Predetermined time standards: their application in workshop settings.

There is a need for a simple, quickly applied tool which can correlate performance of the handicapped individual with that of the able-bodied worker and be easily utilized by nontechnical personnel. Efforts at both the Cerebral Palsy Center and the Rehabilitation Center in Atlanta demonstrated that the third generation of Methods-Time-Measurement (MTM-3) satisfies these criteria. As every motion involved in an operation is detailed and a corresponding time value applied, the over-all result reflects a normal rate of accomplishment more accurately than the usual methods and is especially useful in bidding jobs for the workshop. MTM-3 also has a place in the evaluation section to verify or correct existing standards on bench-type work samples and to develop more meaningful time distribution charts relating to a specific population at a center. In studies of disabled individuals, MTM-3 yields a more accurate determination of the actual degree of disability than the American Medical Association's existing estimated percentages in regard to motor skills.

Chronic pain states: their relationship to impairment and disability.

Chronic pain patients (101) were assigned ratings of impairment and disability and were assessed for organic pathology and pain behavior through comprehensive testing procedures. As predicted, higher ratings of impairment and disability were significantly associated with higher levels of both physical pathology and pain behaviors. These results indicate that conditioning and pathologic processes significantly influence impairment and disability ratings. Many patients showed higher disability than impairment ratings, which suggests the possibility of gainful employment in less demanding jobs. However, the current disability system rewards sickness and dysfunction and discourages patients from resuming work.

Observations on the responsiveness of human subjects to human growth hormone. Effects of endogenous growth hormone deficiency and myotinic dystrophy.

The effect of human growth hormone (HGH) on the N, P, Na, and K balance, and on the body weight (BW) of three groups of subjects was measured. In group I were nine cases (age 6-69) with HGH deficiency; in group II, eight cases (age 9-79) with normal endogenous HGH; in group III, four cases with myotonic dystrophy (age 45-51). After a 7 day control period, the hormone was administered for 7 days. Each subject was tested with three doses of HGH: dose A, 0.0168 U/kg BW(3/4) per day; dose B, 0.0532 U/kg BW(3/4) per day; dose C, 0.168 U/kg BW(3/4) per day. In group I, the responsiveness to HGH declined with age. Two subjects aged 6 yr responded to all three doses of HGH with positive balances in N, P, Na, and K and increases in BW. At ages 15-17, responses were obtained only to doses B and C in three cases, and only to dose C in two cases. Two subjects, aged 42 and 69, responded only to dose C. Not only did the threshold dose increase with age in group I, but the magnitude of the responses declined with age as well.Patients of group II were less responsive to all doses of HGH than were patients of group I at comparable age. None responded to dose A or dose B. All responded to dose C, but the increments in balances and in BW stimulated by this dose were only one-third to one-half as great as in HGH-deficient subjects of similar age. Three patients of group III responded to all three doses of HGH, and one responded to doses B and C. The responses were similar in magnitude to those in the 6-yr old HGH-deficient children, and greater than those in all other subjects studied. These data show that responsiveness to exogenous HGH rises with deficiency of endogenous HGH, and that individuals with myotonic dystrophy are hyperresponsive to exogenous HGH.
