Core Strengthening Versus Lower Limb Proprioceptive Neuromuscular Facilitation Techniques in Chronic Stroke Patients
Stroke is a global healthcare issue that causes increased death rates. Good trunk stability is essential for balance and extremity use during daily functional activities and higher-level tasks. The anticipatory activity of trunk muscles is impaired in stroke patients. The trunk is the central column of the body; therefore, proximal trunk control is a prerequisite for distal limb movement control, balance, and functional activities. The purpose of the study is to highlight the most appropriate rehabilitation technique for trunk stability.
Full Title of Study: “Comparative Effects of Core Strengthening Versus Lower Limb Proprioceptive Neuromuscular Facilitation Techniques on Trunk Function and Balance in Chronic Stroke Patients”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: Single (Investigator)
- Study Primary Completion Date: March 15, 2023
A randomized clinical trial will be performed in which 42 patients with strokes will be included. The data will be collected from Riphah Rehabilitation center Lahore and Ittefaq hospital Lahore. Consecutive sampling technique will be used to collect data. The duration of the study will be 10 months. Trunk impairment scale and berg balance scale will be used as the data collection tool. Data collection will be started after taking informed consent from all the patients. Patients will be allocated to intervention groups by randomization. The patients in group A will be given core strengthening exercise for 4 weeks. The patient in group B will be given PNF exercise for the treatment of trunk for 4 weeks. After data collection analysis of pre and post values will be done by using SPSS version 25.
- Other: core strengthening exercises
- The core muscles training includes transverse abdominis, multifidus, paraspinals, quadratus lumborum, and obliques.
- Other: Proprioceptive Neuromuscular Facilitation
- lower limb PNF technique along with conventional treatment i.e., Rhythmic initiation, slow reversal, stabilizing reversal, and combination of isotones.
Arms, Groups and Cohorts
- Experimental: core strengthening exercises
- Participants will be positioned in supine. first stage participants will be taught to activate abdominal wall musculature. They will be initially trained to perform abdominal bracing. Then positioned in quadruped position and asked to lift alternate arms, gradually progressing to alternate leg lifts and alternate arm/leg raises to activate multifidus. Then side bridges (side plank) exercise for activation of quadratus lumborum and obliques. Then asked to perform trunk curls in crook lying, asking them to lift their upper trunk slightly (15°) from the plinth, hold the position for 5 sec. Perform 30 repetitions of each exercise with 8-sec hold. Maintain normal diaphragmatic breathing throughout the intervention
- Experimental: Proprioceptive Neuromuscular Facilitation
- Rhythmic initiation (RI) Patients progressively performed voluntary relaxation, passive movements, active assisted, active resisted movements and than active movements. Dynamic reversals (slow reversals) Isotonic contractions of first agonists and then antagonists performed against resistance was performed initially. Stabilizing reversals Isotonic contractions of first agonists, then antagonists against resistance was performed in an alternate way. Mixture of isotonic (agonist reversals, AR) resisted concentric, contraction of agonist muscles moving with the range was performed progressively following eccentric, lengthening contraction, moving slowing to the start position. . Total 30 min for 3 days a week for a total duration of 4 weeks was set as a optimal time frame duration. Each technique was given for 10 min.
Clinical Trial Outcome Measures
- Berg balance scale
- Time Frame: 4th week
- Changes from baseline Berg balance scale is used to objectively determine a patient’s ability (or inability) to safely balance during a series of predetermined tasks. It is a 14-item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function and takes approximately 20 minutes to complete. It does not include the assessment of gait.
- Trunk Impairment Scale (TIS)
- Time Frame: 4th week
- Changes from baseline TIS is a new tool to measure motor impairment of the trunk after stroke. The TIS evaluates static and dynamic sitting balance as well as co-ordination of trunk movement.
