Plantar pressure gradient and pressure gradient angle are affected by inner pressure of air insole.

Clinically, air insoles may be applied to shoes to decrease plantar pressure gradient (PPG) and increase plantar gradient angle (PGA) to reduce foot ulcers. PPG and PGA may cause skin breakdown. The effects of different inner pressures of inflatable air insoles on dynamic PPG and PGA distributions are largely unknown in non-diabetics and people with diabetes. This study aimed to explore the impact of varying inner air insole pressures on PPG and PGA to establish early mitigation strategies for people at risk of foot ulcers. A repeated measures study design, including three air insoles (80 mmHg, 160 mmHg, and 240 mmHg) and two walking durations (10 and 20 min) for a total of six walking protocols, was tested on 13 healthy participants (height, 165.8 ± 8.4 cm; age, 27.0 ± 7.3 years; and weight, 56.0 ± 7.9 kg, BMI: 20.3 ± 1.7 kg/m^2) over three consecutive weeks. PPG, a measurement of the spatial variation in plantar pressure around the peak plantar pressure (PPP) and PGA, a variation in the gradient direction values at the three plantar regions, big toe (T1), first metatarsal head (M1), and second metatarsal head (M2), were calculated. This study indicated that PPG was lower at 80 mmHg air insoles after 20 min of walking in the M1 region (p = 0.010). The PGA in the M2 increased at an air insole of 80 mmHg compared to 240 mmHg (p = 0.015). Compared to 20 min, the 10 min walking duration at 240 mmHg of air insole had the lowest PPG in the M1 (p = 0.015) and M2 (p = 0.034) regions. The 80 mmHg air insole significantly lowered the PPG compared to a 160 mmHg and 240 mmHg air insole. Moreover, the 80 mmHg air insole significantly decreased PPP and increased PGA compared to the 160 mmHg and 240 mmHg air insole. A shorter walking period (10 min) significantly lowered PPG. The findings of this study suggest that people with a higher risk of foot ulcers should wear softer air insoles to have a lower PPG, as well as an increased PGA.

The effects of different inner pressures of air insoles and walking durations on peak plantar pressure.

BACKGROUND: Exercise reduces chronic complications in individuals with diabetes and peripheral vascular diseases. In clinical practice, the use of air insole may reduce peak plantar pressure (PPP), and risk for diabetic foot ulcers (DFUs). However, there is no guideline on selecting air insole pressure for effectively reducing PPP. Therefore, this study aimed to investigate the effects of different air insole pressure on PPP at different walking durations. METHODS: We tested 13 participants using repeated measures study design, including 3 air insole pressures (80, 160, and 240 mm Hg) and 2 walking durations (10 and 20 minutes) for 6 walking conditions. PPP values at the first toe, first metatarsal head, and second metatarsal head were calculated. RESULTS: The one-way ANOVA showed significant pairwise differences of PPP at 20 minutes duration in the first metatarsal head between 80 and 240 mm Hg (P = .007) and between 160 and 240 mm Hg (P = .038); in the second metatarsal head between 80 and 240 mm Hg (P = .043). The paired t test confirmed that walking duration significantly has lower PPP at 10 minutes than 20 minutes with 240 mm Hg air insole in the first metatarsal head (P = .012) and the second metatarsal head (P = .027). CONCLUSION: People at risk of foot ulcers are suggested to wear shoes with 80 mm Hg of air insole for reducing PPP in the first metatarsal head and the second metatarsal head. Moreover, people may avoid wearing the stiffer insole (240 mm Hg) for more than 20 minutes.

Religious Practices and Spiritual Well-Being of Schizophrenia: Muslim Perspective.

Purpose: To explore religious activities and its functions on the spiritual wellbeing of Muslim patients with schizophrenia. Patients and Methods: Semi-structured in-depth interviews were conducted in six schizophrenia inpatients and two female nurses. Document analysis of the standard operating procedure related to patients' spiritual needs fulfilment and patients' medical records were also undertaken in order to triangulate data and to get insights about patient spiritual and religious activity. Thematic analysis was used to analyse data. Results: Five themes and 12 sub themes were revealed from the study data. The five themes elicited from the study namely frequency, timing, barriers to perform religious activities, impact on health status and negative effects if not performing the religious activities. Religious activities such as salat and dhikr for schizophrenia inpatients are still performed five times a day and when they are not getting period. Feeling upset, restless, happy, grateful, and when they are missing their family was the common reason why patients perform the religious activities. The main barriers to performing salat and dhikr for example: insufficient prayer tools and Al-Qur'an, as well as patients' physical conditions. Religious activities such as salat and dhikr positively impact patients' physical and mental health status, mindfulness, and concentration. Negative impacts physical and emotional are released when patients did not perform salat and dhikr. Conclusion: The findings show that salat and dhikr which perform on time and regularly have a positive impact on the physical and mental health of schizophrenia inpatients. The author might recommend the mental health hospital provide adequate worship or prayer equipment (gown and Al-Qur`an) for patients.
