Summary

this study will be conducted to investigate the effect of low level laser therapy (LLLT) on wrist flexors spasticity and hand functions in patient with stroke

Detailed description

Spasticity is more often found in the flexors muscles of the upper limb (fingers, wrist, and elbow flexors) and extensor muscles of the lower limb (knee and ankle extensors). Wissel et al observed that spasticity developed most often in elbow (79%), wrist (66%), ankle (66%), and shoulder (58%).9 Lundstrom et al concluded that spasticity is observed more frequently in the upper extremities than in the lower extremities, and Urban et al found a higher degree of spasticity in the upper limb muscles. LLLT is thought to work through several mechanisms. Stimulating ATP production and increasing cellular energy. The therapy can cause vasodilation, improving circulation in the treated area. It may also reduce the production of inflammatory mediators and increase anti-inflammatory factors, while potentially stimulating the synthesis of growth-promoting factors that facilitate tissue healing, and renewal may be stimulated by this therapy. In the context of spasticity management, LLLT has garnered scientific interest as a possible intervention, although its efficacy remains under scrutiny .Hypothesized mechanisms of action include muscle tone reduction through enhanced circulation and decreased inflammation in muscular and adjacent tissues, potentially fostering the relaxation of hypertonic muscles. Certain research indicates that LLLT may modulate the release of neurotransmitters crucial to muscle contraction and relaxation processes.

Conditions

• Stroke

Interventions

Type	Name	Description
OTHER	low level laser therapy	patients will receive LLT. The LLLT system used in the study (ASA LASER M6) delivered 1.0 W in continuous wave at a wave length in the near infrared of 808 nm. The incident power density will be 670 mW/cm2.The probe head will held with light pressure in contact with the skin over the course of median nerve on the dysfunctional limb for 15 minutes. Protective goggles will be used to prevent direct eye contact of the laser beam. plus selected phyiscal therapy program
OTHER	selected physical therapy program	patient will receive standard physical therapy program for wrist flexors spasticity post-stroke typically includes the following components: Passive stretching: Passive static or dynamic stretching of the wrist flexorss is the mainstay to reduce spasticity and Physical therapy exercises in form of specific techniques of proprioceptive facilitation, relaxation techniques, passive and self-passive motions, and proper limb positioning. plus sham low level laser therapy
