These alterations lead to falls especially as the disease progresses. Based on the observation that postural control improved in patients with vestibular dysfunction after audio-biofeedback training we tested the feasibility and effects of this training modality in patients with PD. Methods Seven patients with PD were included in a pilot study comprised of a six weeks intervention program. The training was individualized to each patient s needs and was delivered using an audio-biofeedback ABF system with headphones. The training was focused on improving posture sit-to-stand abilities and dynamic balance in various positions. Non-parametric statistics were used to evaluate training effects. Results The ABF system was well accepted by all participants with no adverse events reported. Patients declared high satisfaction with the training. A significant improvement of balance as assessed by the Berg Balance Scale was observed improvement of 3 p 0.032 and a trend in the Timed up and go test improvement of 11 p 0.07 was also seen. In addition the training appeared to have a positive influence on psychosocial aspects of the disease as assessed by the Parkinson s disease quality of life questionnaire PDQ-39 and the level of depression as assessed by the Geriatric Depression Scale. Conclusions This is to our knowledge the first report demonstrating that audio-biofeedback training for patients with PD
