Effects of the Immobilization of the Upper Extremities on Spatiotemporal Gait Parameters during Walking in Stroke Patients: A Preliminary Study

The effects of improvement in upper extremity function on gait and balance in children with upper extremity affected

BACKGROUND

This study aimed to investigate the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected.

RESEARCH QUESTION

What are the effects of functional improvement in the upper extremity on gait and balance in children with upper extremity affected?

METHODS

Eighteen children with a diagnosis of rheumatologic diseases and 15 healthy children were evaluated with Shriners Hospital Upper Extremity Assessment, Jebsen-Taylor Hand Function Test, Abilhand Rheumatoid Arthritis Scale, 10-meter walk test and Childhood Health Assessment Questionnaire. For static balance assessment, the Biodex Balance was used. Ground reaction forces (peak forces (heel strike and push-off) and minimum force (loading response), single-limb support duration, Center-of-Force displacement and walking speed were evaluated with the Sensor Medica. Arm swing was evaluated with the Kinovea 2D motion analysis.

RESULTS

Before treatment, single-limb support duration and push-off force was higher and center-of-force displacement was lower on affected side compared to unaffected side in rheumatologic group. After the 6-week rehabilitation program, upper extremity function, quality of life and functional gait score improved. Single-limb support duration decreased on affected side and increased on unaffected side. On affected side, push-off force decreased. The arm swing parameters were similar before and after treatment.

SIGNIFICANCE

Improving upper extremity function can help with gait balance by decreasing the difference in walking and balance parameters between the affected and unaffected sides and providing for more symmetrical weight transfer.

Correlation analysis of balance function with plantar pressure distribution and gait parameters in patients with cerebral infarction in the basal ganglia region

Objective

To analyze the correlation between balance function and gait parameters of patients with basal ganglia infarction. And to observe the influence of balance function on plantar pressure and hemiplegia gait based on the Berg Balance Scale (BBS) score.

Methods

One hundred and forty patients with cerebral infarction hemiplegia in the basal ganglia region (a study group, n = 140) and healthy people (a control group, n = 140) were enrolled. The study group was evaluated with the BBS, the 10 m walking test (10MWT), and the timed up-and-go test (TUGT). The gait parameters and the peak plantar pressure were measured in both groups while walking, and the differences between the groups were compared. In addition, the characteristics of the plantar pressure curve of the hemiplegic and non-hemiplegic sides during walking and the correlation between the 10MWT, the TUGT, the plantar pressure peak, the gait parameters,and the BBS score were analyzed in the study group.

Results

The peak plantar pressure of the forefoot and heel, stride length, lateral symmetry, stand phase, swing phase, and dual stand phase of both sides in the study group were significantly lower than those in the control group (P < 0.05). The BBS score negatively correlated with the 10MWT, the TUGT, the peak plantar pressure of the hemiplegic forefoot, midfoot, and the non-hemiplegic midfoot, the anterior to posterior position (ant/post position), hemiplegic stand phase, and the dual stand phase (P < 0.05). The BBS score positively correlated with the hemiplegic swing phase and stride length (P < 0.05).

Conclusion

A correlation was found between the forefoot plantar pressure and the stand phase of the hemiplegic limbs, the ant/post position, and the balance function after basal ganglion cerebral infarction. This association can be used in walking and balance assessment for stroke rehabilitation. Correcting forefoot pressure or the front and ant/post position can improve balance function.

Does immobilization of the shoulder in different positions affect gait?

BACKGROUND

The shoulder joint is immobilized in various positions after injury or reconstructive operative intervention. It is not clear how these immobilization positions in the shoulder joint affect gait.

RESEARCH QUESTION

Does the immobilized shoulder joint in different positions following shoulder surgery or injury affect gait?

METHODS

A total of 38 healthy individuals with a mean age of 25.94 years and BMI of 25.66 kg/m², underwent gait analysis in 4 different immobilized positions and normal gait. Gait parameters were evaluated using the GAITRite electronic walkway, and to determine symmetry, the bilateral spatiotemporal gait parameters were calculated using the Symmetry Index. Repeated-measures one way analysis of variance was used to compare the walking parameters in different positions.

RESULTS

Velocity, step length and stride length were significantly decreased, and step width and single support time were increased in some immobilized positions (p < 0.05). Differences in asymmetry were determined in the gait parameters of the immobilized positions but not significantly. When the shoulder was immobilized in abduction, step width asymmetry tended to increase but it was not significant.

SIGNIFICANCE

This cross-sectional simulation study may be important in demonstrating the clinical changes of gait in injuries, pathologies, and postoperative rehabilitation that require the immobilization of the shoulder joint. It could be recommended that arm swing is included in gait rehabilitation, gait and balance training can be provided to patients after shoulder immobilization.
