EFFECTS OF CERVICAL MUSCLES STRENGTHENING WITH AND WITHOUT SHOULDER EXERCISES IN POST-MASTECTOMY PATIENTS WITH NECK PAIN

Background of the Study: To compare the effects of cervical muscles strengthening with and without shoulder exercises on post- mastectomy patients with neck pain. Methodology: It was a randomized clinical trial, conducted in physical therapy department of a clinical setting through Dynamometer. Sample size of 24 patients were taken. Non-probability convenience sampling technique was used. A written consent form was taken from patients meeting inclusion criteria and were randomly allocated. In one group, patients were treated with cervical Muscles strengthening with shoulder exercises. In other group, patients were treated with cervical Muscles strengthening alone. Treatment was given once a day for three weeks. Muscle strength was examined using dynamometer, Baseline data was taken before treatment on first day after inclusion in study and again on the last day after treatment. SPSS 25 was used to analyze the data. Results: Wilcoxon signed rank test was used to compare individuals within the group which showed significant results in both groups, p-value 0.000 (i.e. <0.001) for neck strength. Between groups comparison was done using Mann-Whitney U Test and it showed no significant changes for cervical extensors (p- value;0.143) , cervical side bending (right) (p-value; 0.315) and cervical side bending (left) (p-value; 0.853) strength differences, but however cervical flexors strength showed statistically significant results as p-value was 0.003. Conclusion: It was concluded that Cervical strengthening along with shoulder Rehabilitation can help improve the strength of cervical flexors. However, both the groups have equally resulted in improved cervical extensor, Side bending right and left strength.

Pollination Efficiency and Role of Managed Honeybees Apis Mellifera L. in Yield Response of Canola under Rainfed Conditions

Canola (Brassica napus L.) is an important oil seed crop in Pakistan having the potential of bridge gap between consumption and production of edible oil in the country. Canola has high potential of yield but due to many limiting factors, farmers in Pakistan are getting three times less production than developed countries. One of these factors is the insufficient crop pollination. Pollination is an essential ecosystem service andcan be provided by managed pollinators (honeybees and other insects). A two year study was designed to assess the possible role of Apis mellifera managed pollination to enhance the yield of Brassica napus in Gujar Khan, Rawalpindi during 2015 and 2016. Pollen sources of A. mellifera during blooming period of B. napus comprised of 11.11% ornamentals, 33.33% weeds, 22.22% shrubs, 22.22% herbs and 11.11% crops. Quantification of pollens transported by A. mellifera reflected maximum pollens of B. napus followed by Calendula officinalus and Sonchus asper. Studies about determination of colony level pollination efficiency of A. mellifera on B. napus crop depicted that on average maximum colony foraging rate of A. mellifera foragers with pollen loads (281.2 bees/ ten minutes) was observed at 1200 hours on 10-02-2015 (6th weekly interval). Weather factors influenced the activity of A. mellifera colony foraging rate in the field conditions. A. mellifera foragers with pollen loads attained maximum colony foraging activity on 10-02-2015 (6th weekly interval) when the temperature was 21.5 ̊C and average R.H. was 60%. Colony condition of A. mellifera varied throughout the blooming period of B. napus. Maximum brood and stored food area of bees were observed at the end week of B. napus blooming period. xxiv Observations were made about insect pollinators’ visited B. napus throughout the blooming period. Out of thirty five species belonging to five orders and twenty families were recorded. A. mellifera was most frequent visitor comprised 87.66%. Managed A. mellifera had significant effect on yield of B. napus in response to two different treatments. The results about total numbers of pods plant-1, numbers of seeds plant-1 and seed weight pods-100showed significant differences between treatments and revealed that treatment T2 (Open plot free visit of bees+ other pollinators) gave maximum yield as compared to treatment T1 (Cages plants without honeybees). Seed quality parameters of B. napus crop also affected bytwo different treatments (T1=Cages plants without honeybees, T2= Open plot free visit of bees+ other pollinators). Hive distances also affected on colony level pollination efficiency in A. mellifera on B. napus. Colony foraging rate at different hive distances from the B. napus crop proved that colony foraging rate of A.mellifera started to decrease after 200m hives distance. Maximum foraging rate of A. mellifera was at 100m hives distance from B. napus. Effect of beehives distance from B. napus on brood and food stored area of A. mellifera showed that maximum brood and stored food area was found in hives placed at 100m distance from B. napus crop. Overall recommendation for using managed A. mellifera as an important pollinator of B. napus proved that seed yield of B. napus increased with managed pollination of A. mellifera as well as brood and stored food area of A. mellifera also increased with blooming progression of B. napus.
