    RELATIONSHIP OF DAILY TIME SPENT OUTDOORS WITH SLEEP QUALITY AND EMOTIONAL WELL-BEING AMONG COMMUNITY-DWELLING OLDER ADULTS DURING COVID-19 RESTRICTIONS

    Introduction: Given the recent constraints imposed due to the ongoing COVID-19 pandemic and the importance of the daily light-dark cycle for entraining the human circadian system, it is possible to state that the elderly are likely to be at serious risk of experiencing sleep-related problems. Whilst reduced or limited time outdoors, and thus, exposure to diurnal bright light appear to be detrimental to sleep and emotional well-being in old age, further research is required to confirm this relationship. Materials and Method: To build on earlier work, a two-week study was conducted in a sample of 79 community-dwelling older adults recruited by using snowball sampling method. Throughout the study, the participants were allowed to be outdoors from 10.00 a.m. to 1.00 p.m. on weekdays. Whilst the participants were performing their daily habitual activities, they were asked to keep an activity diary and report on their sleep quality and emotional wellbeing using two questionnaires. Results: The results demonstrated that participants' daily time spent outdoors (49.13 minutes on average) positively correlated with their perceived sleep quality and emotional well-being at various - but significant - levels (p<0.05). Moreover, significant negative correlations were identified between participants' sleep quality and experienced emotional disturbances (p<0.001). Conclusion: Based on the research findings, it is reasonable to conclude that spending momentary periods outdoors may have adverse consequences for the elderly. To maintain a healthy sleep-wake cycle and alleviate related emotional problems in old age, increasing outdoor time and diurnal bright light exposure should be encouraged.

    Time Difference Between Onsets of Lateral and Medial Hamstring Muscles During Gait in Patients With Patellofemoral Pain: a Preliminary Study
    (Marmara Univ, inst Health Sciences, 2022) Coskunsu, Dilber Karagozoglu; Can, Filiz; Kuchimovs, Shavkat; Akalan, Nazif Ekin; Kilicoglu, I. Onder; Ozturk, Necla; Kuchimov, Shavkat; Kılıçoğlu, Önder İsmet
    Objective: Early activation of lateral hamstrings (LH) relative to medial hamstrings (MH) has been thought to be the cause of abnormal knee abduction and external rotation of the tibia, which affects the orientation of patellar tendon and increases lateral patellofemoral compression. Therefore, early activation of LH relative to MH is considered to have a role in the patellofemoral pain (PFP). The aim of this study was to investigate the time difference between MH and LH onsets in patients with PFP during gait. Methods: Thirteen patients with bilateral PFP (mean age 28.73 +/- 7.44 years) and 13 asymptomatic subjects (mean age 30.47 +/- 6.22 years) were recruited in the study. Gait analysis was performed using the ELITE system (BTS, Milano-Italy) with video cameras (TVC, BTS, Milano-Italy). Participants were requested to walk at a self-selected speed on a force platform, and EMG data were recorded from MH and LH muscles for 10 initial contacts by using TELEEMG (BTS, Milano-Italy). Time difference between the onsets of the MH and LH was calculated for each initial contact by using moving averaging method, then their mean was obtained for each participant. Results: The time difference between onsets of MH and LH was - 26.9 +/- 22.2 ms for PFP subjects and - 11.2 +/- 14.2 ms for control subjects, and LH mainly became activated earlier compared to MH in most of the subjects in both groups. There was a statistically significant difference between the time differences of the groups (p=0.041). Conclusion: Our findings suggest that LH displayed an earlier activation in subjects with PFP compared to control subjects during gait.
