Shoulder rehabilitation strategies, guidelines, and practice.

This framework for rehabilitation is consistent with the proximal-to-distal kinetic chain biomechanical model and applies current concepts of motor control and closed chain exercises. This framework approaches the final goal--glenohumeral motion and function-through facilitation by scapular control, and scapular control through facilitation by hip and trunk activation. This article supplies guidelines for rehabilitation and practices to implement the guidelines that have proved effective in our hands. Other protocols may be effective, as long as they adhere to several basic concepts of kinetic chain-based shoulder rehabilitation: 1. Functional shoulder rehabilitation requires that the muscle activations and joint motions follow a proximal-to-distal pathway along the appropriate kinetic chain. 2. Muscles around the shoulder function in an integrated fashion and should be rehabilitated in integrated patterns. Specific muscles may need isolated activation, but this activation should be facilitated by placing the proximal segments in a facilitating function. 3. Scapular control and coupled rotator cuff activation is vital to normal shoulder function. 4. Closed chain axial loading exercises are the primary means of early shoulder rehabilitation and are the mainstays of functional rehabilitation protocols.

A kinetic chain approach for shoulder rehabilitation.

OBJECTIVE: To introduce an approach to shoulder rehabilitation that integrates the kinetic chain throughout the rehabilitation program while providing the theoretical rationale for this program. BACKGROUND: The focus of a typical rehabilitation program is to identify and treat the involved structures. However, in activities of sport and daily life, the body does not operate in isolated segments but rather works as a dynamic unit. Recently, rehabilitation programs have emphasized closed kinetic chain exercises, core-stabilization exercises, and functional programs. These components are implemented as distinct entities and are used toward the end of the rehabilitation program. DESCRIPTION: Kinetic chain shoulder rehabilitation incorporates the kinetic link biomechanical model and proximal-to-distal motor-activation patterns with proprioceptive neuromuscular facilitation and closed kinetic chain exercise techniques. This approach focuses on movement patterns rather than isolated muscle exercises. Patterns sequentially use the leg, trunk, and scapular musculature to activate weakened shoulder musculature, gain active range of motion, and increase strength. The paradigm of kinetic chain shoulder rehabilitation suggests that functional movement patterns and closed kinetic chain exercises should be incorporated throughout the rehabilitation process. CLINICAL ADVANTAGES: The exercises in this approach are consistent with biomechanical models, apply biomechanical and motor control theory, and work toward sport specificity. The exercises are designed to stimulate weakened tissue by motion and force production in the adjacent kinetic link segments.

Influences of age, performance, and item relatedness on verbatim and gist recall of verb-noun pairs.

Age differences in adults' memory for performed actions (e.g., wave hand) are sometimes smaller than age differences in memory for nonperformed phrases. In this study, we examined the conditions under which performance reduces age differences in recall. Younger and older adults performed or read verb-noun phrases that were either related (e.g., actions performed in a kitchen) or unrelated. Performance did not reduce age differences in recall of the exact verbs and nouns used to describe an action, but performance did reduce age differences in memory for the gist of related actions. Older adults especially had difficulty recalling the exact verb used to describe the action. These results suggest that older adults may have better memory for actions than is revealed by tests of verbatim recall. They may remember performing the action but not remember the exact words used to describe the action.

Nurses perspective of patient acuity on geriatric assessment units.

The purpose of this study was to explore how nurses on geriatric assessment inpatient units perceived patient acuity. Three questions were developed and included: what variables do nurses use to define acuity; does variation exist between and among groups of nurses; and are there nursing activities taken for granted or overlooked that can contribute to the perception of acuity? The purposive sample included all the full time and part time nurses (11 RNs, 16 LPNs) working on the units. Focus groups were used to facilitate the data gathering for this qualitative study. Five themes were identified from the data and the program NUD*IST was used to visualize the relationships between the individual items and themes. Patient acuity was defined differently by the RNs and LPNs and is based on their reality and the realm of their mandated practice. A large category of indirect non patient related activities was found to contribute greatly to the nurses' perception of acuity. Two benefits of the study were: 1) provision of a breakdown of items nurses incorporate into their definition of acuity; 2) a list of categories to guide decision making when determining which category of staff is required to best meet the needs of the patients.
