How to evaluate effects of occupational therapy – lessons learned from an exploratory randomized controlled trial

OBJECTIVES To evaluate the efficacy of OT and the validity of different outcome-parameters to reflect efficacy, including gold-standard clinical rating scales and quantitative motor assessments. METHODS 40 patients were included in an exploratory, randomized-controlled, single-blinded trial, receiving either (I) ten weeks of OT, with a main focus on motor aspects of activity limitations and a ten-week follow-up assessment or (II) no intervention. Inclusion criteria were diagnosis of PD and Hoehn & Yahr stage 2-3. Patients with major depression, other neurological or orthopedic diseases or OT beforehand were excluded from the study. To monitor treatment effects the MDS-UPDRS part II and III were used for patient- and clinician-based assessment. Objective Pegboard as well as Q-Motor "tremormotography" and "digitomotography" were applied. RESULTS The interventional group reported a subjective amelioration of activity limitations, with a significant improvement of MDS-UPDRS part II at the end of the study (p = 0.030). However, clinician's rating and quantitative motor assessment failed to detect a significant improvement of motor impairment and fine motor control. CONCLUSIONS This study goes in line with previous trials, showing an individual improvement of activity limitations from the patients' point of view. The discrepancy between self-perception, focusing on activity limitation, and clinician-based rating, focusing on motor impairment, challenges the current gold standard assessments as valid outcome parameters for occupational therapy trials aiming for an individualized improvement of disease burden.

The earth air pipe heat exchanger (EAPHE) control the ventilation air temperature using the geothermal heat energy of the earth. In this paper experimental set up of earth air pipe heat exchanger (EAPHE) installed to find the performance analysis of ventilated air at different operating conditions. The performance analysis of earth air pipe heat exchanger(EAPHE) done by varying the various parameters like air velocity, mass flow rate, depth of the pipe and material of the pipe etc. The results obtained revealed that the temperature inside the earth can be increased by 8-10 0 C during winter season and can be decreased by 12-13 0 C during summer seasons compare to air atmospheric temperature. In this work the main work is to implement the water jacket around the pipe at the exit sec...
Sustainable Adsorption Method for the Remediation of Crystal Violet Dye Using Nutraceutical Industrial Fenugreek Seed Spent

To access the adsorption capacity, the factors affecting it are kinetics and the equilibrium thermodynamics. All the experiments were designed at approximately pH 7. The adsorption isotherm model proposed by Langmuir fits better than the Freundlich isotherm model. Kinetic studies data confirm the pseudo-second order model. It is evident from thermodynamic parameter values that the process of adsorption is endothermic, physical and dynamic. The process optimization of independent variables that influence adsorption was carried out using response surface methodology (RSM) through bi-level fractional factorial experimental design (FEED). The analysis of variance (ANOVA) was implemented to investigate the combined effect of parameters influencing adsorption. The...
