Physical exercise improves functional capacity and quality of life in patients with acromegaly: a 12-week follow-up study.

OBJECTIVE

Although the focus of acromegaly treatment is the hormonal control of the disease, a new perspective must be given to the functional rehabilitation of these patients, especially when considering the recent increase in survival. The aim of this study was to evaluate the effects of therapist-oriented home rehabilitation (TOHR) on patients with acromegaly.

PATIENTS AND METHODS

Seventeen adults with acromegaly followed an exercise programme from a booklet with instructions for each exercise prescribed, for 2 months, and were reassessed after 1 month of washout. At each of the 3 timepoints (before and after the intervention and at the 1-month follow-up), the participants were subjected to the following assessments: body composition through bioimpedance, health-related quality of life (HRQoL) using the Acromegaly Quality of Life (AcroQoL) questionnaire, general fatigue through the Functional Assessment of Chronic Illness Therapy-Fatigue scale, handgrip strength, lower extremity functionality using isometric dynamometry and the Lower Extremity Functional Scale (LEFS), body balance through stabilometry, and functional capacity through 6-minute walking distance (6MWD).

RESULTS

After performing TOHR, improvements in general fatigue, quadriceps muscle strength, LEFS, 6MWD, balance control and all AcroQoL dimensions were observed (all P < 0.05). After 1 month of washout, however, these gains were lost for all parameters, except the LEFS and balance control.

CONCLUSIONS

In acromegaly, TOHR results in improvements in muscle function, functional capacity, general fatigue, body balance, and HRQoL. Large randomized controlled trials are needed to replicate these benefits and to recommend rehabilitation, especially for those with long-term illness.
