Respironics Actiwatch L Actigraphy System, Diagnoses Sleep Disorders
Actiwatch Actigraphy System Actiwatch Family of Ambulatory Actigraphy Devices: The Actiwatch Score, Actiwatch-2, and Actiwatch Spectrum use actigraphy principles to provide sleep schedule variability, sleep quantity and quality statistics and daytime activity patterns so you can better identify therapeutic options and understand responses to treatment for patients. All three models collect reliable, objective data on sleep/wake patterns for multiple days in a subject’s ambulatory environment with the comfort and aesthetics of a standard wrist watch. Activity level is recognized as a valuable indicator for medical problems and can provide answers to many research questions. Activity levels correlate with sleep/wake patterns, pain level, mood, energy expenditure, fatigue/alertness and other quantifiable parameters. An Actiwatch actigraph also provides an objective record for tracking and documenting normal and abnormal sleep/wake patterns and PLMS. Two examples of the use of the Actiwatch are: Sleep/Wake Patterns and General Activity Level. A digitally integrated recording of wrist activity is a reliable indicator of Sleep/Wake state. The Actiwatch is an actigraphy device that is the size of a standard wrist watch. It allows for the recording of the smallest movements for days, weeks, or even months. When worn on the wrist, an Actiwatch actigraph can generate an Activity record like the one shown below to be used as a tool to document: Sleep/Wake Patterns Sleep Disorders Circadian Rhythms Disorders Disturbances brought on by Shift WorkReal time impedance display. Basic Activity Levels. Compliance with Exercise Routines. Periodic Limb Movement in Sleep (PLMS). Actiware-PLM software is used for assessing the magnitude and periodicity of limb movements during sleep. Two Actiwatch 64s are used to monitor the subject for three consecutive nights. You can assess movement in both legs on any given night to determine: Total time of PLM Total number of PLM Occurrences per leg Average PLM duration Simultaneous PLMs in both legs Sleep Disturbance from PLM AW-L Actigraph with Integrated Light Sensor The Actiwatch-L actigraph has a small, very high performance light sensor integrated into its case in place of an event marker. With each activity record that is recorded, the light level is also recorded in Lux. Like all of our Actiwatches, the AW-L uses actigraphy principles to record activity information and can be used to analyze sleep quality. The AW-L may be used to verify time, length and frequency of treatments for SAD patients (Seasonal Affective Disorder). These values may be correlated with changes in sleep/wake patterns from the actigraphy record. Specifications: Weight (without protective case): 16 grams.
