Effectiveness of fingertip light contact in reducing postural sway in older people.

BACKGROUND AND OBJECTIVE: haptic cues from fingertip light touch (LT) with a stationary surface reduce postural sway even at non-mechanically supportive force levels. Aim of this study was to determine the effects of LT on postural sway in older compared with younger persons. SUBJECTS: twenty young (age 20-29, mean 23.9 + 2.5) and 20 older participants (age 65-83, mean 74.3 + 6.4). METHODS: subjects stood in the semi-tandem position on a firm surface, and their postural sway was quantified using a force platform. Experimental trials, randomised across subjects, included two sight conditions (vision and no vision) and three contact conditions (no touch, NT; light touch, LT; and force touch, FT). The measured parameters were the length and the area of centre of pressure sway (COP-L and COP-A) and the mean velocity of COP displacements in the anterior-posterior (COP-AP) and medial-lateral (COP-ML) direction. RESULTS: for all variables, the analysis showed significant differences between contact conditions, sight conditions and age. Contact-age interaction was significant between NT and LT conditions, with older participants showing greater decrease in postural sway than younger participants, but not between FT and LT conditions. CONCLUSIONS: results indicate that the effectiveness of LT in reducing postural sway may be greater in older than in younger persons, perhaps because in older persons haptic cues from upper extremity might counterbalance sub-clinical sensory loss in the lower extremities. This finding supports the hypothesis that older people may sometimes use a walking aid as an informative device and suggests that during balance training external aids should not be used.

The scale for contraversive pushing: A reliability and validity study.

OBJECTIVE: Pushing toward the hemiplegic side can interfere with mobility training after stroke. This study estimated the internal consistency, interrater reliability, and validity of the Scale for Contraversive Pushing (SCP). METHODS: Twenty-six patients with recent stroke were diagnosed with pusher behavior (PB). Two testers, randomly selected from 3 other examiners, independently assessed each patient using the SCP on the same day within 3 days of admission for rehabilitation. Cohen kappa coefficient was used to determine the agreement between the clinical and SCP diagnosis. The interrater reliability of the scale was estimated by calculation of the intraclass correlation coefficient. Cronbach's alpha coefficient and Pearson's coefficients were used to estimate the internal consistency of the scale and correlations between the subscores and the total score. RESULTS: The agreement between SCP and clinical diagnosis was very low when the original cutoff criterion for SCP diagnosis was used but was almost perfect with a modified criterion. The interrater reliability was good to excellent with regard both to each sub-score and to the total score. The internal consistency was very high, along with correlations between subscores and total score of the scale. CONCLUSIONS: The results provide support for use of the SCP based on its reliability and validity using a modified cutoff criterion to make a diagnosis of PB.

Motor and functional recovery in patients with post-stroke depression.

PURPOSE: Depression is very common following stroke. Correlation between post-stroke depression (PSD) and functional outcome has been shown, but differential impact both on functional and motor recovery has not been deeply investigated. This study evaluates the influence of PSD on motor and functional outcome. METHOD: One hundred and seventeen acute stroke patients were selected in an intensive rehabilitation department, and divided into two groups according to the presence of PSD (PSD+ and PSD-). Screening measures were DSM-IV criteria, the Geriatric Depression Scale and the Cornell Scale. Outcomes were evaluated on the basis of the Barthel Index (BI) and the Fugl-Meyer Assessment Scale (FMA). Measurements were performed at admission to the department T1), discharge (T2) and follow up (T3) in a whole period of 3 months from stroke. RESULTS: Both groups showed a significant improvement in all outcome measures. Improvement differences were not significant on FMA scores in either group at each assessment; the PSD group had a significant higher improvement on BI score at follow-up. According to the logistic model, from T1 to T2 and from T1 to T3, only motor recovery shows a significant relation with functional recovery; from T2 to T3 PSD is the only significant factor related to functional recovery. CONCLUSIONS: PSD is not an influencing factor for motor recovery. Results show a negative impact of PSD on the functional recovery process after discharge and not during hospitalisation. Discharge appears to be critical step for management of PSD.

Physiotherapy for pusher behaviour in a patient with post-stroke hemiplegia.

OBJECTIVE: This case report describes a specific, literature-based physiotherapy treatment and the outcome for a stroke patient with pusher behaviour. Pusher behaviour is characterized by pushing strongly towards the hemiplegic side in all positions and resisting any attempt at passive correction of posture to bring the weight towards or over the midline of the body. METHODS: The patient was a 71-year-old man with clear pusher behaviour due to a stroke. Therapy for the pushing behaviour was performed over a 3-week period. Motor function, mobility, disability, tone anomalies and pusher behaviour were assessed before and after the study period. Immediate effects of a single training session were assessed by clinical observation. RESULTS AND CONCLUSION: Immediate effects on the pusher behaviour were observed when using visual and auditory feedback, but not when somatosensory input was used. These results were not maintained to the end of the treatment period. Treatment makes the patient able to use compensatory strategies for functional activities. The long-term effects should be investigated in more depth in the future.

Physiotherapy based on the Bobath concept for adults with post-stroke hemiplegia: a review of effectiveness studies.

The Bobath concept, also known as neurodevelopmental treatment, is a widely used approach in the rehabilitation of hemiparetic subjects in many countries. Despite 50 years of clinical use its effectiveness is questionable. This paper aims to examine whether there is evidence to accept neurodevelopmental treatment as an effective approach. A systematic literature search was undertaken. Fifteen trials have been selected and classified according to a 5-level hierarchic scale of evidence for clinical interventions. Results show no evidence proving the effectiveness of neurodevelopmental treatment or supporting neurodevelopmental treatment as the optimal type of treatment, but neither do methodological limitations allow for conclusions of non-efficacy. Methodological aspects of selected studies are discussed and requirements for further research are suggested.

Glenohumeral subluxation in hemiplegia: An overview.

This review summarizes the recent advances in glenohumeral subluxation (GHS) in hemiplegic patients and analyzes the reliability and validity of clinical evaluation and the effectiveness of different treatment approaches. GHS, a common complication of stroke, can be considered an important risk factor for shoulder pain and other problems. GHS is a complex phenomenon, and its pathomechanics are not yet fully understood. Radiographic measurements are considered the best method of quantifying GHS. Clinical evaluation can be useful as screening assessment. Functional electrical stimulation and strapping are effective in an acute stage of hemiplegia; some types of slings have been shown to be effective and may be used together with other strategies.
