The study was conducted to identify the relationship between wrist flexor spasticity and hand function in patients with stroke. The wrist flexor spasticity was assessed by Modified Tardieu Scale which is a valid and reliable tool. The hand function was assessed by Action Research Arm Test which also a valid and reliable test . The scores of both were analysed and correlated by Pearson Correlation Co-efficient .The results of this study stated that there is a weak positive correlation between wrist flexor spasticity and hand function. There is a weak negative correlation between elbow flexor spasticity and hand function.

 The results of the study are similar to the few studies conducted before and support the finding that spasticity does not influence the function of the hand. Few similar studies hypothesize that the spasticity manifests more when the limb is at rest. When the activity starts the strength predominantly comes into picture. This may be of one the reasons why weak correlation between these two variables is seen. The presence of spasticity in one position may not predict spasticity in other position. The grip and finger strength is also required to perform the function of hand. The strength maybe reduced because of the paresis and also the shortening of flexors. Thus, the muscles are unable to produce the required strength for the task.

Thus, the study concludes that spasticity does not affect hand function in stroke patients.Considering the limitations in this study, future studies can be conducted where the strength of upper extremity muscles can also be measured. More factors which influence the hand function can be assessed. The study population was sub-acute stroke. Further studies can be conducted considering chronic stroke population.
