Résumé
Objectives: Psychomotor retardation is part of Major Depression (MD) diagnosis criteria and has been assimilated to bradykinesia, even though there is a clear lack of objective measurement of motor activity in MD. We conducted a study to evaluate bradykinesia, posture and gait parameters in MD patients with an ambulatory system, allowing continuous motor measurements.
Methods: Patients with DSM-IV MD and healthy controls matched for age and sex were asked to carry on with their usual activities while being recorded for 6 hours by a wireless autonomous ambulatory system, containing miniature gyroscopes, data-logger, battery and flash memory. allowing continuous recording of upper limbs movements (speed, amplitude and activity (% of time with movement)), posture (% of time standing, walking, lying or sitting) and gait parameters (speed, cadence, stance, double support, stride).
Results: Hands activity was significantly lower in depressed patients, as compared to controls (MD: 40%, controls: 60%; p<0.05). Speed of hand movements (p= 0.13) and their amplitude (p=0.71) were similar to controls. MD patients had a trend to spend more time lying or sitting than controls (p=0.06) but did not differ in terms of any gait parameters.
Conclusion: Patients with MD displayed less hand movements than controls and tended to spend more time lying or sitting over 6 hours, but did not differ in terms of speed and amplitude of movement, nor in gait parameters. These results suggest that psychomotor retardation classically described in MD might be the expression of a paucity of movement rather than a bradykinesia as observed in parkinsonism and might involved different (nondopaminergic) mechanisms.
