Data entry workers perceptions and satisfaction response to the "stop and stretch" software program.
ABSTRACT Cumulative Trauma Disorder (CTD) is a collection of chronic musculoskeletal disorders caused by frequent, sustained, and repetitive movements, most notably by computer usage at the workplace. A computer based break reminder program (Stop and Stretch) has been developed and installed to prevent CTDs caused by prolonged computer usage at the workplace. We investigated users' opinions to the Stop and Stretch program at their work place. 19 computer users were recruited as the subjects of the study. We conducted a survey after all the subjects used the Stop and Stretch program for one month. Among the nineteen subjects, 52.5% or 10 noticed a difference of symptoms after using the program; 63.3% or 12 thought the program had positive effect on their productivity; 100% or all 19 thought the program was easy to follow; 100% or all 19 thought it was helpful; 94.7% or18 were satisfied with the program; and the same value would recommend the program to others. When grouped into those who had prior experience with using stretch and exercise as part of their work routine15 subjects had no prior experience; and 14 participants within that group were satisfied or very satisfied with the program; 93.3% or 14 would recommend it to co-workers; and over half of those 15 thought the program is easy to use. The study provided insight to the response to using "stretch break software" and provided indicators of satisfaction with the Stop and Stretch program and that the program had sufficient usability and acceptance within a workplace setting which might be applied in other work settings similar to these.

ABSTRACT: The product of heart rate (HR) and systolic blood pressure (SBP) provides a convenient estimate of myocardial oxygen consumption (MVO2). This study aimed to explore calisthenic exercise-induced changes in MVO2 in healthy normotensive subjects. Eleven college-female students were recruited for this study. They performed one upper extremity and one lower-extremity one-minute calisthenic exercise. Each exercise was practiced with slow, moderate and fast cadences. Values of pre- and post-exercise HR and SBP were used to calculate pre- and post-exercise rate pressure product (RPP) (RPP= HR X SBP). Percentage of change between pre- and post-exercise RPP (% “ RPP) was used to estimate the calisthenic exercise-induced changes in MVO2 (% “ RPP= [(Post -exercise RPP- Pre - exercise RPP) ÷ Pre-exercise RPP] X 100). One-minute calisthenic exercise resulted in increased post-exercise RPP estimating increase in MVO2 demand. This increase was influenced by the three selected exercise cadences (P value is 0.029 for upper-extremity and 0.0001 for lower extremity). Results observed that more MVO2 is required with lower-extremity calisthenic exercise than with upper extremity exercise. Progressive increase in the % “ RPP was found through the three cadences and it was of no significance in upper-extremity exercise (P = 0.208) and significance in lower-extremity exercise (P = 0.023). In conclusion, One-minute calisthenic exercise revealed minimal exercise-induced changes in MVO2 for normotensive healthy female college-students especially with upper-extremity. If convalescing cardiac patient would show the same response, One-minute calisthenic exercise with its three cadences would be supported as a low intensity and safe exercise for Phase I cardiac rehabilitation.

ABSTRACT: The physical intervention discussed here is task-related training combined with trunk restraint to limit motor compensation during reaching-and-grasping training. Children and adults with hemiparesis use excessive trunk movement to compensate for limitations in arm movement during reaching activities. Reaching and grasping with physical limitation of trunk movements (trunk restraint) leads to improvements in the quality of arm motor patterns (shoulder and elbow) and of upper-limb function. The intervention consists of task-oriented upper-limb therapy performed while movements of the trunk are limited by strapping the trunk to the back of a chair. The trunk restraint limits forward and lateral trunk displacement and rotation but allows scapular movement.

ABSTRACT: Botulinum Neurotoxin A (BoNT-A) is a useful medication for the reduction of spasticity and dystonia in the upper limb of children with cerebral palsy (CP). The method of toxin delivery, dose, and muscle selection criteria are established. Children who are being treated require appropriate assessment at the impairment and activity levels of functioning. Once injected, children require specific therapy delivered by an occupational therapist (OT) according to the specified goals of the intervention set out, prior to injection, by the child, family, and health care workers. Botulinum neurotoxin injection offers the child with cerebral palsy a window of opportunity in which to develop further skills in upper limb functioning. Further research using rigorous scientific design evaluating specific therapy regimes and other interventions is required to enable more specific protocols to be established. After injection and intensive therapy, the client was really happy to be able to catch and throw a ball with his school friends.
