- Original description
A randomized controlled trial will be conducted at the Department of Physiotherapy, Dr. Ziauddin Hospital and Al-Rayaz Hospital, Karachi, Pakistan. A total of 150 patients diagnosed with knee osteoarthritis, aged between 40-60 years, will be recruited through a non-probability purposive sampling technique. Written informed consent will be obtained from all eligible participants prior to enrollment. The participants will be randomly allocated by the help of computer generated randomization sheet, into two groups i.e. experimental and the control group, with 75 participants in each group. Group A (experimental group) will receive diagonal proprioceptive neuromuscular facilitation (PNF) pattern exercises, while Group B (control group) will receive conventional strength training exercises. Heat therapy will be administered to both groups. All participants will be assessed using a standardized assessment form. Outcome measures will include pain intensity, knee range of motion, functional disability, hamstring flexibility, dynamic balance, and fatigue level. A single blinded assessor will assess all participants at baseline and at post intervention. Treatment sessions will be given thrice a week on alternate days for 6 weeks.Read full original descriptionShow less
