Background: Ballistic action of throwing exerts eccentric load on the rotator cuff causing frequent micro trauma. Proper throwing mechanics and an appropriate training program, minimizes the stress on the glenohumeral joint maximizing performance. The purpose of this study was to assess the role of physical factors affecting effective and efficient throwing. This could help in both screening and further training the individual or directing more focus to the throwing technique.Method: 80 subjects participated. Manual muscle testing was used to assess the shoulder muscles and back extensors while Modified isometric stability test was used for lumbar core muscles. Throw distance was measured in sitting to focus on the shoulder joint. Spearman's rank order correlation test was used for statistical data analysis.
Results: Infraspinatus, Pectoralis major, lumbar core and Back extensor muscles showed statistically significant values to throw distance measured. Supraspinatus, Subscapularis, Latissimus dorsi and Deltoid showed a positive correlation though not statistically significant.
Conclusion: All physical factors have a positive correlation to throw distance. Thus, training these can possibly improve a throw and help in injury prevention.

Backrground: 30-60% of patients with stroke have no arm function.Spasticity causes hyperactivity in those muscles that can lead to decreased activity of their antagonists. Thus biceps spasticity can cause reduced control of triceps amounting to reduced reach function which is usually an important therapeutic goal. Some studies have evaluated efficacy of electrical stimulation (ES) on spasticity.
Aims: Purpose of the trial was to assess effect of stimulation of triceps on forward reach distancein stroke patients.
Settings and Design: Prospective, analytical, experimental, randomized and open trial done in Physiotherapy OPD of a tertiary care hospital.
Methods and Material: 50 post stroke patients, in the age group of 30 to 60year withspasticity of shoulder, elbow, wrist and hand muscles of affected extremity up to grade 2 on Ashworth Scale and Brunnstrom sequential recovery stage 3 or 4; were assessed for modified Tardieu Scale(MTS), active elbow extension range at elbow(AROM) and forward reach distance(FRD). They were randomly assigned to either of the Conventional (CG) or Experimental Group (EG). CG received motor training only whereas the EG received motor training and ES to triceps on affected upper extremity. After 3 weeks they were evaluated again for the above outcomes. Statistical tests were non-parametric tests as the data obtained was not normally distributed, as analyzed using Shapiro-Wilk test for normality. Wilcoxon Sign rank test for comparing medians in all 3 outcome measures. Mann Whitney test was also used to compare percent mean differences in both groups for all 3 outcome measures.
Results: FRD, AROM and MTS improved after 3 weeks in CG with significance of p-value of 0.0122 each and in experimental group with significance of p-value of 0.0121 each. FRD showed insignificant change between groups with p-value of 0.207. The mean percent difference in MTS, AROM and FRD was 0.007, 0.007 and 0.977 respectively.
Conclusions: Electrical Stimulation when given to the triceps muscle as an adjunct to the motor training has shown additional improvement in reducing the biceps spasticity, improving AROM but not significantly improving the FRD.

Background: In-vitro microscopic studies on nerve have shown adverse effects of tension on vascularity and conduction. Slider neurodynamic technique involves sliding of nerve without producing tension while tensioner involves elongation of entire nerve tract i.e. it produces tension. In view of potential negative effects of tension on vascularity and conduction, tensioner technique may have adverse effects or it may reduce the therapeutic benefits. Also owing to visco-elastic nature of neural tissue, understanding the lasting effect of these techniques will help in deciding frequency of treatment.
Purpose: Therefore, purpose of this study was to compare the immediate and lasting effects of slider and tensioner neurodynamic techniques on knee extension range and pain intensity during slump test in normal population.
Study design: Prospective comparative study.
Method: Slump test was performed on 110 normal asymptomatic subjects who demonstrated normal neurogenic response to slump test (17- 25yrs; slider group-55, tensioner group-55). Subjects in slider and tensioner group performed 10 repetitions of slider and tensioner neurodynamic techniques respectively in 2 minutes on first day. Knee extension range and pain intensity on VAS at 'onset of pain' and at 'pain tolerance' during slump test were measured in pre-intervention period and re-measured in immediate post, on 2nd day post and 1 week post intervention periods.
Results: Repeated measures Anova and Freidmann test showed significant improvement in knee extension range and pain intensity respectively during slump test in immediate post intervention period only in both groups. No significant difference was found on 2nd day and 1week post intervention periods. Comparison between the two groups showed statistically non-significant trend in knee extension range by unpaired t-test and pain intensity by Mann Whitney-u test on all days of assessment.
Conclusion: Both slider and tensioner techniques have positive and significant effect on improving knee extension range and pain intensity in slump position in normal asymptomatic subjects. Both the techniques are effective only in immediate intervention period with no carry over effect.
