“…In another study, in which muscle activities during curl-ups performed at different trunk flexion angles were examined, greater flexion angle induced more activity of the upper RA, while a reduced flexion angle was advantageous for activating the lower RA ( Kim et al, 2015 ). More recently, Lee et al (2016) suggested that restriction of neck flexion could generate greater activity of the RA and external oblique (EO) abdominis ( Lee et al, 2016 ).…”

Recent studies have indicated that applying different breathing pattern and changes of extremity positions could be a useful way of performing challenging exercises that include coactivation of the abdominal muscles. The aim of this study was to investigate the effects of changes of breathing pattern and hip position on abdominal muscle activity during curl-up exercises. Surface electromyography responses of the rectus abdominis (RA), internal oblique (IO), external oblique (EO) muscles and rectus femoris (RF), and Borg rating of perceived exertion (Borg RPE) score were investigated during the curl up exercises. A total of 20 healthy, physically active male volunteers completed two hip positions (45° and 90° hip flexion) and three breath types (slow expiration, maximal inspiration, and maximal expiration) for curl-up variations. The curl-up with 90° of hip flexion significantly increased the muscular activities of IO, EO, RF, and Borg RPE score (P<0.05). The curl-up with maximal expiration significantly elevated the IO and EO activity, compared to other breathing conditions. There were no significant difference in RA activities (P>0.05). The present study showed both the hip position and breathing pattern affect abdominal muscle activities during the curl-up exercise, especially of the oblique muscles. Among the breathing patterns investigated herein, the curl-up with maximum expiration produced greater activation of the oblique muscles compared to slow expiration and maximum inspiration.

“…The "OTAGO exercise programme" (Campbell et al, 1997) is an individually tailored programme that was originally designed to be carried out in a client's home by a physiotherapist or trained instructor. Park and Chang (2016) conducted a small study (N = 8) on the effectiveness of the "OTAGO" on the falls efficacy, quality of life and activities of daily living (ADLs) of older adults who had experienced a stroke. This was carried out by two occupational therapists alongside four exercise assistants in the USA.…”

“…The study found statistically significant improvements with fear of falling, but non-significant results with quality of life and ADL functioning. However, Park and Chang's (2016) sample consisted of a small group (N = 8) of older adults who had experienced a stroke, potentially limiting the generalisability of the results to all community-dwelling older adults who are at risk of falling. Nevertheless, Thomas et al (2010) have shown that the "OTAGO" reduces the risk of death and rate of falls in older adults living in the community by 35 per cent, while Carande-Kulis et al (2015) conducted a cost-benefit analysis and concluded that the "OTAGO" provided positive net benefits.…”

Purpose As one ages, the risk of experiencing a fall increases and poses a number of serious consequences; 30 per cent of individuals over 65 years of age fall each year. Evidence-based falls prevention programmes demonstrate efficacy in reducing the rate and risk of falls among older adults, but their use in Irish occupational therapy practice is unknown. This study aims to investigate the implementation of falls prevention programmes by occupational therapists working with older adults in Ireland. Design/methodology/approach A cross-sectional survey was used to gather data on the use of falls prevention programmes among occupational therapists working with older adults in any clinical setting across Ireland. Purposeful, convenience and snowball sampling methods were used. The Association of Occupational Therapists of Ireland acted as a gatekeeper. Descriptive statistics and summative content analysis were used to analyse quantitative and qualitative data, respectively. Findings In all, 85 survey responses were analysed. Over 85 per cent of respondents reported “Never” using any of the evidence-based falls prevention programmes. The “OTAGO” Exercise Programme was the most “Frequently” used programme (9.5 per cent, n = 7); 29 respondents reported using “in-department” developed falls prevention programmes and 14 provided additional comments regarding current falls prevention practices in Ireland. Originality/value In the absence of Irish data on the subject, this study provides a benchmark to describe the use of evidence-based falls programmes by Irish occupational therapists with older adults.

Background and Purpose: Prolonged mechanical ventilation can greatly increase morbidity and mortality. Diaphragm weakness has been identified as a major contributor for 50% of patients; however, other muscles besides the diaphragm contribute to efficient ventilatory function. The purpose of this study was to compare the change in deoxyhemoglobin (ΔHHb) and muscle oxygen saturation (ΔSmO2) (markers of muscle recruitment) of 3 extra-diaphragmatic muscles across 4 different bed exercises. Methods: Using a pretest–posttest design, healthy participants (n = 18) performed 3 minutes of 30 repetitions of 4 exercises: resisted trunk flexion (TF), resisted neck flexion (NF), expiratory threshold loading (ETL), and neuromuscular electrical stimulation (NMES) of the rectus abdominis and external obliques. Near infrared spectroscopy was used to measure ΔHHb, and ΔSmO2 in the sternocleidomastoid, rectus abdominis, and external obliques during these exercises. Results: Increases of ΔHHb were highest for the sternocleidomastoid during NF and for rectus abdominis and external obliques during TF (P < .010). The opposite pattern was shown for ΔSmO2; decreases of ΔSmO2 were largest for the sternocleidomastoid during NF and for rectus abdominis and external obliques during TF (P < .005). No significant differences were observed in ΔHHb and ΔSmO2 for rectus abdominis and external obliques during ETL versus NF or NMES nor were there differences when comparing NF versus NMES for these 2 muscles. Conclusion: TF and NF are most effective for recruiting abdominal muscles and sternocleidomastoid, respectively, whereas ETL showed a variable response. Stimulation parameters of NMES and its tolerance can limit outcomes.
