Gait classification in a population of adults with hereditary spastic paresis

BACKGROUND

Classification of gait in adults with hereditary spastic paresis is limited. Our aim was to use a previously established system to classify gait.

METHODS

Forty-nine participants were retrospectively recruited and grouped into existing classifications based on sagittal plane knee joint kinematic data extracted from a 3D analysis. Waveform analysis was used to compare the grouped data to determine if and where differences in the subjective classifications appeared.

FINDINGS

Classification of gait patterns in adults with hereditary spastic paresis is successful. Differences between groups in line with the classification system were confirmed by statistical analysis. Crouch gait is illustrated by a flexed knee throughout stance phase. Recurvatum gait is dominated by knee hyperextension in mid-late stance. Stiff-knee gait demonstrates limited knee range of motion in stance and jump-knee gait is characterised by less knee flexion in early and mid-stance phase than all groups. Sagittal plane hip and ankle kinematics compliment group differences at the knee joint. The jump-knee group is more flexed at the hip than all groups during loading response phase and mid-stance; and the recurvatum group is more extended at the hip than the crouch, jump-knee, and stiff-knee groups during mid and late-stance phase. There is less ankle dorsiflexion throughout stance phase in the recurvatum group than in all other groups.

INTERPRETATION

Sagittal plane knee joint kinematic data can be subjectively used to classify gait features in adults with hereditary spastic paresis. Novel analysis show hip and ankle sagittal plane kinematics can be used to further assist classification.

Physiotherapists Prefer Clinical Supervision to Focus on Professional Skill Development: A Qualitative Study

Purpose: We explored physiotherapists' perceptions of clinical supervision. Method: Individual semi-structured interviews were conducted with a purposive sample of 21 physiotherapists from a public hospital. Qualitative analysis was undertaken using an interpretive description approach. The Manchester Clinical Supervision Scale (MCSS-26) was administered to evaluate the participants' perceptions of the effectiveness of the clinical supervision they had received and to establish trustworthiness in the qualitative data by means of triangulation. Results: The major theme was that the content of clinical supervision should focus on professional skill development, both clinical and non-clinical. Four subthemes emerged as having an influence on the effectiveness of supervision: the model of clinical supervision, clinical supervision processes, supervisor factors, and supervisee factors. All sub-themes had the potential to act as either a barrier to or a facilitator of the perception that clinical supervision was effective. Conclusions: Physiotherapists reported that clinical supervision was most effective when it focused on their professional skill development. They preferred a direct model of supervision, whereby their supervisor directly observed and guided their professional skill development. They also described the importance of informal supervision in which guidance is provided as issues arise by supervisors who value the process of supervision. Physiotherapists emphasized that supervision should be driven by their learning needs rather than health organization processes.

Direct supervision of physiotherapists improves compliance with clinical practice guidelines for patients with hip fracture: a controlled before-and-after study

Purpose: To determine if the addition of direct supervision to usual clinical supervision practice of physiotherapists can improve compliance with clinical practice guidelines and post-surgical outcomes for inpatients with hip fracture.Methods: A controlled before-and-after study was conducted on two acute orthopedic wards. Junior and mid-level physiotherapists on one ward were provided with direct supervision during their post-operative management of patients with hip fracture. Physiotherapists on the comparison ward received usual reflective supervision. The primary outcome was patient compliance with the hip fracture guideline to mobilize on the day following surgery. Secondary patient outcomes included physical function on the fifth post-operative day.Results: Data were collected from 290 patients with acute hip fracture. Patients at the direct supervision site were more likely to mobilize on the day after surgery [OR 3.14, 95% confidence interval (CI) 1.41-7.01; p = 0.005] and by the second post-operative day (OR 4.62, 95% CI 2.31-9.23; p < 0.001) compared to patients at the comparison site. Patients walked further on the fifth post-operative day (p < 0.001) with less assistance from therapists (p = 0.044).Conclusions: The addition of direct supervision improved physiotherapists' compliance with hip fracture guidelines and walking endurance and independence in hospitalized patients with hip fracture.Implications for rehabilitationThe addition of a direct supervision model, where physiotherapists are directly observed in their management of patients with hip fracture, to usual practice supervision improved early mobilization of patients with hip fractureDirect supervision appears to be an effective guideline implementation strategy that can improve care and outcomes for hospitalized patients with hip fracture.

The association between effectiveness of clinical supervision of allied health professionals and improvement in patient function in an inpatient rehabilitation setting

Purpose: Clinical supervision is widely accepted as an important element of practice for allied health professionals to ensure a high quality of patient care. However, it is unknown whether effective clinical supervision of allied health professionals improves patients' outcomes. This study investigated whether effective clinical supervision of allied health professionals is associated with improved patient functional independence. Methods: A prospective longitudinal study design and multi-level regression analysis were used to explore the association between effective clinical supervision and patient functional independence. The effectiveness of clinical supervision was assessed using the Manchester Clinical Supervision Scale. Functional improvement in patients treated by allied health professionals was measured utilising the mobility and self-care subscales of the functional independence measure.Results: Physiotherapists (n = 27) and occupational therapists (n = 26) in inpatient rehabilitation were recruited and the medical records of their patients (n = 1846) audited. The effectiveness of clinical supervision of physiotherapists was positively associated with improvement in personal care. Therapist variables accounted for less than 2.5% of the variation in patient improvement in functional independence.Conclusions: Effectiveness of a reflective model of clinical supervision of physiotherapists and occupational therapists was not associated with an improvement in their patients' mobility or personal care, respectively.Implications for rehabilitationEffective clinical supervision of physiotherapists and occupational therapists using a reflective model of practice is a poor predictor of improved functional independence in rehabilitation inpatients.Patient variables, such as the intensity of therapy, were more important predictors of patient functional improvement than effective clinical supervision.Initiatives aimed at increasing intensity of therapy will likely have a greater effect on improving patient functional independence compared with initiatives aimed at improving the effectiveness of clinical supervision using a reflective model of practice.Initiatives to improve the effectiveness of clinical supervision in improving quality of care could explore the use of a direct model of practice where supervisors directly observe and support supervisees during patient treatment sessions.

Validity and reliability of the 20-m run, horizontal leap, and four-bound tests measuring high-level mobility in neurologically impaired patients

Background

High-level mobility (HLM) training including running forms an integral part of physical rehabilitation for neurologically impaired patients.

Objective

This study examines the validity and reliability of three quickly administrable measures of HLM, namely, the 20-m run, horizontal leap, and four-bound tests in patients with neurological disorders.

Methods

This is a retrospective data audit of 62 patients (23 women, 37.1%; 39 men, 62.9%) participating in the HLM (running retraining) task. All participants were recovering from neurological conditions such as stroke, brain injury, brain/spinal tumour, Guillain-Barré syndrome, and cerebral palsy complications.

Results

High levels of test-retest reliability of the investigated tests (interclass correlation coefficient > 0.95) were obtained. The 95% minimum detectable changes were as follows: 20-m run, 1.9 seconds; horizontal leap, 0.20 m; four-bound test, 0.57 m. The area under the receiver-operated characteristic curve was 0.96 for the 20-m run, 0.90 for the horizontal leap, and 0.91 for the four-bound test, which suggests high validity of the tests to discriminate between participants who were classified as "running" and those as "not running". Participants performing at < 7.2 seconds for the 20-m run test or ≥ 0.75 m for the horizontal leap test or 4.0 m for the four-bound test were most likely classified as running.

Conclusion

The 20-m run, horizontal leap, and four-bound tests are valid and reliable objective measures of HLM when administered in people with neurological conditions.
