Psychopathology and the rehabilitation of patients with chronic low back pain disability.
Recent research has clearly demonstrated the important role that psychopathology and other psychosocial factors can play in chronic low back pain disability (CLBPD). The purpose of this study was to evaluate whether diagnosed psychopathology is a significant limiting factor in the successful rehabilitation of patients with CLBPD. One hundred fifty-two CLBPD patients (97 men, 55 women) were given a structured psychiatric interview for official DSM-III-R diagnosis of psychopathology upon entering an intensive 3-week functional restoration treatment program. ⋯ They were subsequently tracked for 1 year after program completion, with treatment outcome being defined as return-to-work status at this 1-year time period. Results demonstrated that, though more than 90% of patients obtained at least one Axis I diagnosis, and more than 50% obtained at least one Axis II diagnosis, neither type nor degree of psychopathology were significantly predictive of a patient's ability to successfully return to work. These prospective study results suggest that if a treatment program is structured to appropriately manage psychopathology, as is the case of an intensive functional restoration program, then psychopathology does not have to interfere with successful treatment outcome.

Variant and invariant characteristics of the sit-to-stand task in healthy elderly adults.
The purpose of this study was to identify kinetic, kinematic, and electromyographic (EMG) characteristics during sit-to-stand (STS) in healthy elderly subjects that were affected by changes in movement speed or initial starting position. Eight healthy elderly adults performed the STS movement at natural and fast speeds. Their ankles were placed in either 5 degrees or 18 degrees of dorsiflexion prior to the movement. ⋯ However, when expressed as a percent of total movement time, normalized extensor muscle onsets were found to be earlier during fast movement of the task, whereas the other variables were not different. Changing the initial ankle position affected muscle onsets, duration of movement phases, and joint excursion. We conclude from these data that many of the characteristics of the sit-to-stand movement are speed invariant and therefore the STS movement is for the most part programmed.(ABSTRACT TRUNCATED AT 250 WORDS)
