Children with unilateral cerebral palsy (CP) exhibit abnormal movements due to atypical pelvic movements and weakness of trunk muscles. We investigated the effects of abdominal muscle strengthening and pelvic control exercises on trunk control, abdominal muscle thickness change rate, and pelvic movement in children with unilateral CP. Fourteen children with unilateral CP were randomly divided into two groups, and abdominal muscle strengthening and pelvic control exercises were applied to the experimental group, and general physical therapy was applied to the control group, 30 min per session, twice a week, for a total of 8 weeks, respectively.

Lumbopelvic pain (LBP) is a prevalent condition during pregnancy, affecting a significant proportion of pregnant women. It arises from hormonal, biomechanical, and postural changes, often exacerbating discomfort and impairing quality of life. This study aimed to evaluate the effects of targeted motor control interventions focusing on sternal alignment on spinal alignment, pain, and muscle activity in pregnant women at risk of preterm birth.

Background: Vojta method improves motor function by inducing a response by pressing the stimulus zones.

Purpose: To determine the effect of the stimulus zones on trunk muscle thickness, trunk control, trunk angle, and gross motor function in children with spastic-type cerebral palsy.

Methods: A quasi-experimental pilot study was conducted with 19 children with spastic-type cerebral palsy divided into two groups: Vojta method group (n = 10) and general physical therapy group (n = 9).

Article Synopsis
  • The study explores the impact of different sitting postures on postural problems, particularly slump sitting.
  • It compares a corrected sitting position—focused on lifting the sternum—to forced and passive positions among 270 participants aged 19-23 by measuring postural angles.
  • Results indicate that the corrected position shows a more stable range and positive lumbar lordosis, unlike the forced and passive positions, suggesting that proper posture correction is more effective in improving spinal alignment.

Developmental delays cover a wide range, with different movement characteristics occurring depending on differences in muscle tone. We aimed to investigate muscle activity and acceleration during sit-to-stand in developmentally delayed (DD) children with different muscle tones. Forty participants were divided into three groups: typically developing (TD) children (n=18), DD children with hypertonia (n=12), and DD children with hypotonia (n=10).

We investigated abdominal and lower extremity muscle activity and thickness in typically developing children and children with developmental delays. A total of 35 children participated: typically developing peers (n=13), children with hypotonia (n=10), and children with spasticity (n=12). Muscle activity and thickness were measured at rest and during activity.

(1) Background: Decreased trunk stability is accompanied by delay in motor development in children with central hypotonia. We investigated the effect of Vojta therapy on trunk control in the sitting position in children with central hypotonia. (2) Methods: In 20 children with central hypotonia, Vojta therapy was applied to the experimental group (n = 10) and general physical therapy to the control group (n = 10).

Purpose: In this study, the effect of the Vojta approach on neck stability and static balance in children with hypotonia was studied.

Methods: Seventeen children with hypotonia were randomly divided into the Vojta approach group (n=9) and the general physical therapy group (n=8). Each group was applied intervention for 30 minutes per session, 3 times a week, for a total of 4 weeks.

The development of motor function is related to the development of neural pathways in the white matter. Children with developmental delay (DD) and hypotonia have reduced motor function, and their neural pathways are observed differently from those of typically developed children. We investigated changes in neural pathways through diffusion tensor imaging (DTI) after utilizing the Vojta approach.

The old people are weakened and misaligned due to aging, and their balance and quality of life are reduced. We investigated that the effect of scapular strengthening exercise on balance and quality of life in the old people. A scapular strengthening exercise was applied to the experimental group, and the general conditioning exercise was applied to the control group for 40 min per session, 5 times a week, for a total of 4 weeks.

Stroke patients have limited motor function due to ankle spasticity, and various interventions are applied to solve this problem. The purpose of this study was to investigate the effects of functional electrical stimulation (FES) with ankle exercise on spinal cord motor neuron excitability and balance in stroke patients. Twenty-five stroke patients were divided into the three groups.

The restoration of motor function is important in daily life in patients with brain damage. Although attentional concentration can affect motor function, most physical therapists focus only on therapeutic exercise. Therefore, we investigated changes in motor function in patients with high attentional concentration during our intervention.

Increased use of smartphones can cause abnormal alignment of head and neck, resulting in forward head posture (FHP). This can lead to change in the structures and function of the cervical vertebrae. The purpose of this study was to determine the impact on deep neck flexor muscles, proprioception, vestibular function, and balance of subjects with induced FHP by using smartphone.

Background: The curl-up exercise is widely used in clinical practice for strengthening abdominal muscles, but has been applied without a systematic method.

Objective: The purpose of this study was to determine the most effective method considering the angle and muscle contraction direction during the curl-up exercise.

Methods: Fourteen healthy males performed the curl-up exercise according to contraction direction (concentric and eccentric) and angle (30∘, 60∘, and 90∘).

The purpose of this study was to examine the effects of Vojta approach on the gross motor function and diaphragm movement in children with spastic cerebral palsy (CP). Ten children with spastic CP were randomly assigned to a general physiotherapy group (trunk strengthening exercise and gait training) (n=5) and a Vojta approach group (n=5). Interventions were implemented for 30 min per time, 3 times a week for a total of 6 weeks.

The present study was conducted to investigate the effect of ankle strengthening exercise applied on unstable supporting surfaces on the proprioceptive sense and balance in adults with functional ankle instability. As for the study method, 30 adults with functional ankle instability were randomly assigned to an ankle strengthening exercise group and a stretching group on unstable supporting surfaces, and the interventions were implemented for 40 min. Before and after the interventions, a digital dual inclinometer was used to measure the proprioceptive sense of the ankle, the Balancia program was used to measure static balance ability, and the functional reach test was used to measure dynamic balance ability.
