more than 200 m, but less than 300 m.

In addition to the systemic therapeutic exercise program, the patients from group P1 also had ergometric bicycle training included in their therapy. The exercise sessions took place in a gymnasium, in groups of 8-10 persons, in the late morning hours, and were delivered by skilled rehabilitators in the form of 30-minute meetings, 5 times a week. Moreover, the patients underwent ergometric bicycle training under rehabilitators’ supervision 3 times a week – also in the late morning hours. The training involved 15-minute cycling with the level of intensity at 50 to 70% of maximum heart rate (HR max), which was preceded by a 3-minute warm-up; the last 2 minutes of the cycling did not include any load. Additionally, there were also regular everyday walks around the hospital park.

Group P2 pursued systemic therapeutic exercises and breathing exercises according to the plan in the late mor­ning hours. The afternoon hours involved walks around the hospital park.

Group P3 had its rehabilitation based only on walking around the hospital park. All of the patients had the same types of test and examinations, including marking of the same parameters.

The Fullerton test (Fullerton Functional Fitness Test), designed to assess physical capability and fitness, comprises 6 trials, which allow one to make an indirect evaluation of the following parameters: strength of the upper and lower body, motor coordination, balance and aerobic endurance. The order of trials in the test is strictly specified. It begins with an attempt to flex the forearm (arm curl), then follows the “back scratch”, rising from a chair, the “chair sit and reach”, the “8 feet” trial, and the 6-minute walk trial comes last. In some cases, the last trial is replaced with the 2-minute “step-in-place” – depending on participants’ motor abilities [13, 14].

The abovementioned tests were approved by the District Board of Scientific Research Ethics. Also, the participants of the test gave their written consent after being introduced to the methods and ways of conducting the study.

The statistical hypotheses were validated by means of non-parametric tests. The differences between the groups were verified by Mann-Whitney U test, while the differences between the levels of parameters of each individuals – with measurements taken both before and after the effort – were verified by the Wilcoxon test. The results of the tests were considered as valid with the level of statistical significance of p < 0.05.

Results

In the first group, P1 (Table IV), which had ergonomic bicycle training apart from physiotherapy, the following results were noted: forearm flexion level increased from 15.02 to 15.95 times, with the improvement rate of 6.18%; “back scratch” – the distance improved from 12.33 cm to 9.54 cm, so the improvement rate was 22.68%; rising from a chair – an improvement from 11.02 to 11.12 times, with the improvement rate of 0.86%, which seems to be a rather slight change; however, the “chair sit and reach” improved from 1.60 cm to 0.19 cm, which constitutes an increase of fitness by 88.06%; the “8 feet” trial involved a change from 7.21 s to 7.14 s, which – at the rate of 1.02% – is also rather insignificant. The distance covered in the 6-minute walk test got shorter, from 445.24 m to 429.76 m (3.48%), which indicates deterioration of capability of the patients from group P1 – even despite the increase of fitness and agility.

Patients from group P2 (Table V) underwent physio­therapy only, with the following results: forearm flexion level increased from 10.89 to 14.44 times (32.65%); “back scratch” – the result became worse, falling from 16.89 cm to 17.11 cm (1.32%); rising from a chair improved from 9.00 to 10.22 times (13.58%); the “chair sit and reach” got worse, changing from 8.19 cm to 11.22 cm (36.95%); there was an improvement in the “8 feet” trial, from 9.56 s to 8.75 s (8.46%). Similarly, the distance covered in the 6-minute walk test also got better, increasing from 311.39 m to 362.22 m, with the increase rate of 16.32%, proving that the patients are in better shape than before the rehabilitation.

Group P3 (Table VI) had no rehabilitation exercises and the following results were noted: forearm flexion level increased from 12.00 to 13.20 times (10.00%); “back scratch” – a deterioration, with the distance growing bigger from 14.70 cm to 15.50 cm (5.44%); the score in rising from a chair

rose from 8.00 to 8.80 times (10.00%); the “chair sit and reach”, in turn, got worse, with a fall from 14.75 cm to 13.00 cm (11.68%); the “8 feet” trial results got a bit worse, falling from 10.25 s to 9.97 s (2.70%); the distance covered in the 6-minute walk test rose from 219.00 m to 235.00 m (7.31%), which points to the improvement of physical capability during the rehabilitation.

Discussion

Application of different methods of rehabilitation with treated groups usually leads to an improvement in functional parameters, which directly improves the quality of life [15]. Researchers point to a significant increase of overall physical activity and to a decreased fatigability after 6-week interval training using treadmill exercises with an intensity of 80% of HR max. Durak et al. [16] write about a considerable increase of muscular strength and endurance – along with a noticeable improvement of the quality of life – in a study group subject to 10 weeks of supervised aerobic and weight training, while Schwartz et al. [17] described exercises of low and moderate intensity, pursued for 8 weeks by a group of patients with chemotherapy in progress, and noted a decrease in the quality of life, an increase of fatigability and of body mass – but with a slight increase of functional efficiency. Courneya et al. [18] wrote about post-chemotherapy patients who underwent a rehabilitation program involving walking and riding a cycloergometer bicycle. They came to the conclusion that there was a relationship between the intensity of the experienced fatigue and the duration of training. Similar observations were also made by Dimeo et al. [19] by monitoring and assessing the capability and the development of fatigue among patients under chemotherapy. Pinto et al. [20], in turn, did not find any difference between the training and the untreated group in terms of fatigue and capability. Still, the training group displayed a higher level of overall vitality.

In our own presented research, there was a more or less visible improvement of most condition-assessment para­meters in all of the groups participating in rehabilitation. Yet, only those groups without additional endurance training were found to display an improvement of endurance in the 6-minute walk test. Members of group P1 – which under­went the most intensive rehabilitation – appeared to be able to shorten the distance covered in the 6-minute walk test after the rehabilitation treatment. The Fullerton test makes it possible to determine physical abilities such as the strength of lower and upper limbs, flexibility, variabi­lity or coordination, and many authors have used this test, pointing to an increase of the patients’ muscle strength after application of different rehabilitation programs. Hayes et al. [21] looked into the issue of muscle strength in two groups of patients. They noted that in the group which pursued training there was a substantial improvement of muscle strength of the upper and lower parts of the body, as well as of motor coordination. In a similar way, Mello et al. [22] compared the results of their untreated and treated groups and observed an increase of muscle strength among the members of the treated group. Segal et al. [23] arrived at corresponding conclusions, pointing to a bigger increase of physical functional capabilities of the patients from the treated group compared to those from the untreated one. Dimeo et al. [15] also found an increase of the maximum functional abilities, as well as a decrease of the intensity of pain, among the members of the group pursuing treadmill training – unlike among those in the non-training group.

This study also showed that after application of rehabilitation treatment there followed positive functional changes involving an increase of muscle strength of upper limbs in group P1 by 6.18% (p = 0.01) and an increase of upper limb flexibility in the same group by 22.68% (p = 0.01). However, there were no changes in the strength of lower limbs in this group – with a simultaneous decrease of the length of the covered distance by 3.48%. As for group P2, in turn, the strength of upper limbs increased by 32.65% (p = 0.00), the strength of lower limbs by 13.58% (p = 0.01), the flexibility of upper limbs grew by 1.32% and of lower limbs by 36.95%, and the covered distance went up by 16.32% (p = 0.01). The parameter of strength of both upper and lower limbs, as well as the covered distance in group P3, improved, too. What is more, Burnham and Wilcox [24] also reported an increase of flexibility of the lower part of the body after introduction of therapeutic training.

Conclusions

The results obtained in the study lead to the following conclusions:

1. Intensive training for patients with lung cancer led to adverse changes of capability and physical fitness of the members of the study group.

2. A moderate rehabilitation program based on systemic therapeutic training – without endurance training – improved the fitness and capability of the patients after the rehabilitation treatment finished.

3. Physical therapy without any endurance training may be recommended as a dedicated method of rehabilitation for this group of patients.
