Spinal cord stimulation therapy for gait dysfunction in progressive supranuclear palsy patients.
Article in Journal of neurology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere are no effective symptomatic treatments for progressive supranuclear palsy (PSP). Recent studies report benefits of spinal cord stimulation (SCS) for freezing of gait (FOG) and gait disorders in Parkinson's disease and atypical Parkinsonism patients. This is the first study to report therapeutic effects of SCS in Richardson's syndrome PSP (PSP-RS) patients.
methodsEpidural SCS was implanted in three female PSP-RS participants (3.2 ± 1.3 years with disease). Six programs (300-400 µs/30-130 Hz) were randomly tested at suprathreshold intensity on separate days. The setting that best improved gait/FOG was used daily by each participant in the study. Protokinetics walkway captured spatiotemporal gait measures and FOG episodes (turning on the spot and while walking) and clinical scales including FOG questionnaire, UPDRS-III (OFF-/ON-L-dopa), and participant-perceived global impression of change (GISC) were collected at pre-SCS, and 3, 6, 12 months post-SCS.
resultsParticipant #1 demonstrated the highest GISC score (6.5/10) with a consistent reduction of FOGs by 43.8%, UPDRS-III score (- 5 points), and improved step length and stride velocity (33.6%) while maintaining a L-dopa response of ~ 12% over the 12 months. Participant #2, walking FOG frequency and turning duration was reduced by 39.0% (OFF-L-dopa), and ON-L-dopa UPDRS-III score worsened (+ 5 points) at 12 months. Participant #3, FOG frequency reduced by 75% up to 6 months rating a GISC 3/10 score, however disease severity worsened at 12 months. Ambulatory gait parameters universally improved by 29.6% in all participants.
conclusionThe results support the benefit of SCS for FOG and gait symptoms in PSP-RS and suggests early SCS intervention for dopaminergic-resistant gait should be considered.
