The effects of Bobath-based trunk exercises on trunk control, functional capacity, balance, and gait: a pilot randomized controlled trial.

OBJECTIVE: The aim of this study was to investigate the effects of Bobath-based individually designed trunk exercises on trunk control, upper and lower extremity function, and walking and balance in stroke patients. The main aim of treatment was to eliminate individual trunk impairments during various patient functions. METHODS: The study was planned as an assessor-blinded, randomized controlled trial. A total of 22 patients volunteered to participate in the study. Trunk function, functional capacity, and gait were assessed with the Trunk Impairment Scale (TIS), stroke rehabilitation assessment of movement (STREAM), and a 10-m walking test, respectively. The Berg Balance Test (BBT), functional reach (FR), and timed up-and-go (TUG) tests were used to evaluate balance. After the initial assessment, the patients were divided randomly into two groups, the study group (12 patients) and the control group (10 patients). The mean age of the patients in the study group was 55.91 years (duration of stroke 58.66 months) and that of the control group was 54.00 years (duration of stroke 67.20 months). Individual training programs were determined for the patients in the study group, taking into consideration their evaluation results; and strengthening, stretching, range of motion, and mat exercises were determined for the control group according to their functional level. The participants in both groups were taken into the physiotherapy program for 12 weeks, 3 days a week for 1 hour a day. RESULTS: In group analyses, both groups showed improvement in STREAM, TIS, and TUG tests. Only the study group produced significant gains in the BBT, FR, and 10 m walking tests (P < 0.05). According to the pre- and post-treatment results, no significant difference was observed in any of the evaluated parameters between the two groups (P>0.05). CONCLUSION: Individually developed exercise programs in the Bobath concept improve trunk performance, balance, and walking ability in stroke patients more than do conventional exercises.

A reliability of the prototype trunk training system for sitting balance.

[Purpose] Cerebral palsy is a disorder that affects balance in the sitting position. Cerebral palsy patients need trunk muscle strengthening and balance training. In order to improve trunk control sensory-motor control training is carried out on an unstable surface. We have developed a Trunk Training System (TTS) that can provide visual feedback using a tilt sensor for balance training in the sitting position. Before using the TTS for training children with cerebral palsy experiments were conducted with healthy adult subjects and the TTS to gather basic data for its improvement. [Subjects] The subjects were 11 healthy men (n=3) and women (n=8). [Methods] Subjects trained at two levels (5°, 10°), in four different directions (anterior, posterior, left, right), three times each. TTS outcome indices (stability index, performance time) were measured. [Results] The stability index and performance time showed high correlation (-0.6

Effects of trunk training using motor imagery on trunk control ability and balance function in patients with stroke.

OBJECTIVE: To explore the effects of trunk training using motor imagery on trunk control and balance function in patients with stroke. METHODS: One hundred eligible stroke patients were randomly divided into a control group and trial group. The control group was given routine rehabilitation therapy, while the trial group was given routine rehabilitation therapy and trunk training using motor imagery. RESULTS: Prior to treatment, there was no significant difference between the two groups (P > 0.05) in Sheikh's trunk control ability, Berg rating scale (BBS), Fugl-Meyer assessment (FMA), movement length, movement area, average front-rear movement speed, average left-right movement speed, and surface electromyography (sEMG) signal of the bilateral erector spinae and rectus abdominis. After treatment, Sheikh's trunk control ability, FMA, and BBS in the two groups were significantly higher than those before treatment (P < 0.05). The movement length, movement area, the average front-rear movement speed, and the average left-right movement speed in the two groups decreased significantly (P < 0.05). The differences of these indicators between the two groups were statistically significant (P < 0.05). After treatment, the rectus abdominis and erector spinae on the affected side of the two groups improved when compared with those before treatment (P < 0.05). The rectus abdominis and erector spinae on the healthy side of the trial group descended after treatment (P < 0.05), while little changes were observed on the healthy side of the control group after treatment (P > 0.05). The rectus abdominis and erector spinae on the affected side of the trial group improved when compared with those in the control group (P < 0.05). There was no significant difference between the two groups in the decline of abdominalis rectus and erector spinal muscle on the healthy side. CONCLUSION: Trunk training using motor imagery can significantly improve the trunk control ability and balance function of stroke patients and is conducive to promoting the recovery of motor function.

Effect of Trunk Targeted Interventions on Functional Outcomes in Children with Cerebral Palsy- A Systematic Review.

Objective of this review was to collate information on the effectiveness of trunk targeted intervention on children with cerebral palsy (CP) on three functional outcomes that are gross motor function, trunk control and balance. A comprehensive search was conducted on online databases from inception to August 2021, using relevant keywords. A total of 15 randomized controlled trials which enrolled children with cerebral palsy under 18 years met the inclusion criteria. A significant improvement was seen in the trunk targeted training groups on applying trunk targeted interventions. Trunk targeted interventions improve gross motor function, trunk control as well as balance, hence should be incorporated in the conventional physical therapy program delivered to children with CP and would help in greater functional recovery.

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.

The effects of the three-dimensional active trunk training exercise on trunk control ability, trunk muscle strength, and balance ability in sub-acute stroke patients: A randomized controlled pilot study.

BACKGROUND: Trunk control ability has been identified as an important early predictor of functional recovery after stroke. OBJECTIVE: Our study aimed to investigate the effects of three-dimensional active trunk training exercise on trunk control ability, trunk muscle strength, and balance ability in sub-acute stroke patients. METHODS: Twenty-four sub-acute stroke patients were randomly assigned to an experimental (n= 12) or control (n= 12) group. The experimental group (EG) performed three-dimensional active trunk training exercises using the Space Balance 3D system, while the control group (CG) performed only general trunk training exercises five times per week, for a total of three weeks. The Trunk Impairment Scale (TIS), trunk muscle strength, balance ability using the Space Balance 3D system, and Brunel Balance Assessment (BBA) scores were assessed before and after the intervention. RESULTS: Pre-to-post intervention improvement was noted in all outcome measures for both groups (p< 0.05). Post intervention, the TIS, trunk muscle strength, static balance, and BBA scores were significantly higher in the EG than those in the CG (p< 0.05). CONCLUSION: Our study suggests that the three-dimensional active trunk training exercise may be more effective compared to the general trunk training exercise in improving trunk control ability, trunk muscle strength, and balance ability in sub-acute stroke patients.

Effects of Trunk Exercise on Unstable Surfaces in Persons with Stroke: A Randomized Controlled Trial.

Background: Improving balance-related ability is an important goal in stroke rehabilitation. Evidence is needed to demonstrate how this goal could be better achieved. Aim: Determine if trunk exercises on unstable surfaces would improve trunk control and balance for persons in the subacute stage of stroke. Design: An assessor-blind randomized controlled trial. Setting: Inpatients in the department of rehabilitation in a general hospital. Population: Patients who suffered a first-time stroke with onset from one to six months. Methods: Inpatients with stroke were assigned to upper limb exercises (control group, n = 17) or trunk exercises on unstable surfaces (experimental group, n = 18) to receive training twice a week for six weeks, in addition to their daily conventional stroke rehabilitation. Sensorimotor function tests, including hand grip, plantar sensitivity, stroke rehabilitation assessment of movement and Fugl-Meyer lower extremity motor scale, and clinical outcome assessments, including Trunk Impairment Scale and 6 m walk test, were conducted before and after six weeks of training. The center of the pressure area while maintaining static posture and peak displacement while leaning forward, as well as the average speed of raising the unaffected arm, were measured in sitting without foot support, sitting with foot support and standing to reflect trunk control, sitting balance and standing balance, respectively. Results: The between-group differences in the sensorimotor functions were nonsignificant before and after training. Compared with the control group, the experimental group had significantly greater forward leaning and faster arm raising in sitting without foot support, higher Trunk Impairment Scale total score, and shorter 6 m walking time after training, but not before training. Conclusion: Trunk exercises on unstable surfaces could further improve trunk control, the ability to raise the unaffected arm rapidly in sitting, and walking for persons in the subacute stage of stroke. This intervention may be considered to be included in stroke rehabilitation.

Effects of reinforced trunk training on the motor function of hemiplegic patients caused by stroke / 中华物理医学与康复杂志

Objective To study the effects of reinforced trunk training on the motor function of stroke patients. Methods Fifty patients were randomly divided into the reinforced trunk training group and the control group. All patients were regularly treated with drug, electrotherapy, acupuncture, massage, physical therapy (PT) and occupational therapy (OT). The patients in the reinforced trunk training group were administered with trunk function training in addition to the above interventions. The Rivermead Motor Index (RMI) assessment and the Modified Barthel Index (MBI) assessment were used to assess the motor function of the patients. Results Motor scores of both groups were significantly increased ( P
