- Brief Summary
The objective of this randomized control trial is to evaluate the effectiveness of dynamic soft tissue mobilization in comparison with the proprioceptive neuromuscular facilitation (hold-relax) technique in reducing hamstring muscle tightness, pain and improving physical functions in patients with knee osteoarthritis by using Visual Analog Scale-10 cm, Active Knee Extension Angle Test in degree and Knee Injury and Osteoarthritis Outcome Score. This study will be carried out at Sindh Institute of Physical Medicine and Rehabilitation and Dow Institute of Physical Medicine and Rehabilitation, Dow University of Health Sciences, Karachi on the basis of non-probability purposive sample technique with screening for study criteria through a consultant physician (blinded) . After taking informed consent all participants will be randomly allocated into 2 groups i.e. 24 in interventional group 'A' and 24 in interventional group 'B' through second researcher who is not involved in screening, baseline assessment and providing intervention.The interventional group 'A' will received dynamic soft tissue mobilization on hamstring muscle along with cryotherapy on knee joint and isometric strengthening exercises for knee osteoarthritis while the interventional group 'B' will received proprioceptive neuromuscular facilitation (hold relax) technique on hamstring muscle along with cryotherapy on knee joint and isometric strengthening exercises for knee osteoarthritis. Twelve sessions will be given each of 30 minutes.Outcomes will be assessed at baseline and at last session.
- Detailed Description
All the participants will referred by the physiatrist as diagnosed with knee osteoarthritis. All the data will be collected within ethical constraints. Only principal investigator will access to the data as it will be in her custody. Patient recruitment, data collection, data management, data analysis, reporting for adverse events, and change management will be strictly performed within codes of ethics.
The sample size of 48 patients (24 in one group) is calculated by using open epi software version 3, Paired Means Power Analysis with 99% Confidence Interval and 95% power of test, mean ± S.D of VAS 5.27 ± 0.8 in group A and 3.81±1.4 in group B on the basis of previous findings. The missing data will be considered during analysis and results interpretation for any inconsistency in results.Data were stored and analyzed using IBM-SPSS version 23.0, Mean with standard deviation will be calculated for all quantitative variables. Counts with percentages will be presented for quantitative variables. parametric or non parametric tests will be used to compare outcome variables within and between groups after sessions completion. P-values less than 0.05 will be considered statistically significant.

- Primary Outcome Measures
Name Time Method Visual analogue scale in centimetre upto 4 weeks A bidirectional scale for subjective measurement for pain comprises of a 10 cm line labeling parallel on both sides, starts with least "no pain" (0 cm) and end on most "worst pain" (10 cm).
Active Knee Extension Angle Test in degree upto 4 weeks It will used to assessing the hamstring muscle length by using goniometry with 90° of hip flexion. higher the degree higher will be the knee extension.
- Secondary Outcome Measures
Name Time Method The Knee Injury and Osteoarthritis Outcome Score upto 4 weeks It is a patient related outcome measure, having 5 sub-scales, designed to check disease development and outcomes followed by surgical, pharmaceutical, physical therapy or other interventions.100 indicates no problem and 0 indicates extreme problem.
