Abstract Context: Foam rolling has recently been used frequently to increase flexibility. However, its effects on proprioception, strength and motor performance are not well known. In addition, very few studies have examined the effects of foam rolling in the upper extremity. Objective: To investigate the effects of foam rolling on elbow proprioception, strength, and functional motor performance in healthy individuals. Design: Randomized controlled study. Setting: Exercise laboratory of X Department, X University. Patients or Other Participants: Sixty healthy participants (mean age=22.83±4.07 years). Intervention(s): We randomly assigned participants into two groups: the foam rolling group (FRG) (4 weeks of foam rolling for the biceps brachii muscle) and control group (CG) (no foam rolling). Main Outcome Measure(s): We evaluated proprioception (joint position sense [JPS] and force matching), biceps brachii muscle strength, and functional motor performance (modified pull-up test [MPUT], closed kinetic chain upper extremity stability test [CKCUEST], and push-up test) at the baseline, and at the end of the 4th week and 8th week. Results: JPS at 45° elbow flexion, muscle strength, CKCUEST, and push-up test results improved after foam rolling and improvement was maintained at the follow-up (p<0.017). While the changes in groups for the results of proprioception and CKCUEST were similar among the three time points (p>0.05), there were significant improvements for the muscle strength from baseline to the second evaluation, and from baseline to the follow-up (p<0.001) in the FRG compared to the CG (p=0.004). The FRG was superior to the CG in the improvement of push-up test results among the three time points (p=0.040, p=0.001, p<0.001). Other data did not change (p>0.05). Conclusion: Foam rolling is effective in improving elbow JPS in small flexion angles, biceps brachii strength, and some parameters of upper extremity functional motor performance. These effects are maintained 4 weeks after application.

Botulinum Toxin Injections

Spastic muscles are weak muscles. It is known that muscle weakness is linked to poor motor performance. Botulinum neurotoxin (BoNT) injections are considered as the first-line treatment for focal spasticity. The purpose of this study was to quantitatively investigate the effects of BoNT injections on force control of spastic biceps brachii muscles in stroke survivors. Ten stroke survivors with spastic hemiplegia (51.7 ± 11.5 yrs; 5 men) who received 100 units of incobotulinumtoxinA or onabotulinumtoxinA to the biceps brachii muscles participated in this study. Spasticity assessment (Modified Ashworth Scale (MAS) and reflex torque) and muscle strength of elbow flexors, as well as motor performance assessment (force variability of submaximal elbow flexion) were performed within one week before (pre-injection) and 3~4 weeks (3-wk) after BoNT injections. As expected, BoNT injections reduced the MAS score and reflex torque, and elbow flexor strength on the spastic paretic side. However, motor performance remained within similar level before and after injections. There was no change in muscle strength or motor performance on the contralateral arm after BoNT injections. The results of this study provide evidence that BoNT injections can reduce spasticity and muscle strength, while motor performance of the weakened spastic muscle remains unchanged.

Aim. To determine the effects of vibration therapy devices exposure with a constant and aperiodic frequency of vibrations on the tissue of the biceps muscle of the shoulder. Material and methods. The study was conducted on 10 volunteers aged 24-35 years. the program Adobe Audition CC 2020, the device for vibration therapy with a constant vibration frequency “Charm 1-t”, the device for vibration therapy with an aperiodic vibration frequency “Individual massager with a pseudo-boiling layer” (MI EPS), the robotic biomechanical diagnostic and training complex with biological feedback CON-TREX were used. The measurement of the maximum strength of the biceps brachii muscle was carried out once to detect sensitivity to vibration, and then during 7 days for the dynamics of power characteristics. The maximum force was measured before exposure to vibrotherapy devices and immediately after exposure using the isokinetic classical mode of operation of the diagnostic system. Results. In a single measurement of biceps strength on one shoulder in a group of women, the average increase in muscle strength after using the Charm 1-T device was 0.8 N (2.3%), after using MI EPS – 1.9 N (6.4%). In the group of men, the average increase in muscle strength after using the device “Charm 1-T” was 1.9 N (3.2%), after using “MI EPS” – 4.6 N (7.2%). At the seven-day follow-up, the average increase in strength in the group of women on the right hand after using the Charm 1-T device was 21.8% (5.6 N), on the left hand after using MI EPS, the increase was 23.2% (6.1 N). In the group of men, the average increase in strength on the right hand after using “Charm 1-T” was 53% (30.7 N), on the left hand after using “MI EPS” – 15.5% (11.5 N). Conclusion. All participants in the study groups were determined to be sensitive to both types of vibration exposure. The study participants demonstrated an increase in strength indicators when testing the biceps muscle of the shoulder, and there was also an improvement in the tolerability of the procedure itself.

Background A transection of the short head of the biceps brachii muscle is an uncommon injury seen among outpatient sports physical therapy clinics. The highest rate of occurrence and the majority of literature that discusses this specific injury are related to US military parachuting. The purpose of this case report is to outline the episode of care from 2 days after the injury through 6 months of conservative treatment, which consisted of therapeutic exercise, manual therapy, and cryotherapy, within an outpatient sports physical therapy clinic in a military setting. Case Description This case report outlines the initial evaluation, diagnostic imaging, treatment, and 6-month follow-up measures for a 23-year-old male patient who sustained a static line injury resulting in a full-thickness tear of his biceps brachii muscle and a partial tear of the coracobrachialis muscle. Outcomes The individual described in this case report reported having no functional limitations in regard to his job and leisure activities or any pain at his 6-month follow-up, with a score of 0% noted on his Shortened Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH). Isokinetic testing revealed a 39.1% decrease in elbow flexion peak torque and a 60.8% decrease in elbow flexion total work output at this same follow-up interval. Discussion In determining the appropriate course of treatment for this injury type, conservative physical therapy intervention should be considered as a viable treatment option, as there have been no decisive studies to suggest superior outcomes with other methods such as surgical correction. It is further recommended that research be conducted in an effort to prevent such injuries from occurring, as this mechanism of injury has proven to be much higher among the US military population compared with other military populations.

Objectives. To evaluate the association between inflammatory biomarkers, neurotrophic factors, birth conditions, and the presence of motor development abnormalities in preterm neonates. Methods. Plasma and urinary levels of cytokines (IL-1β, IL-6, IL-10, TNF, and IL-12p70), chemokines (CXCL8/IL-8, CCL2/MCP-1, CCL5/RANTES, CXCL10/IP-10, and CXCL9/MIG), and neurotrophic factors (BDNF and GDNF) were evaluated in 40 preterm neonates born between 28 and 32 incomplete weeks of gestation, at four distinct time points: at birth (umbilical cord blood) (T0), at 48 (T1), at 72 hours (T2), and at 3 weeks after birth (T3). Biomarkers levels were compared between different time points and then associated with Test of Infant Motor Performance (TIMP) percentiles. Results. Maternal age, plasma, and urinary concentrations of inflammatory molecules and neurotrophic factors were significantly different between groups with normal versus lower than expected motor development. Higher levels of GDNF were found in the group with lower than expected motor development, while IL-1β and CXCL8/IL-8 values were higher in the group with typical motor development. Conclusion. Measurements of cytokines and neurotrophic factors in spot urine may be useful in the follow-up of motor development in preterm neonates.

Background: Technology is prevalent in almost every aspect of life, from handheld phones to computers. Increases in cervical flexion can cause a strain on the neck and muscles of the upper extremity. Objective: To examine the effect of 30 minutes of cervical flexion at 45 degrees. It was hypothesized that muscle strength will decrease after flexion, and there would be no significant differences between dominant and nondominant arms or genders. Study design: Twenty-four participants (12 male, 12 female) (n = 24; height = 173.1 + 9.3 cm; weight = 73.33 + 22.58kg) were measured before and after cervical flexion using a MicroFET2 Hand Held Digital Muscle Tester to test the middle deltoid, biceps brachii, and triceps brachii of each arm. Results: Compared to pre-measures significant differences were found in both middle deltoids and both biceps brachii, but not in either triceps brachii (p < 0.05). Overall no limited significant differences were found between genders of muscles of either arm. Significant differences (p < 0.05) were found in the dominant biceps brachii, non-dominant biceps brachii, dominant triceps brachii, dominant deltoid, and non-dominant deltoid. Conclusion: These results suggest that a normal daily degree of cervical flexion will decrease some upper extremity strength over the course of 30 minutes.
