Trunk training following stroke

Effect of a Home-Base Core Stability Exercises in Hereditary Ataxia. A Randomized Controlled Trial. A Pilot Randomized Controlled Trial

BACKGROUND

Core stability exercises (CSE) have been shown to be effective in improving trunk function in several neurological diseases, but the evidence is scarce on Hereditary Ataxias (HA).

OBJECTIVE

To evaluate the effectiveness of a 5-week home-based CSE program in terms of ataxia severity, trunk function, balance confidence, gait speed, lower limb motor function, quality of life, health status and falls rate in HA individuals at short- and long-term.

METHODS

This is an assessor-blind randomized controlled clinical trial parallel group 1:1. The individuals were divided in experimental group (EG) performed standard care in addition to CSE, and control group (CG) performed standard care alone. The CSE home-program was conducted 1-h/day, 5-day/week for 5-week. The assessment was performed at baseline, endpoint (5-week), and follow-up (10-week). The primary outcomes were ataxia severity assessed by the Scale for the Assessment and Rating of Ataxia and trunk function assessed by Spanish-version of Trunk Impairment Scale 2.0. The secondary outcomes were balance confidence assessed by Activities-specific Balance Confidence (ABC), gait speed by 4-meter walk test (4-MWT), the lower limb motor function by 30-s sit-to-stand, quality of life by EuroQol 5-dimension 5-level (EQ-5D-5L), health-status by EQ-5D and falls rate.

RESULTS

Twenty-three HA individuals were recruited (51.8 ± 11.10 years). Statistically significant group-time interaction was shown in ABC (F:5.539; P = 0.007), EQ-5D-5L Total (F:4.836; P = 0.013), EQ 5D (F:7.207; P = 0.006).

CONCLUSIONS

No statistical differences between groups for ataxia severity and trunk function were observed. However, were differences for balance confidence, gait speed, quality of life, and falls rate in HA individuals.

Therapists and patients perceptions of a mixed reality system designed to improve trunk control and upper extremity function

A prototype system aimed at improving arm function and trunk control after stroke has been developed that combines mixed-reality (MR) feedback with a mobile seat system (Holoreach). The purpose of this study was to assess the usability of Holoreach in a rehabilitation setting from both the patient and therapist perspective. Ten therapists (eight physiotherapists and two occupational therapists) used the device in their regular therapy programs for fifteen stroke patients with trunk control issues. Each patient received four individual therapy sessions with the device performed under the supervision of the therapist. Therapists and patients kept therapy diaries and used customized questionnaires. At the end of the study two focus groups were conducted to further assess usability. Generally, the prototype system is suitable for training trunk and arm control. The therapists expressed overall positive views on the impact of Holoreach. They characterized it as new, motivating, fresh, joyful, interesting, and exciting. All therapists and 80% of the patients agreed with the statement that training with Holoreach is beneficial for rehabilitation. Nonetheless, improvements are required in the hardware and software, and design. The prototype system contributes at various levels to the rapidly evolving advances in neurorehabilitation, particularly regarding the practical aspect of exercise delivery.

Is trunk training effective at improving ability in activities of daily living and function of people who have had a stroke? A Cochrane Review summary with commentary

BACKGROUND

Effective trunk control is an essential component of sitting and standing balance, and is a key requirement for movement of the head and limbs, and for carrying out functional tasks. A stroke can result in impaired trunk control, affected by stroke-related deficits in balance, muscle function, coordination and position sense. Recovery of trunk control is recognised as a key goal of stroke rehabilitation.

OBJECTIVE

To evaluate the effectiveness of trunk training interventions in people with stroke.

METHODS

A summary of the Cochrane Review by Thijs et al. (2023), with comments from a rehabilitation perspective.

RESULTS

68 studies (2585 participants) were included in the Cochrane review. Trunk training was not found to have any benefit on measures of ADL, when compared to other dose-matched therapies, but did improve trunk function and other outcomes. Trunk training was more beneficial than non-dose-matched therapies for measures of ADL, trunk function, and other outcomes. The certainty of these findings is very low.

CONCLUSION

Evidence supports the use of trunk training as part of stroke rehabilitation. However certainty in these findings is very low due to volume, quality and heterogeneity of the evidence.
