Inclusion criteria comprised of the clinical diagnosis of progressive supranuclear palsy, a levodopa-resistant gait and balance disorder, age <75 years, and absence of dementia or major psychiatric co-morbidities. Effects of stimulation frequencies at 8, 20, 60 and 130 Hz on motor scores and gait were assessed. Motor scores were followed up for two years postoperatively. Activities of daily living, frequency of falls, health-related quality of life, cognition and mood at 12 months were compared to baseline parameters. Surgical and stimulation related adverse events were assessed.Bilateral pedunculopontine nucleus deep brain stimulation at 8 Hz significantly improved axial motor symptoms and cyclic gait parameters, while high frequency stimulation did not ameliorate gait and balance but improved hypokinesia. This improvement however did not translate into clinically relevant benefits. Frequency of falls was not reduced. Activities of daily living, quality of life and frontal cognitive functions declined, while mood remained unchanged.Bilateral pedunculopontine nucleus deep brain stimulation in progressive supranuclear palsy generates frequency-dependent effects with improvement of cyclic gait parameters at low frequency and amelioration of hypokinesia at high frequency stimulation. However, these effects do not translate into a clinically important improvement.}, keywords = {Accidental Falls: prevention $\&$ control / Activities of Daily Living / Aged / Cognitive Dysfunction: etiology / Cognitive Dysfunction: therapy / Deep Brain Stimulation: methods / Female / Gait Disorders, Neurologic: etiology / Gait Disorders, Neurologic: therapy / Humans / Hypokinesia: etiology / Hypokinesia: therapy / Male / Outcome Assessment, Health Care / Pedunculopontine Tegmental Nucleus / Postural Balance / Quality of Life / Supranuclear Palsy, Progressive: complications / Supranuclear Palsy, Progressive: therapy / Deep brain stimulation (Other) / Gait (Other) / Parkinsonian disorders (Other) / Pedunculopontine nucleus (Other) / Progressive supranuclear palsy (Other) / Quality of life (Other)}, cin = {Core Technical Staff / U Clinical Researchers - Magdeburg}, ddc = {610}, cid = {I:(DE-2719)1340007 / I:(DE-2719)7000000}, pnm = {344 - Clinical and Health Care Research (POF3-344)}, pid = {G:(DE-HGF)POF3-344}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:29503154}, doi = {10.1016/j.parkreldis.2018.02.027}, url = {https://pub.dzne.de/record/139970}, }
